Description
[technical field]
The utility model relates to a kind of fixture, especially relates to a kind of fixer for heat radiator that is used for radiator is fixed on the elements such as central processing unit.
[background technology]
Flourish along with electronic industry, the large scale integrated circuit technology is constantly progressive, and the integrated level of computer-internal electronic component is more and more high, and the electronic component speed of service is also more and more fast, and the release of high-frequency high-speed processor is accelerated day by day.Yet the high-frequency high-speed operation will make that the caloric value of electronic component is increasing, distributes if heat is untimely, will cause the electronic component internal temperature more and more higher, has 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.
Now only rely on the heat radiation of electronic component self can not satisfy practical application request fully, for this reason, industry installs a radiator additional on the heat-generating electronic elements surface usually and comes auxiliary heat dissipation.For radiator is firmly closely contacted with heat-generating electronic elements, need in addition radiator to be pressed on the heat-generating electronic elements surface by a fixture.
Technology early is to adopt screw to pass corresponding perforations on radiator and the circuit board and make radiator fix and closely contact with electronic component, but the screw locking makes very inconvenience of operation, and easily causes circuit board distortion, the application of fading out gradually because of the local application of force is excessive.Occurred again being bent into roughly the fastener that is " M " shape by the metal lamellar body thereupon.These fastener central authorities are a pressure section, and the bending of pressure section two ends extends to form two buckling partss.Pressure section is closely against on the radiator, and buckling parts can with connector or fixedly module be interlocked, thereby radiator fixed and makes the surface of itself and electronic component fit tightly.Compare with the screw locking, use this fastener to simplify disassembly process, packaging efficiency increases, but still needs tool using usually when fastening, and it is very not convenient to operate yet.
So, must provide a kind of easy to operate fixer for heat radiator, to promote packaging efficiency.
[summary of the invention]
The utility model mainly is for a kind of easy to operate fixer for heat radiator is provided.
Fixer for heat radiator of the present utility model comprise vary in length operating body, the piston body that can in operating body, move, be set in elastomer on the piston body, be subjected to the buckling body and the fixed leg of piston body and elastomer control.When operating body length increased, piston body was towards spurring buckling body away from the fixed leg direction, and buckling body is buckled on the fixed leg, and elastomer is subjected to the extruding of buckling body and operating body and produces elastic potential energy.When operating body length was reduced, elastomer discharged elastic potential energy and the push card button is got back to the home position, removed the fastening between buckling body and fixed leg.
In the fixer for heat radiator of the present utility model, utilize the length of operating body to change the piston type produced and move and realize the buckle between buckling body and fixed leg or remove buckle, convenient to operation.
Below in conjunction with accompanying drawing the utility model fixer for heat radiator is described in further detail.

[embodiment]
Please referring to Fig. 1 to Fig. 5, the utility model fixer for heat radiator is to be used for a radiator 70 is navigated to processor 60 surfaces on the circuit board 50, makes radiator 70 quickly the heat on the processor 60 be conducted out.This fixer for heat radiator comprises operating body 10, piston body 20, elastomer 40 and the buckling body 30 that can be fastened togather with the fixed leg 58 that stretches out on the circuit board 50.
Offer the opening 52 of at least two symmetries on the circuit board 50 around processor 60.Fixed leg 58 is to extend and pass opening 52 on the circuit board 50 from a stiffener (not label).Certainly, fixed leg 58 also can be directly to extend from circuit board 50.Offer the draw-in groove 582 that can engage on the fixed leg 58 with buckling body 30.Radiator 70 comprises base 72 and the fin 73 that extends from base.Be provided with the through hole 74 that runs through radiator 70 bases 72 corresponding to fixed leg 58 on radiator 70 bases 72.
Operating body 10 is a cylinder, and it is divided into a stationary part 12 and a rotation section 14 by an arcwall face.Offer an axis hole 16 along axis in the operating body 10 and reach a notch 18 that is communicated with and is positioned at stationary part 12 with axis hole 16.14 outsides, rotation section are provided with one handle 142.Rotate described handle 142 and slided along described arcwall face in rotation section 14, and change the entire length of operating body 10.
Piston body 20 can be located in the axis hole 16 of operating body 10 and extend in the notch 18 of operating body 10.One end of piston body 20 is integrally formed with a stop section 22, and contiguous the other end then offers a groove 24.Stop section 22 is supported and is terminated on operating body 10 rotation sections 14.40 on elastomer is set in the groove 24 of described piston body 20.
Buckling body 30 comprises that being located at least two in radiator 70 through holes 74 detains arm 32.Described buckling body 30 1 ends are set in the groove 24 of piston body 20.Each button arm 32 is provided with grab 322 at the end away from piston body 20.Also outwards be provided with protuberance 324 in the middle of the button arm 32.
During use, each fixture is located in respectively in the through hole 74 of radiator 70 bases 72.Please be simultaneously referring to Fig. 3, when fixer for heat radiator did not fasten with fixed leg 58, operating body 10 had shortest length, and its stationary part 12 fits together appositely with rotation section 14.Elastomer 40 in the raw.The protuberance 324 in buckling body 30 outsides is between radiator 70 bases 72 and circuit board 50.
Rotate described handle 142, to be the center with piston body 20 rotate and be subjected to displacement along the length direction of operating body 10 along arcwall face for 14 of rotation sections, moves in operating body 10 towards the direction pulling piston body 20 away from circuit board 50 simultaneously.Piston body 20 drives buckling body 30 simultaneously and moves towards the direction away from circuit board 50.Operating body 10 when it reaches maximum length, protuberance 324 holdings of buckling body 30 in the through hole 74 of radiator 70 (please referring to Fig. 5).At this moment, buckling body 30 moves inward owing to being squeezed, and makes grab 322 fasteners in the draw-in groove 582 of fixed leg 58.The displacement that buckling body 30 takes place towards operating body 10 directions makes elastomer 40 be subjected to the extruding of buckling body 30 and operating body 10 and strain takes place, with the issuable impact of buffering vibration.
During dismounting, only need turning handle 142 to make operating body 10 be returned to shortest length.Elastomer 40 discharges its elastic potential energy, towards circuit board 50 direction push card buttons 30, make the protuberance 324 of buckling body 30 skid off the through hole 74 of radiator 70 and between radiator 70 and circuit board 50, buckling body 30 is towards circuit board 50 directions pulling piston body 20 simultaneously.The button arm 32 of buckling body 30 opens owing to the power of being squeezed no longer and make that grab 322 looses on it from the draw-in groove 582 of fixed leg 58.
