−メス中継端子、ｍはタブ挿通孔を示す。FIG. 15 shows an example of such an electrical junction box, in which wiring board assemblies e 1 , e 2 ... Composed of a plurality of bus bars c and insulating substrates d are stacked and housed in an upper case a and a lower case b. Then, the tabs (connection terminals) f formed so as to rise above or below the bus bar c are made to protrude into the connection portions such as the connector receiving portion g 1 and the fuse insertion portion g 2 provided in the case, and here the wire harness W The terminal connector h, fuse i, relay j, and circuit breaker k are combined.

ような小電流回路では過大の電流容量をもつことにな
り、回路構成の高密度化を妨げている。The method of forming the internal circuit with the bus bar c has an advantage that it can be formed by punching and bending a single thin metal plate (for example, brass plate). Since the busbar plate thickness is constant, the busbar width is changed to correspond to the current value for each circuit. However, since the bus bar width is also regulated by the mechanical strength, it cannot be made extremely thin.For this reason, a small current circuit such as a signal line will have an excessive current capacity, resulting in a high circuit configuration. Prevents densification.

It is proposed to handle branch connections. A tab f of the bus bar c and a group of terminals o implanted on the printed circuit board n are projected individually or in combination in the connector receiving portion g 1 and are combined with an external connector or the like.

Even if the printed circuit board n is used together with the bus bar circuit as shown in FIG. 16, it is difficult to take out the tab f group and the terminal o group due to competition, so increase the number of bus bars and the number of printed circuit boards. There are limits to increasing the density of internal circuits.
