`
`Coaxial power connector
`
`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.

`Common DC power connectors
`
`Connector construction and terminology
`
`The connector pairs for barrel connectors are defined in terms of "plugs" and "receptacles"; receptacles are more commonly called "sockets" or "jacks" in the
`United States. Receptacles may be panel-mounted or circuit board-mounted. Plugs are on cables. Some in-line receptacles are also cable-mounted.
`
`There is a long history in electrical engineering of referring to such power plugs — that is to say, plugs with holes instead of prongs — as female,[1] particularly
`regarding coaxial transmission of electricity,[2] and data communication and computer cables.[3] Type N connectors,[4][5] and all IEC 60320 "appliance
`coupler" plugs, and VGA cables with male connectors on the cable and female connectors on the devices[3] are examples of this. That said, while IEC 60320
`provides gender-based standards for higher-voltage plugs (such as the cable plugged into a standard computer power supply), they have not yet defined
`gender-based standards for low-voltage coaxial power connectors such as those discussed herein; i.e., which component is "male" and which is "female". As a
`result, there are varying opinions in this regard. Many industrial suppliers avoid gender terminology[6] but many do not.[7] Similarly, some people view the
`corded plug as female[8] and some perceive it as male.[9] Some, after consideration and surveys, found that user perception of which was male and which
`female was evenly split.[10]
`
`Regardless of user perception surveys, the connector that resembles the male sex organ is the male connector or plug, and the connector it is inserted in is the
`female connector or socket or receptacle.[3]
`
`Power is generally supplied by a plug to a receptacle. Cables are available with one in-line receptacle fanning out to a number of plugs, so that many devices
`may be supplied by one supply. As the use of a plug implies a cable, even a short stub, some power supplies carry panel-mounted receptacles instead to avoid
`this cable, i.e., the normal convention of power from plug to receptacle is reversed. Cables for such cases are available with a plug at each end, although cables
`or adapters with two receptacles are not widely available.
`
`Plug (male)
`
`On the male plug, the outer body is metallic and cylindrical in shape, and comprises one of the two contacts. The second, inside contact is a hollow metallic
`cylinder constructed to accept insertion of the pin in the corresponding male connector. The inner and outer barrels are separated by an insulating layer,
`which is flared at the tip to prevent a short circuit when the plug is inserted or removed.
`
`Socket or receptacle (female)
`
`There is typically a single spring-loaded contact at the side of the female socket and a pin in the center.
`Connector sizes
`
`There are many different sizes of coaxial power connectors. See the table at the end of this article.

