BNC Connectors

BNC ConnectorsCurrently, there is no common opinion on the origin of the name of such connectors. The most reliable sources share the point of view that the abbreviation stands for Bayonet Neill-Concelman where bayonet is a type of connection (bayonets were similarly fixed to some types of rifles) while Neill and Concelman are the names of inventors. However, such abbreviation is often treated as the British Naval Connector. BNC connectors are widely used in digital equipment to transmit synchronizing clock signals. In addition to that, BNC connectors are used as input and output connectors as part of digital audio interfaces (SPDIF, in particular). Such connectors may have the characteristic impedance of 75 Ohms and 50 Ohms (the latter are not used in audio equipment). Cable connectors have spacer bar saddles. You will need special tools to mount them on the cable.The connector's design is as follows: There is a thin central signaling contact installed inside a metal case with an external connection clutch (you need to turn it to fasten the cable connection reliably). A contact braid shielding tube is installed on the opposite side of the metal case. A signal track goes through the tube and is inserted into the pin which, in its turn, is connected to the central contact. Another tube is put on the contact tube. Then you need to swage this tube using special tools. The central contact may be coated with nickel, gold or silver. The case itself is usually coated with nickel.Such connectors offer a number of benefits including a low price and quick assembly/disassembly of counterparts. BNC connectors are highly durable and support a wide range of operating temperatures.
