Leakage current detection interrupter plug having detachable connect terminals

摘要

An electric plug includes an end block and a power cord. The end block includes a plurality of first connectors and the power cord includes a plurality of second connectors which correspond to the first connectors and detachably connected thereto. The first connectors and second connectors are electrically conductive. One or more first connectors are connected to the second connectors by press-fitting and are retained therewith by friction. Alternatively, the first connectors may be a terminal screw assembly and the second connectors are wires of the power cord.

主权项

1. An electric plug, comprising an end block and a power cord, said end block comprising a plurality of first connectors and said power cord comprising a plurality of second connectors which are corresponding to said first connectors and detachably connected thereto, wherein said first connectors and second connectors are electrically conductive,
wherein at least one of said first connectors is a metal plate connected to a prong mounted on said end block, and at least one of said second connectors is a metal clip which is frictionally retained with said metal plate upon press-fitted therein, wherein said metal clip comprises:
a proximal portion comprising first and second arms, said first arm being curled up to form a first grip for gripping an insulated end of a second bundle of conductive wires of said power cord, said second arm being curled up to form a second grip for gripping and electrically coupling to a bared conductive end of said second bundle of conductive wires of said power cord; anda distal portion comprising a base with first and second tabs extending oppositely therefrom and curled up over said base to form a receptacle for frictionally retaining therein said metal plate, and wherein a free end of said second arm is provided with a finger such that, when said second arm is curled up, said finger is inserted through an aperture formed on said proximal portion of said metal clip and bent over a lower surface thereof.
