Strip supply lead with branch leads and method of making same

A method for providing strip supply lead, comprising a plurality of conductor elements embedded in an insulating material, with a branch lead comprising the steps in sequence.

• A. removing a portion of the insulating material in a zone intermediate the ends of the strip supply lead to bare a length of all the conductor elements;
• B. folding the bared lengths of said conductor elements around an insulating core of generally U-shaped cross-section to bring the surfaces of portions of the intact strip supply lead immediately adjacent either end of the bared conductor elements forming the extremities of the shanks of the U into an opposed relationship;
• and
• C. bonding the opposed surfaces of intact strip supply lead to each other to form a generally U-shaped branch lead in which the bared lengths of conductor elements provide electrical contacts.

A method for providing strip supply lead, comprising a plurality of conductor elements embedded in an insulating material, with a branch lead comprising the steps in sequence:

• A. removing a portion of the insulating material in a zone intermediate the ends of the strip supply lead to bare a length of all the conductor elements;
• B. folding the bared lengths of said conductor elements about an insulating core of generally U-shaped cross-section to bring the surfaces of portions of the intact strip supply lead immediately adjacent either end of the bared conductor elements forming the extremities of the shanks of the U into an opposed relationship;
• and
• C. bonding the opposed surfaces of intact strip supply lead directly to each other by heating the insulating material on the opposed surfaces to render it tacky and pressing the surfaces together to form a generally U-shaped branch lead in which the bared lengths of conductor elements provide electrical contacts.
