Claim:
1. A protective structure assuring a live wire and a neutral wire to be powered off simultaneously when overheating, being used to limit a live wire spring plate and a live wire conductive plate from contacting with each other, as well as a neutral wire spring plate and a neutral wire conductive plate from contacting with each other, with the protective structure assuring a live wire and a neutral wire to be powered off simultaneously when overheating comprising: a first limiting element, a second limiting element and a connecting element, wherein the connecting element is connected with the first limiting element and the second limiting element, the first limiting element and the second limiting element abut respectively at the live wire spring plate and the neutral wire spring plate, and the connecting element limits the live wire spring plate and the neutral wire spring plate, allowing the live wire spring plate and the live wire conductive plate to contact with each other, as well as the neutral wire spring plate and the neutral wire conductive plate to contact with each other; when a location between the live wire spring plate and the live wire conductive plate is overheated or a location between the neutral wire spring plate and the neutral wire conductive plate is overheated, if any one location in the first limiting element, the second limiting element or the connecting element is destructed, then the first limiting element, the second limiting element and the connecting element all lose the original limiting function thereof, allowing the live wire spring plate, the live wire conductive plate, the neutral wire spring plate and the neutral wire conductive plate to be separated apart at a same time.
