Fitting with connectors 5 and 9 of the sex mentioned above is united with predetermined guide rail 4 first provided in the main part of a device by using as a tip the side by which electronics package 3 is provided in male connector 5, and is made to slide in the figure Nakaya seal direction along with this. If electronics package 3 is inserted to the inner of the main part of a device, male connector 5 provided in the electronics package 3, Housing 8 of vagina connector 5 is by using female connector 9 of back wire ring board 10 for opposite -, and also inserting, It fits in, as housing 11 of female connector 9 is covered, and thereby, terminal 6 of male connector 5 inserts in fitting hole 12 of female connector 9, and both are electrically connected.

[Problem(s) to be Solved by the Invention] However, according to the prior art mentioned above, there are some problems as shown below. First, the male connector by the side of an electronics package, The center of the power at the time of pushing in an electronics package, since it is being fixed to the one side side of a printed circuit board, If it A with the center of a connector, that is, an electronics package is inserted along with a guide rail, A printed circuit board takes [ that insertion power ] the lead, and since the connector is provided in the side of this printed circuit board, the fitting direction center of a connector only becomes parallel [ the path-of-insertion center of an electronics package ], and is not in agreement. For this reason, an electronics package will receive power from the field to which the male connector is attached, and when 0 curvature curvature becomes easy to produce in a printed circuit board arises, it has the problem of having a bad influence on the Credibility of soldering connection of the field mounted part article etc. which are mounted in a printed circuit board. By the fixation by soldering to a printed circuit board, and bending, the terminal by the side of a male connector is difficult for unifying the length precisely, and becomes surely irregular. The inductance value between terminals did not gather in this, but it made unstable the characteristic in the case of high-speed communication. Since the length of a terminal could not but become long on structure, the noise became large and the terminal in a position distant especially from a printed circuit board side had the problem of reducing a communication function. It is made in order to solve the above-mentioned problem, and the present invention is insertion of an electronics package, Prevent a printed circuit board from changing from gap of a path-of-insertion center, and secure the connection Credibility of a mount part article, and unify the length of the terminal of a male connector, and the characteristic in high-speed communication is stabilized, and it aims at Challenge(ing) the outstanding connector with few noises. [Means for solving problem] In the connector provided in the inner side of the electronic device by the present invention being attached to the end of a substrate in order to achieve the object mentioned above, and inserting the substrate into the main part of a device, and the connector which fits in, A connector attaching hole is established in the edge part of the above-mentioned substrate, and it is in the housing of Connector, The mounting part which pinches the above-mentioned substrate from board thickness is provided, and the above-mentioned connector attaching hole and a free passage To shake attachment hole are established in this mounting part, Between a connector terminal and a substrate terminal is electrically connected by a flexible substrate, and it was made to coincide the center of a connector, and the path-of-insertion center of an electronics package by carrying out free passage conclusion of the above-mentioned connector attaching hole and the attachment hole of a mounting part with a screw. It is while making larger by predetermined width substrate insertion width of the mounting part which pinches the above-mentioned substrate from board thickness than by the direction of board thickness of a substrate, Suppose that a connector is attached to a floating state to a substrate by making large the path of the connector attaching hole of the above-mentioned substrate, and the attachment hole of the mounting part of the above-mentioned housing, and forming it by predetermined width from the path of the screw for conclusion. [For Work ] If a substrate is inserted in the method of the electronic device back along with a guide rail by composition mentioned above in order to fit in a connector, a connector will be subject to the insertion power of a substrate in the center, and will fit in without the connector by the side of the electronic device which counters, and unreasonableness. When it has floating structure, Even if it is A(ing) somewhat, without the fitting position of the connector attached to the device side, for example and the connector attached to the substrate suiting with sufficient accuracy in the case of this fitting operation, the connector by the side of a substrate will float corresponding to the position by the side of a device, and will fit in smoothly. [The example of real Application] Hereinafter, the example of the present invention is described using a drawing. The important section sectional view of the connector structure where Drawing 1 shows the 1st example of the present invention, and Drawing 2 are exploded perspective views of a male connector. In Drawings 1 and 2, as for a female connector and 10, an electronics package and 4 are [ a housing and 12 ] fitting holes a back wire ring board and 11 a guide rail and 9 3, since these are almost the same as usual, the same numerals as the former are attached and the explanation is omitted. 13 is the male connector attached to the above-mentioned electronics package 3, it secures an electrical link via flexible substrate 14, and conclusion fixation of it is carried out by screw 15 and Nut 16 in connector attaching hole 17 of printed circuit board 2 of electronics package 3. The fitting structure of this male connector 13 is explained using the exploded view of Drawing 2. Penetration formation of a pair of connector attaching holes 17 for attaching the above-mentioned male connector 13 to the edge part of printed circuit board 2 first is carried out. And the Bud one day used as the terminal by the side of the printed circuit board for performing an electrical link between a pair of these connector attaching holes 17 is predetermined-number-formed in back-and-front both sides. Male connector 13 comprises housing 20 which has mounting part 19 with printed circuit board 2 to both ends, and two or more terminals 21 held in predetermined arrangement, and makes fitting connection with the above-mentioned female connector 9. And the above-mentioned mounting part 19 is projected and formed in the electronics package 3 side from the both ends of housing 20, and holds the gap of the above-mentioned terminal 21 and printed circuit board 2 by predetermined width by this projection portion. And this mounting part 19 has in the center notch section 22 which has the width corresponding to the board thickness of