The electrical device is mounted on the vehicle. A ground terminal (first connection portion) is connected to a vehicle body of a vehicle. The device connector (second connection part) is connected to the switching device (external device). The connection switch is connected between the grounding terminal and the equipment connector. When the connection switch is turned on, a current flows through the device connector, the connection switch, and the ground terminal in this order. The switching circuit switches the connection switch from ON to OFF when the voltage between the ground terminal and the device connector becomes equal to or greater than a predetermined voltage.
电气设备搭载于车辆。接地端子(第1连接部)连接于车辆的车身。设备连接器(第2连接部)连接于开关装置(外部设备)。连接开关连接于接地端子和设备连接器之间。在连接开关接通的情况下,电流按设备连接器、连接开关和接地端子的顺序流过。切换电路在接地端子和设备连接器之间的电压变成规定电压以上的情况下,将连接开关从接通切换成断开。
