| I think the nearest to these is the type of quick connecting socket and plug are the connectors that are used on welding plants, they have a flange fit for the base terminal and a spigot with a bayonet twist and lock design, there are three sizes but the smallest about 12mm in dia is capable of handling up to 130amps so they should do fine, and welding parts supplier will stock them,i.e. Welding engineering supplies Barking have them, hope this helps.
