Abstract: A method and a structure for positioning and wrapping wire leads involve providing two leads of a transmission wire for transmitting power and/or signal with appropriate orientational limit therebetween by: wrapping a predetermined range of the two leads extending from a predetermined object with one or more segments of strip-shaped net for orientational limit that maintain independent extension and juxtaposition of the two leads, so as to prevent the leads of the transmission wire from entwining with each other after frequent orientational change caused by an external force.

Abstract: Upon completion of the manufacturing of constituent elements of the charging coupler, waterproof members each with a predetermined shape and width are integrally formed, made from an appropriate material, and disposed at a predetermined portion and/or segment of the constituent elements. In consequence, a hermetic seal is effectuated between each of the constituent elements of the waterproof members and a corresponding one of adjacent related elements of the charging coupler to therefore prevent any gap from forming in the charging coupler after long use, thereby preventing intrusion of ambient moisture.
