Catch RCA

A taken RCA (also called connector RCA or taken CINCH or connector CINCH ) is a electric Connecteur usually used in the field Audio/Vidéo. The name “ RCA ” comes from Radio Corporation off America.

In many uses, this connector is used in substitute with traditional the telephone jack of the time of the manual telephone centres, since the Années 1970 where the readers of audio Cassette of compact living room became popular.

On the majority of the cable S, each end has a male connector RCA . These catches consist of a central Doigt, surrounded by a metal ring. The ring is often in the form of sections, for reasons of flexibility. The female connectors RCA , which one finds on the apparatuses consist of a central hole surrounded by a metal cylinder. This cylinder of the same size that the male part, allows a connection resistant Mécanique and a perfect electric connection. To connect a connector RCA, it is enough to support on the catch. To withdraw it, it is a question of drawing on the catch.

Between the external ring and the central finger of the plug, is located a part filled in general with plastic. The catches are often coloured in the following way:

  • yellow for the composite video,
  • red for the channel stereo right,
  • white or black for the stereo left channel.
This trio (or couples) of catch is found on the majority of the video and audio apparatuses.

One of the problems with the system of connection RCA is that each electrical signal requires its own cable. Even in the simple case of the connection of a reader cassette, 4 cables are necessary, 2 for the entry and 2 for the exit. In a current installation, one leads quickly to a jungle of cables; it is still worse when one wants to transfer from the more complex signals like Vidéo composite (3 cables in each direction). Several tests of combined connectors were carried out, as well in the field of the audio as of the video, but none them became really universal. However, the connector SCART had much success in Europe.
