bayonet connector
The bayonet connector originated in the 19th century for military applications1. It was designed to provide a quick and secure method of connecting electrical systems in military equipment. The name "bayonet" comes from its similarity to the bayonet mounting mechanism used for attaching blades to firearms7.The modern bayonet connector was developed during World War II. In 1944, Paul Neill, who had previously invented the N connector, created a prototype for the U.S. Navy that would become the BNC (Bayonet Neill Constant) connector4. This design featured a constant 50 ohm impedance at frequencies beyond 1 GHz and used a bayonet fastening for quicker connection compared to threaded connectors4.There are several connectors similar to the bayonet type:
BNC (Bayonet Neill-Concelman) Connector: A widely used variant of the bayonet connector, especially in radio systems and as a common video connector4.
Mini-BNC Connector: A smaller version of the standard BNC, taking up about 40% less space5.
C Connector: An improvement on the BNC, developed by Carl Concelman4.
TNC (Threaded Neill-Concelman) Connector: Invented by Neill and Concelman in the late 1950s, it combines the bayonet's quick-connect feature with a threaded coupling for added security4.
ST Connector: Another type of bayonet connector, often used in fiber optic systems3.
These connectors are used in various industries, including aerospace, automotive, consumer electronics, and telecommunications, due to their quick connection and disconnection capabilities, as well as their resistance to vibration and accidental disconnection135.
