Description

Eine Kabelklemme gemäss Oberbegriff des Anspruchs 1 ist aus der GB-A-889 713 bekannt. An einem Gehäuse sind zwei Klemmteile in zwei senkrecht zueinander stehenden Richtungen verschiebbar geführt. Die beiden Teile sind durch parallel zur Verschiebungsrichtung des einen Teils angeordnete Schrauben miteinander verbunden. Durch Anziehen der Schrauben kann ein Kabel zwischen den Teilen festgeklemmt werden. Durch Vertauschen der beiden Teile ist es möglich, das Kabel in zwei wählbaren Richtungen aus dem Gehäuse austreten zu lassen. Allerdings hat die Verschiebbarkeit beider Teile zur Folge, dass bei Zug am Kabel die Schrauben auf Biegung beansprucht werden. Damit und durch das unvermeidliche Spiel der Schrauben in ihren Bohrungen ist eine starre Fixierung des Kabels nicht gewährleistet.A cable clamp according to the preamble of claim 1 is known from GB-A-889 713. On a housing, two clamping parts are slidably guided in two directions perpendicular to each other. The two parts are connected to one another by screws arranged parallel to the direction of displacement of the one part. A cable can be clamped between the parts by tightening the screws. By swapping the two parts, it is possible to let the cable emerge from the housing in two selectable directions. However, the displaceability of both parts means that the screws are subjected to bending when the cable is pulled. This and the inevitable play of the screws in their holes does not guarantee a rigid fixation of the cable.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Kabelklemme mit wählbaren Kabelaustrittsrichtungen derart auszubilden, dass eine starre Fixierung des Kabels und eine Entlastung der Schrauben von Biegebeanspruchungen ermöglicht wird.The present invention is based on the object of designing a cable clamp with selectable cable exit directions in such a way that rigid fixing of the cable and relief of the screws from bending loads is made possible.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Durch die erfindungsgemäße Ausbildung wird erzielt, dass alle vom eingeklemmten Kabel quer zur Richtung der Schrauben auf das bewegliche Klemmteil ausgeübten Kräfte direkt vom Träger des festen Klemmenteils aufgenommen werden, so dass die Klemmschrauben nur noch in ihrer Längsrichtung beansprucht sind.The configuration according to the invention ensures that all the forces exerted by the clamped cable transversely to the direction of the screws on the movable clamping part are absorbed directly by the carrier of the fixed clamping part, so that the clamping screws are only stressed in their longitudinal direction.

Die Erfindung bezieht sich ferner auf einen Kabelverbinder mit einer erfindungsgemäßen Kabelklemme und mit einer Abdeckhaube, an welcher die Kabelklemme angeordnet ist. Vorzugsweise hat die Kabelklemme als Träger ein hohles Einsatzstück, welches in die Abdeckhaube eingesetzt ist.The invention further relates to a cable connector with a cable clamp according to the invention and with a cover on which the cable clamp is arranged. Preferably, the cable clamp has a hollow insert as a carrier, which is inserted into the cover.

Ausführungsbeispiele des Erfindungsgegenstandes werden nachstehend anhand der Zeichnungen erläutert. Es zeigen:

  • Fig. 1 eine Seitenansicht einer Kabelklemme mit einem Einsatzstück für eine Abdeckhaube eines Kabelverbinders,
  • Fig. 2 eine Innenansicht des Kabelklemmen-Einsatzstückes gemäß dem Pfeil in Fig. 1,
  • Fig. 3 eine Unteransicht des-Kabelklemmen-Einsatzstückes gemäß dem Pfeil 111 in Fig. 1,
  • Fig.'4 eine Seitenansicht der Abdeckhaube des Kabelverbinders mit eingesetzter Kabelklemme gemäß den Fig. 1 bis 3, und
  • Fig. 5 eine Seitenansicht der Abdeckhaube der Fig. 4 mit einem ausserhalb dieser dargestellten Kabelklemme mit einem Einsatzstück in einer weiteren Ausführungsform.
Exemplary embodiments of the subject matter of the invention are explained below with reference to the drawings. Show it:
  • 1 is a side view of a cable clamp with an insert for a cover of a cable connector,
  • 2 is an inside view of the cable clamp insert according to the arrow in FIG. 1,
  • 3 is a bottom view of the cable clamp insert according to arrow 111 in FIG. 1,
  • Fig. 4 is a side view of the cover of the cable connector with inserted cable clamp according to FIGS. 1 to 3, and
  • Fig. 5 is a side view of the cover of Fig. 4 with a cable clamp shown outside with an insert in a further embodiment.

