Closure article and application thereof

[Detailed Description of the Invention]

the present invention relates to the Crozier article and its use -- further -- detailed At least one copy is related with the method of sealing the end of covering of the connecting part between the bases using the Crozier article and it which have a means to be heat recovery nature and to hold the countering portion of the end to one between the bases which it let pass there. For example, many examples for which it is needed capsule-surrounding or making a long and slender object like a cable or a pipe seal for the object of a seal, an insulation, or protection exist. Such packaging operation turns into important work especially, when combining the pipe or cable containing the joint especially provided with two or more pipes or cables, for example or carrying out a heavy patch. As for the end of a long and slender object, in many cases, it is common that it is in the situation where a tubular sealing member cannot be put. in addition -- in the following statements -- the above -- the thing of a long and slender object will be named a cable generically. Of course, the application field of the present invention is not limited only to a cable, and also includes the connecting part between long and slender objects, such as a pipe, a duct, and a lead pipe, especially these long and slender objects. it is the above, in order to conquer above-mentioned fault and to carry out the seal of the cable bonding link -- various sealing members for packing the surroundings of a long and slender object are developed. The sealing member of a statement is mentioned in United States patent No. 3.379.218, No. 3,455.336, and the No. 3,770.556 specification as such a sealing (closure) member. these -- what is called -- "-- the surroundings of the object can be equipped with (wrap -around) J sealing member by twisting, without using the free end of a long and slender object. However, it is without it uses the free end for the heavy patch member which built in two or more ON Cuckoo ends and/or heavy patch parts also between the cables of a different size, It is still anxious for the improvement to the object for the electric wire cable joint for protecting from the external world effectively, or the sealing instrument for a heavy patch (the following "heavy patch case" (splice case) is called.). An object of the present invention is to provide a heat recovery pile patch case generally. Re-equipping is also possible, without being able to remove such a case from the cable as well as storing two or more cables of various different sizes, i.e., an outside diameter, and using a cable end part depending on the case. The method of the present invention differs from the method "to twist." The above-mentioned "twist" method of the present invention is because it piles up and inherits by a different method a little and capsule packing of the portion is carried out. The heavy patch case concerning some embodiments of the present invention uses the method which uses the method "sealed like a shellfish lid", or uses a separate base plate and hippo 1 member. A heavy patch case performs a recovery operation around a cable or other heavy patch portions, when it is exposed to an outside heat source like for example, a propane flame or hot wind air, and it is made to have packaging operation performed according to one embodiment of the present invention. The heavy patch portion is located in the portion which a comparison promissory note does not reach easily, or is placed on many examples of application of a heavy patch case by dangerous environment, and the case where it is quite difficult to equip with a heavy patch case is included in them. For example, the case where an overhead telephone wire cable is connected, and in the case of the connection work in the coal mine and other places where the gas of flaming nature is contained, as a time, using a flame for recovery of the case is not only often accompanied by danger, but it may have to avoid absolutely. In the bottom of such a situation, it is especially preferred with firewood that it is not necessary to use external heat, especially a flame in wearing of a sealing member, i.e., a heavy patch case. Therefore, in the desirable embodiment, the heavy patch case concerning the present invention is provided with the fixture heating device. That is, it is possible for the heavy patch case to really contain the electrical resistance heating machine matter of a formula, to generate, and for this opportunity matter to pile up and inherit heat, and to recover a case, when connected to the suitable source of an electric power supply, and to carry out capsule packing of the heavy patch portion. It is possible to make it recover only by this heat recovery pile patch case not needing the source of external heating, instead connecting the case to a power supply. In this case, it is good also as 115V or other suitable sources of exchange, and the case is recovered when connected to such a power supply, as a power supply, it can also be considered as the battery of 12V or 24V, and the adhesives or sealant on that inner side surface is activated. the case where the material which gives the integral-type heating machine matter used for the heavy patch case concerning the present invention is prepared - combination and composition from which a heating operation [ like ] is obtained become important. In order to activate adhesives or sealant thermally using heating machine matter and to produce heat recovery of a case simultaneously in addition, high temperature must be obtained like comparison about 120 degrees C~200 degreeC, and it is necessary to perform temperature control strictly. When the temperature beyond the above-mentioned temperature range required for a heat recovery operation of a heavy patch case and activation of adhesives is reached, permanent damage may occur on some of seal objects, i.e., heavy patch case, and/or seal objects. such damage cannot be discovered only by checking visually the heavy patch case and the case proximity portion of a cable which were boiled occasionally, were carried out and were recovered It is possible to control the temperature of the object which adopts a thermostat and/or other thermal control devices, and it is recovering, and the object which it finished recovering. However, in many cases, when performing such control, the heavy patch portion which uses a formula with built-in self, i.e., a self-heating type obturator, is received, it is alike occasionally and carries out, and grounding is difficult in practice and a high price and the fault that the temperature controller of an external operation which is sensitive and/or bulky must be formed arise at a point. It will be limited very much to a neighboring temperature, and other fields of a case will be quite lower than a desired temperature, or the fault of the device which becomes a high temperature will produce a temperature detectable with the above-mentioned control device. Use of the self-regulation type heating device is considered in the use of the latest electric new heating. This heating device uses the plastic material in which the electrical resistance characteristic of a right temperature coefficient is shown. Such the characteristic will be henceforth called PTC. Such a material is usually formed from crystalline thermoplastics, and the conductive detailed bulking agent is contained in this substance. When the remarkable characteristic of such PTC materials reaches a certain temperature, I hear that a rapid increase arises in resistance to it. Thus, the temperature to which resistance increases rapidly is often called switching temperature Ts. It is because the tendency for current not to flow at this temperature arises. Therefore, the object currently heated by this opportunity matter itself or opportunity matter currently heated can be prevented from carrying out a rise in heat further. Although various theories are considered in order to explain such a phenomenon, According to the idea currently believed most widely, a rapid change of the resistance beyond the point of PTC material fusing [ crystal ] should have arisen