That is called a dock connector. Unfortunately, in this case the dock connector is part of the logic board and so is not sold separately. We do sell the logic boards [http://www.ifixit.com/iPod-Parts/iPod-Nano-2nd-Gen#0|here] though. We also have a [guide|423|logic board replacement guide] to help you with the swap or any repair attempts you want to attempt. Good luck!
