数の異なる分岐回路を形成することを特徴とする。Means for Solving the Problems In order to achieve the above object, a method for forming a circuit using a bus bar according to the present invention comprises a plurality of tab terminal forming portions branched from a bus bar having a predetermined pattern. When the tab terminal is formed by bending the tab terminal perpendicular to the surface of the bus bar, the unnecessary tab terminal remains on the insulating substrate in a state where the tab terminal forming portion is not bent or cut off from the bus bar after bending. A branch circuit having a different number of terminal poles is formed from a single bus bar having a predetermined pattern and a plurality of front and rear tab terminal forming portions.

ある。1, a bus bar 2, 2 ', 2 "... Having a predetermined pattern is provided on an insulating substrate 1. The bus bar 2 is composed of three bus bars 2 as shown in FIG. Tab terminal
It has 2a, 2b, 2c and one tab terminal formation part 2D. The bus bar 2 initially has four tab terminal forming portions 2A as shown in FIG.
~ 2D are integrally formed by punching from sheet metal in a state of being branched and connected to each other, but the tab terminal forming portion 2D not used as a tab terminal is left as it is, and the other tab terminal forming portion 2A
2C are formed by bending the tab terminals 2a to 2c.

たり脱落する等の心配はない。The above is an example in which the tab terminal 2d is selected as an unnecessary tab terminal, but the same applies to the other tab terminals 2a to 2c, and if necessary, do not bend two or more tab terminal forming portions. Can also. The busbars 2, 2 ', 2 "... Are usually fitted in grooves (not shown) formed in the insulating substrate 1 or fixed with an adhesive. In FIG. 4, there is no fear that the tab terminal 2d cut and separated from the bus bar 2 falls or falls off.