according to the difference in the coefficient of thermal expansion between the conductive bulking agent and thermoplastics matrix in a fusing point. About the more detailed argument on the mechanism of the phenomenon of PTC, For example, "Glass Transition Temperaturesas a Guide to the 5 election of PolymersSuitable for PTCMaterials" (J, Meyers.) Polymer Engineering in 5cience and the November, 1973 item (13 No. 6) are referred to. Many self-regulation type heating devices which use PTC material use steep slope curvilinear R-f (T) at temperature Ts, and the heating device does not send pigeon But current in practice more than this temperature. On the other hand, power consumption which was fixed in comparison to predetermined voltage to below this temperature is shown. The electrical resistance of a device is on a comparatively low fixed level in the degree of low temperature, and current becomes comparatively high to any voltage. It is emitted in the form of heat and the energy to generate warms case material in that case. Resistance remains in a comparatively low level, and if it reaches temperature Ts, rapid increase of resistance will generate it, until temperature reaches Ts. If resistance increases, a power amount of consumption will decrease and the occurring quantity of heat will be regulated. In this case, in the case of the slope in which the curve of R-f (T) is very sudden, it is stopped in practice by the heating effect. If temperature falls, shortly, resistance will fall and a power output will increase. PTC opportunity matter is rapidly heated by the thermal energy generally emitted when voltage was applied to PTC heating machine matter even at the switching temperature, and most rises of temperature are lost for rapid increase of subsequent resistance. For rapid increase of resistance, theoretically, the above-mentioned heating machine matter reaches the regular temperature near switching temperature, and it can carry out self-regulation of the heat output, without depending on a means like a fuse or a thermostat. A thermoplastic PTC material used in this industry so far is extremely rich in crystallinity, and shows Ts with the point fusing [ Hub crystal ]. However, the greater part of such a material has a "chip box bend j (curlover) effect in fact. That is, resistance decreases again at a temperature quite higher than the above-mentioned fusing point. Thus, it is not desirable, and it is a case where especially the PTC material itself is heat recovery nature, or when used for making heat recovery material approach and carrying out heat recovery of this, it is not generally desirable [ the phenomenon in which resistance decreases on a fusing point ]. It is because to make heat contraction material heat to the fusing point in such a situation as quickly as possible, to make the temperature of a heating device keep to a temperature slightly higher than the melting temperature of the thermoplastic parts of a heating device, and to shrink a heat contraction object quickly and effectively after that is desired. However, when carrying out capsule storage of the heavy patch portion between telephone wire cables and carrying out a seal from the external world, using the heat recovery material used in the present invention, the method of contracting and adhesion combining the heavy patch portion is usually used for a cable jacket using adhesives. The above-mentioned cable jacket is usually amorphous on a partial target like for example, carbon black restoration ethylene / vinyl acetate polymer, and has a thermoplastic ingredient of a low melting point here. Such a cable jacket is in the state where it does not crosslink, almost certainly, therefore when it reaches the high temperature that jacket temperature exceeds the melting point in the rise-in-heat period for activating adhesives, it will be mobilized, and it will be distorted easily. When to pull apart the source of power from a heat contraction object carelessly has been forgotten using a heating device without a positive interception operation, a still more serious result will arise. Under such circumstances, the situation to be energized exceeding time (for example, for 10 minutes) required to end capsule packing will generate a PTC heating device. When each of such a telephone wire cable is insulated by the similar thermoplastic ingredient, a still more serious result is brought about. The above lead jackets are distorted, and since the portion of a cable does not make [ hear / I / that it becomes ] business and there is, being twisted is a situation which must be avoided absolutely. Therefore, the desirable characteristic required of the heating device for heavy patch cases, First, more than Ts temperature of heating machine matter, resistance is rapid, and continues and increases, Without a steep slope showing for some the what is called "chip box bend" characteristic which inclines gently, as almost all the conventional heating devices were so, it is the characteristic of holding the increase tendency of resistance until the sensitivity of heating machine matter rises beyond the fusing point of an above-mentioned thermoplastic ingredient. It seems that the fault which occurs until now in connection with an above-mentioned "chip box bend" phenomenon and the phenomenon is not recognized widely. It seems that the following thing can also be said if an idea is advanced. Namely, conductive polymer material provided with the PTC characteristic used so far, Only insufficient calorific capacity is had and carried out also to activation of high temperature adhesives which is provided only with calorific capacity insufficient for producing heat recovery of the portion of heat recovery material like the heavy patch case where the present invention is applied thick, in comparison, and is performed in the present invention. Most faults which arise by using the conventional PTC material for an article like the heavy patch case of the present invention use [ Japanese Patent Application No. / No. (JP,51-60236,A) 116270 / 50 to / concerning these people ] the material of a statement, And it is conquerable by using [ Japanese Patent Application No. / No. (JP,51-76647,A) 116271 / 50 to ] the structure of the form of a statement. However, although the conventional PTC material is not a not much desirable material, it is also possible to use such materials for the heavy patch case concerning the present invention in many cases. When each lead of especially the cable is covered with the insulator based on paper at the time of use of a telephone wire cable, it is necessary to eliminate humidity. When the humidity content contained in the insulator of a wire exceeds a critical level low in comparison, it is because the electrical property of a wire deteriorates in the degree of seed inevitably. Before usually piling up, inheriting, carrying out and sealing a cable as a measure against number To be on account of this reason, the method of piling up and inheriting the small paper bag into which a little dehumidification agents (usually silica gel) were put, and inserting in a portion exists. In this case, what kind of thing is external humidity, and, as for the quantity of the dehumidification agent in a paper bag, sufficient quantity to keep the humidity in the portion on a very low level is chosen over all the life periods of that and the heavy patch portion. About 509 silica gel is used in a typical example. Although it is making it expect in the method of using such a dehumidification agent naturally, It often happens to forget to put in a dehumidification agent, and the paper bag is neglected, forgetting to put in, suiting and having forgotten the seal of an important paper bag also in the case, equipping with the paper bag which the paper bag piled up and inherited in the state, and the portion was equipped, or was dropped underwater or into mud when extreme as it is Or -- And -- the situation to say and which is not preferred occurs. According to the desirable embodiment of the present invention, such a problem is completely resolved. Now, if it has a still more detailed discussion, and humidity increases extremely, the performance of a paper insulation cable will fall