Abstract
A socket has a base (10) that is to be fixed on a printed wiring substrate (not shown in the drawings) and a cover (12), in the shape of a square frame, that is reciprocably movable in the vertical direction relative to base (10). An adaptor (20) is fixed to the center of base (10) by means of bolts (22) and an elevator carrier (24) is mounted on adaptor (20) in such a manner as to move among first, second and third vertically disposed positions in dependence upon movement of the cover (12). A large number of contact elements (26) are arranged in a pattern corresponding to the lead terminal pattern of an IC package for loading in the socket. Above each contact row, there is provided a linkage mechanism (32, 36) including a laterally extending bar (36a) movable toward and away from contact elements (26) in dependence upon the vertical movement of the cover (12).
