    • 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.
    • 电源插头组件技术领域本发明涉及一种电源插头组件,包括具有两根电源线的电缆,每根导线的端部具有多个导电金属线; 由正极端子和负极端子组成的端子组,连接部分分别设置在正极和负极端子的后端,连接部分分别连接到电源线的端部的多个导电金属线, 正极和负极端子的表面设有焊接孔; 具有内管和外管的导电套管,绝缘材料设置在内管和外管之间用于绝缘; 在两个端子分别设置在导电套管的外管和内管上之后,进行焊接操作,并且焊接材料通过焊接孔,使得两个端子连接并保持在导电套管上; 通过塑料注射成型形成的外覆盖构件和导电套管的后部,端子组和电缆的前部通过塑料注射成型被外覆盖构件覆盖。 通过改进的电缆连接方法,本发明提供的端子组和导电套筒管,连接强度和焊接速度增加,故障率较低,可确保质量。
