Wire harness
A wire harness including a round electric wire and a flat electric wire. The round electric wire includes a round conductor made of a predetermined metal and having a round cross-sectional shape and a first coating portion. The flat electric wire includes a flat conductor having a flat cross-sectional shape and a second coating portion. The round electric wire and the flat electric wire are arranged in parallel. The round conductor has a diameter equal to or less than a predetermined reference value. The flat conductor has a thickness equal to or less than the reference value and a width in which ensure cross-sectional area of the flat conductor more than area of a circle having a diameter equal to the reference value.
1. A wire harness comprising:
a first round electric wire; and
a flat electric wire,
wherein the first round electric wire includes a round conductor made of a predetermined metal and having a round cross-sectional shape and a first coating portion,
wherein the flat electric wire includes a first flat conductor having a flat cross-sectional shape and a second coating portion,
wherein the first round electric wire and the flat electric wire are arranged in parallel,
wherein the round conductor has a diameter equal to or less than a predetermined reference value, and
wherein the first flat conductor has a thickness equal to or less than the reference value and a width which ensures the flat cross-sectional area of the first flat conductor is greater than an area of a circle having a diameter equal to the reference value.
2. The wire harness according to claim 1 ,
wherein the thickness of the first flat conductor is smaller than the diameter of the round conductor.
3. The wire harness according to claim 1 ,
wherein the reference value is a value determined to be equal to or less than a bending endurance limit value, and
wherein the bending endurance limit value is a minimum value of a thickness in a surface folding direction of a predetermined metal that satisfies a predetermined disconnection condition when a bending of a predetermined curvature is repeatedly applied a predetermined number of times in the surface folding direction.
4. The wire harness according to claim 1 ,
wherein the first round electric wire is spaced apart from the flat electric wire.
5. The wire harness according to claim 1 , further comprising
a second flat conductor having a flat cross-sectional shape.
6. The wire harness according to claim 1 , further comprising:
a second round electric wire.
7. The wire harness according to claim 6 ,
wherein the first round electric wire and the second round electric wire are both spaced apart from the flat electric wire.
8. The wire harness according to claim 7 ,
wherein the flat electric wire is accommodated along a long axis direction of an oblong cross section of the wire harness and the first round electric wire and the second round electric wire are stacked in a surface folding direction with the flat electric wire.