Die in den Fig. 1 bis 3 dargestellte Kabelklemmehat ein Einsatzstück 1, das - wie nachstehend anhand der Fig. 4 noch erläutert - dazu vorgesehen ist, in die Abdeckhaube eines Kabelverbinders eingesetzt zu werden, um eine Zugentlastung des an den Kabelverbinder angeschlossenen Kabels zu bewirken. Das Einsatzstück 1 weist im allgemeinen die Form eines längs einer Diagonalfläche getrennten Hohlkubus auf. Das Einsatzstück 1 hat zwei dreieckige Seitenwände 2 und eine diese verbindende obere Wand 3. Die weitere, zu den Seitenwänden 2 und zur oberen Wand 3 senkrechte Seite ist im wesentlichen offen und mit einer Kabelklemmvorrichtung 4 versehen. Die diagonalen Kanten der Seitenwände 2 sind mit je einer Längslasche 5 versehen, die eine Längsöffnung 6 hat und die dazu dient, das Einsatzstück 1 in der Abdeckhaube des Kabelverbinders festzuhalten, wie dies anhand der Fig. 4 noch beschrieben wird.The cable clamp shown in FIGS. 1 to 3 has an insert 1 which, as will be explained below with reference to FIG. 4, is intended to be inserted into the cover of a cable connector in order to relieve the strain on the cable connected to the cable connector . The insert 1 generally has the shape of a hollow cube separated along a diagonal surface. The insert 1 has two triangular side walls 2 and an upper wall 3 connecting them. The further side perpendicular to the side walls 2 and the upper wall 3 is essentially open and provided with a cable clamping device 4. The diagonal edges of the side walls 2 are each provided with a longitudinal tab 5, which has a longitudinal opening 6 and which serves to hold the insert 1 in the cover of the cable connector, as will be described with reference to FIG. 4.

Die an der offenen Seitenfläche des Einsatzstückes 1 angeordnete Kabelklemmvorrichtung 4 besteht aus einem festen Klemmenteil 7, welches als am halbkubusförmigen Körper des als Träger für das feste Klemmenteil 7 vorgesehenen Einsatzstückes 1 angeformte Rippe ausgebildet ist, ferner aus einem beweglichen Klemmenteil 8, welches als am Körper des Einsatzstückes 1 geführtes Gleitstück ausgebildet ist, und aus zwei Klemmschrauben 9, welche im festen Klemmenteil 7 drehbar gelagert sind und in entsprechende Gewindebohrungen des beweglichen Klemmenteils 8 geschraubt sind. Das feste Klemmenteil 7, dessen vorstehender, rippenförmiger Abschnitt eine sich in das Innere des Einsatzstückes erstreckende Verlängerung 10 hat, und das bewegliche Klemmenteil 8 weisen beide einen runden Abschnitt 11 auf, der dazu dient, das durch die Abdeckhaube geführte Kabel beim Anziehen der Schrauben 9 zu umgreifen.The arranged on the open side surface of the insert 1, the cable clamping device 4 consists of a fixed clamping part 7, which is formed as a rib formed on the semi-cube-shaped body of the insert 1 provided as a support for the fixed clamping part 7, and also of a movable clamping part 8, which as on the body of the insert 1 guided slider is formed, and from two clamping screws 9, which are rotatably mounted in the fixed clamping part 7 and are screwed into corresponding threaded bores of the movable clamping part 8. The fixed clamp part 7, the projecting, rib-shaped section of which has an extension 10 which extends into the interior of the insert, and the movable clamp part 8 both have a round section 11, which serves for the cable which is guided through the cover hood when the screws 9 are tightened to embrace.

