An electrical contacting surface of the electrical terminal as first current carrying part is electrically connected with a contacting surface of an external electrical connector part as second current carrying part via a connecting system. The connecting system includes a stretch-bolt function, which is integrated in one of the current carrying parts. The stretch bolt function is provided with a male screw thread at the extending end, which is configured to be screwed into a female threaded hole of the second current carrying part.
