Abstract

Fuse bus bars in a fuse module are provided with press contact terminals that are connected to terminals of each fuse and are disposed closely in parallel with each other. If there are some circuits to be connected and the other circuits to be divided in all circuit specifications in the different kinds of and same kind of automobile vehicles that mount junction boxes, the fuse bus bars constituting the circuits are integrally connected by bridging portions. If the circuits are required to be divided in accordance with the circuit specification of the automobile vehicle mounting the fuse bus bars, an alteration of circuit can be carried out by cutting off the bridging portion.

Claims

1. A junction box comprising:

a connector connection circuit and a fuse connection circuit containable in said junction box are divided into each other in order to form a connector module and a fuse module, respectively, wherein

said circuits in said connector and fuse modules are connected to one another including at least one of connectable circuits and separable circuits;

said connector module includes stacked circuit boards, each circuit board has a first insulation board and connector bus bars secured to said first insulation board, and

said fuse module includes a second insulation board and fuse bus bars that are secured to said second insulation board and said fuse bus bars are connected to fuse terminals, each fuse terminal corresponding to a fuse;

said fuse bus bars in said fuse module having press contact terminals that are connected to said fuse terminals and are disposed closely in parallel with each other;

said connectable circuits are connectable and said separable circuits are separable to produce a specified circuit corresponding to any of all circuit specifications in different kinds of and a same kind of automobile vehicles, each said specified circuit mounts the junction box, said fuse bus bars constituting said connectable circuits being integrally connected by bridging portions, and

said separable circuits are separable in accordance with the specified circuit specification that mounts said fuse bus bars, said specified circuit being alterable by cutting off said bridging portions.

2. The junction box according to claim 1, wherein the fuse bus bars are formed from a sheet of conductive metal plate.

3. The junction box according to claim 1, wherein the fuse bus bars further include tabs that can be cut off.
