Abstract: A socket with non-connecting terminal comprises a socket body, two power terminals, a bottom cover, a support, a ground terminal and a top cover in which the power terminals and the ground prong are integrally stamped without terminal tap. The power terminals are placed in the first receptacle and the second receptacle and sealed with the support and the bottom cover. The power blades are exposed outside to be connected to the wall socket. The three slots serve as a power supply to receive other plugs. The integrally stamped ground terminal is housed in the support and sealed by the top cover; the ground prong is exposed outside for linking to the power supply. The three ground slots on the ground terminal will accept the ground prongs from other plugs. When an electrical current flows through this circuit, there is no resistance encountered and no heat generated.

Abstract: A plug having one round-headed copper conductive sheetmetal and two rectangular copper conductive sheetmetals, all contained within injected resin to form a triangle plug with three conductive sheetmetals arranged in triangle protruding forward. The round-headed conductive sheetmetal is punched in one piece with an extended sheetmetal stretched backward and connected to the wire-inlaying end. The two rectangle conductive sheetmetals are punched with the backend stretching upward to form a seamless L-shaped sheetmetal. The backend of the extended sheetmetal is connected with a wire-inlaying end with its opening facing upward, preventing the extended sheetmetals from being damages because of the second twist. With the three conductive sheetmetals wrapped and located at the back of the plug providing a certain degree of strength and each wire-inlaying end being kept in parallel, the wire inlaying process can be completed once.

Abstract: An electric plug blade made of a conductive material has two sections of recesses formed in the rear part of the blade. An insulation material houses the rear part of the blade to define an insulation part, and the front part of the blade remains unhoused by the insulation material for connecting to a wall outlet.
