Abstract
A termination for a flexible circuit having flat conductive strips integrally bonded to a flexible substrate. The conductive strip has a termination portion located adjacent an aperture in the substrate. The termination portion has a connection tab, with the termination portion and the connection tab lying in a plane. The termination is for connection to a conductive element end which extends through the aperture. The connection tab is formed into a shape outside the plane with the connection tab engaging the conductive element where it is secured by welding to the conductive element.
Claims17
A termination for a flexible circuit, said flexible circuit comprising a flexible substrate, a flat conductive strip integrally bonded to said substrate, said termination for connection to a conductive element having an end, said termination comprising:
- said flexible substrate having an aperture therein;
- said conductive strip having a termination portion located adjacent said aperture, said termination portion having a flexible connection tab, said termination portion and said connection tab fabricated in a first plane;
- said conductive element end extending through said aperture;
- said connection tab being formed into a shape with a portion of said connection tab engaging said conductive element and at least a portion of said shape lying outside of said first plane;
- and
- means for securing said connection tab to said conductive element by a weld, with said tab formed in said shape being sufficiently flexible to allow movement of said conductive element relative to said substrate to provide strain relief.
In a flexible circuit of the type having a flat conductive strip bonded to a flexible substrate, said conductive strip having a transmission portion and a termination portion lying in a first plane, said flexible circuit for electrical connection to a conductive element having an end, the improvement in a termination which comprises:
- said flexible substrate having an aperture;
- said termination portion located adjacent said aperture, said termination portion having a flexible connecting tab, with said conductive element end extending through said aperture, and said tab formed at least partially outside of said first plane to meet said conductive element, said tab secured to said conductive element by welding means with said tab being sufficiently flexible to allow movement of said conductive element within said aperture to provide strain relief.
