Abstract
The present invention discloses a protective structure, plug, socket and method assuring a live wire and a neutral wire to be powered off simultaneously when overheating. The present invention limits a live wire spring plate from contacting with a live wire conductive plate, and a neutral wire spring plate from contacting with a neutral wire conductive plate, such that when the live wire spring plate and the live wire conductive plate are overheated or the neutral wire spring plate and the neutral wire conductive plate are overheated, the live wire spring plate, the live wire conductive plate, the neutral wire spring plate and the neutral wire conductive plate can be separated apart at a same time.
