摘要（英）：

The utility model provides a bimetallic strip mechanism. The bimetallic strip mechanism is characterized in that the bimetallic strip mechanism is formed by a bimetallic strip portion and a supporting seat, that the bimetallic strip portion comprises a heat generating resistance wire, an insulating wrapper layer, and bimetallic strip, that the insulating wrapper layer is wrapped round the bimetallic strip, that the heat generating resistance wire is wound round the insulating wrapper layer, that the bimetallic strip portion is fixed on the supporting seat, that the supporting seat is equipped with a screw hole, and that the bimetallic strip mechanism is fixed on a electromechanical device by the cooperation between a screw and the screw hole. A thermal relay including a housing and the bimetallic strip mechanism is also provided. The bimetallic strip mechanism is fixed on the housing by a screw and the screw hole disposed on the supporting seat. The bimetallic strip mechanism saves production cost and resolves practical problem on site. In addition, the bimetallic strip mechanism has advantages of simpleness and practicality, easy operation, and increasing on-site work efficiency.
