Description

The fastener of heat sink structure

[technical field]

The utility model is about a kind of fastener of heat sink structure, particularly fastens and the fastener structures of removal about a kind of reach easily.

[background technology]

The high-tech electronic industry, become the main flow on the market in recent years, along with the computer universalness, many DATA PROCESSING all must be dependent on computer and accurately be finished rapidly, because CPU can produce high heat in the process of computing, for fear of the damage that causes element because of high thermal conductance, CPU is last can be provided with a fin, fin can go out the high heat conduction that CPU produced, and utilizes fan that heat is sent engine body exterior again.

The existing fastener 1 that is used for fixing CPU 3 and radiator 2 sees also shown in Figure 1ly, and this fastener 1 is made of a bolting element 11 and a sleeve pipe 12.

Bolting element 11, mainly be the head 111 that is provided with big footpath in upside, be provided with a pressing part 112 in the below of head 111, this pressing part 112 has extended a body of rod 113 downwards, the below of this body of rod 113 is provided with a threaded portion 114, makes and be arranged with a flexible member 115 on the body of rod 113.

Sleeve pipe 12, it is a hollow tube, this sleeve pipe 12 can be sheathed for bolting element 11, the below of this sleeve pipe 12 is a fit portion 121, one side of this fit portion 121 down extends the holding section 122 of a column, this holding section 122 is provided with a sagittate hook part 123, in the fit portion 121 of the in addition side of holding section 122, then be provided with a groove 124, wherein, has an elastic space 125 between this holding section 122 and the fit portion 121, can make this holding section 122 have elasticity by this elastic space 125, and this elastic space 125 can be established for a screw S spiral shell.

Existing fastener 1 is when implementing, see also Fig. 2, shown in 3, the support runners 21 of this radiator 2 is provided with fixing hole 22, this fixing hole 22 can be inserted in by the top for the fit portion 121 of the sleeve pipe 12 of fastener 1, and by the elastic space 125 of this fit portion 121, can make this holding section 122 be inserted in easily in the fixing hole 22, when the fit portion 121 of sleeve pipe 12 is inserted in the fixing hole 22, but the hook part 123 of this holding section 122 is hook root edges in fixing hole 22, the groove 124 of fit portion 121 then is fastened on the periphery of fixing hole 22 just, then, be located in the elastic space 125 of sleeve pipe 12 with a screw S spiral shell, whereby, make hook part 123 break away from the root edge of fixing hole 22 because of being collided, cause coming off of sleeve pipe 12 to avoid this holding section 122; When these radiator 2 desires combine with circuit substrate P, be to support the top that runners 21 places circuit substrate P, and bolting element 11 is arranged in the sleeve pipe 12, and make the threaded portion 114 of this bolting element 11 pass circuit substrate P, be locked on again on the bolt element 41 of base 4, can finish the purpose that this radiator 2 combines with circuit substrate P.

Existing fastener 1; though can reach the purpose that radiator 2 combines with circuit substrate P by above-mentioned structure; yet; when this fastener 1 is desired to pull down on the support runners 21 of radiator 2; except wanting earlier bolting element 11 to be given the removal; must be again with screw S by unloading in the elastic space 125; again holding section 122 is pulled towards fit portion 121; make hook part 123 break away from the restriction of fixing hole 22; and the junction of this holding section 122 and fit portion 121 is a stress concentration point; this action makes holding section 122 and fit portion 121 produce the situation of fracture through regular meeting because of the application of force is improper, and then causes the damage of this sleeve pipe 12.

Because the fastener 1 of existing radiator 2 has the higher disappearance of dismounting formality spoilage complicated and sleeve pipe 12, so, will how to develop a fastener that simply combine and dismantle with circuit substrate that can make that radiator can be firm, reality is the problem of present electronics manufacturing solution that the person needs badly.
