ABSTRACT:
A burn-in socket is shown including a latch member (60) capable of moving leads (101) of an IC package (100) received on a seat (200) on a base member (20), biasing the leads into engagement with movable contact arms (212) of contacts (21) mounted in the base member. A linking mechanism (50), movable in dependence upon the vertical movement of a cover member (30), transmits the cover member movement to latch member (60). Linking mechanism (50) has an arm (52) pivotably connected at one end to the cover member (30) and at an opposite end to a lever body (54) intermediate opposite ends thereof. The lever body has one end pivotably connected to base member (20) and its opposite end connected to latch member (60). A return spring (40) places a bias on the cover to maintain it normally separated from the base member and provides a selected contact force. The socket can be used with a wide variety of IC package types either before or after leads extending from the IC package have been formed.
