Description
[technical field]
The present invention relates to a kind of buckling device, be meant that especially a kind of radiator with cooling electronic components is fixed in the buckling device on the circuit board.
[background technology]
General electronic component (as central processing unit) produces big calorimetric when moving, and itself and system temperature are raise, and too high temperature can make its runnability descend.For this reason, industry is installed radiator usually on electronic component, to discharge a large amount of heats that it is produced.Conduct heat fully for guaranteeing that radiator and electronic component can closely contact, need usually by the auxiliary radiator that fastens of buckling device.
As shown in Figure 6, disclose a kind of fastener of heat sink, it has: button bar 51, bend respectively at its two ends and to extend a button arm 511, with fastener accordingly on the projection 71 of the relative both sides of holder; And one action bars 53 place between the substrate 61 of this button bar 51 and radiator 60, make the tail end 531 of this action bars 53 be articulated in this button bar 51 belows, form a gangbar portion 533 in the stage casing of this action bars 53, after this gangbar portion 533 rotates an angle, but its this button bar 51 of outer rim 535 jackings, make the button arm 511 of these button bar 51 both sides be closely buckled in the projection 71 of holder 70 both sides, thereby radiator 60 is close on the chip.
Above-mentioned fastener must the first application of force press down shank 51 in when assembling, makes the button arm 511 at its two ends flexibly be buckled in the projection 71 of base both sides, dials and changes action bars 53, carries out further packing and operates to finish installation.In addition, triping when operation, dialling commentaries on classics action bars 33 earlier so that outside button bar 51 descends, relending assistant engineer's tool and will detain arm 511 and separate, just can unload radiator 60 with projection 71.Therefore the fastener of said structure must pull out the commentaries on classics action bars from a side when installation or removal, and easy and radiator electronic component interference on every side can not be adjusted fastener according to concrete needs and fasten dynamics.
[summary of the invention]
In view of this, be necessary to provide a kind of may command to fasten the buckling device of radiator of dynamics.
A kind of buckling device of radiator comprises one first fastener, one second fastener, and this first fastener, one end is to having the button pin, and this second fastener is arranged in the other end of first fastener, and its below is provided with the second button pin, also comprises an a connection piece and a screw rod spare; This connector is fixed on second fastener, offers a screw on it; This screw rod spare offers two thread segments and a no thread segment, wherein this no thread segment is located between two thread segments, this screw rod spare rotatably is located in the screw of fixture, described thread segment, no thread segment optionally cooperate with screw, with the bottom of adjustment screw rod spare and the relative position relation of first fastener.
This execution mode compared with prior art has following advantage: above-mentioned buckling device of radiator is connected with second fastener by connector, screw rod spare is installed in by the screw on the connector and makes its bottom compress first fastener on the connector, control then that the screw-in length of screw thread comes adjusting screw(rod) spare to press down first fastener on the screw rod spare, drive the height that second fastener moves up, thus the size of control fastening dynamics so that radiator closely contact with electronic component.
With reference to the accompanying drawings, the invention will be further described in conjunction with specific embodiments.
