It is quite possible that new sizes will continue to appear and disappear. EIAJ-02: For 3.15–6.3 V. 4.2 mm OD, 1.7 mm ID.

), Also used in older Alcatel phones (3DS07008A?AA, 3DS09371A?AA, 3DS10628A?AA), Also used for Canon CA-570 Charger (Output: 8.4V 2A), Used in Acer Aspire V5 adapter and some Hikvision 48V NVRs, Philmore Coaxial Power Plug 3.0mm I.D./5.5mm O.D. One common question that is asked of Techs at Digi-Key is to trying to verify the correct replacement wall mount AC to DC power supply. ], Used for Sony PSP Charger (Input: 100-240VAC, Output: 5VDC @ 1500mA for PSP 1000, 2000, 3000), used in Miniware TS100 soldering iron by e-Design, RadioShack sold a line of adapter plugs for universal AC adapters. Connector size is often listed in the format OD (outer diameter) × ID (inner diameter) × L (length of barrel) and expressed in millimeters. There are several standards in existence, such as IEC, EIAJ in Japan and DIN in Germany. Voltage is often unspecified, but may be up to 48 V with 12 V typical. I used a "5.5mm/2.1mm" jack for my project. A 'lock-ring DC coaxial connector' uses a captive threaded ring or collar to secure the connection between the plug and jack.

.

Please make sure the power supply is de-energized before trying any of these methods. Dc Barrel Plug Size Chart. This means that the entire tip will not go into a 2.1 mm plug, however will go into a 2.5 mm plug. [9] Some, after consideration and surveys, found that user perception of which was male and which female was evenly split.

This is made more difficult by the fact that the two most common sizes of plugs at 2.1 mm ID x 5.5 mm OD and 2.5 mm ID x 5.5 mm OD. 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. If you've got the "barrel type" (a large round plug with a hole in it, and a socket with a pin in the center) they are specified by the OD of the barrel, and the diameter of the pin.

This design offers strong resistance to unplugging when used properly. 0 Comment. .410 is not really a gauge, except by convention. Some mention barrel length as being important whereas others focus on the inner and outer diameter.

The connector pairs for barrel connectors are defined in terms of 'plugs' and 'receptacles'; receptacles are more commonly called 'sockets' or 'jacks' (US). The staff may or may not be competent to help you :-/. A coaxial power connector is an electrical power connector used for attaching extra-low voltage devices such as consumer electronics to external electricity. There are also 5.5/2.5 types, so you really do need to measure them.What I'd do is take either your laptop, or your AC power block and cables, with you to Radio Shack, and visually compare what you have with the components they sell. The sizes and shapes of connectors do not consistently correspond to the same power specifications across manufacturers and models. [15], Learn how and when to remove these template messages, Learn how and when to remove this template message, "Telecom 101 Telecommunications Book - ISBN 9781894887038", "Connectors for frequencies below 3 MHz. Soldering a barrel plug onto battery 35000 35 selecting the proper size welding cables power supply for your led strip right ac adapter and plug for your dc. The information here is inferred from catalog references,[12] as the German standard has not been translated into English yet.[when?].

206, Samsung Laptops (many), for instance 400B2B, found in an ISP specific modem/router, 12VDC power connector, manufactured by Compal, unknown standard, Mini-ITX motherboards (e.g. By Eva | October 30, 2018.
There are many more design variants than can be listed in this table, so only a small sampling of part numbers is given. More recently, some manufacturers appear to have implemented their own system correlating voltage and plug size. [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]. If you slide this into the end of a 2.1 mm ID plug it will be snug and would not fall out when tipped up. A 'lock-tab DC coaxial connector' (also called 'bayonet lock') offers a compromise that resists unplugging, but which will disengage when pulled hard enough.

Test Lead Powered by Discourse, best viewed with JavaScript enabled. Also known as barrel connectors, concentric barrel connectors or tip connectors, these small cylindrical connectors come in an enormous variety of sizes. 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. 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. You can buy one and get an Adapter (2.1 to 2.5, or 2.5 to 2.1) in case you buy the wrong one, or there are a couple tricks that can help identify which size you have. Most manufacturers use a yellow insulating material to distinguish these plugs from other similar-looking DC plugs. In addition, there appears to be a trend to standardize DC connector to negative barrel (or sleeve) of a coaxial power 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. The internal diameter of a 12 gauge shotgun barrel is therefore equal to the diameter of a lead ball weighing 1/12 pound, which happens to be .729" (Or in British: Bore.) Power is generally supplied by a plug to a receptacle.

Five plug and matching socket or jack designs are defined by the EIAJ standard RC-5320A (also called JEITA RC-5320A). The difficult specification to find on many of these power supplies is what size if the inner diameter of the plug / connector. 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. It sure would be nice if someone could write up an instructable on how to correctly identify these and what is important when looking for replacement parts like these. [original research? I've been reading a lot of conflicting information as to what really matters when your trying to find a replacement connector component.

Plugs are on cables. Coaxial plugs that have a male center pin will have another measurement, Center Pin Diameter (CPD).

When placing the test lead in the 2.5 mm plug you will see a noticeable gap around the lead.

There are many different sizes of coaxial power connectors (see table at end of this article).

EIAJ-04 and 05 have an internal male pin in the plug. Typically, this feature is a conical cut-back section of the tip, just behind the insulator that separates the inner from outer contact surfaces.

[clarification needed] This list may include some parts RadioShack has discontinued but are retained here for completeness.

I used a "5.5mm/2.1mm" jack for my project. When placed in a 2.5 mm ID plug the toothpick is loose and will fall out when tipped.

These plugs are often used for higher power applications such as portable computers. Most test leads you will find have a diameter of 2 mm and fit in both the 2.1 and 2.5 mm plugs so you have to look at the gap. We use cookies to provide our visitors with an optimal site experience. 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. Reply The first thing you need to figure out is what the things are called. There are also 5.5/2.5 types, so you really do need to measure them. Choosing The Right Ac Adapter And Plug For Your Dc Device. 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. I have no idea what the "tube" type are called.. From my experience, the plug can't be too long, but it can be too short.

The difficult specification to find on many of these power supplies is what size if the inner diameter of the plug / connector. It is the actual diameter of the bore in decimal inches. 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".
