[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides the following technical solutions: A sealed sensor assembly includes a cable main body 1, a fixing mechanism 2 is arranged on one side of the cable main body 1, and a protection mechanism 3 is arranged on one side of the fixing mechanism 2;

[0023] A cable outlet end 101 is arranged on one side of the cable main body 1, and a sensor main body 102 is arranged on one side of the cable outlet end 101.

[0024] The cable main body 1 is arranged inside a hot melt pipe 201, and the cable outlet end 101 is arranged inside the hot melt pipe 201.

[0025] The sensor main body 102 is arranged inside the fixing mechanism 2, and the sensor main body 102 is arranged inside the hot melt pipe 201.

[0026] It needs to be further explained that: One single sensor main body 102 or multiple sensor main bodies 102 are placed in the fixing mechanism 2. The fixing mechanism 2 is melted after being heated at 300 °C and then condensed. The original hollow pipe becomes a solid cylinder, wrapping all the sensor main bodies 102 inside. Since a part of the length of the fixing mechanism 2 is at the position of the cable outlet end 101 before hot melting, after condensation, the solder joints of the sensor main body 102 and the cable outlet end 101 are also wrapped inside, forming an integral assembly.

[0027] Please refer to Figures 3-4 , the present utility model provides the following technical solutions:

[0028] The fixing mechanism 2 includes a hot melt pipe 201 and a positioning groove 202. The hot melt pipe 201 is arranged on one side of the cable main body 1, and a positioning groove 202 is opened at the top of the hot melt pipe 201.

[0031] The protective sleeve 302 is arranged on one side of the fixing mechanism 2, and the protective sleeve 302 is arranged on the top of the hot-melt pipe 201.

[0032] It should be further explained that: the cable body 1 and the cable outlet end 101 are inserted into the connection groove 303 opened on one side of the protective sleeve 302 and pass through the protective cover 301, and then the cable outlet end 101 is welded to the sensor body 102. The sensor body 102, the solder joint, the cable outlet end 101 and the protective cover 301 are completely sealed by melting the fixing mechanism 2 at high temperature, so that the three become an integral sealed sensor element, which facilitates the cable body 1 and the solder joint to form an integral through the fixing mechanism 2, and increases the anti-pulling force of the cable body 1.

[0033] Working principle: When a sealed sensor assembly is in use, first, a cable outlet end 101 is arranged at one end of the cable body 1. The cable outlet end 101 facilitates the connection between the cable body 1 and the sensor body 102.

The fixing mechanism 2 is provided to facilitate the sealing of the cable outlet end 101 and the sensor body 102. A protection mechanism 3 is arranged on the top of the fixing mechanism 2. The protection mechanism 3 is provided to facilitate the protection of the cable body 1.

[0034] When it is necessary to seal and protect the cable outlet end 101 and the sensor body 102, first, the cable body 1 and the cable outlet end 101 are inserted into the connection groove 303 opened on one side of the protective sleeve 302 and pass through the protective cover 301, and then the cable outlet end 101 is welded to the sensor body 102. The sensor body 102, the solder joint, the cable outlet end 101 and the protective cover 301 are completely sealed by melting the fixing mechanism 2 at high temperature, so that the three become an integral sealed sensor element, which facilitates the cable body 1 and the solder joint to form an integral through the fixing mechanism 2, and increases the anti-pulling force of the cable body 1. This device facilitates the sealing and protection of the cable outlet end 101 and the sensor body 102.