Wie am besten aus den Fig. 2 und 3 ersichtlich, ist das bewegliche, als Gleitstück ausgebildete Klemmenteil 8 mit dem Körper des Einsatzstückes 1 über eine Schlittenführung 12 verbunden. Die Schlittenführung 12 umfasst einerseits zwei an je einer Seitenwand 2 angeformte, sich nach innen erstreckende Längsrippen 13 und zwei entsprechenden, an je einer Schmalseite des beweglichen Klemmenteils 8 ausgebildeten Nuten 14. Somit ist die Bewegungsrichtung des Klemmenteils 8 auf die Richtung der Schrauben 9 eingeschränkt, wie dies in den Fig. 1 und 2 durch einen Doppelpfeil 15 angedeutet ist.As can best be seen from FIGS. 2 and 3, the movable clamping part 8, which is designed as a slide, is connected to the body of the insert 1 via a slide guide 12. The slide guide 12 comprises, on the one hand, two longitudinal ribs 13 which are formed on a side wall 2 and extend inwards and two corresponding grooves 14 which are formed on a narrow side of the movable clamping part 8. The direction of movement of the clamping part 8 is thus restricted to the direction of the screws 9, as indicated in FIGS. 1 and 2 by a double arrow 15.

In Fig. 4 ist eine Abdeckhaube 16 für einen Kabelverbinder dargestellt, welche mit der Kabelklemme gemäß den Fig. 1 bis 3 versehen ist. Die im wesentlichen quaderförmige Abdeckhaube 16 hat eine offene Seite 17 zur Aufnahme eines mit Kontaktelementen versehenen Sockels des Kabelverbinders und eine schräg abgeschnittene, offene Seite 18 zur Aufnahme des Einsatzstückes 1, wobei die übrigen Seiten der Abdeckhaube 16 geschlossen sind. Die eine, in Ansicht dargestellte Seitenwand ist durch einen Deckel 19 gebildet, welcher mittels Schrauben 20 befestigt ist. Die Innenseite des Deckels 19 sowie die Innenseite der gegenüberliegenden Seitenwand sind mit je einer angedeuteten Rippe 21 versehen, welche beide in die Öffnung 6 (Fig. 1) des Einsatzstückes 1 passen. Somit wird das Einsatzstück 1 in der Abdeckhaube 16 bei aufgeschraubtem Deckel 19 durch die in die Öffnungen 6 des Einsatzstückes 1 greifenden Rippen 21 des Deckels 19 und der gegenüberliegenden Seitenwand festgehalten.FIG. 4 shows a cover 16 for a cable connector, which is provided with the cable clamp according to FIGS. 1 to 3. The essentially cuboid cover 16 has an open side 17 for receiving a base of the cable connector provided with contact elements and an obliquely cut open side 18 for receiving the insert 1, the other sides of the cover 16 being closed. The one side wall shown in view is formed by a cover 19 which is fastened by means of screws 20. The inside of the cover 19 and the inside of the opposite side wall are each provided with an indicated rib 21, both of which fit into the opening 6 (FIG. 1) of the insert 1. Thus, the insert 1 is held in the cover 16 when the cover 19 is screwed on by the ribs 21 of the cover 19 and the opposite side wall which extend into the openings 6 of the insert 1.

Während in der Darstellung der Fig. 4 der durch die Kabelklemmvorrichtung 4 erfolgende Austritt des Kabels aus der Abdeckhaube 16 seitlich ist, kann durch um 180° gedrehtes Einsetzen des Einsatzstückes 1 auch ein Kabelaustritt nach oben erzielt werden.While in the illustration in FIG. 4 the exit of the cable from the cover 16 through the cable clamping device 4 is at the side, inserting the insert 1 rotated through 180 ° also enables a cable exit upwards.

