Info on DC plugs and sockets

Hello friends, Good day to you all.


Is there any info, links or directions on standards for DC plugs and sockets used in electronic appliances?


Like..
ID / OD, length dimensions, current rating, international standard part number etc.,
Different for American and European plugs?


Any information is appreciated.


With best regards,

The standard part of a connector is the interface to its complement - chassis cutouts etc can vary between model and manufacturer for many types. Datasheets are the place to look.


DC power connectors are less stnadardized than mains ones, a sad fact of life. This is mainly due to the very wide range of DC voltages used - you'd need so many standards if every voltage had a different connector.
 
It would be great if there was even a de-facto standard for dual-rail DC power connectors, for instance +/-15V and ground for preamps and the like. There are various barrel connectors for single rail DC. I suppose a 3-pin JST connector would be appropriate on a PCB, but what for a back-panel? An XLR would clearly be a dangerous choice!
