Abstract

La présente invention concerne un dispositif de contact pour établir un contact électrique entre les bases (4) de la fiche d'un composant électrique (1) et les alvéoles formées dans un autre composant électrique (5). Afin de pouvoir introduire sans forcer les bases (4) de la fiche dans les alvéoles correspondantes (6), le diamètre de ces dernières est plus grand que le diamètre externe des bases correspondantes (4) de la fiche. Pour établir ledit contact électrique, on rapproche les deux composants électriques (1 et 5) l'un vers l'autre de manière sensiblement perpendiculaire à l'orientation des bases (4) de la fiche, puis on arrête le déplacement, de sorte que les bases (4) de la fiche sont déviées de côté et se retrouvent prises entre le bord interne supérieur et le bord interne inférieur des alvéoles (6).The present invention relates to a contact device for establishing electrical contact between the bases (4) of the plug of an electrical component (1) and the cells formed in another electrical component (5). In order to be able to introduce without forcing the bases (4) of the plug into the corresponding cells (6), the diameter of the latter is greater than the external diameter of the corresponding bases (4) of the plug. To establish said electrical contact, the two electrical components (1 and 5) are brought closer to each other in a manner substantially perpendicular to the orientation of the bases (4) of the plug, then the movement is stopped, so that the bases (4) of the plug are deflected to the side and are caught between the upper internal edge and the lower internal edge of the cells (6).

Description

Plug contact arrangement

The invention relates to a plug contact arrangement of the type mentioned in the preamble of claim 1 and claim 12.

5 In modern electronic devices, there is often the task of electrically contacting components provided with plug feet with other components which have contact bores for receiving the plug feet. To ensure a safe contact, the

10 contact feet are generally soldered in the contact holes. This process is very complex and expensive. In addition, it has the disadvantage that the plugged-in components can no longer be removed or replaced, or only after the soldered connection has been destroyed. Around

^{In order} to facilitate the replacement of components to be plugged in, it is also common to first plug bases on the components having the contact bores, the feet of which are soldered to the contact bores. The bases have plug sockets into which the

"-" O contact feet of the components to be plugged in. In order to ensure reliable contact here, the plug sockets generally have resilient contact surfaces on the plug feet. This is why large connectors are required, especially for components with many plug feet.

2 ⁵ forces to overcome when coupling or uncoupling, which often leads to damage to such components. Another application in which conventional contact arrangements are unsatisfactory, DAS * ^'' area of the test adapter for testing printed circuit boards. The circuit boards to be tested generally have a very high density of conductor tracks and components, so that the number of test points is very large. In the test adapters, an adapter plate must be fitted with test pins to match the test points on the printed circuit board, which are in turn connected to the test circuit. In conventional WRAP technology, cables are soldered to the lower ends of the test needles, which lead to the test circuit. Setting up such test adapters is extremely lengthy and, because of the confusion of the large number of cables to be handled, leads to errors that are difficult to detect and to remedy.

Another area of application in which conventional contact arrangements no longer lead to satisfactory results is the contacting of a plurality of circuit boards which are parallel to one another. This is generally done via so-called wiring back panels, on which these circuit boards are plugged and which contains the connection circuit for connecting the circuit boards.

It is the object of the present invention to provide a contact arrangement of the type mentioned in the preamble of claim 1 and claim 12, which is simple, ensures reliable contact and is also easily detachable. This object is achieved according to the invention by a contact arrangement having the features described in claim 1 or the features described in claim 12. The contact arrangements according to the invention are so-called force-free plug-in connections, since the contact bores each have a clear width which is larger than the outer dimensions of the plug feet or contact wires to be received by these contact bores. These can therefore be inserted into the contact holes without any effort. Only after the plug-in process are the terminals of the connector feet or the contact wires clamped in the contact sockets, so that on the one hand a secure hold and on the other hand a reliable contacting of the connector feet or contact wires is given in the associated contact bores. To release the contact arrangement, the contact bores are again aligned so that there is no longer any deflection of the plug feet or contact wires transverse to their longitudinal alignment, so that the contact arrangement can in turn be released without force.

Further features and advantages of the invention result from the patent claims, from the exemplary embodiments shown in the drawing and from the description relating to them. Show it:

Figure 1 shows a flat cable connector 1, which is divisible in a division line 2 and in which a flat cable 3 can be inserted in a known manner; when the two parts of the flat cable connector 1 are assembled, the connector feet 4 are contacted by the self-tapping contacts with the wires of the flat cable 3.

