The high-temperature fuse sensor of the present invention has a temperature fuse made of a fusible metal wire that melts at a predetermined temperature inserted into one hole of a heat-resistant two-hole insulating tube, and two wires made of a heat-resistant metal wire connected to both ends of the temperature fuse. One of the lead wires is passed through the other hole of the two-hole insulating tube, and these two lead wires are buried inside the outer tube made of a heat-resistant metal with a heat-resistant insulating filler. An embodiment of the present invention characterized in that the two-hole insulating tube is placed at the tip of the outer tube and covered with a cap made of heat-resistant metal will be described with reference to FIG. 1
2 is an outer tube, 2a and 2b are lead wires, 3 is a filler, 4 is a sealing body, 5 is a cap, 6 is a welded part, and 7 is a temperature fuse.These structures differ from the conventional structure shown in Fig. 2. do not have. In the present invention, the temperature fuse 7 is inserted into one hole of a two-hole insulating tube 9 made of a heat-resistant insulator, and the lead wires 2a, 2b are welded and connected to both ends of the temperature fuse 7. One of the lead wires 2a is passed through the other hole of the two-hole insulating tube 9. The two-hole insulating tube 9 is placed at the tip of the outer tube 1 filled with a heat-resistant insulating filler 3, and is covered with a cap 5 made of a heat-resistant metal. Note that the tip of the two-hole insulating tube 9 is connected to the cap 5.

Since the high-temperature fuse sensor of the present invention has the above configuration, it has the following effects. (1)
Since the temperature fuse 7 is stably supported inside the two-hole insulating tube 9, it will not be broken by impact or vibration. (2) When the temperature fuse blows, the molten soluble metal stays inside the two-hole insulating tube 9 and does not scatter due to shock or vibration, so the molten soluble metal does not short circuit due to shock or vibration. No accidents will occur. (3) Since the two-hole insulating tube 9 is stably fixed within the cap 5, the effects of (1) and (2) above are ensured.
