Publication number: 20250087915Abstract: A connector-attached cable includes a cable including a plurality of coaxial wires; and a connector connected to the cable, the connector includes a circuit board and a ground bar connected to the coaxial wires, each of the coaxial wires includes a center conductor, an insulating layer covering the center conductor, an outer conductor covering the insulating layer, and a jacket covering the outer conductor. The plurality of coaxial wires are divided into a first group and a second group. A center line of each of the plurality of coaxial wires along an axial direction thereof is disposed in a manner of not overlapping the outer conductor of another coaxial wire. The ground bar is implemented by a single member, and the outer conductors of all of the coaxial wires are connected to the ground bar.Type: ApplicationFiled: September 2, 2024Publication date: March 13, 2025Applicant: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Naoshige YOKOTA, Takami SAGISAKA, Nobuyuki YAMAZAKI, Wataru SAKURAI

Publication number: 20250087948Abstract: A connector-attached cable includes a cable including a plurality of electronic wires; and a connector connected to the cable. The connector includes a circuit board, each of the electronic wires includes a conductor and an insulating layer covering the conductor. The plurality of electronic wires is connected to the circuit board. The plurality of conductors is connected to a first surface and a second surface of the circuit board. An overlapping width between an electronic wire pair in a first group connected to the first surface and an electronic wire pair in a second group connected to the second surface is smaller than a diameter of the electronic wire. When a distance between center lines of two of the electronic wires is set as S, and a diameter of the insulating layer of the electronic wire is set as d, a relationship of S?0.35d is satisfied.Type: ApplicationFiled: September 9, 2024Publication date: March 13, 2025Applicant: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Naoshige YOKOTA, Takami SAGISAKA, Nobuyuki YAMAZAKI, Wataru SAKURAI

Patent number: 11116073Abstract: A connector-cable module includes a multicore cable including first, second, and third signal lines; and a connector connected to one end of the multicore cable and including a board and first, second, and third pads connected to the first, second, and third signal lines and provided on the board. A first signal and a second signal transmitted through the first and second signal lines form a differential signal. The connector is configured such that when a line passes through a first gravity center of the first pad and a second gravity center of the second pad, a foot of a perpendicular drawn from a third gravity center of the third pad to the line is located between the first gravity center and the second gravity center.Type: GrantFiled: January 30, 2020Date of Patent: September 7, 2021Assignee: SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventors: Naoshige Yokota, Masaki Suzuki
