Description

Die Erfindung bezieht sich auf eine Steckverbindung für elektrische Kabelsysteme mit einem Kupplungselement bzw. Steckergehäuse zur Aufnahme eines oder mehrerer Kabel bzw. Litzen, die jeweils endseitig an ihren äusseren Enden mit einem Kontaktteil versehen sind, der gemeinsam mit einem Teil des Kabels in einer im Kupplungselement bzw. Steckergehäuse vorgesehenen Bohrung aufgenommen und mittels einer Klebemasse in der Bohrung fixiert ist.The invention relates to a plug connection for electrical cable systems with a coupling element or connector housing for receiving one or more cables or strands, which are each provided at their ends with a contact part, which together with a part of the cable in a in the coupling element or plug housing provided bore and fixed in the bore by means of an adhesive.

Es ist allgemein bekannt, Steckverbindungen für elektrische Kabelsysteme mit einem Steckergehäuse so auszubilden, dass in den in dem Stekkergehäuse vorgesehenen Bohrungen zahlreiche Kabel bzw. Litzen aufgenommen werden können. Damit die einzelnen Litzen nicht aus dem Steckergehäuse herausgezogen werden können, sind diese mittels einer kautschukartigen Klebemasse in den im Steckergehäuse vorgesehenen Bohrungen festgeklebt, wobei die Kontaktteile der Litzen mit dem Gehäuse verrasten. Durch den Verguss der Klebemasse ergibt sich jedoch eine wesentlich höhere Ausreisskraft der Litzen aus dem Steckergehäuse. Die an den Litzen angeschlossenen Stecker dürfen jedoch nicht mit Klebemasse in Berührung kommen, damit sie beim Kupplungsvorgang sich gegenüber dem zugehörigen Kupplungsteil einer Litze ausrichten können. Die Verwendung einer kautschukartigen Klebemasse macht es erforderlich, dass für jeden einzelnen Stecker die Viskosität der Klebemasse genau festgelegt werden muss, um somit auch zu erreichen, dass die Klebemasse nicht an der Litze in der Bohrung vorbeiläuft und mit den einzelnen Kontakten in Berührung kommt.It is generally known to design plug connections for electrical cable systems with a plug housing in such a way that numerous cables or strands can be accommodated in the holes provided in the plug housing. So that the individual strands cannot be pulled out of the connector housing, they are glued into the holes provided in the connector housing by means of a rubber-like adhesive, the contact parts of the strands latching onto the housing. Potting the adhesive, however, results in a much higher pull-out force of the strands from the connector housing. However, the plugs connected to the strands must not come into contact with adhesive so that they can align themselves with the associated coupling part of a strand during the coupling process. The use of a rubber-like adhesive means that the viscosity of the adhesive has to be precisely defined for each individual connector, so that the adhesive does not run past the strand in the hole and comes into contact with the individual contacts.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, die einzelnen Litzen in einem Kupplungselement bzw. Steckergehäuse derart aufzunehmen und mit dem Kupplungselement bzw. Steckergehäuse zu verbinden, dass eine Berührung der Klebemasse mit den einzelnen Kontakten ausgeschaltet wird, auch dann, wenn in den einen gleichen Durchmesser aufweisenden Bohrungen Kabelteile mit unterschiedlichen Durchmessern eingeführt sind. Diese Aufgabe ist dadurch gelöst worden, dass zumindest ein Teil des Kabels mittels eines thixotropen Klebers in der Bohrung verklebt und durch Bewegung des Kabels bzw. des Kupplungselements oder des Stekkergehäuses und des das Kabel umgebenden Klebers die Eindringtiefe des Klebers in die Bohrung bestimmt wird. Durch die Verwendung eines thixotropen Klebers kann der Einfüllvorgang des Klebers in die entsprechende Bohrung, in der das Kabel aufgenommen ist, genau bestimmt werden, da durch die Bewegung des Steckergehäuses oder des Kupplungselements bzw. des zugehörigen Kabelstranges die Viskosität des Klebers verändert wird. Das Eindringen des Klebers in die entsprechenden Bohrungen wird so lange gewährleistet, solange die entsprechende Bewegung der einzelnen Kabel bzw. des Steckergehäuses erfolgt. Nach Beendigung des Bewegungsvorganges der einzelnen Teile verändert sich die Viskosität des Klebemittels derart, dass ein weiteres Eindringen des Klebemittels in die Bohrungen zu den einzelnen Kontakten ausgeschaltet wird. Hierdurch wird ein einwandfreier Sitz der einzelnen Kabel bzw. Litzen in den Bohrungen gewährleistet und gleichzeitig eine Zentriermöglichkeit des entsprechenden Kontaktes erreicht. Beim Kupplungsvorgang zwischen den einzelnen Kontakten ist ein selbsttätiges Ausrichten der Kontakte möglich. Die Verwendung des thixotropen Klebers gestattet auch das Eindringen in solche Bohrungen, in denen keine Kabel untergebracht sind; jedoch wird gleichzeitig sichergestellt, dass die Klebemasse nicht durch die Bohrungen hindurchläuft, da die einzelnen Teile der Steckverbindung nur kurzfristig bewegt werden. Dabei ist es vorteilhaft, dass der Kleber aus einem Harz-Härter-Gemisch auf Polyurethanbasis besteht, der im Bereich der oberen Öffnung der Bohrung einen Teil des Kabels mit dem Kupplungselement bzw. dem Steckergehäuse fest verbindet. Das Harz-Härter-Gemisch bzw. Zwei-Komponenten-Gemisch auf Polyurethanbasis gestattet einen einwandfreien Sitz des Kabels in der Bohrung, nachdem der Kleber ausgehärtet ist. Gleichzeitig wird eine einwandfreie Abdichtung mittels des Klebers erzielt, da sämtliche Öffnungen im Stekkergehäuse oder im Kupplungselement mittels der Klebemasse verschlossen werden können. Dabei spielt es keine Rolle, ob der Durchmesser der entsprechenden Bohrungen bzw. der Ringspalte zwischen dem Kabel und der Bohrung unterschiedlich gross ist. Durch fortlaufende Veränderungen der Viskosität des Klebers kann auf einfache Weise die Eindringtiefe in die Bohrung mit unterschiedlichem Durchmesser bestimmt werden. Hierzu ist es vorteilhaft, dass die Leerbohrungen im Kupplungsgehäuse bzw. im Steckergehäuse mittels Klebemasse im Bereich der Öffnung zur Aufnahme des Kabelteiles verschliessbar sind. Da der Kleber lediglich im oberen Bereich der Öffnung der entsprechenden Bohrungen zur Aufnahme des Kabels vorgesehen ist, wird sichergestellt, dass der Kleber nicht mit dem entsprechenden Kontakt des Kabels in Berührung kommt. Ein einwandfreies Zusammenstecken von Kupplung und Stecker erhält man dadurch, dass ein Teil des Kabels bzw. der Litze unbeweglich und Stecker bzw. Kontakthülsen zur Verbindung mit einem Gegenstück beweglich in der Bohrung aufgenommen ist. Hierzu ist es auch vorteilhaft, dass die einzelnen im Steckergehäuse vorgesehenen Bohrungen zur Aufnahme von Kabeln bzw. Litzen mit unterschiedlichem Durchmesser gleich gross sind und die Kabel mittels des thixotropen Klebers in den Bohrungen festsetzbar sind.In contrast, the object of the invention is to accommodate the individual strands in a coupling element or plug housing and to connect them to the coupling element or plug housing in such a way that contact of the adhesive with the individual contacts is switched off, even if they have the same diameter bores having cable parts with different diameters are introduced. This object has been achieved in that at least part of the cable is glued in the bore by means of a thixotropic adhesive and the depth of penetration of the adhesive into the bore is determined by moving the cable or the coupling element or the connector housing and the adhesive surrounding the cable. By using a thixotropic adhesive, the process of filling the adhesive into the corresponding hole in which the cable is accommodated can be precisely determined, since the