Abstract

A buckling device for radiators comprises a buckling component, two operating bodies and a fixing component, the buckling component is formed by integrally bending a round metal wire rod and has a horizontal jacking part and two elastic arms that extend bended obliquely-upwards and perpendicularly to the jacking part and toward the two sides from the two ends of the jacking part respectively, and a clamping hook is formed at the tail end of the elastic arms; the operating bodies are made integrally from plastic materials and arranged respectively at the bending sites for the connections of the elastic arms and the jacking part of the buckling component, two fixing bumps are convexly provided equidirectionally perpendicular to the two adjacent side edges respectively on the one side face of the base body, and two clamping trenches are formed at the same latitude in the inner sides of the two fixing bumps respectively; the fixing component is used to pre-position the buckling component on the radiator.

Description

Buckling device of radiator

[technical field]

The utility model is about a kind of buckling device of radiator, is meant a kind of convenient, with low cost buckling device of radiator that can be positioned exactly on the radiator and fasten especially.

[background technology]

Along with the fast development of electronics and information industry, the frequency of various electronic components and the speed of service are also in continuous lifting.But the heat that high-frequency high-speed will make electronic component produce is more and more many, and temperature is also more and more higher, and the stability when the electronic component operation in serious threat in order to ensure the normal operation of electronic component energy, must in time be discharged a large amount of heats that electronic component produced.

Industry is current to be that a heat abstractor of being made up of radiator, fan and fastener is installed on the heat-generating electronic elements, so that reach the heat radiation purpose, wherein, this heat abstractor is by means of fastener radiator to be fixed on the heat-generating electronic elements so that heat is distributed fully when combining with heat-generating electronic elements.In this design, this fastener is formed by the bending of circular metal wire rod one, the arm that it has a horizontal pressure section and roughly oppositely vertical respectively bending is extended from these pressure section two ends, the end of each arm also extends a fastener portion, by the hook between fastener portion and associated component or the structure, radiator can be fitted tightly to the central processing unit end face.But, the too tiny and smooth surface of existing this fastener, hand very easily skids and the bad application of force in manipulating process, causes operating difficulties, is unfavorable for the installation of radiator.Related art in addition can be with reference to No. the 332721st, Taiwan patent announcement.

[summary of the invention]

The purpose of this utility model is to provide a kind of simple operation, button to keep steady admittedly and buckling device of radiator with low cost.

The purpose of this utility model is achieved through the following technical solutions: the utility model buckling device of radiator comprises a fastener, two operating bodies and a fixture, this fastener is formed by the bending of circular metal wire rod one, it has a horizontal pressure section and bends two elastic arms of extension to both sides obliquely perpendicular to pressure section respectively from these pressure section two ends, and the end of this elastic arm also is bent to form a grab; This operating body is integrated by plastic material, its adjacent both side edges place, matrix one side vertically is convexly equipped with a fixed block respectively in the same way, respectively form a draw-in groove at this two fixed blocks medial surface equal height place, this two operating body is installed in the bending place that the elastic arm of this fastener links to each other with pressure section respectively; This fixture is used for this fastener pre-aligned to radiator.

Owing to adopted technique scheme, the utility model buckling device of radiator to have simple operation, detained keep steady solid and advantage with low cost.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 3 is the three-dimensional combination figure of the utility model buckling device of radiator and associated component.

[embodiment]

See also Fig. 1, the utility model buckling device of radiator is used for a radiator 80 is fitted tightly to central processing unit 100 end faces, and it comprises a fastener 20, two operating bodies 40 and a fixture 60.This radiator 80 comprises a pedestal 82 and extends upward some radiating fins 84 of formation from this pedestal 82, and adjacent two radiating fins 84 that roughly are positioned at central authorities are arranged with one respectively outwardly and cooperate with fixture 60 and with fastener 20 pre-aligned barbs 86 to radiator 80 in its appropriate position, outside.

This fastener 20 is formed by the bending of circular metal wire rod one, it has a horizontal pressure section 22 and bends two elastic arms 24 that extend to both sides obliquely perpendicular to pressure section 22 respectively from these pressure section 22 two ends, and the end of each elastic arm 24 also is bent to form difference fastener grab 28 in the corresponding button hole 92 on circuit board 90.

See also Fig. 2, this operating body 40 is integrated by plastic material, this operating body 40 is installed in the bending place that the elastic arm 24 of this fastener 20 links to each other with pressure section 22, it has a rectangular base 42, vertically be convexly equipped with a fixed block 44,46 respectively in the same way at this adjacent both side edges place, matrix 42 1 sides, respectively form an elastic arm 24 and the draw-in groove on the pressure section 22 48,50 that is fastened on fastener 20 respectively at these two fixed blocks, 44,46 medial surface equal height places.

This fixture 60 is integrated by plastic material, and it comprises a main part 62, two elastic pressing parts 64 and two clasps 66.Wherein, the bottom of this main part 62 forms an arc that is used for propping up the pressure section 22 of fastener 20 and presses the face 68 that touches; This two elastic pressing part 64 forms from the upwards repeatedly vertical bending extension in the both sides, top of main part 62 respectively; This two clasp 66 is respectively from the end projection inwardly of this two elastic pressing part 64 and go out, so that the barb 86 on hook radiator 80 radiating fins 84 and this fastener 20 is pre-aligned on radiator 80.

Please continue with reference to figure 3, during assembling, the bending place that the first elastic arm 24 that respectively two operating bodies 40 is installed in fastener 20 links to each other with pressure section 22, by fixture 60 that this fastener 20 is pre-aligned to radiator 80 again, then, radiator 80 is placed central processing unit 100 surfaces together with buckling device, grab 28 fasteners of elastic arm 24 ends that make fastener 20 1 ends are in the button hole 92 of circuit board 90 1 sides, again pressing operation body 40 make the other end grab 28 fasteners of elastic arm 24 ends in the button hole 92 of circuit board 90 opposite sides, promptly finish the assembling of radiator 80.
