Bayonet or BNC? Neil Concelman connectors are commonly found on coaxial cables. Male-type connectors are attached to the ends of basic BNC cables. It has a pin that connects to the cable conductor in the center.

The rotating ring on the outside of the BNC cable tube is capable of locking to female connectors. This type of connector is commonly found on monitors. It aims to improve the accuracy of signals, particularly those sent by the video adapter.