viscosity of the adhesive is changed by the movement of the plug housing or the coupling element or the associated cable harness. The penetration of the adhesive into the corresponding holes is guaranteed as long as the corresponding movement of the individual cables or the connector housing takes place. After the movement of the individual parts has ended, the viscosity of the adhesive changes such that further penetration of the adhesive into the bores to the individual contacts is switched off. This ensures that the individual cables or strands are properly seated in the bores and at the same time that the corresponding contact can be centered. During the coupling process between the individual contacts, automatic alignment of the contacts is possible. The use of the thixotropic adhesive also allows penetration into holes in which no cables are accommodated; however, at the same time it is ensured that the adhesive does not run through the holes, since the individual parts of the plug connection are only moved for a short time. It is advantageous that the adhesive consists of a resin-hardener mixture based on polyurethane, which firmly connects part of the cable to the coupling element or the plug housing in the region of the upper opening of the bore. The resin-hardener mixture or two-component mixture based on polyurethane allows the cable to sit perfectly in the hole after the adhesive has hardened. At the same time, a perfect seal is achieved by means of the adhesive, since all openings in the connector housing or in the coupling element can be closed by means of the adhesive. It does not matter whether the diameter of the corresponding holes or the annular gap between the cable and the hole is different. Continuous changes in the viscosity of the adhesive make it easy to determine the depth of penetration into the hole with different diameters. For this purpose, it is advantageous that the empty bores in the coupling housing or in the connector housing can be closed by means of adhesive in the area of the opening for receiving the cable part. Since the adhesive is only provided in the upper area of the opening of the corresponding bores for receiving the cable, it is ensured that the adhesive does not come into contact with the corresponding contact of the cable. The coupling and plug can be properly put together by virtue of the fact that part of the cable or the strand is immovable and the plug or contact sleeves are movably received in the bore for connection to a counterpart. For this purpose, it is also advantageous that the individual bores provided in the connector housing for receiving cables or strands with different diameters are of the same size and the cables can be fixed in the bores by means of the thixotropic adhesive.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt:

  • Fig. 1 eine Querschnittdarstellung eines Kupplungselements einer Steckverbindung für elektrische Kabelsysteme,
  • Fig. 2 ein Steckergehäuse, mit dem das Kupplungselement gemäss Fig. 1 verschraubbar ist, wobei das Steckergehäuse für den Einfüllvorgang des Klebers um die Längsmittelachse des zugehörigen Kabelstranges bewegbar ist,
  • Fig. 3 eine Rütteleinrichtung für das Kupplungselement bzw. das Steckergehäuse zur Veränderung der Viskosität des Klebers.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. It shows:
  • 1 is a cross-sectional view of a coupling element of a connector for electrical cable systems,
  • 2 shows a connector housing with which the coupling element according to FIG. 1 can be screwed, wherein the plug housing for the filling process of the adhesive is movable about the longitudinal central axis of the associated cable harness,
  • Fig. 3 shows a vibrating device for the coupling element or the connector housing for changing the viscosity of the adhesive.

