A number of screws and the through hole are used to fix the radiator on the heating electronic component of circuit board. A guidance-component is vertically fixed on the fixed-arm against the through hole, which includes a sleeve to contain the screws and the fixed-part that links the sleeve and locks the fixed-arm, thus it makes the crews keep vertical to the fixed-arm and circuit board, achieving accurate lock and avoiding damage to other components.
Description
[technical field]
The present invention relates to a kind of fixture, be meant a kind of fixer for heat radiator that is used for radiator is fixed to heat-generating electronic elements especially.
[background technology]
As everyone knows, electronic component such as central processing unit produces a large amount of heat in running.For preventing that thereby this heat-generating electronic elements from causing its temperature rising to cause its fluctuation of service because of the accumulation of heat, this electronic component need install a radiator additional usually with auxiliary its heat radiation, for this radiator is closely contacted with electronic component, also often need a fixture that this radiator fixedly is close to electronic component.
Generally, screw is often used as fixture radiator is fixed on the circuit board at electronic component place, thereby radiator and electronic component are close to.Some screws pass the base of radiator or be fixed in the perforation of the fixed head correspondence on this radiator and circuit board on corresponding through hole, and then lock together with the backboard of circuit board below, dispel the heat thereby this radiator is fixed on the electronic component.Usually, need in the installation process by electric screw driver screw lock screw, yet, use in the process of electric screw driver, the directivity of artificial difficult its power of control, then electric screw driver to the active force of screw be difficult for well remaining on screw axially on, thereby make screw depart from the screw of backboard, cause screw damage backboard, even cause backboard to break.So this fixer for heat radiator needs further to optimize.
[summary of the invention]
In view of this, be necessary to provide a kind of safe fixer for heat radiator that locks.
A kind of fixer for heat radiator, comprise some fixed arms that are bonded to radiator, each fixed arm is provided with a through hole, some screws cooperate with this through hole this radiator is fixed on the heat-generating electronic elements of being located at circuit board, on this fixed arm to should vertically being provided with a director element in the through hole, this director element comprises that the sleeve of ccontaining this screw reaches the fixed part of this fixed arm of clip that is connected with this sleeve, described fixed part comprises two fixing feet, this two fixing feet is positioned the relative both sides of said fixing arm, thereby this screw is kept perpendicular to this fixed arm and circuit board when locking.
Compared with prior art, above-mentioned director element is vertically positioned on the said fixing arm, and above-mentioned screw is placed in the sleeve of this director element, thereby keeps vertical this fixed arm of this screw and realize accurate locking, avoids damaging other elements.
With reference to the accompanying drawings, the invention will be further described in conjunction with the embodiments.

[embodiment]
See also Fig. 1, one fixture comprises two fixed mounts 20, the plurality of fixed part 30 that cooperates with this fixed mount 20 that is fixed to a foot of radiator 10 both sides and is positioned director element 40 on this fixed mount 20, thereby radiator is fixed to circuit board (figure does not show) and contacts heat radiation with electronic component (figure does not show).
This foot of radiator 10 roughly is square, and it has the end face that is used for the bottom surface that contacts with electronic component and is used to be provided with fin (figure does not show) or other heat dissipation elements.
This two fixed mount 20 is fixed to the relative both sides of above-mentioned base 10 by screw.Each fixed mount 20 roughly is " C " shape, it comprise one be fixed to the bar shaped main part 210 of base 10 both sides, from outward extending two fixed arms 230 of these main part 210 opposite ends.The proximal end place of each fixed arm 230 is provided with a through hole 231.This fixed arm 230 is provided with two locating grooves 233 in the relative both sides of through hole 231, is used for above-mentioned director element 40 is positioned this fixed arm 230.
Each fixture 30 comprises a screw 310 and is placed on spring 320 on this screw 310.This screw 310 comprises a bar portion 313, from these bar portion 313 two ends upwards, the bigger less extension 315 of head 311, diameter of diameter that extends of one downwards.The terminal threaded portion 317 of further extending downwards of this extension 315, the backboard (figure does not show) that is used to lock and is positioned at the circuit board opposite side.This spring 320 is placed in the bar portion 313 of these head 311 belows.
See also Fig. 2 and Fig. 3, each director element 40 is one-body molded by plastic material, it comprises a fixed part and from the upwardly extending cylindrical sleeve 410 of this fixed part one, this fixed part comprises a pedestal 430 and two fixing feet 450 of extending from these pedestal 430 relative both sides one downwards.This pedestal 430 roughly is a truncated rectangular pyramids body, and it comprises four sidewalls (not indicating) that a middle part is provided with the base plate 431 of perforate 433 and extends upward and connect above-mentioned sleeve 410 from these base plate 431 four side one.Certainly, this pedestal 430 can not established sidewall, and promptly sleeve 410 directly extends vertically upward from this base plate 431.The diameter of this perforate 433 greater than the diameter of above-mentioned screw 310 extensions 315 less than the diameter of bar portion 313.This sleeve 410 around have with above-mentioned perforate 433 together with room 411 (as shown in Figure 1), with ccontaining above-mentioned fixing piece 30.The diameter of this room 411 is greater than the diameter of these screw 310 heads 311.This two fixing feet 450 is corresponding with two draw-in grooves 233 of said fixing arm 230, and its end is formed with the two relative barbs 451 that are used for this fixed arm 230 of snapping.
See also Fig. 4 and Fig. 5, during assembling, the through hole 231 of base plate 431 corresponding said fixing frame 20 fixed arms 230 of each director element 40 pedestal 430 and sit and to place this fixed arm 230 upper surfaces, 433 pairs of the perforates of this base plate 431 should through hole 231.Two fixing feet, 450 correspondences of director element 40 are positioned this through hole 231 both sides by two draw-in grooves 233 of this fixed arm 230, the lower surface of this fixed arm 230 of barb 451 butts of fixing feet 450.Thereby make this director element 40 be stable on this fixed arm 230 and perpendicular to this fixed arm 230.Each fixture 30 places in the sleeve 410 of this director element 40, its extension 315 passes the perforate 433 of holder 430 base plates 431, threaded portion 317 stretches out through hole 231, bar portion 311 and spring 320 blocks are vertically positioned on this fixed arm 230 thereby this screw 310 and this sleeve 410 and perforate 433 are coaxial and the accurate corresponding screw that is positioned at the backboard of circuit board opposite side on this base plate 431.By electric screw driver (figure do not show) act on screw 310 head 311 and in the screw with these screw 310 these backboards of locking, thereby radiator is fixed on the heat-generating electronic elements.
Above-mentioned director element 40 is vertically positioned on the fixed arm 230 of said fixing frame 20, above-mentioned fixing piece 30 is placed in the sleeve 410 of this director element 40, and its screw 310 is coaxial with this sleeve 410, thereby the screw of these screw 310 accurate corresponding circuits plate opposite side backboards and being locked in this screw is avoided because of the corresponding inaccurate backboard that damages with screw of screw 310.The base plate 431 of this director element 40 is sat and is placed on this fixed arm 230 in addition, the bar portion 313 of this screw 310 and spring 320 blocks are on this base plate 431, thereby when preventing to lock screw 310, because of this bar portion 313 and spring 320 and fixed arm 230 all for metal material produces wearing and tearing, also avoid causing the circuit board short circuit because of metal fragment that friction the produces circuit board that drops.
