Abstract

An electric junction box installed in an automotive instrument panel incorporates the meter board and its associated switch circuits as the internal circuit of the box. The electric junction box has an internal busbar circuit having branches that are directly connected to the meter board and the switch circuits so that they form an integral part of the internal circuit of the junction box.

Claims

1. An electric junction box installed inside an instrument panel of an automobile comprising:

branch circuits provided to an internal circuit of the electric junction box, the branch circuits being directly connected to circuits of a meter-carrying meter board and of at least one switch mounted adjacent to the meter board wherein the meter board and the switch are directly mounted to the electric junction box.

2. An electric junction box as claimed in claim 1, wherein the internal circuit of the electric junction box including the branch circuits comprises a plurality of busbar circuit boards stacked one on the other, the busbar circuit boards each comprising an insulating board and busbars of desired patterns formed thereon.

3. An electric junction box as claimed in claim 1, wherein the branch circuits are connected to the meter board via a connector provided on a wall of the electric junction box on which the meter board is integrally mounted.

4. An electric junction box as claimed in claim 1, wherein said at least one switch is integrally mounted on the wall of the electric junction box via a connector provided thereon through which the branch circuits are connected to the switch.
