Electronics device housing

The invention relates to a housing of an electronic device with two side wall elements spaced apart to form a housing with an interior for receiving at least one printed circuit board, at least one location being provided on at least one of the front sides in the space between the side wall elements. mounting on plug connectors for connecting wires.

[0002] Electronic equipment casings of different manufacturers of this type are known in various embodiments. In particular, they serve to ensure above all a universal system that can be adjusted by users to individual needs by properly selecting the available system components and equipping them with plug connectors and plug-in connectors. Thanks to this, it is possible to create in a simple and inexpensive way the housing of an electronic device from a universal system consisting of various system components, including side wall elements of an electronic device's enclosure.

[0003] EP 2 120 296 A1 discloses a casing for an electronic device with the possibility of being arranged in series for accommodating at least one printed circuit board with electronics, which on the one hand is provided with a socket-socket strip. This socket and pin strip is in contact with the terminal strip, which on one side is adapted for contact with external wires or a plug-in strip.

[0004] DE 10 2009 059 011 A1 discloses a connecting system for connecting a single-row housing to a connection element. A connection area is provided on the one-row housing for connecting the connection element to one single housing casing. The connection piece is fixed in the connection area by means of a plug-in connector. The plug-in connector may, for example, have the shape of a pin.

[0005] DE 10 2009 035 716 A1 further discloses a plug-in connector for connecting conductors to a casing made of insulating material and a clamping spring provided in a casing of insulating material. The housing of insulating material on one side is provided for placing a pin contact, and on the opposite side for placing an electric wire, the electric wire being pressed by the spring of the clamping spring to the pin contact and coming into contact with it directly or through a lying element therebetween sheet.

[0006] EP 1 513 385 A1 discloses a casing for an electronic device with two side wall elements spaced apart to form a casing with an interior for receiving at least one printed circuit board. At least one of the end faces in the space between the side wall elements is provided with a mounting place for a plug-in connector for connecting wires.

[0007] Based on this task, the present invention is to provide an improved enclosure of an electronic device that, with its simple construction, allows a flexible fit in the area of ​​the assembly locations of plug-in connectors for printed circuit boards.

[0008] This task is solved by means of a casing of an electronic device with the features of claim 1. Preferred embodiments are described in the dependent claims.

[0009] It is proposed that the housing of the electronic device in the area of ​​at least one mounting location has fixing assemblies that are adapted to be placed as desired

- tilting by means of a set device in the housing of the electronic device of the ejection element for ejecting a male connector for connecting the cable from the mounting location or

- latch permanently with retaining devices in the housing of the electronic device, a locking element for locking the plug-in connector to connect the wires at the mounting location.

[0010] According to the idea of ​​the present invention, retaining assemblies are provided in the mounting places on which an ejector element or a locking element can be provided at the choice. In the case of selecting the discharge element, the plug-in connector for connecting the wires is detachably mounted by tipping the ejection elements, whereas in the case of choosing a snap-fit ​​locking element, the plug-in connector for connecting the cable is locked in place at the mounting location. The contact of the plug connector for cable connection remains the same regardless of the connection.

[0011] The fixing assemblies at the mounting locations are now of such a nature that it is possible, at either choice, to pivot the ejection element or to securely engage the locking element.

[0012] This allows a simple insertion of a plug-in connector for the connection of a cable according to choice or with the possibility of being ejected or permanently locked, with only one set of accessories necessary including the expulsion means and locking elements for the housing of the electronic device.

[0013] It is particularly advantageous if the fixing units are further provided for selectively positioning, snap-shut by means of fixing units on the side wall elements, of a plug-in element to cover the free mounting space, not intended to receive a plug-in connector for connecting the conductor. Thanks to this, the kit can also comprise a third piece of equipment in the form of a plug-in element, which can be snap-fitted permanently on the housing of the electronic device similarly to the locking element. The blanking element may therefore have the same latch assemblies as the locking element and be latched in the same way on the electronics housing as the locking element. In contrast to the locking element, which only partially covers the plug-in connector to connect the cable for locking,

[0014] The fitting of the equipment elements at the mounting locations of the electronic device housing takes place in a very simple and reliable way, if in the area of ​​the assembly sites transversely to the side wall elements on a given face side, the two-way sections extend. These sectional baffles then have an exposed upper edge with a bearing groove to receive a bearing axis for selecting an ejection element, a locking element or a plug element. With a cross-sectional section extending transversely to the side wall elements, a stable support is formed for tilting or permanently latched placement of the piece of equipment, without causing excessive loading on the thinner, and therefore more flexible, side walls.

