A MEMS pressure sensor tooling fixture

Abstract

This utility model relates to the field of sensor testing technology and aims to provide a MEMS pressure sensor tooling fixture, including a base and a connector. The base has an open mounting cavity for placing the sensor. The connector includes a connecting section connected to the outside of the base and a limiting part located at one end of the connecting section. The limiting part is used to limit the sensor to be located in the mounting cavity. The connecting section includes a first connecting section and a second connecting section. The second connecting section is located between the first connecting section and the limiting part. The outer wall of the mounting cavity of the base is provided with a first external thread, and the inner wall of the first connecting section is provided with an internal thread that matches it. The second connecting section has an external hexagonal and internal circular structure, and the inner diameter of the second connecting section is larger than the major diameter of the internal thread of the first connecting section. The part that is easy to replace and tighten is designed with an external hexagonal structure and does not have an internal thread inside. When disassembling, the wrench clamps the second connecting section, which does not easily deform the first connecting section and cause deformation of its internal thread.
