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.

A method of forming a jumper cable having a plurality of spaced metallic conductors, each of said conductors including a pair of spaced, relatively rigid ends, and at least one region of relative flexibility between said ends and integral therewith, wherein said ends (1) are generally flat, (2) are thicker in cross-section than said at least one region of flexibility, and (3) derive their relative rigidity be virtue of their relative thicker cross-section, said method comprising the steps of: (A) providing a relatively rigid metallic sheet of a cross-section thickness substantially equal to that required for said rigid ends; (B) selectively reducing portions of said metallic sheet in cross-section so as to (i) increase the relative flexibility of said sheet at said region, and (ii) define in situ a plurality of spaced conductors; and (C) covering said spaced conductors at least in part with a flexible insulating material while maintaining said conductors in spaced relation to one another.
