Patent ID: 7828575

Claim:
A test and burn-in socket for integrated circuits (ICs), comprising: a socket body, comprising: a plurality of holes through which a plurality of lower terminals of pogo contacts pass, the holes formed to prevent contact bodies from being dislodged from predetermined positions; a plurality of positioning pins to secure the socket body to a predetermined position on a printed circuit board (PCB); and a plurality of bolt insert holes used to fasten the socket body to the PCB using bolts; a contact guide having a plurality of holes through which upper terminals of the pogo contacts pass, the holes formed to prevent the contact bodies from being dislodged from predetermined positions; an IC guide provided above the contact guide to guide an IC, and comprising: a plurality of moving holes formed in a seating surface on which the IC is seated, and supporting the upper terminals ( 162 ) of the pogo contacts such that the upper terminals are vertically movable; a plurality of springs elastically supported between the IC guide and the contact guide; a cover elastically biased to the socket body via a plurality of cover springs, moving vertically from the socket body to a maximum moving distance, and including a plurality of slot plates each having a latch cam slot; a latch pressing the IC, and comprising: a fixed hole used to fasten the latch to the socket body; and a movable hole to move along an inclined surface of the latch cam slot of the cover when the latch is moved from pressing the IC to releasing the IC; and the plurality of pogo contacts each comprising: one of the contact bodies, one of the lower terminals, and one of the upper terminals that are provided in a straight-line shape; and a spring provided in the contact.
