Description
- 1. Technical Field
- The invention relates to heat sinks, particularly to fasteners for fixing a heat sink on an electronic device.
- 2. Related Art
- With the advancement of semiconductor technology, electronic components such as the CPUs run with higher and higher frequency. Thus heat sinks for electronic components have become indispensible. A heat sink must be firmly mounted on an electronic component by a fastener. Such a fastener must be easy to be installed and detached.
- Taiwan patent No. 505267 discloses a typical heat sink fastener. TW '267 employs a lever to install or detach the heat sink, but the lever is in direct contact with the heat sink. However, some heat sinks may be improper for being directly depressed because direct depression may cause damage, deformation or instability.
- An object of the invention is to provide a heat sink fastener which may prevent the heat sink from being damaged by means of indirect depression.
- To accomplish the above object, the fastener of the invention includes a frame seat, a latch and two depressors. The frame seat is formed with a hollow for accommodating the heat sink and the latch is moveably mounted on the frame seat. The depressors may be selectively pressed or released by the latch against the frame seat. The heat sink can be fastened by the depressors when the depressors are pressed by the latch.

FIGS. 1 and 2 . The invention provides a fastener for fixing aheat sink 2 onto anelectronic component 30 on acircuit board 3. Thefastener 1 includes aframe seat 10, alatch 11 and twodepressors 12. - The
frame seat 10 is formed with a hollow 100 for accommodating theheat sink 2. Theheat sink 2 includes abase 20 and a fin set 21 thereon. When theheat sink 2 is placed in the hollow 100 of theframe seat 10, thebase 20 of theheat sink 2 may be in contact with theelectronic component 30. Theframe seat 10 is provided with a plurality offixing holes 101 for being fixed on thecircuit board 3 by aflexible fixer 31 as shown inFIG. 6 . - The
latch 11 is moveably mounted on theframe seat 10 to depress or release thedepressors 12. Please refer toFIGS. 3-5 . Thelatch 11 may be rotated to press thedepressors 12 when theheat sink 2 has not been fixed on theelectronic component 30 yet. Then theheat sink 2 can be fastened on theelectronic component 30 by thedepressors 12 because thedepressors 12 are pressed by thelatch 11. - Please refer back to
FIGS. 1 and 2 . In the shown embodiment, thelatch 11 is formed into a U shape. Two ends of theU-shaped latch 11 are separately formed with twoprotrusions 110 corresponding to twoopposite side walls 102 of theframe seat 10. Each of theside walls 102 is provided with areceiving hole 103 for receiving theprotrusions 110. Theprotrusions 110 are unfixedly inserted into thereceiving holes 103 when thelatch 11 is perpendicular to theframe seat 10 as shown inFIG. 3 . Theprotrusion 110 is further extended with ahook 111 which can prevent theprotrusion 110 from escaping thereceiving hole 103 when thelatch 11 exerts pressure between theframe seat 10 anddepressors 12 as shown inFIG. 5 . Furthermore, an upper edge of thereceiving hole 103 is formed with aslant 104 for guiding theprotrusion 110 to lean against one side of thereceiving hole 103. Besides, two ends of thelatch 11 are further separately formed with twopressing portions 112. - The
depressors 12 are pressed by thelatch 11 to exert pressure onto theheat sink 2. In other words, theheat sink 2 is not directly pressed by thelatch 11 to avoid damage. In the shown embodiment, each of thedepressors 12 is formed into a zigzag plate including an upper pressedsection 120 and a lowerpressing section 121. The pressedsection 120 is pressed by thepressing portion 112 of thelatch 11 and thepressing section 121 overlaps thebase 20 of theheat sink 2 as shown inFIG. 6 . The zigzag shape of thedepressor 12 may provide an effect of buffer to reduce damage to theheat sink 2. The pressedsection 120 may be further extended with a connectingsection 122 having a connectinghole 123. Theframe seat 10 is provided with a connectingsheet 105 inserted into the connectinghole 123. The connectinghole 123 is larger than the connectingsheet 105 in size, so the connectinghole 123 may be movably inserted by the connectingsheet 105. This can provide a positioning effect between thedepressor 12 and theframe seat 10. - The
pressing section 121 of thedepressor 12 is provided with at least one threadedhole 124 and thebase 20 is provided with at least one throughhole 200 corresponding to the threadedhole 124. Abolt 201 may pass through the throughhole 200 to screw into the threadedhole 124 for fastening thedepressor 12 on theheat sink 2. As shown inFIG. 5 , theframe seat 10 is provided with anut post 106 and thelatch 11 is provided with afixing hole 113 corresponding to thenut post 106. Anotherbolt 114 may pass through thefixing hole 113 to screw into thenut post 106 for fastening thelatch 11 on theframe seat 10. - While the forgoing is directed to a preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. As such, the appropriate scope of the invention is to be determined according to the claims.
