The circular aviation plug is a communication bridge between circuits that are blocked or isolated within the circuit, allowing the current to flow smoothly and achieving the predetermined function of the circuit. It is the most frequently contacted component by electronic engineering technicians. The use of circular aviation plugs can greatly improve design flexibility.

The use of circular aviation plugs eliminates the need for fixed welding between wires or cables, and connectors are used as bridge connections, simplifying the design and production process, simplifying the assembly process of electronic products, and making use more flexible and convenient, while also reducing production costs. If a certain electronic component fails, the aviation plug can be used to quickly replace the failed component without the need to remove the old one and then weld the new one, making it easy to repair and eliminating many troubles. At the same time, there is no need to pay a lot of labor costs.

With the advancement of technology, electrical connectors will continue to be updated and upgraded. If circular aviation plugs are not used, continuous conductors must be permanently connected between circuits. The electronic devices and power supplies at both ends of the connecting wires must be securely connected through welding and other methods, which will bring many inconveniences to production and use. To update and improve, not only disassembly is required, but also additional costs will be added.
