Does anyone recognise this connector that is fitted to a set of power sockets on my new (second hand) desk? I think I have found the connector on the internet, as part of the "START" system, but I wonder if it is a more standardised connector as that does not look like a perfect match (no obvious mating locking lug for instance on mine and the keying looks different than the pictures, but hard to tell). Pin spacing is roughly 10mm and current rating seems to be around 5A or less going by the fuses on the power points, and the centre pin is marked as an earth. Does not seem to be an IEC connector of any standard form. I'm after a BS1363 plug end to connect these, or even better an IEC coupler for my UPS, which wasn't included with the desk.
