Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the wire harness assembly as in Patent Document 1 above, the arrangement position of the connector with respect to the assembly member is determined according to the mating connector of a specific target member. For this reason, when the wire harness assembly is assembled to another target member, the arrangement position of the mating connector may be different, and the mating connector and the connector may not be fitted. For this reason, it has been necessary to create a wire harness assembly having a different connector arrangement position each time according to the target member to be assembled, and the versatility has been reduced.

[0005] The present invention has been made in view of the problems of such prior art. The object of the present invention is to provide a wire harness assembly that can improve versatility.

Modes 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, for example, a power source mounted on a vehicle and a device, or between devices, i.e., between electrical components (not shown). 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 vehicle door trim, for example.

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

[0012] As shown in FIGS. 1 to 3, the wire harness 3 includes an electric wire 7 and a connector 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 and arranged. 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 wire 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 connector 9 is 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 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. 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 a thickness set to be thinner than that of the base material 11. An adhesive is applied to the surface of the cover material 13 facing the base material 11, and 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. In a state where the cover material 13 is integrally attached to the base material 11, 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 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 connector 9 exposed from the assembling member 5 is fitted to the mating connector in a state where the wire harness assembly 1 is assembled to the target member. At this time, since the electric wire 7 has a predetermined length and is exposed 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 to each other.

[0019] Here, in a conventional wire harness assembly, the arrangement position of the connector 9 with respect to the assembling member 5 is determined according to the mating connector of a specific target member. Therefore, when the conventional wire harness assembly is assembled to another target member, the arrangement position of the mating connector may be different, and the mating connector and the connector 9 may not be able to be fitted. In the conventional wire harness assembly, it was necessary to create a wire harness assembly with a different arrangement position of the connector 9 each time according to the target member to be assembled, resulting in a decrease in versatility.

[0020] Therefore, in the wire harness assembly 1, the assembling member 5 is provided with a lead-out portion 15 that can vary the arrangement position of the connector 9 with respect to the assembling member 5 by pulling out the electric wire 7 arranged inside the assembling member 5 to the outside of the assembling member 5. In the following description, it will be described assuming that the cover material 13 is provided with the lead-out portion 15, but the base material 11 may be provided with the lead-out portion 15.

[0021] The lead-out portion 15 is provided on the cover material 13 along the electric wire 7 in accordance with the arrangement shape of the electric wire 7. The lead-out portion 15 is, for example, a separation portion 17 that can separate the cover material 13 by forming a cut (notch) in the cover material 13. The separation portion 17 is separated by coming into contact with the electric wire 7 by moving the electric wire 7 disposed inside the assembly member 5 toward the outside of the assembly member 5. The electric wire 7 separated from the separation portion 17 is pulled out to the outside of the assembly member 5, and the end position exposed to the outside from the assembly member 5 changes. When the end position of the electric wire 7 from the assembly member 5 changes, the length of the electric wire 7 pulled out to the outside of the assembly member 5 becomes longer. When the length of the electric wire 7 pulled out by the lead-out portion 15 becomes longer, the movement range of the connector 9 disposed outside the assembly member 5 increases, and the arrangement position of the connector 9 with respect to the assembly member 5 can be varied. For this reason, when the wire harness assembly 1 is assembled to the target member, even if the positions of the mating connectors are different, the mating connector and the connector 9 can be fitted by varying the arrangement position of the connector 9. Therefore, the difference in the arrangement position of the mating connector of the target member can be absorbed, and the versatility of the wire harness assembly 1 can be improved. Further, by making the lead-out portion 15 a separation portion 17 that is separated by coming into contact with the electric wire 7, the structure of the lead-out portion 15 can be simplified, and the arrangement position of the connector 9 can be easily varied by the movement of the electric wire 7. In addition, by arranging the separation portion 17 along the electric wire 7, the movement of the electric wire 7 can be stably transmitted to the separation portion 17, and the electric wire 7 can be stably pulled out by separating the separation portion 17.

