らなる温度ヒユーズ。 A sealed cylindrical metal case, a temperature-sensitive pellet disposed within one end of the metal case, and a temperature-sensitive pellet inserted and fixed into the other open end of the metal case so as to face the temperature-sensitive pellet; between an airtight sealing structure in which a lead wire having a fixed contact at the tip is inserted into the ring and hermetically sealed with glass or ceramic; and an airtight sealing structure that seals the temperature-sensitive pellet and the open end of the metal case. A movable contact is slidably arranged on the inner peripheral surface of the metal case, and a ceramic is compressed and inserted between the movable contact and the temperature-sensitive pellet, and brings the movable contact into elastic contact with the fixed contact of the hermetically sealed structure at room temperature. and a ceramic open circuit spring which is compressed and inserted between the movable contact and the hermetically sealed structure, and which separates the movable contact from the fixed contact when the temperature-sensitive pellet melts. Temperature fuse consisting of.
