Connector for umbilical power system

For the current DIY phono stage project I'm thinking of a two box solution, due in part to the way I've layed the circuit out and partly size/asthetics. So I've been looking for a connector system for the umbilical power cord from the power unit to the 'audio' unit. However since I'm using valves I need it to handle 325V DC 250mA. I've found these NN22AJ at Maplin and according to the manufacturer's specs they're rated for 250V AC 40A. Would these be up to the task or should I look elsewhere/scrap my crazy idea?

 

Maybe the Cliffcon as used by WAD
you can see them here on the back of a WAD amp -

Not sure on the rating of them, maybe worth mailing Cliff Electronics
Heres thier page with the connectors http://www.cliffuk.co.uk/cliffcon.htm

Does say they are for 250v, but maybe they could advise you

 

Cheers for the suggestion Penance. I think I'll contact Cliff Electronics and Neutrik and see if they can tell me what the DC rating is for the connectors.

 

Ok I've come up with an alternative solution of splitting the umbilical into two. So now I have to find a single connector that is capable of handling around 325V DC at 125 mA. I know BNC/TNC connectors are capable of handling 500V AC/DC (at least if I've read the manufacturer's specs right) but I'm not sure if they'd be suitable in terms of handling current. Anyone got any suggestions for what type of connector would be suitable? Any ideas/suggestions welcomed.