[0015] The sectional sections may advantageously be an integral part of the intermediate frame that forms the interior of the housing of the electronic device and is closed off the sides with side walls.

[0016] It is particularly advantageous if the openings of the bearing axis include openings for receiving the free ends of the bearing axis on the side wall elements in alignment with the bearing groove. The bearing axle therefore also passes through the side wall elements, which increases the stability of the support. In particular, the part of the equipment in the form of an ejection element, a locking element or a plug element is then not easily withdrawn from the bearing groove. In order to remove part of the equipment, it would be better to remove the bearing axle from the bearing groove and the openings in the side wall elements.

Alternatively to the bearing groove in the interspace portions in the lower region of the mounting locations on the individual side wall elements, mutually opposite pairs of openings can be provided for accommodating the free ends of a respective associated bearing axis of the ejection element, the locking element or the cap member. In this variant, the piece of equipment is deposited on the side wall elements by means of bearing axes inserted into openings in the side wall elements. These bearing axes can be, for example, cylindrical bearing bolts protruding on the sides. By means of bearing openings in the side wall elements, reliable support is also achieved without deforming the side walls to the outside. The support surface is reduced in practice to really short openings,

[0018] In the upper area of ​​the assembly sites, in a preferred embodiment, the side wall elements can receive claw-type plugs into the space between the two side wall elements. The latch pins are hereby provided, according to choice, to latch the hinged ejection element mounted in the casing of the electronic device, so that at least one protrusion of the pivot pin protruding from the side wall element engages in the latch opening of the ejection element. The protruding locking pins can also, however, be used to fix the locking element or blind element by providing in the locking element or plug element a perimeter-closed opening into which an associated latch pin is received. Protruding pins on the sides of the side wall elements and oppositely opposite snap-in pins can thus be used in the same way for snapping the swivel spout and for locking the locking element or plug element. The latching clip that fits into the latch pin must then only be provided on the ejection element for the releasable latch, while the fixed seating of the locking element or blind element is obtained through a hole extending so far over the circumference that the pivot point can not be led out from the hole outside the latching hole. .

[0019] In connection with the snap-in pinion or preferably alternatively to the snap-on journals on the side-wall elements in the upper area of ​​the mounting sites, openings may be provided in the side wall elements to receive snap-on lugs protruding on the sides of the ejecting element or on the sides of the locking element or closure element, or locking pins inserted through these openings from outside into side wall elements. In this embodiment, the tool elements therefore have snap-on lugs or locking pins (an ejection element, a locking element or a plug element) that cooperate with the openings in the side wall elements.

[0020] The latching of the swivel spout is manageable by the fact that the latch nose is guided into the associated hole by temporarily deforming the side wall member. The latching nose may for this purpose have e.g. an inclined insertion surface that allows locking and releasing to tilt the ejection element with a predetermined force.

[0021] Permanent snap, i.e. immobilization of the locking elements or plug elements, is achieved by means of locking pins which are inserted into the openings and which also can not be automatically released from the openings in the case of attempting to tilt the locking element or the plug element. The configuration of the snap-on lugs therefore causes a releasable locking, while the configuration of the locking pins causes permanent locking of the parts of the equipment.

[0022] This variant is relatively simple and inexpensive, however, it has the disadvantage that the lateral walls when the ejection element is tilted are temporarily deformed.

In the lower area of ​​the housing of the electronic device, preferably, a base plate is provided with a snap-on foot for snapping the housing of the electronic device on a support rail. This base plate can e.g. be an integral part of the intermediate frame, which is laterally covered by side wall elements and forms the interior of the housing of the electronic device.

[0024] Thanks to such a snap foot for the support rail, an electronic device housing is created that can be snap-fitted without a large amount of mounting on the support rail and arranged in series in other electronic device housings or serial terminals or other electrical devices.

