[0002] Sensor connection terminals do play a vital role in connecting sensors and measuring instruments or control systems. They are not only a bridge for signal transmission, but also a key factor in ensuring the stability and reliability of the entire system. When designing sensor connection terminals, in addition to ensuring accurate signal transmission, it is also necessary to consider scalability in multiple aspects to meet ever-changing application needs.

[0003] When the current sensor connection terminal is in use, the connection between the sensor and the connection terminal is not stable enough, which does not meet the requirements of reliable connection and cannot ensure the long-term stable operation of the connection terminal. Therefore, we propose a sensor connection terminal with a fixing hole to solve the above problem. Utility Model Content
