Abstract

The utility model discloses a heat radiator buckle assembly with two grabs. The buckle assembly is prepared by bending a metal elastic body, and comprises a middle portion, wherein two supporting portions are oppositely extended outwardly from both ends of the middle portion, a bending portion is freely and outwardly extended from the end of the support portion, and two grabs are respectively formed by bending at both ends of the bending portion. Convex ribs are particularly arranged on the heat dissipation fins corresponding to the support portion on the pedestal of the heat radiator. When assembling, the buckle assembly is fixed on the heat radiator by the actions of the convex ribs and support portions. Two buckle holes are particularly arranged on the heating element. The heat radiator buckle assembly having two grabs makes the heat radiator to stably adhere on the corresponding heating element by the actions of the grabs on the buckle assembly and the buckle holes on the heating element. Comparing to the prior art, the utility model has the advantages of simple structure, convenient assembly, in favor of automatic assembly, improved productive capacity, no damage to the product when assembling, and low cost.

Description

Two grab fastener of heat sink

Technical field

The utility model relates to a kind of two grab fastener of heat sink, particularly relates to a kind of ease of assembly, the difficult two grab fastener of heat sink that scratch product.

Background technology

Traditional heat-dissipating device and fastener are of a great variety, arrive shown in Figure 3 as Fig. 1, a kind of fastener of heat sink, this fastener of heat sink comprises that one roughly is Z font fastener 10, there is a press part 11 in these fastener central authorities, and the outside bending member 12 that freely extends in these press part 11 two ends, the end of these bending members 12 is bent into a grab 121 respectively; On radiator base 14, with press part 11 corresponding positions, ad hoc have a shell fragment 13, during assembling, utilizes the effect of shell fragment 13 and press part 11 that fastener 10 is fixed on the radiator base 14.

Above-mentioned fastener of heat sink is ad hoc button hole effect on grab 121 and the heater that utilizes on the fastener 10, and makes heating radiator be positioned on the corresponding heater.

The shortcoming of this fastener of heat sink is: in the assembling process, shell fragment 13 is in the process that presses down, and is easy to boss with radiator base 14 and weighs wounded with scratch and expose base material, causes bad order; Shell fragment is difficult for placed in the middle in assembling process, and it is placed in the middle to cause fastener to be difficult for, and product is done over again.

Summary of the invention

For addressing the above problem, the utility model proposes a kind of fastener of heat sink, this fastener of heat sink is the fastener that heating radiator is fixed, it comprises a pars intermedia, two pressure sections are extended at the portion two ends in opposite directions hereinto, this pressure section is terminal outwards freely to stretch out a kink, and the end of these kinks is bent into a grab respectively; On radiator base, on the corresponding radiating fin of pressure section, ad hoc have a fin.

During assembling, utilize the effect of fin and pressure section that fastener is fixed on the radiator base.

Ad hoc on heater have two button holes, and above-mentioned two grab fastener of heat sink are to utilize ad hoc button hole effect on grab on the fastener and the heater, and make heating radiator firmly be sticked on the heater of correspondence.

Advantage of the present utility model is: compared to the prior art, structure is simpler, and is easy to assembly, helps the automat assembling, improves production capacity; Be difficult for scratching product during assembling, save cost.

Embodiment

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.

Arrive shown in Figure 6 as Fig. 4, a kind of fastener of heat sink, be mainly used to heating radiator closely is sticked on the heater surface, wherein, this heating radiator comprises a pedestal 24 and some radiating fins 25 that extends upward and be the arrangement of array shape from this base-plates surface, and on the radiating fin 25 corresponding, prominently respectively set out fin 251, thereby this fastener of heat sink 20 is positioned at (as Fig. 5) on the radiator base 24 with fastener 20 pressure sections 21; And this heater and fastener 20 grabs 221 corresponding angles offer a button hole respectively, are used for cooperating with fastener of heat sink grab 221.

As shown in Figure 4, a kind of fastener of heat sink, this fastener 20 is formed by metallic elastic bar bending, it comprises a pars intermedia 23, two pressure sections 21 are vertically extended at portion 23 two ends in opposite directions hereinto, these pressure section 21 ends outwards freely stretch out a kink 22, and the end of these kinks 22 is bent into a grab 221 respectively; On radiator base 24, on pressure section 21 corresponding radiating fins 25, ad hoc have a fin 251.

This fastener 20 is to be placed in the space of radiating fin 251, during combination, two pressure sections 21 is pressed in the fin 251, utilizes the effect of fin 251 and pressure section 21 that fastener 20 is fixed on the radiator base 24; Because of folding between two pressure sections 21 has a pars intermedia 23, make pressure section 21 locate easily, and the fixing of fastener 20 also become simple and direct.

Ad hoc on heater have two button holes, the heating radiator fixed form is, assembly with this fastener of heat sink 20 and heating radiator is placed on the heater surface earlier, and the button hole with heater is corresponding one by one respectively to make two grabs 221 of this fastener of heat sink 20, then grab 221 is pressed in the corresponding button hole, utilize ad hoc button hole effect on grab 221 and the heater on the fastener 20, and make heating radiator firmly be sticked on the heater surface of correspondence.

Claims

1. grab fastener of heat sink, this fastener of heat sink is the fastener that heating radiator is fixed, it is characterized in that: this fastener comprises a pars intermedia, two pressure sections are extended at the portion two ends in opposite directions hereinto, the terminal kink that outwards freely stretches out of this pressure section, the end of these kinks is bent into a grab respectively, is being provided with fin on the radiator base with on the corresponding radiating fin of fastener pressure section in addition.

2. two grab fastener of heat sink according to claim 1 is characterized in that: its pressure section and kink all are elastic device.
