ABSTRACT:
A socket connector which can accommodate a first plug connector or a second plug connector has a cylindrical cavity with a first plurality of socket contacts and a second plurality of socket contacts. The second plurality of socket contacts are shorter than the first plurality of socket contacts. The first plug connector has a number of plug contacts arranged for mating engagement with both the first plurality of socket contacts and the second plurality of socket contacts. The second plug connector contains a number of plug contacts arranged only for mating engagement with the first plurality of socket contacts. The socket connector is constructed and arranged so as to allow penetrating travel of the first plug connector fully into the cylindrical cavity so as to engage with the plug contacts the first plurality of socket contacts and the second plurality of socket contacts while limiting penetrating travel of the second plug connector into the cylindrical cavity to a point at which the plug contacts engage the first plurality of socket contacts but the second plurality of socket contacts are neither engaged nor contacted by the second plug connector.
