Patent: Highly Flexible Torsion-Resistant Robot Cable with Dual Shielding
A recently published patent (CN224328514U) reveals a highly flexible torsion-resistant robot cable design incorporating metal spring wire in the shielding layer to enhance flexibility and torsional resistance .
Key Innovations:
Ultra-fine silver-plated copper conductors: Stranded with first and second fiber reinforcing cores
Elastic support strips: Made of rubber material embedded in insulation layer for continuous support during bending and torsion
Dual shielding: Aluminum foil plus tin-plated copper braid with spiral metal spring wire
Carbon fiber filling strips: Filling layer with carbon fiber strips to enhance torsional resistance
Polyurethane elastomer outer sheath: With fiberglass reinforcing ribs and anti-slip texture
Engineering Significance: The design addresses the fundamental challenge of maintaining insulation integrity and conductor stability under extreme torsional stress, with a buffer layer featuring multiple hollow rubber cylinders evenly distributed circumferentially .
