Internal power bus and power output assembly
The present invention relates to a power distribution unit with output power terminals and electrical leads with mating portions connected to extensions of the terminals, with adjacent mating portions and connected extensions offset from one another. Alternatively, an electrical power unit may have one or more power output terminals connected to a corresponding number of power distribution circuits by leads, each lead having a portion parallel to and offset from other adjacent leads in a first direction and another portion parallel to and offset from each adjacent lead in a second direction. The present invention further relates to an output power assembly with inner and outer faces, a first set of terminals on the outer face which are electrically connected to a common conductor along the inner face and a second set of terminals each having individual connectors along the inner face, the individual connectors being offset from each adjacent connector.
