Patent ID: 7771219

Claim:
An IC socket comprising: an insulative stationary base defining an ellipse opening; an insulative cover mounted upon the base and defining an accommodating hole, said cover being movable relative to the base in a front-to-back direction; a metallic strengthening member sandwiched between the base and the cover and defining a driving hole; said ellipse opening, said accommodating hole and said driving hole being essentially aligned vertically; a metallic cam defining a head portion rotatively snugly received in the accommodating hole, a driving portion snugly rotatively received in the driving hole, and a positioning portion received in the ellipse opening and movable therein along a transverse direction perpendicular to said front-to-back direction; wherein said assembled base and cover defines a center line extending along said front-to-back direction, and said cam is essentially located at an end of the assembled base and cover in said front-to-back direction, while being offset from a center line of the assembled base and cover in said transverse direction so that a torque effect derived from the movement of the cover in said front-to-back direction can be eliminated by another torque effect derived from movement of the positioning portion in said transverse direction.
