In this way, the travel of the plug into the socket is advantageously limited.
  • the socket preferably has a frustro-conical guide ring surrounding the mouth of the opening, by means of which engagement of the plug in the socket is facilitated by providing a larger target for the plug and also enabling capture of the plug even if the plug is tilted relative to the axis of the socket.
