Description

Be used for assembling the fixedly fastener of heat abstractor

The utility model relates to a kind of fastener, particularly a kind ofly is used for assembling the fixedly fastener of heat abstractor.

Generally, the central processing unit of computer (Central Process Unit is hereinafter to be referred as CPU) can produce high temperature when computing, if its timely eliminating then can be able to not be influenced its performance, even burns, especially the arithmetic speed fast heat that CPU produced of healing is higher, and its influence is more remarkable; Therefore, any host computer all must be provided with heat abstractor to get rid of the heat that CPU was produced.

Generally, mainly be directly on CPU, to have the heat radiator of a plurality of fins, and fan is set on heat radiator with the mode setting that contacts for the arithmetic speed heat abstractor design of CPU faster; The most heat that is produced during the CPU computing is absorbed by heat radiator, and CPU then starts fan running simultaneously and blows heat radiator so that heat is got rid of when computing.

The relatively large circuit board type CPU of present Intel (INTEL) the above grade of PENTIUM II that company produced, be that this CPU is combined in the card casket, again CPU is loaded on the motherboard with upright state group together with the card casket, therefore also needs heat radiator and CPU to be fixed than the fastener of particular design.But the buckle structure that tradition is used for aforesaid heat radiator and CPU are fastened assembling is complexity very often, and its unhandy result tends to allow assembler's false touch be plugged in other electron component on the motherboard, and severe patient will cause the fault of machine; And too the buckle structure of complexity also can increase manufacturing cost, reduces the market competitiveness, and economy is not good.Therefore, the utility model is to be used for being improved in conjunction with the existing shortcoming of fastener of the CPU of the framework grades such as SLOT A of SOLT 1 framework of INTEL PENTIUM II and AMD ATHLON at aforementioned conventional.

Fundamental purpose of the present utility model is that a kind of fixedly fastener of heat abstractor that is used for assembling will be provided, and makes its loading and unloading more efficient, and the more traditional person of structure more simplifies and can reduce manufacturing cost.

The purpose of this utility model is achieved in that

A kind ofly be used for assembling the fixedly fastener of heat abstractor, it is characterized in that, mainly include:

One clamping element, be that opposite end at a mainboard body has extended a pinch respectively and formed the Jiong shape, the lower end of this two pinch is formed with bend respectively toward interior side direction, and wherein the relative dual-side of a pinch is equipped with a prominent axle respectively, and the lateral surface of an other pinch is provided with a protruding grain;

One control element, it has a press section, is extended with two parallel lever arms by this press section, and the width between this two lever arm is not less than the width of two pinches of aforementioned clamping element, and this two lever arm is respectively equipped with axis hole;

This clamping element is inserted between two lever arms of control element, and wherein two of this clamping element one pinch prominent axles pass the axis hole of control element two lever arms respectively, and another pinch one end of this clamping element is inserted in the bottom between control element two lever arms.

The relative both sides of this clamping element are respectively equipped with a plurality of outstanding laterally elastic strip bodies.

The elastic strip body of this clamping element is inclined.

The relative both sides of this clamping element are provided with side plate in the mode of one bending, mold this elastic strip body from this side plate in stamping forming mode.

Based on this, provided by the utility modelly be used for assembling the fixedly fastener of heat abstractor, it includes a clamping element and a control element; By this control element toward the top when cocked, can allowing wherein, a pinch flicks toward lateral direction, and when depressing, this pinch that outwards flicks is moved toward the below toward interior side direction when this control element, and and then make the edge of base that two pinches clamp heat radiator and CPU be button to consolidate shape.

The utility model is simple in structure, particularly its easy means by operating lever promptly can control intermediate plate to heat radiator and CPU grip or remove clamping, easy to use, quick, cost is low.
