関するものである。Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a method for mechanically fixing and electrically connecting a press-fitting portion of a terminal by press-fitting an electrical conductor terminal into a null-hole portion of a printed wiring board. The present invention relates to a structure and a method of manufacturing the terminal.

ものがあった。Conventionally, in this type of terminal, the structure of the part that is press-fitted into the through-hole part of the printed wiring board is: firstly, a hollow hole is provided to form a beam structure, and secondly, a metal plate is cut and bent. The third type of beam structure was an accordion structure with a cross-sectional shape such as M, W, N, or V, and the fourth type was a so-called split bottle structure with a U-groove in cross-section and an arcuate outer shape. .

ホール内で端子が滑って回るおそれがある。However, in the conventional structure described above, the following five problems occur.
There was a drawback. First of all. In the second conventional structure, hollow hole machining or cutting and bending machining makes it difficult to downsize, and therefore it is difficult to achieve high-density mounting of electronic parts on the printed wiring board. In addition, in the sixth conventional structure, the part that comes into contact with the through hole is a limited and small part, so in order to obtain the necessary mechanical fixing force after press-fitting, a large force must be applied to the small part of the through hole. As a result, there is a risk of through-hole crushing damage. Further, in the fourth conventional structure, since the outer shape is an arc, there is a risk that the terminal may slip and rotate within the through hole due to the torque applied to the terminal when, for example, winding or wiring is applied to the terminal after press-fitting.
本発明の目的は、スルーホールな圧潰破損することなく

徴とする。According to the present invention, the cross-sectional shape of the press-fitting part of the terminal is U-shaped on the inside, and has a plurality of circular arc parts and a plurality of straight parts on the outside, so that the cross-sectional shape of the press-fitting part of the terminal is formed into a U-shape, and the outside has a plurality of circular arc parts and a plurality of straight parts. is characterized by a configuration in which the connection is stabilized by concentrating the force in the radial direction at a plurality of circular arc parts.

In addition, in Fig. 5, it was explained that the three press dies were operated independently to speed up understanding, but for example, the six press dies shown in Fig. 5(a) to <cr are operated in the feeding direction of the metal plate M. The press drive system can be further simplified by arranging the six Brene rollers in parallel at a position four times the pitch between the terminals δα (n is an integer of 1 or more) so that they can operate simultaneously.

とれる。According to the present invention, force is concentrated at a plurality of partially arcuate portions at the contact portion between the terminal and the inner wall of the null hole, so that mechanically strong fixation and electrically stable connection can be obtained. . In addition, since the contact area for the inner wall of the through-hole and the arc of the contact area of the terminal are almost concentric, the contact surfaces fit well with each other, and even if force is concentrated, the conductor on the inner wall of the through-hole will not be crushed and damaged, increasing reliability. On the other hand, the cross-sectional shape is based on U-groove formation, which is a specialty of micro-press processing, so it is fully compatible with miniaturization.
