You have still not said what the problem is. In the right hand picture it looks like you are holding a piece of coax with what maybe a coax connector on the end. The picture is not clear enough to be sure is is a coax connector. I don't know what the significance of the left hand picture is.
If it's not a connector that you can put back on the wire, then maybe you need to solder the ends back on to fix it? Assuming the detached wire is the problem.
