An SR connector, or CP connector (from
Russian: ''Соединитель Радиочастотный'',
radio frequency connector) is a type of Russian made RF connector for coaxial cables.
Based on the American
BNC connector, the SR connector differs slightly in dimensions due to discrepancies in

, though with some force they can still be mated.
There are however types of SR connectors that do not resemble their American counterpart.
Most SR connectors are variants of SR-50 (50 Ω) or SR-75 (75 Ω) versions, with the SR-75 typically having a thinner center pin. They often resemble
C connectors in shape, and have threaded inserts similar to

The N connector (also, type-N connector) is a threaded, weatherproof, medium-size RF connector used to join coaxial cables. It was one of the first connectors capable of carrying microwave-frequency signals, and was invented in the 1940s by Pau ...
s.
Further numerical suffixes denote specific kinds of connectors, for instance the CP 75-164 is a much larger high power connector, designed for upwards of 3000W, with a similar appearance to an N or UHF type. The various letters after the number refer to the dielectric material used.
