The plug 15 is fixedly installed inside the threaded sleeve 13, and a pin 16 is fixedly installed at one end of the plug 15. During the connection process, the threaded sleeve 13 is first screwed into the second threaded groove 22 inside the fixed sleeve 21 at one end of the second connector 19 to achieve a preliminary threaded connection. The pin 16 in the plug 15 is snap-fitted into the pin groove 20 inside the second connector 19 to ensure the stability of the electrical connection. In order to further enhance the stability of the connection, the connection part is also designed with a first arc-shaped clamping plate 23 and a second arc-shaped clamping plate 24.

A connecting plate 31 is fixedly mounted on the outer wall of movable ring 30, and an open ring 32 is fixedly mounted on the outer wall of connecting plate 31. By pushing movable ring 30, it can be moved along data cable 29, thereby adjusting the position and length of the data cable. To secure the data cable, simply snap it into place inside open ring 32.

[0044] Finally, a pressure probe is fixedly mounted on the other end of the pressure sensor body 11 to measure pressure. Electrical connections are established between the pressure sensor body 11, pins 16, and data cable 29. When the pressure probe measures pressure, the measurement data is transmitted to the data cable 29 through the electrical connection between pins 16 and pin slots 20. The data is then transmitted to subsequent processing equipment for processing and analysis.
