Abstract:
1. A socket for an electrical part comprising a module accommodating a contact pin, in which one terminal of the contact pin is connected to a terminal of an IC package and the other terminal of the contact pin is connected to a circuit formed on a substrate; wherein the module comprises, a first holding plate which has a first hole to accommodate a held portion of the other terminal side of the contact pin so as to be vertically movable, a second holding plate which is disposed on the first holding plate so as to be vertically separative from the first holding plate and horizontally slidable from the first holding plate, and has a second hole to make the contact pin to be passed through, a urging member which urges the second holding plate toward the first holding plate, and a pushing-up portion which is formed at the held portion of the other terminal side so as to contact to the lower side of the second holding plate and to separate the second holding plate from the first holding plate against a urging force of the urging member when a tip of the other side of the contact pin is pressed onto the substrate and the held portion of the other terminal side of the contact pin moves toward a direction in which the held portion buries in the first hole under a state the second hole of the second holding plate is shifted against the first hole of the first holding plate.
