Abstract:
A socket for an electrical part comprising:a socket body having a mount portion on which an electrical part having a plurality of terminals is mounted; a plurality of contact pins arranged on the socket body and each having an elastic property, said contact pins being adapted to contact the terminals and separate therefrom, respectively, an operation member arranged for the socket body to be vertically movable in a mounted state, said operation member having four side portions providing a substantially rectangular frame shape, at least one of said four side portions being provided at an outer surface of said at least one of the side portions with a cam portion, each of said contact pins being formed with a movable contact piece, each of said movable contact pins configured for contacting each of the terminal of the electrical part, when the operation member is moved downwardly along a vertical direction, each of said movable contact pins being pressed by the cam portion of the operation member to be deformed so as to contact and separate from each of the terminals such that a repulsive force generated from the contact pin, which is pressed by the cam portion of the operation member, is applied on the cam portion; and deformation restriction means mounted to an intermediate portion on an inner surface of said at least one of the side portions such that at least one of said plurality of contact pins lies opposite to or outside of said deformation restriction means, a mount portion of said deformation restriction means on the inner surface being opposite to the cam portion on the outer surface, said deformation restriction means being adapted to abut against a portion of the socket body in the vicinity of the contact pin at a time when the operation member moves towards the most lowered position so as to restrict inward deformation of the operation member due to the repulsive force from the contact pin, wherein said deformation restriction means comprises a rib member formed on the inner surface of the at least one side portion of the operation member and adapted to abut against the socket body at a time of lowering the operation member and to restrict the inward deformation fo the operation member from occurring.
