Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensors, in particular to a housing component for a pressure sensor. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. In order to protect the electrical components of the pressure sensor, a housing assembly for the pressure sensor is required.

[0003] According to the description in the pressure sensor housing disclosed in the patent website (authorization announcement number: CN 217819115 U), "The utility model discloses a pressure sensor housing, a pressure head is arranged at the bottom end of the housing, an electrical component is arranged on the inner wall of the pressure head, an electrical connector is arranged at the top end of the housing, a support rod is arranged on the inner wall of the housing, a slider is arranged on the side wall of the support rod, a first spring is arranged at the bottom end of the slider, a second spring is arranged on the inner wall of the slider, a positioning clip is arranged at one end of the second spring, a rubber pad is arranged on the side wall of the positioning clip, a third spring is arranged on the inner wall of the bottom end of the housing, a telescopic block is arranged at one end of the third spring, and an elastic bubble membrane is arranged at one end of the telescopic block; in the technical solution provided by the utility model, the positioning clip is arranged to improve the stability of the electrical component, and the elastic bubble membrane is arranged to improve the sealing performance of the connection, so as to prevent water from easily entering the gap and damaging the internal electrical components."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use of the utility model, the reaction force of the first spring drives the slider to slide downward, which in turn drives the positioning clamp to slide downward, and the reaction force of the second spring makes the positioning clamp fit tightly with the electrical components inside the sensor, thereby clamping and positioning the internal electrical components. However, in actual use, the spring will gradually fatigue due to continuous expansion and contraction and deformation during long-term use, which will deteriorate the elastic force of the spring, thereby deteriorating the clamping force on the electrical components, causing the electrical components of the pressure sensor to shake or fall off when subjected to external force, affecting the normal operation of the pressure detection work. Therefore, it is necessary to improve a shell assembly for the pressure sensor to solve the above problems. Utility Model Content
