I thought there was a thread with pics but apparently not....
Even if you buy the specified switchcraft threaded connector and tighten the hell out of it, the connection will not be consistent unless the center pin is in the right state. As tough/sturdy as the threaded switchcraft connector looks, I think it is a weak part and combination.. Having to do this fix is silly..
The fix is to spread the pin apart with a tiny screwdriver or toothpick. The best fix is to wedge a tiny, tiny piece of rubber (from a rubberband) in the pin so it always has just a bit of tension spreading the halves apart. That pin MUST splay to maintain constant contact with the connector ID.
I consider it a must-do mod Before you have problems in the field and ruin a recording.. My v3 was very new when I had the problem.