`Contact ratings commonly vary from unspecified up to 5 A (11 A for special high-power versions). Voltage is often unspecified, but may be up to 48 V with 12
`V typical. The smaller types usually have lower current and voltage ratings.
`
`It is quite possible that new sizes will continue to appear and disappear. One possible reason that a particular manufacturer may use a new size is to
`discourage use of third-party power supplies, either for technical reasons or to force use of their own accessories, or both.
`
`The sizes and shapes of connectors do not consistently correspond to the same power specifications across manufacturers and models. Two connectors from
`different manufacturers with different sizes could potentially be attached to power supplies with the same voltage and current. Alternatively, connectors of
`the same size can be part of power supplies with different voltages and currents. Use of the wrong power supply may cause severe equipment damage, or even
`fire.
`Common sizes and interchangeability
`
`Generic plugs are often described by their inside diameter, such as 2.1 mm DC plugs and 2.5 mm DC
`(direct current) plugs.
`
`After the two common 5.5 mm OD (Outer Diameter) plugs, the next-most common size is 3.5 mm OD
`with a 1.3 mm ID (Inner Diameter), usually about 9.5 mm in length, although both longer and shorter
`versions also exist. These 3.5 mm OD plugs are normally used for lower voltages and currents.
`Locking and retention features
`
`A ring-shaped "locking detent" or "high-retention feature", present on the barrel of some DC coaxial
`connectors, is a feature intended to prevent accidental disconnection. Typically, this feature is a
`conical cut-back section of the tip, just behind the insulator that separates the inner from outer contact
`surfaces.
`
`Some common DC power connectors
`
`A "lock-ring DC coaxial connector" uses a captive threaded ring or collar to secure the connection between the plug and jack. This design offers strong
`resistance to unplugging when used properly.
`
`A "lock-tab DC coaxial connector" (also called "bayonet lock") offers a compromise that resists unplugging, but which will
`disengage when pulled hard enough. This connector uses small metal tab protrusions on the connector barrel to lock the
`plug in place, requiring a special push-and-rotate motion to engage the locks.
`Standards
`
`There are several standards in existence, such as IEC, EIAJ in Japan and DIN in Germany. More recently, some
`manufacturers appear to have implemented their own system correlating voltage and plug size. In addition, there
`appears to be a trend to standardize DC connector to negative barrel (or sleeve) of a coaxial power connector.
`
`IEC 60130-10
`
`IEC 60130-10:1971 defines five DC power connectors.[11]
`
`Type A: 5.5 mm OD, 2.1 mm ID (with optional screw lock)
`Type A: 5.5 mm OD, 2.5 mm ID (with optional screw lock)
`Type B: 6.0 mm OD, 2.1 mm ID
`Type B: 6.0 mm OD, 2.5 mm ID
`Type C: 3.8 mm OD, 1.1 mm ID
`Type D: 6.3 mm OD, 3.1 mm ID
`Type E: 3.4 mm OD, 1.3 mm ID
`
`EIAJ power connectors
`
`Lock-ring DC coaxial connectors.
`The knurled barrel allows the plug to
`be secured to jacks that have
`mating male threads.
`
`Five plug and matching socket or jack designs are defined by the EIAJ standard RC-5320A (also called JEITA RC-
`5320A). Each of these plugs is used with a specified voltage range. Most manufacturers use a yellow insulating
`material to distinguish these plugs from other similar-looking DC plugs.
`
`EIAJ-01: For 0–3.15 V. 2.5 mm OD, 0.7 mm ID.
`EIAJ-02: For 3.15–6.3 V. 4.2 mm OD, 1.7 mm ID.
`EIAJ-03: For 6.3–10.5 V. 5.0 mm OD, 1.7 mm ID.
`EIAJ-04 (also called JSBP 4): For 10.5–13.5 V. 5.5 mm OD, 3.4 mm ID.
`EIAJ-05 (also called JSBP 5): For 13.5–18 V. 6.5 mm OD, 4.4 mm ID.
`
`Close-up of a yellow-tipped EIAJ
`connector. Note two round adapter pins
`on the opposite end.
`
`EIAJ-04 and 05 have an internal male pin in the plug. The 01 through 03 sizes do not and are similar to the generic plugs in structure. These five EIAJ plugs
`are 9.5 mm in length and have a current rating of 2A.
`
`There are two other, less common, connectors defined by EIAJ; RC-5321 and RC-5322. The latter is designed for both 12 V and 24 V automotive applications.

`The German national standards organization DIN (Deutsches Institut für Normung—German Institute for Standardization) issued DIN 45323, which defines
`two DC power plug and jack (respectively) sizes. At least one of these sizes has a maximum rating of 34 V and 3 A. The information here is inferred from
`catalog references,[12] as the German standard has not been translated into English yet.

`
`Listing of DC coaxial connectors
`
`This list attempts to show all known sizes, and is annotated with some manufacturers producing selected types, since each manufacturer makes its own
`unique subset of the known types. Note that the example part numbers given may have different connector barrel (sleeve) lengths, and are not necessarily
`exact equivalents. There are many more design variants than can be listed in this table, so only a small sampling of part numbers is given.
`
`Connector size is often listed in the format OD (outer diameter) × ID (inner diameter) × L (length of barrel) and expressed in millimeters. Designations may
`vary between manufacturers.
`
`Coaxial plugs that have a male center pin will have another measurement, Center Pin Diameter (CPD). These plugs are often used for higher power
`applications such as portable computers.
`
`There are a number of sizes listed below that appear to be quite similar, and while the tolerances of these connectors are typically indicated as ±0.05 or
`±0.03 mm by the manufacturers, there is still ambiguity as to whether two sizes differing by only 0.05 mm (or where the specification is only given to the
`nearest 0.10 mm) warrants listing them separately here.

`RadioShack sold a line of adapter plugs for universal AC adapters. Each "Adaptaplug" had a single-letter code, but did not provide any other official
`designation, nor did RadioShack publish the complete specifications and tolerances on barrel and pin dimensions. RadioShack's Web site listed the
`diameters to the nearest 0.1 mm, and sometimes differs slightly from the official EIAJ RC-5320A standard dimensions. This list may include some parts
`RadioShack has discontinued but are retained here for completeness.[19]
