Abstract

The utility model discloses a composite motion cable for robot dog legs. The outer diameter of the composite motion cable is smaller than 8 mm, each composite core wire is mainly formed by twisting two insulating core wires and wrapping the two insulating core wires with an aluminum foil layer, the tinned copper foil wire woven shielding layer wraps the four composite core wires, the at least one power wire is arranged outside the tinned copper foil wire woven shielding layer, the cotton wire is arranged outside the tinned copper foil wire woven shielding layer, and the outer diameter of the composite motion cable is smaller than 8 mm. The tinned copper foil wire woven shielding layer, the power lines and the cotton threads are wrapped by the wrapping tape layer, and the outer surface of the wrapping tape layer is wrapped by the outer sheath. The robot dog leg flexible cable has good flexibility, wear resistance, signal transmission stability and anti-interference performance, and can meet the requirement of complex movement of robot dog legs.