to a degree very much. That is, on the ambient conditions of 30% of relative humidity, and 15 degreeC, it is often used by a telephone wire cable, and the insulation resistance of filter paper insulation Stranded wire falls to the about 0.5-giga ohm per length lkm. At 30% or less of relative humidity, performance is satisfying. There is not necessarily the necessity of making humidity within a heavy patch case into extremely low humidity, and it became clear that it might only hold to 30% or less. If a dehumidification agent is enclosed in a container in this case, and the steamy transfer characteristic of this container is piled up and inherited and it was made to match with the characteristic of the case itself carefully, it also became clear that it could hold to 30% or less as the relative humidity within the heavy patch case is shown in the following explanation whatever the outside humidity. In 100% of relative humidity, the outside of a cable is [ an inner side ] 0% of relative humidity, When humidity steamy transfer rate MVT of the typical heavy patch case concerning the present invention is 100 microg/o'clock in 15 degreeC, MVT of the container of a dehumidification agent must be 100 micro more thang/o'clock at 30% humidity, and it must be 333 micro more thang/o'clock at 100% humidity. In this way, if the MVT value of a dehumidification agent container is 500 microg/o'clock, above-mentioned conditions can be satisfied. The above-mentioned container contains a dehumidification agent like about 100 g of silica gel temporarily now, and it is assumed that the dehumidification agent can absorb moisture of about 50 g. When it is stored in the state where relative humidity is 100%, now and any protective covers of other are not attached to the container, the water absorption capability of the dehumidification agent in the container is reduced by half among about 6 Noon. When the container of such a form was piled up and inherited in this way and it fixes eternally inside a case, That protective packaging is torn off at the time of storage of this heavy patch case, and even if it neglects it for many months until it results in use, no [ validity / of the case ] substantial fall will also occur. as the especially useful characteristic of the self-heating pile patch case concerning the present invention -- these cases -- prospective -- re--- an usable thing is mentioned. In re-using a case, for several minutes, electric interengagement and (supposing it was left behind) a clip member may be removed to waiting and the next, and it may divide the upper part half and bottom half of a heavy patch case of a half-segmented type into them until it only connects the heavy patch case to a power supply and adhesives become soft. If it is a request, a correction required for each heavy patch portion is added, or it is after [ a certain ] being, being able to creep and exchanging that part, It is possible to assemble all the heavy patch cases again, to make the layer of adhesives revitalize by connecting this to a power supply for a short time, and to form a case assembly object in one without damage again. The place which the ease of this re-use means is being able to hold an excessive cable wiring portion in the extension state using a plug, when all cable Pair are not needed at the time of early installation. Then, the seal of the parts which the sex added the cable which should be attached at any time when the case was re-used, and were newly added can be effectively carried out like the original parts. If adhesives are re-fused using an outside heat source, it is possible to also re-use a non-self heating type pile patch case. In this way, the 1st object of the present invention is to provide a heat recovery obturator suitable for carrying out capsule packing of two or more cables of various sizes. The 2nd object of the present invention is to provide a heat recovery obturator with the self-heating capacity which is not in being able to twist around the surroundings of a cable, being able to insert on a cable, and being dependent on an outside heat source, and can carry out the seal of such a cable. The 3rd object of the present invention is to provide the self-heating obturator which self-regulation is possible and it does not overheat so that permanent damage may not be done to the article by which capsule packing is carried out, and can be intercepted at a temperature uglier than preset temperature. The 4th object of the present invention is to provide the Crozier article in which sufficient seal is attained in the terminal part. According to one gist of the present invention, it had the formula heating device with built-in self preferably, For example, without being dependent on a complicated temperature controller, in order to make a heat output regulation possible, it is preferred [ a heat recovery article like a heavy patch case is provided, and / the heating device ] to have a material (PTC material) provided with the right temperature coefficient about resistance. Shape of the above-mentioned article is made into the shape which can carry out the seal of the heavy patch portion by piling up and inheriting, and arranging and carrying out heat recovery around a portion. "A heating device with built-in self", or "self-heating" When the becoming term is used, When the heavy patch case provided with such the characteristic connects this to a suitable source of electric power like a battery or an exchange power supply, Building in the electrical resistance warming unit which can be made to generate sufficient quantity of heat to activate the adhesives which shrink the portion of the case which can be contracted and exist in the case (for example, fusion) is shown. In the present invention, although the heavy (that is, it does not have electrical resistance machine matter) patch case which is not provided with the self-heating characteristic is also provided, a contraction operation and an adhesives activation operation are attained via an outside heat source in this case. The above-mentioned conductive polymer material shows the right temperature coefficient about resistance, and length and width are large as compared with the thick taste, and, as for the shape, being provided with the form of a layer or a sheet is preferred. An electrode is provided, the inside of the thick taste of material is passed for current, namely, when the material is carrying out the form of the layer or the sheet, it is preferred to make it current passed from the - surface to other surfaces. It is the material by which the dimensional change was thermally carried out to the heat recoverable part of the above-mentioned article from the stable shape state, or the material thermally formed in the unstable size state, and when all apply heat, it is preferred to comprise a material recoverable to stable shape. at least 1 portion of the material which forms a heating device -- the above -- thermal -- a size -- it is preferred to form the unstable above-mentioned article portion. Of course, the characteristic of each heating device, the component, and the electrode should be determined about each case, taking into consideration the character of the source of an electric power supply which a user can use. It is good that it is a crystalline polymer, and if composition of the above-mentioned material may be able to be performed, it is good during the composition to distribute carbon particles, especially carbon black. The above-mentioned polymer constituent is good to be crosslinked by the chemical means or the radiation operation, and it should determine the kind of polymer and electric conduction particles, and the rate of the particle, taking the last usage and the kind of power supply acquired into consideration. When the surface portion of the base covered and the facing above-mentioned article and the article are fixed on the base, As for each surface portion which contacts mutually, it is desirable to have the enveloping layer of thermal activation sealant or adhesives on it, and, as for these sealant or adhesives, it is preferred to be activated at the recovery temperature of the above-mentioned article. It is preferred that the device for