Das zweite Verbindungselement 3 weist an seinem den Federn 31, 32 abgewandten Ende ein drittes Verbindungselement 5 auf, das bei dem in Figuren 1 und 2 dargestellten Ausführungsbeispiel ebenfalls aus zwei Kontaktfedern 51 (Figur 2) besteht. Beide Kontaktfedern 51 drücken im Nichtbetriebszustand gegeneinander, sie bilden einen Mechanismus, der der Kontaktierung mit Innen- und Außenleiter 61, 62 eines Koaxialkabels 6, wie in Figur 2 dargestellt, dient.The second connecting element 3 has at its end facing away from the springs 31, 32 a third connecting element 5, which in the in FIGS. 1 and 2 illustrated embodiment also of two contact springs 51 ( FIG. 2 ) consists. Both contact springs 51 press in the non-operating state against each other, they form a mechanism of contacting with inner and outer conductors 61, 62 of a coaxial cable 6, as in FIG. 2 represented, serves.

Das zweite und das dritte Verbindungselement 3, 5 bilden eine einstückige Einheit.The second and third connecting elements 3, 5 form an integral unit.

In Figur 2 ist die Struktur des erfindungsgemäßen Verbindungssystems mit seinen wesentlichen Elementen dargestellt. Das zweite Verbindungselement 3 ist in einem Gehäuse 41 eines Steckers 4 integriert, wobei zwei isolierende Teile 7, 71, 72 das zweite und dritte Verbindungselement 3, 5 umschließen und in den Stecker 4 montiert werden. Dieser besteht aus einem Gehäuse 41 mit einem äußeren Schraubgewinde, auf das eine Verschlussmutter 42 aufgeschraubt wird.In FIG. 2 the structure of the connection system according to the invention is shown with its essential elements. The second connecting element 3 is integrated in a housing 41 of a plug 4, wherein two insulating parts 7, 71, 72 surround the second and third connecting element 3, 5 and are mounted in the plug 4. This consists of a housing 41 with an external screw thread on which a lock nut 42 is screwed.

Das schon erwähnte dritte Verbindungselement 5 bildet einen Mechanismus, der ausgelöst durch eine Einführung des Innenleiters 61 des Koaxialkabels 6 den Innenleiter 6 am dritten Verbindungselement 5 befestigt.The already mentioned third connecting element 5 forms a mechanism which, triggered by an introduction of the inner conductor 61 of the coaxial cable 6, fixes the inner conductor 6 to the third connecting element 5.

Ausgelöst durch die Einführung des Innenleiters 61 des Koaxialkabels 6 in das dritte Verbindungselement wird der Außenleiter (insbesondere ein Drahtgewebe) 62 des Koaxialkabels 6 gegen die Federn 51 gedrückt und so ein galvanischer Kontakt zwischen Außenleiter 62 des Koaxialkabels 6 und dem Gehäuse 41 des Steckers 4 hergestellt.Triggered by the introduction of the inner conductor 61 of the coaxial cable 6 in the third connecting element of the outer conductor (in particular a wire mesh) 62 of the coaxial cable 6 is pressed against the springs 51 and so a galvanic contact between outer conductor 62 of the coaxial cable 6 and the housing 41 of the connector 4 is made ,
