Wire harness and method for producing exterior member of wire harness
A wire harness includes at least one conductive path, and an exterior member having a tubular shape and made of resin, the exterior member covering the conductive path. The exterior member includes a flexible tube portion with flexibility and a non-flexible tube portion with low flexibility lower than the flexibility of the flexible tube portion. At least one of the flexible tube portion and the non-flexible tube portion includes a thick portion and a thin portion which are arranged in a tube axis direction, the thick portion and the thin portion being different in thickness.
1. A wire harness comprising:
at least one conductive path;
an exterior member having a tubular shape and made of resin, the exterior member covering the conductive path, and the exterior member having an outer surface; and
a clamp including a tube attachment portion and a fixation portion, the tube attachment portion engages the outer surface of the exterior member, and the fixation portion is cantilevered to the tube attachment portion,
wherein the exterior member includes a flexible tube portion with corrugations having flexibility and a non-flexible tube portion without corrugations having low flexibility lower than the flexibility of the flexible tube portion; and
wherein the flexible tube portion includes a flexible thick portion defining a first wall thickness and a flexible thin portion defining a second wall thickness thinner than the first wall thickness,
the non-flexible tube portion includes a non-flexible thick portion defining a third wall thickness and a non-flexible thin portion defining a fourth wall thickness thinner than the third wall thickness, the non-flexible thick portion and the non-flexible thin portion are arranged in a tube axis direction,
the flexible tube portion is disposed on a terminal side of the exterior member with respect to the non-flexible tube portion,
the non-flexible tube portion includes a pair of convex members that protrude from the exterior surface of the exterior member, and the clamp is located between the convex members,
the non-flexible thick portion includes a first non-flexible thick portion and a second non-flexible thick portion, and the non-flexible thin portion is between the first non-flexible thick portion and the second non-flexible thick portion in the tube axis direction, and
the clamp is spaced away from at least one of the non-flexible thick portion and the non-flexible thin portion.
2. The wire harness according to claim 1 , wherein the exterior member is formed by integral molding of the flexible tube portion and the non-flexible tube portion.
3. The wire harness according to claim 1 , wherein the exterior member is formed by integration of the flexible tube portion and the non-flexible tube portion that have been formed to be divided.
4. The wire harness according to claim 1 , wherein the non-flexible thin portion is disposed in a part of the non-flexible tube portion to which the flexible tube portion is connected.
5. The wire harness according to claim 1 , wherein the non-flexible thick portion is disposed in a part of the non-flexible tube portion to which the flexible tube portion is connected.
6. The wire harness according to claim 1 , wherein the flexible thick portion and the flexible thin portion are formed with unchanging outer diameters.
7. The wire harness according to claim 1 , wherein the non-flexible thick portion and the non-flexible thin portion are formed with unchanging outer diameters at locations that are separate from the pair of convex members of the non-flexible tube portion.
8. The wire harness according to claim 1 , wherein the non-flexible thick portion is formed with straight walls.
9. The wire harness according to claim 1 , wherein the flexible tube portion includes a first flexible tube portion and a second flexible tube portion, and the non-flexible tube portion is between the first flexible tube portion and the second flexible tube portion in the tube axis direction.