the above-mentioned surface portion which contacts mutually to carry out Conservation maintenance of these surface portions of each other into a recovery process is formed. Into the central part of the above-mentioned article, it is preferred that the stable inserting member is provided thermally, It piles up by this inserting member, and inherits, a cave is specified into a portion, and, as for the shape of an end portion, on the other hand, it is preferred to be chosen so that it may recover separately to each surroundings, such as a cable which pile up and inherit and is combined with a portion. The above-mentioned heating device is good to have the following two layers by the self-regulation formula. The 1st layer: Nuclear layer has a positive temperature coefficient about resistance, and comprises a conductive polymer material which is carrying out surface contact with at least one surface of Nuclear layer. The 2nd layer: Nuclear layer is formed from a conductive polymer material which was substantially provided with fixed resistance until it resulted in the recovery temperature of the above-mentioned article at least, was made to be obtained in the fixed rate of power consumption as a result substantially in predetermined voltage, and was provided with at least a pair of electrodes. The pair of electrodes are allocated so that the current which passes through between these electrodes may pass through the inside of at least 1 portion of the above-mentioned rate material of fixed power consumption and it may flow into the surface of another side from one surface of the 1st layer of the above. The 1st layer of the above is provided with a fixed electric power consumption rate layer which carried out surface contact. Each of the above-mentioned electrode touches the fixed electric power consumption rate layer. As for the above-mentioned article, it is preferred that the insulating layer is included, and it can also make this insulating layer the thing of heat recovery nature. As for the above-mentioned article formed according to the present invention depending on the case, it is possible to also make an external heating device recover, and it can omit a conductive layer and an electrode in this case. As for the formula heating device with built-in self, it is preferred to have the polymer that diffusion distribution of the conductive bulking agent it is made to have current passed as another specification in predetermined voltage (for example, 12V or 24V voltage from a battery) in the polymer material is carried out. In this case, since the polymer has sufficient resistance at that operating temperature, the heat output of polymer makes even that recovery temperature able to heat the portion (several millimeters Oda) of a heat recoverable material thick in comparison, and it can recover it around the heavy patch portion which should carry out capsule packing. In addition, as for the above-mentioned heating device, it is preferred to enable it to be given sufficient heat output to activate high temperature thermoplasticity, thermosetting adhesives, or sealant. in order to acquire the heating effect in which the 2 direction size is large like for example, a sheet layer in the shape of PTC material, and current is uniform when a one-way size is comparatively alike and is made small -- the account of the upper -- passing along with a small size portion is preferred. When a current flow occurs over the plane of a PTC material layer, since heating is locally performed along a specific electric conduction way, the heat output distribution which is not uniform will be obtained. When such fault occurs, most heating cycles will become invalid. When material Ts humidity super-Well and waits along the line which crosses the passage of current as a result of local heating, current becomes impossible [ further passing through the passage ], and a heating device will be intercepted as a matter of fact after all until the temperature of "Heat wire" formed in this way falls below to Ts temperature. In other words, the above "Heat wire" which crosses the material layer between end electrodes intercepts that of a heating device as a matter of fact, even if only some [ mere ] surfaces of Nuclear layer only reached Ts. If such a phenomenon occurs, a heating operation of a heating device will become very insufficient, and a core heating device seems to have only very small heating capacity as a matter of fact. Such fault can be prevented by allocating PTC material between electrodes so that the length of the electric conduction passage which "Heat wire" produces can be short-Nuclear(ed) as much as possible. In order to acquire the maximum efficiency to the minimum current path length, it is necessary to make small the length of a material layer, and the ratio of the thick taste. This condition can be satisfied when an electrode inserts PTC material for example, in sheet material. However, since current path length is short, and since material list area is regulated in a certain case, when the input of the source of electric power is low, a possibility that the heating effect may become insufficient for such shape exists. the material which gives the fixed rate of power consumption, i.e., a Joule-heat output, in predetermined voltage in order to make such a problem resolve -- if it puts in another way If material without the PTC characteristic is laminated on a PTC material layer, the obtained lamination member can have good heating efficiency, and moreover, self-regulation can be carried out so that Heat wire may not be generated. Please refer to the above-mentioned Provisional-Publication-No. No. 5176647 gazette for the still more detailed argument about the advantage of passing the inside of a layer without meeting the longitudinal direction of material in current, and the advantage of forming material in layers. Please refer to above-mentioned JP,51-60236,A about the still more detailed argument of PTC material with appropriate using it as a layer member which is used in the present invention and which is used especially in a high temperature use. Such a constituent comprises a mixture of the thermoplastics in which diffusion distribution of the conductive material is carried out, and the charge of an elastic material inside. Such a mixture shows rapid resistance increase in the fusing point of that thermoplastic ingredient, and even if this increase tendency exceeds the fusing point temperature, in addition, it is maintained, as pointed out in this specification. Since such a mixture material is provided with the safety that resistance increases further also at the temperature beyond the fusing point, The heating device using the material can be designed to acquire the "switching" effect at the temperature beyond theoretical Ts point, and, unlike the example of a design using the conventional PTC material, fear of thermally damaging does not occur in this case. Such a heating device, especially the heating device which resistance increase produces very rapidly at the temperature more than Ts temperature are "insensible to a command" very much. That is, the operating temperature of PTC material hardly changes with change of thermal load. These heating devices can be designed to generate very high thermometer until it results in Ts point when it connects with a power supply. Since these heating devices are excellent in the temperature control facility, adhesives are activated, Even if a heat recovery device which is applied to the present invention is made to recover around a base like for example, a thermoplastic telephone wire cable jacket and it moreover keeps connected to a power supply considerably for a long period of time, it can be used for fusing the base or not being made not to make it change. To the above-mentioned heavy patch case, various seal means containing above-mentioned adhesives are employable. Refer, for example to United States patent No. 3.379.218 and the No. 3.455.336 specification for it about such a seal means so that such a seal means can also bear the heat recuperative strength at recovery temperature. A capsule packaging device and a method of a heavy patch member concerning the present invention differ in a conventional device and a method substantially. Therefore, it is possible to conquer thru/or prevent some of faults peculiar to these conventional devices and methods to some extent. For example, the heat recovery member which was placed on the surroundings of a substrate like a cable according to one of the desirable embodiments of the present invention, The above-mentioned base is wrapped in the state where it is turned up, and the heat recovery surface which faces does not contact mutually, but it contacts the surface on which the long fingered portion which forms Ridge on the surface where a non-heat recovery base member corresponds faces. In order to keep the field of the heat contraction member which touches mutually that the cave containing the heavy patch portion of a cable should be specified in some desirable embodiments, and a heat stability member from being heat contraction nature in itself, Although sealing or a heavy patch case is formed of the combination of the Ryobe material, prior art is a greatly different point so that clearly [ such a feature ] also from the following description. when insert a heat recovery member into the surroundings of a base until now, it covers or it contracts, the field where the above-mentioned heat recovery member is fixed with a hermetic seal member is mechanical -- weakening -- change of a field and the external world, for example, weakening about the resistance over invasion of water, -- it has been believed that a field is formed. In above-mentioned United States patent 3.455th and No. 336 specification, the method of solving this problem by obtaining a long disclosure passage is indicated by by providing the overlapping flap member under the contact end of a heat recovery member, and fixing to an overlap layer via adhesives. However, such a method does not act well, when it does not act as a basic member in which the above-mentioned base became brave, but the above-mentioned heat recovery sealing member forces the above-mentioned flap to this base, adhesives cannot mobilize and the contact surface cannot be leaked. such a fault element -- in addition -- the case where the difficulty of constituting many input pile patch cases provided with the heat recovery field with which it overlaps is added When the most, of course, even if the article constituted according to the No. [ 3,455.336 ] above-mentioned patent is useful, it can solve no problems which the present invention has solved. According to the desirable embodiment of the present invention, these problems have been solved by the very easy and effective method. It is possible by providing intervention Ridge thru/or a finger on the above-mentioned non-heat recovery base member in combination with the clip on a heat recovery member, and a flange as another specification for it to be easy to obtain an above-mentioned desirable result. As explained previously, thermal activation sealant or adhesives are preferably applied to the surface portion in contact with both articles. However, the sealing portion between the materials in an article end may be especially pulled apart by the recuperative strength at the time of recovery of an article. Then, according to the gist of the present invention, it is the method of sealing at least two ends of covering of a connecting part between bases along which 2 or a long base beyond it passes, and the covering is arranged around the connecting part, and is heat recovery nature at the end at least. At least one end of comprising an article which has at least two openings which insert each of a base at each end at the time of heat recovery, and there being the article [ method / before / recovery of the article ] between at least a pair of bases (however, they are no ends.). Outside a countering portion, at least one clamp device for holding the inner surface of the portion in seal relations during recovery at least is supplied to up to the surface, Subsequently, the method and at least two ends which comprise heating the article, recovering and sealing to the circumference of a base, and sealing the countering portion between bases are at least one end of the member of heat recovery nature, and the member. (however, they are no ends.) -- having a clamp device for holding a countering portion to one It is the Crozier article which can be arranged to the circumference of a base in the connecting part of at least two long bases, A member has an end which has at least two openings which can insert each of a base at the time of heat recovery, and is an end of a member, The countering portion of the end between the base which was recovered around the base inserted in the end, and was inserted in the end, and at least a pair of bases can be sealed, and it is a clamp device, It can arrange on the surface outside the countering portion of the end between the bases of this pair, and the Crozier article holding the inner surface of the countering portion in seal relations during recovery of a member at least is provided. Although the article whose at least one copy here is heat recovery nature may be a heat recovery article of the present invention explained previously, they may be other constituted heat recovery articles. As a means to hold the countering portion of an end in seal relations, a clip especially a spring clip, a clamp, especially a hinge clamp are used, for example. If it explains with reference to an attached chart, it has an expansion central portion for the heat recovery obturator constituted according to the present invention being shown in Drawing 1, and making it the device have two or more cables stored, and storing the heavy patch portion between cables. Such shape is suitable for especially applying many cables to the low-voltage telephone wire cable which needs to be combined at low cost quickly and effective moreover. The device shown in Drawing 1 can form the whole from heat recovery material, and it is preferred that a self-heating constituent which the material is shown in Drawing 5 at that glabella, and is explained in full detail below in this case is included. it piles up as an exception method and inherits, and the central portion of a case is made into non-heat recovery nature, and is Facial of the case -- only the case both-ends portion shown, each end portion, i.e., dotted line 18, which form a portion, can also be made into heat recovery nature. The layer of heat recovery material is crosslinked by radiation operation, for example in order to make this heat recovery nature. the heat recovery portion containing layer IO is "Facial as shown in Drawing 2 -- it is fixed to stability and a non-expanding state provided with Jll. it is Facial of the above-mentioned non-expanding state -- Is -- natural -- sufficient surplus material portion to expand from now on is included -- Sports -- as long as it is, what kind of shape may be taken. they are these Facial -- as shown in Drawing 3 of Is, it is expanded by known technique to a larger size than the diameter of the cable which should be carried out a seal. Since heat recovery material has sufficient flexibility and elasticity, a cable can be pushed in into an opening in Facial. The above-mentioned opening can make a different size according to the size of the cable which should be inserted have as shown in Drawings 3 and 4. However, it becomes possible by [ one ] carrying out heat recovery only of the size to apply to the cable of a wide range size. Heat recovery part 10 is used in combination with heavy patch case bottom part part 12 of non-heat recovery nature. However, in some examples, this bottom part can also be made into the thing of heat recovery nature, as shown in Drawing 7. It is also possible for bottom part 12 to give rigidity to a cable pile patch portion, and for it to be able to achieve the duty as a member made to equip with this eternally. As an exception method, part lO and 12 can be provided with a collaboration hinge in end 14 (Drawing 4). As for these parts, when part lO and 12 are formed from the same material as an exception method, it is possible by using a seal means in end 6 to also make it unify in end 14. Or what is necessary is just it to be possible to also make part lO and 12 