[0025] In the upper area of ​​the housing of the electronic device, in a preferred embodiment, at least one curved retaining hole is provided for receiving an associated locking pin that protrudes from the cover element. By means of such a fixing hole on the curved connecting pin, it is possible to support the cover element on the housing of the electronic device in a tamper-proof manner. The locking pins in the retaining opening when tilting the element upwards from the housing of the electronic device constitute a stop which prevents the unauthorized removal of the cover element. In addition, such a fixing hole of the locking pin can also be used as a locking pin and as a support for the cover element and as a display element mounted on the housing of the electronic device.

[0026] It is particularly advantageous if contact supports with contact pins can be located at the bottom of the mounting locations at the choice. Then the contact pins with free end are set with one free end for contact with a printed circuit board placed inside the housing of the electronic device, and the other free end as counter-contact for the plug-in connector of the printed circuit board inserted into the installation location. Such a contact bracket with contact pins can be placed, if necessary, in the mounting locations where the plug-in connectors of the printed circuit boards must be inserted. Other, unpopulated mounting points can be covered with a blanking element. Such a contact bracket with contact pins has the advantage that the contact pins in the contact bracket are fixed and form a set with a contact bracket.

[0027] The contact bracket can also be used as a support for a piece of equipment (an ejector element, a locking element or a plug element).

The ejector element is preferably designed such that the ejection element in the vicinity of the bearing axis has at least one protruding finger. The at least one finger, when it is pivotably mounted to the units that fix the housing of the electronic device, then occurs from underneath by a plug-in connector of the printed circuit board inserted into the assigned mounting location, to be ejected from the assembly point by tipping the ejection element. The spout element thus has an L-shaped cross-section, the bearing axle being in the transition from the finger to the outgoing actuating arm.

The locking element is preferably designed such that at least one protruding flange is provided on the exposed upper edge. The flange is then adjusted so that when it is clicked into place on the housing of the electronic device, the flange includes a plug-in connector of the printed circuit board inserted into the assembly place and prevents it from being removed from the mounting location.

[0030] The locking of the plug-in connector of the printed circuit board in the inserted position is thus achieved by locking the locking element with the plug-in connector of the printed circuit board and thereby preventing it from being pulled out.

[0032] Figure 1 shows a perspective view of a housing 1 of an electronic device that has an invisible intermediate frame for creating an interior for placing electronics, e.g. a printed circuit board. The intermediate frame in the lower area has a base plate 2 with a snap foot 3 for a support rail that allows the electronic device casing to be snap-fitted into the support rail. In this way, a plurality of such housings and electronic devices can be placed side by side on the support rail in series.

[0033] The housing 1 of the electronic device is closed on its sides by means of side walls 4. The side walls separated away form an intermediate space on the front face side 5a and on the rear face side 5b for accommodating the plug connectors 6 for connecting the conduit. In this way, the housing 1 of the electronic device can be connected with plug-in connectors 6 for connecting wires with electric wires.

The upper side of the housing 1 of the electronic device is covered by a tilting cover 7, which is mounted on the swing bearing 8. In addition, a latching groove 9 for receiving the marking elements or the like is provided on the upper side of the housing 1 of the electronic device.

[0035] On the front and rear face sides 5a, 5b, on each of the three planes, mounting locations are provided that can be used to assemble the plug connectors 6 for connecting the wires. The casing 1 of the electronic device can, however, be individually folded up in front of the user, so that the mounting locations are optionally free and not provided with plug connectors 6 for connecting the wires.

[0036] In the event that the installation location 10 remains free and was not to be seated with a plug-in connector 6, the mounting location can be covered on the respective face 5a, 5b with a plug-in element 11. This plug-in element 11 is latched onto the housing 1 electronics and the assembled 1 electronics housing with the side walls 4 can not be simply removed.

[0037] In the event that the mounting location 10 was to be manned with a plug-in connector 6 for connecting the wires, the user has two options.

