Description

The fixture of CPU radiating fin

[technical field]

The utility model relates to a kind of fixture of CPU radiating fin.

[background technology]

The high-tech electronic industry has become the main flow on the market in recent years, along with the computer universalness, many DATA PROCESSING all must be dependent on computer and accurately be finished rapidly, because CPU can produce high heat in the process of computing, for fear of the damage that causes element because of high thermal conductance, CPU is last can be provided with a fin, and fin can go out the high heat conduction that CPU produced, and utilizes fan that heat is passed out to engine body exterior again.

The fixture of general CPU radiating fin, as shown in Figure 1, be by CPU1, circuit board 2, fin 3, fixture 4 is formed, wherein CPU1 can weld the top of being located at circuit board 2 in advance, and the upper end of CPU1 all can set firmly fin 3, there are several radiators 31 these fin 3 tops, and the quadripolar corners at fin 3 is provided with perforation 32, the surface of this circuit board 2 is provided with jack 21 corresponding to perforation 32 places of fin 3, for fixture 4 eye-splices location, this fixture 4 is based on a press members 41, the sheathed flexible member 42 of these press members 41 meetings, the top of press members 41 is provided with a head 411, extends a cylinder 412 by the below of head 411, the end of this cylinder 412 is formed with the barb 413 of a taper, and its central authorities are provided with a profile groove 414.When combination, as shown in Figure 2, at first fin 3 is placed in the upper surface of CPU1, and make the perforation 32 around it corresponding with the jack 21 of circuit board 2, make the barb 413 of fixture 4 can penetrate fixing, the press members 41 of fixture 4 sheathed flexible members 42 earlier wherein, when flexible member 42 is sheathed on cylinder 412, make its perforation of passing fin 3 32, the chimeric again jack 21 that is fastened in circuit board 2, because of the perforation 32 of fin 3 and circuit board jack 21 its internal diameters less than the maximum outside diameter of barb 413, so, the profile groove 414 that the barb 413 of cylinder 412 ends is set, barb 413 can be divided into two and have the structure of elastic energy convergent-divergent, fix by barb 413 tight fin 3 is combined with the circuit board 2 that is provided with CPU1 that pressing of flexible member 42 can make press members 41, avoid fin 3 to come off, to reach the effect of certain heat radiation because of vibrations cause.

Therefore, usually making fin 3 is different producers with fixture 4, with fin 3, during the combining of CPU1 and circuit board, if the press members 41 of fixture 4 can be assembled in advance with flexible member 42, can save a large amount of built-up times, but, the internal diameter of flexible member 42 only is slightly less than the maximum outside diameter of barb 413 usually, because the setting of profile groove 414, barb 413 is divided into two has the structure of elastic energy convergent-divergent, make fixture 4 in the process of transporting, can make flexible member 42 break away from press members 41 because of collision, and the personnel of assembling can be used as defective products with the press members 41 of not sheathed flexible member 42 and abandoned at the scene, and then form meaningless waste.

Because the fixture of known CPU radiating fin is to the greatest extent imperfect, so, how to allow the flexible member of fixture not break away from briquetting machine, the problem that need solve for the present utmost point.

[utility model content]

The purpose of this utility model is to provide a kind of fixture of CPU radiating fin, and fin can closely be incorporated on the circuit board of CPU, and flexible member wherein is difficult for getting loose, and is convenient to assembling.

Based on above-mentioned purpose, the utility model provides a kind of fixture of CPU radiating fin, comprise press members and flexible member, the end of this press members is provided with a compression part, extend a cylinder by compression part, this flexible member is sheathed on this cylinder, a hook portion is then extended in the bottom of this cylinder, the bottom of this hook portion is circular-arc and is upside-down triangle shape by extending on two side direction of bottom, two sides on this hook portion are provided with tongue piece, be provided with groove between this cylinder bottom and hook portion, it is characterized in that: the side face of this cylinder is provided with several stop portions, and this flexible member is fastened in this stopper section.

The fixture of described CPU radiating fin is characterized in that: two sides of this hook portion upper end also can be provided with tongue piece.

The fixture of CPU radiating fin of the present utility model, the side face of mat cylinder is provided with several stopper sections, makes its restriction flexible member, is difficult for getting loose ease of assembly.

The fixture of CPU radiating fin of the present utility model, the other end of mat cylinder is established a hook portion, this hook portion is extended a tongue piece, the inner peripheral surface of the jack of circuit board is reclined mutually with tongue piece just, relend and help flexible member to make fin can closely be incorporated on the circuit board of CPU, avoid fin to come off, to reach the effect of certain heat radiation because of vibrations cause.

[embodiment]

Be the effect that can be easier to understand structure of the present utility model and can reach, cooperate graphic explanation now as back:

At first see also Fig. 3, the fixture 5 of CPU radiating fin of the present utility model, form by press members 51 and flexible member 52, the end of this press members 51 is provided with a compression part 511, extend a cylinder 512 by compression part 511, this flexible member 52 is sheathed on this cylinder 512, the side face of this cylinder 512 is provided with several stopper sections 513, a hook portion 514 is then extended in the bottom of cylinder 512, this hook portion 514 is that a bottom slightly is circular-arc and is upside-down triangle shape by extending on two side direction of bottom, two sides of hook portion 514 upper ends are provided with

tongue piece

515, and 514 of cylinder 512 bottoms and hook portions are provided with groove 516.

The inferior Fig. 4 that sees also when the press members in the fixture 5 51 makes up with flexible member 52, because the set stopper section 513 of cylinder 512 its side face appropriate locations in the press members 51 can be limited flexible member 52, drops its unlikely getting loose.See also Fig. 5 again, 6, when combination, same, at first fin 6 is placed in the upper surface of CPU7, and make the perforation 61 around it corresponding with the jack 81 of circuit board 8, make the hook portion 514 of fixture 5 can penetrate fixing, when fixture 5 when fin 6 is combined with circuit board 8, at first the hook portion in the press members 51 514 is passed the perforation 61 of fin 6, then insert again in the jack 81 of circuit board 8, at this moment, the perforation 61 of fin 6 and the jack of circuit board 8 81 its internal diameters are less than the horizontal maximum length of hook portion 514, but, because the groove 516 that cylinder 512 bottoms and hook portion 514 are set, can make hook portion 514 have the elastic energy convergent-divergent, and the internal diameter of the jack 81 of the perforation 61 of the external diameter of cylinder 512 and fin 6 and circuit board 8 is worked in coordination, when hook portion 514 barbs during in jack 81 root edges of circuit board 8, jack 81 inner circumferential surface of circuit board 8 recline mutually with tongue piece 515 just, the hook portion 514 that can make press members 51 by pressing of flexible member 52 closely combines fin 6 fixing with the circuit board 8 that is provided with CPU7 again, avoid fin 6 to come off, to reach the effect of certain heat radiation because of vibrations cause.

In sum, the fixture of CPU radiating fin of the present utility model is by the design of a stopper section, and can improve the shortcoming that press members and flexible member come off easily, and the fixture of commonly using CPU radiating fin has the effect of enhancement.
