Abstract
The utility model relates to a fastener for a radiator, which is integrally formed by plastic materials. The utility model comprises an end cap, an elastic part, a rod body and a head; the elastic part is arranged on one end of the rod body, the elastic part which is arranged between the end cap and the rod body is a C-shaped structure, an opening of which faces downwards, and the other end of the rod body is provided with a head which is provided with a multi-layer annular sharp cone structure; the specific position of the rod body is further provided with a concave ditch which is used for embedding a braking tool.
Description
The utility model is relevant a kind of fastener of heat radiator, especially about a kind of fastener that heat abstractor can be fixed on the heat-generating electronic elements.
Now, the electronic product speed to introduce is very fast.The framework of central processing unit card casket, heat abstractor and the fastener in last generation can be referring to Fig. 1, and it is made of circuit board 1, CPU (be welded on the circuit board 1, figure does not show), casket shell 2, heat-conducting plate 3, heat abstractor 4 and fastener 5.CPU is close to heat-conducting plate 3, and fastener 5 then is fastened on heat abstractor 4 on the heat-conducting plate 3, conducts heat to heat-conducting plate 3 so that make heat abstractor 4 can in time disperse CPU, guarantees that CPU can work smoothly.But the heat that this CPU produces is to pass to heat-conducting plate 3 earlier, sheds after heat-conducting plate 3 is passed to heat abstractor 4 again, exists and reduces radiating effect at every adjacent space or other media of having between the two.Moreover heat-conducting plate 3 generally is an aluminum alloy materials, except that increasing technology and cost, also can cause overall weight to increase.In view of this, the new central processing unit card casket of releasing has been removed heat-conducting plate, yet this makes that undoubtedly existing fastener is not competent.Therefore, how to provide a kind of convenient and firm fastener of assembling, central processing unit card casket of new generation and heat abstractor etc. can be combined into one, real problem for needing to be resolved hurrily.
The purpose of this utility model is to provide a kind of fastener of heat radiator, by the design of this fastener, can easily heat abstractor and heat-generating electronic elements be closely linked.
The utility model fastener of heat radiator is one-body molded by plastic material, comprises an end cap, an elastic portion, a body of rod and a head.Elastic portion and end cap are positioned at an end of the body of rod, and this elastic portion is between the end cap and the body of rod, and it is downward opening C font structure, and the other end of the body of rod then is for having the head of multilayer ring-type pointed cone structure.This body of rod further offers chase on ad-hoc location, use for stop frock inlay card.
Owing to adopted such scheme, made the utility model fastener of heat radiator have easy to assembly, advantage of simple structure.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the isometric exploded view of existing central processing unit card casket, heat abstractor and fastener.
Fig. 2 is the isometric exploded view of the utility model fastener of heat radiator, heat abstractor, central processing unit card casket and stop frock.
The isometric exploded view of another embodiment of Fig. 3 the utility model fastener of heat radiator and other relevant co-operating member.
Fig. 4 is the zoomed-in view of the another design of the utility model fastener of heat radiator.
Now seeing also Fig. 2, is the isometric exploded view of the utility model fastener of heat radiator 50, heat abstractor 40, central processing unit card casket 10 and stop frock 30.Card casket 10 comprises circuit board 12 and housing 14, is provided with central processing unit 24 in the weldering of the zone line of circuit board 12, and circuit board 12 offers four perforation 22 near four corners of central processing unit 24.Housing 14 offers block button hole 18 at zone line and the position of corresponding perforation 22 is provided with four cylinders 16 on the cylinder 16, use for fastener 50 and wear and fasten (describing in detail after a while).In addition, on circuit board 12 and housing 14, be respectively equipped with for the member that fastens usefulness, so that circuit board 12 and housing 14 are combined.
During assembling, make fastener 50 pass through hole 48 on heat abstractor 40 pedestals 42 earlier, push the end cap 52 of fastener 50 then, make elastic portion 54 be compressive state and the chase 58 of the body of rod 56 is positioned at outside heat abstractor 40 pedestals 42 bottom surfaces.Then stop frock 30 is slipped into along the bottom surface of heat abstractor 40 pedestals 42, it is embedded in the chase 58, need not push the end cap 52 of fastener 50 this moment again, relies on the mode of stop frock 30 inlay card chases 58 can make elastic portion 54 be in compressive state.Successively four fasteners 50 are pressed in the through hole 48 of heat abstractor 40 pedestals 42, make elastic portion 54 be in compressive state by stop frock 30.Then the head 59 of four fasteners 50 is passed perforation 22 on the circuit board 12 and the block button hole 18 on the housing 14, and make multilayer ring-type pointed cone structure on fastener 50 heads 59 be embedded in the inwall of housing 14 block button holes 18.At last, remove stop frock 30, by the snap effect between multilayer ring-type pointed cone structure on the head 59 and housing 14 block button holes 18, and the elastic force of elastic portion 54, and make heat abstractor 40 and card casket 10 stablize fixing and possess suitable fastening strength.
Now seeing also Fig. 3, is another embodiment of the utility model fastener of heat radiator and the isometric exploded view of other relevant co-operating member.This fastener 50 ' can be the structure (consulting Fig. 2) of aforementioned fastener 50, also can be formation (being not offer chase on the connecting rod of buckle main body) as shown in the figure.This stop frock 30 ' is provided with the slightly flat board of ovalize at the one end, then is provided with the handle of convenient plug at its other end.Heat abstractor 40 ' offers shallow slot 47 in the appropriate position of the fin 44 ' of groove 46 ' both sides.During assembling, fastener 50 ' is inserted in the groove 46 ', push end cap 52 ', when the end cap 52 ' end face of fastener 50 ' during a little less than shallow slot 47, stop frock 30 ' is slipped into along the shallow slot on the fin 44 ' 47, preventing fastener 50 ' resilience, and make elastic portion 54 ' be in compressive state.As for the assembling process of after-stage, because of identical with aforementioned manner, this does not state in addition.
Because the fin of heat abstractor is closely arranged usually, and has quite height, therefore when pushing the end cap of fastener, often need extra frock to assist and carry out, very inconvenient in the assembling, for improving these inconvenience, can adopt mode as shown in Figure 4, promptly suitably increase the height of this fastener 50 " end cap 52 ", make end cap 52 " end face can surpass the top of fin in when assembling, to reach easy to assembly and to omit the effect of extra frock.
