[0002] Waterproof water pressure sensor is a water pressure sensor with good waterproof performance suitable for measuring water pressure in real estate residential pipe network. It generally adopts capacitive water pressure sensor. The pressure sensitive element does not contact the circuit board, which makes it easier to waterproof the internal structure, and a waterproof structure is set at each connection of the sensor housing. The tap water pipe network has high requirements for the waterproof performance of water pressure sensors. However, the existing waterproof water pressure sensors of this type have the following problems in actual use:

[0003] First, during the installation process, the connection is simply made with the pipe through the connecting flange, and the stability of the connection is poor. It is very likely that the connection of the capacitive water pressure sensor will become loose due to the high water pressure in the pipe, which is prone to water leakage and seriously affects the normal use of the capacitive water pressure sensor.

[0004] Secondly, the connecting wires used cannot be well stored and organized when not in use, resulting in the connecting wires being exposed to the outside and easily damaged, thereby reducing the service life of the connecting wires. Utility Model Content
