  • Publication number: 20180068760
    Abstract: In a compound type conductive wire structure 1, a plurality of wire-stranded portions 3 are provided to constitute main wire-twisted portions 5 embedded in an insulator matrix 2. Each of the wire-stranded portions 3 has a subsidiary wire-stranded portion 4 to serve as a diameter-reduced wire-twisted portion 8. Such is the structure that it enables to provide a flexibility, pliability and high strength with a diameter-increased wire-twisted portion 10, while securing a friction-resistant, vibration-resistant, impact-resistant and yet excellent bending capability. It is possible to prevent the main wire-twisted portions 5 from coming loose when removing a plastic layer coated over the main wire-twisted portion 5. The core wire 9 has a curved surface 9a which partly engages in surface-to-surface contact with the diameter-reduced wire-twisted portion 8. This makes it possible to evenly disperse stresses applied to the curved surface 9a of the core wire 9.
