[0017] Ginseng Figure 4 , 5 As shown, the sensor 30 has a working surface 31, which is in close contact with the first inner wall surface 12 corresponding to the insulating shell 10 to achieve a precise sensing distance, thereby improving the sensing performance of the sensor. The insulating shell 10 has a second inner wall surface 13 facing the first inner wall surface 12. The second inner wall surface 13 is provided with an inclined guide portion 14 protruding toward the first inner wall surface 12 on the side away from the insertion port 11. The insulating seat 20 is provided with an inclined surface 21, and the inclined surface 21 slides along the guide portion 14 to guide the insulating seat 20 to push toward the first inner wall surface 12 to achieve installation in place and a better sealing effect.

[0018] Ginseng Figures 2 to 3 As shown, the insulating seat 20 includes a main body 22, a vertical plate portion 23 and a horizontal plate portion 24 connecting the main body 22 and the vertical plate portion 23. The sensor 30 is arranged on the main body 22, the vertical plate portion 23 closes the insertion port 11, and the end of the cable 40 passes through a circular hole 231 provided on the vertical plate portion 23. A guide slope 232 is provided around the side of the vertical plate portion 23 close to the sensor 30 to guide the insulating seat 20 to be inserted into the insulating housing 10 in the correct position. In this way, the insulating housing 10 cooperates with the vertical plate portion 23 to achieve a fully enclosed sealing effect. In addition, the main body 22 is provided with two grooves 221 at one end away from the insertion port 11, and the main body 22 is provided with a first outer wall surface 223 facing the first inner wall surface 12 of the insulating housing 10.
