Definitions

  • the invention relates to an actuating device for positioning an object from an undefined starting position into a starting or reference position characterized by a resistance to the actuating movement and from this by a predetermined distance into a defined end position, in particular for the relative setting of electronic circuit modules for inserting the plug pins of the Module in the assigned contact sockets of a socket base or vice versa.
  • the invention is preferably intended for use in testing and in the assembly or disassembly of electronic circuit components, so-called modules.
  • modules are provided with a large number of contact pins which are inserted into sockets with sockets of an appropriate arrangement.
  • the number of external connections i.e. the Connector pins
  • the insertion of the pins into a socket or a socket strip on a printed circuit board is a difficult task, since additional forces are required to insert a large number of pins into corresponding friction bushings, in particular because the pins are not exactly the same length and Arrangement of the sockets relative to the pins is not completely identical.
  • plug connections of this type that the often very small contact pins establish a safe and reliable electrical contact connection with the associated plug sockets.
  • the production of such plug connections requires different forces during the insertion process, as is shown graphically in FIG. 1 of the accompanying drawings.
  • area A shows, only a very small force is to be exerted from a starting position when the pins approach until the contact with the contact surfaces begins. Now the required force rises sharply due to the spreading of the contact springs, as can be seen in region B in FIG. 1. If the spreading force for the pins, at least for most of the pins, is applied, the further insertion force is reduced and then remains constant, as the area C shows. The end of the maximum possible path is now reached at the beginning of area D.
  • US Pat. No. 3,784,954 shows a solution in which a circuit module or a printed circuit board has bolt-like elements which have a precise position relative to the pin ends, and for inserting or removing the modules, actuating arms which are pivotably mounted on the frame are provided with the bolt elements interacting actuating cams used.
  • precisely positioned pin elements are attached to the module, which interact with actuating pins on an assigned rocker arm.
  • such measures cause higher module costs and also undesirably limit the space on the substrate that is available for the circuit elements and the contact pins.
  • the invention has for its object to provide a device with which without special requirements for the dimensional accuracy of the workpiece and its individual parts, such as. B. the pins of modules of the intended type, a travel of a defined length can be achieved without the starting position being known or must be defined.
  • starting position is the position from which the actuating movement begins
  • starting position is the position whose position is not exactly known or can vary from case to case and at which the desired movement of predetermined length begins.
  • the adjusting device according to the invention is characterized by a simple structure, requires no special elements on the object to be adjusted and furthermore does not impose any specific requirements on its dimensional accuracy.
  • a preferred application of the invention is seen in the insertion of circuit modules with a large number of contact pins into corresponding sockets of a base or a socket strip.
  • a circuit module 12 equipped with a plurality of pins (not shown), hereinafter referred to as a module, into a corresponding socket socket (not shown).
  • the module 12 has a rear edge surface 14, against which a corresponding force is exerted by the adjusting device 10 for inserting the pins.
  • the actuating device 10 contains a base plate 16 made of rigid material, such as. B. metal.
  • a base plate 16 made of rigid material, such as. B. metal.
  • On the base plate 16 a pair of rectangular contact angles 18, 20 with horizontal contact surfaces 22, 24 and vertical contact surfaces 26 and 28 are attached.
  • On the base plate 16 there are slidably mounted support plates 30, 32 - which can also be designed as a single plate - which bear against the contact angles 18, 20 in the starting position shown in FIG. 2A.
  • the support plate 32 has an inclined edge surface 34, the purpose of which will be explained later.
  • the support plates 30, 32 are provided in their upper regions with bores 36, 38 designed as a sack lock, which receive the lower ends of coil springs 40, 42.
  • the upper ends of these springs protrude into correspondingly aligned bores 44, 46, which are likewise designed as blind holes, in a pressure piece 48 which is likewise displaceably mounted on the base plate 16.
  • the pressure piece 48 has the shape of a T with a yoke part 50 with a front edge surface 52 for contacting the module 12.
  • a shaft part 54 protrudes downward from the yoke part 50 and contains parallel side surfaces 56, 58 which abut the adjacent edges of the support plates 30, 32 with only a small tolerance.
  • a transverse arm 60 is formed on the lower end of the shaft part 54, the upper surface 62 of which has a right angle to the vertical edge surface 68 of the shaft part 54.
