Most common coaxial power connector, male and female, 5.5 x 2.5 mm Common DC power connectors A coaxial power connector is an electrical power connector used for attaching extra-low voltage devices such as consumer electronics to external electricity.
Also known as barrel connectors, concentric barrel connectors or tip connectors, these small cylindrical connectors come in an enormous variety of sizes. Barrel plug connectors are commonly used to interface the secondary side of a power supply with the device. Some of these jacks contain a normally closed switch; the switch can disconnect internal batteries whenever the external power supply is connected. Connector construction and terminology[edit] Female (plug)[edit] On the female plug, the outer body is a one metal contact. Male (receptacle)[edit] There is typically a single spring-loaded contact at the side of the male connector and a pin in the center corresponding to the intended female plug.
Connector sizes[edit] Standards[edit] RCA connector. An RCA connector, sometimes called a phono connector or cinch connector, is a type of electrical connector commonly used to carry audio and video signals.
The connectors are also sometimes casually referred to as A/V jacks. The name "RCA" derives from the Radio Corporation of America, which introduced the design by the early 1940s for internal connection of the pickup to the chassis in home radio-phonograph consoles. It was originally a low-cost, simple design, intended only for mating and disconnection when servicing the console. Refinement came with later designs, although they remained compatible. Uses[edit] RCA sockets, or jacks, here used for YPbPr video output. In the most normal usage, cables have a standard plug on each end, consisting of a central male connector, surrounded by a ring. As with many other connectors, the RCA has been adopted for other uses than originally intended, including as a power connector, an RF connector, and as a connector for loudspeaker cables. DC connector. A DC connector (or DC plug, for one common type of connector) is an electrical connector for supplying direct current (DC) power.
Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent accidental interconnection of incompatible sources and loads. Types vary from small coaxial connectors used to power portable electronic devices from AC adapters, to connectors used for automotive accessories and for battery packs in portable equipment. Cylindrical connectors[edit] Common DC power connectors. Small cylindrical connectors come in a variety of sizes. Plugs w/ center pins.
