Abstract: A receptacle with overload protection includes a bimetallic member mounted on two fixing seats electrically connected to two elastic contact plates of the receptacle. The bimetallic member includes two contacts that normally contact with each other to form a close circuit in the receptacle. When an electric appliance plugged into the two elastic contact plates is overloaded to cause a temperature rise in the receptacle, the two contacts of the bimetallic member automatically separate from each other to form an open circuit in the receptacle, so that power supplied to the electric appliance via the receptacle is interrupted to protect the electric appliance and the receptacle from damage due to overload. The two contacts of the bimetallic member automatically contact with each other again when the temperature at the receptacle is lowered to a safety range.
