[Figure 4] FIG. 4 is a schematic cross-sectional view of a state in which the wiring board shown in FIG. 3 is attached to a vehicle body. DETAILED DESCRIPTION OF THE INVENTION

[0010] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0011] (First embodiment) A wiring board according to a first embodiment will be described with reference to Fig. 1. As shown in Fig. 1, wiring board 1 is attached to a metal vehicle body 10 and includes a panel 2 that separates a vehicle interior from a front compartment provided in front of the vehicle interior in vehicle body 10, and a wire harness 3 as wiring arranged on panel 2.

[0012] Next, a description will be given of vehicle body 10 to which wiring board 1 of the present embodiment is attached. Vehicle body 10 to which wiring board 1 of the present embodiment is attached is formed by casting in a large mold.

[0013] The body 10, which is formed by casting using a large mold, is strong. Therefore, the partition wall between the passenger compartment and the front compartment does not need to be strong enough to maintain the shape of the body. This means that the body 10 and the partition wall do not need to be integrally formed, and a separate partition wall can be used.

[0014] In addition, since electric vehicles do not have an internal combustion engine, they do not easily get hot and make little noise. For this reason, the car body 10 can use not only metal but also resin for the bulkheads.

[0015] For the reasons mentioned above, this embodiment illustrates a wiring board that is formed by casting and employs a resin panel 2 as a partition wall in a body 10 of an electric vehicle that is not equipped with an engine.

[0016] The vehicle body 10 has a passenger compartment in which the driver's seat, passenger seat, and rear seats are located, and a front compartment provided at the front of the passenger compartment. The vehicle body 10 has no partition wall between the passenger compartment and the front compartment, and an opening 11 is provided. The resin panel 2 is shaped to close the opening 11 between the passenger compartment and the front compartment.

[0017] The plastic panel 2 is provided with bolt holes (=first bolt holes) 21 through which bolts 4 are passed as metallic (conductive) fixing parts for attaching the plastic panel 2 to the vehicle body 10. A plurality of bolt holes 21 are provided along the periphery of the plastic panel 2.

[0018] The wire harness 3 is attached to the passenger compartment side surface of the resin panel 2. The wire harness 3 is formed by bundling a plurality of electric wires with tape or the like. In this embodiment, the wire harness 3 has a trunk line 31 extending in the left-right direction, a branch line 32 branching from the trunk line 31 and extending downward, and a body ground line 33 branching from the trunk line 31. Connectors 34 are attached to both left-right ends of the trunk line 31 and to the terminal of the branch line 32 for connecting to electronic devices arranged in the instrument panel. A terminal 35 having a bolt through-hole (= second bolt through-hole) 351 through which a bolt 4 is passed is attached to the terminal of the body ground line 33. In the example shown in FIG. 1 , the body ground line 33 branches off from the trunk line 31, but this is not limited thereto and the body ground line 33 may branch off from the branch line 32.

[0019] The wire harness 3 is fixed to the plastic panel 2 by a harness clip 5. In the example shown in Fig. 1, the wire harness 3 is fixed to the plastic panel 2 by the harness clip 5, but this is not limiting, and the wire harness 3 may be fixed to the plastic panel 2 by an adhesive or the like.

[0020] Next, a description will be given of a manufacturing process of the above-mentioned wiring board 1 and attachment of the wiring board 1 to the vehicle body 10. In this embodiment, the resin panel 2 is used as a wiring board, and the wires are routed on the resin panel 2 and bundled by wrapping with tape or the like to form the wire harness 3, which is then fixed to the resin panel 2 using the harness clip 5.

[0021] Next, the plastic panel 2 with the wire harness 3 fixed thereto is attached to the vehicle body 10. Bolt holes 12 for passing bolts 4 are provided at the edge of an opening 11 provided in the vehicle body 10 between the passenger compartment and the front compartment. The edge of the plastic panel 2 is overlapped with the edge of the opening 11 provided in the vehicle body 10, and the bolt holes 12 provided in the vehicle body 10 and the bolt holes 21 provided in the plastic panel 2 are overlapped. Furthermore, the bolt holes 351 of the terminal 35 provided at the end of the body earth wire 33 are overlapped with the bolt holes 21 provided on the surface of the plastic panel 2 facing the passenger compartment.

[0022] 2, the bolts 4 are passed through bolt through-holes 351, 21, and 12 provided in the terminal 35, the plastic panel 2, and the vehicle body 10, and fastened using nuts 13. As a result, the body earth wire 33 is electrically connected to the vehicle body 10 via the bolts 4. In this embodiment, two terminals 35 are provided, and therefore two of the five bolts 4 are passed through the bolt through-holes 351 provided in the terminals 35. The remaining bolts 4 are passed through the bolt through-holes 21 and 12 provided in the plastic panel 2 and the vehicle body 10 without passing through the terminals 35, and fastened using nuts 13.

[0023] According to the above-described embodiment, the wire harness 3 can be assembled near the instrument panel simply by attaching the resin panel 2 on which the wire harness 3 is arranged so as to cover the opening between the passenger compartment and the front compartment. Since the resin panel 2 can be grasped by a robot hand, it is also possible to automatically assemble the wiring board 1 to the vehicle body 10. This facilitates the assembly work of the wire harness 3 near the instrument panel.

[0024] According to the above-described embodiment, the vehicle body 10 is the body of an electric vehicle and is formed by casting, which allows the resin panel 2 to be used as a partition between the passenger compartment and the front compartment.

