Description
[technical field]
The present invention relates to the fixture that a kind of radiator is used, be meant a kind of especially in order to radiator is fixed to the backboard composite set on the motherboard.
[background technology]
Along with electronic industry constantly develops, the caloric value of computer system is increasing, and radiator has become the requisite heat dissipation elements of electronic component such as the interior central processing unit of computer system.Correspondingly, various fixtures also are widely used for radiator is fixed on the circuit board, and radiator can more closely be fitted on the electronic component, and this electronic component is dispelled the heat.Because the volume of radiator is increasing, it is also increasing that required button is held power, easily causes the circuit board distortion.For preventing the circuit board distortion, the intensity of a backboard with the intensifier circuit plate is installed on circuit board usually.
Illustrated in figures 1 and 2 is a kind of common fixture of the prior art.This fixture comprises a backboard 1 that is formed by the sheet metal integrated punching.The central authorities of backboard 1 are pressured dull and stereotyped 2, are the U-shaped shell fragment 3 that extends towards both sides at its four corner, and U-shaped shell fragment 3 is terminal for fastening the fastening breach 4 on the fastening projection 12 of radiator 10.Be provided with the brace 5 of being convenient to the application of force between the two U-shaped shell fragments 3 of backboard 1 both sides.
During fixed heat sink, fastening projection 12 correspondences that radiator 10 bottoms form are passed the perforation (not label) that motherboard 14 is preset, again this backboard 1 is attached to this motherboard 14 back sides, and fastening projection 12 correspondences that make radiator 10 are passed the fastening breach 4 of this backboard 1, at last nut 16 is spun on the fastening projection 12, thereby this backboard 1, radiator 10 and motherboard 14 are combined.But this type of backboard composite set can't make radiator rear panel 1 combine with motherboard 14 in advance, and packed and transported all need be separated, and also causes the user that the inconvenience of radiator is installed.
[summary of the invention]
In view of this, be necessary to provide a kind of can pre-assembled backboard composite set.
A kind of backboard composite set, comprise a backboard that is resisted against motherboard one side and pass backboard and the plurality of fixed post of motherboard, wherein each fixed leg comprises a junction, this connecting portion one end has a block end big than the connecting portion size, the other end is a clamping part, after described fixed leg passes backboard and motherboard, its clamping part and motherboard or backboard buckle, thus make backboard and motherboard be folded between block end and the clamping part.
A kind of backboard composite set, comprise that one is resisted against the backboard of motherboard one side and is located at plurality of fixed post on the backboard, wherein each fixed leg comprises a junction, this connecting portion one end has a block end big than the connecting portion size, other end extension is provided with some shell fragments, the free end of each shell fragment is provided with outer hangnail structure of opening, these hangnail structures and motherboard or backboard buckle.
Compared to prior art, utilize in the described backboard composite set fixed leg with backboard composite set predetermined fixed on motherboard, help packed and transported.In addition, an end of fixed leg be provided with clamping part or outside the hangnail structure of opening, help the backboard composite set and other elements are assembled fast.
With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.

[embodiment]
See also Fig. 3, backboard composite set 100 of the present invention comprises a backboard 110 and several fixed legs 120, wherein these fixed legs 120 can be clasped with motherboard 200 after passing backboard 110, thereby backboard 110 can be installed in advance the bottom surface of this motherboard 200 to increase the intensity of this motherboard 200.
Wherein, a central processing unit 210 is installed in this corresponding position, motherboard 200 top, on the motherboard 200 around the central processing unit 210 respectively correspondence offer a through hole 220, wear cooperation for fixed leg 120 correspondences.
This backboard 110 roughly is cross, it comprises that one is the butting section 1102 of square type and 1,102 four jiaos of four fixed arms 1104 that stretch out respectively and form from the butting section substantially, wherein the close end of each fixed arm 1104 is provided with a perforation 1108, wears cooperation for fixed leg 120 correspondences.For improving the elasticity of backboard 110, can offer a square aperture 1106 in 1102 middle parts in the butting section.In addition, this backboard 110 adopts the moulding of metal blank stamping-out, and covers elastic insulated thin layer of one deck such as rubber blanket 130 etc. on the surface that this backboard 110 and motherboard 200 attach, and uses for insulation and buffering.
See also Fig. 4 and Fig. 5, this fixed leg 120 comprises the connecting portion of a hollow, forms holes in the fixed leg 120 as perforation or blind hole (as shown in the figure for perforation time state), and the inner surface of fixed leg 120 relative these holes is attacked and is provided with screw thread.Be provided with in the bottom of fixed leg 120 and be hexagonal block end 1202 substantially, the size of block end 1202 is big than the size of this connecting portion, and this block end 1202 is greater than the diameter of the perforation 1108 on the backboard 110 to play spacing effect.In addition, be interval with four shell fragments 1204 at the top of fixed leg 120, and be provided with a clamping part 1206 at the free-ended outer surface of each shell fragment 1204.It is that clamping part 1206 is for being located at outer hangnail structure of shell fragment 1204 ends that these clamping part 1206 relative shell fragments 1204 have a gradient, insert in the through hole 220 on the motherboards 200 with guiding clamping part 1206, thereby and be clasped with motherboard 200 and realize the pre-assembling of backboard 110 and motherboard 200.During pre-the assembling, promote fixed leg 120 to make its shell fragment 1204 produce distortion and after passing perforation 1108 and the through hole 220 on the motherboard 200 on the backboard 110 successively, shell fragment 1204 recovers nature, make the clamping part 1206 at shell fragment 1204 tops and the periphery of the through hole 220 on the motherboard 200 be clasped, thereby backboard 110 can be fixedly mounted in the below of motherboard 200.
In a last embodiment, clamping part on the fixed leg 120 1206 relies on the strain of shell fragments 1204 to pass perforation 1108 on the backboard 110 and 220 backs of the through hole on the motherboard 200 successively and implements pre-assembling with motherboard 200 buckles; In contrast, can make clamping part 1206 on the fixed leg 120 rely on the strain of shell fragments 1204 pass through hole 220 on the motherboard 200 and 1108 backs of the perforation on the backboard 110 successively and with backboard 110 buckles, can implement pre-assembling equally, this moment, screw 330 will be from the block end 1202 screws in fixed legs 120.
Describe as seen from the foregoing description, fixed leg 120 make backboard 110 can predetermined fixed on motherboard 200, help packed and transported.Because backboard composite set 100 is with respect to motherboard 200 fix in position, when needs are installed radiator 300, only need make screw 330 pass radiator 300 and screw togather, just can easily radiator 300 be fixed on the motherboard 200 with the screw thread of fixed leg 120 inside.
