Abstract
The present invention relates to a fastener of a radiator, which is integrally punched and folded by metal sheets. The present invention approximately comprises a pressing section and a perpendicular section which are mutually perpendicular and extensive; the pressing section is used as independence for the force application of the fastener; the upper part of the perpendicular section is inwardly and downwards extended with an elastic piece in the shape of an arc, the elastic piece is used as the source of butting elastic force of the fastener, and the free end of the perpendicular section is provided with a pair of clamping hooks which are used for buckling installing holes of a circuit board; gaps are formed above the clamping hooks, and the height of the gap is roughly equal to the thickness of the circuit board; a longitudinal notch which is formed between the clamping hooks can be used as space required for inward elastic deformation of the clamping hooks.
Description
The invention relates to a kind of fastener of heat sink, be meant that especially a kind of structure simplifies, assembles easy fastener of heat sink.
Existing fastener of heat sink and associated component structure please refer to Fig. 1, and its chips 54 is to be welded on the circuit board 50, and this circuit board 50 offers in the outside, two diagonal angles of chip 54 and uses the installing hole 51 that wears buckle for fastener 56.Radiator 52 roughly is cuboid, and its two diagonal angle lug that extends outwardly out respectively is formed with through hole 53 on this lug.During assembling, earlier radiator 52 is placed on chip 54 end faces, make the installing hole 51 on the through hole 53 alignment circuit plates 50 of radiator 52 simultaneously, afterwards, with fastener 56 cover upper springs 55 and pass through hole 53 and installing hole 51 in regular turn, the elastic force by spring 55 fits tightly radiator 52 and chip 54 end faces.Above-mentioned existing structure is after being sheathed on spring 55 on the fastener 56 earlier, fastener 56 is passed in regular turn the through hole 53 of radiator 52 and the installing hole 51 of circuit board 50 again, and not only number of spare parts is more, and cost is higher, and assembly program is also more loaded down with trivial details.
The object of the present invention is to provide a kind of structure to simplify, assemble easy fastener of heat sink.
The objective of the invention is to be achieved through the following technical solutions: fastener of heat sink of the present invention is to be formed by the bending of sheet metal integrated punching, roughly comprises the press section and the vertical component effect that are perpendicular to one another and extend, and this press section is relying on as the fastener application of force.A shell fragment that compresses the elastic force source that is used as fastener is extended on the top of this vertical component effect inwardly and downwards arcuation, and free end then forms a pair of grab and comes installing hole on the buckle circuit board.The top of this grab also is formed with breach, the rough thickness that equals circuit board of the height of this breach.Between this is to grab, be formed with a vertical notch, can be used as the grab needed space of strain inwardly.
Compared with prior art, the present invention has following distinguishing feature: fastener of heat sink of the present invention does not need to be undertaken by other instrument is auxiliary when operation, and all quite easy during mounting or dismounting, structure is simplified, and button is held also quite firm.
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is the three-dimensional exploded view of fastener of heat sink of the present invention and associated component.
Fig. 2 is the three-dimensional combination figure of Fig. 1.
Fig. 3 is the stereogram of another embodiment of fastener of heat sink of the present invention.
Fig. 4 is the stereogram of the another embodiment of fastener of heat sink of the present invention.
Fig. 5 is the three-dimensional exploded view of existing fastener of heat sink and associated component.
Please, be the three-dimensional exploded view and the constitutional diagram of fastener of heat sink of the present invention and associated component together with reference to figure 1 and Fig. 2.Its chips 5 is to be welded on the circuit board 1, and this circuit board 1 offers in the outside, two diagonal angles of chip 5 and uses the installing hole 6 that wears buckle for fastener 10.This radiator 2 roughly is square, and its two diagonal angle lug 7 that extends outwardly out respectively is formed with on this each lug 7 and uses the rectangular through holes 8 that wears for fastener 10.
(please refer to Fig. 2) when assembling is finished, the grab 14 of fastener 10 can withhold circuit board 1 bottom surface, and the lug 7 that the shell fragment 12 of fastener 10 is then replaced radiator 2 is used as compressing the elastic force source.
Because fastener 10 of the present invention is to be formed by sheet metal integrated punching bending, so structure simplifies, and assembling easily.
See also Fig. 3, be another embodiment of fastener of heat sink of the present invention.Wherein the press section 25 of fastener 20 outwardly and downwards arcuation extend, except relying on, also can be used as the source that compresses elastic force simultaneously as the application of force.
See also Fig. 4, be the another embodiment of fastener of heat sink of the present invention.Wherein the press section 35 of this fastener 30 can rely on as the application of force simultaneously and compress the elastic force source, then is formed with one on the vertical component effect 37 and the tongue piece 32 that extends obliquely inwardly.When assembling was finished, tongue piece 32 propped up lug 7 bottom surfaces of radiator 2, and the strength that prevents press section 35 strains is excessive and cause fastener 30 and circuit board 1 to break away from.
Claims (5)
1. fastener of heat sink, be to form by the bending of sheet metal integrated punching, comprise press section and vertical component effect, it is characterized in that: the press section is to rely on as the application of force, extend vertically downward and form and vertical component effect is a end by the press section, extend one on this vertical component effect inwardly as the elastic construction that compresses elastic force source, its free end is formed with a pair of grab, is formed with one as grab vertical notch of strain requisite space inwardly between this is to grab.
2. fastener of heat sink as claimed in claim 1 is characterized in that: this elastic construction is one by the top of the vertical component effect shell fragment that extends of arcuation downwards inwardly.
3. fastener of heat sink as claimed in claim 1 is characterized in that: this press section is arcuation extension downwards outwardly, except relying on as the application of force, also as the source that compresses elastic force.
4. fastener of heat sink as claimed in claim 1 is characterized in that: this press section is to rely on and the source that compresses elastic force as the application of force simultaneously, and this elastic construction is a tongue piece that extends obliquely inwardly.
5. fastener of heat sink as claimed in claim 1 is characterized in that: the top of this grab also is formed with breach.
