Claim:
A pin grid array package socket for receiving a pin grid array package having a plurality of lead pins, the pin grid array package socket comprising: a base housing having a positioning hole and a plurality of terminals arranged in the form of a grid; and a slide plate having a plurality of through holes made in the form of a grid corresponding to the plurality of terminals, the slide plate being laid on the base housing, and being movable between a first position in which the lead pins are permitted to be inserted in the base housing and a second position in which the lead pins are put in contact with the terminals mounted in the base housing, characterized in that the base housing has a cam member rotatably fitted in the positioning hole such that rotation of the cam member allows an outer periphery of the cam member to engage a counter surface of the positioning hole, and wherein a pushing force directed to the counter surface is directed at a position offset from the counter surface such that a kickback force will not move the slide plate from the second position to the first position.
