[0013] Hereinafter, the wire harness assembly 1 according to an embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for ease of explanation and may be different from the actual ratios.

[0014] 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) such as a power source mounted on a vehicle and a device or between devices. The wire harness 3 is arranged in a predetermined shape inside an assembly member 5 integrally assembled therewith. The wire harness assembly 1 is assembled to a target member (not shown), such as a door trim of a vehicle.

[0015] As Figure 1 and Figure 2 shown, the wire harness assembly 1 includes a wire harness 3 and an assembly member 5.

[0016] As Figure 1 and Figure 2 shown, the wire harness 3 includes electric wires 7 and connectors 9.

[0017] The electric wire 7 includes, for example, a covered electric wire in which the outer periphery of a core wire made of a conductive material is covered with an insulating sheath, and a plurality of (four in the present embodiment) electric wires 7 are used. The electric wire 7 may be a flat cable in which the outer peripheries of a plurality of core wires are covered with an insulating sheath in a state where the plurality of core wires are arranged in parallel. The plurality of electric wires 7 are arranged such that the end portions on both sides thereof protrude from the assembly member 5. The plurality of electric wires 7 are arranged in such a manner that the end portions on one end side are gathered at one position and the end portions on the other end side branch.

[0018] 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 can be fitted to 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 end portions 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. A plurality of (five in the present embodiment) connectors 9 are used to correspond to the end portions of the plurality of electric wires 7 protruding from the assembly member 5.

[0019] As Figure 1 and 2 shown, the assembly member 5 includes a base material 11 and a covering member 13.

[0020] The base material 11 is made of a foam such as polyurethane or a non-woven fabric such as polypropylene fiber, polyethylene terephthalate fiber, or polyester fiber, and has sound insulation and heat insulation properties. The base material 11 is formed into a sheet shape, and its size is set such that the base material 11 is disposed within the range of the target component, and is assembled to the target component by a fixing method (not shown) such as press fitting. On one surface side of the base material 11, a plurality of (four in this embodiment) electric wires 7 of the wire harness 3 are arranged in a predetermined shape. The ends of the plurality of electric wires 7 protrude from the outer edge of the base material 11 by a predetermined length, each electric wire 7 is disposed on the base material 11, and the connector 9 is disposed outside the base material 11.

[0021] The covering member 13 is made of a film such as vinyl chloride or polyethylene, or a closed-cell foam or open-cell foam such as polyethylene, polypropylene, polystyrene, or an elastomer, and has sound insulation and heat insulation properties. The covering member 13 is formed into a sheet shape, and its size is set to be equal to the size of the base material 11 such that the covering member 13 is disposed within the range of the target component, and its thickness is set to be smaller than the thickness of the base material 11. A bonding portion 15 formed of an adhesive is provided on the surface of the covering member 13 facing the base material 11. The covering member 13 is attached to one surface side of the base material 11 through the bonding portion 15 with the plurality of electric wires 7 sandwiched between the covering member 13 and the base material 11. In a state where the covering member 13 is attached to the base material 11, the plurality of electric wires 7 arranged in a predetermined shape are held between the base material 11 and the covering member 13. Therefore, 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.

[0022] In a state where the wire harness assembly 1 is assembled to the target component, the connector 9 exposed from the assembled component 5 is fitted to the mating connector. At this time, since the electric wires 7 protrude from the outer edge of the assembled component 5 by a predetermined length, the connector 9 can move freely, so that it is easy to fit the connector 9 to the mating connector. By fitting the connector 9 to the mating connector, the electrical components are electrically connected to each other.

[0023] Here, in a conventional wire harness assembly, the bonding portion for attaching the base material and the covering member is provided on the entire surface of the assembled component. Therefore, a large amount of adhesive is used for the bonding portion, resulting in high cost.

[0024] On the other hand, in this embodiment, the bonding portion 15 includes an outer bonding portion 17 and an inner bonding portion 19. A non-bonding region 29 where the bonding portion 15 is not arranged is provided between the base material 11 and the covering member 13.

[0025] The outer bonding portion 17 is disposed between the base material 11 and the covering member 13 of the assembled component 5 along the outer edge of the assembled component 5. The outer bonding portion 17 joins the outer edge of the base material 11 and the outer edge of the covering member 13 to each other to integrally attach the base material 11 and the covering member 13. By providing the outer bonding portion 17 on the outer edge of the assembled component 5, the base material 11 and the covering member 13 can be integrated, and a non-bonding region 29 where the bonding portion 15 is not disposed can be formed inside the outer edge of the assembled component 5. Therefore, the amount of adhesive used can be reduced by the same amount as the non-bonding region 29 inside the outer edge of the assembled component 5.

