Device for the production of electrical contact connections with the contacts of a plug device, in particular test fixtures for the connection of electrical components, which is provided with a plug-in device to a test equipment

摘要

A pneumatically controlled electrical test connector 10 contains spring-loaded pins 34 whose ends are brought into electrical contact with the opposing ends of corresponding connector pins 4 of an electronic module 1 secured and orientated in a support frame 11 of the connector 10. The pins 34 of the pneumatically controlled connector 10 are recessed to centre the ends of the module connector pins 4. Pneumatic cylinders 25 secured to the support frame have piston rods 26 engaged with a slide 20 in which the spring-loaded pins 34 are longitudinally movably mounted, each pin 34 having a collar 36 and a spring 37 trapped between headers 31' and 31'' secured to opposite sides of the slide 20. When actuated, the cylinders 25 draw in the rods 26 and thus produce sufficient force between the opposing pins of the test and module connectors to thereby establish good electrical contact at the contacting pin ends. The spring 37 on each pin 34 accommodates the mechanical tolerances of the pin lengths and causes the force on each pin to be substantially equal. Commercially available connectors 39 are slipped onto the other ends 35' of the test connector pins 34 for wiring of the test connector 10 to a test set. IMAGE
