The CA glue should work. Make sure the wire has no oily residue left on it from it's insulation by wiping it with some iso alchohol. Old CA glue doesn't work well either. Try some fresher glue.

I've noticed that superglue hardens very quickly when used with copper. For example, if I got a hole 0.6mm hole drilled for 0.6mm copper wire and I apply CA to the wire, if won't fit in.
So if you're applying CA to the copper, there's a chance it might have cured by the time you're introducing the other part to it. Try the other way round.

i have to connect to one peice and then bend the copper wire in 3 places

Oh, sorry for the confusion. Yes, CA is short for cyanoacrylate (aka superglue).

Even though superglue bonds well, it can't usually take much bending or similar stress as it sets so hard. If you got decent gluing surfaces and the final assembly doesn't come under constant strain, I can't see why it wouldn't hold. But superglue cures hard and doesn't bend, it snaps. So if possible, do any required bendings before gluing to reduce the chances of popping joints loose, or at least bend so that the joints aren't subjected to it.

Don't forget --- there is still good old fashion 5 minute epoxy. Worked before there was CA, bet it stll does.
