An RCA connector phono connector, cinch connector, casually A/V jack) is a type of electrical connector commonly used to carry audio and video signals.

Description
The name "RCA" derives from the Radio 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.
History
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-inch phone connectors for many other applications in the consumer audio world when component high-fidelity systems started becoming popular in the 1950s.
However, quarter-inch phone connectors are still common in professional audio, while miniature phone connectors (3.5 mm) have become predominant in personal stereo systems.
Phono plug
The connection's plug is called an RCA plug or phono plug, for "phonograph."
Confusion with Phone plug
Not to be confused with Phone connector (audio) - Tip/Sleeve (TS) or Tip/Ring/Sleeve (TRS) connector - or to a 4P4C connector used for a telephone (which is often, though incorrectly, called "RJ9", "RJ10", or "RJ22").
