Abstract

The utility model relates to a fastener for a radiating device. The utility model is provided with a pressing elastic piece; the pressing elastic piece is provided with a butting section and an extension arm which are respectively, symmetrically and upwards extended from the both ends of the butting section inclination; the end of each extension arm is extended with an L-shaped fastening arm, a negative of each fastening arm is provided with two fastening holes which are ranged in apposition, and the bottom sides of the fastening holes which are arranged on the outer end are arc-shaped.

Description

Fastener of heat radiator

The utility model relates to a kind of fastener of heat radiator, is meant the fastener of heat radiator that a kind of central processing unit is used especially.

Along with developing rapidly of computer industry, the arithmetic speed of central processing unit is more and more faster, and the ability of computer deal with data also strengthens greatly.But what follow appearance is that the heat that central processing unit produces sharply increases, can't normal operation for fear of the too high central processing unit that causes of temperature, therefore must on central processing unit, add a heat abstractor.In addition, closely contact with central processing unit,, install a fastener usually additional between the two to reach better heat radiating effect in order to make heat abstractor.The fastener of prior art can be with reference to United States Patent (USP) the 5th, 602, No. 719, this fastener has an elastic part, place in the formed groove of radiating fin of heat abstractor, an oblique arm is extended at two ends at elastic part respectively obliquely, and this two oblique arm further extends first end and the second end.First end is provided with first button hole, in order to the projection buckle of connector on one side; The second end has an operating portion and an arm, and arm is provided with second button hole, in order to the connector another side on the projection buckle.When being fixed in heat abstractor on the wafer with fastener, first button hole of fastener and second button hole will be respectively and the projection buckle of connector, and the elastic part of fastener then compresses heat abstractor, and the wafer on making heat abstractor and being plugged in connector closely contacts.But, because the first end and the second end of fastener all only have a button hole, buckle between itself and connector projection and built on the sand, thereby when utilizing this fastener to fit in heat abstractor on the wafer, very easily the button hole that causes fastener because of vibrations comes off from the projection of connector, and can't effectively heat abstractor be fitted on the wafer.

The fastener of heat radiator that provides a kind of central processing unit to use is provided the purpose of this utility model, and this fastener of heat radiator can firmly fit in heat abstractor on the central processing unit, and production cost reduces significantly and production efficiency improves greatly.

The technical solution of the utility model is: this fastener of heat radiator has a pressure section, the two ends of pressure section tilt to extend upward an adjutage respectively, the end of each adjutage extends a ＂ L ＂ shape snapping arm downwards, be set side by side with two button holes on the egative film of each snapping arm, and this base of button hole that is positioned at the outer end is curved.

Owing to adopted such scheme, the utility model can firmly fit in heat abstractor on the central processing unit effectively and production cost reduces significantly and production efficiency improves greatly.

Fig. 1 is the isometric exploded view of the utility model fastener of heat radiator and heat abstractor, central processing unit and connector.

Fig. 2 is the three-dimensional assembled view of Fig. 1.

In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.

In Fig. 1, fastener of heat radiator 10 has a pressure section 22, and pressure section 22 places in the radiating fin 62 formed grooves 64 of heat abstractor 60, and the upper surface 66 of heat abstractor 60 is replaced in its bottom surface.The two ends of pressure section 22 symmetry that tilts respectively extends upward an adjutage 24, the end of each adjutage 24 extends a ＂ L ＂ shape snapping arm 28 downwards, be set side by side with two

button holes

30,32 on the egative film of each snapping arm 28, respectively with connector 100 relative edges on projection 102 and snapping piece 104 buckles, so that heat abstractor 60 is fitted tightly on central processing unit 80.This base of button hole 32 that is positioned at the outer end is curved, with corresponding with the cambered surface 106 of snapping piece 104 bottoms, and

button hole

32 and 104 of snapping pieces can be closely cooperated and snapping firm.

The projection 102 of this connector 100 roughly is positioned on the center line of connector 100, snapping piece 104 then symmetry is positioned at connector 100 center line both sides, therefore the egative film of this two snappings arm 28 is each other and oppositely extends, in order to the projection 102 and snapping piece 104 respective outer side edges of connector 100.

Please refer to Fig. 2, is the three-dimensional assembled view of fastener of heat radiator 10 and heat abstractor 60, central processing unit 80 and connector 100.Wherein a snapping arm 28 of this fastener of heat radiator 10 earlier with projection 102 and snapping piece 104 buckles of connector 100 on one side, by pushing and the egative film of another snapping arm 28 being moved on the projection 102 and snapping piece 104 that is snapped in connector 100 other limits, promptly finish the snapping process downwards inwardly.If desire removes this fastener of heat radiator 10, then by pushing downwards and the egative film of a snapping arm 28 is moved outwardly and breaking away from from the projection 102 of connector 100 and snapping piece 104 and to get final product.

Owing to be formed with two

button holes

30,32 respectively on the egative film of each snapping arm 28 of fastener of heat radiator 10, and the base of button hole 32 that is positioned at the outer end is curved, therefore can closely cooperate with the dependency structure of connector 100, and heat abstractor 60 is firmly fitted on the central processing unit 80.

Because this fastener of heat radiator 10 is integrate shaped types, thus only need a mold to make, and product do not need to assemble separately, therefore can reduce production costs significantly and enhance productivity.

Claims
