Description
- 1. Field of the Invention
- The present invention relates to securing of heat sinks to electronic devices, and particularly to heat sink clip assemblies having handles for facilitating operation.
- 2. Related Art
- Advances in microelectronics technology have resulted in electronic devices which process signals and data at unprecedented high speeds. During operation of many contemporary electronic devices such as central processing units (CPUs), large amounts of heat are produced. The heat must be efficiently removed, to prevent the system from becoming unstable or being damaged.
- Typically, a heat sink assembly comprises a heat sink, a fan and a clip attached at a periphery of the electronic device. The clip is often integrally made of spring steel wire. An example of such heat sink assembly is disclosed in Taiwan Patent No. 332721. A wire clip comprises a horizontal pressing section and two spring arms extending from two opposite ends of the pressing section. A hook is formed at a distal end of each spring arm, to resiliently engage with a part at a periphery of the electronic device. The clip thereby presses the heat sink onto a top surface of the electronic device. Unfortunately, the wire is typically small and slippery. In assembly, an operator's finger is prone to slip off the surface of the clip. The resultant inconvenience and inefficiency is particularly costly in mass production assembly lines.
- Thus, an improved heat sink clip assembly which overcomes the above problem is desired.
- Accordingly, an object of the present invention is to provide a clip assembly which readily and securely attaches a heat sink to an electronic device.
- Another object of the present invention is to provide a clip assembly with handles for facilitating operation.
- A further object of the present invention is to provide a clip assembly which is simple and cost-efficient.
- To achieve the above-mentioned objects, a heat sink clip assembly comprises a clip and a pair of handles attached to the clip for facilitating operation. The clip is integrally made of spring steel wire. The clip has a horizontal pressing section and two spring arms extending perpendicularly from opposite ends of the pressing section. The spring arms extend generally upwardly in different directions from the pressing section. A hook is formed at a free end of each spring arm. Each handle has a rectangular base plate and two fixing blocks formed at diagonally opposite comers of the base plate. The fixing blocks extend toward each other along a pair of orthogonal edges of the base plate. A groove is defined in an inner side surface of each fixing block. The grooves are parallel to the base plate and respectively accommodate part of the pressing section and part of one of the spring arms.
- Other objects, advantages and novel features of the present invention will be drawn from the following detailed description of a preferred embodiment of the present invention together with the attached drawings, in which:
- FIG. 1 is an exploded view of a heat sink clip assembly in accordance with the present invention, used in conjunction with a fastener to press a heat sink onto a chipset mounted on a motherboard;
- FIG. 2 is a perspective view of a handle of the heat sink clip assembly of FIG. 1; and
- FIG. 3 is an assembled view of FIG. 1.
- Referring to FIG. 1, a heat sink clip assembly in accordance with the present invention comprises a
clip 20 and a pair ofhandles 40. Theclip 20 is used in conjunction with afastener 60 to press aheat sink 80 onto achipset 100 mounted on amotherboard 90. A pair of throughholes 92 is defined in themotherboard 90 in the vicinity of two diagonally opposite corners of thechipset 100. Theheat sink 80 comprises abase 82 and a plurality ofparallel fins 84 extending upwardly therefrom. Two adjacentcentral fins 84 are substantially shorter than all remainingfins 84. A pair ofhorizontal ridges 86 is formed on lower portions of respective outmost faces of thecentral fins 84. Theridges 86 are parallel to each other and equidistant from thebase 82, and engage with thefastener 60. - The
clip 20 comprises a horizontalpressing section 22, and a pair ofspring arms 24 extending perpendicularly from opposite ends of thepressing section 22 respectively. Thespring arms 24 both extend generally upwardly, but in different directions from thepressing section 22. A difference in the said directions is approximately 90?. Ahook 28 is formed at a distal end of eachspring arm 24. Theclip 20 may be made of any elastically deformable material, such as hardened spring steel wire. A cross section at any point along theclip 20 is generally circular. - The
fastener 60 is integrally made of plastic or other suitable material. Thefastener 60 comprises a centralbasal body 62, twopressing portions 64, and a pair ofcatches 66. Eachpressing portion 64 extends upwardly from thebasal body 62, then horizontally outwardly, and then downwardly. Eachpressing portion 64 thus has an inverted U-shape, enabling it to accommodate thecorresponding fin 84 having theridge 86. Eachcatch 66 extends inwardly from a free end of eachpressing portion 64, for engaging with theridge 86 of thecorresponding fin 84. Alongitudinal notch 68 is defined in a bottom surface of thebasal body 62. Thenotch 68 has a generally arcuate profile, and facilitates abutting of thepressing section 22 of theclip 20 against thebase 82 of theheat sink 80. - The two
handles 40 are identical. Referring to FIG. 2, eachhandle 40 is integrally made of plastic or other suitable material. Thehandle 40 comprises arectangular base plate 42 and twofixing blocks 44 formed on a main surface of thebase plate 42. An opposite surface of thebase plate 42 is for manual pressing during operation. Theblocks 44 are formed at two diagonally opposite comers of thebase plate 42 respectively, and extend toward each other along a pair of orthogonal edges of thebase plate 42. Agroove 48 is defined in an inner side surface of eachblock 44. Eachgroove 48 is parallel to thebase plate 42, and the twogrooves 48 are equidistant from thebase plate 42. - Referring also to FIG. 3, in assembly, each handle40 is mounted to the
clip 20 at a junction of thepressing section 22 and onespring arm 24. Thegrooves 48 of thehandle 40 respectively accommodate part of thepressing section 22 and part of onespring arm 24. Then, the combinedclip 20 and handles 40 is placed onto theheat sink 80. Thepressing section 22 of theclip 20 is accommodated in a space (not labeled) of theheat sink 80 between the twocentral fins 84 having theridges 86. Then, thefastener 60 is attached to theheat sink 80. Thebasal body 62 is accommodated in the said space between the twocentral fins 84. Thepressing portions 64 of thefastener 60 are pressed downwardly until thecatches 66 of thefastener 60 snappingly engage with theridges 86 of theheat sink 80. Thefastener 60 at thenotch 68 abuts against thepressing section 22 of theclip 20. Thus thefastener 60 is secured onto theheat sink 80, and prevents theclip 20 from falling out of theheat sink 80. - The
heat sink 80 together with the clip assembly is then placed onto thechipset 100 on themotherboard 90. Onehandle 40 is depressed so that theproximate hook 28 of theclip 20 is extended through the corresponding throughhole 92 of themotherboard 90. The saidproximate hook 28 is thus loosely engaged with a bottom surface of themotherboard 90. Then, theother handle 40 is depressed so that theother hook 28 of theclip 20 is extended through the other throughhole 92 of themotherboard 90. The saidother hook 28 is thus resiliently engaged with the bottom surface of themotherboard 90, and the saidproximate hook 28 simultaneously becomes resiliently engaged with the bottom surface of themotherboard 90. Thus, theheat sink 80 is pressingly and securely attached to thechipset 100 by theclip 20. - It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present example and embodiment are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
