A phone connector is a family of cylindrically shaped electrical connectors primarily for analog audio signals. Invented in the late 19th century for telephone switchboards, the phone connector remains in use for interfacing wired audio equipment, such as headphones, speakers, microphones, mixing consoles, and electronic musical instruments (e.g. electric guitars, keyboards, and effects units). A male connector (a plug), is mated into a female connector (a socket), though other terminology is used. Plugs have two to five electrical contacts. The tip contact is indented with a groove. The sleeve contact is nearest the (conductive or insulated) handle. Contacts are insulated from each other b…

Audio connectors and video connectors are electrical or optical connectors for carrying audio or video signals. Audio interfaces or video interfaces define physical parameters and interpretation of signals. Some connectors and interfaces carry either audio only or video only, whereas others carry both, audio and video. For digital audio and digital video, this can be thought of as defining the physical layer, data link layer, and most or all of the application layer. For analog audio and analog video, these functions are all represented in a single signal specification like NTSC or the direct speaker-driving signal of analog audio. Physical characteristics of the electrical or optical equip…

The DIN connector is an electrical signal connector that was standardized by the Deutsches Institut für Normung (DIN), the German Institute for Standards, in the mid 1950s, initially with three pins for mono, but when stereo connections and gear appeared in the late 1950s, versions with five pins or more were made. The male DIN connectors (plugs) feature a 13.2 mm diameter metal shield with a notch that sets the orientation in which plug and socket can mate. The range of DIN connectors, different only in the configuration of the pins, has been standardized as DIN 41524 / IEC/DIN EN 60130-9 (3-pin at 90° and 5-pin at 45°); DIN 45322 (5-pin and 6-pin at 60°); DIN 45329 / IEC/DIN EN 60130–9 (7…
