ABSTRACT:
A socket for receiving an IC chip having ball-shaped pins is disclosed. The socket includes a base having a plurality of through holes defined therein, a sliding cover housing the base and having a central opening for permitting the IC chip to be inserted therethrough, and an actuating rod located between the base and the cover for causing a sliding movement of the cover relative to the base. Each of said through holes has a contacting leg disposed therein and said leg has a first end extending beyond an upper face of the base and a second end extending through a bottom of the base. Said first end has an arcuate surface which is perpendicular to the sliding movement of the IC chip and has a curvature equal to that of the ball-shaped pin of the IC chip so as to make an electrical surface contact with the ball-shaped pin when the IC chip is moved to be fastened on the base.
