SAFETY PLUG AUTOMATICALLY PULLED OUT AT SET TIME, PARTICULARLY CONCERNED WITH INSTALLING SOLENOIDS INSIDE A PLUG BODY, AND AUTOMATICALLY OPERATING THE SOLENOIDS AFTER A SET TIME BY AN AUTOMATIC CONTROL DEVICE, IN ORDER TO AUTOMATICALLY PULL THE PLUG OUT OF AN OUTLET

摘要

PURPOSE: A safety plug automatically pulled out at set time is provided to install solenoids automatically operated after a set time inside a plug body, and to protrude a plunger of the plug to a protruded part of a power terminal, thereby automatically pulling the plug out of an outlet. CONSTITUTION: Plural solenoids(3) are operated with external power inputted to a plug(10) inside a body(2), and a plunger(4) is protruded to a protruded part of a power terminal(1) during the operation. A setup button(8) sets an operational time of the solenoids(3). An automatic control device(9) counts the time by the setup button(8), and controls operations of the solenoids(3). The plunger(4) is elastically supported by a spring(6) to be protruded outside the body(2) when power is supplied, and is returned to the inside of the body(2) when the power is intercepted.
