Description

Beschreibungdescription

Die Erfindung betrifft eine Vorrichtung zur Verklemmung eines mit einem Steckverbinder verbundenen elektrischen Kabels, bestehend aus einem Steckverbindergehäuse, mit einer für das Kabel angeformten Aufnahmehülse, welche mit einem Gewinde und wenigstens einem Klemmelement versehen ist.The invention relates to a device for clamping an electrical cable connected to a connector, consisting of a connector housing, with a formed for the cable receiving sleeve, which is provided with a thread and at least one clamping element.

Eine derartige Vorrichtung wird benötigt, um ein an Kontaktelementen eines Steckverbinders angeschlossenes Kabel zu verklemmen und im Steckverbindergehäuse zu fixieren. Auftretende Zugkräfte am Kabel des Steckverbinders sollen aufgenommen und die Kontaktanschlüsse des Steckverbinders, an denen das Kabel kontaktiert ist, entlastet werden.Such a device is required to clamp a connected to contact elements of a connector cable and to fix in the connector housing. Occurring tensile forces on the cable of the connector should be added and the contact terminals of the connector to which the cable is contacted, be relieved.

Stand der TechnikState of the art

Im Stand der Technik sind bereits einige Lösungen zur Befestigung von Kabeln an Steckverbindern bekannt.In the prior art, some solutions for attaching cables to connectors are already known.

Aus der US 6,284,973 ist eine Zugentlastung für ein Kabel bekannt, die aus einer Basis mit einer schlauchartigen Verlängerung besteht. Die schlauchartige Verlängerung besitzt eine Vielzahl von biegsamen Armen die sich durch Aufschrauben einer Mutter, die im Inneren einen konischen Bereich besitzt, verengen lassen.From the US 6,284,973 a strain relief for a cable is known, which consists of a base with a hose-like extension. The tubular extension has a variety of flexible arms which can be narrowed by screwing a nut, which has a conical area inside.

Eine auch oft genutzte Variante zur Zugentlastung ist das Einsetzen einer Kronenfeder zur Verklemmung des Kabels. Hierbei sitze eine Kronenfeder auf dem Kabel, die durch Eindrücken mittels einer Druckschraube in eine konische Hülle am Steckverbinderende zusammengepresst wird und das Kabel so im Steckverbinder hält.An often used variant for strain relief is the insertion of a crown spring to clamp the cable. In this case, a crown spring sitting on the cable, by pressing in with a pressure screw in a conical sleeve is pressed together at the connector end and the cable holds in the connector.

Nachteilig wirkt sich dabei aus, dass bei den bekannten Klemmsystemen die Kabelklemmung nur geringe Zugkräfte aufnehmen kann, da die Klemmarme in Richtung der Zugkraft weisen und somit keine größeren Klemmkräfte auf das Kabel ausüben können. In zweit genannter Variante wirkt sich nachteilig aus, dass bei der Verschraubung der Zugentlastung ein Verdrehen der Kronenfeder und damit des Kabels unvermeidbar ist, wodurch die Adern des Kabels verletzt werden können.The disadvantage of this is that in the known clamping systems, the cable clamping can absorb only low tensile forces, since the clamping arms point in the direction of the tensile force and thus can not exert greater clamping forces on the cable. In the second variant mentioned adversely affects that when screwing the strain relief twisting of the crown spring and thus the cable is unavoidable, causing the wires of the cable can be injured.

Aufgabenstellungtask

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Verklemmung eines Kabels an einem Steckverbinder anzugeben, die Kabel mit einer großen Durchmesservariabilität aufnehmen kann, hohen Zugkräften auf das Kabel entgegenwirkt und ein Verdrehen des Kabels verhindert.The invention is therefore an object of the invention to provide a device for jamming a cable to a connector that can accommodate cables with a large diameter variability, counteracts high tensile forces on the cable and prevents twisting of the cable.

