  • the second connecting portion 53 of the second supplementary electric wire 50 is connected to the second exposed plane 227A by welding (for example, ultrasonic welding). According to this configuration, since the surface to be welded is a flat surface, it is easy to weld.
  • the electric wire constitutes the high-voltage line and the conductive pipe constitutes the low-voltage line, but the electric wire may constitute the low-voltage line and the conductive pipe constitutes the high-voltage line.
  • the conductive pipe does not need to have an inner insulating layer.
  • the conductive pipe does not need to have an outer insulating layer.
  • the wire harness does not need to include an exterior member.
  • the wire harness does not need to include a waterproof member.
  • the color of the outer insulating layer does not have to be a color that indicates that a high voltage line is installed.

Abstract

L'invention concerne un faisceau de câbles qui, dans une configuration dans laquelle un câble haute tension et un câble basse tension s'étendent parallèlement, permet de supprimer les effets sur le câble basse tension des ondes électromagnétiques produites par le câble haute tension. Un faisceau de câbles (W) comprend un câble électrique (10) et un tuyau conducteur (20). Le tuyau conducteur (20) possède une forme de tube qui recouvre la périphérie externe du câble électrique (10). Un parmi le câble électrique (10) et le tuyau conducteur (20) constitue un câble haute tension, et l'autre constitue un câble basse tension. Le faisceau de câbles (W) comprend en outre un élément tubulaire de blindage (30) qui recouvre la périphérie externe du câble électrique (10) et qui est interposé entre le câble électrique (10) et le tuyau conducteur (20).
