Mode for Carrying Out the Invention

[0009] Hereinafter, the wire harness assembly according to the present embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for convenience of explanation and may be different from the actual ratios.

[0010] As shown in FIG. 1, the wire harness assembly 1 according to the present embodiment is applied to a wire harness 3 that electrically connects between electrical components (not shown), such as between a power source and a device mounted on a vehicle, or between devices. The wire harness 3 is disposed in a predetermined shape inside an assembly member 5 that is integrally assembled. The wire harness assembly 1 is assembled to a target member (not shown), such as a door trim of a vehicle.

[0011] As shown in FIGS. 1 to 4, the wire harness assembly 1 includes a wire harness 3 and an assembling member 5.

[0012] As shown in FIGS. 1 to 4, the wire harness 3 includes electric wires 7 and connectors 9.

[0013] The electric wire 7 is, for example, a coated electric wire in which the outer periphery of a core wire made of a conductive material is coated with an insulating coating, and a plurality (here, three) are used. Note that the electric wire 7 may be a flat cable in which a plurality of core wires are arranged in parallel and the outer periphery is coated with an insulating coating. The plurality of electric wires 7 are arranged such that one end side is gathered at one location with respect to the assembling member 5 and the other end sides are branched respectively.

[0014] The connector 9 includes, 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 is, for example, capable of fitting with a mating housing (not shown) of a mating connector (not shown) electrically connected to an electrical component mounted on a vehicle. The terminals are electrically connected to the terminal portions of the electric wires 7 and are housed in the housing. The terminals are electrically connected to mating terminals (not shown) housed in the mating housing when the housing and the mating housing are fitted together. The connectors 9 are used in a plurality (here, four) corresponding to the terminal portions of the plurality of electric wires 7.

[0015] As shown in FIGS. 1 to 4, the assembling member 5 includes a base material 11 and a cover material 13.

[0016] The base material 11 is made of, for example, a foam such as urethane, a non-woven fabric such as polypropylene fiber, polyethylene terephthalate fiber, or polyester-based fiber, and has sound insulation and heat insulation properties. The base material 11 is formed in a sheet shape with a size set so as to be disposed within the range of the target member, and is assembled to the target member by fixing means (not shown) such as press-fitting. The base material 11 includes a base main body portion 15 and a base extension portion 17. The base main body portion 15 is formed, for example, in a rectangular shape. A plurality (here, three) of 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 arranged corresponding to each of a plurality (here, four) of connectors 9 of the wire harness 3 with respect to the base main body portion 15, and is a member continuous with the base main body portion 15 and extends outward from the outer edge of the base main body portion 15. On one surface side of the base extension portion 17, a terminal portion of the electric wire 7 and the connector 9 are arranged.

[0017] The cover material 13 is made of, for example, a film such as vinyl chloride or polyethylene, an independent foam or continuous foam such as polyethylene, polypropylene, polystyrene, or elastomer, and has sound insulation and heat insulation properties. The cover material 13 is formed in a sheet shape with a size set to be equivalent to that of the base material 11 so as to be disposed within the range of the target member, and with a thickness set to be thinner than that of the base material 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 (here, a rectangular shape) as the base main body portion 15. An adhesive is applied to the surface of the cover main body portion 19 that faces the base main body portion 15, and it is attached to one surface side of the base main body portion 15 so as to sandwich the base main body portion 15 and the plurality of electric wires 7. 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 disposed in the assembling member 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 inside the base material 11 and the cover material 13. Therefore, the main body portion 27 of the assembling member 5 can protect the electric wires 7 of the wire harness 3 and can maintain the arrangement shape of the electric wires 7.

[0018] The cover extension part 21 is arranged corresponding to each of the plurality (here, four) of base extension parts 17 with respect to the cover main body part 19, and is a member continuous with the cover main body part 19. It extends outward from the outer edge of the cover main body part 19 in the same shape as the base extension part 17. An adhesive is applied to the surface of the cover extension part 21 facing the base extension part 17, and it is attached to one side surface of the base extension part 17 so as to sandwich the base extension part 17, the terminal part of the electric wire 7, and the connector 9. The base extension part 17 and the cover extension part 21 constitute an extension part 29 in the assembling member 5 in which the terminal part of the electric wire 7 of the wire harness 3 and the connector 9 are arranged inside. The extension part 29 is provided in plurality (here, five) corresponding to all (here, five) of the connectors 9 in the assembling member 5. In a state where the cover extension part 21 is attached to the base extension part 17, the terminal part of the electric wire 7 and the connector 9 are held inside the base material 11 and the cover material 13. Therefore, the terminal part of the electric wire 7 of the wire harness 3 and the connector 9 can be protected by the extension part 29 of the assembling member 5. By protecting the connector 9 with the extension part 29, direct interference between the connector 9 and the peripheral members can be prevented when the wire harness assembly 1 is packed or assembled to the target member. For this reason, damage to the connector 9 and the peripheral members can be suppressed. In addition, since the extension part 29 is provided corresponding to all of the connectors 9, all of the connectors 9 of the wire harness 3 can be protected.

