It is an object of the exemplary embodiments to obtain a long electric-wire protection pipe having a flat outer shape, using a simple press working process, while reducing or even preventing warping problems. An electric-wire protection pipe is a metal pipe that surrounds an electric wire, and has a reinforced section () and a flat pipe section. The reinforced section is a section that is located at a part in the circumferential direction of the electric-wire protection pipe while extending along the entire length in the longitudinal direction of the electric-wire protection pipe, and that is thicker than other sections. The flat pipe section is a section that constitutes at least a part in the longitudinal direction of the electric-wire protection pipe, and is flattened by press working.

Electric-wire protecting pipe and wire harness

It is an object of the exemplary embodiments to obtain a long electric-wire protection pipe having a flat outer shape, using a simple press working process, while preventing warping problems. An electric-wire protection pipe is a metal pipe that surrounds an electric wire, and has a reinforced section and a flat pipe section. The reinforced section is a section that is located at a part in the circumferential direction of the electric-wire protection pipe, and constitutes a protrusion forming, on either the internal or external surface of the electric-wire protection pipe, a ridge line extending along the longitudinal direction of the electric-wire protection pipe, and a groove extending along the longitudinal direction of the electric-wire protection pipe on the other surface. The flat pipe section is a section that constitutes at least a part in the longitudinal direction of the electric-wire protection pipe, and that is flattened by press working.

Electric-wire protection pipe and harness

An electromagnetic shielding device includes a conductive sheet that is a sheet-shaped flexible conductive member that can be deformed into a tube shape, and an outer edge portion coupling member that keeps the conductive sheet in a tube shape in a state in which a first outer edge portion and a second outer edge portion of the conductive sheet are joined together, the second outer edge portion being located on the side opposite to the first outer edge portion. For example, a parallel slit group is formed in the conductive sheet, the parallel slit group being constituted by a plurality of slits that extend in a direction that crosses a first direction from the first outer edge portion toward the second outer edge portion and that are lined up in the first direction.

Magnetic shielding device and wire harness

A shield conductor is provided with electrical wires and a metal pipe that encloses the electrical wires and whose outer peripheral surface is covered with an orange (color other than a metallic color) resin layer. The pipe is routed so that at least a portion passes in proximity to an exhaust pipe of a vehicle. A section of the pipe passing in proximity to the exhaust pipe that faces the exhaust pipe does not have the resin layer and the metallic-colored outer peripheral surface of the section remains exposed.

Shield conductor

A shield conductor includes: an electrical wire; a tubular shield member that encloses the electrical wire and is configured such that an end portion of a pipe made of metal is fit to an end portion of a tubular accordion member made of metal; a swage ring that is attached at a portion where the end portion of the pipe is fit to the end portion of the tubular accordion member, and constricts the end portion of the pipe and the end portion of the tubular accordion member from outside; a conductor ring that is arranged between the pipe and the tubular accordion member, has an inner circumferential face that faces the pipe and an outer circumferential face that faces the tubular accordion member, and has electrical conductivity; and a plurality of protrusion/recession portions formed on the inner circumferential face and the outer circumferential face.