[0022] As shown in FIG. 4, the separation portion 17 is provided with a restricting portion 19 that restricts the separation of the separation portion 17 by avoiding contact with the electric wire 7. The restricting portion 19 is formed, for example, in a circular shape having a diameter larger than the outer diameter of the electric wire 7 and is composed of a hole formed through the cover material 13. A plurality of restricting portions 19 are provided at intervals along the separation portion 17. When the electric wire 7 is pulled out in the direction of the arrow in FIG. 4 to separate the separation portion 17, for example, the restricting portion 19 is not in contact with the electric wire 7 and the electric wire 7 is disposed thereat. When the electric wire 7 is disposed at the restricting portion 19, since the electric wire 7 is not in contact therewith, the separation of the separation portion 17 can be terminated by the restricting portion 19. By providing the restricting portion 19 in the separation portion 17, the restricting portion 19 can be used as a reference for separating the separation portion 17, and the assemblability can be improved. When separating the separation portion 17 again, the separation portion 17 can be separated up to the next restricting portion 19 by further pulling out the electric wire 7 from the state where the electric wire 7 is disposed at the restricting portion 19. As the restricting portion 19, as shown in FIG. 5, for example, the shape of the cut (notch) of the separation portion 17 may be triangular. This separation portion 17 has its apex portions facing each other with respect to the pulling-out direction of the electric wire 7 in the direction of the arrow in FIG. 5, and the base portion is set to be longer than the outer diameter of the electric wire 7. For this reason, the restricting portion 19 is the base portion of the triangular shape. By providing the separation portion 17 and the restricting portion 19 in this manner, the number of the restricting portions 19 can be increased, and fine adjustment of the arrangement position of the connector 9 with respect to the assembling member 5 can be performed.

[0023] 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 assembling member 5 in which the wire harness 3 is disposed inside. Further, the connector 9 is disposed so as to be exposed outside the assembling member 5. The assembling member 5 is provided with a pulling-out portion 15 that pulls out the electric wire 7 disposed inside the assembling member 5 to the outside of the assembling member 5 and enables the arrangement position of the connector 9 to be varied.

[0024] The electric wire 7 led out to the outside of the assembly member 5 at the lead-out portion 15 has an increased length of the portion led out to the outside of the assembly member 5. When the length of the electric wire 7 led out at the lead-out portion 15 increases, the movement range of the connector 9 arranged outside the assembly member 5 increases, and the arrangement position of the connector 9 with respect to the assembly member 5 can be varied. Therefore, when the wire harness assembly 1 is assembled to the target member, even if the positions of the mating connectors are different, the mating connector and the connector 9 can be fitted by varying the arrangement position of the connector 9.

[0025] Therefore, in such a wire harness assembly 1, the difference in the arrangement positions of the mating connectors of the target member can be absorbed, and the versatility can be improved.

[0026] Also, the lead-out portion 15 is a separation portion 17 that abuts against and is separated from the electric wire 7 by moving the electric wire 7 arranged inside the assembly member 5 toward the outside of the assembly member 5.

[0027] For this reason, the structure of the lead-out portion 15 can be simplified, and the arrangement position of the connector 9 can be easily varied by the movement of the electric wire 7.

[0028] Also, the separation portion 17 is arranged along the electric wire 7 arranged inside the assembly member 5.

[0029] For this reason, the movement of the electric wire 7 can be stably transmitted to the separation portion 17, and the pulling out of the electric wire 7 by the separation of the separation portion 17 can be stably performed.

[0030] Also, a restricting portion 19 for avoiding contact with the electric wire 7 and restricting the separation of the separation portion 17 is provided on the separation portion 17.

[0031] For this reason, the restricting portion 19 can be used as a reference for the separation of the separation portion 17, and the assemblability can be improved.

[0032] As described above, although the present embodiment has been described, 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, in the wire harness assembly according to the present embodiment, the lead-out portion is a separation portion that abuts on the electric wire and is separated, but it is not limited thereto. For example, in a portion where the terminal portion of the electric wire of the assembling member is drawn out to the outside, the base material and the cover material are not adhered but formed in a bag shape. In this bag-shaped portion, a pre-set long surplus portion of the electric wire is accommodated so that the electric wire can be drawn out to the outside. Such a bag-shaped portion may be used as the lead-out portion.

[0034] Further, the number of electric wires of the wire harness is four, but it is not limited thereto, and the number of electric wires may be three or less or five or more. In addition, one end side of a plurality of electric wires is aggregated in one connector, but it is not limited thereto, and a connector may be provided for each of one end sides of a plurality of electric wires. In accordance with such electric wires, a lead-out portion may be provided on the assembling member.
