1. In the design process of the circular aviation connector, the circular aviation connector is designed to meet the requirement of rated current, when there is current flowing through the contact pair, the contact pair will become hot due to the existence of the conductor resistance and the contact resistance.
2. When the heat exceeds a certain limit, it will damage the insulation of the circular aviation connector and form contact to soften the surface coating, causing malfunction.
3. Therefore, to limit the rated current, it is necessary to limit the temperature inside the circular aviation connector that not exceed the specified value of the design.
4. One thing to be aware of when making a selection, it is necessary to limit the temperature inside the circular aviation connector not exceed the specified value of the design.
5. It should be paid more attention in the case of high current, for example, φ3.5mm contact pair, generally stipulated that its rated current is 50A, but in the 5 core, it should be derated by 33%, that’s to say the rated current per core is only 38A. The more the number of cores, the greater the derating.
