ABSTRACT:
A retainer is disclosed for securing a heat sink having a plurality of parallel vertical fins above an electronic package which is mounted on a socket. The retainer comprises a clip assembly including a clip having a pair of spaced apart beams dimensioned to span the heat sink and to reside in respective grooves between respective pairs of adjacent ones of the fins. The beams are resiliently deflectable in respective planes extending parallel to the fins. One end of the clip is engageable beneath a ledge on one side of the socket. An opposite end of the clip is pivotally coupled to a latch. The latch is engageable beneath a second ledge on an opposite side of the socket upon deflection of the beams in their respective planes. The clip assembly biases the heat sink toward the socket when the one end of the clip and the latch are engaged beneath the first and second ledges. A toggle coupled between the clip and the latch is movable between open and closed positions to engage and disengage the latch with the second ledge. The toggle has an overcenter position corresponding to the closed position such that a force must be applied to the toggle to move the toggle from the closed to the open position.