[0038] On the one hand, it is possible to permanently mount the male connector 6 for connecting the cable at the mounting location 10. For this purpose, a locking element 12 snaps-fitted permanently in the housing 1 of the electronic device is used. It is inserted into the housing 1 of the electronic device comparable to the blind element 11, after which it is not then easily detachable, but is fixedly fixed on the housing 1 of the electronic device. In this case, the locking element 12 on the upper side has a protruding flange 13, which is adapted such that the locking element 12 in the latching position shown in FIG. 1 at the installation site 10 on the housing 1 of the electronic device has a plug-in connector 6 for connecting the cable fully inserted into this mounting location 10 and received by the flange 13 and secured against removal from the assembly space 10. Alternatively or additionally, in addition to the flange 13, snap openings may also be provided, in which the projecting latch pins of the male connector 6 for connecting the conductor engage to lock it. It is clear that the plug-in connector 6 for connecting the cable can not, for example, be pulled up from the housing 1 of the electronic device by pulling the cable inserted into the plug-in connector 6 for connecting the cable. This is prevented by the collar 13, which includes a plug-in connector 6 for connecting the cable. pulled up from the housing 1 of the electronic device by pulling the wire inserted into the plug-in connector 6 for connecting the cable. This is prevented by the collar 13, which includes a plug-in connector 6 for connecting the cable. pulled up from the housing 1 of the electronic device by pulling the wire inserted into the plug-in connector 6 for connecting the cable. This is prevented by the collar 13, which includes a plug-in connector 6 for connecting the cable.

[0039] In this way, by means of the locking element 12, it is possible that the associated plug-in connector 6 for connecting the cable is also permanently mounted in the housing 1 of the electronic device. This is particularly beneficial in applications where touch protection is required due to hazardous voltages.

In practice, however, there is often a need for electrical wiring, e.g. when replacing a damaged electronic device, to be connected to a plug-in connector 6, and a plug-in connector 6 for connecting the wire during replacement can easily be inserted into a new housing 1 of the electronic device . For this purpose, it is advantageous if the plug-in connector 6 for connecting the wire can be easily connected to the casing 1 of the electronic device. For this purpose, discharge means 14 are provided, which can be placed tiltably on the housing 1 of the electronic device. This arrangement is advantageous in that a plug-in connector 6 for connecting a wire of the same construction can be used in both the use of the locking element 12 and the ejection element 14.

[0041] In figure 1 it can be seen that the ejection element 14 in the mounting location 10 at the top left of the front face 5a is tilted into the ejection position, i.e. open. Then, the plug-in connector 6 for connecting the wire is partially removed from the housing 1 of the electronic device.

[0042] On the side walls 4 in the intermediate space, on each of the front sides 5a, 5b there are provided two latching pegs 15, directed to the opposite side wall. These latch journals 15 are arranged in the mounting locations adjacent to any plug-in connectors 6 for connecting the wires, and are directed to the latch openings 16 in the ejection elements.

14. When tilting the discharge element 14 towards the plug-in connector 6 for connecting the conductor, the latch holes 16 are guided on the inner sides of the spout elements 14 with associated latch pins 15. In this way, the ejection element 14 latches into the latch plug 15 and on the walls in a closed position. side 4 casing 1 of the electronic device. The plug-in connector 6 for connecting the cable is fully inserted in the installation position 10. The latched thrust element 14 is held in this inserted position in the plug-in connector 6 for connecting the conductor. The protection of the plug-in connector 6 for connecting the cable on the housing 1 of the electronic device in the inserted position can be improved if the plug-in connector 6 for the connection of the conductor cooperates with the latching element 14,

[0043] For the electronic device, it is optionally important to provide air circulation in the housing 1 of the electronic device for cooling. For this purpose, it is advantageous if at least the plug elements 11 have ventilation slots 17. It is also possible that the locking elements 12 and / or the discharge elements 14 also have ventilation slots or at least in the area below the ejection element 14 and the locking element 12 are provided ventilation slots in the intermediate frame.

[0044] Figure 2 shows a perspective exploded view of the casing 1 of the electronic device of figure 1. It is clearly seen that in the interior of the housing 1 of the electronic device along the front sides 5a and respectively (invisible) opposite end face 5b extends the intermediate frame 18, on which the mounting locations are provided on three planes 10. The intermediate frame 18 is closed on both sides by the side walls 4, whereas in figure 2 only the left side frame is visible. Optionally, the side frame 18 and the side wall 4 can be formed as one piece.

