Usb cable wiggles

I am not sure if this is a problem unique to me…its not really a PROBLEM but it does worry me. The USB cable I use seems to wiggle quite a bit in my digitone. It seems to make a connection just fine but I worry the amount of wiggling it does can cause a problem over time and mess up the connection. Does anyone else have this issue, or do you find that your usb cable fits pretty snugly and securely into the device? Can anyone point me in the direction of what usb cable they use if theirs fit securely? I would love to purchase one that is decent length and tight fitting. The connection on the digitone itself does not wiggle, just the cable which seems to have a lot of…wiggle room…for lack of better term.
