Phone connector (audio)



In electronics, a phone connector, also known as phone jack, audio jack or jack plug, is a common family of connector typically used for analog signals, primarily audio. It is cylindrical in shape, typically with two, three or four contacts. Three-contact versions are known as TRS connectors, where T stands for ""tip"", R stands for ""ring"" and S stands for ""sleeve"". Similarly, two- and four-contact versions are called TS and TRRS connectors respectively.The phone connector was invented for use in telephone switchboards in the 19th century and is still widely used. In its original configuration, the outside diameter of the ""sleeve"" conductor is 1⁄4 inch (exactly 6.35 mm). The ""mini"" connector has a diameter of 3.5 mm (approx. 1⁄8 inch) and the ""sub-mini"" connector has a diameter of 2.5 mm (approx. 3⁄32 inch).
