Abstract:
An electrical junction box comprising:a casing, and an electrical circuit in said casing adapted to make electrical connection, in use, to electrical connectors, fuses and relays, said electrical circuit comprising a fuse connection circuit, a relay connection circuit and a connector connection circuit, which is electrically connected to said fuse connection circuit and said relay connection circuit, said casing comprising a fuse circuit portion, containing said fuse connection circuit, and a relay circuit portion, containing said relay connection circuit, said casing having two laterally opposite sides at each of which said casing comprises a connector accommodation portion adapted to receive, in use, at least one electrical connector, said electrical junction box further comprising, mounted in said casing, a connector module providing said connector connection circuit and comprising (i) a plurality of insulation substrates stacked one on another and each having a first main surface and a second main surface opposite said first main surface, (ii) a plurality of parallel elongate bus bars arranged on said first main surface of each said substrate and extending in a first direction, and (iii) a plurality of parallel flexible conductors arranged on said second main surface of each said insulation substrate and extending in a second direction orthogonal to said first direction, wherein each said insulation substrate has a plurality of apertures through it from said first main surface to said second main surface, at which said bus bars and said flexible conductors are connected to each other by welding to provide desired circuit connections, and said first direction of said bus bars of each said insulation substrate is the lateral direction of said casing between said opposite sides, at least some of said bus bars extending from said insulation substrates in said first direction and providing tabs projecting into said connector accommodation portions.