In der Zeichnung ist mit 10 ein Kupplungsteil bezeichnet, das auf einem Kupplungselement 12 drehbar angeordnet ist. Das Kupplungselement weist an seinem Aussenumfang ein Gewinde 14 zur Befestigung eines Kabelrohrs 16 und zahlreiche kleine Bohrungen 18 auf, die sich durch das Kupplungselement 12 erstrecken. Jede Bohrung 18 besteht aus einem ersten Bohrungsabschnitt 20, dessen Durchmesser grösser ist als der Durchmesser eines zweiten Bohrungsabschnittes 22. In dem zweiten Bohrungsabschnitt ist eine zylindrisch ausgebildete Kontakthülse 24 axial unverschiebbar, radial jedoch etwas beweglich angeordnet, die sich in den ersten Bohrungsabschnitt 20 erstreckt und an ihrem Ende eine Litze 26 aufnimmt, die mit mehreren Litzen in das Kabelrohr 16 eingezogen werden. Mit Bezug auf Fig. 1 ist der rechte Teil des Kupplungselements 12 mit einer zylindrischen Sackbohrung 28 versehen, die zur Aufnahme eines in Fig. 2 dargestellten Stekkergehäuses 30 dient. Wie aus Fig. 2 hervorgeht, ist das Steckergehäuse 30 mit einem Gewindeteil 32 versehen, der in den Kupplungsteil 10 eingeschraubt werden kann. Hierzu weist der Kupplungsteil 10 ebenfalls Gewindeteile 34 auf. Das in Fig. 2 dargestellte Steckergehäuse 30 ist mit einem rechteckförmigen vier Bohrungen 36 aufweisenden Flansch 38 ausgerüstet, der an eine entsprechende am Arbeitsgerät vorgesehene Halterung 40 angeschraubt werden kann.In the drawing, 10 denotes a coupling part which is rotatably arranged on a coupling element 12. The coupling element has on its outer circumference a thread 14 for fastening a cable pipe 16 and numerous small bores 18 which extend through the coupling element 12. Each bore 18 consists of a first bore section 20, the diameter of which is larger than the diameter of a second bore section 22. In the second bore section, a cylindrical contact sleeve 24 is axially immovable, but radially somewhat movable, which extends into the first bore section 20 and at its end receives a strand 26, which are drawn into the cable tube 16 with several strands. With reference to FIG. 1, the right part of the coupling element 12 is provided with a cylindrical blind bore 28, which serves to receive a connector housing 30 shown in FIG. 2. As can be seen from FIG. 2, the connector housing 30 is provided with a threaded part 32 which can be screwed into the coupling part 10. For this purpose, the coupling part 10 also has threaded parts 34. The connector housing 30 shown in FIG. 2 is equipped with a rectangular flange 38 having four bores 36 which can be screwed onto a corresponding holder 40 provided on the implement.

Um die in den ersten Bohrungsabschnitten 20 aufgenommenen Litzen 26 mit den Bohrungsabschnitten 20 fest zu verbinden, werden der Kupplungsteil 10 und das Steckergehäuse 30 beispielsweise auf einen Rütteltisch 42 montiert. Der Rütteltisch 42 kann hierzu mit einem Ringflansch 44 zur Aufnahme des Kupplungsteils 10 bzw. des Steckergehäuses 30 ausgerüstet sein. Nach Montage des Kupplungsgehäuses wird die Litze 26 mit der zugehörigen Kontakthülse 24 in die Bohrung 18 eingeführt, bis sie an den Boden der Sacklochbohrung 28 herangeführt ist. Danach kann die Litze im ersten Bohrungsabschnitt 20 mittels eines kleinen Keiles mittig zum Bohrungsabschnitt ausgerichtet werden. Da die Kontakthülsen 24 der Litzen im zweiten Bohrungsabschnitt etwas seitenbeweglich sind, erfolgt die genaue Zentrierung der Kontakthülsen durch Einführen von Gegenkontaktstiften beim Kuppeln von Steckergehäuse 30 und Kupplungsteil 10. Anschliessend wird eine thixotrope Klebemasse in die zahlreichen Bohrungen 18 (gemäss Fig. 3) von oben eingegeben und dabei gleichzeitig der Kupplungsteil 10 mittels des Rütteltisches 42 so bewegt, dass die Viskosität des Klebers verändert wird und dieser in die Bohrungen eindringen kann. Ist genügend Kleber in die einzelnen Bohrungen eingedrungen, ohne dass dabei die Kontakthülse mit dem Kleber in Berührung gebracht worden ist, wird das Rütteln des Kupplungsteils 10 beendet, und die Viskosität