[0045] In the mounting locations of these 10, 19 contact supports can be inserted. These 19 contact supports have contact pins 20, which on one side are designed to be connected to the circuit board in the housing 1 of the electronic device, and on the other hand for electrical contact with the plug-in connector 6 for connecting the conductor. It is clearly seen that in this embodiment each 19-pin bracket has four plug pins 20. In this way, each of the four plug connector cable connections 6 can be connected to the associated pin 20. The 19 pin brackets are particularly suitable for connection to the plug-in connector 6 for connecting the cable in the manner described in DE 10 2007 018 443 A1 and in DE 10 2009 035 716 A1, the contents of which are hereby referred to in full. Plug-in connectors 6 for connecting wires have here compression springs mounted in a housing made of insulating material (e.g., U-shaped clamping springs) that press the electric wire inserted into the hole 21 in the plug-in connector 6 towards the plug-in pin 20 coming into the plug-in connector 6 by electric wire. In this way, the electric wire is contacted directly or via a lying between the laminae. The plug-in connector 6 for the connection of the conductor is configured such that the electric cable can be inserted into the associated connecting hole 21 of the conductor without closing the plug hole via the electric cable to the associated pin 20. which presses the electric wire introduced into the opening 21 in the plug-in connector 6 towards the plug-in socket 20 which engages in the plug-in connector 6 next to the electric wire. In this way, the electric wire is contacted directly or via a lying between the laminae. The plug-in connector 6 for the connection of the conductor is configured such that the electric cable can be inserted into the associated connecting hole 21 of the conductor without closing the plug hole via the electric cable to the associated pin 20. which presses the electric wire introduced into the opening 21 in the plug-in connector 6 towards the plug-in socket 20 which engages in the plug-in connector 6 next to the electric wire. In this way, the electric wire is contacted directly or via a lying between the laminae. The plug-in connector 6 for the connection of the conductor is configured such that the electric cable can be inserted into the associated connecting hole 21 of the conductor without closing the plug hole via the electric cable to the associated pin 20.

[0046] The 19-pin brackets when fitting the consumer electronics housing to the user may be inserted into the installation location 10 at will.

[0047] The lower mounting location shown in figure 2 is not provided with a contact support, but is to remain free. To cover this vacant mounting space 10, a plug-like element 11 is provided, which has a L-shaped cross-section. In this way, the front side of the mounting location 10 is covered at the front and top respectively.

[0048] The housing 1 of the electronic device has, at the mounting points 10, transversal portions 4 to the respective end wall 5a, 5b transversely to the side wall elements 4 with the bearing groove 22 on the exposed top edge. In one line with this bearing groove 23, the side walls 4 may have openings 24 for receiving free ends on the bearing axis 25.

[0049] In this way, the parts of the equipment including the expulsion means 14, the locking elements 12 and the plug elements 11 can be supported essentially pivotably on the housing 1 of the electronic device. For this purpose, the individual parts of the equipment (discharge element 14, locking element 12 and plug element 11) have a bearing axis 25 at their lower edge, which can be inserted into the associated bearing groove 23. It is clearly visible that the bearing axles 25 of the accessory parts are longer than the width parts of the equipment and therefore protrude, so that the free ends enter the openings 24 of the side walls 4.

[0050] The bearing grooves 23 are preferably circularly shaped, so that the bearing axes 25 are inserted into the bearing grooves and held therein. The bearing slots 23 therefore comprise bearing axles 25 in a range greater than 180 °.

[0051] Furthermore, it can be seen that latch pins 15 project from the side walls 4. The ejector element 14 is now pivotably mounted in the mounting location 10, so that it is not permanently connected in the upper region with side walls or electronics housing. The one-sided open latching hole 16 is rather configured such that the latch pin 15 can be inserted into the associated latch hole 16. By applying sufficient force, the latch 26 engages the latch and the spout 14 is tilted relative to the bearing axis in the bearing groove. 23. In this case, the locking is released and the associated plug-in connector 6 for connecting the cable is removed from the mounting location 10.

[0052] The latch pins 15 can also be used to immobilally latch a piece of equipment in the housing 1 of the electronic device. For this purpose, openings 26 are provided on the locking element 12 and the plug element 11. When the locking element 12 or the plug element 11 is fixedly mounted in the mounting location 10, the associated latch 15 extends into the associated opening 26. This effectively prevents tilting the locking element 12 or the cap member 11. The locking element 12 or the cap element 11 is thus held in position.

