When the switch is turned on by attaching the voltage detection port cap, the semiconductive region is electrically connected to the accident detection device via the lead wire, and by removing the voltage detection port cap, the semiconductive region is electrically connected to the accident detection device. A cable head voltage detection structure characterized in that when the switch is off, voltage detection is performed by bringing a voltage detection rod into contact with a voltage detection port.
