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.
Claims20
A fixture assembly comprising:
- a heat sink;
- at least a first fixing unit securable on a main board, with the at least first fixing unit having at least a first pair of hooks formed at two opposite ends thereof;
- and
- a hold-down unit for each pair of hooks, with each hold-down unit having a U-shaped holder pivotally connected at two opposite sides of the heat sink in a pivot direction, with the U-shaped holder having two lower ends formed with two holding pawls corresponding to the pair of hooks of the fixing unit;
- with the hold-down unit having a shift lever connected with the U-shaped holder and pivotal in a direction perpendicular to the pivotal direction of the U-shaped holder, with the shift lever having a pressing end and a thumb grip end;
- whereby when the heat sink is assembled on the main board, the holding pawls of the U-shaped holder catch with the pair of hooks of the fixing unit, and the shift lever is turned to a locking position, in which the pressing end of the shift lever is pressed against the heat sink so as to force the heat sink to abut tightly against a CPU mounted on the main board.
A fixture assembly comprising:
- at least a first fixing unit adapted to be mounted on a main board and having at least a first pair of hooks formed at two opposite ends thereof;
- and
- a hold-down unit for each pair of hooks, with each hold-down unit having a U-shaped holder adapted to be pivotally connected at two opposite sides of a heat sink, with the U-shaped holder having two lower ends formed with two holding pawls corresponding to the pair of hooks of the at least first fixing unit;
- and
- with each hold-down unit having a shift lever connected with the U-shaped holder and pivotal in a direction perpendicular to a pivotal direction of the U-shaped holder, with the shift lever having a pressing end and a thumb grip end;
- whereby when the holding pawls of the U-shaped holder catch with the pair of hooks of the at least first fixing unit, and the shift lever is turned to a locking position where the pressing end of the shift lever is pressed against the heat sink so as to force the heat sink to abut tightly against a CPU mounted on the main board.
