Embodiment Construction

[0012] refer to figure 1 , a pressure sensor mounting structure of the present invention, including a base 1, a cavity 2 is provided in the base 1, a pressure sensor 3 is installed in the cavity 2, a sunken cavity 4 is arranged inside the cavity 2, and the sunken cavity 4 is provided with an O-ring 5, the O-ring 5 isolates the pressure sensor 3 from the base 1, and the base 1 is connected with a locking ring 6 that compresses the pressure sensor 3, and the pressure sensor 3 is connected to the circuit board 7 electrical connection. The locking ring 6 is screwed to the base 1 . When installing, first put the reference copper sheet into the base, then put the pressure sensor and the copper ring respectively, and lock the pressure sensor with the locking ring, and make a mark with the marking method after locking; Then, loosen the locking ring and take out the copper ring, pressure sensor, and copper sheet in sequence, then put in the O-ring, pressure sensor, and copper ring, a...

Abstract

The invention discloses a pressure sensor mounting structure. The pressure sensor mounting structure comprises a base internally provided with a hollow cavity, a pressure sensor is mounted in the hollow cavity, a sunk cavity is arranged on the inner side of the hollow cavity, an O-ring is arranged in the sunk cavity and enables the pressure sensor to be isolated from the base, a locking ring for pressing the pressure sensor is connected onto the base, and the pressure sensor is electrically connected with a circuit board. The pressure sensor mounting structure has the advantages that the pressure sensor is isolated from the base through the O-ring and does not directly contact with the inner wall of the base, and accordingly the influences of the base on the pressure sensor are avoided, working stability of the pressure sensor is guaranteed, and the pressure sensor has good measurement precision.

Description

technical field [0001] The invention relates to a sensor installation structure. Background technique [0002] The traditional pressure sensor installation structure includes a base, which has a cavity inside, and a pressure sensor is installed in the cavity. One end of the pressure sensor is in contact with the inner wall of the base, and the other end is pressed by a locking ring. However, in this pressure sensor installation structure, the pressure sensor is in direct contact with the inner wall of the base, so that the pressure sensor is easily affected by the base, reducing its working stability and affecting the measurement accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pressure sensor installation structure, so that the pressure sensor does not directly contact the inner wall of the base, so as to ensure its working stability and have good measurement accuracy. [0004] In order to solve the ...