The circuit board 5 is provided with contact holes 6, which serve to receive the plug feet 4. The inner surfaces of the contact bores 6 are each galvanically provided with conductive material (so-called vias), which are connected to conductor tracks (not shown here) on the surface of the printed circuit board 5.

The flat cable connector 1 is provided with latching elements 8 which protrude through latching bores 9 in the printed circuit board 5 and engage behind them on the underside of the printed circuit board 5. As can be seen in Figure 1, the locking elements 8 are approximately mushroom-shaped. To mount the flat cable connector 1, the heads of the mushroom-shaped locking elements are aligned with the bores 9 so that they can pass through them. With this orientation, the plug feet 4 are also aligned with the contact bores 6. The contact holes 6 have a clear width that is larger than the outer dimensions of the plug feet 4. The flat cable connector 1 can therefore be plugged onto the circuit board 5 without any forces. After plugging in, the flat cable connector 1 is in the direction of arrow 10 essentially displaced transversely to the longitudinal orientation of the plug feet 4, the heads of the mushroom-shaped locking elements 8 engaging behind the locking bores 9 (see FIG. 1). The plug feet 4 are deflected laterally and tilted in the contact holes 6 so that they come into contact with the upper or lower inner edge of the contact holes 6.

In order to lock the flat cable connector 1 in the assembled position shown in FIG. 1, at least one of the feet 11 of the flat cable connector is provided on its underside with a projection 12 which, when the flat cable connector 1 is displaced in the direction of arrow 10, behind one on the upper side of the printed circuit board 5 protrusion 13 engages, as can be seen in FIG. 2, which shows detail A from FIG. 1 in an enlarged illustration.

FIG. 3 again shows a flat cable plug 15 with plug feet 16 which engage in contact bores 17 in a printed circuit board 18. The flat cable connector 15 is connected in a manner not specified to a component 19, for example a device wall. To insert the flat cable connector 15 into the contact bores 17 of the printed circuit board 18, the flat cable connector 15 is aligned so that the plug feet 16 are exactly aligned with the contact bores 17. After insertion, the component 19 and the printed circuit board 18 are displaced relative to one another transversely to the longitudinal orientation of the plug feet 16, the plug feet 16 being laterally deflected and tilted in the contact bores 17 such that they are in each case between the upper and lower inner edge of the associated contact hole 17 are clamped, whereby on the one hand the contact with the contact bores 17 or the metallic inner surfaces lining them 20 and on the other hand the firm mechanical hold in these vias 20 is ensured. * - '

FIG. 4 shows an arrangement with two circuit boards 22, 23 parallel to one another. An electrical component 25, for example a memory module, provided with plug feet 24 is mounted on the circuit board 22 in a manner similar to that described with reference to FIG. The component 25 is first aligned with the printed circuit board 22 so that the plug feet 24 are aligned with the contact bores 26. After the force-free insertion, the component 25 is moved in the direction of the arrow 27, the connector feet 24 contacting the contact bores 26 in the manner already described. In the same way, an electrical component 28, for example a computer module, is mounted on the printed circuit board 23, the plug feet 29 of the component 28 contacting the contact bores 30 of the printed circuit board 23.

In order to contact the circuit boards 22 and 23 with one another, a further component 31 is arranged between these circuit boards 22, 23, which has the shape of a plate parallel to the circuit boards 22, 23. This component carries contact feet 32 which engage on the one hand in contact bores 26a of the printed circuit board 22 and on the other hand in contact bores 30a of the printed circuit board 23. For this purpose, component 31 is first aligned such that the plug feet are exactly aligned with the associated contact bores 26a and 30a. After the plug feet 32 have been inserted into the associated contact bores, the component is moved in the direction of the arrow 33, the plug feet 32 being securely contacted in the manner already described with the associated contact bores 26a, 30a. FIG. 5 shows an arrangement similar to FIG. 4 with two printed circuit boards 34, 35, each of which carries an electrical component 36 or 37, which are connected to the printed circuit boards in the manner described with reference to FIG. To contact the two printed circuit boards 34, 35 with one another, a plate-shaped component 38 is provided between them. This is provided with bores 41 which are arranged in the same pattern as the contact bores 39 of the printed circuit board 34 and the contact bores 40 of the printed circuit board 35. In order to contact the printed circuit boards 34, 35 with one another, these and the component 38 are aligned with one another in such a way that that the contact bores 39, 40 and the bores 41 are aligned with one another. Then contact wires 42 are inserted through these aligned bores and component 38 is displaced, for example, in the direction of arrow 43, whereby contact wires 42 are laterally deflected and respectively tilted in the associated contact bores 39 and 40 so that in the an electrical contact and a mechanical fixation can be produced.

