[0011] Hereinafter, the wire harness assembly 1 according to an embodiment will be described in detail with reference to the accompanying drawings. Note that the dimensional ratios in the figures are exaggerated for ease of explanation and may be different from the actual ratios.

[0012] As Figure 1 shown, the wire harness assembly 1 according to the present embodiment is applied to, for example, a wire harness 3 that electrically connects electrical components (not shown) to a device or electrically connects devices to each other. The electrical components are, for example, power sources mounted on a vehicle. The wire harness 3 is arranged in a predetermined shape inside an assembly member 5 that is integrally assembled therewith. The wire harness assembly 1 is assembled to a target member (not shown), such as a door trim of a vehicle.

[0013] As Figures 1 to 4 shown, the wire harness assembly 1 includes a wire harness 3 and an assembly member 5.

[0014] As Figures 1 to 4 shown, the wire harness 3 includes electric wires 7 and connectors 9.

[0015] The electric wires 7 include, for example, covered electric wires in which the outer periphery of a core wire made of a conductive material is covered with an insulating sheath, and multiple (three in the present embodiment) electric wires 7 are used. The electric wires 7 may be flat cables in which the outer peripheries of multiple core wires are covered with an insulating sheath in a state where the multiple core wires are arranged in parallel. The multiple electric wires 7 are arranged with respect to the assembly member 5 such that one end side thereof converges at one position and the other end side branches.

[0016] The connectors 9 include, for example, a housing (not shown) made of an insulating material such as synthetic resin and terminals (not shown) made of a conductive material. The housing can be fitted to a mating housing (not shown) of a mating connector (not shown) that is electrically connected to an electrical component mounted on a vehicle. The terminals are electrically connected to the ends of the electric wires 7 and are accommodated in the housing. By fitting the housing to the mating housing, the terminals are electrically connected to mating terminals (not shown) accommodated in the mating housing. Multiple (four in the present embodiment) connectors 9 are used to correspond to the ends of the multiple electric wires 7.

[0017] As Figures 1 to 4 shown, the assembly member 5 includes a base portion 11 and a cover portion 13.

[0018] The base portion 11 is made of a foam such as polyurethane or a non-woven fabric of polypropylene fibers, polyethylene terephthalate fibers, polyester-based fibers, etc., and has sound insulation and heat insulation properties. The base portion 11 is formed in a sheet shape, and its size is set such that the base portion 11 is disposed within the range of the target component, and is assembled to the target component by a fixing method such as press-fitting (not shown). The base portion 11 includes a base main body portion 15 and a base extension portion 17. The base main body portion 15 is formed in a rectangular shape, for example. A plurality of (three in this embodiment) electric wires 7 of the wire harness 3 are arranged in a predetermined shape on one surface side of the base main body portion 15. The base extension portion 17 is disposed relative to the base main body portion 15 to correspond to each of a plurality of (four in this embodiment) connectors 9 of the wire harness 3. The base extension portion 17 extends outward from the outer edge of the base main body portion 15 as a single component continuous with the base main body portion 15. The end portions of the electric wires 7 and the connectors 9 are disposed on one surface side of the base extension portion 17.

[0019] The cover portion 13 is made of a film such as vinyl chloride or polyethylene, or a closed-cell foam or open-cell foam of polyethylene, polypropylene, polystyrene, elastomer, etc., and has sound insulation and heat insulation properties. The cover portion 13 is formed in a sheet shape, and its size is set to be equal to the size of the base portion 11 such that the cover portion 13 is disposed within the range of the target component, and its thickness is set to be smaller than the thickness of the base portion 11, and includes a cover main body portion 19 and a cover extension portion 21. The cover main body portion 19 is formed in the same shape as the base main body portion 15 (rectangular shape in this embodiment). An adhesive is coated on the surface of the cover main body portion 19 facing the base main body portion 15, and the cover main body portion 19 is attached to one surface side of the base main body portion 15 in such a manner that a plurality of electric wires 7 are sandwiched between the cover main body portion 19 and the base main body portion 15. The base main body portion 15 and the cover main body portion 19 constitute a main body portion 27, in which the electric wires 7 of the wire harness 3 are arranged in the assembled component 5. In a state where the cover main body portion 19 is attached to the base main body portion 15, a plurality of electric wires 7 arranged in a predetermined shape are held between the base portion 11 and the cover portion 13. Therefore, the main body portion 27 of the assembled component 5 can protect the electric wires 7 of the wire harness 3 and maintain the arranged shape of the electric wires 7.

[0020] The cover extension portion 21 is arranged relative to the cover main body portion 19 to correspond to each of a plurality (four in this embodiment) of base extension portions 17. The cover extension portion 21, as a single component continuous with the cover main body portion 19, extends outward from the outer edge of the cover main body portion 19 in the same shape as the base extension portion 17. An adhesive is coated on the surface of the cover extension portion 21 facing the base extension portion 17, and the cover extension portion 21 is attached to one surface side of the base extension member 17 in such a manner that the end of the wire 7 and the connector 9 are sandwiched between the cover extension portion 21 and the base extension portion 17. The base extension portion 17 and the cover extension portion 21 constitute the extension portion 29, in which the end of the wire 7 of the wire harness 3 and the connector 9 are arranged in the assembled component 5. In the assembled component 5, a plurality (four in this embodiment) of extension portions 29 are provided to correspond to all (four in this embodiment) of the connectors 9. In the state where the cover extension portion 21 is attached to the base extension portion 17, the end of the wire 7 and the connector 9 are held between the base 11 and the cover portion 13. Therefore, the end of the wire 7 of the wire harness 3 and the connector 9 can be protected by the extension portion 29 of the assembled component 5. By protecting the connector 9 with the extension portion 29, direct interference between the connector 9 and the peripheral components can be prevented when the wire harness assembly 1 is packaged or assembled to the target component. Therefore, damage to the connector 9 and the peripheral components can be suppressed. In addition, since the extension portion 29 is provided to correspond to all of the connectors 9, all of the connectors 9 of the wire harness 3 can be protected.

