Abstract
A wire harness includes electrical wires and an outer covering member. The outer covering member includes tube portions different in cross-sectional shape and size and a guiding shape portion between adjacent tube portions. The guiding shape portion guides the electrical wires when inserted. A cap is provided to each one end of the electrical wires, and the electrical wires are passed through the guiding shape portion with the caps facing frontward. A wire harness and a method for inserting electric conductive paths through the wire harness can enhance workability related to the electrical conductive paths and an outer covering member while suiting the wire harness to the shapes and the usage environments.
Claims6
A wire harness comprising:
- a plurality of electrical conductive paths;
- and an outer covering member configured to have the electrical conductive paths inserted therethrough and protect the electrical conductive paths, wherein the outer covering member includes, along an axial direction thereof, a pair of tube portions different from each other in cross-sectional shape and/or size and a guiding shape portion provided between the tube portions, the guiding shape portion serving as a portion that guides front ends of the electrical conductive paths from one of the tube portions to the other of the tube portions at a time the electrical conductive paths are inserted, and the guiding shape portion is formed so that a shape thereof gradually changes from one to the other of the tube portions and configured to guide each of the front ends of the electrical conductive paths individually, the guiding shape portion comprising a plurality of separate tube elements, each tube element receiving at least one of the conductive paths, the guiding shape portion including at least three of the tube elements, each of the tube elements being formed in a spiral shape.
A method for inserting electrical conductive paths through a wire harness, the method comprising:
- providing a cap to each one end of a plurality of electrical conductive paths of a wire harness, the wire harness including an outer covering member configured to have the electrical conductive paths inserted therethrough and protect the electrical conductive paths, the outer covering member including, along an axial direction thereof, a pair of tube portions different from each other in cross-sectional shape and/or size and a guiding shape portion provided between the tube portions, the guiding shape portion serving as a portion that guides front ends of the electrical conductive paths from one of the tube portions to the other of the tube portions at a time the electrical conductive paths are inserted, and the guiding shape portion is formed so that a shape thereof gradually changes from one to the other of the tube portions and configured to guide each of the front ends of the electrical conductive paths individually, the guiding shape portion comprising a plurality of separate tube elements, each tube element receiving at least one of the conductive paths, the guiding shape portion including at least three of the tube elements, each of the tube elements being formed in a spiral shape;
- and passing the electrical conductive paths through the guiding shape portion, and an associated tube element, with one side that has the caps facing frontward at the time the electrical conductive paths are inserted through the outer covering member.