FIG. 6 shows a contact arrangement for contacting perpendicular printed circuit boards. The circuit board 45 serves, for example, as a so-called wiring rear wall, to which the circuit boards 46, 47 are perpendicular. A component 49 provided with plug feet 48 is connected to the printed circuit board 46 in the manner already described with reference to FIG. 1, the plug feet 48 being contacted with the contact bores 50 of the printed circuit board 46. The plug feet 48 are connected to these plug feet 51, which are approximately at right angles and which in turn engage in contact bores 52 in the printed circuit board 45. Contacting the plug feet 48 with the contact holes 50 of the printed circuit board 46 takes place by moving the component 49 in the direction of the arrow 53, in the manner already described with reference to FIG. 1 and not shown again in detail here. The contacting of the plug feet 51 with the contact bores 52 takes place by displacing the printed circuit board 45 in the direction of the arrow 54. In a similar way, the printed circuit board 47 is connected to the printed circuit board 45 via the component 55 with the plug feet 56 and 57.

FIG. 7 shows detail B from FIG. 6 in an enlarged representation. It can be seen that the contact foot 56 is tilted by its deflection transversely to its longitudinal orientation in the contact bore 58 such that it has an upper inner edge 59 and a lower inner edge 60 of the metal-lined through-contact 61 of the contact bore 58 comes into intensive contact, so that on the one hand an electrical contact is made and on the other hand mechanical hold of the plug base 56 in the contact bore 58 is guaranteed. As particularly shown in FIG. 6, the plated-through holes are each connected to conductor tracks formed on the printed circuit boards, as is known and is therefore not explained in detail.

FIG. 8 shows a contact arrangement which is used in particular to connect the test pins 63 of a test adapter 64 to a test circuit (not shown). Test adapters for testing printed circuit boards generally have the following structure: Test pins 63 are fixedly arranged in a predetermined pattern in a mounting plate 65, the resilient test tips 66 pointing upward. Above the mounting plate 65 there is a support plate 67 on which the circuit board to be tested with the test points to be contacted is placed down. The support plate 67 with the printed circuit board arranged thereon can be moved downward against the force of the spring 68, the test points resting on the test probes 66.

The lower ends of the test pins 63 carry plug feet or contact wires 69 which, in the present exemplary embodiment, pass through contact bores 70, 71, 72, which are aligned with one another, of the printed circuit boards 73, 74, 75 arranged parallel to one another. The middle printed circuit board 74 is mounted in the test adapter 64 so as to be displaceable in the direction of the double arrow 76. To contact the printed circuit boards 73, 74, 75 with one another, the contact wires 69 of the test pins 63 are inserted through the associated contact bores 70, 71, 72 of the printed circuit boards 73, 74, 75. Since the clear widths of these contact bores are larger than the outer dimensions of the contact wires 69, this plug-in process takes place without force. After the contact wires 69 have been plugged in, the printed circuit board 74 is displaced to the left in the manner shown in FIG. 9 relative to the printed circuit boards 73 and 75 in the direction of the arrow 77, as a result of which the contact wires 69 are deflected laterally. As a result, they are tilted in the associated contact bores 70, 71, 72, so that electrical contact is made with the contact bores in the manner already described.

By increasing the number of printed circuit boards, the number of contacts of the individual test pins 63 can largely be increased as desired.

The middle printed circuit board 74 is displaced, for example, by one perpendicular to the plane the axis of rotation 77 of the printed circuit boards rotatable eccentric cam 78 which engages in an elongated hole 79 in the printed circuit board 74 which is aligned transversely to the displacement direction 76. The eccentric cam 78 is adjusted, for example, manually using a handle 80 which is connected to the shaft 81 which carries the eccentric cam 78.

The contact bores 70, 71, 72 are each connected to conductor tracks 82, 83, 84 arranged on the associated printed circuit boards 73, 74, 75, which lead to plug connectors 85 arranged on the edge of the printed circuit boards, via which a connection to the test circuit is possible.

FIG. 10 shows schematically the middle printed circuit board 74 from FIGS. 8 and 9. The eccentric cam 78 is adjustable on a circular path 86 and takes the printed circuit board 74 along in the direction of the double arrow 76. The circuit board 74 is guided exactly parallel through elongated holes 87 aligned parallel to the double arrow 76, through which vertical connecting struts 88 of the test adapter 64 pass (see also FIG. 8).

