A pair of phone connectors: A plug (right) is inserted in a socket (jack, left) Note the flat open contact spring parallel to and inside the tip contact spring. When the plug is removed, those contacts close to connect a circuit; such a connection is said to be 'normal'. Inserting the plug connects its tip to one part of that circuit instead. A phone connector, also known as phone jack, audio jack, headphone jack or jack plug, is a family of electrical connectors typically used for.

The phone connector was invented for use in in the 19th century and is still widely used. The phone connector is cylindrical in shape, with a grooved tip to retain it. In its original audio configuration, it typically has two, three, four and, occasionally, five contacts. Three-contact versions are known as TRS connectors, where T stands for, R stands for and S stands for 'sleeve'. Ring contacts are typically the same diameter as the sleeve, the long shank. Similarly, two-, four- and five- contact versions are called TS, TRRS and TRRRS connectors respectively.

The outside diameter of the 'sleeve' conductor is 1⁄4 inch (6. Wynton Marsalis Transcriptions Pdf Writer. 35 millimetres). The 'mini' connector has a diameter of 3.5 mm (0.14 in) and the 'sub-mini' connector has a diameter of 2.5 mm (0.098 in). Contents • • • • • • • • • • • • • • • • • • • • Other terms [ ] Specific models, and connectors used in specific applications, may be termed e.g. Stereo plug, mini-stereo, mini jack, headphone jack, microphone jack, aux input, etc. The 3.5 mm versions are commonly called 'mini-phone'. In the UK, the terms jack plug and jack socket are commonly used for the respective male and female phone connectors.

In the US, a stationary (more fixed) is called a 'jack'. Discrete Mathematics For Computing Rod Hagerty Pdf Free here. The terms phone plug and phone jack are sometimes used to refer to different genders of phone connectors, but are also sometimes used colloquially to refer to and older and the corresponding jacks that connect wired telephones to wall outlets. Phone plugs and jacks are not to be confused with the similar terms phono plug and phono jack (or in the UK, phono socket) which refer to common in consumer hi-fi and audiovisual equipment. The 3.5 mm connector is, however, sometimes—but counter to the connector manufacturers' nomenclature —referred to as mini phono. Military named several styles of this connector under their designation system, as PL-55, PL-68 (used for a T-17 carbon microphone), and PL-540. Modern connectors [ ].

Phone connectors: • 2.5 mm mono (TS) • 3.5 mm mono (TS) • 3.5 mm stereo (TRS) • 6.35 mm (​ 1⁄ 4 in) (TRS) Modern phone connectors are available in three standard sizes. The original ​ 1⁄ 4 in (6.35 mm) version dates from as early as 1878, when an early version was used for the first commercial in New Haven, Connecticut created by George W. Coy, making it perhaps the oldest electrical connector standard still in use, to this day being the most prominent plug connector on mainstream musical equipment, especially on standard models. The current form of the switchboard-plug was patented prior to 1902, when Henry Pl. Clausen received a patent on an improved design. The 3.5 mm or miniature and 2.5 mm or sub-miniature sizes were originally designed as two-conductor connectors for earpieces on since the 1950s, the standard still used today.
