Embodiment Construction

[0015] see Figure 1 to Figure 2 , the radiator fastening device 10 in one embodiment of the present invention is used to fix the radiator 40 on the circuit board 30, the radiator fastening device 10 straddles the radiator 40 and is located on the back of the circuit board 30. Plate 20 fits.

[0016] The circuit board 30 is mounted with a heating electronic component 32 , and has circular installation holes 34 respectively located outside two ends of the electronic component 32 .

[0017] The heat sink 40 is made of metal materials with good thermal conductivity such as aluminum, copper, etc., and it includes a base plate 41 that is in contact with the top surface of the electronic component to absorb the heat generated by the operation of the electronic component and a number of heat sinks that are arranged in parallel on the base plate 41. Cooling fins 43, a long slot 45 is provided in the middle of these cooling fins 43 to accommodate the radiator fastening device 10, and ...

Abstract

The present invention discloses a radiator snap-fit device, which comprises a resist pressing component. One end of the resist pressing component extends outward horizontally and is provided with a joint part. The present invention also comprises a continue component which is placed above the joint part, a connection component which is rotationally connected with the continue component, a bolt and a screw component. A chute is arranged in the middle of the connection component. The bolt is slipping arranged in the chute and fixed on the joint part. The screw component comprises a first screw and a second screw. A male screw which is respectively rotated and matched with the continue component and the joint part and is in the opposite screw direction is arranged on the first screw and the second screw. The opposite screw structure of the screw component is capable of adjusting the screw degree between the screw component and the continue component and the resist pressing component. So the distance between the continue component and the resist pressing component is controlled to select the volume of snap-fit force and to be suitable for different requirements.

Description

technical field [0001] The invention relates to a fastening device, in particular to a fastening device for fixing a heat sink for cooling electronic components on a circuit board. Background technique [0002] General electronic components, such as the central processing unit, generate a lot of heat during operation, which increases the temperature of itself and the system. Excessively high temperatures will degrade its operating performance. For this reason, the industry usually installs heat sinks on electronic components to dissipate the large amount of heat generated by them. In order to ensure that the heat sink and the electronic components can be in close contact and heat transfer is sufficient, it is usually necessary to use a fastening device to assist the fastening of the heat sink. [0003] Such as Figure 6 As shown, a radiator radiator fastening device is disclosed, which has: a buckle rod 51, and a buckle arm 511 is bent and extended at both ends thereof, so ...
