So ist aus der DE 198 37 530 C1 eine Kabeleinführung bekannt bei der ein geschirmtes Kabel mittels eines elektrisch leitenden Gleitringes erfolgt, der mit einer elektrisch leitenden Druckschraube kontaktiert.
Dabei weist die eine Seite des Kontaktelementes zu einem im Isolierkörper integrierten Kontaktteil, während die andere Seite, mit einer Öffnung für das zu verdrillende Abschirmgeflecht des geschirmten elektrischen Kabels versehen ist sowie einem umgebogenen federnden Kontaktende, das das Abschirmgeflecht in einer im Isolierkörper vorgesehenen Ausnehmung festklemmt.
- Fig. 1
- einen Rundsteckverbinder in einer auseinandergezogenen Darstellung,
- Fig. 2a
- elektrische Verbindung des Innenleiters in einer auseinandergezogenen Darstellung,
- Fig. 2b
- einen Isolierkörper mit einem Kontaktelement um 180° gegenüber der Fig. 2a gedreht,
- Fig. 3
- eine isometrische Darstellung eines kompletten Rundsteckverbinders, und
- Fig. 4
- eine Detaildarstellung der Kontaktierung zwischen dem Kontaktelement und der Hülse.
Speziell herausgehoben und gezeigt ist das Kontaktteil 10, dessen Schneidklemme 19 am anschlussseitigen Teil 14 in eine entsprechende, schlitzförmige Aufnahme 21 eines Isolierkörpers 20 weist. (Siehe auch Fig. 2a) Auf den Isolierkörper, in dem auch Leiterführungskanäle 22 vorgesehen sind, in denen signalführende elektrische Einzelleiter 54 geführt sind, folgt ein Druck/Klemmteil 30, mit dem das elektrische Kabel 50 gegen Auszug aus dem Steckverbinder 1 gesichert ist.
Zwischen dem Isolierkörper und der Kabelverschraubung ist ein Kontaktelement 25 eingefügt, das weiter unten erklärt wird.
Darauf folgt eine metallische Schraubhülse 40 mit der der Steckverbinder nach dem Aufschrauben auf das Trägergehäuse 3 zusammengehalten wird sowie eine Schirmhülse 45, die bei entsprechender Positionierung den elektrischen Kontakt von der Schraubhülse 40 über den isolierenden Trägerkörper 3 zum metallischen Steckteil 2 weiterleitet.
Das steckseitige Teil weist einen Steckstift 15 zur Kontaktierung mit einem Gegenstecker und eine Buchse 16 auf, in die ein stiftförmiger Ansatz 17 des anschlussseitigen Teiles 14 einfügbar ist. Das Teil 14 wird mittels einer Arretierungsfeder 18 im Isolierkörper 20 festgehalten. Die zweite Seite des anschlussseitigen Teiles ist als Schneidklemme 19 ausgebildet, in die das Kontaktelement 25 mit einer dazu vorgesehenen Abwinklung 26 eingedrückt wird.
Das Kontaktelement 25 ist als U-förmiges flaches Biegeteil mit einer asymmetrisch angeordneten runden Öffnung 29 im mittleren Bereich 27, einer um 90° abgebogenen Abwinklung 26 und einem auf mindestens 35° zum mittleren Bereich umgebogenen federnden Ende 28 ausgebildet.
Bei der Montage wird das Kontaktelement auf der Abwinklungsseite 26 in der Aufnahme 21' mit der Schneidklemme 19 kontaktiert und auf der anderen Seite mit dem umgebogenen federnden Ende 28 in der axial angeordneten Ausnehmung 23 im Isolierkörper 30 eingeklemmt.
Weiterhin ist im Kragen eine weitere Ausnehmung 36 über die gesamte Höhe des Kragens vorgesehen, in die das Kontaktelement 25 mit dem umgebogenen, federnden Ende 28 hineinreicht.
Die Kabelschirmung 52 wird vor der Montage des Steckverbinders verdrillt und durch die Öffnung 29 im Kontaktelement gefädelt.
Anschließend werden die Einzelleiter 54 in die Leiterführungskanäle 22 des Isolierteiles eingeschoben und das Druck/Klemmteil 30 mit dem Kontaktelement 25 auf den Isolierkörper 20 aufgesetzt.
Dabei wird die verdrillte Kabelschirmung in die axial an der Außenwandung des Isolierkörpers eingeformte Ausnehmung 23 eingelegt, wobei das umgebogene, federnde Ende 28 die verdrillte Kabelschirmung in die Ausnehmung presst.
Über den Isolierkörper hinausragende Einzelleiterenden 54 sowie Kabelschirmung werden abgeschnitten und Isolierkörper mit Kabelverschraubung in den Trägerkörper 3 geschoben. Dabei werden die in den Leiterführungskanälen geführten Einzelleiter durch die im Trägerkörper fest eingefügten (hier nicht gezeigten) Schneidklemmkontakte geschnitten und gleichzeitig eine elektrisch leitende Verbindung zu dem Kontaktteil 10 hergestellt. Anschließend wird die Schraubhülse 40 aufgeschoben und mit dem Trägerkörper 3 verschraubt. Dabei wird das umgebogene, federnde Ende 28 in eine dafür vorgesehene Nut 5 im Trägerkörper eingefügt und mit der Biegekante 28' gegen die Innenwandung 42 der Außenverschraubung gedrückt, so dass neben einer innenliegenden Abschirmung hiermit auch eine zweite elektrisch leitende Außenabschirmung über die Schraubhülse 40 erfolgt. Diese Abschirmung wird jedoch erst aktiv, wenn die Hülse 45 über die Schraubhülse 40 und das Steckteil 2 gezogen wird, so dass der isolierende Teil des Trägerkörpers 3 überbrückt ist, wie in der Fig. 3 bei dem komplett dargestellten Steckverbinder 1 gezeigt.
Auf der anderen Seite des Kontaktelentes 25 wird mit der Abwinklung 26, die in der Aufnahme 21' eingefügt ist, die Schneidklemme 19 kontaktiert, die in der Aufnahme 21 positioniert ist.