[0053] Figure 3 shows a perspective exploded view on which the 19 contact pads are not yet inserted into the associated mounting location 10. Clearly, the mounting locations 10 have guides 10 or latch projections 27 on which the associated 19 contact pads can be attached to the frame. 18. The 19 contact supports can therefore be inserted from the side in the assembly place 18 and there led and fixed in the mounting position by means of the guide elements 27.

[0054] Furthermore, it can be seen that the intermediate frame has a large number of openings 28 for receiving matching snap pins of the side walls 4 so that the side walls are attached to the intermediate frame 18 and snapped onto it.

[0055] In this way, the housing 1 of the electronic device can be modularly assembled by the user as required.

[0056] Figure 4 shows a view of a casing 1 of the electronic device in the area of ​​the ejection element 14. It can be seen that the ejection element 14 has a L-shaped cross-section. In the vicinity of the bearing axis 25, a pair of protruding fingers are provided in the shown embodiment, which are arranged at a distance from each other on each side. From the long axis at an angle, preferably more or less perpendicular (70 ° -120 °), the actuating arm 30 extends, which extends approximately parallel to the inserted plug-in connector 6 for connecting the conductor.

[0057] It is clearly seen that in the inserted position shown in which the plug-in connector for connecting the conductor is fully seated on the associated contact support 19, the fingers 29 are arranged below the plug-in connector 6 for connecting the conductor. The fingers 29 then extend transversely to the direction S of inserting the male connector into the cable connection.

[0058] Furthermore, it can be seen that the free ends of the contact pins 20 are routed through the soldering holes 31 of the printed circuit board 82 so that they can be soldered to the printed circuit board 82.

[0059] It is clearly seen that the ejecting elements 14 in the upper area have a ribbed gripping surface 32 and an actuating hole 33. The ribbed gripping surface 32 facilitates manual tilting of the ejection element 14. The actuating hole 33 can be used to insert a screwdriver that serves as a tilting lever. the discharge element 14.

[0060] Figure 5 shows a view of the section of Figure 4 in the tilted removal position. It is clearly seen that the plug-in connector for connecting the conductor is deflected by tipping the finger 29 from the contact bracket 19 with its free end. By means of the tilting of the discharge element 14 and the fingers 29, it is possible to remove the plug-in connector 6 for connecting the cable in a predetermined manner upwards from the contact pins. The operation of the plug-in connector 6 for connecting the cable in the plug-in direction or in the opposite direction is provided by the side guiding wall 34 on the contact bracket 19. This guiding wall 34 is in the closed position according to figure 4 between the ejector element 14 and the male connector 6 for connecting the duct.

[0061] On the thrust element 14, the latch elements for engaging the male connector 6 for connecting the conductor in the closed position may, for example, have the form of latching holes 50, into which latch pins projecting from the plug-in connector 6 connect.

[0062] Figure 6 shows a perspective view of the ejection element 14. It is clearly seen that the two fingers 29 are arranged on both sides of the ejection element 14 in spacing from each other. The fingers 29 extend their free end parallel to each other and opposite the free end they extend into a transversely extending actuating arm 30. At the transition of the finger 29 and the actuating arm 30 below it, the bearing axis 25 is located on the strip 85 as a transition to the finger 29 and the actuating arm 30. It can be seen that on the bearing axis 25, projecting snap-on noses 35 are provided on each of the two outer regions. These snap-action noses in the open position shown in figures 5 and 9 engage in matching recesses 38 in the bearing groove 23. This allows the ejection element 14 is kept in a defined open position. In the closed position according to figure 4 and figure 8, the noses 35 snap onto the underlying bearing protrusion 23 adjacent the cavity 38 to engage the ejection element 14 in a defined closed position. Therefore, the tilting of the discharge element 14 requires the application of a certain force to overcome the limiter acting on the noses 35.

[0063] Furthermore, it can be clearly seen in figure 6 that a latch slot 36 for receiving the descriptive elements is provided on the upper side of the ejector element 14. These descriptive elements can then be attached to the latch groove 36 and held therein.

[0064] Figure 7 shows a perspective view of the ejection element 14 according to figure 6 on the other side (rear side). It is clearly visible in the latch groove 36 that descriptive elements 37 are provided. Four descriptive elements 37 are provided separately or connected to each predetermined breaking point, and one descriptive element is provided for each hole for the introduction of the 4-pole connector connector. 37.

