Modes for Carrying Out the Invention

[0009] Hereinafter, the wire harness assembly according to this embodiment will be described in detail with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for the 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 and 2, the wire harness assembly 1 includes a wire harness 3 and an assembly member 5.

[0012] As shown in FIGS. 1 and 2, the wire harness 3 includes electric wires 7 and connectors 9.

[0013] The electric wire 7 is, 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 coating, and a plurality (here, four) 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 covered with an insulating coating. The terminal portions on both sides of the plurality of electric wires 7 are respectively exposed from the assembly member 5. The terminal portions on one end side of the plurality of electric wires 7 are gathered and arranged at one location, and the terminal portions on the other end side are arranged so as to branch 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, five) corresponding to the terminal portions of the plurality of electric wires 7 exposed from the assembly member 5.

[0015] As shown in FIGS. 1 and 2, the assembly 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 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. On one side of the base material 11, a plurality (here, four) of electric wires 7 of the wire harness 3 are arranged in a predetermined shape. The terminal portions of the plurality of electric wires 7 arranged on the base material 11 are such that each electric wire 7 has a predetermined length and protrudes from the outer edge of the base material 11, and the connector 9 is disposed outside the base material 11.

[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. The cover material 13 is attached to one side of the base material 11 so as to sandwich the base material 11 and the plurality of electric wires 7 by an adhesive portion 15 made of an adhesive provided on the surface facing the base material 11. In a state where the cover material 13 is attached to the base material 11, the plurality of electric wires 7 arranged in a predetermined shape are held inside the base material 11 and the cover material 13. Therefore, the electric wires 7 of the wire harness 3 can be protected by the assembling member 5, and the arrangement shape of the electric wires 7 can be maintained.

[0018] The connector 9 exposed from the assembling member 5 is fitted to a mating connector in a state where the wire harness assembly 1 is assembled to the target member. At this time, since the electric wires 7 have a predetermined length and protrude from the outer edge of the assembling member 5, the connector 9 can be freely moved, facilitating the fitting of the connector 9 and the mating connector. By fitting the connector 9 and the mating connector, the electrical components are electrically connected.

[0019] Here, in the conventional wire harness assembly, the adhesive portion 15 for attaching the base material 11 and the cover material 13 was provided on the entire surface of the assembly member 5. For this reason, the amount of adhesive used for the adhesive portion 15 was large, resulting in high costs.

[0020] Therefore, the adhesive portion 15 includes an outer adhesive portion 17 and an inner adhesive portion 19. And, a non-adhesive region 29 where the adhesive portion 15 is not arranged is provided between the base material 11 and the cover material 13.

[0021] The outer adhesive portion 17 is arranged along the outer edge of the assembly member 5 between the base material 11 and the cover material 13 of the assembly member 5. The outer adhesive portion 17 adheres the outer edges of the base material 11 and the cover material 13 and attaches the base material 11 and the cover material 13 integrally. By providing the outer adhesive portion 17 at the outer edge of the assembly member 5, the base material 11 and the cover material 13 can be made integral, and the non-adhesive region 29 where the adhesive portion 15 is not arranged can be made inside the outer edge of the assembly member 5. For this reason, the amount of adhesive used for the non-adhesive region 29 inside the outer edge of the assembly member 5 can be reduced.

[0022] The outer adhesive portion 17 has a dividing portion 21 that is divided so as to avoid the wire 7. Here, four dividing portions 21 are provided in the outer adhesive portion 17. Since the wire 7 disposed in the dividing portion 21 is not adhered to the outer adhesive portion 17, it can move freely at the dividing portion 21. For this reason, the connector 9 provided at the terminal portion of the wire 7 can be moved freely, and it is possible to facilitate the fitting of the connector 9. In addition, since the outer adhesive portion 17 has the dividing portion 21, the dividing portion 21 can be used as a guide for arranging the wire 7, and the assemblability can be improved. On the other hand, the wire 7 disposed in the outer adhesive portion 17 is adhered to the outer adhesive portion 17, so its movement is restricted. For this reason, for example, when there is a restriction on the movement of the connector 9 due to interference with peripheral members or the like, the movement of the connector 9 provided at the terminal portion of the wire 7 can be restricted to position the connector 9. Here, although the dividing portion 21 of the outer adhesive portion 17 is four, it is not limited to this, and the dividing portion 21 may be set in consideration of restrictions with peripheral members and the like.

