Abstract:
A socket for an electric part, comprising a plurality of contact pins disposed on a socket body extending in a vertical direction and capable of being brought into and out of contact with terminals of the electric part and a slide plate disposed on the socket body and movable in a lateral direction so that tip ends of said contact pins are opened and closed to come into and out of contact with the terminals of the electric part by moving said slide plate in said lateral direction by an operating member, wherein said slide plate includes contact pin-operating portions provided thereon for opening said contact pins, and operating grooves defined therein and each having a tapered face, and said operating member includes operating arms disposed thereon and engaging into said operating groves in said slide plate, so that said operating arms urge the tapered faces of said operating grooves by urging said operating member downwards, thereby directly moving said slide plate, each of said contact pins is comprised of three resilient pieces: two movable resilient pieces and a single stationary resilient piece, said movable resilient pieces being capable of being opened in such directions that they are spaced apart from each other, each of said movable resilient pieces has an inclined guide face formed thereon, and each of said contact pin-operating portions is a contact pin-operating bore having an inclined face forced therein and abutting against said inclined guide face, so that said movable resilient pieces are opened in a direction perpendicular to a direction of movement of the slide plate by urging said inclined guide face by said contact pin-operating bore by the movement of said slide plate.
