BNC connector - Definition and Overview

Male BNC connector

Some authorities expand the BNC abbreviation as Baby Neill-Concelman - it is a lot smaller than N and C connectors. It can also be incorrectly referred to as the Bayonet Navy Connector, British Naval Connector, or the Bayonet Nut Connector.

The BNC connector is one of a larger class of "bayonet connectors", named after the resemblance to the standard twist-on attachment for a bayonet. Named after Paul Neill of Bell Labs (inventor of the N connector) and Amphenol engineer Carl Concelman (inventor of the C connector), the BNC was originally designed as a miniature form of the Type C connector.

It is commonly used on 10base2 thin Ethernet networks, both on cable interconnections and network cards. Other common uses are in professional video connections, for both analog and Serial Digital Interface signals, amateur radio antenna connections, and nearly every piece of electronic test equipment manufactured in the last 35 or so years.

A threaded version of the BNC connector, known as the TNC connector (for Threaded Neill-Concelman) is also available. It has superior performance to the BNC connector at microwave frequencies.