Diese Aufgabe wird dadurch gelöst, dass das Klemmelement in einer Aussparung längs der Aufnahmehülse angeordnet ist, dass das Klemmelement dreiseitig freigestellt ist, mit einem freien, in Steckrichtung zeigenden Ende, dass das Klemmelement an seiner, radial nach außen zeigenden Fläche eine Verdickung aufweist, die zum befestigten Ende des Klemmelementes eine abflachende, schräge Fläche bildet, und dass durch Aufschrauben einer Druckschraube auf die Aufnahmehülse das Klemmelement radial nach innen gedrückt wird und das Kabel verklemmt.This object is achieved in that the clamping element is arranged in a recess along the receiving sleeve, that the clamping element is free on three sides, with a free, pointing in the insertion direction end, that the clamping element on its, radially outwardly facing surface has a thickening, the to the fixed end of the clamping element forms a flattening, inclined surface, and that by screwing a pressure screw on the receiving sleeve, the clamping element is pressed radially inward and jammed the cable.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2-6 angegeben.Advantageous embodiments of the invention are specified in claims 2-6.

Bei der Erfindung handelt es sich um eine Vorrichtung die benötigt wird, um ein Kabel, das an einen Steckverbinder angeschlossen ist, an diesem zu verklemmen und dadurch hohe, auf das Kabel wirkende, Zugkräfte aufzunehmen und die Anschlüsse im Steckverbinder zu entlasten.In the invention, it is a device which is required to clamp a cable which is connected to a connector, and thereby to absorb high, acting on the cable, tensile forces and to relieve the terminals in the connector.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass ein Steckverbindergehäuse an der, der Steckseite abgewandten Rückseite mit einer Aufnahmehülse versehen ist, in die ein anzuschließendes Kabel durchgeführt und darin mittels vorzugsweise mehreren Klemmelementen verklemmt wird. Auf die Aufnahmehülse ist eine Druckschraube zur Betätigung der Klemmelemente aufschraubbar.The advantages achieved by the invention are in particular that a connector housing is provided on the side facing away from the plug side back with a receiving sleeve, in which a cable to be connected carried out and clamped therein by means of preferably a plurality of clamping elements. On the receiving sleeve, a pressure screw for actuating the clamping elements can be screwed.

Die Aufnahmehülse ist im Wesentlichen als zylindrische Anformung am Steckverbindergehäuse angebracht. Die Außenseite ist mit einem Gewinde zum Aufschrauben der Druckschraube versehen. Über den Umfang der Aufnahmehülse verteilt sind Aussparungen, in Form von Durchbrüchen, vorgesehen, die jeweils die Klemmelemente aufnehmen.The receiving sleeve is mounted substantially as a cylindrical Anformung the connector housing. The outside is provided with a thread for screwing on the pressure screw. Distributed over the circumference of the receiving sleeve are recesses, provided in the form of apertures, which each receive the clamping elements.

Die Klemmelemente sind als dreiseitig freigestellte Anformungen in den Aussparungen angeformt, wobei das der Rückseite des Steckverbindergehäuses zugewandte Ende von innen in der Aussparung angeformt ist.The clamping elements are integrally formed in the recesses as three-sided exempt formations, wherein the rear side of the connector housing facing the end is formed from the inside in the recess.

Die Klemmelemente verfügen an ihrer radial nach außen zeigenden Seite über eine Verdickung, die jeweils über den Gewindeaußendurchmesser der Aufnahmehülse hinweg ragen. Die Verdickung flacht zum rückseitigen Ende der Klemmelemente ab, wodurch eine schräge Fläche gebildet wird, die an ihrem flachen Ende in die Verbindung zur Aufnahmehülse übergeht.The clamping elements have on their radially outwardly facing side over a thickening, which protrude beyond the outer thread diameter of the receiving sleeve. The thickening flattened to the rear end of the clamping elements, whereby an inclined surface is formed, which merges at its flat end in the connection to the receiving sleeve.

In einer bevorzugten Ausbildungsform sind in der Aufnahmehülse vier Aussparungen mit jeweils einem Klemmelement vorgesehen.In a preferred embodiment, four recesses, each with a clamping element are provided in the receiving sleeve.

Die Druckschraube ist im Wesentlichen ein als Hohlzylinder ausgeformtes Teil, das mit einem Innengewinde versehen ist, um auf die Aufnahmehülse aufgeschraubt zu werden. An der Rückseite der Druckschraube ist eine (Öffnung vorgesehen, durch die das anzuschließende Kabel geführt wird.The pressure screw is essentially a part formed as a hollow cylinder, which is provided with an internal thread to be screwed onto the receiving sleeve. At the back of the pressure screw is provided an opening through which the cable to be connected is guided.

