And at the end of the waterproof isolation thick film 2, a waterproof connecting cloth 21 is fixedly connected. And the other end of the waterproof connecting cloth 21 penetrates to the outside of the upper outer protective housing 1. A filling chamber 3 is formed between the outer protective housing 1 and the waterproof isolation thick film 2. At the top of the upper outer protective housing 1, a filling pipe 31 is embedded, and the filling pipe 31 is communicated with the filling chamber 3. At the top of the upper outer protective housing 1, a protective cover 4 is buckled, and the position of the protective cover 4 corresponds to the position of the outer end of the waterproof connecting cloth 21. At the bottom of the upper outer protective housing 1, a plug-in mounting seat 11 is fixedly connected. At the top of the lower outer protective housing 1, an assembly mounting seat 12 is fixedly connected. The plug-in mounting seat 11 is inserted into the inside of the assembly mounting seat 12.
[0019] In this implementation: The two outer protective housings 1, under the mutual cooperation of the plug-in mounting seat 11 and the assembly mounting seat 12, form the outer protective part of the entire waterproof housing. And the plug-in mounting seat 11 and the assembly mounting seat 12 are used to provide a connection carrier between the two outer protective housings 1. And the waterproof isolation thick film 2 located inside the entire outer protective part, under the mutual cooperation of the waterproof connecting cloth 21, forms an inner protective component for waterproofing the sensor. When installing, the sensor is placed inside the waterproof isolation thick film 2. The filling chamber 3 between the outer protective housing 1 and the waterproof isolation thick film 2 is used to provide a space for filling the filler. Among them, the filler can be epoxy resin, silica gel, etc. At this time, under the action of the filler inside the filling chamber 3, it can wrap the sensor inside the waterproof isolation thick film 2 outside the waterproof isolation thick film 2, so that the sensor inside the waterproof isolation thick film 2 can form a good isolation from the external water vapor, making the sensor in a good sealed state. And the filling pipe 31 is used to provide a conveying channel between the filler and the inside of the filling chamber 3. And the protective cover 4 located outside the outer protective housing 1 is used to limit and block the outer end of the waterproof connecting cloth 21. In addition, under the action of the waterproof isolation thick film 2, the filler in the filling chamber 3 can be isolated from the sensor, which is convenient for the staff to separate the filler outside the sensor when overhauling the sensor.
[0020] A through groove 13 is opened inside the upper outer protective housing 1, and the waterproof connecting cloth 21 penetrates through the outer protective housing 1 through the through groove 13; wherein the through groove 13 is used to provide a through channel for the waterproof connecting cloth 21 to penetrate to the outside.
