The Bayonet-Neil-Concelman, or BNC, connector derives its name from the surnames of the type N inventor Paul Neil and type C inventor Carl Concelman- the "bayonet” refers to the style of locking mechanism employed by this series. Developed in the late 1940s, the BNC is basically a scaled down version of the Type C, and its compact design, easy quick connect/disconnect coupling and economical manufacturing cost have all helped to ensure that it is consistently apllied in telecommunications, satellite, broadcast, radio and antenna systems.
