The BNC radio frequency coaxial connector was invented in the 1940s and is one of the most popular radio frequency coaxial connectors. BNC is the abbreviation of Bayonet-Neill-Concelman. Bayonet means that the interface adopts a bayonet connection method, Neill and Concelman respectively. He is the inventor of N-type and C-type radio frequency coaxial connectors.
BNC is actually a small version of the C-type connector-while the C-type connector is a bayonet version of the N-type connector. Its biggest feature is its convenient connection. Generally, it can be connected by rotating the connecting sleeve less than one turn. It is suitable for frequent connection and separation occasions, and is the most versatile and cheap product.
BNC has two specifications of 50 and 75 ohms, and they can be mutually matched. 50 ohm BNC can be used in 4GHz occasions, and its applications are very wide, such as flexible networks, inspection equipment, computer peripheral connections, and monitoring systems. Especially in instruments It is widely used in the fields of instrumentation, network and computer information.
The TNC radio freq
uency coaxial connector was invented in the 1950s. TNC is the abbreviation of Threaded-Neill-Concelman. Threaded means that the interface uses a threaded connection method. Neill and Concelman are the inventions of the N-type and C-type radio frequency coaxial connectors, respectively. By.
TNC was invented because BNC produces noise in a vibrating environment. It is a threaded version of BNC and has an application frequency of up to 11GHz. Military and aviation are typical applications, often working in vibrating environments. F head, 75 ohm screw connection RF coaxial connection The standard connector of the CATV system is mainly connected with RG59, RG6 and RG11 RF coaxial cables. There are mainly one-piece (without crimping tube) and two-piece structure (with crimping tube). This connector is economical and low-cost , Easy to install, especially one-piece structure. Other small RF coaxial connector series include SHV, MHV, Mini-UHF.
