Abstract
The invention provides a fastener and a radiating device using the same. The radiating device comprises a radiator having a base and a plurality of radiating fins extending upward from the roof of the base. The fastener comprises a middle part which spans the radiator and is pressed on the base. Both ends of the middle part can respectively form a pressing part bent downward or folded. The two pressing parts are pressed on the side edge of the base with one side adjacent to the middle part; and the terminal ends of the two pressing parts can respectively form an oppositely extended flexible arm. The two flexible arms rotate and bend relative to the middle part so as to make the middle part press the base downward, so that the radiator can not move horizontally, thereby ensuring the stable opposite position between the radiator and electronic components, ensuring the radiating effect, and not affecting the other electronic components.
Description
Technical field
The present invention relates to a kind of fastener, particularly a kind of being used for installs and fixes fastener to the heat-generating electronic elements with radiator.
Background technology
Develop rapidly along with computer industry, electronic component on the mainboard is more and more intensive, the heat that produces when operation is also more and more, except needs are given central processing unit (CPU) heat radiation of caloric value maximum, be necessary that also the electronic component around the centering central processor dispels the heat, as the north and south bridge chip.Therefore, the industry radiator that is sticked on the bridge chip of north and south usually dispels the heat, and by a linear fastener this radiator is applied compressing and make it closely be attached at the surface of chip.Yet in use, because make and rigging error, cause fastener that the less radiator that makes of the compressing power of radiator is slided with respect to the fastener along continuous straight runs, cause the dislocation of radiator and chip, thereby influence radiating effect, and may cause radiator to interfere on the mainboard other electronic component.
Summary of the invention
In view of this, be necessary to provide a kind of this radiator that prevents to produce the fastener of slide relative with respect to fastener and use the heat abstractor of this fastener.
A kind of fastener, be used for fixing a radiator, this radiator comprises that a pedestal reaches from the upwardly extending some radiating fins of this base top surface, this fastener comprises a pars intermedia, the two ends of this pars intermedia form a pressure section that is bent downwardly or bends respectively, this two pressure sections end forms an elastic arm that oppositely extends respectively, when this fastener is fixed this radiator, described pars intermedia strides across this radiator and is pressed on the pedestal, described two pressure sections are in the lateral edges that is resisted against this pedestal near a side of pars intermedia, and described two elastic arms are with respect to this pars intermedia rotation bending and make pars intermedia to this pedestal of lower compression.
A kind of heat abstractor, this heat abstractor comprises a radiator and a fastener, this radiator comprises that a pedestal reaches from the upwardly extending some radiating fins of this base top surface, this fastener comprises a pars intermedia, the pars intermedia of this fastener strides across this radiator and is pressed on the pedestal, the two ends of this pars intermedia form a pressure section that is bent downwardly or bends respectively, this two pressure section is resisted against the lateral edges of this pedestal in the side near pars intermedia, this two pressure sections end forms an elastic arm that oppositely extends respectively, and this two elastic arm is with respect to this pars intermedia rotation bending and make pars intermedia to this pedestal of lower compression.
The pressure section of this fastener inserts and puts this radiator from the relative both sides of this radiator, make this radiator to slide with respect to this fastener, thereby guarantee the stable of relative position between this radiator and fastener and the chip, guarantee radiating effect, and unlikely other electronic components are exerted an influence.

Embodiment
See also Fig. 1, heat abstractor for the embodiment of the invention, this heat abstractor comprises a fastener 10 and a radiator 20, this radiator 20 is used for heat-generating electronic elements (figure does not show) heat radiation on the mainboard (figure does not show), as the north and south bridge chip, this fastener 10 is used for this radiator 20 is fixed on this mainboard.This fastener 10 is the linear fastener that a bonding jumper is bent into, and therefore, this fastener 20 should adopt has better flexible material, as spring steel.This fastener 10 comprises the pars intermedia 12 of a linear; The two ends of this pars intermedia 12 form a pressure section 13 that is bowed downward to camber line shape, " C " shape as shown in fig. 1 respectively; These two pressure sections, 13 ends form an elastic arm 15 that oppositely extends respectively.This two pressure section 13 is positioned at same plane and with respect to these pars intermedia 12 symmetries, this pressure section 13 also can be other shapes of bending, as " V " shape broken line; This two elastic arm 15 is from the 13 terminal oppositely extensions respectively of two pressure sections.Each elastic arm 15 comprises a linear extension 153 and a clamping part 155 that is bent to form from these extension 153 ends, this extension 153 extends along the direction vertical with pars intermedia 12 obliquely from its corresponding pressure section 13 is terminal, make that the bearing of trend of this two extension 153 is intersected with each other, this two clamping part 155 is fastener shape and the free end that is formed at elastic arm 15.This two extension 153 and pressure section 13 can be with respect to the axle center rotation bendings of this pars intermedia 12; This elastic arm 15 also can not need clamping part 155, is directly pressed on the block (figure does not show) on the mainboard by the end of extension 153.
This radiator 20 comprises that a pedestal 22 reaches from the upwardly extending some radiating fins 25 of these pedestal 22 end faces, these radiating fins 25 are arranged along the lateral separation, thereby and form a groove 23 in the centre position of pedestal 22 vacancy, this groove 23 longitudinally runs through by this radiator 20 and radiating fin 25 edges and laterally is divided into two parts.
See also Fig. 2 and Fig. 3, during assembling, earlier this radiator 20 is sticked above the north and south bridge chip on mainboard, then this fastener 10 is longitudinally striden across this radiator 20, at this moment, the pars intermedia 12 of this fastener 10 is contained in the groove 23 and is pressed on the end face of pedestal 22, is resisted against the horizontal edge of pedestal 22 on the pressure section 13 of fastener 10 near a side of pars intermedia 12, in other words, this pedestal 22 is folded between two pressure sections 13.This two extension 153 is respectively to both lateral sides that should radiator 20; Please consult Fig. 4 simultaneously, two extensions 153 are exerted pressure downwards simultaneously its axle center around pars intermedia 12 is rotated in opposite direction and press close to mainboard, pars intermedia 12 also can produce downward compressing power to pedestal 22 simultaneously, in the clamping part 155 of this fastener 10 is buckled on the mainboard corresponding block or button hole, thus this radiator 20 is fixing.Simultaneously, the pressure section 13 of this fastener 10 also can also be resisted against pedestal 22 edges of this radiator 20 all the time along with extension 153 rotations, because the camber line of two pressure sections 13 part inserts and puts this radiator 20 from the relative both sides of this radiator 20, make that this radiator 20 can't be with respect to this fastener 10 along horizontal slip, thereby guarantee the stable of relative position between this radiator 20 and fastener 10 and the north and south bridge chip, guarantee radiating effect, and unlikely other electronic components are exerted an influence.
