Golden RCA Male Plug Audio Connector W Metal Spring Soldering Adapter

AnRCA connector, sometimes called aphono connectororCinch connector, is a type ofelectrical connectorcommonly used to carry audio and video signals. The connectors are also sometimes casually referred to asA/V jacks. The name "RCA" derives from theRadio Corporation of America, which introduced the design by the early 1940s for internal connection of the pickup to the chassis in home radio-phonograph consoles. It was originally a low-cost, simple design, intended only for mating and disconnection when servicing the console. Refinement came with later designs, although they remained compatible.
RCA connectors began to replace the older quarter-inchphone connectorsfor many other applications in the consumer audio world when componenthigh-fidelitysystems started becoming popular in the 1950s. However, quarter-inch phone connectors are still common in professional audio, while miniature phone connectors (3.5mm) have become predominant inpersonal stereosystems.
The connection's plug is called an RCAplugor phono plug, for "phonograph." The name "phono plug" is sometimes confused with a "phone plug" which may refer to a quarter-inch "phone plug" - Tip/Sleeve (TS) or Tip/Ring/Sleeve (TRS) connector - or to a4P4Cconnector used for a telephone (which is often, though incorrectly, called "RJ9", "RJ10", or "RJ22").
