Need help with atomizer connection idea

[SimianSteam]

So, I'm working on a concept for a mod and I'm stuck on one part. The atomizer connector's going to be going through a strip of brass, making the positive connection through there. I want to use a nutted connector (wish I could buy just the nuts!), but I want to have it be swappable/replaceable, so I don't want to solder the negative connection directly to the adapter. Also, space is at a premium so the shallower it is the better.

So far the best I've come up with is using a regular nutted connector, but then finding some kind of nut cap and putting a small rivet or some such in there to make the negative connection, and running a wire for the negative out the side. This seems like it's a pretty clunky and inelegant solution, though, and probably prone to failure. I'd really like to have the nut and negative connector be one piece.

Any thoughts?

Sand the edge of the nut, solder it to the brass plate (with hole) - now you have a connector that again can screw up and makes replacement a chore.

Locking down a nut to a plate and adding a drop of CA or loctite seems a much more sensible solution to me.

Thanks, but that's not the part I'm having trouble with. It's the connection from the bottom battery contact to the center pin of the atty connection that's the problem.

Something like a pushrod guide tube, or delrin is required inside the connector base - and a copper rivet is likely to be suitable as the pos-pin. Alternately, a stiff bit copper or brass ROD (or heavy wire), or even ALUMINUM rod.
(Since the centerpin is for POSITIVE and is usually UP)

The brass plate to which the nut attaches either uses the body for conductivity, or you run a hefty wire from the brass, inside the body, to the NEGATIVE end of the battery.

And somewhere on the neg-leg is a switch.

I figured it out. Thanks for your help!
