  • the individual contact element 11 is deflected through the connector housing 22 of the mating connector 7, in particular through a preferably conically shaped opening in the connector housing 22 of the mating connector 7, in which the associated mating contact element 21 is arranged, and thus deflected from a contacting position into a spacing position.
  • the individual contact element 11 is separated from the associated contact section 19 of the passive electrical component 18 .
