Patent ID: 8272609

Claim:
A bracket for mounting a heat sink on a printed circuit board, the bracket comprising: two supports; two rails mounted between the supports, opposite ends of each of the rails received in the corresponding supports and slidable along a first direction in which each of the supports extends, each of the rails defining two slide slots each extending through one of the opposite ends of the rail and extending along the rail, wherein the supports and the rails are attached to a first side of the printed circuit board; four positioning members extending through the supports to engage with the rails to position the rails on the supports; and four adjusting assemblies respectively attached to the slide slots of the rails, the adjusting assemblies are adjustably received in the corresponding slide slots along a second direction substantially perpendicular to the first direction, wherein the adjusting assemblies are to extend through the circuit board to engage with the heat sink at a second side of the printed circuit board opposite the first side; wherein each of the supports comprises a rectangular bottom wall, a top wall opposite and parallel to the bottom wall, a sidewall substantially perpendicularly connected between corresponding sides of the top and bottom walls, and an end wall substantially perpendicularly connected between corresponding ends of the top and bottom walls, a receiving space is bounded by the top wall, bottom wall, sidewall, and end wall, the corresponding ends of the rails are received in the receiving spaces of the supports; wherein the opposite ends of each of the rails comprise two recessed engaging portions to be received in the supports.
