Nextbook Win8.1 tablet dock connector

My Nextbook 10.1" Windows 8.1 (upgraded perfectly to Windows 10) tablet comes with a detachable keyboard which is USB based. I was looking to use the dock connector for an installation in my car, so I put together this little doo-dad.

It uses pogo pins (spring loaded pins) for the connection and you need to install magnets (or just slugs - magnets are in the tablet, not the keyboard) at either end which lock the dock connector in place.

This is meant to be a module for a bigger thing,
