<p><P>PROBLEM TO BE SOLVED: To provide an automatic fall-off plug device in which a motor is installed in a receptacle connected to a commercial power supply and a plug pin is mechanically cut off by the motor in order to save power. <P>SOLUTION: When a timer is operated by pushing a starting button, the timer supplies power to a motor 5 after a set time and operates the motor 5. The motor 5 rotates a screw shaft 7 and moves a moving contact body 4 and releases connection of a moving contact of the moving contact body 4 and a fixed contact installed on a plug pin 3. Movement of the moving contact body 4 is restricted by a limit switch, and when power supply is controlled, the moving contact body 4 moves to the left side, and the moving contact and the fixed contact operate a remote contact limit switch 9 installed at a point sufficiently separated, and switch off the power supply of the motor 5. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