separate separately in both ends 14 and 6, and to only lift heat contraction part lO from part 12 in this case, in order to insert a cable. If it is a request, in end 14 and the six neighborhoods, a strengthening strip can also be preferably embedded part lO and 12 along a longitudinal direction axis. Such a strip can act also as Bus Bar. In order to carry out the seal of the cable pile patch portion in accordance with the method of the present invention, first, parts 10 and 12 are separated and cables 20 and 22.24 are inserted. In these figures, reference of especially Drawing 2.3.6 does not unify thru/or hinge combine parts 10 and 12. For example, hinge clamps 52 and 54 are used as a clamp device, and such a Ri lamp is bound tight via bolt 56 and butterfly Nut 58. These clamps can achieve the duty which holds parts 10 and 12 in expansion (Drawing 2) of a cable, insertion, and recovery (Drawing 4) distance. As for these clamps, although such a Ri lamp can also be made to form as permanent parts of a device, it is preferred to remove after cable wearing, for example, to carry out the seal of the end to United States patent 3.770th and No. 556 specification eternally with the adhesives of a statement. In the above-mentioned end, in order to secure the proper interval between cables, it is convenient to use a clamp device. this clamp device is Facial as Drawing 6 is shown best -- it is possible to consider it as plate separator 62 provided with the opening which can store 11 inside Such a plate can make clamps 64 and 66 carry out the seal of part lO and 12 firmly during the expansion and sealing work. In order to give intensity to a heavy patch case, to protect this, to have a humidity transfer prevention operation if needed or to provide an electric wave shield, The specification which carries out capsule packing the whole case into the rigid body can provided with the outline specified by dotted lines 18 and 18a located in the cable pile patch portion itself as another specification under the heat recovery member central portion shown with 1st [ The ] figure numerals 26 is also possible. When central portion 26 is heat recovery nature, this portion can suit the shape of the above-mentioned can. As for this can, it is convenient to manufacture from metal or a rigid material like a forming plastic. It is made for end openings 19 and 21.23 to have each cable of a different size stored. The other end of the heat recovery member contains the opening provided with the same size, in order to store the cable which should usually be combined. But it is also possible to centralize all the openings on one side. When a rigid body can is used for covering a heavy patch portion, it is not required to carry out the seal of the central portion by a heat recovery member. Therefore, as mentioned above, the portion which can heat recover the article concerning the present invention can be limited only to an end portion, and the article can carry out the seal of each ON Cuckoo to a can by carrying out like this. In the case of this case, central portion 26 can be made into non-heat recovery material, and though it comprised heat recovery material, it is not necessary to make it recover. As a can is crossed and material cannot be made to be able to project as an exception method, it keeps [ expose / a can ] made or only an insulating layer like layer 30 or 31 of Drawing 5 can be made to be able to project from a can, and the remaining layers can also be confined in an end. If it explains in detail about Drawing 5, since the heat recovery sealing member has the self-heating lamination member which embedded the electrode inside, it will be preferred, and let the electrode be a thing connectable with a suitable power supply. Please refer to above-mentioned JP,51-116271,A for the details of the above-mentioned lamination member. If it says simply, the above-mentioned lamination member comprises outside insulating layer 30 in which heat recovery is possible. Layer 34 has a polymer mixing object or polymer like a mixture of polyolefin and ethylene propylene rubber which was extremely rich in crystallinity, for example. Conductive carbon black is distributed by inside of these mixtures. As for layer 34, in order to control a heating operation, it is preferred that a positive temperature coefficient is shown about resistance. As for layer 34, it is preferred to be inserted in among layers 32 and 36, and it can be used as the polymer mixing object in which Nuclear layer 32 and 36 also diffused carbon black here inside. As for these layers, it is preferred that the fixed rate characteristic of power consumption is shown to predetermined voltage over the wide temperature range, and an extreme positive temperature coefficient is not shown to resistance. It is also possible to provide inner side insulating layer 31. It is preferred for heat recovery to be possible also for layers 31, 32, and 34.36. The above-mentioned inner side layer is good to include the adhesive coating layer (not shown) for the cable on a layer free surface, combination and in order to carry out a seal. Electrode lattices 38 and 40 are embedded in fixed power consumption layer 32 and 36. These electrodes are connectable with a suitable source of electric power like a battery shown in diagram, for example in Drawing 6. If such wiring is used, current will turn PTC layer 34 to electrode 40 from electrode 38, and will pass. Still more detailed explanation will be performed to below about a desirable structure and shape of an electrode. Another more detailed shape about Drawing 7 which will be applied to the present invention at this layer if it explains is shown. A such-shaped member can be formed from the single sheet material provided with the layer member usually as shown in Drawing 5. After inserting the above cables into opening 44 and 46.48, this device is sealed by forcing end 50 of each other which faces via suitable hermetic seal member 51. As illustrated, of course, such a device can be constituted so that the cable of various sizes may be suited. It is possible to consider it as the "shell" structure which such a device was provided with the hermetic seal member in 50, and was provided with the self-attachment-by-hinges means in 47. The especially desirable example of the present invention is shown by the section in Drawing 8. This example is provided with the upper part and bottom members 96 and 80. Upper member 96 has outside pile patch case husks 67 firmly fixed to the warmer, and the warmer is formed from the outside of the rate of fixed power consumption, inner side layer 68, and core layer 69 of 70 and PTC material. Adhesives layer 71 is being fixed to the inside side surface of inner side layer 70. Preferably, PTC core 69 of the warmer is constituted, as it described in above-mentioned JP,51-60236,A, and it is combined with fixed power consumption type outside layers 68 and 70. The thermoplastic polymer component of these outside layers has a fusing point lower than the fusing point of the thermoplastic polymer component of the above-mentioned PTC material here. The above-mentioned fixed power consumption type layer can be made into the thing of heat recovery nature if it was provided with thermoplastic polymer. It is preferred that another outside husks 68 which have a heat recovery polymer component layer which has a recovery temperature lower than the melting point of the thermoplastic ingredient of PTC material are established. Now, as for operating temperature, although it is possible to make layer 71 of heat fusion adhesives add, the melting point of these adhesives is close to the melting point of a heat recovery member, and it is good that it is a temperature lower than the melting point of the thermoplastic ingredient of upper EPTC material. Such an example is suitable for especially using, when the basis bottom body has heat susceptibility, and is heated by the temperature more than the melting point and it mobilizes whether it changes. In a fixed power consumption layer, electrode 72 which was rich in flexibility is embedded as well shown in Drawing 9. As for the electrode, forming from a line wire more is preferred. it is each heat contractility End -- it has electrode 72 of six Is, three pieces are connected to one terminal among those, three pieces are connected to another, another terminal, in this case, these electrodes make a pair mutually, and are installed side by side, and it is running in the direction which crosses the longitudinal direction axis of a heavy patch case. An electrode provided with the 1st polarity is connected to Bus bar electrodes 73 and 73a, for example by methods, such as welding, soldering, and adhesion by electrically conductive adhesive. An electrode provided with the 2nd polarity is connected to Bus bar electrodes 74 and 74a are piled up, and are inherited and it runs covering each side full length of a case. Each of the above-mentioned electrodes 73.73a and 7474a can be formed from a Stranded wire wire or a thin metallic strip. the central portion of one electrode 73, and the central portion of electrode 74a of another side -- the connection with a power supply -- easy -- tabs 75 and 76 for making it-izing are being fixed. it is heat recovery Sexual end at the upper part of the main heat contraction layer (refer to the 8th figure) -- strengthening flange ?7.78.79 manufactured from the suitable rigid material between structures are attached. Thermoplastics for industry like restoration polymer, such as metal, polycarbonate, acrylonitrile butadiene styrene, i.e., SAN resin, for example, polyamide, or polyolefin, as the above-mentioned rigid material can be mentioned. Glass restoration polyamide (nylon) is the most preferred also among such materials. As for bottom member 80 of non-heat recovery nature, it is preferred to have outer rib 81, in order to increase rigidity, and it is also possible to make inner side Ridge 82 which suits the opening side that it will be shown in Drawing 10 as selection specification in heat recovery Sex have. In order to assemble the above-mentioned heavy patch case, the upper part and a bottom member may be united first, and it may be made to fix according to the present invention with spring clip 83.84.85 suitably constituted from a material similar to flange 77*78.79. Explanation of Drawing 11 shows the section which put on this figure, inherited and met the longitudinal direction axis of the case. Central cave 86 has a duty which stores each heavy patch wire of a cable. Small container 95 filled with the dehumidification agent as desirable selection specification is provided in this cave, through that wall surface, it is spread into the container and moisture goes at a speed quicker than the diffusion velocity into a case, as mentioned above. A valve may be allocated in cave 86 so that the pressure test of the installed heavy patch case can be done. Also referring to 12th [ The ] figure~figure 21 with reference to the example of 8th [ The ] figure~figure 11 especially, it will pile up and inherit and will explain the desirable manufacturing method of a case. For example, the electrode material which is metal Stranded wire is made to form from 16 careers preferably. each career -- four 38AWG (considerable [ in diameter of 0.01 cm ] with U.S. wire gauge) tin Metsuki copper wire -- as much as possible (in order to acquire flexibility as much as possible) It is possible to make it form from that of Twisted at high Stranded wire angle, and such an electrode material twists around the surroundings of a thin electric conduction line thru/or the thermoplastic plastic tube of non-conducting. Stranded wire angle was 75 degrees and it obtained the result with most sufficient twisting a line around the tube of the thickness of 0.25 mm which consists of the same ingredient as the above-mentioned charge of the room power consumption section bar between -, and outside diameter 6.25 Tomorrow. Next, the tube which gave winding is heated to near the apparent initial softening of a thermoplastic tube, and it is made flat, warning against lengthening the above-mentioned Stranded wire. These processes are shown in Drawing 12. The following process is a formation process of an electrode, and this process fixes tab 75 to side electrode 73a, and includes the stage of attaching end electrode 72. Spot welding, soldering, adhesion, etc. can be mentioned as a suitable fixing method. When the electrode comprised what provided Stranded wire in the surroundings of the conductive core which consists of the same material as a constant power consumption type layer and the thermal coupling method was used for combining the electrode of each other using the conductive thermoplasticity core, the very good result was able to be obtained. The process to which the electrode of each other is made to fix in order to acquire the shape used as the foundation can be simplified by using a jig as shown in Drawing 14. As the Stranded wire material material and Above which are used for an end electrode and which is made flat, the shape of textiles or a tabular metal wire, conductive textiles, the polymer fiber that carried out metal Metsuki, the conductive particle content polymer fiber which the grain direction made electric-conduction-ize highly, etc. can be mentioned. In all these examples, as for the completed electrode, when it was extremely rich in elasticity, and piles up at the time of actual installation of a heavy patch case or manufacture, it inherits and the heat recovery portion of a case recovered and expands, it is preferred that resistance is made not to be given. A similar material can be used for a side electrode. since these electrodes do not receive big modification on the occasion of installation during manufacture -- flat metal thru/or high conductivity strip A week punched preferably -- it can be made to form also from single or a multiplex Stranded wire wire The formation method of the material for heavy patch cases is shown in Drawings 13 and 14. As for these heating layers, although various heating layers can be pushed out, for example and it can manufacture by the heat calendar method, assembling within a jig frame is desirable. In the illustrated example, it does not bite outer skin layer 67, but is fixed in a frame, the [ next, / constant / power consumption layer 68a1 ] -- electrode sets 73/73a (as shown in an attached chart, tab 75 has turned to right-hand side) of one, the [ another constant power consumption layer 68bSPTC control layer 69 and also / another constant power consumption layer 70a1 ] -- electrode sets 74/74a (tab 76 has turned to left-hand side) and the constant last power consumption layer 70b of two are accumulated one by one. All the structures are inserted between polytetrafluoroethylene protection layers 97 next, and are mutually laminated by pressurization heating. A jig is used in order to make these various layers and electrodes hold in the stage laminated mutually. If lamination is completed and a polytetrafluoroethylene layer is removed, the assembled case material will be inserted between effervescent sheets 100, For example, it is the temperature of 185 degreeC and is annealed over period sufficient where minimum pressure power is applied, and composition each class is preferred although he is trying to be completely released from remaining stress. Although annealing time may be changed over 2 minute~60 minutes according to material, about [ 5 minute~15 minute ] annealing time is preferred in crotch. A material is removed while this is still held at annealing temperature, and as shown in Drawing 15 below, it is forced on a male type via the pressure of the direction of an arrow. In this way, heavy patch case shape member 87 of a non-expanding state as shown in Drawing 16 is obtained. Attention must be paid [ that a warmer is not lengthened during molding operation in this process, and ]. If it is with a request, two or more tail root material and a desirable foil rust type member can be provided in the upper part surface of seven lunges 77.78.79, and the operation which turns to a certain direction the compressive force induced by clamps 83 and 85 can also be made to perform. Next, heavy patch case - In this industry for obtaining a radiation operation [ like ], it is radioactivated using the ion emission technique known well. As a suitable source of ion emission, a gamma ray, X-rays, an