Description

Buckling device of radiator

The utility model relates to a kind of buckling device of heating radiator, refers in particular to that a kind of dismounting is easy, the button solid buckling device of radiator that keeps steady.

Along with central processing unit (CPU) towards at a high speed and the high performance development, the heat of its corresponding generation is also more and more many, if untimely discharge heat, to the central processing unit reliability of operation with totally unfavorable.For this reason, industry often has heating radiator in the central processing unit mounted on surface, with the relevant heat of timely discharge.Keep between central processing unit and the heating radiator closely contact to reach preferable thermal conduction effect for making, often need extra installation fastener to assist.Existing fastener kind is a lot, and fastener just is one of them as shown in Figures 1 and 2.This fastener 1 be provided with that level is horizontally set with by branch 2, should be inclined upwardly by branch's 2 two ends one and extend shell fragment 3, shell fragment 3 ends extend side plate 4 downwards.All offer low opening 5 and higher opening 6 on each side plate 4, wherein low opening 5 in order to the counter structure buckle (please refer to Fig. 2) of connector 8, and the base of higher opening 6 also be extended with obliquely outwardly for when dismounting as the sheet metal 7 of the instrument point of applications such as finger or bottle opener.

Above-mentioned existing fastener comes the mode of dismounting with finger or instrument such as bottle opener, because of being subjected to the restriction of the limited activity space of computer-internal, so very inconvenient in the operation.Moreover, very easily cause injury to personnel and efficient not good with finger manipulation, and utilized child-operation very easily and skidding takes place between the sheet metal of fastener, even the scratch motherboard.

The purpose of this utility model is to provide that a kind of dismounting is easy, the button solid buckling device of radiator that keeps steady.

Therefore, the purpose of this utility model is achieved through the following technical solutions: this buckling device of radiator comprises plastic cement handle and metal fastener, wherein this handle has the press section, this press section is extended with clamping part downwards, and this fastener is provided with pressure section, have the fin or the bead structure that can strengthen fastener structures intensity on this pressure section, and after extending earlier obliquely, an end of this pressure section is bent to form first cramp downwards, the other end then extends and bends out second cramp relative with this first cramp, the both side edges of this second cramp respectively to evagination establish a pair of in order to inlay card in the handle slot and the latch that handle and fastener are combined.

Compared with prior art, the utlity model has following remarkable advantage: this buckling device of radiator is operated by the press section of pushing handle, so dismounting is quite easy.Moreover crimping or rib structures on this fastener pressure section can strengthen the structural strength of fastener and provide bigger button to hold power, so that button is held is quite firm.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 6 is another embodiment three-dimensional exploded view of the utility model buckling device of radiator.

See also Fig. 3, the utility model buckling device of radiator 20 comprises plastic handle 22 and metal fastener 24.This handle 22 is provided with

press section

26, and 26 bottoms, press section are extended a clamping part 28 downwards and made handle 22 roughly be the T font.Extend tabs 32 inwardly after the both side edges of this clamping part 28 is extended in opposite directions, be formed with slot 34 (describing in detail as the back) between the inside surface of this tabs 32 and clamping part 28 for metal fastener 24 inlay cards.

This fastener 24 has pressure section 36, one end of pressure section 36 is bent to form first cramp 38 downwards after extending obliquely earlier, the other end then extends obliquely earlier and is bent to form up all to be provided with near the end that forms second cramp, 44, the first cramps 38 and second cramp 44 behind the bend 42 downwards and is used for and the projection 82 of connector 80 button hole 46 of buckle (please refer to Fig. 4 or Fig. 5) mutually.The both side edges of this pressure section 36 bends respectively extends in order to strengthen crimping 48 structures of fastener 24 structural strengths, in order to strengthen the structural strength of fastener 24.In the appropriate position of second cramp, 44 both side edges, dash forward to external symmetry respectively and establish a pair of latch 54, but in the slot 34 of inlay card handle 22, thereby handle 22 and fastener 24 are combined.

Please consult Fig. 4 and Fig. 5 simultaneously, during assembling, utilize the inlay card of 34 of latch 54 and slots to cooperate earlier and handle 22 and fastener 24 are combined, this moment, the press section 26 of this handle 22 was resisted against on the bend 42 of fastener 24.When central processing unit 70 is installed on the connector 80 and heating radiator 60 when placing on the central processing unit 70, the pressure section 36 of fastener 24 is put in the central groove 62 of heating radiator 60.Then, the button hole 46 on fastener 24 first cramps 38 is fastened connector 80 projection 82 on one side.At last, push the press section 26 of handle 22, the projection 82 that makes button hole 46 on second cramp 44 fasten connector 80 another sides is just finished assembling, and heating radiator 60 and central processing unit 70 are fitted tightly together.

During dismounting, push the press section 26 of handle 22, but make the button hole 46 on fastener 24 second cramps 44 on the projection 82 of connector 80, break away from just complete operation.

See also Fig. 6, this is another embodiment of the utility model buckling device of radiator, and it comprises plastic handle 22 ' and metal fastener 24 '.Pressure section 36 ' the upper punch of this fastener 24 ' is provided with the fin 52 that strengthens fastener 24 ' structural strength.
