を介して半田付は固定されている。On the other hand, the printed circuit board (6) is formed with an insertion hole (7) into which the burring portion (2) of the bus bar (1) is inserted. The height of the burring part (2) is set approximately equal to the thickness of the printed circuit board (6) in the illustrated conventional example, and in the inserted state shown in FIG.
The protruding end surface is connected to the copper foil pattern (10) of the printed circuit board (6).
) side surface is understood to be approximately the same plane. The bus bar (1) has a copper foil pattern (8) on the printed circuit board (6).
The soldering is fixed through.

いう欠点があった。However, according to this fixing method, the bus bar (
The burring part (2) of 1) has a tapered shape to improve soldering properties with each lead terminal (4).
It is soldered near the tip of the taper. Therefore, the reliability of the electrical connection between the bus bar (1) and the solder (9) is poor, and there is a limit to the reduction of impedance. In general, the shape and fixing method of the bus bar (1) is mechanically weak and unsuitable for passing a large current. In addition, the bus bar (
1) is fixed by soldering to the printed circuit board (6) via the copper foil pattern (8), but forming the copper foil pattern (8) only for the purpose of fixing the bus bar (1) is cumbersome. This has the disadvantage that the process becomes longer and goes against the reduction in manufacturing costs.

ある。In the figure, (1) shows a bus bar having a burring part (21), (3) shows a circuit component, and (6) shows a printed circuit board. (7) is an insertion hole drilled in the substrate (6) into which the outer shape of the bar ring part (21) of the bus bar (1) can smoothly enter, and the bus bar (1) is fitted into the insertion hole (7). The burring portion (21) has an external shape that allows the burring to be inserted, and has a burring length that does not extend to the other surface of the substrate (6) during insertion. (4) The external shape is divided into two stages by the beam terminal,
The tip is thin, its outer shape is slightly thinner than the inner diameter of the bar ring part (21) of the bus bar (1), and the length is the same as that of the circuit component (3
) is inserted into the printed circuit board (6) via the bus bar (1), the thin outer part (42) has a length that does not come out on the opposite board surface, and the terminal (4) that can be inserted or inserted. Insert the bus bar (1) into one side of the printed circuit board (6) by inserting each part consisting of a thick outer part (41) which has a function of a stopper that hits the board surface at the thick part and limits the insertion dimension. After inserting the lead terminal (4) of the circuit component (3) from above the bus bar and tightening it, the bus bar side is fixed by dipping it in molten solder. (91) is solder.

The temperature of the printed circuit board and bus bar increases during solder immersion, and after cooling, distortion may occur due to the difference in coefficient of expansion between the printed circuit board and the bus bar. In addition, burring processing of bus bars requires a large number of man-hours and special equipment is required for the processing.

This completely prevents warping, significantly improves workability, and improves electrical and mechanical reliability. Additionally, since the busbar is mounted floating above the board, thermal reliability is improved and a large current can flow. Furthermore, there is no need to provide a bar ring part on the bus bar, and there is no need for a copper foil pattern for fixing the bus bar to the board, which simplifies work, significantly improves productivity, and expands the range of applications.

Using a tool, press both ends of the nutcer (12) to the center to form the first caulking, and finish fixing it to the first structural member (60). Next, the nut sir (12) fixed to the first structural member (60)
) to the second structural member (60) at the second caulking part (12
Insert the nut until it hits c) and use the special tool to tighten the nut.
Both ends of (12) are pressed to the center to form a second caulking, and the second structural member (60) is fixed to complete the fixing work.
この方法によれは、第１のカシメ部（１２ａ）と第２の
カシメ部（１２ｃ）の板厚に差があるため同時にカシメ
が行われることがなく所望の効果が得られる。With this method, since there is a difference in the thickness of the first crimped part (12a) and the second crimped part (12c), the desired effect can be obtained without crimping being performed at the same time.
