The BNC connector is also called the Q9 connector. The full name in English is “Bayonet Nut Connector”, which means bayonet nut connector in Chinese. This is a standard coaxial cable connector. Generally used in video surveillance engineering and network engineering. It is used to realize the anti-interference connection from the device to the cable or from the cable to the device. The BNC connector is often referred to as the thin coaxial cable connector.
The existing standard BNC connectors are generally made of metal materials, and their outer surfaces are relatively smooth. When connecting with the base, the threaded part of the BNC connector needs to be screwed into the base by hand. The BNC header includes:
1. BNC-T type head, used to connect the computer network card and the cable in the network;
2. BNC barrel connector, used to connect two thin cables into a longer cable;
3. BNC cable connector, used for welding or screwing on the end of the cable;
4.BNC terminator, used to prevent the signal from being reflected back and causing interference after reaching the cable fracture.
