Publication number: 20240097343Abstract: 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.Type: ApplicationFiled: August 25, 2023Publication date: March 21, 2024Inventors: Hideyuki SAGAWA, Takahiro SUGIYAMA, Izumi FUKASAKU, Yasunori TAKAKI, Nobuaki KITANO, Shuichi NUMATA

Patent number: 11848119Abstract: 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.Type: GrantFiled: October 23, 2020Date of Patent: December 19, 2023Assignee: PROTERIAL, LTD.Inventors: Detian Huang, Yoshinori Tsukamoto, Masashi Moriyama, Hideyuki Sagawa, Takahiro Sugiyama