In einer zweckmäßigen Ausbildungsform verfügt die Druckschraube an ihrer Außenfläche über An- oder Ausformungen, die ein besseres Greifen der Schraube oder Ansetzten von Werkzeug ermöglichen.In an expedient embodiment, the pressure screw has on its outer surface on or formations that allow a better gripping the screw or attaching tool.

Erfindungsgemäß drückt beim Aufschrauben der Druckschraube auf die Aufnahmehülse, die in Steckrichtung zeigende, radiale, innere Kante der Druckschraube auf die schräge Fläche der Klemmelemente. Die hierbei auftretende Kraft führt zu einer Bewegung des Klemmelementes in Richtung des Kabels, wodurch sich das freie Ende radial nach innen um das befestigte Ende bewegt und auf das sich in der Aufnahmehülse befindliche Kabel einwirkt.According to the invention presses when screwing the pressure screw on the receiving sleeve, pointing in the insertion direction, radial, inner edge of the pressure screw on the inclined surface of the clamping elements. The force occurring in this case leads to a movement of the clamping element in the direction of the cable, whereby the free end moves radially inwardly around the fixed end and acts on the cable located in the receiving sleeve.

In einer weiteren zweckmäßigen Ausbildungsform sind die Klemmelemente am steckseitigen, inneren Ende mit zusätzlichen Mitteln versehen, die eine bessere Haftung des Klemmelementes am Kabel ermöglichen.In a further expedient embodiment, the clamping elements are provided on the plug side, inner end with additional means that allow better adhesion of the clamping element on the cable.

Eine vorteilhafte Weiterbildung sieht in der Klemmvorrichtung zusätzlich eine Dichtung vor, um das Eindringen von Wasser und Schmutz zu verhindern.An advantageous development provides in the clamping device in addition to a seal to prevent the ingress of water and dirt.

Eine weitere vorteilhafte Weiterbildung ist vorgesehen, bei der innerhalb der Aufnahmehülse eine Innenhülse eingeformt ist, auf die ein schlauchähnlicher Hohlkörper aufgeschoben und fixiert werden kann.A further advantageous embodiment is provided, in which an inner sleeve is formed within the receiving sleeve, on which a hose-like hollow body can be pushed and fixed.

An embodiment of the invention is illustrated in the drawing and will be explained in more detail below. Show it:
  • Fig. 1 a connector housing in a spatial view with partly screwed pressure screw,
  • Fig. 2 a connector housing in a spatial view,
  • Fig. 3 a connector housing in the plan view of the receiving sleeve,
  • Fig. 4 a connector housing with pressure screw in the elongated section, and
  • Fig. 5 a connector housing with an inner sleeve molded in the receiving sleeve.

In der Fig.1 ist ein aus räumlicher Ansicht gezeigtes Steckverbindergehäuse 1 dargestellt, auf welches eine Druckschraube 5 teilweise aufgeschraubt ist. Im hier links abgebildeten Teil des Steckverbindergehäuses 1 ist ein Kontaktbereich 3 zu erkennen, der zur Aufnahme von Kontaktelementen dient. Im hier rechts abgebildeten Bereich des Steckverbindergehäuses 1 schließt sich an den Kontaktbereich 3 der Anschlussbereich an, welcher durch eine angeformte Aufnahmehülse 10 gebildet wird.In the Fig.1 is a connector housing 1 shown from a spatial view shown, on which a pressure screw 5 is partially screwed. In the part of the connector housing 1 shown on the left here, a contact region 3 can be seen, which serves to receive contact elements. In the region of the connector housing 1 depicted on the right here, the connection region adjoins the contact region 3, which is formed by an integrally formed receiving sleeve 10.

