High-temperature-resistant waterproof connector for nuclear power vibration sensorTechnical Field
The invention belongs to the technical field of connectors, and particularly relates to a high-temperature-resistant waterproof connector for a nuclear power vibration sensor.
Background
A vibration sensor is a high output impedance sensor, and changes in impedance characteristics can result in changes in sensor performance, reduced technical specifications, or sensor failure. The temperature and the irradiation can influence the structural characteristics of the nuclear power vibration sensor so as to influence the sealing performance of the sensor, and the sensor output impedance is reduced in the composite environment due to the high humidity characteristic of the sensor in the nuclear power working environment, so that the sensor is possibly invalid. The connector is key for signal transmission and conversion of the vibration sensor, and the connector with high-temperature resistance and waterproof steam characteristics is a precondition of long-term stable operation of the nuclear power vibration sensor, but the connector in the prior art does not have good high-temperature resistance and waterproof steam characteristics.
Therefore, there is an urgent need to develop a high temperature resistant waterproof connector for a nuclear power vibration sensor to solve the above problems.
