How to use a good military circular electrical connector?

ONE. How to use a good military circular electrical connector? Military circular power connectors are very popular as a very popular connector is very popular, but there are many techniques to use circular power connectors, otherwise the service life of military circular power connectors will be greatly shortened.1. During the connector design process, the thermal design of military circular power connectors is intended to meet the requirements of the rated current, because when the current flows through the contact pairs, the pairs of contacts will be heated up due to the conductor resistance and contact resistance. When the heat exceeds a certain limit, it can damage the insulation of the circular power connector, form contacts, soften the surface coating, and lead to failure.3. In fact, in order to limit the rated operating current, limit the temperature rise inside the connector to no more than the value specified in the system design.4. The problem to be noted when selecting is the necessity to reduce the current rating of the multi-pole military circular electrical connector.5. In the current general situation. We should pay more attention to this point. For example, the rated current of φ3.5mm contact pair is usually specified as 50A, but when it is 5 cores, it needs to be reduced by 33%, i.e. the rated current of each core. Only 38A, the more the number of cores, the bigger the derating.
