[0007] A wire harness assembly 1 according to an embodiment will be described in detail below with reference to the drawings. Note that the dimensional relationships in the drawings are exaggerated for simplicity and may differ from the actual relationships.

[0008] As in Fig. 1, the wire harness assembly 1 according to the present embodiment is used, for example, for a wire harness 3 that electrically connects electrical components (not shown), such as a vehicle-mounted power supply and a device, or a device and a device. The wire harness 3 is arranged in a predetermined shape within a mounting member 5 integrally assembled therewith. The wire harness assembly 1 is mounted on a target member (not shown), such as a door trim of a vehicle.

[0009] As in Fig. 1 to 4, the wiring harness assembly 1 comprises a wiring harness 3 and a mounting element 5.

[0010] As in the Fig. 1 to 3, the wiring harness 3 comprises an electrical cable 7 and a connector 9.

[0011] The electric wire 7 is, for example, a covered electric wire in which an 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, and the plurality of core wires are arranged in parallel. The plurality of electric wires 7 are arranged so that their ends on both sides protrude from the mounting member 5. The plurality of electric wires 7 are arranged so that the ends on one end side are bundled at one position and the ends on the other end sides are branched.

[0012] The connector 9 includes, for example, a housing (not shown) made of an insulating material such as a synthetic resin, and a terminal (not shown) made of a conductive material. The housing can be attached, for example, to a mating housing (not shown) of a connector (not shown) that is electrically connected to an electrical component mounted on the vehicle. The terminal is electrically connected to the end of the electric wire 7 and is housed in the housing. The terminal is electrically connected to a mating terminal (not shown) housed in the mating housing by mounting the housing to the mating housing. A plurality of (five in the present embodiment) connectors 9 are used in correspondence with the ends of the plurality of electric wires 7 that protrude from the mounting member 5.

[0013] As in Fig. 1 to 4, the mounting element 5 comprises a base 11 and a cover 13.

[0014] The base 11 is made of, for example, a foam made of urethane or the like, or a nonwoven fabric made of polypropylene fibers, polyethylene terephthalate fibers, polyester-based fibers, or the like, and has soundproofing and heat-insulating properties. The base 11 is plate-shaped and sized to be disposed within the range of the target member, and is connected to the target member by a fastening means (not shown), such as press-fitting. On one surface side of the base 11, the plurality of (four in the present embodiment) electric wires 7 of the wire harness 3 are arranged in a predetermined shape. The ends of the plurality of electric wires 7, each of the electric wires 7 being arranged on the base 11, are exposed from an outer edge of the base 11 by a predetermined length, and the connectors 9 are arranged outside the base 11.

[0015] The cover 13 is made of, for example, a film made of vinyl chloride, polyethylene, or the like, or of a closed-cell foam or an open-cell foam made of polyethylene, polypropylene, polystyrene, elastomer, or the like, and has sound-absorbing and heat-insulating properties. The cover 13 is plate-shaped and has a size corresponding to that of the base member 11 so that the cover 13 is arranged in the region of the target member, and a thickness less than that of the base member 11. An adhesive is applied to a surface of the cover 13 facing the base 11. The cover 13 is attached to one surface side of the base 11 such that the plurality of electric wires 7 are clamped between the cover 13 and the base 11.In a state where the cover 13 is firmly attached to the base 11, the plurality of electric wires 7 arranged in a predetermined shape are held between the base 11 and the cover 13. Therefore, the mounting member 5 can protect the electric wire 7 of the wire harness 3 and maintain the shape of the arrangement of the electric wire 7.

[0016] The connector 9, which protrudes from the mounting member 5, is connected to a mating connector in a state where the wire harness assembly 1 is assembled with the target member. Since the electrical wire 7 is exposed from the outer edge of the mounting member 5 by a predetermined length at this time, the connector 9 can move freely, facilitating the attachment of the connector 9 to a mating connector. By connecting the connector 9 to the mating connector, the electrical components are electrically connected to each other.

[0017] In a conventional wire harness assembly, a base or a cover does not have a structure for holding an electric wire of a wire harness arranged inside a mounting member. Therefore, when the base and the cover are firmly connected (fixed to each other), the electric wire may move between the base and the cover, and the shape of the electric wire assembly may be deformed. When the shape of the electric wire deforms, the position of the connector of the wire harness with respect to the mounting member changes. When the wire harness assembly in which the position of the connector has changed is mounted to a target member, the position of the connector differs from that of the mating connector, and it is difficult to assemble the connectors.

[0018] On the other hand, in the wire harness assembly 1 according to the present embodiment, the base 11 and / or the cover 13 is / are formed with a holding portion 15 that holds the electric wire 7 of the wire harness 3 disposed inside the mounting member 5. In the following description, it is assumed that the holding portion 15 is provided in the base 11, but the holding portion 15 may also be provided in the cover 13.

