BNC Connectors

The BNC connector is named after its inventors, Paul Neill and Carl Concelman, (i.e. "Bayonet Neill Concelman") and is a type of single-pole connector used for coaxial cables. A simple bayonet locking mechanism ensures a solid and rapid connection, typically by rotating the ring on the male connector through 1/4 turn. Often used in connections for digital or radio-frequency signals, these  are widely used in the industrial and entertainment world, especially in antenna connections for wireless systems. The male connectors are generally used on cables and the female connectors are generally chassis-mount types.
