Abstract: An electrical jumper cable comprising a plurality of spaced metallic conductors is formed from a rigid metallic sheet by selectively reducing the sheet in cross-section so as to define conductor patterns and integral terminal ends, and to render flexible areas of the conductors. The metallic conductors are laminated to flexible insulating films which support the conductors and maintain the conductors in spaced relation to one another.

Abstract: An electrical jumper cable comprising a plurality of spaced metallic conductors, each conductor having a flexible area and integrally formed rigid terminal ends, is provided. Starting with a metallic sheet having a thickness approximating that required for the conductor flexible areas, one or more mesas of thickness approximating that required for the terminal ends are formed on the edge regions of the sheet. The mesas may be formed by plating or casting so that the thickened edge regions are integral with the sheet central region. The resulting substrate is then chemically or mechanically milled so as to define the conductor patterns and terminal ends, and the metallic conductors laminated to flexible films so as to support and maintain the metallic conductors in spaced relation to one another.
