From Thingiverse:


I like this connector:

Get the BNC Female side prepared
Sand down the end of the nitinol. I used a dremel like device from the Freight of Harbors.
fill up the BNC Female side with Solder (This version uses this connector - https://amzn.to/3vf5r6z - This is an affiliate link) - , as soon as you remove the iron , push in the nitinol Add more heat or solder if needed. Give it a few moments to cool.
After it's soldered in place, and you've ensured you didn't short out your outer and inner shield, add 3/64" heat shrink I went with red because it adds 12 Db (This is a joke) Heat Shrink Tubing - https://amzn.to/3v7XBM5 (Also an affiliate link).
After heat shrink is applied, drill a hole in the center of the cover I made for the Nitinol to go through. I still recommend 1mm nitinol.
6 Confirm everything is functional.
7 If it is, super glue the cover to the connector.
Sanding the Nitinol down Right before it's ready to go into the connector is critical. This stuff oxidizes fast.
