Hi Brett
There is no currently available replacement for these connectors – everyone uses them and will have the same problem. Try switch cleaner in case it is an oxidation issue, but it is probably mechanical damage which would need the socket to be replaced..
Were it me, I would take the unit apart and solder the wires to the motherboard, but this would be unsupported, so we can't give you any instructions. It would also be a bad thing if someone tripped over the cable.
