YADYRTC (Yet another "Do you recognise this connector")

[Cerebus]

Does any recognise this connector:



The face is about 5mm square.

The usage is as a DC supply input to Nikon digital cameras. Perhaps it's a proprietary part, perhaps it's a generic commercial part. I have a very occasional need to power one of my cameras for a long time and I'd rather opt for wiring a suitable connector up to a bench power supply than have yet another single use power supply cluttering up the desk drawer that has become home to the collection of these in my household.
