Description

Fastener of heat sink

[technical field]

The utility model is about a kind of fastener of heat sink, is meant little, the easy accessibility of a kind of operating physical force especially, and detains the solid fastener of heat sink that keeps steady.

[background technology]

Along with vigorously developing rapidly of electronic industry, the large scale integrated circuit technology is constantly progressive, the integrated level of computer-internal electronic component is more and more higher, the speed of service is also more and more faster, the release of high-frequency high-speed processor is accelerated day by day, but, the high-frequency high-speed operation will make that the caloric value of electronic component is increasing, distribute if heat is untimely, then will cause the electronic component internal temperature more and more higher, have a strong impact on the stability of electronic component operation, nowadays heat dissipation problem has become a key factor that influences the computer run performance, also becomes the bottleneck of high speed processor practical application.

Only rely on now the heat radiation of electronic component self can not satisfy the demand of practical application fully, for this reason, industry installs a radiator additional on the heat-generating electronic elements surface usually and comes auxiliary heat dissipation, and for radiator is firmly closely contacted with heat-generating electronic elements, need radiator be pressed on the heat-generating electronic elements surface by a fastener in addition, technology early is to adopt screw to pass corresponding perforations on radiator and the circuit board and radiator is closely contacted with electronic component, but quite inconvenience of screw locking dismounting, and if the excessive circuit board that causes easily again of the local application of force is out of shape the application of fading out gradually.Linear fastener has appearred again subsequently, adopt the bending of metal wire rod one to form, mostly be " Z " font greatly, its middle part is pressed between the groove of radiator heat-dissipation fin, socket (connector is replaced at two ends, projection below or other location division of both sides down together), still, linear element is very thin, do not have and control the position, operation is inconvenience quite, and the assembling process difficulty is big, simultaneously, thickness at different occasion wire rods is difficult for grasping, if wire rod is thinner, fastening strength is not enough, if wire rod is thicker, can increase operating physical force again, thereby,, be not used usually as for saving space etc. if not special occasions.

The more employing of industry fastener of heat sink as shown in Figure 1, this fastener is a two-piece type, comprise a body 100 and an operating body 200, body 100 comprises a recessed pressure section 120 and the downward buckling parts 140 that extends of one end bending, the mode that operating body 200 wears by notch 220 is movably attached to an end of body 100, one end of body 100 and operating body 200 is equipped with opening 160,240, during assembling, opening 160 with buckling parts 140 is socketed on the projection 520 of socket 500 1 sides earlier, and pressure section 120 is pressed in the groove 320 of radiator 300 radiating fin central authorities, controlling operating body 200 and pressing down is socketed on the projection 520 of socket 500 opposite sides its opening 240, this fastener is compared prior art to be had than much progress, but in the also undeniable assembling process, the fastener start need be finished in pressing down the operating body process and overlap the action of receiving on the projection, operation easier is big, control inconvenience, and the locking of fastener normally relies on the elasticity of body 100, assemble the easy escape in back and radiator 300 is separated with heat-generating electronic elements 400, and cause serious consequence, and also need during dismounting firmly same.

Therefore, design that a kind of operating physical force is little, easy accessibility, fastener of heat sink that fastening is firm will be assembled computer to the dealer that big convenience is provided.

[summary of the invention]

The purpose of this utility model is to provide a kind of fastener of heat sink, is meant especially that a kind of operating physical force is little, easy accessibility and fasten firm fastener of heat sink.

The purpose of this utility model realizes by following technical proposal:

The utility model fastener of heat sink comprises a fastener main body and an executive component, this fastener main body has the horizontal body portion that establishes bayonet socket and notch, these body two ends respectively connect a button pin, this executive component is positioned at fastener main body below and articulates with the fastener main body, it is curved recessed, free end is upturned after passing the notch of body, and elastic fastening hook is established in the end, can be buckled in the bayonet socket of body.

Only need press down during the assembling of the utility model fastener of heat sink in the bayonet socket that snaps in body after executive component overlaps the grab that is connected with two shell fragments on it and get final product, inwardly push two shell fragments during dismounting, the i.e. escape from the bayonet socket of body of the grab of executive component then, and the pressure section that makes executive component leaves radiator, and disassembly process is convenient, fast.