[0026] The outer bonding portion 17 has a partition portion 21, and the bonding portion 17 is partitioned at the partition portion 21 to avoid the electric wire 7. In the present embodiment, four partition portions 21 are provided in the outer bonding portion 17. Since the electric wire 7 disposed in the partition portion 21 is not bonded to the outer bonding portion 17, the electric wire 7 can move freely in the partition portion 21. Therefore, the connector 9 provided at the end of the electric wire 7 can move freely, making it easy to mate the connector 9. In addition, by providing the partition portion 21 in the outer bonding portion 17, the partition portion 21 can be used as a guide for arranging the electric wire 7 and the assemblability can be improved. On the other hand, since the electric wire 7 disposed in the outer bonding portion 17 is bonded to the outer bonding portion 17, the movement of the electric wire 7 is restricted. Therefore, for example, when the movement of the connector 9 is restricted due to interference with peripheral components or the like, the connector 9 can be positioned by restricting the movement of the connector 9 provided at the end of the electric wire 7. In the present embodiment, four partition portions 21 are provided in the outer bonding portion 17, but the present invention is not limited thereto, and the number and position of the partition portions 21 can be set in consideration of restrictions on peripheral components and the like.

[0027] The inner bonding portion 19 is disposed between the base material 11 and the covering member 13 of the assembled component 5 inside the outer edge of the assembled component 5. The inner bonding portion 19 is disposed at a position avoiding the electric wire 7 of the wire harness 3. The portion other than the inner bonding portion 19 between the base material 11 and the covering member 13 is a non-bonding region 29 where the bonding portion 15 is not disposed. The inner bonding portion 19 joins the inner portion of the outer edge of the base material 11 and the inner portion of the outer edge of the covering member 13 to integrally attach the base material 11 and the covering member 13. By disposing the inner bonding portion 19 at a position inside the outer edge of the assembled component 5 that avoids the electric wire 7, the base material 11 and the covering member 13 can be stably integrated while suppressing the reduction of the non-bonding region 29 and minimizing the amount of adhesive used. In addition, by disposing the inner bonding portion 19 at a position avoiding the electric wire 7, the inner bonding portion 19 can be used as a guide for arranging the electric wire 7 and the assemblability can be improved.

[0028] will refer to Figures 3 to 6An example of a method for forming the bonding portion 15 is described. In the following description, it is assumed that the bonding portion 15 is formed on the base material 11, but the bonding portion 15 may also be formed on the covering member 13. First, as Figure 3 shown, a masking sheet 25 is disposed on one surface side of the base material 11. In the masking sheet 25, through holes 23 are formed at positions where the outer bonding portion 17 and the inner bonding portion 19 to be provided as the bonding portion 15 are to be provided. Next, as Figure 4 shown, an adhesive 27 is sprayed onto the masking sheet 25. As Figure 5 shown, the adhesive 27 is coated in the through holes 23 of the masking sheet 25 onto which the adhesive 27 is sprayed. Then, as Figure 6 shown, by removing the masking sheet 25 from the base material 11, the outer bonding portion 17 and the inner bonding portion 19 as the bonding portion 15, and the non-bonding region 29 are formed on the base material 11.

[0029] 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 a wire 7 and a connector 9 electrically connected to an end of the wire 7, and the wire harness 3 is disposed in the assembly member 5. The assembly member 5 includes a base material 11 and a covering member 13 attached to the base material 11 through a bonding portion 15. The bonding portion 15 includes an outer bonding portion 17 disposed along the outer edge of the assembly member 5. A non-bonding region 29 where the bonding portion 15 is not disposed is provided between the base material 11 and the covering member 13.

[0030] By providing the outer bonding portion 17 in the bonding portion 15, the base material 11 and the covering member 13 can be made integral, and a non-bonding region 29 where the bonding portion 15 is not disposed can be formed inside the outer edge of the assembly member 5. Therefore, the amount of adhesive used can be reduced by the same amount as the non-bonding region 29 inside the outer edge of the assembly member 5.

[0031] As a result, the cost of the wire harness assembly 1 can be reduced.

[0032] The bonding portion 15 includes an inner bonding portion 19 disposed at a position inside the outer edge of the assembly member 5 and avoiding the wire 7.

[0033] By providing the inner bonding portion 19 in the bonding portion 15, the base material 11 and the covering member 13 can be stably made integral while suppressing the reduction of the non-bonding region 29 and minimizing the amount of adhesive used. In addition, the inner bonding portion 19 can be used as a guide for disposing the wire 7, and the assemblability can be improved.

[0034] The outer bonding portion 17 has a partition portion 21, and the outer bonding portion 17 is partitioned at the partition portion 21 to avoid the wire 7.

[0035] Since the electric wire 7 disposed in the partition portion 21 is not attached to the outer attachment portion 17, the electric wire 7 can move freely in the partition portion 21. Accordingly, the connector 9 provided at the end portion of the electric wire 7 can move freely, making it easy to mate the connector 9. Further, the partition portion 21 can serve as a guide for disposing the electric wire 7 and can improve assemblability.

[0036] In the above-described embodiment, the number of electric wires 7 in the wire harness 3 is four, but the present invention is not limited thereto, and the number of electric wires 7 may be three or less or five or more. In the above-described embodiment, one end sides of the plurality of electric wires 7 are gathered into one connector 9, but the present invention is not limited thereto, and the connector 9 may be provided on each end side of the plurality of electric wires 7.