[0065] Figure 8 shows a view of a portion of the ejecting element 14 inserted in the bearing groove 23 with the bearing axis 25 in the closed position according to figure 4. It is clearly seen that the protruding nose 35 on the bearing axis 25 together with the projection 39 limiting the recess 38 in the bearing groove 23 is a stop that holds the ejection element 14 in the closed position. In order to tilt the discharge element 14 in this view, counter-clockwise, this stop must be overcome. A certain amount of force or sufficient torque is required for this.

[0066] When the ejection element is tilted into the open position according to figures 5 and 9, the protruding nose 35 of the bearing axis 25 enters the recess 38 of the bearing groove 23. In this way, the ejector element 14 rests in this predetermined open position.

[0067] Figure 10 shows a section view of a further embodiment of the ejecting element 14. This ejector element 14 has an L-shape with at least one finger 29 and an upwardly extending actuating arm 30 and a lower bearing axis 25. The bearing axle 25 is of in turn, bulged forward and inserted or latched in the latch groove 23. In cross-section it has a circular sector shape and is comparable to the circular rod of the previously described bearing axis 25 with the difference that a nose 40 projects from the bearing axis 25. Bearing groove 23 for recess 41 or a recess adapted to the nose 40, in which the nose 40 may enter in the ejection position of the ejection unit 14 again. This is outlined in Figure 11, which shows the discharge assembly 14 in the open position in accordance with Figure 5.

[0068] In this way, the nose 40 and the wall restricting the recesses 41 form a stop that prevents or at least obstructs undesired balancing of the ejection unit 14. Further tilting of the ejection unit 14 outside the open position shown in figure 11 is prevented by the nose 41.

[0069] The nosepiece 40 and the matching cavity 41 may extend over the entire width of the bearing axis 25 and / or the bearing groove 23. It is also possible, as in the case of the nose pieces 35 in the previous embodiment (see figure 6), that only a limited number is provided. 1, 2, 3, 4 or more noses 40 that are spaced apart. In this context, it is possible that the recess 41 or cavity extends over the entire length of the bearing groove 23, or in the bearing groove 23 individual recesses 41 adapted to the individual nose pieces 40 are made.

[0070]

The noses 40 are integrally formed with the bearing axis 25, preferably plastic.

[0071] Figure 12 shows a perspective view of a contact bracket 19 that is molded from an insulating material (especially plastic). The contact support 19 has fixed contact pins 20, which are e.g. arranged in a row next to each other and extend parallel to one another in the plug-in direction. The plug pins 20 thus have a correspondingly rectilinear contact section which protrudes upwards from the platform 42 of the contact bracket 19 by its free end. It is clearly seen that the rectilinear contact section is surrounded by the insulating material of the contact bracket 19 and in this immobilization area is fixed to the contact bracket 19. The contact pins 20 are held stably on the platform in the immobilization area, in that they are preferably covered by an insulating material at a circumference greater than 180 °,

[0072] Furthermore, it is clearly seen that the contact pins 20 are bent below the platform 42, so that the free ends of the contact pins 20 project from the sides of the contact bracket 20 for connection to the printed circuit board 82. The direction of extension of these free ends is perpendicular to the direction of straight extension. of the contact sections and parallel to the alignment direction of the contact pins 20 arranged in a row next to each other.

[0073] Furthermore, it is seen that the bent contact pins 20 are arranged side by side such that the free ends to be connected to the printed circuit board 82 are run side by side without collision and retain the required air sections and creep sections, and protrude from the sides of the support 19 contact. In this way, a printed circuit board 82 can be connected on the side to the contact bracket 19, which has openings for receiving free ends and their soldering to the circuit board 82.

The circuit board 82 would then extend in a plane that is defined on the one hand by the direction of the straight contact sections of the contact pins 20, and on the other side by the direction perpendicular to the rectilinear contact section and free ends for connection to the circuit board 82.

