The environmental performance of aviation plug connector is very important

We all know that aviation plug connector are often used in different environments. In order to ensure that their functions are not disordered and meet the needs of application in various complex and harsh environments, the environmental performance of aviation plug connector is very important. The quality of environmental performance is also an important indicator for judging the quality of aviation plug connector. Today, the editor will share with you the environmental performance of aviation plug connector.

Humidity is a physical quantity that expresses the degree of dryness of the atmosphere. Water will be corrosive to metal components, and it also has a certain degree of conductivity, which can reduce insulation. At a certain temperature in a certain volume of air, the higher the humidity, the more water vapor in the air, which will affect the function of the connector. Therefore, the component material of the connector must be selected with the least influence of water, and the connector must be able to work normally for at least 96 hours at a temperature of about 40 degrees and a relative humidity of 90%-95%.

Salt spray refers to a dispersion system composed of salt-containing tiny droplets in the atmosphere. When the temperature is 35 °C and the salt concentration is 3%, it will cause great erosion to objects, especially metal components, which will Affect the electrical function of the aviation plug connector. In order to avoid affecting its electrical function in a salt spray environment, it is required to work continuously for at least 48 hours in a salt spray environment artificially made by a specific sodium chloride solution.

Temperature, humidity, acid and alkali, vibration and shock, liquid immersion, etc. will have a great impact on the function and service life of aviation plug connector. Temperature is a physical quantity that expresses the degree of coldness and heat of an object. The ambient temperature is different in different seasons and regions. It can change the physical state of the object, which will have a great impact on the efficiency of theaviation plug connector. In order to ensure the high performance of the connector, its internal metal components are required to keep the physical state unchanged within a certain temperature, so the temperature range required for it to withstand is -60 degrees to 200 degrees. After the two components are connected, the current will generate heat and the temperature will rise. This is the working temperature. Generally, the working temperature and the ambient temperature are added within the range of 200 degrees, which is an acceptable temperature range.

Vibration and shock often affect the electrical contact reliability and robustness of the connector. Usually, during the production process, the vibration and shock environment is simulated according to the relevant parameters to check its performance and improve the electrical performance.

Liquid immersion is to immerse the object in the liquid, the nearby moisture is relatively large, and the action time is relatively short, but this method is the best and most commonly used method for overhauling the sealing of the object.

In order to ensure the reliability of the function of the aviation plug connector and maintain the current continuity of the connected components, the appropriate shape and structure are usually selected and applied to the appropriate electronic equipment according to different application objects and application environments, but they must meet different environmental conditions. electrical performance requirements.