[0019] In addition, for example, when the wire harness assembly 1 is packed, if the extension part 29 protrudes from the packing box, the extension part 29 may be folded back toward the main body part 27. Even in such a state, the connector 9 is not exposed to the outside, and direct interference between the connector 9 and the peripheral members can be prevented.

[0020] As shown in FIGS. 3 and 4, the cover material 13 is provided with a dividing portion 23. The dividing portion 23 is formed, for example, by making a cut (notch) in the cover material 13. The dividing portion 23 is arranged at a position where the terminal portion of the electric wire 7 is exposed with a predetermined length when the cover extension portion 21 is peeled off from the base extension portion 17. The dividing portion 23 can divide the cover main body portion 19 and the cover extension portion 21 and peel off only the cover extension portion 21 from the base extension portion 17 when peeling the cover extension portion 21 from the base extension portion 17. For example, when assembling the wire harness assembly 1 to the target member, 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 hold or cut the cover material 13 at a predetermined position with a jig or the like, and the assemblability can be improved. In addition, by arranging the dividing portion 23 at a position where the terminal portion of the electric wire 7 is exposed with a predetermined length, the connector 9 can be easily fitted to the mating connector, and the assemblability can be improved. Here, the dividing portion 23 is arranged so as to divide the cover main body portion 19 and the cover extension portion 21, but the present invention is not limited to this. For example, when the extension length of the extension portion 29 from the main body portion 27 is long, the dividing portion 23 may be arranged at a position where only the cover extension portion 21 covering the terminal portion of the electric wire 7 and the connector 9 is divided when peeling the cover extension portion 21 from the base extension portion 17.

[0021] As shown in FIGS. 3 and 4, the cover material 13 is provided with a gripping portion 25. The gripping portion 25 is a member continuous with the cover extension portion 21 and protrudes outward from the outer edge of the cover extension portion 21. The gripping portion 25 is arranged so as to protrude 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. No adhesive is applied to the gripping portion 25. The gripping portion 25 serves as a portion to be gripped by an operator or the like when peeling the cover extension portion 21 from the base extension portion 17. By providing the gripping portion 25 on the cover extension portion 21, it is possible to easily peel the cover extension portion 21 from the base extension portion 17, and the assemblability can be improved.

[0022] In such a wire harness assembly 1, there is provided a wire harness 3 having an electric wire 7 and a connector 9 electrically connected to the terminal portion of the electric wire 7, and an assembly member 5 in which the wire harness 3 is disposed inside. The assembly member 5 has a main body portion 27 in which the electric wire 7 is disposed inside, and an extension portion 29 formed of a member continuous with the main body portion 27 and in which the connector 9 is disposed inside.

[0023] Since the connector 9 is disposed inside the extension portion 29 of the assembly member 5, the connector 9 can be protected. Therefore, direct interference between the connector 9 and peripheral members can be prevented during packaging of the wire harness assembly 1 or during assembly to a target member, and damage to the connector 9 and peripheral members can be suppressed.

[0024] Therefore, in such a wire harness assembly 1, interference between the connector 9 and peripheral members can be prevented.

[0025] Also, a plurality of connectors 9 are provided. The extension portion 29 is provided corresponding to all the connectors 9.

[0026] Therefore, all the connectors 9 of the wire harness 3 can be protected.

[0027] The assembly member 5 also has a base material 11 and a cover material 13 attached to the base material 11.

[0028] Therefore, in the extension portion 29 of the assembly member 5, the connector 9 can be easily exposed by peeling the cover material 13 from the base material 11, and the assemblability can be improved.

[0029] Also, the cover material 13 is provided with a dividing portion 23 that can divide the cover material 13 so as to expose the connector 9 when the cover material 13 is peeled from the base material 11.

[0030] Therefore, when exposing the connector 9, there is no need to hold or cut the cover material 13 at a predetermined position with a jig or the like, and the assemblability can be improved.

[0031] In addition, the cover material 13 is provided with a gripping portion 25 that projects from the outer edge of the base material 11.

[0032] Therefore, when peeling the cover material 13 from the base material 11, by gripping the gripping portion 25, it is possible to easily peel the cover material 13 from the base material 11, and the assemblability can be improved.

[0033] As described above, the present embodiment has been described, but the present embodiment is not limited to these, and various modifications are possible within the scope of the gist of the present embodiment.

[0034] For example, the wires of the wire harness are three, but not limited to this, the number of wires may be two or less, or four or more. In addition, one end side of a plurality of wires is aggregated into one connector, but not limited to this, a connector may be provided for each of one end sides of a plurality of wires.
