Abstract: An IC socket (10) includes an insulative housing (12) mounted on a burn-in board, a plurality of conductive contacts (14) received in the housing. The housing defines a recessed area (120) bounded by two pairs of sidewalls (122), the recessed area defining a plurality of passageways therein. One of the sidewalls fabricates a receiving channel (1220) substantially parallel to an upper surface of the recessed area and a fastening channel (1222) substantially perpendicularly communicating with the receiving channel. A bolt (16) is screwed in the fastening channel. When the IC socket is used, a sensor (20) is received in the receiving channel and restricted in the proper position by the bolt screwed in the fastening channel.

Abstract: An electrical connector assembly (1) for electrically connecting an electronic package with a circuit substrate. The connector assembly includes a socket and a fastening device surrounding the socket. The fastening device includes a frame (2), a metal clip (3) pivotably mounted to a first end of the frame, and a cam actuator (4) pivotably mounted to a second end of the frame. The clip includes a post (3211) at a free end (32) thereof. The cam actuator includes a cam (41) defining a spiral groove (413) receiving the post and a driver (42) assembled to the cam. When the cam is driven, it drives the post downwardly, and simultaneously the clip moves slightly toward the second end of the frame. In addition, the driver at all times remains substantially within the confines of the main body of the frame.
