Composite cable with built-in signal and power cables
First Claim
1. A composite cable comprising:
- at least two unconnected power cables provided in a center of said composite cable, said at least two unconnected power cables each having a large conductor size;
a flat signal cable unconnected to said at least two unconnected power cables and spirally wound around and directly contacting said at least two unconnected power cables into a roll; and
a non-shielding sheath provided around and directly contacting said flat signal cable.

Abstract
A composite cable with built-in signal an power cables is mainly used as a control cable for a machine tool and the like. The composite cable contributes to reduced cost, downsizing, higher reliability and higher safety, which are obtained because only a single cable needs to be laid, instead of the conventional cable, which requires multiple cables to be laid. In the composite cable with the built-in signal and power cables, a flat signal cable formed by a plurality of insulating cores arranged in parallel in the lengthwise direction, and having alternately repeated combined portions and separate portions is spirally wound into a roll around one or more power cables provided in the center of the composite cable. The power cables each have a large conductor size. A first shield is optionally provided around the flat signal cable. A second shield is optionally provided around the power cables. A sheath is provided around the flat signal cable or the first shield.
