Abstract: A resistance-limited electrical interface includes a printed wiring board, a bus bar, a U-shaped conductor, and a retainer. The bus bar extends from the printed wiring board. The U-shaped conductor has a first wall and an opposed second wall, the bus bar arranged between the first and second wall to define a conductive joint between the first wall and the bus bar. The retainer is compressively seated between the second wall and bus bar opposite the conductive joint to exert force on the bus bar for retaining the bus bar in the U-shaped conductor and limiting electrical resistance of the conductive joint.
