Description

Buckling device of radiator

The utility model is about a kind of buckling device of radiator, particularly can combine in advance and buckling device of radiator fixed thereon with radiator about a kind of.

Usually the heat abstractor combination of adopting for the central processing unit (CPU) heat transmission mainly comprises a radiator and buckling device, wherein this buckling device is made of a pressure section and the arm that extends obliquely respectively along these pressure section two ends, the end of each arm extends a snapping portion downwards, offer button hole in the snapping portion, by being clasped between the projection on button hole and the associated component (as connector etc.), just radiator can be closely adhered on the central processing unit end face.But this buckling device separates with radiator, all quite inconvenience in packing, transportation or use, and this buckling device also has the installing risk of wrong (as reversed left to right etc.).The technology of relevant common employing in addition also can be with reference to United States Patent (USP) the 5th, 602, and 719,5,600, No. the 84207615th, 85214941 and 86213035, No. 540 and Taiwan patent application etc.

Therefore, how providing a kind of can combine and buckling device of radiator fixed thereon in advance with radiator, is problem to be solved in the utility model.

The purpose of this utility model is to provide a kind of and can combines in advance and buckling device of radiator fixed thereon with radiator.

For achieving the above object, the utility model has adopted following technical scheme: the utility model buckling device of radiator is made up of two buckling pieces, and each buckling piece comprises a clinching body and two buckling bodies.This clinching body two elastic portion of having a pressure section and extending obliquely along these pressure section two ends wherein, the end of this two elastic portion extend horizontally away the holding section respectively.The lateral border of this pressure section extends earlier first extension vertically downward, the root edge of this first extension further extend horizontally away second extension inwardly, the two ends of this second extension upwards vertically extend a catch respectively, the central authorities of the pressure section and second extension offer a punching respectively, and the medial margin of this punching tiltedly stretches out a card.Each buckling body has a press section, a snap-latch piece and a cramp, and the position of corresponding clinching body holding section forms a draw-in groove that supplies this holding section to wear on this snap-latch piece.

Compared with prior art, the utility model buckling device of radiator is installed with respectively in the elongated slot and vertical trench of radiator by card and catch, buckling device and radiator are combined in advance, and therefore packing, transportation and use are all quite convenient, and install wrong risk.

Below in conjunction with drawings and Examples the utility model is specifically described:

Fig. 5 is the three-dimensional combination figure of the utility model buckling device of radiator and associated component.

See also Fig. 1, the utility model buckling device of radiator 1 is fastened on two stuck-modules 40 by installing, and it can closely fit to radiator 20 central processing unit 30 end faces.This radiator 20 has a pedestal 22 and some radiating fins of being located on these pedestal 22 end faces 24, the opposite end portion of this pedestal 22 is not provided with radiating fin and directly exposes end face, and its position at contiguous fin 24 is in upper and lower surface and offers an elongated slot 26 respectively, and offers two vertical trench 28 of the specific range of being separated by in the middle.Each stuck-module 40 has a supplementary wall 42 of extending, the two opposite end walls 44 that extend from supplementary wall 42 two ends up inwardly, an and base 46 that links the bottom of this supplementary wall 42 and this end walls 44, this supplementary wall 42, end walls 44 and base 46 define the end that a space can ccontaining radiator 20 pedestals 22 jointly, in addition, the apical margin of each end wall 44 projection 48 that extends outwardly out respectively.

Please together consult Fig. 2, this buckling device 1 is made up of two buckling pieces 10, and this two buckling piece 10 is placed on respectively on the both ends of radiator 20.Each buckling piece 10 comprises a clinching body 12 and two buckling bodies 16, and this two buckling body 16 is bonded on the two ends of this clinching body 12 respectively.This clinching body 12 has a pressure section 122 and is positioned at the two elastic portion 124 at pressure section 122 two ends, this two elastic portion 124 is extended obliquely respectively by the two ends of pressure section 122 and forms and its end extend horizontally away a holding section 126 respectively, holding section 126 offers a groove 128 at lengthwise to central authorities, and the tip designs of holding section 126 becomes barb-like and form a location notch 130 respectively in both sides.Pressure section 122 and partly the medial margin of elastic portion 124 extend a flanging 132 that is used for strengthening the structural strength of clinching body 12 vertically upward.The lateral border of pressure section 122 extends earlier first extension 134 that pedestal 22 end faces with radiator 20 connect vertically downward, the root edge of first extension 134 further extend horizontally away and pressure section 122 parallel relative second extensions 136 that connect with pedestal radiator 20 22 bottom surfaces inwardly, the two ends of second extension 136 upwards vertically extend a catch 138 respectively, this two catch 138 is installed with respectively in two vertical trench 28 of radiator 20 pedestals 22, can prevent that buckling piece 10 is upwards improper mobile with respect to radiator 20 at its lengthwise.The central authorities of this pressure section 122 and second extension 136 offer a punching 140 respectively, the medial margin of this two punching 140 tiltedly stretches out a card 142 respectively, fixes respectively on radiator 20 pedestals 22124 and to dash the fin 144 that is provided with the structural strength that is used for strengthening clinching body 12 in addition.

Each buckling body 16 has a recessed slightly press section 162, further extend a snap-latch piece 164 downward vertically behind downward reflexed one segment distance of one end of this press section 162, this snap-latch piece 164 forms a draw-in groove 166 that supplies this holding section 126 to wear in the position of corresponding clinching body 12 holding sections 126.This snap-latch piece 164 extends a cramp 168 downwards, offer on the cramp 168 with stuck-module 40 end walls 44 on the button hole 170 of projection 48 buckles.

Please together consult Fig. 1 to Fig. 5, pass the draw-in groove 166 (the barb-like structure that the groove 128 on this clinching body 12 can provide holding section 126 ends is the space of strain inwardly) of buckling body 16 by the holding section 126 of clinching body 12, and block the draw-in groove 166 of buckling body 16 with the location notch 130 of clinching body 12, just clinching body 12 and buckling body 16 can be combined.

When radiator 20 fits to central processing unit 30 end faces and its both ends and is contained in this two stuck-module 40 respectively, buckling device of radiator 1 is attached on the radiator 20, and the catch 138 on the buckling piece 10 clinching bodies 12 is contained in the vertical trench 28 of radiator 20, the card 142 on the buckling piece 10 clinching bodies 12 fixes respectively in the elongated slot 26 of radiator 20 pedestals 22 upper and lower surfaces at this moment.For making whole fastening process smooth-going, then can push the press section 162 of two buckling pieces, 10 clinodiagonal engaging bodies 16 earlier, make button hole 170 on each buckling body 16 cramp 168 withhold projection 48 on these two stuck-modules, 40 diagonally opposing corners respectively, afterwards, another organizes the press section 162 of clinodiagonal buckling body 16 to push two buckling pieces 10, make the button hole 170 on each buckling body 16 cramp 168 withhold the projection 48 on another group diagonally opposing corner on this two stuck-module 40 respectively, promptly finish assembling.