FIG. 11 shows an exemplary embodiment in which a printed circuit board 74a is adjustable on a circular path lying in its plane. Two circular eccentric cams 89, 90 are each synchronously adjustable on circular paths 91, 92. You take the circuit board 74a with it so that it moves according to the double arrow 93. The connecting struts 88a reach through circular guide holes 87a in the printed circuit board 74a and contribute to the correct guidance of the printed circuit board 74a. FIG. 12 shows a contact arrangement in which three circuit boards 95, 96, 97 arranged in parallel to one another are to be contacted. They are provided with contact bores 98, 99, 100 which are aligned with one another and through which a contact wire 101 is inserted, which is straight during this insertion process. The contact bores 98, 99, 100 have an internal width which is larger than the outer dimensions of the contact wires 101, so that the contact wires 101 are inserted without force. Devices 102, 103 for lateral deflection of the contact wires 101 are arranged between the printed circuit boards 95 and 96 on the one hand and 96 and 97 on the other hand. The devices 102, 103 have the form of flat plates which are provided with through bores 104 and 105, respectively, which are distributed in an arrangement pattern corresponding to the arrangement pattern of the contact bores of the printed circuit boards 95, 96, 97. To contact the circuit boards with one another, the device 102 is moved in the direction of the arrow 106 and the device 103 in the direction of the arrow 107, as a result of which the contact wire 101 is laterally deflected in the manner shown in FIG. 12 and thus tilted in the associated contact holes 98, 99, 100 is that an electrical contact is made in the manner already described. In the exemplary embodiment shown, the contact wires 101 are fastened to a holding plate 108, in which their ends are inserted into blind bores 109 and soldered therein. The holding plate 108 itself can be designed as a printed circuit board, as indicated by the conductor track 110 arranged thereon.

The contacting of a plurality of circuit boards 95, 96, 97 which are parallel to one another in accordance with the exemplary embodiment shown in FIG. 12 can take the place of Common arrangement occur in which the circuit boards are plugged onto a common wiring rear wall. In this conventional arrangement, there are comparatively long connection paths between components which are arranged on different printed circuit boards, since the conductor tracks are always led to plug connectors arranged at the edge of the printed circuit boards and over the common wiring rear wall. In contrast, with the arrangement according to FIG. 12, a much more direct and shorter connection between components of different circuit boards is possible.

FIG. 13 and FIG. 14 each show a cross section through a plug base or a contact wire, for example the contact wire 101 from FIG. 12. In order to improve contact with the associated contact bores or the bushings lining them, the contact wires each have one polygonal cross section with sharp cutting edges 111 and 112 running along surface lines. The contact wires are advantageously made of spring steel and are gold-plated.

FIG. 15 shows an arrangement roughly according to FIG. 5, in which a circuit board 200 to be tested is to be contacted, for example, with a first contact plate 201 and a second contact plate 202. The circuit board to be tested is equipped with electronic components 203. The printed circuit board 200 to be tested has contact holes 204, the first contact plate 201 has contact holes 205 and the second contact plate 202 has contact holes 206, which can each be aligned with the contact holes of the other plates. Contact wires 207 are threaded into these contact bores 204, 205 and 206. In order to facilitate the threading of the contact wires 207, for example A guide plate 208 is arranged between the printed circuit board 200 and the first contact plate 202 and is provided with guide bores 209 arranged in the grid of the contact bores of the printed circuit board 200 and the first contact plate 201. It can be seen that the contact bores 209 are designed downwards as funnel-shaped catch bores in order to facilitate catching the contact wires 207 during the threading process. The guide plate 208 can be moved up and down in the direction of the arrow 210 and can be locked at least in its lower and upper position.

FIG. 16 shows a threading process for the purpose of testing a printed circuit board 200. The guide plate 208 is shown in its upper position in FIG. 16A. The funnel-shaped guide bores 209 allow the contact wires 207 to be threaded even in the event of a slight misalignment of these contact wires. The printed circuit board 200 is placed on the guide plate 208 and precisely aligned to it on the one hand and the printed circuit board on the other hand, so that the contact bores 204 of the printed circuit board 200 are exactly aligned with the guide bores 209 of the guide plate 208 (see Fig. 16B). Then the guide plate 208 is lowered, so that the circuit board 200 can also be moved into a somewhat lowered test position, in which the contact wires 207 completely penetrate the contact holes 204. Then, by mutual transverse adjustment of the contact plate 201 to the printed circuit board 200 in the manner described above, a contact can be made, the guide bores 209 of the completely lowered guide plate 208 not obstructing an inclined position of the contact wires 207, in particular to the printed circuit board 200. 17 shows an electronic component 301 provided with plug feet 300. The component 301 is provided with a rectangular flange 302 which can be inserted into a receiving groove 303 of a receiving housing 304 assigned to the component 301. The receptacle housing 304 has a base plate 305 which is provided with through bores 306 which are widened in a funnel shape for the passage of the plug feet 300.

