Abstract:
1. A bus bar assembly comprising: a resinous body; a first bus bar to which electrode terminals of semiconductor modules of an electric power converter are to be connected electrically, said first bus bar being made of a conductive plate which includes a plate body and a plurality of connecting terminals extending from the plate body substantially in parallel to a major surface of the plate body to establish electric connections with the electrode terminals of the semiconductor modules, at least a portion of the body plate of said first bus bar being disposed inside said resinous body, said resinous body having an exterior seat surface that extends in parallel to the major surface of the plate body of the first bus bar; and a second bus bar to which electrode terminals of the semiconductor modules of the electric power converter are to be connected electrically, said second bus bar being made of a conductive plate which includes a plate body and a plurality of connecting terminals extending from the plate body substantially in parallel to a major surface of the plate body to establish electric connections with the electrode terminals of the semiconductor modules, the plate body of said second bus bar being seated on and fixed to said exterior seat surface of said resinous body so that said second bus bar extends in parallel to said first bus bar at a given distance spaced away from said first bus bar.
