Electric wire and wire harness
An electric wire includes a flat stranded conductor having a flat shape in cross sectional view and configured by a plurality of conductive wires each having a wire diameter of 1.2 mm or less and which are stranded to each other, and a flat covering portion that is an insulator and covers the flat stranded conductor. The flat covering portion has a uniform elongation of 43.5% or more.
1. An electric wire comprising:
a flat stranded conductor having a flat shape in cross sectional view and configured by a plurality of conductive wires each having a wire diameter of 1.2 mm or less and which are stranded to each other; and
a flat covering portion that is an insulator and covers the flat stranded conductor, wherein:
the flat covering portion is formed by a pressing or rolling process, and
the flat covering portion has a uniform elongation of 43.5% or more such that cracking of the flat covering portion during the pressing or rolling process is prevented.
2. The electric wire according to claim 1 , further comprising:
a round stranded conductor having a round shape in cross sectional view and configured by a plurality of conductive wires each having a wire diameter of 1.2 mm or less and which are stranded to each other; and
a round covering portion that is an insulator and covers the round stranded conductor, wherein
the plurality of conductive wires of the round stranded conductor are formed continuously by the same wires as the plurality of conductive wires of the flat stranded conductor,
the round covering portion is formed continuously with the flat covering portion, and
a thickness of the flat covering portion is set to 36.4% or more of a thickness of the round covering portion.
3. A wire harness comprising:
the electric wire according to claim 1 .
