AI Technical Summary

Problems solved by technology

If the fins of the heat sink are thin, the extrusion force will easily cause the fins to deform, causing the ring of the fastening element to fall off the fins, so that the fastening element cannot fix the heat sink
As a result, the contact between the heat sink and electronic components will be extremely unstable and will be greatly affected by the shape of the fins

Embodiment Construction

[0016] Such as figure 1 As shown, the fastening device assembly 20 of the present invention is used to fix a heat sink 10 to an electronic component 30 . The electronic components 30 are installed in the middle of a circuit board 40 . The circuit board 40 is provided with two screw holes 44 near the position of the electronic component 30 for passing through the corresponding structure of the fastening device assembly 20 . A bracket 42 extends upward from the right side of the circuit board 40 . The bracket 42 includes two supporting rods (not marked) respectively formed at two adjacent corners of the circuit board 40 and a cross bar (not marked) connecting the two supporting rods, wherein each supporting rod is perpendicular to the circuit board 40. The cross-bar is parallel to the circuit board 40 and has a circular cross-section for matching with the corresponding structure of the fastening device assembly 20 .

Abstract

The invention provides a lock device assemble, which is used for fixing a radiator to an electronic component installed on a circuit board, the circuit board forms a supporting rack upward. The lock device assemble includes a base for a radiator to combine with and two lock components located on the double sides of the radiator separately. Every lock component includes an arm part and a supporting part which extends downward from one side of the arm part. The arm part presses the base. The supporting part is against the circuit board to support the arm part, and the other end of the arm part locks with the supporting rack for ensuring the arm part to press the base downward.

Description

technical field [0001] The invention relates to a fastening device combination, in particular to a fastening device combination for fixing a heat dissipation device to an electronic device. Background technique [0002] High-power electronic components such as computer central processing unit, north bridge chip, and graphics card will generate a lot of heat during operation. If the heat cannot be effectively dissipated, it will directly lead to a sharp rise in temperature, which will seriously affect the performance of electronic components. normal operation. For this reason, a heat sink is required to dissipate heat from these electronic components and a fastening device for fixing the heat sink to the electronic components. [0003] Chinese Patent No. 01215323.0 discloses a combination of cooling devices. The heat dissipation device combination includes a heat sink and a fastening element for fixing the heat sink to the electronic components. The radiator includes a bas...
