Abstract: A female connector for supplying electric power from a power supply to an electric device includes two power supply terminals to supply the electric power, two relays connected to the two power supply terminals, respectively, to control supply of the electric power, and two control electrodes configured to control opening and, closing of the two relays, wherein the two relays are driven by the power supply, and the two control electrodes are electrically coupled to each other through a control terminal of a male connector upon mating between the female connector and the male connector, the electrical coupling of the two control electrodes causing the two relays to be closed to supply the electric power to the two power supply terminals.

Abstract: A connector apparatus includes a receiving connector connected to a power source and including first and second power jack terminals, a control jack terminal, a control switch including first and second contact points, and an insulative spring positioned below the control switch, and an inserting connector connected to an electronic device and including first and second power plug terminals connected in correspondence with the first and second power jack terminals for receiving power from the power source, and a control plug terminal that extends towards the control switch and applies pressure to the insulative spring for causing the first and second contact points to connect and enabling the power from the power source to be supplied to the electronic device. A part of the insulative spring is configured to melt when an electric arc is generated by disconnecting the connection between the first and second contact points.

Abstract: A female connector for supplying received power has a recess, terminals including power terminals for supplying the power, a locking mechanism to lock a male connector that is inserted into the recess in a mated state in response to insertion of the male connector into the recess, and a switching mechanism to supply the received power to the power terminals in an ON state and to insulate the power terminals from the received power in an OFF state. The switching mechanism is permitted to make a transition to the ON state only when the locking mechanism is locking the male connector in the mated state.
