Integrated circuit (IC) socket with contoured capture groove

摘要

An improved test socket for testing or connecting an integrated circuit is disclosed having a platform for receiving the integrated circuit and adapted to overlay a piece of test equipment or other board, the platform formed with an array of slots each locating a portion of a two-piece connector assembly. The socket includes a conforming groove that captures an elastomer member therein while providing exposure of the elastomer member to a link assembly. The socket, with the capture groove, provides improved contact of the link assembly and reliability in locating and maintaining positioning of the elastomer member.

1. An improved socket for electrically coupling an integrated circuit (IC) to a board so that a signal may be transmitted thereto, comprising:
a platform for receiving the integrated circuit thereon; an elongate resilient tubular member housed in the platform; and a plurality of two-piece connector assemblies, each connector assembly comprising a mount and an associated link pivotable about the mount, each connector assembly having first and second positions, the first position comprising an engaged position wherein an electrical contact is established between the integrated circuit and the board, and a standby position where the link does not establish an electrical contact between the integrated circuit and the board; wherein the mounts are retained in the platform and comprise a curved cavity on a lateral side opposite an associated link member; and wherein the associated link member has an arcuate contact surface on an upper side adapted for rolling contact with the integrated circuit, a rocker arm laterally displaced with a bulb-shaped tip seated in the curved cavity of the mount, the link vertically pivotable about bulb tip, and a downwardly sloping leg member wherein the elongate resilient tubular member biases the connector assemblies in the standby position; and wherein the socket includes a groove for receiving the elongate resilient member, the groove having a profile that substantially coincides with a profile of the elongate resilient member.