acceleration electron beam, etc. can be mentioned. The required amount of irradiation should be chosen so that it may become the quantity which is not superfluous like it blocks the extension phenomenon in the expansion work which is sufficient quantity to guarantee case-shaped one nature in right above [ of the polymer component part of a case / fusing / crystal / point ], and it makes form in the shape which can heat recover the case. According to the result of the experiment, the amount of proper irradiation was 2~50 megarad, and was 5~20 megarad preferably. The material after irradiating with radioactivity is "thermally stable" shape, and the material is fabricated to shape member 88 "heat recovery is possible" in the process of operation shown in The 17th figure~figure 19 below. After preheating article 87 even to the crystalline melting point mostly, a formation material is inserted into jig 89 shown in Drawing 18. As shown in Drawing 17, strengthening 7 lunge 77.78.79 which gave adhesives layer 90 to the contact surface is fixed on the side of material 87, and an end. End flange 78 is equipped with long tab 91 "which carries out a chip." The tab 91 has guidance hole 92 for equipping jig 89, as shown in Drawings 17 and 18. All the seven above-mentioned lunges are folded in the outside end, and have raising lip 98, and these lips are acting as an end for protecting a warmer from mechanical wounding. Side flanges 77 and 79 are provided with small side board 99 in the central outside end which encloses electrode tabs 75 and 76, The size of the side board is chosen so that for example, the "quick removal type" connector (6, 3X O, 8 mm) of the standard marketed from Arc-Less can be stored. the above-mentioned side and an end flange -- and it piles up and inherits and is case Facial -- it is alike, pressure is applied and a central cave is formed via a suitable overhang molding machine. Such extended art is well known from the former, for example, can mention art, such as mandrel extension and empty pressure thru/or vacuum pressure fabrication. In this process of operation, attention must be paid so that case Fold may not be compressed into a longitudinal direction, when a mandrel is used. in order to reduce such a compression operation, the sleeve member which could develop radially, for example or was Blooming-ized in the direction of the circumference is provided in between in the above-mentioned mandrel and case Facial, and it is Facial -- the method of distributing the longitudinal direction power induced by the portion via a mandrel is employable. The empty pressure method of being, carrying out and restraining to a longitudinal direction by an oil pressure means is considered in an elastic body tube as an exception method. As for the above-mentioned heavy patch case cave, being formed in empty pressure is preferred. As shown in Drawing 19, it is cooled while it is restrained, and then, an expansion material is taken out from a jig, and adhesives layer 93 is fixed to the inner side surface in the surface and Facial in contact with a bottom member. An adhesives layer is fixable also to the contact surface of member 80. If it is a request, container 95 filled up with the dehumidification agent can also be made to fix to the inner side wall in central cave 94 in this process step, as shown in Drawing 20. Drawing 20 shows the figure of completed heat recovery upper member 96, and if it is case Facial in this figure, it can understand a relative relation with a central cave. As an exception method, the above-mentioned dehumidification agent can also be fixed to a base plate, as shown in Drawing 11. As mentioned above, the all heavy patch case after completing a heavy patch portion, piling up and inheriting this when using it and incorporating in a case piles up upper member 96 and bottom member 80 of each other, follows the present invention, and are side clip 83.85 and end clip 84a. It can assemble by fixing mutually using 84b. Next, a warmer is connected to a power supply. the arrangement state of the electrode of a heavy patch case upper member, and the above -- a law -- a power consumption layer and a PTC layer -- for example, the lead storage battery of 12V or 24V -- like And the heating phenomenon of performing a recovery operation on account of the relative resistance between these layers when it connects with the source of electric power, and/or making it activating adhesives is With rose case Facial, it will occur in 7 lunge field. In this way, in a central cave, the power consumption which is sufficient for heating this enough does not occur. As mentioned above, as for the composition used for warmer each class, the composition which can be heated quickly is chosen in the case. for example, when an above-mentioned desirable PTC constituent is used, a warmer is Facial within a time [ for 1 minute or less ] -- it was possible to have heated a field to the temperature of 115~120 degreeC. Such temperature attainment, then a Foldable field start a recovery operation. it is Facial in about 2 minutes -- the base like Is, for example, a cable, -- contracting around the body, and also adhesives To go along being activated completely [ 8 minute~/ 13 minutes ] after, leaking a cable jacket and a non-heat recovery pace member, and beginning to carry out a seal was accepted. in a typical example, a warmer receives the source of electric power in this way -- about 10 minute ~ -- the operator was able to be connected for 15 minutes, to neglect a case assembly object in within a time [ this ], and to perform other work. Probably, as for the energization time of a warmer, it will be clear to a person skilled in the art that they are the temperature demand performance of adhesives and a thing which should be determined by thermal load and other factors. According to the result of the experiment, it became clear that the energization time required was unrelated to the temperature of the open air in comparison. It is thought that this reason will be because the interception operation of the very sharp PTC characteristic was obtained by the desirable design condition concerning the present invention. After suitable time passes, a power supply is removed, and neglect cooling of the heavy patch case is carried out even at outdoor air temperature. The side and the end clip which were used at this time by the present invention may be removed, or if it is a request, in order to further increase a mechanical protection operation, it can also be neglected in a position as it is. The special advantage acquired by combining opportunity matter according to the present invention, Since the warmer itself can be held in the specific limited temperature range regardless of the thermal load of the open air, Even if it is when this temperature range is very close to the melting point of the thermoplastic cable jacket usually used or each wire insulating material, The above-mentioned heavy patch case is the advantage that it is possible to carry out for connecting with a power supply and releasing over the period of several hours, and moreover it is not necessary to do any damage to a telephone wire wire or a cable, after ending combination of a cable. In order to make re-use easy, when re-heating a wearing member on the above-mentioned heat recovery articles and softening the member and adhesives, the restricting member which prevents a heat recovery member from being recovered completely can be provided. As this restricting member, a rigid body tongue like metal can be mentioned, for example, and these rigid body tongues are allocated by the portion which encloses a cable. If Drawing 9 is referred to, the tongue provided with flat portion 78 and the - width during a cable input is fixed on the flat portion, and the part is projected on the direction outside of an axis from the flat portion. It is possible to fix outside flat surface 77 and the tongue member same also on 79, it can be made to be able to combine with each other via the connection link formed suitably, and all the portions projected in the above-mentioned axis direction can form the arrester wires of one. If these arrester wires are requests, they can be neglected while in use.
