Abstract
Abstract A socket for securing an integrated circuit (IC) during burn-in or test procedures. The socket includes a base which carries a plurality of electrically conductive contacts. Opposed hold down latches are shiftably connected to the base and include outer cams. The socket also includes a movable top which has an integral nib for contacting the latch cams to effect shifting of the latches. A rotatable lever housed in the base is connected to an actuating arm which is shiftable by movement of the top. The lever is operably associated with the contacts and shifts the contacts between an operative position in contact with the IC leads and a standby position spaced from the leads.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
A socket for housing an integrated circuit, said integrated circuit including a body and a plurality of leads extending outwardly of said body, said socket comprising a base, a plurality of electrically conductive contacts housed in said base, latch means shiftably connected to said base for securing said integrated circuit to said socket, actuator means movably connected to said base for shifting said latch means between a normally latched position overlying said circuit body wherein the integrated circuit may be removed, said actuator means further including means for shifting said contacts between a first position contacting said circuit leads with the latch means in said latched position and a second position spaced from the leads with the latch means in the unlatched position, said latch means including an integral outwardly projecting terminal cam part, said actuator means including an integral inner projection contacting said cam part to shift said latch means as said actuator means is moved relative to the base.
Claim 2
Dependent Claim
161 words
A socket for housing an integrated circuit, said integrated circuit including a body and a plurality of leads extending outwardly of said body, said socket comprising a base, a plurality of electrically conductive contacts housed in said base, latch means shiftably connected to said base for securing said integrated circuit to said socket, actuator means movably connected to said base for shifting said latch means between a normally latched position overlying said circuit body wherein the integrated circuit may be removed, said actuator means further including means for shifting said contacts between a first position contacting said circuit leads with the latch means in said latched position and a second position spaced from the leads with the latch means in the unlatched position, said latch means including an integral outwardly projecting terminal cam part, said actuator means including an integral inner projection contacting said cam part to shift said latch means as said actuator means is moved relative to the base.
Claim 3
Dependent Claim
61 words
