摘要:
A wire harness has an exterior component (11a) that covers a certain part of at least one wires (12). The exterior component (11a) has parts having different hardness, including a relatively hard first part (111a), a relatively soft second part (112a), and a third part (113a) having an intermediate hardness between that of the first parts (111a, 112a). The first part is formed on a surface of the exterior component and functions as a shape keeping member and a protector. The second and third parts (112a, 113a) surround the certain part of the at least one wire 12 and each functions as a cushioning material and a muffler/soundproofing material. The first part (111a), the second part (112a), and the third part (113a) are formed integrally from a non-woven fabric (2) with thermo plasticity.

A wire harness manufacturing method includes a first step of covering a periphery of the wire with a molded body (13) having a thermoplastic material, and heating the molded body (13) to a temperature at which plastic deformation by thermo plasticity is possible and pressuring the molded body (13) to have predetermined cross-sectional shape and size. The method also includes a second step of, after the first step, while the molded body (13) has the temperature at which plastic deformation by thermo plasticity is possible, molding the thermoplastic material to have a predetermined axial shape, and cooling the molded body (13) having the predetermined axial shape.

An electric wire protection structure has a structure in which a branch portion of an electric wire bundle is protected. In the electric wire protection structure, a protection portion covers the branch portion of the electric wire bundle, the protection portion being formed by heating and compressing a thermoplastic material in a state of covering at least the branch portion of the electric wire bundle.
摘要:
A wire harness includes a bundle of electric wires and a protector protecting the bundle of electric wires by extending in a longitudinal direction of the bundle of electric wires and surrounding a portion thereof. The protector includes a base material and a binder material having a lower melting point than the base material, the protector being joined in a joint portion thereof by cooling and solidifying the melted binder material. In a case where a first side portion and a second side portion are each provided as a portion along the longitudinal direction in an outer peripheral surface of the protector and the second side portion is disposed opposite the first side portion with the bundle of electric wires therebetween, a portion of the binder material in each of the first side portion and the second side portion is melted, cooled, and solidified such that the second side portion is harder than the first side portion.
摘要:
A sheet-like member (14) is wound around an outer circumferential surface of a predetermined portion of a wire bundle (12) of a wire harness (1), and both side parts (141, 142) of the sheet-like member (14) are superposed on an outer circumferential surface of a predetermined portion of the wire bundle (12). A jig (5) is disposed between the outer circumferential surface of the predetermined portion of the wire bundle (12) and an inner circumferential surface of the superposed side parts (141, 142) of the sheet-like member (14). A pressurizing member (6) of an ultrasonic welder pressurizes at least part of the superposed portion of the sheet-like member (14) for ultrasonic welding, thereby forming a protector (13) from the sheet-like member (14) on the outer circumferential surface of the predetermined portion of the wire bundle (12).

A method for manufacturing a wire harness includes holding a predetermined part of electric wires (91) with first and second molded bodies (931, 932). The first and second molded bodies (931, 932) are placed on a lower holding tool (11a) and are pressurized with lower and upper molds (21a, 22a) having a heater to heat the first and second molded bodies (931, 932) while pressurize them to cover the periphery of the predetermined part of the electric wires (91) with the first and second molded bodies (931, 932). Contact surfaces of the first and second molded bodies (931, 932) are welded. Thereafter, the predetermined part of the electric wires (91) covered with the first and second molded bodies (931, 932) in the state where it is placed on the upper side of the first lower holding tool (11a), is removed from the upper and lower molds (22a, 21a).
摘要:
A predetermined part of electric wires (91) is held or wrapped in a first material (801) and a second material (802) formed of a thermoplastic material, and a protective layer material (803) formed of a water repellent material is provided on approximately the entire surface of the first material and the second material. The first material (801), the second material (802) and the protective layer material (803) are heated and pressurized. The first material (801) and the second material (802) are molded to have a predetermined shape and size. The protective layer material (803) is joined to the surface of the first material and the second material (802) by melting at least a part of the surface layer of the first material (801) and the second material (802). Further, a material having high abrasion resistance is selected as the protective layer material (803).

A method of manufacturing a wire harness is provided. A portion of a wire is mounted on a first holder such that the portion of the wire is disposed between a thermoplastic material and another thermoplastic material, the thermoplastic material and the other thermoplastic material, that are mounted on the first holder, are pressed by heater-equipped the lower mold and the upper mold, thereby press-forming and heating the thermoplastic material and the other thermoplastic material, so that the portion of the wire is covered around with the thermoplastic material and the other thermoplastic material and that mutually contacting surfaces of the thermoplastic material and the other thermoplastic material are welded, and thereafter, the portion of the wire that is covered the thermoplastic material and the other thermoplastic material is removed from the lower mold and the upper mold while being mounted on an upper side of the first holder.
