  • Patent number: 10319495
    Abstract: A conductive path includes: a first conductor in which a terminal end portion serves as a first connection portion; a second conductor in which a second connection portion at a terminal end portion is coaxially fixed to the first connection portion; a support member that is more rigid than the first and second conductors, and is disposed so as to extend along a fixed portion between the first and second connection portions; and a heat-shrinkable tube (holding member) that integrates the support member with the first and second conductors while enveloping the support member. Even when an external force acts on the first and second conductors so as to skew the axes of the two conductors, the support member and the heat-shrinkable tube keep the two conductors in the coaxial state.

  • Patent number: 10320165
    Abstract: A shielded conduction path that makes it possible to reduce the diameter of a portion where a braided wire is fixed to a pipe. The shielded conduction path includes a pipe that has a shielding function, reduced diameter portions that are formed in the outer circumference of the pipe, braided wires that have a shielding function and are arranged such that the base end portions thereof envelop the outer circumference of the reduced diameter portions, crimp rings that are arranged so as to envelop the outer circumference of the base end portions of the braided wires and fix the braided wires to the reduced diameter portions, and a conduction path main body that is inserted into the pipe and into the braided wires.

  • Patent number: 9809180
    Abstract: An electric wire sheathing member including a resin pipe with which springback can be suppressed, and a wire harness are provided. The electric wire sheathing member includes a resin pipe that has a tubular shape into which an electric wire can be inserted and that is bent into a predetermined shape, and a metal body that is integrally provided in at least a bent portion of the resin pipe and continuously extends in the axial direction. With this configuration, the rigidity of a bent portion of the resin pipe is increased by the metal body, thus making it possible to suppress the springback of the resin pipe.

  • Publication number: 20170154709
    Abstract: An electric wire sheathing member including a resin pipe that can be easily attached to a vehicle, and a wire harness are provided. The electric wire sheathing member includes a resin pipe, the resin pipe including a straight tube portion that has a tubular shape into which an electric wire can be inserted and whose cross-sectional shape is constant in an axial direction, a bellows portion that has a tubular shape into which the electric wire can be inserted and in which ridge portions and valley portions are repeated in an axial direction, and a bent portion that is formed by bending the straight tube portion into a predetermined shape. With this configuration, the straight tube portion is not flexible like a corrugated tube having a bellows shape is, and therefore, the shape of the bent portion is retained. Accordingly, the wire harness can be easily attached to a vehicle.
