Problems solved by technology
However, the related countermeasures inherently have the following problems. When the soldering part is pressed into the through hole, it will damage the inner layer circuit of the printed circuit board and cause defects such as disconnection of the inner layer circuit, or the inner surface of the through hole may be damaged. It becomes difficult to ensure the connection reliability due to the peeling of the plating and the reduction of the amount of solder improvement

Embodiment Construction
[0045] Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0046] Figure 1-7 A printed wiring board 10 with terminals as one embodiment of the present invention is shown. The printed circuit board 10 with terminals has a structure in which the terminals 12 are erected on the printed circuit board 14 . In addition, in the following description, the longitudinal direction and the vertical direction refer to figure 1 In the upper and lower directions, the width direction refers to figure 1 Middle left direction. In addition, the plate thickness direction refers to figure 1 in the direction perpendicular to the paper.
[0047] The terminal 12 has a flat plate shape, and is formed, for example, by punching a metal plate on which tin plating or the like is applied to the surface, such as a copper plate. A pair of soldering portions 18 and 18 and a fixing leg portion 20 are formed at one end 16 in the longitudinal direction of ...

A printed circuit board with a terminal having a novel structure that enables terminals to stand on their own on the printed circuit board without using a seat, while reducing or eliminating damage to through-hole plating or an inner layer circuit. A printed circuit board with a terminal includes a terminal having soldering sections that are inserted, without being press-fitted, into through-holes of a printed circuit board and are fixed by soldering. The terminal has a fixation leg and the printed circuit board has a press-fit hole, the terminal is positioned and retained on the printed circuit board by the fixation leg of the terminal being press-fitted into the press-fit hole of the printed circuit board, and an inner circumferential surfaces of the through-holes are provided with plating, whereas an inner circumferential surface of the press-fit hole is not provided with the plating.
Description
technical field [0001] The present invention relates to a printed circuit board with a terminal, which is formed by inserting the soldered part of the terminal into a through hole of the printed circuit board without pressing it, and fixing it by soldering. Background technique [0002] Currently, a terminal-attached printed circuit board provided with a plurality of terminals upright is widely used as an internal circuit of an electrical junction box for automobiles. In the printed wiring board with terminals, the soldered portion provided at one end of the terminal is not crimped to a through hole of the printed wiring board, but is arranged in a state of being inserted with a gap therebetween. By soldering the soldered portion inserted into the through hole to the through hole, the soldered portion is connected to the printed wiring of the printed circuit board, and the terminal is fixed to the printed circuit board. In addition, the other end portion of the terminal has...
