ユーズセンサを提供することを目的とするものである。However, the above-mentioned conventional temperature fuse sensor for high temperature has the following problems. (1) In the case of severe shock or vibration, the wire may break due to the stress of the shock or vibration before the temperature of the device reaches an abnormally high temperature. (2) Fusible metal melted due to the abnormally high temperature of the device may be scattered due to impact or vibration, causing damage between the leader wire @h and 9b or between the leader wire 9a.
%2b and cap 5 may be short-circuited. An object of the present invention is to provide a high temperature temperature fuse sensor that is free from the possibility of such a phenomenon occurring.

ことを特徴とする。[Structure of the Invention] The high temperature fuse sensor of the present invention has the following features:
A temperature fuse made of a fusible metal wire that melts at a predetermined temperature is inserted into one hole of a heat-resistant two-hole insulated tube, and one of the two lead wires made of heat-resistant metal connected to both ends of the fuse is inserted into the two-hole heat-resistant insulated tube. The two lead wires are passed through the other hole of the hole insulating tube, and these two lead wires are buried inside an outer tube made of heat-resistant metal with a heat-resistant insulating filler, and the two-hole insulating tube is placed at the tip of the outer tube. and is covered with a cap made of heat-resistant metal.