[0019] The holding portion 15 is provided on a surface side of the base 11 facing the cover 13. The holding portion 15 is provided in the base 11 along the electric wire 7 according to the arrangement shape of the electric wire 7. The holding portion 15 is a groove 17 extending along the electric wire 7 and capable of accommodating the electric wire 7 therein. The groove 17 is open at both end sides (connector 9 side) at both ends of the electric wire 7. The electric wire 7 is accommodated in the groove 17 constituting the holding portion 15 before the base 11 and the cover 13 are joined together. In a state where the electric wire 7 is held by the holding portion 15, the arrangement shape of the electric wire 7 with respect to the mounting member 5 is maintained.Therefore, when the base 11 and the cover 13 are joined (fixed), the electric wire 7 does not move between the base 11 and the cover 13, and the arrangement shape of the electric wire 7 is not deformed. When the shape of the electric wire 7 is not deformed, the position of the connector 9 of the wire harness 3 with respect to the mounting member 5 does not change. Therefore, in a state where the wire harness assembly 1 is mounted to a target member, the position of the connector 9 coincides with the position of the mating connector, and the connector 9 can be easily mounted. In addition, since the holding portion 15 is the groove 17 extending along the electric wire 7 to receive the electric wire 7, the portion where the electric wire 7 is arranged can be prevented from protruding from an outer surface of the mounting member 5 in a state where the base 11 and the cover member 13 are joined.Therefore, the size of the wiring harness assembly 1 can be reduced.

[0020] An example of the groove 17 is shown in the Fig. 5 to 7. The Fig. The groove 17 shown in Fig. 5 is formed by a cut on one surface side of the base 11. The electric wire 7 is accommodated in the cut-shaped groove 17 for press-fitting. The cut-shaped groove 17 has a high adhesion with the electric wire 7. Therefore, the movement of the electric wire 7 can be stably restricted. Fig. The groove 17 shown in Fig. 6 is formed in a V-shaped cross section on one surface side of the base 11. The V-shaped groove 17 has a high adhesion with the electric wire 7 and requires only a small force to insert the electric wire 7 into the groove 17. Therefore, it is possible to improve the ease of assembly while restricting the movement of the electric wire 7. Fig.The groove 17 shown in FIG. 7 is formed in a U-shaped cross section on one surface side of the base 11. The U-shaped groove 17 requires little force to insert the electric wire 7 into the groove 17. Therefore, ease of assembly can be improved. The groove 17 can have any shape as long as the electric wire 7 can be accommodated therein.

[0021] The wiring harness assembly 1 according to the present embodiment includes a wiring harness 3 having an electric wire 7 and a connector 9 electrically connected to one end of the electric wire 7, and a mounting member 5 in which the wiring harness 3 is arranged. The mounting member 5 includes a base 11 and a cover 13 fixedly provided on one surface side of the base 11. The base 11 and / or the cover 13 includes / include a holding portion 15 that holds the electric wire 7.

[0022] In a state where the electric wire 7 is held by the holding portion 15, the arrangement shape of the electric wire 7 with respect to the mounting member 5 is maintained. Therefore, when the base 11 and the cover 13 are assembled, the electric wire 7 does not move between the base 11 and the cover 13, and the arrangement shape of the electric wire 7 is not deformed. When the shape of the electric wire 7 is not deformed, the position of the connector 9 of the wire harness 3 with respect to the mounting member 5 does not change. Therefore, in a state where the wire harness assembly 1 is mounted to a target member, the position of the connector 9 coincides with the position of the mating connector, and the connector 9 can be easily attached.

[0023] Therefore, the electric wire 7 in the wiring harness assembly 1 can be held stably by the mounting member 5.

[0024] The holding section 15 is a groove 17 running along the electrical cable 7 for receiving the electrical cable 7.

[0025] Therefore, it is possible to prevent the area where the electric wire 7 is arranged from protruding from the outer surface of the mounting member 5 in a state where the base 11 and the cover 13 are firmly connected, thereby reducing the size of the wire harness assembly 1.

[0026] In the above-described embodiment, the holding portion 15 is provided in the base 11, but the present invention is not limited thereto, and the holding portion 15 may be provided in the cover 13. The holding portion 15 may be provided on both the base 11 and the cover 13.

[0027] In the above-described embodiment, the holding portion 15 is the groove 17, but the present invention is not limited thereto. For example, the holding portion 15 may be a pair of gripping portions or the like that protrude toward the electric wire 7 to grip the electric wire 7, and the holding portion 15 may have any shape as long as the electric wire 7 can be held thereby. In a case where the holding portion 15 is a pair of gripping portions, a plurality of pairs of gripping portions may be arranged along the electric wire 7 according to the arrangement shape of the electric wire 7.

[0028] 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 embodiments, one end sides of the plurality of electric wires 7 are combined into one connector 9, but the present invention is not limited thereto, and the connector 9 may be provided at each of the one end sides of the plurality of electric wires 7.

[0029] Although the present invention has been described above with reference to the embodiment, the present invention is not limited to this, and the configuration of the parts may be replaced by any configuration having a similar function as long as it falls within the scope of the claims.
