合構造の開発が求められる様になつて来ている。(2) Background of the technology Generally speaking, there are two methods for fixing conductive terminals that transmit electrical signals to printed circuit boards: one is to insert the terminal into a through hole and fix it by soldering, and the other is to press it into the through hole and connect it without soldering. However, since the former method involves a soldering process and involves various manufacturing problems, there is an increasing demand for the development of a highly reliable terminal joining structure using the latter method.

なされる。(7) Effects of the invention As explained above, according to the invention, the joint part to be inserted and fixed into the through-hole of the terminal is cut in the center with the holes bored at the upper and lower ends of the joint part as the ends. Since it is formed by forming a notch and V-shaped or U-shaped contact pieces on the left and right sides of the notch, the tips of the two contact pieces are compressed and deformed so that they come into contact with each other, and the joint is formed. By inserting the contact piece into the through hole, the elastic restoring force caused by the deformation of these contact pieces provides reliable electrical and mechanical contact with the through hole, and the connection is achieved without soldering.
