Abstract: The present invention discloses a power supply cut system for a vehicle, which comprises power supply cutting means 13 including a power supply cutting portion 15 provided in a vehicular electric component circuit 1 on an upper stream than a connector connecting portion 4 toward a power supply to make the vehicular electric component circuit 1 non-conductive, and a control unit 14 for controlling the power supply cutting portion 15, and lock detecting means 12 as cut signal inputting means for entering a power supply cut signal to the control unit 14 in a connected or disconnected state of the connector connecting portion 4. When the lock detecting means detects the lock released state, the vehicle electric component circuit 1 is made non-conductive on the upper stream than the connector connecting portion 4 toward the power supply.

Abstract: The connector assembly includes a first connector (10) with female terminals (10e), upstream from a power supply (2) in a circuit for vehicle electric equipment. The assembly includes a second connector (11) with male terminals (11d), downstream from the power supply in the circuit. The second connector is mated with the first connector. The first and second connectors include a connector connection interconnecting the power supply and a load (6).

Abstract: A power supply cut system for a vehicle in which a power supply line is set to a non-conducting state when an adapter supplied with power from a power supply for the vehicle is attached to a power supply socket. In the power supply cut system, power supply cut means is provided for setting the power supply line to the non-conducting state when the adapter is attached to the power supply socket and for setting the power supply line to a conducting state by completely loading the adapter in the power supply socket after attaching the adapter to the power supply socket.
