Electric junction box

An electric junction box, comprising:

• a power distributor comprising a circuit construct having circuit board mounting relays mounted on a first side of a printed circuit board and bus bars mounted on a second side of said printed circuit board, having a heat sink attached on a side of said circuit construct having said bus bars, said heat sink facing an opening provided in a case of said power distributor;
• a branch circuit module comprising a laminate of bus bars and insulation plates, and including housings for relays, fuses and connectors, the relays, fuses and connectors being connected to said bus bars, the laminate being provided inside said case, and said housings being provided on a side of said case,
• wherein said power distributor is arranged perpendicularly to said branch circuit module along an edge on a side of said branch circuit module, forming a generally L-shaped configuration, and
• wherein terminal portions of said bus bars of said branch circuit module, provided at a corner of said generally L-shaped configuration, are welded to said terminal portions of said bus bars of said circuit construct, said bus bars of said circuit construct being provided perpendicularly to said bus bars of said branch circuit module.

An electric junction box, comprising:

• a power distributor comprising a circuit component having a printed circuit board, at least one relay provided on a first side of said printed circuit board, at least one bus bar provided on a second side of said printed circuit board, and a heat sink provided opposite an opening in a case of said power distributor;
• and
• a branch circuit module comprising a laminate of bus bars and insulation plates, said branch circuit module including a plurality of housings for electrical components, said power distributor and said branch circuit module forming a generally L-shaped configuration,
• wherein said bus bars of said branch circuit module include terminal portions connected to terminal portions of said at least one bus bar of said circuit component;
• and
• wherein said bus bars of said branch circuit module are generally perpendicular to said bus bar of said circuit component.
