<p>PROBLEM TO BE SOLVED: To provide a safety device for power supply circuit in hybrid vehicle, capable of preventing a connection apparatus and a human body from being damaged and a disaster, such as fire from occurring, if the device is disconnected from the connector-connecting apparatus for power cable. SOLUTION: A power connector 10 includes an insulated housing 3, that houses a socket contact 33 shielded by a shield ring 35, of which the inner periphery is connected to a connection conductor and of which the outer periphery is connected to a shielded wire 43 of the power cable 4 and an electric pole 1, which has conducting properties, and the shield wire 43 and the electric pole 1 are connected to a capacitance measurement/power supply control circuit. The capacitance measurement/power supply control circuit measures the capacitance between the shield wire 43 of the power cable 4 and the electric pole 1 with a converter and, when it is a fixed amount of capacitance or smaller, energization to the power cable 4 is blocked by a current-breaking circuit.</p> |
