    • A plug structure comprises a seat body, an electric power line and a housing, wherein the front end of the seat body includes at least two conductive plates, the inside of the seat body has a main fuse electrically connected to the conduct plate and a backup fuse, and the electric power line can be set up at the rear end of the seat body and clipped by the contraction plates respectively installed on the two sides of the rear end of the seat body; therefore, when the housing is sleeve installed towards the seat body from the electric power line, the contraction plate squeezes the electric power line due to the structure at the rear end of the housing such that the zigzag tooth-wise pattern configured on the inner surface of the contraction plate can tightly press upon the surface of the electric power line so the electric power line may not be easily pulled out from the rear end of the seat body.
