Conjunction

Abstract

A joining part is used for combining a first component and a second component awaiting combining, wherein, the first component is congruent on the second component and the first component and the second component are respectively provided with a corresponding opening hole. The joining part comprises an elastic coil, an extending wire rod and a hook stop part. The elastic coil is provided with a first end and a second end the external diameter of which is at least bigger than the opening of the second component, so the second end keeps pressing the bottom face of the second component. The extending wire rod extends to the second end passing through the elastic coil from the end part of the first end of the elastic coil. The hook stop part is formed out of the second end by the extending wire rod passing through the elastic coil and the outline dimension of the hook stop part is at least bigger than the diameter of the first opening to catch the top face of the first component.

Description

technical field [0001] The present invention relates to a combination piece, and more particularly, to a combination piece that penetrates two devices and uses elasticity to combine the two devices. Background technique [0002] see figure 1 , the cooling block 10 is used to contact the central processing unit 12 arranged on the circuit board 11, the cooling block 10 has an opening 101, and the circuit board 11 has an opening 111 slightly smaller than the opening 101, which can pass through The coupling piece 13 assembled with the spring 14 combines the heat dissipation block 10 with the circuit board 11. The top end of the coupling piece 13 has a pressing head 130, and the lower end has a hole 101 which can penetrate the hole 101 but the circumference is slightly smaller than the The stop flange 131 of the opening 111, the spring 14 is sleeved between the pressing head 130 and the stop flange 131, by making the stop flange 131 penetrate the opening 111, and pass through T...

AI Technical Summary

Problems solved by technology

[0004]However, the process of assembling the spring 14 to the joint 13 must overcome the elastic force and there is a certain difficulty in assembling, which results in time-consuming and laborious assembly of the two

[0005] In addition, the spring 14 and the joint 13 are manufactured separately, and two production lines must be set up, which will increase the cost of the manufacturing process and increase the burden of material management

[0006] In addition, under long-term use, the plastic joint 13 is supported by the elastic force of the spring 14 and is prone to damage, resulting in low durability of the joint 13 shortcoming
