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 involves a combination, and more specifically, it involves a combination of a combination of two components that penetrates two components and uses elasticity. Background technique [0002] See figure 1 , The hedema block 10 system is used to contact the central processor 12 on the circuit board 11. The heat sink 10 has an open hole 101, and the circuit board 11 has the opening of the hole 111 slightly smaller than the opening 101.The assembly with a spring 14 is combined with the heat sink 10 on the circuit board 11. The top at the top of the conjunction 13 has the suppression of the head 130 and the lower end.Open holes 111 stopping bump 131, the spring 14 series is set between the suppressing head 130 and the stop block convex margin 131.The pressing head 130 squeezes the spring 14 to the stop -blocking structure posing at the top of the opening 101 or in the opening 101, and combines the heat sink 10 to the circuit board 11.

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
