3.5 mm connectors are sometimes-counter to the connector manufacturers' nomenclature -referred to as mini phonos. RCA connectors are differently-shaped, but confusingly are similarly-named as phono plugs and phono jacks (or in the UK, phono sockets). These naming variations are also used for the 3.5 mm connectors, which have been called mini-phone, mini-stereo, mini jack, etc. Among audio engineers, the connector may often simply be called a quarter inch to distinguish it from XLR, another frequently-used audio connector. The intended application for a phone connector has also resulted in names such as audio jack, headphone jack, stereo plug, headphone jack, microphone jack, aux input, etc. The Institute of Electrical and Electronics Engineers in 1975 also made a standard that was withdrawn in 1997. The American Society of Mechanical Engineers, as of 2007, says the more fixed electrical connector is the jack, while the less fixed connector is the plug, without regard to the gender of the connector contacts. Robert McLeish, who worked at the BBC, uses jack or jack socket for the female and jack plug for the male connector in his 2005 book Radio Production. The 1989 Sound Reinforcement Handbook uses phone jack for the female and phone plug for the male connector. The 1902 International Library of Technology simply uses jack for the female and plug for the male connector. Rings are typically the same diameter as the sleeve. The outside diameter of the sleeve is 6.35 millimetres ( 1⁄ 4 inch) for full-sized connectors, 3.5 mm ( 1⁄ 8 in) for " mini" connectors, and only 2.5 mm ( 1⁄ 10 in) for " sub-mini" connectors. Thus, the number of transmittable signals is less than the number of contacts. The sleeve is usually a common ground reference voltage or return current for signals in the tip and any rings. Since phone connectors have many uses, it is common to simply name the connector according its number of rings: Between the tip and sleeve are 0 to 3 ring contacts. Contacts are insulated from each other by a band of non-conductive material. The sleeve contact is nearest the (conductive or insulated) handle. The tip contact is indented with a groove. A male connector (a plug), is mated into a female connector (a socket), though other terminology is used. Invented in the late 19th century for tele phone switchboards, the phone connector remains in use for interfacing wired audio equipment, such as head phones, speakers, micro phones, mixing consoles, and electronic musical instruments (e.g. TS and TRS plugs of different sizesĪ phone connector is a family of cylindrically-shaped electrical connectors primarily for analog audio signals. When not mated, this spring instead connects to the flat switch contact for detecting a plug. The plug's grooved tip is held firmly by the socket's spring tip contact.
