Power plug assembly

Abstract

The present invention relates to a power plug assembly, comprises a cable having two power wires, end sections of each wire has plural conductive metal wires; a terminal set composed by a positive terminal and a negative terminal, a connecting section is respectively provided to the rear ends of the positive and the negative terminals and the connecting sections are respectively connected to plural conductive metal wires of end sections of the power wires, the surfaces of the positive and the negative terminals are provided with welding holes; a conductive sleeve tube having an inner tube and an outer tube, an insulating material is provided between the inner tube and the outer tube for insulation; after the two terminals are respectively provided on the outer tube and the inner tube of the conductive sleeve tube, a welding operation is processed and the welding material passes through the welding holes so the two terminals are connected and retained on the conductive sleeve tube; an outer covering member formed by a plastic injection molding and the rear portion of the conductive sleeve tube, the terminal set and the front portion of the cable are covered by the outer covering member via the plastic injection molding. With the improved connecting method of the cable, the terminal set and the conductive sleeve tube provided by the present invention, the connecting strength and the welding speed are increased, and the defective rate is lower and the quality can be ensured.
