Power Plug Adapter

I am applying 20 lbs force to push the 2.1mm barrel plug into the receiver power base module of the developer kit. Is there something wrong with this connector? This was ordered last year new and I finally got around to using it. this really sucks.. I need either a new power adapter plug or the white power 2.1 mm plug or receiver. The barrel pin does work in other network devices but the module doesn't accept any pins so I assume the module connect specs or off.
