The invention, which belongs to the field of sockets, particularly relates to an anti-overheating socket with characteristic of automatic power interruption. The anti-overheating socket comprises a housing. Two electric connecting chambers are arranged in the housing; two U-shaped tubes arranged side by side are arranged in the electric connecting chambers and include arc tubes; and the two ends of the arc tubes are fixedly connected with first straight tubes and second straight tubes. A temperature control box is fixedly connected to the inner bottom surface of each electric connecting chamber and the inside of each temperature control box is filled with mercury. The lower ends of the two first straight tubes are fixedly connected and communicated with the temperature control boxes; the first straight tubes are made of insulating materials; first conductive rings are embedded into the middle parts of the first straight tubes; and second conductive rings are embedded into the lower ends of the first straight tubes. A conductive tube and a conductive rod are connected to the outer side walls of the first conductive rings of the two first straight tubes respectively and fixedly. An insertion hole corresponding to the conductive tube is formed in the side wall of the housing. Therefore, overloaded heating of the socket is avoided; and series results of burning of electrical appliances and even an electric fire due to the human negligence are avoided.
