Description

Connection terminal for improving contact point reliability and manufacturing method thereof

The present invention relates to a connection terminal and a method of manufacturing the same, and more particularly to a connection terminal capable of improving the reliability of a contact point and a method of manufacturing the same.

As shown in FIG. 1 and FIG. 2A , the conventional connector W1 is often provided with a single-terminal type connection terminal W2, and it is easy to cause the single-terminal form connection terminal W2 to be lifted and deformed due to an external force, resulting in poor contact. situation.

As shown in FIG. 2A and FIG. 2B, in order to improve the contact failure in the future, the single-terminal form connection terminal W2 is changed to the two-terminal form connection terminal W3, and the two-terminal form connection terminal W3 includes the first contact portion W31 and the The two contact portions W32 are expected to maintain normal contact at one of the first contact portion W31 or the second contact portion W32.

However, the fact is not so ideal, because the two-terminal form connection terminal W3 is subjected to the external destructive force, the first contact portion W31 and the second contact portion W32 will suffer almost the same destructive force, as shown in FIG. Both the contact portion W31 and the second contact portion W32 have almost the same positive force (solid line and broken line of the vertical axis) under the same stress period (horizontal axis), and thus the first contact portion W31 The degree of deformation generated by the second contact portion W32 is also almost the same, and in the above manner, the contact reliability of the terminal cannot be effectively improved.

The reason is that the present inventors have felt the above-mentioned problems, and have devoted themselves to research and cooperated with the application of the theory, and finally proposed a present invention which is rational in design and effective in improving the above-mentioned defects.
