Preferably, the temperature sensing element is provided with a protective sleeve, the protective sleeve is fixedly connected to the lower end of the casing, and the lower end of the protective sleeve is a tapered structure.

Preferably, a sealing ring is provided at the edge of the lower end surface of the housing.

Preferably, the fixing piece is hinged to the housing.

The beneficial effects of the utility model:

By setting the sealing mechanism, after inserting the protective cover into the cable, by pressing against the storage bag, the storage bag contacts the piercing cone and ruptures, so that the sealant stored inside is filled to the protective cover through the channel, Fill the gap between the protective sleeve and the cable to achieve sealing.

By setting the fixing piece, bolts and nuts, the fixed connection of the two fixing pieces can be realized, and the temperature sensor can be fixed on the cable, and the fixing is stable and firm, and it is not easy to fall off, and multiple fixing holes are set, which can be used on cables of different thicknesses. Both can play a very good fixing effect.
