Plug connector assembly

A plug connection comprising a first plug connector and a second plug connector, wherein the plug connectors each have at least two contact elements, wherein the contact elements of the first plug connector make contact with the contact elements of the second plug connector at contact points in a plug-connected state of the plug connection, wherein the contact elements of the two plug connectors form contact lugs which project into free space and can be elastically deflected, of which a first contact lug of each contact element is part of an inner conductor and a second contact lug of each contact element is part of an outer conductor enclosing the inner conductor in a coaxial arrangement, and wherein the cross sectional surface area of the contact lugs surrounded by a dielectric, is greater than the cross sectional surface area of the sections of the inner conductor enclosed by insulating bodies, such that a substantially constant impedance results.
