A wire harness includes: an electrical wire including a core wire and an insulating covering for covering the core wire; and a sheet material in which the electrical wire is disposed on a resin main surface, and a part of the main surface having contact with the electrical wire is thermally processed with the insulating covering of the electrical wire, thereby forming an electrical wire fixing part. A part of the sheet material including the electrical wire fixing part is softer than the insulating covering.

Wire harness and method of manufacturing wire harness

A wiring harness includes an electromagnetic shield and a high-voltage electric wire. The electromagnetic shield includes a metal pipe and a braided member, which is continuous with the metal pipe and includes metal strands. The high-voltage electric wire extends through the metal pipe and the braided member of the electromagnetic shield. The high-voltage electric wire is electrically connected to an automotive high-voltage battery and includes an insulative coating. The high-voltage electric wire includes a braided protector and a resin protection tube. The braided protector is formed by a braid of insulative reinforced fibers and surrounds the insulative coating. The braided protector of the high-voltage electric wire extends from a portion located inside the metal pipe to a portion surrounded by the braided member. The protection tube of the high-voltage electric wire surrounds a portion of the braided protector located inside the braided member.

Wiring harness

A vehicular high-voltage wire that can suppress short-circuiting between a positive wire and a negative wire that are connected to an in-vehicle high-voltage battery. A wire harness includes a positive high-voltage wire and a negative high-voltage wire that are connected to an in-vehicle high-voltage battery. The positive high-voltage wire includes a core wire that is made of a conductor and is for electrical connection to the high-voltage battery, and a protection member that is constituted by woven reinforced fibers that have an insulation property, and is shaped as a tube that surrounds the outer circumference of the core wire.

Vehicular high-voltage wire and wire harness

A flame-retardant electric wire coating material composition that can improve heat resistance without using electron beam cross-linking, has no risk of reducing the mechanical characteristics and chemical resistance due to no metal hydroxides being added thereto as flame retardants, and can suppress the formation of die lip build-up and the like during manufacturing to achieve favorable productivity, and an insulated electric wire and a wire harness. The electric wire coating material composition may include:

Electric wire coating material composition, insulated electric wire, and wire harness

A resin composition for a wire covering material that is excellent in high-temperature oil resistance, wear resistance, and elongation, and an insulated wire and a wiring harness in which the resin composition for a wire covering material is used as the covering material contains a (A) polysulfone-based resin, a (B) aromatic polyester resin, a (C) polyester elastomer, and a (D) compound having a reactive functional group that reacts with one of a carboxyl group and a hydroxyl group, wherein the (D) component reacts with the (B) component or the (C) component to form a bond.

Resin composition for wire covering material, insulated wire, and wiring harness

An insulating coated wire includes a center conductor and an insulating coating. The insulating coating has a bending auxiliary section in which the thickness of the insulating coating is smaller than that of the other portion, and that has a shape in which at least a part thereof protrudes outward in the radial direction. The bending auxiliary section has a shape that facilitates bending of the insulating coated wire by elongation deformation thereof. This insulating coated wire can be manufactured by arranging, on the circumference of an insulating coated wire material, a metal mold that has the inner surface including the section having a shape protruding outward in the radial direction, and forming the bending auxiliary section in the shape along the inner surface of the metal mold by heating the insulating coating within the metal mold and generating a pressure difference between inside and outside of the insulating coating.
