The RCA connector is a type of electrical connector commonly used to carry analog audio and video signals. The name refers to the popular name of Radio Corporation of America, which introduced the design in the 1930s. Typically, the output is a plug type connector and the input a jack type connector. These are referred to as RCA plug and RCA jack respectively.
It is also called a phono connector, referring to its early use to connect a phonograph turntable to a radio receiver. As home audio systems became more complex, RCA cables became a standard way to connect components such as radio receivers, amplifiers, turntables, tape decks, and CD players. Their ubiquity led to them also being used for video: connecting analog televisions, videocassette recorders, DVD players, and game consoles. They remain in use as a simple, widely supported means of connection.
In some European countries such as France and Germany, the name cinch is still used as an antonomasia of the Chicago-based manufacturer Cinch, for such a connector and socket.