des Klebers verändert sich so schnell, dass ein weiteres Nachfliessen des Klebers in die Bohrungen ausgeschaltet wird. Aus Fig. 3, in der der Kleber mit 46 bezeichnet ist, geht hervor, dass lediglich im oberen Bereich der Bohrungen 18 der Kleber eingedrungen ist. Durch Veränderungen der Viskosität des Klebers wird auch ein Eindringen des Klebers in relativ kleine Ringspalte oder Bohrungen gewährleistet. Ausserdem wird bei relativ grossem Bohrungsdurchmesser der einzelnen Bohrungen verhindert, dass der Kleber zu weit in die Bohrung eindringt. Um die Viskosität des Klebers zu verändern, kann auch das Steckergehäuse 30 gemäss Fig. 2 um die Mittelachse des Kabelrohrs 16 ein-oder zweimal bewegt werden, wobei ausreichend viel Kleber in die entsprechenden Bohrungen bzw. Ringspalte des Steckergehäuses eindringt. Die Verwendung eines thixotropen Klebers gestattet also eine einwandfreie Abdichtung aller im Steckergehäuse vorgesehenen Öffnungen, da der Kleber ohne weiteres auch in relativ kleine Bohrungen eindringen kann und diese somit gegenüber den Kontakten bzw. den Kontakthülsen abdichtet. Nachdem der Kleber in die entsprechenden Bohrungen bzw. Öffnungen im Kupplungselement 12 bzw. des Steckergehäuses 30 eingeführt worden ist, wird zur Veränderung der Viskosität des Klebers der Rüttelvorgang der einzelnen Teile eingestellt, um dann den Kleber entsprechend aushärten zu lassen.In order to firmly connect the strands 26 received in the first bore sections 20 to the bore sections 20, the coupling part 10 and the plug housing 30 are mounted, for example, on a vibrating table 42. For this purpose, the vibrating table 42 can be equipped with an annular flange 44 for receiving the coupling part 10 or the plug housing 30. After assembly of the coupling housing, the strand 26 with the associated contact sleeve 24 is inserted into the bore 18 until it leads to the bottom of the blind bore 28. The strand in the first bore section 20 can then be aligned in the center of the bore section using a small wedge. Since the contact sleeves 24 of the strands are somewhat laterally movable in the second bore section, the exact centering of the contact sleeves takes place by inserting mating contact pins when the connector housing 30 and coupling part 10 are coupled entered and at the same time the coupling part 10 is moved by means of the vibrating table 42 in such a way that the viscosity of the adhesive is changed and the adhesive can penetrate into the bores. If sufficient adhesive has penetrated into the individual bores without the contact sleeve having been brought into contact with the adhesive, the shaking of the coupling part 10 is stopped and the viscosity of the adhesive changes so quickly that the adhesive continues to flow into the bores is turned off. 3, in which the adhesive is denoted by 46, it can be seen that the adhesive has penetrated only in the upper region of the bores 18. Changes in the viscosity of the adhesive also ensure that the adhesive penetrates into relatively small annular gaps or bores. In addition, the relatively large bore diameter of the individual bores prevents the adhesive from penetrating too far into the bore. In order to change the viscosity of the adhesive, the connector housing 30 according to FIG. 2 can also be moved once or twice about the central axis of the cable tube 16, with a sufficient amount of adhesive penetrating into the corresponding bores or annular gaps in the connector housing. The use of a thixotropic adhesive thus permits a perfect seal of all openings provided in the connector housing, since the adhesive can easily penetrate into relatively small bores and thus seal them against the contacts or the contact sleeves. After the adhesive has been inserted into the corresponding bores or openings in the coupling element 12 or the connector housing 30, the shaking process of the individual parts is adjusted to change the viscosity of the adhesive, in order then to allow the adhesive to harden accordingly.
