Patent ID: 7568918

Claim:
A socket for a semiconductor device comprising: a socket body having a semiconductor device mounting portion for detachably mounting a semiconductor device and a group of contact terminals electrically connected to terminals of said semiconductor device; a presser member having a pressing surface portion formed generally parallel to a contour surface of said semiconductor device and said presser member being supported in said socket body so that said pressing surface portion is moved in the direction vertical to said contour surface and brought into contact with said contour surface when moving closer to the contour surface of said semiconductor device mounted to said semiconductor device mounting portion or rotated after said pressing surface portion is away from the contour surface; a cover member supported by said socket body to be movable upward and downward and having an opening for allowing said semiconductor device to pass therethrough when said semiconductor device is mounted or demounted; means for biasing said cover member in the direction away from said socket body; and a link mechanism coupled to said cover member and said presser member, for holding said pressing surface of said presser member on the contour surface of said semiconductor device or releasing the same therefrom in synchronization with moving up and down of said cover member.
