I have/had two X3i's, and two X30 Highs. I sync all of them constantly. I charge all of them constantly. I even have a Dell Foldable Keyboard that I have to attach via the pin connectors and NEVER have I had a problem with bent pins. I'm incredibly gentle and mindful in all areas dealing with my Axims and placing it on the cradle, cable and keyboard is no exception.
Are you using a 3rd party cable to connect? Are you "man-handling" or otherwise being a bit rough or adsent-minded when connecting it?
If it's due to user error then it's on you, but if it's seriously a defective unit, call Dell and see what they say. Hopefully, you're still under warranty.
If you're issued a refurbished replacement, look at the bottom to make sure the pins are set in firmly. After that, make sure you aren't causing excess wear and tear and possibly causing the problem by not being careful when connecting the unit.
