The application range of aviation plugs is very wide, and these require the aviation plugs to be applicable in different environments. In order to adapt to the requirements in different environments, the environmental performance of aviation plugs is very important. Temperature, humidity, acid and alkali, vibration shock, immersion, etc. will have a great impact on the function and service life of the aviation plug. The following editor will give you a popular science about the environmental performance of aviation plugs.
1. Temperature
Temperature is a physical quantity that expresses how hot or cold an object is. 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 the aviation plug. In order to ensure the high performance of the connector, the internal metal parts are required to maintain the physical state within a certain temperature, so the temperature range it needs 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 ambient temperature are within the range of 200 degrees, which is an acceptable temperature range.
2. Humidity
Humidity is a physical quantity that expresses the degree of dryness of the atmosphere. Water can corrode metal parts, and it's also somewhat conductive, reducing insulation. In a certain volume of air, at a certain temperature, 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 from the material least affected by 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%.
3. Salt spray
Salt spray is a dispersed system of tiny salt droplets in the atmosphere. When the temperature is 35°C and the salt concentration is 3%, it will cause great corrosion to objects, especially metals. Material composition will affect the electrical performance of aviation plugs. In order to avoid affecting its electrical function in the salt spray environment, it is required to work continuously for at least 48 hours in the salt spray environment artificially made by a specific sodium chloride solution.
4. Vibration and shock
Vibration and shock often affect the electrical contact reliability and robustness of connectors. 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.
5. Dip
Immersion is to immerse the object in the liquid, the nearby water is relatively large, and the action time is relatively short, but this method is the best and most commonly used method to check the airtightness of the object.
In order to ensure the reliability of the use function of the aviation plug and maintain the continuity of the current of the connected parts, usually according to different application objects and application environments, the appropriate shape and structure are selected and applied to appropriate electronic devices. All must meet the electrical performance requirements under different environmental prerequisites.
