Abstract
A fastener for a heat-dissipating device is adapted to secure a heat sink on a securing seat. The fastener includes a fastening arm having a plate body and a coupling member adapted to couple with one positioning member of the securing seat, a fastening member disposed spacedly below the plate body opposite to the coupling member and adapted to couple with another positioning member, and two linkage sets. Each linkage set is disposed between the plate body and the fastening member, and includes first and second resilient connecting elements connected respectively to the plate body and the fastening member. The linkage sets are pivotable toward each other to cause the plate body to displace toward the fastening member such that the linkage sets engage two openings in the securing seat.
Claims20
A fastener for a heat-dissipating device, said fastener being adapted to secure a heat sink on a securing seat, the securing seat including two positioning members disposed respectively on two opposite sides of the securing seat, and two openings disposed respectively in two opposite sides of one of the two positioning members, said fastener comprising:
- a fastening arm having a coupling member and a plate body disposed respectively at two opposite ends thereof, said coupling member being adapted to couple with one of the positioning members;
- a fastening member disposed spacedly below said plate body of said fastening arm and opposite to said coupling member, said fastening member being adapted to couple with the other of the positioning members;
- and
- two linkage sets, each of which is connected to and is disposed between said plate body and said fastening member, said two linkage sets being disposed respectively on two opposite sides of said plate body and of said fastening member, each of said linkage sets including a first resilient connecting element connected to said plate body, and a second resilient connecting element connected to said fastening member, said two linkage sets being pivotable toward each other in a direction of said fastening member within a determined angle, with said first and second resilient connecting elements serving as axes, and being capable of bringing said plate body to displace downward toward said fastening member such that said two linkage sets are adapted to engage the two openings, respectively.
A heat-dissipating device adapted to dissipate heat from an electronic component on a circuit board, said heat-dissipating device comprising:
- a heat sink;
- a securing seat adapted to be mounted on the circuit board and for mounting of said heat sink, said securing seat including two positioning members disposed respectively on two opposite sides of said securing seat, and two openings, said openings being respectively formed in two opposite sides of one of said positioning members;
- and
- a fastener including
- a fastening arm for abutting against said heat sink and having a coupling member and a plate body disposed respectively at two opposite ends of said fastening arm, said coupling member being disposed to engage one of said positioning members of said securing seat,
- a fastening member disposed spacedly below said plate body of said fastening arm and disposed to engage the other of said positioning members of said securing seat, and
- two linkage sets, each of which is connected to and is disposed between said plate body and said fastening member, said two linkage sets being disposed respectively on two opposite sides of said plate body and of said fastening member, each of said linkage sets including a first resilient connecting element connected to said plate body, and a second resilient connecting element connected to said fastening member, said two linkage sets being pivotable toward each other in a direction of said fastening member within a determined angle, with said first and second resilient connecting elements serving as axes, and being capable of bringing said plate body to displace downward toward said fastening member such that said two linkage sets respectively engage said two openings in said securing seat.