A cam 308 is formed on the rectangular flange 302 of the component 301 on a side edge 307, as the top view in FIG. 17A of the component 301 shows in particular. When the component 301 is inserted, the cam 308 lies in a recess 309 in the side edge of the receiving housing 304 assigned to the side edge 307 and extends into a channel 310 running parallel to the side edge 307, in which a channel provided with a cam curve 311 Sliding lock 312 is slidably arranged (see also Fig. 18). To assemble the component 301, the receptacle housing 304 is first placed on a printed circuit board 313 and aligned and fastened thereon by means of centering pins 314. The component 301 is then inserted into the receiving housing 304 from above, the connector feet 300 being threaded into the contact bores 315 of the printed circuit board 313 via the through-bore 306 designed as a collecting funnel. There is essentially no plug-in force to be used when plugging in, since the plug feet 300 sit with play in the contact bores 315. In the position shown in FIG. 19, the cam 308 lies in the recess of the slide latch 312 defined by the cam curve 311. When the slide latch 312 is moved in the direction of the arrow 316 (see FIG. 18), the component 301 Moved to the left in the manner shown in Fig. 20, the connector feet 300 bent and tilted in the contact holes 315 of the circuit board 313, so that there is contact. The length of the plug feet 300 is, for example, ten times the depth of the contact holes 315, so that the force applied to them in the upper area of the plug feet 300 is increased to a ten times greater contact force in the area of the contact holes due to the leverage effect .

FIG. 21 shows the arrangement according to FIG. 19 in a top view.

22 and 23 show an exemplary embodiment for connecting a first printed circuit board 400 to a second printed circuit board 401 which is at right angles thereto. For this purpose, a contact arrangement 402 is used, which consists of a component 404 provided with plug feet 403 and a receptacle housing 405. The component 404, which is connected in a suitable manner to the printed circuit board 400 and the circuit elements arranged thereon, is used for contacting in the component 405 connected to the printed circuit board 401, the plug feet 403 via the funnel-shaped through-bores formed in the base plate 406 of the receptacle housing 405 407 caught and threaded into the contact bores 408 of the circuit board 401. The component 404 can be displaced, for example, by hand relative to the receiving housing 405 in the direction of the arrow 409 and can be locked with the latter by a latching element 410. An actuating tab 411 serves to release the latching element 410.

As shown in FIG. 23 in particular, the plug feet 403 are again deflected and with the contact bores

408 contacted the circuit board 401, wherein by the compared to the depth of the contact bores 408, the large length of the plug feet 403, an increase in force is achieved, as has already been described with reference to the previous exemplary embodiment.

It should be mentioned that the upper component 404 can also be designed, for example, as a housing for receiving a ribbon cable, so that a construction corresponding to the construction shown in FIGS. 22 and 23 can also be used to connect flat cables to cables terplatten is usable.

24 and 25 show a circular plug arrangement with a plug 500 and a socket 501. The plug housing 502 has at its lower end an axial ring flange 503, into which an insert 504 for holding the plug feet 505 is inserted on the inside. An adjustment ring 506 is rotatably mounted on the axial ring flange 503, the inner contour of which is eccentric to the outer contour in the upper region mounted on the ring flange. In addition, an axially displaceable insert 510 is arranged in the plug housing, which is pressed axially outwards by a compression spring 512 and corresponds approximately to the receptacle housing of the preceding exemplary embodiments. It has a base 516 provided with funnel-shaped catch bores 514.

The socket housing 507 has an insert 508 at its front end, which has contact sockets 509 for receiving the plug feet 505. When the plug 500 is coupled to the socket 501, the insert 510 penetrates the insert 508 and is pressed inward against the force of the spring 512, so that the plug feet 505 enter the contact sockets 509. By turning the adjusting ring 506 with respect to the plug housing 502 and socket housing 507, which is held against rotation, the entire socket 501 is laterally displaced in the direction of the arrow 510 with respect to the plug 500, so that the plug feet 505 are deflected and tilted in the socket openings 509 and thus tilted be contacted. The ratio of the length of the plug feet 505 to the penetration depth of the plug feet 505 in the contact bores 509 in turn determines the amplification of the adjusting force applied to a contact force that is substantially greater in comparison.
