Abstract:
An IC socket comprising:a socket body elastically supporting a cover having an IC loading window, said cover being vertically movable toward and away from said socket body; and a plurality of contact pins attached to said socket body for connecting IC terminals and an external electric testing circuit, each of said contact pins comprising: a base portion fixed to said socket body; a first contact portion connected to said base portion via a first spring portion for supporting corresponding one of said IC terminals, said first spring portion having a curved shape for generating a tensile or compressive stress in said first spring portion when it is elastically deformed; and a second contact portion connected to said base portion via a second spring portion, said second contact portion forced by said cover, when said cover is moved toward said socket body, so as to elastically deform said second spring portion so that said second contact portion retreats from said first contact portion to allow said one of said IC terminals to be received on said first contact portion, and said second contact portion pressing said one of said IC terminals against said first contact portion by means of an elastic force of said second spring portion when said cover returns to an initial position, wherein each of said first contact portions is formed with a stepped portion, and said socket body is formed with an engaging portion which engages with said stepped portion in a state where said first spring portion is elastically deformed, so that said stepped portion is vertically pressed against said engaging portion by an elastic force of said first spring portion caused by said tensile or compressive stress generated in said first spring portion, thereby to carry out vertical positioning of said first contact portion.
