Abstract: An electric plug includes a hollow housing, a blade holder shell fitted into the housing to hold two electric wires and two metal blade, and a fuse connected between one electric wire and one metal blade, wherein the housing has a front opening and a rear opening respectively disposed through front and rear side walls thereof; the blade holder shell has a vertical rear side wall press-fitted into the rear opening of the housing, and a front protruding block fitted into the front opening of the housing to hold down the metal blades, keeping the metal blades squeezed in between two side walls of the front opening of the housing and two opposite lateral sides of the protruding block of the blade holder shell; one electric wire has a metal conductor clamp fixedly mounted on one end thereof and hooked in a retaining hole on one metal blade.

Abstract: A tubular lamp assembly is constructed to include a lamp body, and an electric plug connected to electric contact holes at one end of the lamp body, the electric plug including a housing, the housing having a rectangular front receiving chamber, a circular rear receiving hole, a partition wall separating the front receiving chamber from the rear receiving hole, a plurality of receptacle portions integral with one side of the partition wall, and a plurality of through holes through the partition wall and the receptacle portions, a blade holder block installed in the front receiving chamber of the housing, two metal blades installed in the blade holder block and extended out of the housing for connection to an electric socket to receive power supply, the metal blades each having a rear end terminating in two receiving tubes respectively plugged into the receptacle portions of the housing, and a coupler coupled between the housing and the lamp body, the coupler having metal contact pins inserted through the thro

Abstract: A safety plug which includes a first metal contact plate and a second metal contact plate respectively connected to the two conductors of an electric wire, and a first metal blade and a second metal blade for connection to an electric power outlet. A cartridge fuse is connected between the second metal contact plate and the second metal blade. A switch is controlled to force the first metal contact plate into contact with the first metal blade to close the circuit. A base is mounted within a housing to hold the above members therein which has a rear panel and two plug holes on the rear panel for the insertion of an external electric plug for connection the first metal blade and the second metal blade, and a slide controlled to close/open the plug holes of the rear panel.

Abstract: A safety plug including an insulative base frame mounted within an insulative housing to hold a positive contact metal blade and a negative contact metal blade, and a tubular fuse connected between the hot wire of an electric cord and the positive contact metal blade to automatically cut off the circuit upon an electric overload.
