Definitions

  • connection devices and in particular the connection devices for cables.

    - einen oder mehrere erste Zentrierungskanten (14) (1, 2), die beim Einrasten axial in eine Kabelaustrittsöffnung des Verbinders eingesetzt werden können, wobei die Kanten in der Weise positioniert sind, dass sie, sobald sie eingesetzt sind, die Entfernung des einen Halbgehäuses von dem anderen Halbgehäuse begrenzen.
  2. Haltevorrichtung nach Anspruch 1, wobei das erste Kabelführungsorgan (4) und das zweite Kabelführungsorgan, sobald sie umschlossen sind, eine im Wesentlichen zylindrische Leitung bilden.
  3. Haltevorrichtung nach einem der vorhergehenden Ansprüche, wobei jedes Halbgehäuse (1, 2) zwei elastische Laschen (7) umfasst, die sich jeweils in einer im Wesentlichen axialen Richtung (z) erstrecken und jeweils ein Einhakende (8) tragen, das an einer komplementären Vertiefung (29) oder Höhlung, die in dem Verbinder ausgebildet ist, einrasten kann.
  4. Haltevorrichtung nach Anspruch 3, wobei die zwei Halbgehäuse (1, 2) konfiguriert sind, durch gegenseitiges Annähern der zwei Halbgehäuse längs einer ersten Richtung (x) zusammengefügt zu werden, und wobei die zwei Einrastlaschen (7) sich beiderseits des Halbgehäuses befinden und dabei längs einer zweiten Richtung (y), die zu der ersten Richtung (x) senkrecht ist, orientiert sind.
  5. Haltevorrichtung nach einem der vorhergehenden Ansprüche, die ein Umschließungsmittel (6, 40) umfasst, das wenigstens einen Ringabschnitt (6, 46) mit einer im Wesentlichen zylindrischen inneren Oberfläche (18) aufweist, und wobei in der zusammengefügten Position der Vorrichtung (3) das erste Kabelführungsorgan (4) und das zweite Kabelführungsorgan (4) eine Stirnkante (12) aufweisen, die über den Ringabschnitt axial vorsteht und in Bezug auf den Durchmesser der im Wesentlichen zylindrischen inneren Oberfläche (18) radial vorsteht.
  6. Haltevorrichtung nach den Ansprüchen 2 und 5, wobei die im Wesentlichen zylindrische Leitung eine äußere Umfangskehle (13) mit einer axialen Breite, die im Wesentlichen gleich der axialen Breite des Ringabschnitts (6, 46) ist, aufweist.
  7. Haltevorrichtung nach einem der Ansprüche 5 bis 6, wobei der Ring zwei Halbringe (16, 17) auf Polymerbasis umfasst, die an einem ihrer Enden längs eines Scharniers (19, 20) aneinander angebracht sind und an ihren jeweils anderen Enden ein Einrastende (23, 24) aufweisen, das zu einem Einrastende des anderen Halbrings komplementär ist.
  8. Haltevorrichtung nach Anspruch 7, wobei das Einrastende eines der Halbringe eine Zunge (23) aufweist, die konfiguriert ist, durch eine Öffnung (24) des Einrastendes des anderen Halbrings zu gleiten.
  9. Haltevorrichtung nach einem der Ansprüche 5 bis 6, wobei das Umschließungsmittel (40) eine erste Halbklaue (41) und eine zweite Halbklaue (42) umfasst, die jeweils die gleiche Anzahl von Ringhalbabschnitten (39a, 39b, 39c, 43a, 43b, 43c) mit zueinander parallelen Achsen aufweisen, wobei jede Halbklaue wenigstens ein Einrastorgan (44, 45) zwischen jedem Ringhalbabschnitt aufweist und ein Einrastorgan (44, 45) beiderseits der Gesamtheit von zwei Ringhalbabschnitten enthält, wobei die zwei Halbklauen konfiguriert sind, aneinander in der Weise eingerastet werden zu können, dass in jedem Ringabschnitt (46) ein erstes Kabelführungsorgan (4) des ersten Halbgehäuses (1) und ein zweites Kabelführungsorgan (4) des zweiten Halbgehäuses (2) eingeklemmt werden.
  10. Haltevorrichtung nach einem der Ansprüche 5 bis 8, wobei jeder Ringabschnitt auf einer inneren Fläche (18) des Ringabschnitts wenigstens eine Erhebung, ein Band (21) oder eine Abstützfläche aus elastomerem Material aufweist.
  11. Haltevorrichtung nach Anspruch 10, wobei jeder Ringabschnitt (1, 2) auf einer inneren Fläche (18) des Ringabschnitts wenigstens ein elastomeres Band (21) aufweist, das sich längs einer Umfangsrichtung des Ringabschnitts erstreckt.
  12. Haltevorrichtung nach Anspruch 9, wobei das elastomere Band (21) über eine Rille der inneren Oberfläche (18) des Ringabschnitts gegossen ist und einen Mittelkanal (22) aufweist, in dem die radiale Dicke in Bezug auf die maximale radiale Dicke des Bandes verringert ist.
  13. Haltevorrichtung nach einem der Ansprüche 3 bis 12, wobei die elastischen Laschen (7) mit einem Teil (33) des Halbgehäuses, der die Kabelstränge abdeckt, einteilig ausgebildet sind und wobei die elastischen Laschen (7) auf der Seite gegenüber ihrem Einrastende durch eine Ausrastzunge (11) verlängert sind, die ermöglicht, die Lasche durch Druck auf die Zunge manuell zu neigen.
  14. Anschlussanordnung, die einen Verbinder umfasst, der wenigstens einen ersten und einen zweiten Kabelstrang (10) verbinden kann, wobei der Verbinder einen Körper umfasst, in dem der erste und der zweite Kabelstrang miteinander vereinigt sind, wobei die Anordnung außerdem wenigstens eine Haltevorrichtung (3) nach einem der Ansprüche 3 bis 13 umfasst, die jederzeit an dem Verbinder eingerastet werden kann.
  15. Anschlussanordnung nach Anspruch 14, wobei die Enden der elastischen Laschen (7) in Einrastrillen (29) eingerastet werden, die zu diesem Zweck in einer äußeren Oberfläche des Verbinders ausgebildet sind, wobei sich die Rillen längs der ersten Montagerichtung (x) der Halbgehäuse erstrecken, und wobei der Verbinder auf der äußeren Oberfläche vertiefte Abschnitte (31) aufweist, die dann, wenn die beiden Halbgehäuse (1, 2) an dem Verbinder zusammengefügt sind, verhindern, dass die zwei Halbgehäuse längs der ersten Richtung in Bezug auf den Verbinder gleiten.
