[0009] (Description of embodiments of this disclosure) First, embodiments of this disclosure will be described.

[0010] (1) A connection structure for connecting multiple vehicle-mounted devices to an electrical connection box mounted on a vehicle, The connecting structure has a substrate and multiple wiring portions fixed to the substrate. The plurality of wiring sections connect each of the vehicle-mounted devices to the electrical connection box.

[0011] In the aforementioned connection structure, the wiring section that connects each vehicle-mounted device to the electrical connection box is pre-fixed to the base material. Therefore, the operator only needs to install the connection structure based on the predetermined positions of the electrical connection box and each vehicle-mounted device to position the wiring section for connection to both the electrical connection box and the vehicle-mounted devices. In other words, the connection structure simplifies the operation of connecting multiple vehicle-mounted devices to the electrical connection box.

[0012] (2) In the connection structure described in (1), The substrate is insulating, thus insulating the wiring portions from each other.

[0013] The aforementioned connection structure can also insulate the wiring sections through the substrate.

[0014] (3) In the connection structure described in (2), Each of the aforementioned wiring sections is composed of busbars. At least a portion of each of the busbars is embedded in the substrate.

[0015] The aforementioned connection structure can provide full circumference insulation for at least a portion of each busbar through the substrate 21.

[0016] (4) In the connection structure described in (3), The busbar has a protrusion that extends outward from the substrate. A bolt insertion hole is formed in the protrusion.

[0017] According to the above connection structure, the operator can use bolts to fix the protrusion to the electrical connection box or vehicle-mounted device.

[0018] (5) In the connection structure described in (3), The connecting structure has bolt insertion holes that penetrate the substrate and the busbar.

[0019] The above-mentioned connection structure can improve the insulation around the bolt insertion hole.

[0020] (Details of the embodiments disclosed herein) 1. First Implementation Method Figure 1 and Figure 2 The first embodiment of the vehicle-mounted system 1 is disclosed. The vehicle-mounted system 1 is a system mounted on a vehicle. The vehicle-mounted system 1 includes an electrical connection box 10 and multiple vehicle-mounted devices 11. The multiple vehicle-mounted devices 11 include a vehicle battery 12, an inverter 13, and a high-voltage auxiliary unit 14. Each vehicle-mounted device 11 is electrically connected to the electrical connection box 10. Power from the vehicle battery 12 is supplied to the inverter 13 or the high-voltage auxiliary unit 14 via the electrical connection box 10.

[0021] The vehicle-mounted system 1 includes a connection structure 20. The connection structure 20 connects multiple vehicle-mounted devices 11 to an electrical connection box 10. The connection structure 20 has a substrate 21 and multiple wiring portions 22 fixed to the substrate 21. The substrate 21 is insulating. The substrate 21 is made of, for example, resin. The substrate 21 insulates the wiring portions 22 from each other.

[0022] Multiple wiring sections 22 connect each on-board device 11 to the electrical connection box 10. Each wiring section 22 is composed of a busbar 23. For example... Figure 3 As shown, at least a portion of each busbar 23 is fully embedded in the substrate 21. This insulates the wiring portions 22 from each other. Furthermore, in Figure 1 and Figure 2 The specific shape of the part of the busbar 23 embedded in the substrate 21 is omitted.

[0023] like Figure 1 As shown, the busbar 23 has a protrusion 24 protruding outward from the base material 21. A bolt insertion hole 25 is formed in the protrusion 24. The bolt insertion hole 25 extends vertically. A bolt fastening part 10A is provided in the electrical connection box 10. The bolt fastening part 10A is located on the upper part of the electrical connection box 10. A bolt fastening part 11A is provided in each vehicle-mounted device 11. The bolt fastening part 11A is located on the upper part of the vehicle-mounted device 11. The connecting structure 20 is mounted on the upper part of the electrical connection box 10 and the vehicle-mounted device 11. The connecting structure 20 is erected between the electrical connection box 10 and the vehicle-mounted device 11. Bolts 80 are inserted into the bolt insertion holes 25 and fixed to the bolt fastening parts 10A and 11A. That is, each protrusion 24 is fixed to the electrical connection box 10 and each vehicle-mounted device 11 using bolts 80.

[0024] In this connection structure 20, the wiring section 22 that connects each vehicle-mounted device 11 to the electrical connection box 10 is pre-fixed to the base material 21. Therefore, the operator only needs to install the connection structure 20 based on arranging the electrical connection box 10 and each vehicle-mounted device 11 in a predetermined position, and can then position the wiring section 22 to connect to both the electrical connection box 10 and each vehicle-mounted device 11. In other words, the connection structure 20 simplifies the operation of connecting multiple vehicle-mounted devices 11 to the electrical connection box 10.

[0025] Furthermore, the connecting structure 20 can also insulate the wiring portions 22 from each other through the substrate 21. The connecting structure 20 can also provide full circumferential insulation for at least a portion of each busbar 23 through the substrate 21. According to the connecting structure 20, the operator can use bolts 80 to fix the protrusion 24 to the electrical connection box 10 or the vehicle-mounted device 11.

[0026] 2. Second Implementation Method In the second embodiment, the configuration where the busbar does not have a protrusion, as described in the first embodiment, will be explained. Furthermore, in the second embodiment, configurations identical to those in the first embodiment will be labeled with the same reference numerals, and detailed descriptions will be omitted.

[0027] Figure 4 and Figure 5 The second embodiment of the vehicle-mounted system 201 is disclosed. The vehicle-mounted system 201 is a system mounted on a vehicle. The vehicle-mounted system 201 includes an electrical connection box 10 and a plurality of vehicle-mounted devices 11.

[0028] The vehicle-mounted system 201 includes a connection structure 220. The connection structure 220 connects multiple vehicle-mounted devices 11 to an electrical connection box 10. The connection structure 220 has a substrate 221 and multiple wiring portions 222 fixed to the substrate 221. The substrate 221 is insulating. The substrate 221 is made of, for example, resin. The substrate 221 insulates the wiring portions 222 from each other.

[0029] Multiple wiring sections 222 connect each vehicle-mounted device 11 to the electrical connection box 10. Each wiring section 222 is composed of a busbar 223. At least a portion of each busbar 223 is embedded in the substrate 221 around its circumference, similar to the first embodiment. Thus, the wiring sections 222 are insulated from each other.

[0030] like Figure 4As shown, bolt insertion holes 225 are formed in the connecting structure 220, penetrating the substrate 221 and the busbar 223. The bolt insertion holes 225 penetrate vertically. The connecting structure 220 is mounted on the upper part of the electrical connection box 10 and the vehicle-mounted device 11. The connecting structure 220 is erected between the electrical connection box 10 and the vehicle-mounted device 11. Bolts 80 are inserted into the bolt insertion holes 225 and fixed to the bolt fastening parts 10A and 11A. That is, each busbar 223 is fixed to the electrical connection box 10 and each vehicle-mounted device 11 using bolts 80.

[0031] According to the connecting structure 220, the insulation around the bolt insertion hole 225 can be improved.
