Female audio jack connections for PICAXE programmer cable
No, there is no standard.

You sould be able to tell from inspection which is the sleave.  That will be connected to the outer shell.  That's almost certainly the long connector at left-most, since it's intended to connect to the shield of the audio cable.

As for which of the other two is tip and ring, ohm them out.  You should be able to stick a wire in the connector far enough to hit the ring spring.  The remaining pin is the tip.

Or, plug in a plug and see which pins on your connector end up being connected to which wires coming out of the plug.  Ohm out the plug and wires if need be.  That's easier than ohming out a socket.
