Flat cable and method for its manufacture
First Claim
1. A flat cable, wherein a flexible insulation sheath (3) having an exterior surface is used for enclosing at least one metal conductor (2) which is substantially flat and includes conductor bend sections having bends forming a zigzagging configuration that make said at least one metal conductor (2) longer than the insulation sheath (3) enclosing said at least one metal conductor so as to enable a substantial change in said at least one metal conductor length without breaking said at least one metal conductor, characterized in that said at least one metal conductor (2) is provided at certain distances with straight conductor sections (6), which are located substantially closer to said exterior surface of the insulation sheath with respect to the median of said flat cable.

Abstract
A flat cable having a metal conductors enclosed by a flexible insulation sheath. The conductors are flat and in a side by side orientation in the lateral direction and the conductors are provided with bends which enable a substantial increase in the length of the conductors upon extending the insulation sheath without breaking the conductors. The conductors are also provided at certain distances with short straight conductor sections that are oriented closer to the external surface of the flexible insulation sheath. The insulation sheath is constituted by an inner insulation which surrounds the conductors and a harder, outer insulation which serves as an actual protective cable sheath.