Furthermore, it can be seen that the free ends for connection to the printed circuit board 82 rest on at least one supporting area 43 on the associated supporting plinth 44. The support plinths 44 can e.g. be formed on the separating strip of the contact bracket 19. The support plinth 44 can be, for example, a circle-shaped recess into which a given contact pin 20 is inserted from the bottom towards the platform 42. On the opposite side to the platform 42, the contact pin is freely accessible in the support region, so that the contact pins 20 they can be inserted from below into the contact support contact 42 and pressed or possibly caulked in the contact bracket 19.

Furthermore, it can be seen that on the back side of the contact bracket 19, it is integrally formed with the contact bracket 19 adjacent to the platform 42, the guiding wall 34. The guide wall 34 extends parallel to the straight contact sections and forms a plane that is parallel to the rectilinear sections contact pin pins arranged in a row next to each other.

[0077] Between the straight contact portions of the contact pins 20 and the guide wall there is a hollow space such that the plug connector 6 for connecting the wire can be plugged onto the contact pins 20, adhering to the guide wall 34 with a clamping contact with spring force. The guide wall 34 can be optimally adapted to accommodate the coding elements that serve to insert only the approved plug connectors 6 for connecting the cable with an approved orientation.

[0078] Figure 13 shows a perspective view of the housing 1 of the electronic device in a slightly different set-up. It can be seen that on the right front side 5b a plug element 11 is inserted into the upper mounting place 10. In the downstream assembly place, an ejection element 14 is provided for releasably inserting the male connector 6 for connecting the conductor. On the lower plane there is a locking element 12 for a permanently locked position of the plug-in connector 6 for connecting the cable.

[0079] On the left front side, on the lower mounting location 10, i.e. on the lowest level, there is a blind element 11. Above it is provided a locking element 12 for permanently locking the position of the male connector 6 for connecting the conduit.

[0080] At the upper mounting location 10, however, a tilting outflow element 14 is provided for detachably accommodating a male connector 6 for connecting the conduit.

[0081] As a result, it can clearly be seen that the individual mounting locations 10 can be equipped with expulsion means 14, locking elements 12 or plug elements 11, as desired, thus the mounting locations can be freely equipped with plug-in connectors 6 for connecting wires or not provided in not for cap elements 11.

[0082] Figure 14 shows a perspective view of a sector cutout 1 of an electronic device in the region of a connector 6 for connecting a wire which is arranged tilt 14 separately at the mounting location 10. It is clearly visible that the plug connector has four holes placed next to one another. 21 for inserting the conductor and for each opening the actuation button 45 for opening placed inside the clamping spring and releasing the electric conductor.

[0083] It can be seen that each aperture for inserting the conduit is assigned a descriptive element 37. The descriptive elements 37 are connected to a latch slot 36 on the upper side of the spout 14.

[0084] Figure 15 shows a corresponding view with a locking element 12. It can be seen that a snap-in groove 36 is provided on the flange 13, which includes a male connector 16 to secure the cable at the mounting location 10. each entry 21 for inserting the conductor is in turn connected with one descriptive element 37.

FIG. 16 shows a perspective view of a sector of the electronic housing 1 in the region of the cover member 7. It is evident that a curved locking pin 46 is formed below the hinged bearing 7 on the cover element, which in the shown closed position enters the fixing hole 37 of the locking pin. . By means of this locking pin 46, the cover 7 is protected against unauthorized lifting upwards. The locking pin 46 then forms, together with the fixing opening 47, a locking pin limiter.

[0086]

To secure and seal the cover element on the housing 1 of the electronic device, a material wing 48 with an opening 49 is provided on the front free end of the cover element (see figure 17). When the lid member 7 is in the closed position, the holes 49 and 51 are in line with the openings 49, 51, and the lid 50 may be inserted into the housing of the electronic device. securing or a security wire for sealing, or possibly a padlock. In this way, the cover element 7 is mounted on the housing 1 of the electronic device by means of locking pins 46 in a tamper-proof manner.

[0087] The cover element 7 is furthermore secured in that a protrusion is protruded from the material flap 48 leading to the formation of the guide groove 53. When tilting the cover element 7 downwards, the ear 50 comes partly into this guide groove 53. With a nose The guide 52 prevents the cover element from sliding sideways.

[0088] Below, the guide nose 52 projects a latching lug 54 that latches onto the ear 50 and secures the cover member 7 in a closed position on the casing 1 of the electronic device.
