<p>The present invention relates to flex cables, and more particularly to a temperature tolerant cover layer construction for a flex cable. In one embodiment, a flex cable designed to be bent to a particular curved shape includes one or more slits formed in the inner cover layer, to reduce the amount of material in the cover layer on the inside radius of the curve. By reducing the amount of cover layer material on the inside of the curve, the slits reduce the compressive stress in the cover layer. The slits are formed prior to laminating the flex cable so that upon lamination the flexible filler material below the cover layer fills the slits, providing a compliant, protective layer that bends into the desired curve and protects the active components inside the cable. The slits reduce the compressive stress along the inside cover layer and thereby prevent the cover layer from separating from the rest of the cable when the flex cable is subjected to high temperature conditions.</p> |