  • the inclined edge surface 34 of the support plate 32, the side surface 58 of the shaft part 54 and the upper surface 62 of the arm 60 form a triangular chamber, within which a wedge piece 64 acting as a cam element lies movably.
  • Wedge piece 64 includes an inclined edge surface 66 to cooperate with inclined edge surface 34 of support plate 32, a vertical edge surface 68 to cooperate with side surface 58 of shaft portion 54, and a horizontal edge surface 70 which cooperates with top surface 62 of arm 60.
  • a pin 72 is fastened on the wedge piece 64, on which an actuating lever 76 is rotatably and longitudinally guided by means of an elongated hole 74.
  • a pin 78 on the contact bracket 20 or another part fixed with respect to the base plate 16 forms the fulcrum for the actuating lever 76.
  • the opposite, outer end 80 of the actuating lever 76 can be pivoted between stop pins 82 and 84, the abutment position on the stop pin 82 being the starting position of the adjusting device 10 corresponds in which the pins of the module 12 are separated from the socket, while the stop pin 84 defines the position of the actuating lever 76 when the contact pins are inserted.
  • the in Figs. 2A, 2B and 2C, stop pins 82 and 84, shown schematically, can also be designed as locking elements for the actuating lever 76.
  • the actuating lever 76 is actuated counterclockwise into its position on the stop pin 82, as a result of which the wedge piece 64 reaches the position shown in FIG. 2A.
  • the pressure piece 48 is in its lower position shown in FIG. 2A, the helical springs 40, 42 being compressed and the support plates 30, 32 on the horizontal contact surfaces 22, 24 of the contact angles 18 and 20th issue.
  • the module 12 is inserted adjacent to the edge surface 52 in such a way that its contact pins face the associated sockets (in FIG. 2A above, not shown).
  • the actuating lever 76 is pivoted away from the stop pin 82, i.e. clockwise, whereby the wedge piece 64 is moved upward and consequently the pressure piece 48 under the action of the coil springs 40, 42 for contact with the module 12 arrives so that the gap a, the size of which is not known, is now closed.
  • the module 12 is now moved further towards the socket base until the pins come into contact with the contact springs of the sockets, corresponding to the beginning of area B according to FIG. 1, as shown in FIG. 2B .
  • the coil springs 40, 42 are dimensioned with respect to their spring characteristics so that their force is sufficient, the pressure piece 48 and - after the edge surface 52 has been in contact with the edge surface 14 of the module 12 - the module 12 through the entire area A according to FIG to the beginning of area B, i.e. until it comes into contact with the contact surfaces of the bushing springs.
  • the force of the coil springs 40, 42 is not sufficient to overcome the resistance that the contact springs exert on the pins.
  • the pressure piece 48 and the module 12 stop their movement at the end of the area A after they have covered the path from the starting position (beginning of area A) to the starting position (end of area A / beginning of area B) which is not known in terms of size .
  • the support plates 30, 32 remain in contact with the contact angles 18, 20 during this adjustment process (FIG. 2B).
  • a horizontal groove 88 with a vertical stop surface 90 at one end and a flat base surface 92 is provided in a base plate 86.
  • a support block 94 arranged upright therein is cut out on one side in such a way that it forms a chamber which is delimited by an inclined edge surface 96.
  • the lower end of the support block 94 is provided with a bore 98 in the form of a blind hole for receiving one end of a helical spring 100.
  • the other end of the coil spring 100 is located in a similarly blind hole 102 in a projection 104 formed from the frame 106 downward.
  • the frame 106 frames the module 108 (shown in broken lines) on all four outer surfaces, but is a partial framing of the module 108 is also conceivable.
  • the rear edge surface 110 of the module 108 is adjacent to the rear surface 112 of the frame 106 (FIG. 4), whereby the front edge surface 114 of the module 108, from which the contact pins protrude downward into the plane of the drawing, is adjacent to the front edge surface 118 of the frame 106 is arranged.
  • An upwardly projecting stop block 120 on the frame 106 includes a stop surface 122 that defines the chamber that is formed in the support block 94 and is defined by the inclined edge surface 96.
  • a wedge piece 124 Arranged within this chamber is a wedge piece 124, to which the arm 129 of an actuating lever 130 is articulated by means of a pin 126 and an elongated hole 128, the side parts 131 of which, as shown in FIG. 4, are arranged on both sides of the frame 106.
