ABSTRACT:
A fuseless safety magnetic plug has a housing structure divided into a base and a cover, a pair of wire coupling devices, a magnetic device for preventing the plug from overloading, and two prongs for making electrical connections. The wire coupling devices require no instrument or disassembly of the plug for terminating a power cord because the connection can be made simply by inserting ends of the cord into the wire coupling devices from the outside of the plug. The magnetic device comprising a pair of electromagnetic members, a cam mechanism, a plurality of movable plates, a metal stud, a reverse spring, and a load discharging bolt, is mounted within the housing structure for controlling the current flowing through channels thereof and for breaking the circuit if any one of the channels is overloaded, while it resumes normal conduction by pressing down the load discharging bolt over the cover after the trouble is removed therefrom. Moreover, this plug is available for various electrical appliances by setting a current adjusting device thereat or by providing it with a rear socket means therein.
