  • Patent number: 11955256
    Abstract: A signal transmission cable is provided with a conductor, an insulator covering around the conductor, a shield layer covering around the insulator, a sheath covering around the shield layer, and a plating base layer is provided between the insulator and the shield layer to cover around the insulator. The shield layer has a plating layer provided to cover the plating base layer to be in contact with an outer peripheral surface of the plating base layer. A surface roughness of an outer peripheral surface of the plating layer is less than a surface roughness of an inner peripheral surface of the plating layer.

  • Publication number: 20240097343
    Abstract: A leaky cable is provided with a linear insulator and a metal layer formed on an outer peripheral surface of the insulator. A slot for leaking electromagnetic waves is formed through the metal layer between an inner peripheral surface and an outer peripheral surface of the metal layer, and the outer peripheral surface of the insulator is formed with unevenness that inhibits misalignment of the slot with respect to the insulator. The method of manufacturing the leaky cable includes forming an insulator composed of thermoplastic resin in a cylindrical shape, roughening an outer peripheral surface of the insulator, forming a metal layer on the outer peripheral surface of the insulator, and forming a slot through the metal layer between an inner peripheral surface and an outer peripheral surface of the metal layer. The slot is configured to leak electromagnetic waves to outside of the metal layer.

  • Patent number: 11848119
    Abstract: A high frequency signal transmission cable includes a conductor, an insulator provided over a periphery of the conductor, a plating layer provided over a periphery of the insulator, and a sheath provided over a periphery of the plating layer. A crack suppressing layer includes a non-cross-linked polyethylene is provided between the insulator and the plating layer, in such a manner as to remain in contact with the insulator while being provided with the plating layer over an entire periphery of a roughened outer surface of the crack suppressing layer. The crack suppressing layer is unadhered to the insulator. The plating layer is adhered to the crack suppressing layer. The crack suppressing layer suppresses an occurrence of a cracking in the plating layer by bending together with the plating layer while being integral and moving with the plating layer in a longitudinal direction of the cable.
