Der Leitkörper besitzt darüber hinaus einen Ableitabschnitt, der mit einem ebenfalls im Gehäuse angeordneten Ableiter verbunden ist. Der Kontaktträger kann von der Gehäuseinnenseite in den Flansch eingesteckt sein. Er kann dort verklipst sein. Die Klipsverbindung des Kontaktträgers innerhalb des Flansches ist von eigenständiger Bedeutung. Der Kontaktträger weist einen Halteabschnitt auf, der unter Zwischenlage des am gehäuseinnenseitigen Stirnabschnitt des Flansches anliegenden Einleitabschnitts des Leitkörpers den Stirnrand des Flansches zumindest teilweise übergreift. In einer bevorzugten Ausgestaltung wird der Halteabschnitt des Kontaktträgers von einem Ringkragen ausgebildet. Der Leitkörper kann von einem Federblech ausgebildet sein. Das Federblech kann von einem Stanzbiegekörper ausgebildet sein mit einer oder mehrerer Stanzöffnungen, von deren Rändern radial einwärts gerichtete Federzungen abragen. Diese Federzungen können auf dem gehäuseinnenseitigen Stirnrand des Flansches anliegen. Die Federzungen können aus der Erstreckungsebene des Federblechs ausgebogen sein. Die Federvorspannung, mit der die Federzungen am Stirnrand des Flansches anliegen, kann vom Haltekragen des Kontaktträgers ausgeübt werden. Letzterer beaufschlagt den Randabschnitt der Stanzöffnung und presst somit die vorgebogenen Federzungen gegen den Randabschnitt des Kontaktträgers. Es sind bevorzugt zwei oder mehrere derartiger Stanzöffnungen vorgesehen, so dass mit dem Kontaktträger benachbart angeordnete Flansche miteinander verbunden sind. Die Verbindung mit dem Ableiter erfolgt ebenfalls bevorzugt über Federzungen, die vom Rand einer weiteren Stanzöffnung abragen. Der Ableiter kann ein im Gehäuse steckender Zapfen sein. Der Zapfen kann ein Innengewinde aufweisen, in welches eine Verbindungsschraube eingeschraubt werden kann, mit der ein äußeres Aluminiumgehäuse mit dem aus Kunststoff bestehenden Einbaugehäuse verbunden sein, welches die Steckerbuchsen trägt. Der Zapfen kann von der Gehäuseinnenseite in einen hülsenförmigen Abschnitt des Gehäuses eingepresst sein. Dies erfolgt bevorzugt im Heatsert-Verfahren. Der Ableiter besitzt darüber hinaus einen Fortsatz, der mit einer Masse-Leiterbahn einer Platine lötverbunden ist. Auch der Flansch kann in einen hülsenförmigen Abschnitt des Gehäuses einpresst sein. Auch hier wird das Heatsert-Verfahren verwendet. Ableiter bzw.

Die kleine Stanzöffnung 25 wird über einen konischen Kontaktabschnitt 26 des Zapfens 14 gestülpt.The spring plate 8 is inserted before the Klipsmontage the contact carrier 6 from the inside of the housing, wherein the spring tongues 11 on the end edge 12 of the flange 5 fitting. The small punched opening 25 is slipped over a conical contact portion 26 of the pin 14.

Anschließend werden die Kontaktträger 6 zweier benachbarter Steckerbuchsen 3 in die jeweiligen Flansche 5 eingesteckt, bis die Raststufen 21 mit den Stufen 22 verrasten. Das rückwärtige Ende des Kontaktträgers 6 bildet einen ringförmigen Kragen 15 aus. Der Kragen 15 bildet einen Halteabschnitt aus, der im montierten Zustand auf dem Rand der Stanzöffnung 24 aufliegt. Bei der Zuordnung des Kontaktträgers 6 zum Flansch 5 werden die Federzungen 11 zufolge ihrer Ausbiegung vorgespannt. Sie liegen dann federvorgespannt auf dem gehäuseinnenseitigen Stirnrand 12 des Flansches 5 an und bildet jeweils eine flächige Leitverbindung zum Flansch 5. Die Federzungen 13 bilden ebenfalls eine flächige Leitverbindung zum konischen Abschnitt 26 des Zapfens 14. Die in die Gewindeöffnung 14' eingeschraubte Gewindeschraube 17 bildet mit ihrem Kopf eine elektrische Leitverbindung zum Gehäuse 1 und mit ihrem Kontaktabschnitt 14" eine elektrische Leitverbindung zur Platine 16. Zufolge dieser Ausgestaltung können Hochspannungsentladungen über den Flansch 5 sicher abgeleitet werden.Subsequently, the contact carrier 6 of two adjacent sockets 3 are inserted into the respective flanges 5 until the latching steps 21 engage with the steps 22. The rear end of the contact carrier 6 forms an annular collar 15. The collar 15 forms a holding portion, which rests in the mounted state on the edge of the punch opening 24. In the assignment of the contact carrier 6 to the flange 5, the spring tongues 11 are biased according to their deflection. The spring tongues 13 also form a flat Leitverbindung to the conical portion 26 of the pin 14. The screwed into the threaded opening 14 'threaded screw 17 forms with its head an electrical lead to the housing 1 and with its contact portion 14 "an electrical lead to the board 16. According to this embodiment, high-voltage discharges can be safely dissipated via the flange 5.

Bei dem in den Figuren 8 und 9 dargestellten zweiten Ausführungsbeispiel wird der Leitkörper von einer Drahtfeder 9 ausgebildet. Sie besteht aus einer Drahtwendel 9" und hiervon abragenden Schenkeln 9'.In the in the FIGS. 8 and 9 illustrated second embodiment, the guide body is formed by a wire spring 9. It consists of a wire coil 9 "and protruding legs 9 'thereof.

Während die Einleitabschnitte des Federblatts 8 von den Federzungen 11 ausgebildet werden, werden die Einleitabschnitte der Drahtfeder 9 von Schenkeln 9' ausgebildet. Die Schenkel 9' können Abwinklungen aufweisen, die in federnde Anlage jeweils in einer Umfangsnut des gehäuseinnenseitigen Flanschabschnitts 12 einliegen. Der wendelgangförmige Abschnitt 9" der Feder 9 umschlingt einen zylindrischen oder konischen Abschnitt 26 des bereits bei der Erläuterung des ersten Ausführungsbeispiels erwähnten Zapfens 14 in berührender Anlage. Auch hierdurch ist eine Hochspannungsableitung vom Flansch 5 auf den Zapfen 14 bzw. das Gehäuse 1 oder die Platine 16 gewährleistet.While the lead-in portions of the spring sheet 8 are formed by the spring tongues 11, the lead-in portions of the wire spring 9 are formed by legs 9 '. The legs 9 'may have bends, which einliegen in resilient engagement in each case in a circumferential groove of the housing-side flange portion 12. The helical portion 9 "of the spring 9 wraps around a cylindrical or conical portion 26 of the spigot 14 already mentioned in the explanation of the first embodiment, which also causes high voltage dissipation from the flange 5 to the spigot 14 or the housing 1 or the board 16 guaranteed.
