Problems solved by technology
[0005] However, since a terminal for a substrate made of a metal wire has a small cross-sectional area, there is a limit to sufficiently obtain the protrusion amount of the laterally protruding protrusion by forging.
Therefore, there is a problem that it is difficult to sufficiently increase the overlapping margin between the protruding portion and each facing surface of the terminal holding hole, and it is difficult to securely fix the position of the terminals for each substrate on the terminal holder.
In addition, as described in Patent Document 1, although it is conceivable to provide protrusions at multiple locations to improve the stability of position fixation, there is a problem that the manufacturing process becomes complicated and the manufacturing cost increases because the number of times of forging is increased.

Embodiment Construction
[0029] Embodiments of the present invention will be described below with reference to the drawings.
[0030] first, figure 1 In the figure, as a first embodiment of a terminal for a substrate having a structure of the present invention, a terminal for a printed circuit board accommodated in an electrical junction box for an automobile is shown in perspective view. from figure 1 It can be seen that the substrate terminal 10 according to the present embodiment has an elongated quadrangular prism shape as a whole. The terminal 10 for this substrate is formed using a cut wire material obtained by cutting a metal square wire having a terminal holding base 48 which is a terminal holding member made of synthetic resin described later, and is formed by cutting a predetermined length. The terminal holding hole 56 has a similar shape and has a slightly larger rectangular axis-orthogonal cross-sectional shape to the extent that it can be press-fitted into the terminal holding hole 56...

The invention discloses a terminal for a substrate, which has a novel structure and enables a protruding part connected with a terminal retaining hole in pressure manner to protrude to a certain extent by a simple structure. The terminal is formed by cutting off a metal wire material similar with a terminal retaining hole (56) of a terminal retaining element (48) and having a little larger section by a preset length. Furthermore, a pressed part (20) inserted into the terminal retaining hole (56) is forged and pressed orthogonally; protruding parts (32) protruding outwards are arranged on the two sides in an orthogonal direction to the forging and pressing direction; a surface of the pressed part (20) in the forging and pressing direction is used as a forging and pressing surface, and a concave part (36) with an opening is arranged on the forging and pressing surface (34).
Description
technical field [0001] The present invention relates to a terminal for a substrate used to connect a printed circuit board circuit accommodated in an electrical connection box of an automobile to an external circuit, and particularly relates to a terminal holder which is pressed into and held in a synthetic resin terminal holder and used by Terminals for substrates made of metal wires. Background technique [0002] Conventionally, when connecting electrical components to a printed circuit board circuit housed in an electrical connection box or the like of an automobile, a terminal for a board made of a conductive metal material has been used. Such a terminal for a board is press-fitted and held in a terminal holding hole formed through a terminal holder made of synthetic resin such as a terminal base and a connector housing. In addition, one end side of the board terminal is soldered to the conductive path of the printed circuit board, and the other end side is fitted and c...
