Abstract
A heat sink fastening structure includes a push pin to fasten a heat sink to a printed circuit board (PCB) and including a head portion formed at an end thereof, a bracket mounted on the PCB and including a through hole formed at a central portion thereof to allow the head portion to penetrate, and an accommodating hole included in the PCB to accommodate the head portion therein, and the head portion is configured to penetrate the through hole and thereafter be accommodated in the accommodating hole, to thereby be fixed to the bracket.
Claims20
A heat sink fastening structure comprising:
- a push pin to fasten a heat sink to a printed circuit board (PCB), and comprising a head portion formed at an end thereof;
- a bracket mounted on the PCB and comprising a through hole formed at a central portion thereof to allow the head portion to penetrate;
- and
- an accommodating hole included in the PCB to accommodate the head portion therein,
- wherein the head portion is configured to penetrate the through hole and thereafter be accommodated in the accommodating hole, to thereby be fixed to the bracket.
A heat sink fastening structure comprising:
- a push pin to fasten a heat sink to a printed circuit board (PCB), and comprising a head portion configured to be elastically deformable, a push portion, a connection portion connecting the push portion and the head portion;
- an elastic member disposed between the head portion and the heat sink to support fastening of the heat sink to the PCB;
- a bracket mounted on the PCB and comprising a through hole formed at a central portion thereof to allow the head portion to penetrate;
- and
- an accommodating hole included in the PCB to accommodate the head portion therein,
- wherein the head portion is configured to penetrate the through hole in response to receiving an external force by the push portion, and
- the head portion is configured to penetrate the through hole by being elastically deformed to a shape passable through the through hole and thereafter the elastically deformed head portion is configured to return to an original size to be accommodated in the accommodated hole, to thereby be fixed to the bracket.
(canceled)
A heat sink fastening structure comprising:
- a push pin to fasten a heat sink to a printed circuit board (PCB), and comprising a head portion formed in a straight bar shape;
- a bracket mounted on the PCB and comprising a through hole formed at a central portion thereof and having a shape corresponding to the head portion to allow the head portion to penetrate;
- and
- an accommodating hole included in the PCB to accommodate the head portion therein and formed in a cross shape, the accommodating hole comprising a first accommodating hole formed in a shape corresponding to the head portion and having a size larger than that of the head portion, and a second accommodating hole disposed perpendicular to the first accommodating hole,
- wherein when the head portion is configured to penetrate the through hole and the first accommodating hole, and thereafter being fixed to the bracket by rotating the push pin by 90 degrees to allow the head portion to pass through the second accommodating hole but not to pass through the through hole.
