  • Patent number: 9545888
    Abstract: A vehicle composite cable includes a pair of power wires for supplying a current to an electric parking brake unit that generates a braking force after stopping a vehicle, a first signal line including a twisted pair wire transmitting a first electrical signal during when the vehicle is in motion, a second signal line including a twisted pair wire for transmitting a second electrical signal also during when the vehicle is in motion, and a sheath collectively covering the pair of power wires and the first and second signal lines. The first and second signal lines are not covered with a shield conductor, and the first signal line is separated from the second signal line by the pair of power wires.
    Type: Grant

  • Patent number: 9350571
    Abstract: A differential signal transmission cable includes: two signal conductors; an insulator for covering these signal conductors; and a shield tape wound around the insulator in longitudinal wrapping. In the differential signal transmission cable, both ends of the shield tape in a direction of the winding around the insulator have a first overlapping region and a second overlapping region which overlap each other, and the first overlapping region of the shield tape is covered with the second overlapping region. In a tangent line of two tangent lines of a first signal conductor which is orthogonal to a line passing through centers of the signal conductors, when the tangent line positioned at radially outside of the first signal conductor is set to be a first tangent line, an end of the first overlapping region is positioned at outside of the first tangent line.
