wherein the separate and exchangeable interface has an electrically non-conductive interface body and at least one charging current interface contact which is configured to be connected to the corresponding charging current base contact of the plug base,
wherein the plug base and the interface each have positive guides which together form an insertion funnel configured to align the plug base and the interface in such a way that, in a course of engaging the positive guides to connect the plug base to the interface, an initial angular deviation in alignment of more than 10° is possible, and the initial angular deviation in alignment is ultimately reduced to less than 5° by the insertion funnel.
