Abstract
A heat sink assembly (10) compatible with an ATX motherboard (20) and a BTX motherboard (30), includes a heat sink and a plurality of fasteners (15) extending through the heat sink. The heat sink includes a base (12) defining a slot (1220) therein. The fastener is capable of sliding along the slot between a first position to a second position to make the heat sink assembly in accordance with the preferred embodiment of the present invention to be adapted for use with the ATX motherboard or the BTX motherboard.
Claims7
A heat sink assembly compatible with an advanced technology extended (ATX) motherboard and a balanced technology extended (BTX) motherboard, the heat sink assembly comprising:
- a base adapted for contacting with a heat generating device on one of the ATX and BTX motherboards, a slot defined in the base;
- a plurality of fins mounted on the base;
- and
- a fastener for fixing the base to the heat generating device, the fastener extending through the base and being slidable horizontally along the slot from a first position to a second position;
- wherein the fastener comprises a screw having a head and a shaft extending downwardly from the head, and a spring mounted around the shaft and located between the head of the screw and the base;
- wherein the slot has two ends, and each of the ends terminates with an aperture communicating with the slot, the aperture is used for providing passage of the fastener;
- wherein a step portion is formed in the aperture for supporting the spring thereon;
- wherein a recess is defined in the shaft of the screw thereby forming an engaging portion at the recess, and the engaging portion is slidable along the slot in the base;
- wherein the engaging portion has an outer diameter smaller than a width of the slot and a height larger than that of the base;
- and
- wherein an annular pad engages with the engaging portion and abuts against a joint of the engaging portion and the shaft at a bottom of the engaging portion.
A heat sink assembly comprising:
- a heat sink defining a slot, the heat sink comprising a base and a plurality of fins extending upwardly from the base;
- a plurality of ears formed at corners of the base, the slot being defined in one of the ears;
- and
- a fastener comprising a head and a shaft extending from the head, the shaft having a threaded bottom end;
- wherein the shaft extends through the slot and is horizontally slidable along the slot between first and second positions for different motherboards having different specifications, respectively;
- and
- wherein the base defines two holes at the first and second positions, respectively, each of the holes having a diameter larger than a width of the slot, the shaft having a middle engaging portion with a diameter smaller than upper and lower end portions of the shaft, the engaging portion being received in the slot during a horizontally sliding movement of the shaft along the slot, the upper and lower end portions of the shaft each having a diameter larger than the width of the slot and smaller than that of each of the holes.
