Abstract

Various structures for and methods of constructing miniaturized high capacitance bus bars are presented. The bus bars incorporate discrete high capacitive elements between a pair of bus bar conductors. In a preferred embodiment, a zebra film comprised of an elastomeric material having alternating strips of conducting and nonconducting material is positioned between the capacitive elements and the bus bar conductors. This zebra structure establishes electrical contact between the capacitive elements while avoiding the development of short circuits between the two bus bar conductors. This zebra structure may also have a mechanical force means applied whereby the applicable conductive surfaces are urged into electrical contact with the elastomeric strip material.
