Abstract: A ZIF socket (1) includes a base (2), a cover (3) movably mounted on the base, a plurality of contacts received in the base, and a cam mechanism (4) engaged with the cover and the base. The cam mechanism comprises a cam device (41) and a base ring (42) assembled on the cam device. The cam device is composed of five column-shaped portions, the diameters of which are successively decreasing from the uppermost one to the lowermost one. A topside of the base ring abuts directly against a supporting surface (417) formed on the cam device to reduce the frictional force required to overcome during rotating the cam mechanism.

Abstract: A ZIF socket connector (20) includes a base (22), a cover (24), an actuator (26) and a number of electrical contacts (30). The cover is movably assembled to the base and the base defines a plurality of openings (221) extending therethrough to receive the electrical contacts. Each electrical contact has a base portion (31), a solder portion (32) extending from the base portion, and a contacting portion (34) having a pair of arms (35). Each arm has a descending section (350), a horizontal section (351) extending from the descending section and a resilient section (352) extending from the horizontal section. The resilient sections of each electrical contact have free ends so twisted as to press therebetween and electrically contact a corresponding pin (42) of an electronic package (40).
