Abstract

PURPOSE:To secure the operation of a temperature fuse by installing a specific temperature fuse installing metal to a protective frame, and installing a temperature fuse insulated by a protective tube to the protective frame holding a heater, by squeezing it to the protective frame folding in two folds. CONSTITUTION:A temperature fuse installing metal 7 is composed to have a U-shape section, and in the temperature fuse installing metal 7, a temperature fuse 9 insulated by a protective tube 8 is housed folding in two folds. And the depth D of the temperature fuse installing metal 7 is made less than two times the diameter d of the protective tube 8 (D<=2d). When the temperature fuse installing metal 7 is screwed up to the outer surface of a protective frame 3, the protective tube 8 is squeezed to the outer surface of the protective frame 3 through the opening side of the temperature fuse installing metal 7. When the temperature of a heater 4 rises suddenly by an abnormal condition, the heat is transmitted to the protective frame 3 holding the heater 4. And since the heat reaches to the protective tube 8 squeezed to the protective frame 3 rapidly, the temperature fuse 9 can be operated securely without receiving the influence of the ambiant temperature.
