[embodiment]

See also Fig. 2 to Fig. 4, the utility model buckling device of radiator 10 is used for a radiator 60 is fitted tightly to an electronic component 90 surfaces.Be equiped with fixedly module 80 in advance around this electronic component 90.But should be fixedly this radiator 60 of module 80 supports thereon, this fixedly module 80 4 corners upwards stretch out some button gripping arms 82, each is detained gripping arm 82 and is provided with a locking hole 84.This radiator 60 comprises with a pedestal 62 of electronic component 90 contacts and from these pedestal 62 upwardly extending some parallel radiating fins 64.The both ends of these pedestal 62 relative both sides are equipped with the inside and outside jack 66,67 that is parallel to each other, the oblique accommodation space 68 that forms down in radiating fin 64 two ends of radiator 60 relative both sides, this accommodation space 68 further extends vertically downward until linking to each other with internal plug seat 66 after extending to internal plug seat 66 tops.The button gripping arm 82 of this accommodation space 68 and fixing module 80 is corresponding and a little more than button gripping arm 82.

Buckling device of radiator 10 of the present utility model comprises a snap the line fastener 20 and leader 40.This snap the line fastener 20 is formed by metal wire bending, and its middle part forms the clamping part 22 of a Qian shape.These clamping part 22 mediad inner bendings form a clasp 24, and its two ends are earlier oblique extend in parallel down after again with downwards and slightly inwardly further extension and form inside and

outside kink

26,27 of different angles.These inside and outside

kink

26,27 ends bend inwards into inside and

outside contact pin

28,29 respectively.

This handle 40 can be installed up on this snap the line fastener 20, and it mainly comprises a levels operation portion 42, a stop section 44 and a junction surface 46.This stop section 44 is oblique parallel-segment of extending and can be affixed on the inside and

outside kink

26,27 of fastener 20 down from an edge of operating portion 42.This operating portion 42 extends a junction surface 46 vertically downward apart from the one determining deviation place, edge that extends stop section 44.These 46 inboards, junction surface stretch out a holding block 48, and this holding block 48 is closely inlayed to the clamping part 22 of this snap the line fastener 20 by interference fit, thereby clamping part 22 is fixed on the junction surface 46.

During assembling, earlier holding block 48 inlay cards at junction surface 46 are gone in this clamping part 22, so that this handle 40 is installed up on the snap the line fastener 20.At this moment, the parallel-segment of the clamping part 22 of fastener 20 and inside and

outside kink

26,27 is close to the

junction surface

46 and 44 inboards, stop section of this handle 40 respectively.Four buckling devices 10 after will making up again place 60 4 jiaos of ends of radiator respectively, inner fold 26 and corresponding accommodation space 68 are aligned, and inside and

outside contact pin

28,29 align respectively with corresponding inside and outside jack 66,67.Buckling device 10 is promoted in accommodation space 68, and inner fold 26 and stop section 44 just place accommodation space 68, and interior contact pin 28 inserts in the corresponding internal plug seat 66.Should outer kink 27 part parallel with inner fold 26 also place accommodation space 68, its part that continues extension downwards then is affixed on radiator 60 outsides, in the outer contact pin 29 insertion outer jacks 67.The radiator 60 that is equipped with buckling device 10 is placed fixedly in the module 80, and fit in electronic component 90 surfaces.The downward operating portion 42 of squeeze grip 40 makes clasp 24 fasteners in the locking hole 84 of fixing module 80.The inside and

outside kink

26,27 that makes snap the line fastener 20 that combines of clasp 24 and fixing module 80 deforms and then produces and acts on one on the radiator 60 and compress power, and radiator 60 is closely conformed to electronic component 90 surfaces.

Buckling device 10 of the present utility model is not limited in the above embodiments, its handle 40 also can adopt by 46 both sides, the junction surface flanging that respectively bends inwards out, and the clamping part 22 of this snap the line fastener 20 then can closely be installed up between this two flanging so that this handle is installed up to snap the line fastener 20.
