Claims

[Claims for Utility Model Registration] (1) A pressing body is provided on the connecting leg side of the power supply cap so as to be able to protrude while being biased in the same direction as the protruding direction of the connecting leg. It is locked in the retracted state by the lock mechanism, and
In a device that releases the evacuation state by passing current through a coil inside the power supply cap, a switch and a high-frequency oscillator that generates high-frequency pulses by the switch are provided on the side of the device body to which the power supply cap is connected, and the power supply cap is connected to the power supply cap. A high frequency receiver is provided in the coil, and when a high frequency pulse is received, a current flows through the coil, and the high frequency oscillator and the high frequency receiver are configured to
A power cap disconnection device characterized in that it is connected via a power cord that supplies power to the main body of the device. (2) A pressing body is provided on the connecting leg side of the power cap so as to be able to protrude while being biased in the same direction as the protruding direction of the connecting leg, and the pressing body is set in a retracted state by a lock mechanism inside the power cap. Along with being locked,
In a device that releases the evacuation state by passing current through the coil inside the power supply cap, a switch is connected to the main body of the equipment to which the power supply cap is connected via an overcurrent generating load in parallel with the equipment load, and the power supply is A power source characterized in that an overcurrent detector is disposed on a power cord connecting a cap and a main body of the device, and when the switch is operated to cause an overcurrent to flow through the power cord, current is caused to flow through the coil. Cap release device. (3) The overcurrent detector consists of a current detection transformer arranged in series on one side of the power cord, and a signal generated on the secondary side of the current detection transformer is used to operate a relay switch that supplies power to the coil. 3.
