Wire harness

摘要

A wire harness includes a plurality of electric wires, a first wire holding portion for holding one of both end portions of the plurality of electric wires, a second wire holding portion for holding another of the both end portions, and an annular electromagnetic wave absorption component arranged between the first and second wire holding portions so as to absorb electromagnetic wave radiated from the plurality of electric wires. The electromagnetic wave absorption component includes a through-hole for inserting collectively the plurality of electric wires such that the plurality of electric wires are inserted through the though-hole and are thereby bundled together.

1. A wire harness, comprising:
a plurality of insulated electric wires, each insulated electric wire having a circular cross section and comprising a center conductor and an insulation covering an outer periphery of the center conductor; a first wire holding portion holding one of both end portions of the plurality of insulated electric wires; a second wire holding portion holding another of the both end portions; and an annular electromagnetic wave absorption component arranged between the first and second wire holding portions so as to absorb electromagnetic wave radiated from the plurality of electric wires, wherein the electromagnetic wave absorption component comprises a through-hole having a circular cross section and configured to receive collectively the plurality of insulated electric wires and the plurality of insulated electric wires are inserted through the though-hole and are thereby bundled together, wherein the plurality of insulated electric wires comprise three insulated electric wires having the same outer diameter, and wherein the outer diameter of the each insulated electric wire is not less than 10% and not more than 46% of an inner diameter of the through-hole, and further comprising, a movement-restricting member configured to restrict the electromagnetic wave absorption component from moving in an axial direction of the plurality of electric wires and covering only the electromagnetic wave absorption member and portions of the plurality of electric wires immediately adjacent thereto such that the plurality of electric wires are substantially uncovered by the movement-restricting member, and a braided shield provided around the plurality of insulated electric wires and the electromagnetic wave absorption component, wherein the movement-restricting member contacts the braided shield at an outer surface of the electromagnetic wave absorption component, contacts the braided shield at an outer periphery of a part in a longitudinal direction of portions of the plurality of the insulated wires exposed from the through-hole on a first wire holding portion side, and contacts the braided shield at an outer periphery of a part in a longitudinal direction of portions of the plurality of the insulated wires exposed from the through-hole on a second wire holding portion side, and wherein the movement-restricting member binds in one bundle only the part in the longitudinal direction of the portions of the plurality of the insulated wires exposed from the through-hole on the first wire holding portion side via the braided shield, and binds in one bundle only the part in the longitudinal direction of the portions of the plurality of the insulated wires exposed from the through-hole on the second wire holding portion side via the braided shield.