[0021] For example, when the wire harness assembly 1 is packaged, if the extension portion 29 protrudes from the packaging box, the extension portion 29 can be folded back toward the main body portion 27. Even in this state, the connector 9 is not exposed to the outside, and direct interference between the connector 9 and the peripheral components can be prevented.

[0022] As Figure 3 and Figure 4As shown, the cover portion 13 includes a dividing portion 23. The dividing portion 23 is formed, for example, by making a cut (notch) in the cover portion 13. The dividing portion 23 is disposed at a position where the end portion of the electric wire 7 is exposed by a predetermined length when the cover extension portion 21 is peeled off from the base extension portion 17. When the cover extension portion 21 is peeled off from the base extension portion 17, the dividing portion 23 divides the cover main body portion 19 and the cover extension portion 21, so that only the cover extension portion 21 can be peeled off from the base extension portion 17. For example, when the wire harness assembly 1 is assembled to a target component, the connector 9 can be exposed by peeling off the cover extension portion 21 divided by the dividing portion 23 from the base extension portion 17. Therefore, when exposing the connector 9, it is not necessary to press or cut the cover portion 13 at a predetermined position with a jig or the like, and the assemblability can be improved. In addition, by disposing the dividing portion 23 at a position where the end portion of the electric wire 7 is exposed by a predetermined length, the connector 9 can be easily mated with a mating connector, and the assemblability can be improved. In the present embodiment, the dividing portion 23 is arranged to divide the cover extension portion 21 from the cover main body portion 19, but the present invention is not limited thereto. For example, when the length of the extension portion 29 extending from the main body portion 27 is long, the dividing portion 23 may be disposed at a position where only the cover extension portion 21 covering the end portion of the electric wire 7 and the connector 9 is divided when the cover extension portion 21 is peeled off from the base extension portion 17.

[0023] As Figure 3 and Figure 4 shown, the cover portion 13 includes a gripping portion 25. The gripping portion 25 projects outward from the outer edge of the cover extension portion 21 as a single member continuous with the cover extension portion 21. The gripping portion 25 is arranged to project from the outer edge of the base extension portion 17 in a state where the cover extension portion 21 is attached to the base extension portion 17. The gripping portion 25 is not coated with an adhesive. The gripping portion 25 is a portion that is gripped by an operator, for example, when peeling off the cover extension portion 21 from the base extension portion 17. By providing the gripping portion 25 in the cover extension portion 21, the cover extension portion 21 can be easily peeled off from the base extension portion 17, and the assemblability can be improved.

[0024] The wire harness assembly 1 according to the present embodiment includes a wire harness 3 and an assembly member 5. The wire harness 3 includes an electric wire 7 and a connector 9 electrically connected to the end portion of the electric wire 7, and the wire harness 3 is disposed in the assembly member 5. The assembly member 5 includes a main body portion 27 and an extension portion 29. The electric wire 7 is disposed in the main body portion 27, and the connector 9 is disposed in the extension portion 29. The extension portion 29 is formed as a single member continuous with the main body portion 27.

[0025] Since the connector 9 is disposed inside the extension portion 29 of the assembly member 5, the connector 9 can be protected. Therefore, when the wire harness assembly 1 is packaged or assembled to a target component, direct interference between the connector 9 and peripheral components can be prevented, and damage to the connector 9 and peripheral components can be suppressed.

[0026] Therefore, in the wiring harness assembly 1, interference between the connector 9 and the peripheral components can be prevented.

[0027] A plurality of connectors 9 are provided. The extension portion 29 is provided corresponding to each connector 9.

[0028] Therefore, all the connectors 9 of the wiring harness 3 can be protected.

[0029] The assembly component 5 includes a base portion 11 and a cover portion 13 attached to the base portion 11.

[0030] Therefore, in the extension portion 29 of the assembly component 5, by peeling the cover portion 13 from the base portion 11, the connector 9 can be easily exposed, and the assemblability can be improved.

[0031] The cover portion 13 includes a dividing portion 23. When the cover portion 13 is peeled from the base portion 11, the dividing portion 23 can divide the cover portion 13 to expose the connector 9.

[0032] Therefore, when exposing the connector 9, it is not necessary to press or cut the cover portion 13 at a predetermined position with a jig or the like, and the assemblability can be improved.

[0033] The cover portion 13 includes a gripping portion 25 protruding from the outer edge of the base portion 11.

[0034] Therefore, when the cover portion 13 is peeled from the base portion 11, the cover portion 13 can be easily peeled from the base portion 11 by the gripping portion 25, and the assemblability can be improved.

[0035] In the above embodiment, the number of wires 7 in the wiring harness 3 is three, but the present invention is not limited thereto. The number of wires 7 can be two or less, or four or more. In the above embodiment, one end sides of a plurality of wires 7 are gathered into one connector 9, but the present invention is not limited thereto, and the connectors 9 can be provided on each end side of the plurality of wires 7.
