Note that the dimensional ratios in the drawings are exaggerated for convenience of explanation and may differ from the actual ratios. Also, in the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals.

[0010] FIG. 1 is a diagram for explaining the connection of the electrical equipment connection device 100 according to this embodiment. The electrical equipment connection device 100 is provided in an in-vehicle connection system 10 configured inside a vehicle, and is a device that relays the wiring of electrical equipment 300 provided inside the vehicle.

[0011] As shown in FIG. 1, the in-vehicle connection system 10 according to this embodiment includes an electrical equipment connection device 100, an electrical connection box 200 (junction box: JB), electrical equipment 300, and a connector 400.

[0012] The electrical equipment connection device 100 is a device for connecting (relaying) the electrical connection box 200 and the electrical equipment 300. FIGS. 2A and 2B are diagrams for explaining the configuration of the electrical equipment connection device 100 according to this embodiment. As shown in FIG. 2A, the electrical equipment connection device 100 includes a substrate 110, a plurality of input terminals 140, a plurality of output terminals 150, a relay circuit 120, and a fuse circuit 130. In this embodiment, the relay circuit 120 and the fuse circuit 130 are configured by general relays and fuses.

[0013] The input terminal 140 is connected to, for example, a connection terminal 410 provided on a connection wire connected to the electrical connection box 200. Also, the output terminal 150 is connected to, for example, a connection terminal 420 provided on a connection wire connected to the electrical equipment 300.

[0014] FIG. 2B shows an example in which the input terminal 140 and the output terminal 150 are concentrated on one side surface in the electrical equipment connection device 100. In the configuration shown in FIG. 2B, for example, it can be flexibly applied to a place where it is difficult to provide the input terminal 140 and the output terminal 150 on both side surfaces at the place where the electrical equipment connection device 100 is installed.

As shown in FIG. 5, the electrical equipment connection device 100 includes a tie band mounting portion 610 to which a tie band 600 (fastening member) can be mounted. Further, the tie band 600 can be mounted on, for example, a wire harness stretched in the vehicle.

[0027] The electrical connection box 200 is a device provided in the vehicle for distributing power from a common power source to each unit (device).

Further, the electrical connection box 200 may include, for example, a fuse section 201. Further, the electrical connection box 200 is connected to the electrical equipment connection device 100 via a connector 400.

The area in this embodiment will be described later.

[0028] The electrical equipment 300 is a device (apparatus) having a predetermined function provided in the vehicle. The electrical equipment 300 is connected to the electrical equipment connection device 100 via a connector 400. Note that when the electrical equipment 300 and the electrical equipment connection device 100 are provided in the same area, they may be connected without passing through the connector 400.

[0029] FIG. 7 is a diagram for explaining a configuration example to which the electrical equipment connection device 100 according to this embodiment is applied. The electrical equipment 300 to which the electrical equipment connection device 100 is applied includes a sliding door, a circulator, rapid charging (equipment, inlet), a power control (unit), a battery heater, and a driver monitoring system.

[0030] Also, in the example shown in FIG. 7, depending on the electrical equipment 300 to be applied, the areas where the electrical equipment 300, the electrical equipment connection device 100, and the electrical connection box 200 (JB) are installed are different. For example, when the electrical equipment 300 is a sliding door, the electrical equipment 300 is set in the door harness (inside the vehicle compartment), the electrical equipment connection device 100 is installed in the floor harness (inside the vehicle compartment), and the electrical connection box 200 is installed in the engine harness (outside the vehicle compartment). Also, a connector 400 is provided at the boundary of the different areas of the door harness, the floor harness, and the engine harness. That is, the electrical connection box 200, the electrical equipment connection device 100, and the electrical equipment 300 are located in different areas, and the electrical equipment connection device 100 is connected to the electrical connection box 200 and the electrical equipment 300 via the connector 400.

