Patent ID: 7819686

Claim:
A burn-in socket, for electrically connecting an IC package to a printed circuit board, comprising: base for receiving the IC package; a lid assembled upon the base and being movable relative to the base; and a plurality of latches, each latch having a first shaft pivotally linking to the base and a second shaft pivotally linking to the lid, the latch defining a through hole extending aslant and receiving the second shaft, the second shaft being caused, in response to the lid moving up and down relative to the base, to move up and down in the through hole and forcing the latch to rotate; the latch formed with a retaining portion and a latching portion extending from the retaining portion, and the through hole defined on a top end of the retaining portion and near an out side and extends upwardly and outwardly; the base comprising four guiding slots with two sidewalls; four guiding pins each defining a pivoting hole receiving the corresponding first shaft of the latch; the sidewall of the base provided with a plurality of leading slots and locking clumps located in the leading slots, the lid having a plurality of guiding legs inserted into the corresponding leading slots, and each guiding leg having a claw engaging with the corresponding locking clump; the lid having two pivoting portions, each pivoting portion defining a position hole receiving and retaining the corresponding second shaft of the latch; wherein when the second shaft is moved to one end of the through hole, the lid is rotated to a locking position for locking said electronic package in a receiving cavity; when the second shaft is moved to the other end of the through hole, the lid is rotated to an open position for unlocking the electronic package and allowing said electronic package to move upward from the receiving cavity.
