Patent ID: 7661962

Claim:
A socket for an electric component comprising: a socket main body having an accommodating portion therein for accommodating an electric component; a plurality of contact pins disposed in the socket main body and capable of coming in contact with or separating from each of connection terminals of the electric component; a socket cover mounted on a top of the socket main body to be capable of performing an up and a down movement; a slide plate vertically movably disposed in the socket main body to cause a displacement of the contact pins thereby permitting the contact pins to come into contact with or separate apart from each of the contact terminals of the electric component; and drive levers which are provided between the socket main body and a bottom face of the socket cover and configured to press both end portions on two opposing sides of the side plate, which oppose to each other, in response to the down movement of the socket cover to lower the side plate, wherein: sub-levers are provided between the socket main body and the bottom face of the socket cover to press one or plural positions of other opposing two sides of the slide plate, which oppose to each other in a direction perpendicular to the two opposing sides pressed by the drive levers, to thereby lower the slide plate; the sub-levers are disposed to press a central portion of the other opposing two sides of the side plate, which oppose to each other in the direction perpendicular to the two opposing sides pressed by the drive levers; after the drive levers press both end portions on the opposing two sides of the side plate, which oppose to each other, and a deformation of the side plate becomes larger than a predetermined amount, the sub-levers are configured to apply a press to the other opposing two sides of the slide plate, which oppose to each other in the direction perpendicular to the two opposing sides pressed by the drive levers; and a lever motion ratio exhibited by the drive lever to lower the slide plate in response to the down movement of the socket cover is set larger than a lever motion ratio exhibited by the sub-lever to lower the slide plate in response to the down movement of the socket cover.
