Socket for electrical parts

Abstract

A socket for an electrical part includes a socket body provided with a mount surface portion on which an electrical part having terminals are mounted, number of contact pins disposed to the socket body and having contact portions so as to be contacted to or separated from the terminals of the electrical part, respectively, a movable plate disposed to the socket body to be movable, the contact portions of the contact pins being contacted or separated from the terminals of the electrical part through movement of the movable plate, and an operation member disposed to the socket body and adapted to move the movable plate. Each of the contact pins is provided with a pair of fulcrum portions, a pair of clamping pieces which perform pivotal motion about the fulcrum portions, a pair of contact portions formed, at front end portions thereof, to the clamping pieces so as to establish electrical connection between the contact pin and the terminal when the terminal is clamped between the contact portions, and a pair of press portions to be pressed by the movable plate including force acting portions on which pressing force of the movable plate is applied. The contact portions and the force acting portions of the contact pin are formed to positions opposite to each other with respect to the fulcrum portions.
