Description

Fastener of heat sink

[technical field]

The utility model is about a kind of fastener of heat sink, refers in particular to a kind ofly to install and remove convenient and the button solid fastener of heat sink that keeps steady.

[background technology]

Along with integrated circuit to the high density integrated development, the heat of its generation is more and more many, temperature is also more and more higher, and that temperature is too high when integrated circuit is moved is stable totally unfavorable.For this reason, industry is installing one radiator on integrated circuit usually, and by a fastener this radiator closely is sticked in integrated circuit surface, assists heat is discharged.

Traditional heat-dissipating device fastener is of a great variety, as No. the 86209116th, Taiwan patent application, disclose a kind of fastener that adopts single medal spring bar bending forming, this fastener is crossed on the radiator top, and its two ends are buckled in respectively in the clinodiagonal circuit board through-hole of this radiator, thereby make this radiator be installed in integrated circuit surface.But this class fastener is to be formed by the bending of single medal spring bar, and only adopts 2 modes that are fastened in diagonal angle, so that button is held power is very limited, and radiator firmly can't be sticked in integrated circuit surface; Secondly, when this class fastener is installed and removed usually, utilize finger directly to push its elastic arm and operate, so very easily make finger impaired because of careless manipulation.

[summary of the invention]

The purpose of this utility model is to provide a kind of and installs and removes convenient and the button solid fastener of heat sink that keeps steady.

The purpose of this utility model is achieved through the following technical solutions: the utility model fastener of heat sink is mainly used to a radiator closely is sticked in an integrated circuit surface, and this fastener of heat sink mainly comprises one first fastener and one second fastener.These first fastener central authorities are a pressure section, and an elastic portion is outwards tiltedly stretched out at these pressure section two ends respectively, and sheathed one push handle on the elastic portion therein, and the free end of these elastic portion is bent to form a grab respectively in addition.This second fastener comprises a horizontal fixed portion that roughly is zigzag, the central pressure section with this first fastener of this horizontal fixed portion intersects stacked, and these fixed part two free ends outwards tiltedly stretch out a kink respectively, wherein also sheathed one push handle on the kink, the end of these kinks is bent to form a card respectively and angles in addition.

Compared with prior art, the utility model fastener of heat sink closely is sticked in integrated circuit surface radiator by the two-piece type fastener; Therefore simultaneously, the sheathed handle of pushing on elastic portion has that mounting or dismounting are convenient, button keeps steady solid advantage.

With reference to the accompanying drawings, in conjunction with the embodiments the utility model is further described.

[embodiment]

See also Fig. 1, the utility model fastener of heat sink is mainly used to a radiator 60 closely is sticked on integrated circuit 80 surfaces of a circuit board 70 (detailed aftermentioned).Wherein, this radiator 60 comprises a pedestal 64 and some radiating fins 62 that extends upward and be in array-like arrangement from these pedestal 64 surfaces, and the prominent respectively fin 66 that sets out in the relative outside of the adjacent two row's radiating fins 62 of central authorities, be used for cooperating with a fixed block 30, thus this fastener of heat sink is pre-aligned on radiator 60; And this circuit board 70 offers a rectangle button hole 76 respectively around this integrated circuit 80, is used for being clasped with fastener of heat sink.

Please together consult Fig. 2 and Fig. 3, this fastener of heat sink comprises one first fastener 40 and one second fastener 50, and this first fastener 40 can intersect stacked with second fastener 50 and press card to be positioned at radiator 60 pedestals 64 end faces by fixed block 30.Wherein, this first fastener 40 is formed by medal spring bar bending, and central authorities are a pressure section 42; This relative reversed dip in pressure section 42 two ends extends an elastic portion 44, and therein on the elastic portion 44 sheathed plastics push handle 10, the application of force when being convenient to operate; The free end of these elastic portion 44 is bent to form a grab 46 respectively in addition, is clasped with the corresponding button hole 76 of circuit board 70.This second fastener 50 comprises a horizontally disposed fixed part 52 also by a medal spring bar bending forming; This fixed part 52 roughly is zigzag, and its central authorities are stacked with pressure section 42 of this

first fastener

40, and 52 liang of free ends of this fixed part extend a kink 54 respectively obliquely, and wherein also sheathed plastics are pushed handle 10 on the kink 54, are convenient to pressing operation; The end of these kinks 54 is bent to form a grab 56 respectively in addition, is clasped with the corresponding button hole 76 of circuit board 70.

Please continue to consult Fig. 4, during assembling, assembly with this fastener of heat sink and radiator 60 is placed on this integrated circuit 80 surfaces earlier, and make four grabs 46 of this fastener of heat sink, 56 the button hole 76 with circuit board 70 is corresponding one by one respectively, then it is not established the elastic portion 44 of pushing handle 10 and the grab 46 of kink 54 ends, 56 are fastened in the corresponding button hole 76, push the sheathed handle 10 of pushing on this fastener of heat sink first fastener 40 and second fastener 50 at last respectively, make the grab 46 of its corresponding end, 56 are fastened in the corresponding button hole 76 of circuit board 70, this radiator 60 firmly is sticked on integrated circuit 80 surfaces, promptly finishes assembling.
