Socket for electrical parts

Abstract

A socket for an electrical part comprises a socket body provided with a mount portion on which an electrical part such as IC package is mounted, a plurality of contact pins mounted to the socket body to be separated from and contacted to terminals such as IC leads of the electrical part and an upper operation member disposed to the socket body to be vertically movable. The contact pins each comprises a stationary contact piece to be contacted to a lower surface of the terminal and a movable contact piece to be contacted to an upper surface of the terminal so as to clamp the terminal therebetween in a manner that when the upper operation member is moved vertically, the movable contact piece is deformed to be separated from and contacted to the terminal. The stationary contact piece has an upper surface higher, in a level in a mounted state, than an upper surface of the mount portion of the socket body and the socket body is formed with a plurality of projections at portions near the stationary contact pieces so that a gap is formed between each of the projections and each of the stationary contact pieces so as to have a width smaller than a width of the terminal to prevent the terminal from falling out therethrough.
