  • Publication number: 20240145122
    Abstract: An insulated electric wire containing a conductor having a flat shape and showing excellent selectivity for bending in the height direction of the flat shape, and a wiring harness containing such an insulated electric wire. An insulated electric wire contains a conductor and an insulation cover covering an outer periphery of the conductor. The conductor contains a flat portion which has a flat shape, in a cross section perpendicular to an axial direction of the conductor, having a larger size in a width direction than in a height direction. In the flat portion, a flexural rigidity in the width direction x of the insulated electric wire is 2.6 times or more than a flexural rigidity in the height direction y. The wiring harness contains the insulated electric wire.

  • Publication number: 20240145123
    Abstract: An insulated electric wire includes a flat portion and a low-flatness portion along an axial direction x, having elemental wires constituting a conductor and an insulation coating being continuous with one another. An outer shape of the conductor of the flat portion in a cross-section perpendicular to the axial direction x of the insulated electric wire takes a flat shape, and an outer shape of the conductor of the low-flatness portion takes a shape with flatness lower than the flat portion. In each of the cross-sections of the conductor of the flat portion and the low-flatness portion, deformation ratios of the elemental wires from a circle at width directional end parts, which corresponds to regions facing an outer periphery of the conductor at both ends of the flat shape in a width direction, are lower than the deformation ratios of the elemental wires at a center parts of the conductor.
