Abstract
A wire harness that includes an electric wire; a first tube that is made of a metal and covers an outer circumference of the electric wire; a braided wire that is formed by braiding conductive strands into a tubular shape, is attached to an outer circumferential surface of the first tube, and covers an outer circumference of a drawn-out portion of the electric wire, the drawn-out portion being drawn out from an end of the first tube; and a second tube that is made of a metal.
Claims9
A wire harness comprising:
- an electric wire;
- a first tube that is made of a metal and covers an outer circumference of the electric wire;
- a braided wire that is formed by braiding conductive strands into a tubular shape, is attached to an outer circumferential surface of the first tube, and covers an outer circumference of a drawn-out portion of the electric wire, the drawn-out portion being drawn out from an end of the first tube;
- and
- a second tube that is made of a metal and includes:
- a first end covering an outer circumference of the first tube with the braided wire being sandwiched between the first end and the outer circumferential surface of the first tube;
- and a second end located on a side opposite to the first end and covering the outer circumference of the drawn-out portion, and fixes the braided wire to the outer circumferential surface of the first tube, wherein:
- the electric wire includes a first electric wire and a second electric wire that is electrically connected to the first electric wire,
- the first electric wire has a single-core wire formed by a single conductor, and an insulating coating that covers an outer circumference of the single-core wire,
- the second electric wire has a stranded wire formed by twisting a plurality of metal strands, and an insulating coating that covers an outer circumference of the stranded wire,
- a connection where the first electric wire drawn out from the end of the first tube and the second electric wire located outside the first tube are electrically connected to each other is provided at a portion of the drawn-out portion in a longitudinal direction,
- the second tube covers an outer circumference of the connection, and
- the second tube has a protrusion that protrudes from an inner circumferential surface of the second tube toward the outer circumferential surface of the first tube and presses the braided wire against the outer circumferential surface of the first tube.