[0025] According to the embodiment described above, the body earth wire 33 is body earth-connected to the vehicle body 10 via the bolt 4. This eliminates the need to connect the body earth wire 33 to the vehicle body 10 separately from the installation of the plastic panel 2, making the assembly process even easier. Also, it is no longer necessary to extend the body earth wire 33 outside the plastic panel 2 in order to connect it to the vehicle body 10.

[0026] According to the embodiment described above, the bolt 4 is passed through the bolt through-hole 21 of the plastic panel 2 and the bolt through-hole 351 of the terminal 35 attached to the end of the body earth wire 33, and the plastic panel 2 is attached to the vehicle body 10. As a result, when attaching the plastic panel 2 with the bolt 4, the body earth wire 33 can be connected to the vehicle body 10 via the bolt 4 simply by passing the bolt 4 through the terminal 35 connected to the end of the body earth wire 33.

[0027] (Second embodiment) Next, a wiring board 1B of a second embodiment will be described with reference to Fig. 3. In Fig. 3, parts equivalent to those of wiring board 1 of Fig. 1 already described in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. As shown in Fig. 3, wiring board 1 includes a resin panel 2 that is attached to a metal vehicle body 10 and separates the passenger compartment of vehicle body 10 from the front compartment, and printed wiring 3B as a plurality of wirings printed on resin panel 2.

[0028] Vehicle body 10 to which wiring board 1B of the second embodiment is attached is also the body of an electric vehicle, similar to the first embodiment, and is formed by casting using a large mold. Resin panel 2 of the second embodiment is similar to that of the first embodiment, and therefore will not be described in detail here.

[0029] The plurality of printed wirings 3B are formed by printing on the plastic panel 2. In this embodiment, some of the plurality of printed wirings 3B extend from the left end of the plastic panel 2 toward the right side and extend to the right end of the plastic panel. Some of the plurality of printed wirings 3B extend from the left end of the plastic panel 2 toward the right side, then bend downward, and extend to the bottom end of the plastic panel 2. Some of the plurality of printed wirings 3B extend from the right end of the plastic panel 2 toward the left side, then bend downward, and extend to the bottom end of the plastic panel 2. Connectors 34 are connected to both ends of the plurality of printed wirings 3B. The connectors 34 are, for example, edge connectors.

[0030] Some of the multiple printed wirings 3B serve as body ground wires 33B, and terminals of the printed body ground wires 33B are provided at the edges of the bolt through holes 21 in the resin panel 2. In this embodiment, three body ground wires 33B are provided, and therefore terminals of the body ground wires 33B are provided at the edges of three of the five bolt through holes 21. Terminals of the body ground wires 33B are not provided at the edges of the remaining bolt through holes 21.

[0031] Next, a description will be given of how to attach the above-described wiring board 1B to vehicle body 10. The edge of plastic panel 2 is placed over the edge of opening 11 provided in vehicle body 10, and bolt through-hole 12 provided in vehicle body 10 is placed over bolt through-hole 21 provided in plastic panel 2. Then, as shown in FIG. 4 , bolt 4 is passed through bolt through-hole 21 provided in plastic panel 2 and vehicle body 10 and fastened using nut 13. As a result, since the terminal of body earth wire 33B is printed on the edge of bolt through-hole 21 of plastic panel 2, body earth wire 33B is electrically connected to vehicle body 10 via bolt 4.

[0032] According to the above-described embodiment, the printed wiring 3B can be assembled near the instrument panel simply by attaching the resin panel 2 on which the printed wiring 3B is printed so as to cover the opening between the passenger compartment and the front compartment. Because the resin panel 2 can be held by a robot hand, the wiring board 1 can also be automatically assembled to the vehicle body 10. This facilitates the assembly work of the printed wiring 3B near the instrument panel.

[0033] According to the embodiment described above, the bolt 4 is passed through the bolt-through hole 21 of the plastic panel 2, and the plastic panel 2 is attached to the vehicle body 10. As a result, by simply attaching the plastic panel 2 with the bolt 4, the body earth wire 33B can be connected to the vehicle body 10 via the bolt 4.

[0034] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0035] For example, the material of the panel that separates the passenger compartment from the front compartment and on which the wire harness 3 and printed wiring 3B are arranged is not limited to resin, but may be metal or carbon.

[0036] In the first embodiment described above, the resin panel 2 is used as a wiring plate for the wire harness 3, but the present invention is not limited to this. The wire harness 3 may be formed using a wiring plate other than the resin panel 2, and then the formed wire harness 3 may be mounted and fixed on the resin panel 2.

[0037] In the second embodiment described above, the printed wiring 3B is printed only on the surface of the plastic panel 2 facing the passenger compartment, but this is not limited to this. The printed wiring 3B may also be provided on the surface of the plastic panel 2 facing the front compartment. One surface of the plastic panel 2 may be a ground surface and a ground wiring surface. Furthermore, the plastic panel 2 may be provided in multiple layers, with the printed wiring 3B provided on both surfaces of each layer.

[0038] In the second embodiment described above, an edge connector is used as the connector 34, but the present invention is not limited to this. A surface-mounted connector may be used as the connector 34. Alternatively, a through-connector that penetrates the resin panel 2 may be used as the connector 34, and the through-connector may connect electronic devices arranged in the passenger compartment and electronic devices arranged in the front compartment.
