Universal power adapter DC plugs (the kind you always lose)

[hognoxious]

'm referring to the end with two pins on it, that normally plug into a small socket on the end of the cable that comes from the wall wart. You can fit it two ways round to change the polarity. I've had a few adapters, some with straight plugs and some right angled and they all seem to fit, which seems to imply there's a standard of some kind, but the article only refers to the end that goes into the appliance.

The pins are a tad over 1 mm thick, a little over 4mm apart point to point, and 6mm long

Is there a name for this connector and does anybody know where you can get them, specifically the female bit? I want to rig an external battery pack that'll fit my camera, mp3 player, phone and anything else that I [still] have the right end for.

I don't know what the name of the 2 pin connector is specifically, but the 2 pin to coaxial adapters are usually referred to as power tip connecters

Did you see the bit lower down about how there's no apparent common standard?

I'd either pick another standard and solder it to the stubs, or buy a couple of cheap units and canibalise them.

Maplin do them, if I understand your needs correctly. They have several types in kits, an example of which is:

These sort of connectors are normally moulded to the cable for strength, and if you could get one might be difficult to fit to a cable. And expensive, for what it is.

Why not just buy a suitable wall wart from a car boot sale etc and hack the cable off?
