[embodiment]
Figure 1 shows that a wherein embodiment of heat abstractor combination of the present invention, this heat abstractor combination comprises a fastener of heat sink 100, a holder 50 and a radiator 60, wherein, this fastener of heat sink 100 is used for cooperating with this holder 50, this radiator 60 is fixed on the holder 50, this holder 50 is arranged on a heat-generating electronic elements (figure does not show), and on every side, its two opposite sides are provided with projection 52 and 54.These radiator 60 middle parts are provided with two side by side storage tanks 62.
Please refer to Fig. 2, this fastener of heat sink 100 comprises: an elastic arm 10, an action bars 20, one movable fastener 30 and a rotating shaft 40.
This elastic arm 10 extends V-shaped structure obliquely from the middle part to both sides.Run through being provided with a breach 12 on this elastic arm 10, this elastic arm 10 can be cross-placed in two storage tanks 62 of this radiator 60 by this.The downward one of one end of this elastic arm 10 extends to form a button arm 14, and this elastic arm 10 and button arm 14 are to be made into integration by sheet metal, and this button arm 14 is provided with a button hole 142.These elastic arm 10 other end adjacents are provided with an a junction 16 and a top 18, and this connecting portion 16 is provided with two relative pivoted holes 162.
This action bars 20 comprises that a body 22 and extends upward the operating handle 24 of formation from body 22 upper ends, the upper end of this body 22 also is provided with a short slot 224, a pivoted hole 222 is established in the lower end of this body 22, this action bars 20 articulates by the pivoted hole on this pivoted hole 222 and above-mentioned rotating shaft 40 and the elastic arm 10 162, this action bars 20 can rotate around this rotating shaft 40, but the rotation of action bars 20 is subjected to the constraint of the top 18 of elastic arm 10, promptly the upper end of the body 22 of this action bars 20 can with these top 18 butts.
This activity fastener 30 portion thereon is provided with a perforation 32, be provided with a button hole 34 in its underpart, this perforation 32 can buckle from the periphery of action bars 20 on the short slot 224 of body 22, and the body 22 of action bars 20 and the connecting portion 16 of elastic arm 10 are housed in this perforation 32, so that make that when rotating operation bar 20 movable fastener 30 can movement therewith and do not interfere with action bars 20 and elastic arm 10.
Please refer to Fig. 1 and Fig. 2, when assembling radiator 60, can earlier radiator 60 be placed on the holder 50, then elastic arm 10 is cross-placed on the storage tank 62 of radiator 60, and will detains the button hole 142 of arm 14 and the button hole 34 of movable fastener 30 snaps onto on the projection 52,54 that is positioned at holder 50 opposite sides loosely.
Please refer to Fig. 3, at this moment, rotating shaft 40 is positioned at movable fastener 30 left sides, movable fastener 30 just can with projection 54 snappings of holder 50, then, rotate counterclockwise the operating handle 24 of action bars 20, the length of the movable fastener 30 that buckles with it owing to continuous rising of vertical position of short slot 224 on the action bars 20 is constant, therefore in the process of rotating operation bar 20, will produce the power of compression elasticity arm 10 connecting portions 16, and force elastic arm 10 generation elastic deformations and compress its radiator of suppressing 60.
Please refer to Fig. 4, when action bars 20 rotates to when rotating shaft 40 is overlapped with movable fastener 30, maximum elastic deformation takes place in elastic arm 10.Be rotated further action bars 20, the elastic deformation of elastic arm 10 reduces gradually, when action bars 20 forwards as shown in Figure 5 position to, and the body 22 of action bars 20 and top 18 butts of elastic arm 10, rotating shaft 40 is positioned at the right side of movable fastener 30, and short slot 224 is positioned at rotating shaft 40 tops.At this moment, elastic arm 10 still can produce enough deformation under the start of action bars 20 and movable fastener 30, makes fastener of heat sink 100 reach self-locking, and radiator 60 is firmly fixing, as shown in Figure 6.Simultaneously, because elastic arm 10 is cross-placed on the radiator 60 by breach 12, top 18 is positioned at outside the radiator 60, makes action bars 20 also be positioned at outside the radiator 60 when buckling state, thereby make radiator 60 in the breach 12 of elastic arm 10, fin is set, be more conducive to radiator 60 heat radiations.
Above-mentioned fastener of heat sink 100 only needs rotating operation bar 20 when fastening, required strength is little, has laborsaving and advantages of simple operation, and need not use any instrument.