[0023] The inner adhesive portion 19 is disposed inside the outer edge of the assembling member 5 between the base material 11 and the cover material 13 of the assembling member 5. The inner adhesive portion 19 is disposed at a position avoiding the wire 7 of the wire harness 3. Between the base material 11 and the cover material 13, the portion other than the inner adhesive portion 19 becomes a non-adhesive region 29 where the adhesive portion 15 is not disposed. The inner adhesive portion 19 adheres the inside of the outer edges of the base material 11 and the cover material 13, and attaches the base material 11 and the cover material 13 integrally. By disposing the inner adhesive portion 19 at a position inside the outer edge of the assembling member 5 and avoiding the wire 7, it is possible to suppress a decrease in the non-adhesive region 29 and minimize the amount of adhesive used, while stably integrating the base material 11 and the cover material 13. In addition, by disposing the inner adhesive portion 19 at a position avoiding the wire 7, the inner adhesive portion 19 can be used as a guide for arranging the wire 7, and the assemblability can be improved.

[0024] Here, an example of the method for forming the bonding portion 15 will be described with reference to FIGS. 3 to 6. In the following description, the bonding portion 15 is described as being formed on the base material 11, but the bonding portion 15 may be formed on the cover material 13. First, as shown in FIG. 3, a masking sheet 25 having a through hole 23 formed at a position where an outer bonding portion 17 and an inner bonding portion 19 as the bonding portion 15 are provided is disposed on one surface side of the base material 11. Next, as shown in FIG. 4, an adhesive 27 is sprayed onto the masking sheet 25. As shown in FIG. 5, the adhesive 27 is applied to the through hole 23 of the masking sheet 25 onto which the adhesive 27 has been sprayed. Then, as shown in FIG. 6, by removing the masking sheet 25 from the base material 11, an outer bonding portion 17 and an inner bonding portion 19 as the bonding portion 15 and a non-bonding region 29 are formed on the base material 11.

[0025] In such a wire harness assembly 1, 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 are provided. Further, the assembly member 5 has a base material 11 and a cover material 13 attached to the base material 11 via a bonding portion 15. Furthermore, the bonding portion 15 has an outer bonding portion 17 disposed along the outer edge of the assembly member 5. And a non-bonding region 29 where the bonding portion 15 is not disposed is provided between the base material 11 and the cover material 13.

[0026] Since the bonding portion 15 has the outer bonding portion 17, the base material 11 and the cover material 13 can be integrated, and the non-bonding region 29 where the bonding portion 15 is not disposed can be formed inside the outer edge of the assembly member 5. For this reason, the amount of the adhesive used in the non-bonding region 29 inside the outer edge of the assembly member 5 can be reduced.

[0027] Therefore, in such a wire harness assembly 1, the cost can be reduced.

[0028] Also, the bonding portion 15 has an inner bonding portion 19 disposed at a position inside the outer edge of the assembly member 5 and avoiding the electric wire 7.

[0029] Since the connecting portion 15 has the inner adhesive portion 19, it is possible to suppress the reduction of the non-adhesive region 29 and minimize the amount of adhesive used, while stably integrating the base material 11 and the cover material 13. In addition, the inner adhesive portion 19 can be used as a guide for arranging the electric wire 7, and the assemblability can be improved.

[0030] Further, the outer adhesive portion 17 has a dividing portion 21 that is divided so as to avoid the electric wire 7.

[0031] The electric wire 7 disposed in the dividing portion 21 is not adhered to the outer adhesive portion 17, so it can move freely at the dividing portion 21. For this reason, the connector 9 provided at the terminal portion of the electric wire 7 can be moved freely, and it is easier to fit the connector 9. In addition, the dividing portion 21 can be used as a guide for arranging the electric wire 7, and the assemblability can be improved.

[0032] 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.

[0033] For example, although the electric wires of the wire harness are four, it is not limited to this, and the number of electric wires may be three or less, or five or more. In addition, although one end side of a plurality of electric wires is aggregated into one connector, it is not limited to this, and a connector may be provided for each of one end sides of the plurality of electric wires.
