Description

Fastener of heat sink

[technical field]

The utility model is about a kind of fastener of heat sink, is meant especially a kind of heating radiator to be fitted tightly on the central processing unit surface, and assembles convenient and need not the fastener of heat sink of tool using.

[background technology]

Along with intensive day by day, the complicated development of integrated circuit of electronic component (particularly CPU), the heat of its generation increases severely thereupon.For this reason, selected heating radiator volume, the weight of industry also increases thereupon, the heating radiator holding unit is fastened the also corresponding raising of requirement of aspects such as strength and intensity, and therefore heating radiator being fastened on the electronic component well is problem extremely to be solved.

The Taiwan patent announcement discloses a kind of typical fastener of heat sink No. 270560, show as Fig. 1, comprise a pressure section 10 and the elastic arm 12 that extends obliquely from pressure section 10 two ends, the terminal extension downwards of elastic arm 12 is provided with a button arm 14, the appropriate location of this button arm 14 offers two openings 16, and the base of higher opening 16 extends upward a sheet metal 18, and as the point of application of instruments such as finger or bottle opener, lower opening 16 hooks connector trip 19.Yet this class fastener if pull sheet metal 18 with finger, very easily scratches finger because of careless manipulation in assembling and disassembly process; If pry open with bottle opener, then very easily to scrape the damage motherboard, even scratch peripheral electronic component because of careless manipulation, operation is absolutely unsafe.

There is the dealer to disclose another kind of typical fastener of heat sink No. 456586 in addition at the Taiwan patent announcement, show as Fig. 2, this fastener is formed by the rectangular one bending of a metal, it comprise an oppression department 10 ', extend at a certain angle at oppression department 10 ' two ends two elastic arms that are uneven in length 12 ', each elastic arm 12 ' bend out buckling parts 14 ', and buckling parts 14 ' be formed with hanging hole 16 '.During fastening, earlier a hanging hole 16 ' hook is located at connector one trip 19 ' on, again with the hand application of force press down long elastic arm 12 ', make another hanging hole 16 ' hook be located at another trip 19 of connector ' on, remove external force at last, by elastic arm 12 ' elastic restoring force make heating radiator fit tightly on CPU.Yet this class fastener of heat sink does not have tangible force application location, is fastening or unloading process application of force inconvenience; And when requiring fastening power big, the rigidity of this fastener must increase, and obviously effort is unrealistic with subordinate clinching tool.

Again just like United States Patent (USP) the 6th, the cam-type fastener that 061, No. 239 patent disclosed shows as Fig. 3, this fastener comprises two partly, one rubber-like long and thin metal band 10 ", this metal tape 10 " two ends form grab 12 ", but hook is located on the motherboard; and a cam-type is pulled body 14 ", rotation is articulated in metal tape 10 " middle part, rotate this and pull body 14 ", and its cam 16 " will compress heating radiator on heater element.Need not instrument when this fastener fastens, operate also safelyr, still, the pulling on body 14 " more firmly is articulated in metal tape 10 " of this fastener difficultly will be pulled body and metal tape dismounting; When heating radiator changed, the body of pulling that is difficult to the replacing different size provided different fastening power, need to change the variation that whole fastener adapts to heating radiator, thereby the only suitable a kind of heating radiator of this fastener, the application scenario is single, causes cost to increase, waste resource.

[summary of the invention]

The purpose of this utility model be to provide a kind of assemble convenient, safe, can adapt to different occasions, save cost and resource and need not the fastener of heat sink that tool using is installed.

The purpose of this utility model is achieved through the following technical solutions: the utility model fastener of heat sink comprises a main body and an operating body.This main body comprises the buckling parts that a body and two extends from these body two ends downwards; Be provided with two holding part in this body central authorities appropriate location, these holding part are connected on the body in conjunction with pin by one respectively.This operating body comprises that a rotating part and bends the rotary handle that forms from this rotating part one end; These rotating part central authorities are provided with a projection, form an embedding part respectively in the both sides of this projection, and this embedding part can be fastened in this holding part.Can pull this rotary handle makes this projection compress heating radiator on the CPU surface.

Compared with prior art, operating body of the present utility model is fastened on the main body by the holding part of C type, only need firmly spur this operating body can with this operating body and this body portion from, thereby replaceable different operating body cooperates different heating radiators, so that different fastening power to be provided, has the advantage that assembling is convenient, safe, be suitable for different occasions, saving cost and resource; Only need pull operating body in addition can be close to heating radiator on the heater element, has simple to operate and need not the advantage of tool using.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described.
