Abstract

This socket permits frictionless insertion and removal of test devices. The positive contact is made between the terminals of the test device after insertion. As in drawing A, base member 20 includes terminal members 22 suitably positioned in it and a plurality of contacts 24 suitably clamped to base 20. Ring member 26 is mounted between cover 32 and base 20 and is adapted to be rotatable. Included in number 26 are four tapped holes 28 located 90 degrees apart and adapted to receive an adjusting screw. Prior to locating member 26 on member 20, cam members are positioned on member 20 and prepared to cooperate with the respective adjusting screws. Cover 32 is superimposed above the contact members and suitably secured to member 20. Openings are included in cover 32 to receive a test device 34.

Test Socket

This socket permits frictionless insertion and removal of test devices. The positive contact is made between the terminals of the test device after insertion. As in drawing A, base member 20 includes terminal members 22 suitably positioned in it and a plurality of contacts 24 suitably clamped to base 20. Ring member 26 is mounted between cover 32 and base 20 and is adapted to be rotatable. Included in number 26 are four tapped holes 28 located 90 degrees apart and adapted to receive an adjusting screw. Prior to locating member 26 on member 20, cam members are positioned on member 20 and prepared to cooperate with the respective adjusting screws. Cover 32 is superimposed above the contact members and suitably secured to member 20. Openings are included in cover 32 to receive a test device 34.

In drawing 8, an enlarged fragmentary view with cover 32 removed, when member 26 is rotated clockwise it cams member 30 into engagement with a group of contacts 24 biasing them inwardly to contact test device 34. Counterclockwise rotation of member 30 releases contacts 24, permitting frictionless entry of device 34 into the test socket.

Prior to inserting a test device, the adjusting screws are operated to permit the contact members to move away from one another.

A test device can be inserted in the openings of cover 32 without encountering any friction from the contact members. The adjusting screws are then turned to engage the contact members against the termina...
