Electrical properties of aviation plugs

Electrical performance mainly includes rated current, working voltage and so on.

1. Rated current:

Generally refers to the current value of the contact part of the aviation Waterproof Plug that can be loaded for a long time. The rated current should be selected according to the current input and output load of the device, and then the rated current of the Waterproof Connector of the aviation plug should be selected according to the current load of the conductor. This is the primary consideration of selection parameters, rated current is proportional to the diameter of the contact. If the contact is copper alloy, its conductivity relative to pure copper is smaller, so it cannot be calculated according to the electrical standard wire rated current standard, but need to be calculated according to different materials divided by a certain coefficient.

2. Working voltage:



Operating voltage is another key indicator of the aviation plug Circular Connector, which refers to the ability of the contact to withstand the rated voltage of the device, as well as the ability between the contact and the housing. Note that aviation plugs are called "operating voltage" and not "rated voltage" because they only function as conductors and do not generate electricity. In order to ensure that the aviation plug can work safely and reliably under the working voltage, the aviation plug will be designed and manufactured in accordance with the voltage value of a certain number higher than the working voltage.
