Well knock me over with a feather! This hare brained scheme actually appears to work at first blush, Some notes, the plug is a bit odd in that the bendable leads are female (as opposed to normal connections which are male), so you need to drag the wire from the connector to the end of the bendable lead to make the connection. But other than that as this sketch demonstrates this appears to work. If you download this you can export the 2 custom parts from the temp parts bin which will at least give you a male barrel connector breadboard icon (and its associated female connector if you actually want to try connecting it). You can (and probably should) move the plug to top in part->raise and lower as that is how it is designed to look plugged in. The connection doesn't appear to care as in the sketch it is the wrong way but still connects. The schematic view is truly ugly as I'm no artist, if one of you artistic types would like to come up with a better schematic view I would be most appreciative . I tried to get across the jack connects to the plug but as I said its ugly. Its also currently hard to reproduce if you make changes with Inkscape. I have a perl script that does a number of things (removes pxs and inlines style commands, as the first breaks fonts and the second breaks bendable leads (as does most anything else come to that ). Even then manual editing is required because the perl isn't entirely correct yet although it is getting closer. Consider this experimental for the moment. I'll probably try and cobble together wall wart and battery parts that can use this (as that is the primary use case as far as I can see). Luckily I remembered to try and load this file before posting, as it was broken. I needed to get the new plug blessed by loading it in to parts editor and exporting it and then using the exported version of the file. My original unblessed part loads fine but won't reload as part of a sketch when saved. This at least reloads for me so hopefully it will for you as well.
