Description

The fixture of central controller seat and radiating seat

The utility model relates to a kind of jockey, is mainly used in the fixture that is connected the radiating seat on the central controller seat.

At present, the common radiating seat with a fan is fixed on the CPU seat (central controller seat), quicken the radiating effect of CPU, the dependence tolerance fit connects, often working as CPU thickness is negative common difference, and hook is when being plus tolerance, can form to collude the power of holding between fin and CPU and lower, again because the phenomenon of shrinkage and heat expansion, after experience a period of time, fixed relationship between radiating seat and CPU becomes looseningly because of the elastic properties of materials degree is weary, cause the heat conduction that influences between CPU seat and radiating seat, so, radiating efficiency will reduce or reduce gradually, and the heat that CPU produces can't effectively shed, and will CPU can not correctly be worked in the scope of setting.

The purpose of this utility model is the fixture that proposes a kind of central controller seat and radiating seat, borrow the effect of spring force, the mismatch error of making between central controller seat (CPU seat) and hook is compensated, guarantees that marriage relation does not between the two change because of expanding with heat and contract with cold.

The purpose of this utility model is achieved in that the fixture of a kind of central controller seat and radiating seat comprises central controller seat 4 and radiating seat 2, it is characterized in that: above radiating seat 2, be provided with a grip slipper 1, this grip slipper 1 comprises that flat board 101 and limit, two opposite sides with central through hole all are provided with vertical long buckling

foot

103a, 103b, 103c and 103d, short

buckling foot

104a, 140b, 104c and 104d respectively, are respectively equipped with hook portion 105a, 105b in long and short buckling foot lower end again; Radiating seat 2 four corners are respectively equipped with counterbore 202a, 202b, 202c and 202d; One spring 3 all is set in each counterbore again; Form the shoulder 402 that contacts with the hook portion 105a of long buckling foot on the central controller seat 4, and form and locate the hook portion 105b of the short buckling foot of

cave

203a, 203b, 203c and 203d withholding on the radiating seat 2.

Expose respectively outside counterbore 202a, 202b, 202c and the 202d of radiating seat the upper end of above-mentioned each spring 3.

Owing to adopt such scheme: make the heat conduction of central controller seat imitate stable.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model first embodiment exploded view.

Fig. 2 the utility model first embodiment schematic perspective view.

Fig. 3 the utility model first embodiment A-A profile.

Fig. 4 the utility model first Embodiment B-B profile.

Fig. 5 the utility model second embodiment schematic perspective view.

As shown in Figure 1, 2, the grip slipper 1 of first embodiment has a flat board 101, makes a through hole 102 at the central part of dull and stereotyped 101 end faces, as the air inlet of the fan 201 on the fan 2 on the existing radiating seat 2; Side dull and stereotyped 101 forms a plurality of vertically to long buckling

foot

103a, 103b, 103c and 103d, and short

buckling foot

104a, 104b, 104c and 104d, wherein the end of each long and short buckling foot extends in the length difference, but both inwardly all have hook portion 105a, the 105b of 90 ° of summaries of curving.

Again at four corners of radiating seat 2, it has counterbore 202a, 202b, 202c and the 202d that gos deep in the radiating seat 2, be provided with spring 3 in it,, be provided with

location cave

203a, 203b, 203c and 203d over against short

buckling foot

104a, 104b, 104c and 104d place at the side of radiating seat 2.

As Fig. 1, shown in 3, the counterbore 202a that elder generation inserts a correspondence respectively with an end of each spring 3,202b, in 202c and the 202d, hook portion 105b on each hinge buckling foot on its rear plate 101 faces cave, the location 203a on the radiating seat 2,203b, 203c and 203d and be pressed into, because the elasticity of short buckling foot, conflict at location cave 203a in the hook portion 105 of its front end, 203b, during the vertical wall of 203c and 203d, short buckling foot is supportted usefulness, the end of hook portion 105 is against on the vertical wall and is pushed, finally leave the moment of vertical wall in hook portion 105, each hook portion 105 enters cave, the location 203a of radiating seat 2 bottoms, 203b, location, state as shown in Figure 3 in 203c and the 203d.So, make the flat board 101 of radiating seat 25 grip slippers 1 be combined into one.

Shown in Fig. 1,4, the shorter buckling foot 104a of the vertical length of long buckling foot 103 is for long, and 4 of connecting plate 401 and CPU seats, separates formation one crossette 402 with the plate thickness that is slightly larger than hook portion 105a (4).Therefore, after the flat board 101 that long buckling

foot

103a, 103b, 103c and 103d outwards strut and the general be combined into one with radiating seat with each is pressed in connecting plate 401, discharge external force, can make 4 hook portion 105a respectively stretch into the bottom face of crossette 402, radiating seat 2 and CPU seat strike up partnership.Because spring 3 applies elastic restoring force all the time on dull and stereotyped 101, make connecting plate 401 have all the time to be pressed on tendency on radiating seat 2 bottom faces, thereby guarantee to do the excellent contact relation between the two; When the crossette 402 of long buckling foot at the CPU seat, short buckling foot and leave the cave, location and the button that can not influence long buckling foot is held effect.

As shown in Figure 5, second embodiment, be with the first embodiment difference: two relative long buckling foots, for example: 103a, 103b, 103c and 103d,

formation clasp

103a, 103b, 103c and 103d reach and respectively insert in two clasp 106a, 106b and 106c, the 106d with a U-shaped backstay 107a, 107b on about centre position, the outside; So can limit long

buckling foot

103a, 103b, 103c and 103d and outwards not strut, to guarantee CPU seat and the stable contact relation of radiating seat intercropping.
