Wire harness and manufacturing method of wire harness
View Patent ↗A wire harness including one or more electrically conductive paths and a resin molded product having a tubular shape which accommodates and protects the one or more electrically conductive paths. The resin molded product includes a first part having clearances along a circumferential direction between an inner surface of the resin molded product and outer surfaces of the one or more electrically conductive paths and a second part having substantially no clearance between the inner surface of the resin molded product and an outer surface of one of the one or more electrically conductive paths in an area along the circumferential directions.
1. A wire harness comprising:
one or more electrically conductive paths; and
a resin molded product having a tubular shape which accommodates and protects the one or more electrically conductive paths, wherein
the resin molded product includes a first part having clearances along a circumferential direction in substantially whole circumference between an inner surface of the resin molded product and outer surfaces of the one or more electrically conductive paths and a second part having substantially no clearance between the inner surface of the resin molded product and an outer surface of one of the one or more electrically conductive paths in an area along the circumferential direction, and
each of the first part and the second part of the resin molded product includes an exposed outer surface.
2. The wire harness according to claim 1 , wherein the first part and the second part are alternatively arranged.
3. A manufacturing method of a wire harness including one or more electrically conductive paths and a resin molded product having a tubular shape which accommodates and protects the one or more electrically conductive paths, the manufacturing method comprising:
extruding straight an extruded resin material having an internal space to a die from a resin extruding machine and supplying straight the one or more electrically conductive paths toward the internal space together with the extrusion;
forming the extruded resin material as a first part and a second part such that the first part includes an inner surface that is spaced away from the one or more conductive paths and the second part has an inner surface that contacts the one or more conductive paths aligning an inner surface of the extruded resin material corresponding to outer surfaces of the one or more electrically conductive paths.
