ABSTRACT:
A contact shutter mechanism in an IC socket has a socket body which has a plurality of contacts arranged in such a manner as to be able to contact with terminals of an IC package. A contact shutter member vertically movably disposed on the socket body is adapted to displace, when pushed down, the contacts backward against the resiliency thereof to remove contact between the terminals of the IC package and the contacts and to bring an IC loading portion into a released state. The shutter member has a contact pushing portion adapted to rendering a backward displacement force to the contacts. The contact pushing portion is formed with an inclined surface. The inclined surface is formed at a front-stage pushing portion with a gently inclined surface and at a rear-stage pushing portion with a steeply inclined surface.