Die Aufnahmehülse 10 dient zur Aufnahme eines in das Steckverbindergehäuse 1 einzuführenden elektrischen Kabels 2, das mit den Kontaktelementen verbunden wird. Die zylindrisch ausgeformte Aufnahmehülse 10 ist mit einem Gewinde 11 versehen, auf das sich die Druckschraube 5 aufschrauben lässt. In der Aufnahmehülse 10 sind über den Umfang verteilt Aussparungen 13 vorgesehen, in denen jeweils ein Klemmelement 20 angeordnet ist. Dabei ragen die Klemmelemente 20 teilweise radial über den Außendurchmesser 12 des Gewindes 11 heraus, sodass bei weiterem Aufschrauben der Druckschraube 5, diese eine Kraft auf die Klemmelemente 20 ausübt und diese nach innen drücken.The receiving sleeve 10 serves to receive an inserted into the connector housing 1 electrical cable 2, which is connected to the contact elements. The cylindrically shaped receiving sleeve 10 is provided with a thread 11, on which the pressure screw 5 can be screwed. In the receiving sleeve 10 distributed over the circumference recesses 13 are provided, in each of which a clamping element 20 is arranged. In this case, the clamping elements 20 protrude partially radially beyond the outer diameter 12 of the thread 11, so that upon further screwing the pressure screw 5, this exerts a force on the clamping elements 20 and press them inwards.

In Fig. 2 ist ein alleinstehendes Steckverbindergehäuse 1 in räumlicher Ansicht dargestellt, mit Blick auf die Aufnahmehülse 10. Zu erkennen sind hier vier Aussparungen 13, die über den Umfang der Aufnahmehülse 10 gleichmäßig verteilt sind. In jeder Aussparung 13 ist ein Klemmelement 20 vorgesehen, das dreiseitig freigestellt und gegen die Steckrichtung in der Aussparung 13 befestigt ist. Die Klemmelemente 20 weisen radial nach außen und zeigend eine Verdickung 23 auf, die über den Aussendruchmesser 12 des Gewindes 11 ragen. Zum befestigten Ende 22 hin flacht die Verdickung 23 ab und bildet so eine schräge Fläche 24 auf die beim Aufschrauben der Druckschraube 5 diese einwirkt.In Fig. 2 is a standalone connector housing 1 shown in a three-dimensional view, with a view of the receiving sleeve 10. To recognize here are four recesses 13, which are distributed uniformly over the circumference of the receiving sleeve 10. In each recess 13, a clamping element 20 is provided, which is free on three sides and secured against the insertion direction in the recess 13. The clamping elements 20 have radially outward and pointing to a thickening 23, which protrude beyond the Außendruchmesser 12 of the thread 11. Towards the fastened end 22, the thickening 23 flattens out and thus forms an inclined surface 24 on which it acts when the pressure screw 5 is screwed on.

Die Fig. 3 zeigt ein Steckverbindergehäuse 1 in einer Draufsicht auf die Aufnahmehülse 10. Die Klemmelemente 20 ragen im hier dargestellten Ausgangszustand in den Innenbereich des Steckverbinders hinein.The Fig. 3 shows a connector housing 1 in a plan view of the receiving sleeve 10. The clamping elements 20 protrude in the initial state shown here in the interior of the connector inside.

Dabei ist auch die Schnittlinie I, II für die Fig. 4 eingefügt.It is also the section line I, II for the Fig. 4 inserted.

In der Fig. 4 ist ein Steckverbindergehäuse 1 mit Druckschraube 5 im Schnitt entlang der Längsachse dargestellt, wobei im oberen Bereich die Druckschraube 5 nur teilweise auf die Aufnahmehülse 10 aufgeschraubt ist und im unteren Bereich die Druckschraube 5 vollständig auf die Aufnahmehülse 10 aufgeschraubt ist. Zu erkennen ist, wie die Druckschraube 5 an der schrägen Fläche 24 des Klemmelementes 20 anliegt und beim Aufschrauben eine Kraft auf dieses ausübt. Bei weiterem Aufschrauben bewegt sich das freie Ende 21 des Klemmelementes 20 radial nach innen und wirkt auf das in der Aufnahmehülse 10 befindliche elektrische Kabel 2 ein.In the Fig. 4 is a connector housing 1 with pressure screw 5 shown in section along the longitudinal axis, wherein in the upper region of the pressure screw 5 is only partially screwed onto the receiving sleeve 10 and the pressure screw 5 is completely screwed onto the receiving sleeve 10 in the lower area. It can be seen how the pressure screw 5 rests against the inclined surface 24 of the clamping element 20 and exerts a force on this when screwing. Upon further screwing, the free end 21 of the clamping element 20 moves radially inwardly and acts on the electrical cable 2 located in the receiving sleeve 10.