printed circuit board 2, and it is divided into two steps of upper and lower sides by this notch section 22, and attachment hole 23 with printed circuit board 2 is formed so that mounting part 19 parted to two steps of these upper and lower sides may be penetrated. While 24 is a flexible substrate which electrically connects terminal 21 of the above-mentioned housing 20, and printed circuit board 2 and this flexible substrate 24 has arranged land 25 which engages with the above-mentioned terminal 21 in the central part, A plurality of terminals 26 connected with pad 18 of printed circuit board 2 the upper-and-lower-ends neighborhood are arranged. When it mounts male connector 13 mentioned above in electronics package 3, land 25 of flexible substrate 24 is made to penetrate terminal 21 of housing 20 first, engaging of clutch is carried out, and it connects by soldering. this state -- printed circuit board 2 of electronics package 3 -- connector attaching hole 17 -- attachment hole 23 of housing 20, and free passage To shake -- it inserts in notch section 22 of mounting part 19 like. And in order to connect these, attach screw 15, and it is open for free passage from hole 23, and is made to penetrate to the side opposite to, and it concludes by Nut 16 and fixes. Then, that terminal 26 of flexible substrate 24 should be connected with pad 18 of printed circuit board 2, bend flexible substrate 24 so that printed circuit board 2 may be wrapped, and terminal 26 is made to correspond to pad 18 formed in the back-and-front side, and it connects by soldering. By this, male connector 13 will be mounted with the structure which pinches electronics package 3 in the center, as shown in Drawing 1, and as a result, the path-of-insertion center of electronics package 3 and the fitting direction center's of male connector 13 will correspond completely. Therefore, if it inserts in the figure Nakaya seal direction along with the guide rail which does not illustrate electronics package 3 in order to fit in #la connectors 13 and 9, male connector 13 will be subject to the insertion power of electronics package 3 in the center, and will fit in without female connector 9 which counters, and unreasonableness. The construction drawing of a connector in which Drawing 3 shows the 2nd example, and Drawing 4 are important section exploded perspective views of Drawing 3. Although this 2nd example is the almost same structure about the 1st above-mentioned example, it has floating structure which the fitting structure at the time of attaching electronics package 3 to printed circuit board 2 holds in the floating state to printed circuit board 2. In Drawings 3 and 4, since each part article structure is the same as the 1st example mentioned above almost, the same numerals as Drawings 1 and 2 are attached, and the explanation is omitted, but only the thing about floating structure is described below. That is, when the crevice between notch sections 22 of male connector 13 which pinches t and this printed circuit board 2 for the board thickness of printed circuit board 2 of electronics package 3 is set to T, both size relation is made into T>L. Even if it attaches with connector attaching hole 17, screw 15 is opened for free passage in hole 23 by this and it concludes the side opposite to by Nut 16, electronics package 3 and male connector 13 serve as structure which carries out floating in the direction of board thickness of printed circuit board 2 by the size of T-t. When the path of D2 and screw 15 is set [ the path of attachment hole 23 of housing 20 of male connector 13 ] to D for the path of Dl and connector attaching hole 17 of printed circuit board 2, each size relation is Di>D. It forms so that it may be set to D2>D. Thereby, male connector 13 and printed circuit board 2 have floating structure to the path of insertion of male connector 13 and printed circuit board 2 and the direction of board thickness, and the direction that intersects perpendicularly only the part of the difference of Diameter of screw 15, and each one of paths DI and D2. When fitting into female connector 9 fixed to back wire ring board 10 in male connector 13 by the structure mentioned above, When inserting electronics package 3 in the back wire ring board 10 direction along with the guide rail which is not illustrated, it is with female connector 9 of back wire ring board lO, Even if the position of male connector 13 is not attached with sufficient accuracy, male connector 13 floats to printed circuit board 2, and absorbs a mutual size error. For this reason, both connectors 9 and 13 fit in with sufficient accuracy by inserting electronics package 3 as it is along with a guide rail. [Effect of the Invention] In the connector provided in the inner side of the electronic device by according to the present invention being attached to the end of a substrate and inserting the substrate into the main part of a device as explained above, and the connector which fits in, A connector attaching hole is established in the edge part of the above-mentioned substrate, and it is in the housing of a connector, The mounting part which pinches the above-mentioned substrate from board thickness is provided, and the above-mentioned connector attaching hole and a free passage To shake attachment hole are established in this mounting part, Between the connector terminal and the substrate terminal was electrically connected by the flexible substrate, and it carried out to coinciding the center of a connector, and the path-of-insertion center of an electronics package by carrying out free passage conclusion of the above-mentioned connector attaching hole and the attachment hole of a mounting part with a screw. For this reason, since the connector can be subject to insertion power at the center, it is lost, and can obtain Trustworthy connection. [ of a possibility of the curvature of a substrate being prevented, therefore causing aggravation of the Credibility of soldering of the mount part article by the curvature of a substrate and also the fall of a part function ] Since the connector is supported with floating structure, it becomes unnecessary to perform like before position Matching with the connector by the side of the device which is a front metallographic hand with high precision in the 2nd example. That is, both connectors only insert into a device the electronics package which has attached one connector, Since it was considered as the connector of another side, and the structure which can fit in, position Matching of both connectors had required the great man day, in order to have to carry out with high precision, however to unite this without error, when it fixed to a substrate and the main part of a device, respectively. In order to secure accuracy, the problem that the loading slot of a male connector had to be enlarged or the mounting pinch to the electronic device of a substrate had to be made large had also arisen, but it became possible by using floating structure to absorb the accuracy error between both. Thereby, since highly precise adjustment is not required of the attachment position of a connector, assembly nature becomes easy and the effect that fitting with a female connector can also be performed smoothly is acquired.
