From a design POV, when having a '+', 'GND', and '-' connection,
then you likely want the ground pin to make contact first.
DIN 5 180 degrees is, in Europe at least, a standard audio connector for consumer audio stuff,
(or was, I see only 3.5 mm phono plugs in the Chinese stuff these days).

The 3 pole XLR (also audio) could work:

<quote>
The female XLR connectors are designed to first connect pin 1 (the earth pin),
before the other pins make contact, when a male XLR connector is inserted.
With the ground connection established before the signal lines are connected,
the insertion (and removal) of XLR connectors in live equipment is possible without picking up external signals (as usually happens with, for example, RCA connectors).

I am using a 5 pole XLR in that way for my gamma spectrum analyzer probe:

I have used the 5 pole 180 degrees DINs to send i2c through the house...
screened audio cable, i2c allows you to set the speed as low as you like..

Always question what will happen if somebody plugs an audio cable in the 5 pole DIN...

Maybe it is often better to get some not so common used connector types,
I have done that for some other high capacity battery powered equipment I designed,
ebay has all sorts of nice connectors.
