Abstract
A heat sink with a fixture assembly has two flanges respectively formed at two opposite sides of the heat sink, a fixing unit secured on a main board at opposite sides of a CPU, a hold-down unit including two holders respectively pivoted at the opposite sides of the heat sink, and a shift unit having two shift levers respectively connected with the holders. The heat sink is easily assembled on the CPU after holding pawls of the holders are respectively caught with corresponding hooks of the fixing unit, and the shift levers are turned to a locking position in which the heat sink is securely fixed with the fixing unit and tightly abutted against an upper surface of the CPU.
Claims5
A fixture assembly for a heat sink, the fixture assembly comprising:
- a fixing unit securable on a main board and at opposite sides of a CPU, and having two pairs of hooks respectively formed at two opposite ends thereof;
- a hold-down unit having two inverted U-shaped holders respectively pivotally connected at two opposite sides of the heat sink, each holder having two lower ends formed with two holding pawls corresponding to the hooks of the fixing unit;
- a shift unit having two shift levers respectively connected with the two U-shaped holders and pivotal in a direction perpendicular to a pivotal direction of the U-shaped holder, each shift lever having a pressing end and a thumb grip end;
- whereby when the heat sink is assembled on the CPU, the holding pawls of the holders respectively catch with the corresponding hooks of the fixing unit, and the shift levers are respectively turned to a locking position, in which the pressing ends of shift levers are respectively pressed against the heat sink so as to force the heat sink to abut tightly against the CPU.
