Abstract
Some disclosed embodiments include a retention apparatus having a unidirectional locking member, the unidirectional locking member defining a bore therethrough, a post disposed through the bore of the unidirectional locking member, wherein the post is adapted to be secured to a support base, and a spring adapted to bias the unidirectional locking member against a device to be retained, wherein the unidirectional locking member is adapted to allow movement of the device in a first direction and to inhibit movement of the device in a second direction opposite to the first direction. The retention apparatus may be used to maintain contact between a heatsink and a processor on a motherboard. Other embodiments are disclosed and claimed.
Claims22
A retention apparatus, comprising:
- a unidirectional locking member, the unidirectional locking member defining a bore therethrough;
- a post disposed through the bore of the unidirectional locking member, wherein the post is adapted to be secured to a support base;
- and
- a spring adapted to bias the unidirectional locking member against a device to be retained,
- wherein the unidirectional locking member is adapted to allow movement of the device in a first direction and to inhibit movement of the device in a second direction opposite to the first direction.
A thermal dissipation apparatus, comprising:
- a unidirectional locking member, the unidirectional locking member defining a bore therethrough;
- a post disposed through the bore of the unidirectional locking member, wherein the post is adapted to be secured to a circuit board;
- a thermal transfer device;
- and
- a spring adapted to bias the unidirectional locking member against the thermal transfer device,
- wherein the unidirectional locking member is adapted to allow movement of the thermal transfer device in a first direction and to inhibit movement of the thermal transfer device in a second direction opposite to the first direction.
An electronic system, comprising:
- a circuit board;
- an integrated circuit disposed on the circuit board;
- a heatsink positioned in thermal contact with the integrated circuit;
- and
- a retention apparatus adapted to maintain the heatsink in contact with the integrated circuit, the retention apparatus comprising:
- a unidirectional locking member, the unidirectional locking member defining a bore therethrough;
- a post disposed through the bore of the unidirectional locking member, wherein the post is secured to the circuit board;
- and
- a spring adapted to bias the unidirectional locking member against the heatsink,
- wherein the unidirectional locking member is adapted to allow movement of the heatsink in a first direction and to inhibit movement of the heatsink in a second direction opposite to the first direction.
