Fuseless plug with safety circuit breaker

A fuseless plug with safety circuit breaker, comprising a pair of power lines, an upper lid, a lower lid, a first and a second insertion pieces, a thermal reactive spring leaf, an electric conductive sheet, an insulator, a push button end a spring, wherein,

• a first locating ring on said first insertion piece, a second locating ring on said thermal reactive spring leaf, said insulator and a hole on said electric conductive sheet are sequencially locked by a screw on a locking hole on said lower lid, one end of said electric conductive sheet is connected to one of said power lines, said fuseless plug is characterized in that:
• said thermal reactive spring leaf is made of an alloy of two kind of metal material, and is provided with an elastic hook which is bended inwardly;
• while said electric conductive sheet is down folded at the middle point thereof to form a V shaped portion for contacting the body of said thermal reactive spring leaf, and has on the external end thereof a flat sheet portion which can be engaged in said hook in a normal condition, and render said thermal reactive spring leaf to contact said electric conductive sheet, or contrarily, when temperature of the circuit is raised, said thermal reactive spring leaf will be moved away by virtue of the different temperature coefficents of the material of both side surfaces thereof to allow said electric conductive sheet to be moved upwardly to form a broken circuit;
• thereafter, a push button can be pushed down to again render said flat sheet portion to contact said thermal reactive spring leaf which now has recovered its original position, so that they can be electrically connected.
