Description

Fastener of heat sink

The utility model is about a kind of fastener of heat sink, is meant the easy and labour-saving fastener of heat sink of a kind of loading and unloading especially.

Along with the development of central processing unit (CPU) towards the direction of high-frequency high-speed and small size, the heat that it produced is increasing, and temperature is also more and more higher.Can normal operation in order to ensure central processing unit, in time discharge heat, installing one has the heating radiator of great heat radiation effect on central processing unit usually.In order to reach preferable thermal conduction effect, industry often adopts a kind of fastener to guarantee to fit tightly together between central processing unit and the heating radiator.

Existing fastener kind is a lot, is one of them as shown in Figure 1.This fastener 1 has a pressure section 2, and this pressure section can be put into the formed groove of radiating fin (figure does not indicate) of heating radiator, is used for compressing this heating radiator.A buckle arm 3 is extended at the two ends of this pressure section 2 bending downwards respectively, respectively offer a block button hole 4 near the free end of each buckle arm 3, in order to the connector sidewall on projection (figure indicate) buckle mutually, thereby by pressure section 2 heating radiator is fitted tightly on central processing unit.In addition, this buckle arm 3 is also offered a sled hole 5 above block button hole 4, so that utilize for aid (figure does not indicate) when assembling or dismounting.Because this fastener 1 when assembling or dismantle, needs insert by aid in addition also outwards to pull fastener 1 ability complete operation in the sled hole 5, so extremely inconvenient.

The purpose of this utility model is to provide a kind of loading and unloading convenient and labour-saving fastener of heat sink.

The purpose of this utility model is achieved through the following technical solutions: the utility model fastener of heat sink comprises a button and a resilient handle, this button mainly comprises a pressure section, one end of this pressure section roughly is bent to form one first cramp after one first elastic arm is extended in bending obliquely earlier more downward vertically, the other end of this pressure section also bending obliquely extends one second elastic arm, and the end of this second elastic arm roughly is bent to form second cramp relative with this first cramp downward vertically.Be respectively equipped with one first button hole and one second button hole near the end of this first cramp and second cramp, be provided with upwardly extending first tongue piece on the approximately central position of this second elastic arm, the top of this first tongue piece extends to form one first clasp towards the bending of pressure section direction.This second cramp also is provided with second tongue piece that extends outside one day above second button hole, the end of this second tongue piece is bent to form one second clasp downwards.This resilient handle comprises one first brace, one second brace and a handle part, be provided with one near the free end of this first brace and be used for and first clasp of button, first connecting hole of buckle mutually, also be provided with one near the end of this second brace and be used for and second clasp of button, second connecting hole of buckle mutually.

By technique scheme, make the utility model fastener of heat sink convenient disassembly and succinctly laborsaving, while can avoid the drawback of operating by aid.

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

Fig. 1 is the stereographic map of existing fastener of heat sink.

Fig. 2 is the three-dimensional exploded view of the utility model fastener of heat sink and associated component.

Fig. 3 is the three-dimensional combination figure of Fig. 2.

Please together with reference to readding Fig. 2, Fig. 3, the effect of the utility model fastener of heat sink 50 is that heating radiator 60 is fitted tightly on the end face of central processing unit 70.Wherein, this central processing unit 70 is plugged on the connector 80, and stretching out respectively in the two lateral walls of this connector 80 is provided with one and can supplies the projection 82 of fastener of heat sink 50 buckles (describing in detail as the back).This heating radiator 60 comprises that a pedestal 62 and several are located at the radiating fin 64 on the pedestal 62, and is used to accommodate the groove 66 of fastener of heat sink 50 in central authorities' formation one of heating radiator 60.

This fastener of heat sink 50 comprises that a button 20 and is combined in the resilient handle 40 on the button 20.Button 20 is bent to form by long-bar metal sheet integrated punching, mainly comprises a pressure section 29, and this pressure section 29 just can be placed in the groove 66 of heating radiator 60, is used for compressing this heating radiator 60.One end of this pressure section 29 roughly is bent to form one first cramp 22 after one first elastic arm 21 is extended in bending obliquely earlier more downward vertically, and the end of this first cramp 22 is provided with one and is used for and the projection 82 of connector 80 1 sides first button hole 23 of buckle mutually.The other end of this pressure section 29 also bending obliquely extends one second elastic arm 24, the end of this second elastic arm 24 roughly is bent to form second cramp 27 relative with this first cramp 22 downward vertically, is provided with one at the end of this second cramp 27 and is used for and the projection 82 of connector 80 opposite sides second button hole 28 of buckle mutually.This second elastic arm 24 is provided with upwardly extending first tongue piece 25 on approximately central position, the top of this first tongue piece 25 extends to form one first clasp 26 towards the bending of pressure section 29 directions.This second cramp 27 also is provided with second tongue piece 31 that extends outside one day above second button hole 28, the end of this second tongue piece 31 is bent to form one second clasp 32 downwards.

This resilient handle 40 also is bent to form by long-bar metal sheet integrated punching, comprise one first brace 41, one second brace 42 and a handle part 43, be provided with one first connecting hole 44 near the free end of this first brace 41, be used for and first clasp 26 of button 20 buckle mutually.43 of this handle parts are to be stretched out by first brace 41 that turnover bends out one section circular arc that is positioned at first brace, 41 belows down behind the segment distance, and then extend obliquely until almost contacting this first brace 41 and form, the operation force application part when this handle part can be as installing/dismounting.This second brace 42 is to be extended to form by the slightly downward-sloping bending of the end of this handle part 43, also is provided with one near its end and is used for and second clasp 32 of button 20, second connecting hole 45 of buckle mutually.

When making up this fastener of heat sink 50, first clasp 26 is distinguished buckle mutually with first connecting hole 44, second clasp 32 and second connecting hole 45, this moment, this resilient handle 40 was incited somebody to action flexibly opened with certain angle, fastener effect by first clasp 26 and second clasp 32 and resilient handle 40 elastic restoring force when assembled state, this resilient handle 40 will be combined on the button 20 and difficult drop-off securely.

Please refer to Fig. 3, during assembling, earlier central processing unit 70 is plugged on the connector 80, and heating radiator 60 is placed on the end face of central processing unit 70.Then, the handle part 43 of the resilient handle 40 of the hand-holdable fastener of heat sink 50 of operator tiltedly is placed into fastener of heat sink 50 in the groove 66 of heating radiator 60, and the projection 82 that makes first button hole 23 and connector 80 buckle mutually.Then, the operator pushes the handle part 43 of resilient handle 40 downwards, and another projection 82 of second button hole 28 and connector 80 on second cramp 27 is fastened mutually, promptly finishes assembling.