Bei der vorliegenden Kabelklemme ist durch die Schlittenführung 12 jede durch einen entsprechenden Kabelzug in einer von der Längsrichtung der Schrauben 9 abweichenden Richtung mechanische Krafteinwirkung auf das bewegliche Klemmenteil 8 verunmöglicht. Dadurch ergibt sich nicht nur eine vollständige Zugentlastung des Kabels, sondern auch eine wesentliche Erleichterung des Einspannens des Kabels zwischen dem festen Klemmenteil 7 und dem beweglichen Klemmenteil 8, weil die Schrauben 9 nur noch auf Zug beansprucht sind, nicht jedoch Biegungskräften ausgesetzt sind.In the present cable clamp, the slide guide 12 prevents any mechanical force acting on the movable clamp part 8 due to a corresponding cable pull in a direction deviating from the longitudinal direction of the screws 9. This not only results in a complete strain relief for the cable, but also makes it much easier to clamp the cable between the fixed clamp part 7 and the movable clamp part 8, because the screws 9 are only subjected to tension, but are not subjected to bending forces.

In Fig. 5 ist ein Ausführungsbeispiel eines als Träger vorgesehenen Kabelklemmen-Einsatzstückes 22 dargestellt, bei welchem die Seitenwände 2 und die obere Wand 3 des Einsatzstückes 1 der Fig. 1 bis 3 fehlen und bei welchem sich die Längslaschen 5 mit den Öffnungen 6 parallel zu den Schrauben 9 der Kabelklemme 4 erstrecken, die im übrigen gleich ausgebildet ist wie diejenige der Fig. 1 bis 3. Das Kabelklemmen-Einsatzstück 22 wird wie in Fig. 4 bei abgenommenem Deckel 19 in die offene Seite 18 der Abdeckschraube 16 eingesetzt und nach dem Aufschrauben des Deckels 19 durch die Rippen 21 in der Abdeckhaube 16 festgehalten. Mit der das Kabelklemmen-Einsatzstück 22 der Fig. 5 aufweisenden Kabelklemme wird die beschriebene Zugentlastung des Kabels bei einem Kabelaustritt unter 45° aus der Abdeckhaube des Kabelverbinders erzielt.5 shows an embodiment of a cable clamp insert 22 provided as a carrier, in which the side walls 2 and the upper wall 3 of the insert 1 of FIGS. 1 to 3 are missing and in which the longitudinal tabs 5 with the openings 6 parallel to one another extend the screws 9 of the cable clamp 4, which is otherwise of the same design as that of FIGS. 1 to 3. The cable clamp insert 22 is inserted into the open side 18 of the cover screw 16 as in FIG. 4 with the cover 19 removed and after Screwing on the cover 19 held in place by the ribs 21 in the cover 16. With the cable clamp insert 22 of FIG. 5, the described strain relief of the cable is achieved with a cable outlet at 45 ° from the cover of the cable connector.

Die dargestellte und beschriebene Ausbildung der Kabelklemme mit einem als Träger vorgesehenen Einsatzstück für eine Abdeckhaube eines Kabelverbinders ist bloss eine von zahlreichen möglichen Anwendungs-und Ausführungsmöglichkeiten der erfindungsgemäßen Kabelklemme. Diese kann als Träger des festen Klemmenteils auch andere Apparate, Geräte- und Vorrichtungsteile aufweisen. Ferner kann die Gleitführung des beweglichen Klemmenteils am Träger des festen Klemmenteils, deren Gleitrichtung mit der Längsrichtung der Klemmschrauben der Kabelklemme übereinstimmt, auch in anderer Weise als gemäß Fig. 1 bis 3 ausgebildet sein, beispielsweise mittels einzelner Vorsprünge statt der Längsrippen 13, als Schwalbenschwanzführung, in umgekehrter Anordnung bezüglich Rippen und Nuten usw.The illustrated and described embodiment of the cable clamp with an insert provided as a support for a cover of a cable connector is just one of numerous possible applications and embodiments of the cable clamp according to the invention. This can also have other apparatus, device and device parts as a carrier of the fixed clamp part. Furthermore, the sliding guide of the movable clamping part on the carrier of the fixed clamping part, the sliding direction of which corresponds to the longitudinal direction of the clamping screws of the cable clamp, can also be designed in a different way than according to FIGS. 1 to 3, for example by means of individual projections instead of the longitudinal ribs 13, as a dovetail guide, in reverse order with respect to ribs and grooves etc.