[0031] Also, when the electrical equipment 300 is a circulator, the electrical equipment 300 is set in the roof harness (inside the vehicle compartment), the electrical equipment connection device 100 is installed in the instrument panel harness (inside the vehicle compartment), and the electrical connection box 200 is installed in the engine harness (outside the vehicle compartment).

[0032] Also, when the electrical equipment 300 is a rapid charger, the electrical equipment 300 is set in the floor harness (inside the vehicle compartment), and the electrical equipment connection device 100 and the electrical connection box 200 are installed in the instrument panel harness (inside the vehicle compartment). That is, when the electrical equipment 300 is a rapid charger, since the electrical connection box 200 and the electrical equipment connection device 100 are installed in the same area, they are connected without passing through the connector 400.

[0033] Also, when the electrical equipment 300 is a power control, the electrical equipment 300 is set in the rear motor (outside the vehicle compartment), the electrical equipment connection device 100 is installed in the instrument panel harness (inside the vehicle compartment), and the electrical connection box 200 is installed in the engine harness (outside the vehicle compartment).

[0034] Further, when the electrical equipment 300 is a battery heater, the electrical equipment 300 is set in the engine harness outside the vehicle cabin, the electrical equipment connection device 100 is installed in the engine harness inside the vehicle cabin, and the electrical connection box 200 is installed in the engine harness outside the vehicle cabin.

[0035] Furthermore, when the electrical equipment 300 is a driver monitoring system, the electrical equipment 300, the electrical equipment connection device 100, and the electrical connection box 200 are all installed in the instrument panel harness (inside the vehicle cabin). That is, in the case of the driver monitoring system, since the electrical equipment 300, the electrical equipment connection device 100, and the electrical connection box 200 are installed in the same area, the electrical equipment connection device 100 is connected to the electrical connection box 200 and the electrical equipment 300 without passing through the connector 400.

[0036] (Details of the Configuration of the In-vehicle Connection System 10) Next, with reference to FIGS. 8 to 13, the configuration of the in-vehicle connection system 10 will be described in detail while showing each electrical equipment 300 shown in FIG. 7.

[0037] The slide door to which the electrical equipment connection device 100 according to the present embodiment is applied is, for example, the left and right rear door power slide doors.

For example, when the electrical equipment connection device 100 is applied to the circulator 302, the in-vehicle connection system 10 can arrange the relay at the position closest to the electrical equipment 300 (circulator), and can shorten the total wiring length. Furthermore, for the in-vehicle connection system 10, it is not necessary to add an RB (relay box).

[0041] In addition, when the fuse section 201 of the electrical connection box 200 is not provided or not used, a configuration using the second fuse circuit 130b of the electrical equipment connection device 100 may be applied.

Further, the third output terminal 150c is connected to the rapid charging inlet 303 which is the electrical equipment 300, and the fourth output terminal 150d is connected to the ground 310 (GND). Thereby, the electrical equipment connection device 100 can relay the signal line from the electrical connection box 200 to the rapid charging inlet 303.

[0045] The power control unit to which the electrical equipment connection device 100 according to this embodiment is applied is, for example, a unit mounted on a vehicle such as an EV and controls voltage and current, and is composed of, for example, a rear inverter 304. FIG. 11 is a diagram for explaining a configuration example when the electrical equipment connection device 100 according to this embodiment is connected to the rear inverter 304.

[0050] The driver monitoring device to which the electrical equipment connection device 100 according to the present embodiment is applied includes, as the electrical equipment 300, a DMS controller 307 (Driver Monitoring System) and a body control module 308 (BCM). The DMS controller 307 corresponds to a driver monitoring system. As the automation of driving progresses, the driver monitoring system may lead to a decline in the driver's situation recognition ability and driving skills. Therefore, it is a system for safely taking over the operation from the system to the driver and determining whether the driver is in a state where driving is possible. FIG. 13 is a diagram for explaining a configuration example when the electrical equipment connection device 100 according to the present embodiment is connected to the DMS controller 307.
