Abstract
Abstract Strip supply lead comprising a plurality of conductors embedded in a suitable insulating material (typically, a plurality of generally flat conductor elements in a strip of suitable polymeric material) is provided with a branch lead by first removing a portion of the insulating material in a zone intermediate the ends of the strip supply lead to expose a length of at least one of the conductor elements. The strip supply lead is folded about the midpoint of the bared conductor into a generally "U" shaped configuration to bring the surfaces of the portions on the intact strip supply lead immediately adjacent either end of the bared length of conductor forming the extremities of the shank of the "U" into an opposing relationship. A film of thermoplastic or thermosetting material is disposed between the opposed surfaces of intact strip supply lead and heated above the softening or thermosetting point to cause these surfaces to adhere together thereby forming a generally "U" shaped branch lead in which the bared length of conductor provides the point for electrical contact.
