Patent ID: 6848928

Claim:
A socket for use with a semiconductor device having a top surface and a bottom surface with a plurality of terminals on a bottom surface comprising a base, an adaptor member received on the base having a seating surface for said semiconductor device, the adaptor member having a plurality of contact member receiving holes extending through the seating surface, a cover which is arranged on the base and supported for straight line movement between a first position in which the cover is apart from the base and a second position in which the cover is adjacent to the base, a plurality of contact members having tips received in each of the contact member receiving holes to be placed in contact with each terminal of the semiconductor device placed on the seating surface, and a rotary latch member having a rotational axis fixed to the base being movable in conjunction with the movement of said cover member, said latch member having a tip portion onto which a compressive part member is mounted so as to be able to pivot with regard to said tip portion, said compressive part member being positions to be capable of pressing said semiconductor device against said seating surface when said semiconductor device is on said seating surface and said cover member is in said first position for providing reliable electric contact between said plurality of terminals and said plurality of contact members while not damaging said semiconductor device due to said compressive part member marking wide area contact with said top surface of said semiconductor device.
