Cigarette lighter socket problem...blowing fuse.

I took my cigar lighter apart as it had come loose from the ashtray panel so I could
tighten it up... I put it back together but must have gotten the pieces inside mixed up somewhat and now as soon as I plug the lighter harness in it blows the fuse (which is shared with the horn, which I use regularly).

Can anyone tell me the order the ceramic spacer, washer, nut and "u" shaped piece go in?

Thanks!
