Abstract

The structure is employed as a holder or a test socket for modules provided with contact pins depending downwardly from the module about its periphery. The structure includes stationary inner ring 1 mounted on base 2. Ring 1 is surrounded by outer ring 3 which is loaded by spring 4 via bottom ring 7 which is secured to ring 3 by pin 8. Mounted on ring 1 is a second ring 5 which carries spring-loaded contactors 6 to which radial motion is imported by a series of cams 9 formed in the inner face of ring 3.

Module Holder or Socket

The structure is employed as a holder or a test socket for modules provided with contact pins depending downwardly from the module about its periphery. The structure includes stationary inner ring 1 mounted on base 2. Ring 1 is surrounded by outer ring 3 which is loaded by spring 4 via bottom ring 7 which is secured to ring 3 by pin 8. Mounted on ring 1 is a second ring 5 which carries spring-loaded contactors 6 to which radial motion is imported by a series of cams 9 formed in the inner face of ring 3.

Carried on ring 3 are clamp plates 10 having a depending cam follower 11 which coacts with cam slots 12 formed in clamp ring 13 which is loaded by a tension spring 14. In nonoperating position, the high points of cams 9 on ring 3 hold connector 6 in toward the center. Cam slots 12 concurrently hold plates 10 inwardly.

In operation, a counterclockwise rotation of ring 3 allows the low points of associated cams 9 to line up with contactors 6 and they follow a radial outward motion by the loading of spring 15. Midway in the rotation, by connection of ring 7 and clamp ring 13 by a pin 16, the accompanying rotation of clamp ring 13 causes cam slots 12 to drive cam follower 11 to open plates 10 for insertion of a pinned module 17. Releasing of spring-loaded ring 3 allows it to return thus moving plates 10 and contactors 6 inwardly. The jaws of plates 10 locate and hold module 17 while contactors 6 slide over the module pins for making an electric...
