The insert is formed by two semi circular ring sections with engaging surfaces Ä65Ü

Description

Die Erfindung betrifft ein Endgehäuse für einen Steckverbinder mit einem Außengehäuse und einem Zahnkranz. Derartige Endgehäuse sind z.B. von der Firma FILCON Elektronik Vertriebsgesellschaft für Bauelemente und Geräte mbH in Taufkirchen, Deutschland, unter der Bezeichnung Paratron® zu beziehen.The invention relates to an end housing for a connector with an outer housing and a ring gear. Such end housings are e.g. from the company FILCON Elektronik Vertriebsgesellschaft für Bauelemente und Geräte mbH in Taufkirchen, Germany, under the name Paratron®.

Fig. 1 zeigt ein Beispiel eines von der Firma FILCON hergestellten Paratron® Gehäuses. Es besteht aus einem metallischen Außengehäuse 11 mit einer kabeleinfuhrseitigen Stirnwand 13, in der eine Durchtrittsöffnung 15 gebildet ist. In der Durchtrittsöffnung 15 befindet sich eine Hülse 17, die einen aus dem Außengehäuse 11 herausragenden Außenteil 19 mit einem Außengewinde 21 und einen an der Innenseite der Stirnwand 13 anliegenden radialen Flansch 23 aufweist. Auf das Außengewinde 21 ist eine Gewindemutter 25 aufgeschraubt, mittels welcher die Seitenwand 13 und der Flansch 23 aneinander befestigt werden. An das aus dem Außengehäuse 11 herausragende Ende der Hülse 17 schließt sich ein Außenisoliermantel 27 eines elektrischen Kabels 29 an.1 shows an example of a Paratron® housing manufactured by FILCON. It consists of a metallic outer housing 11 with a cable entry end wall 13 in which a passage opening 15 is formed. In the passage opening 15 there is a sleeve 17, which has an outer part 19 protruding from the outer housing 11 with an external thread 21 and a radial flange 23 abutting the inside of the end wall 13. A threaded nut 25 is screwed onto the external thread 21, by means of which the side wall 13 and the flange 23 are fastened to one another. An outer insulating jacket 27 of an electrical cable 29 connects to the end of the sleeve 17 protruding from the outer housing 11.

Das Paratron® Endgehäuse ist zur Verwendung in einem Steckverbinder bestimmt, in welchem das Kabel 29 mit Schirm versehen ist. Um solche Kabel mit dem Stecker zu verbinden, wird ein Stück des Außenisoliermantels 27 des Kabels 29 abgemantelt. Auf den so freigelegten Schirm wird die Hülse 17 des Endgehäuses 11 aufgeschoben. Die Hülse 17 weist eine Durchführöffnung auf, die so an den Außendurchmesser des Schirms angepaßt ist, daß die Hülse gerade auf die Schirmen des Kabels 29 aufgeschoben werden kann. Die Hülse 17 weist einen Hülsenfortsatz 35 auf. Nach vollständigem Aufschieben der Hülse 17 kann der freigelegte Schirm des Kabels 29 um den Hülsenfortsatz 35 herumgeschlagen werden.The Paratron® end housing is intended for use in a connector in which the cable 29 is shielded. In order to connect such cables to the plug, a piece of the outer insulating jacket 27 of the cable 29 is stripped. The sleeve 17 of the end housing 11 is pushed onto the screen thus exposed. The sleeve 17 has a feed-through opening which is adapted to the outer diameter of the screen in such a way that the sleeve can just be pushed onto the screens of the cable 29. The sleeve 17 has a sleeve extension 35. After the sleeve 17 has been completely pushed on, the exposed shield of the cable 29 can be folded around the sleeve extension 35.

Der Aufbau dieser Art Steckverbinder ist vollständig in der deutschen Patentschrift DE-C-40 13 963 beschrieben.The structure of this type of connector is fully described in German patent DE-C-40 13 963.

Das Paratron® Endgehäuse weist weiter einen sich innerhalb des Außengehäuses 11 befindenden Zahnkranz 33 auf. Der Zahnkranz 33 ist derart ausgebildet, daß er an einen Zahnkranz 37 eines passenden Steckverbinders 40 angepaßt ist. Dabei passen die Zähne der jeweiligen Zahnkränze 33, 37 nach Einschrauben des Steckverbinders 40 mittels einer Überwurfmutter in das Endgehäuse 11 ineinander hinein, so daß der Steckverbinder 40 relativ zum Außengehäuse 11 nach Einschrauben nicht verdreht werden kann.The Paratron® end housing further has a ring gear 33 located inside the outer housing 11. The ring gear 33 is designed such that it is adapted to a ring gear 37 of a suitable connector 40. The teeth of the respective sprockets 33, 37 fit into each other after screwing the connector 40 into the end housing 11 by means of a union nut, so that the connector 40 cannot be rotated relative to the outer housing 11 after screwing in.

Steckverbinder der eingangs beschriebenen Art haben den Nachteil, daß der Durchmesser des anzuschließenden Kabels 29 und der Durchmesser der Hülse 17 durch den Durchmesser des Zahnkranzes 33 begrenzt sind. Dieser Nachteil ist in Fig. 2A und Fig. 2B dargestellt. Fig. 2A ist eine vereinfachte Draufsicht des Endgehäuses 11 und Fig. 2B ist eine vereinfachte Längssicht des Endgehäuses 11. In beiden Figuren hat die Öffnung im Zahnkranz 33 einen Durchmesser D1, der kleiner ist als der Durchmesser D2 des Gewindes 54 für den Steckverbinder 40. So kann zum Beispiel bei den Paratron® Gehäusen der Zahnkranz 33 einen Innendurchmesser D1 von 9 mm haben, wohingegen das Gewinde 54 einen Durchmesser D2 von 13 mm hat. Dieser Nachteil kann dadurch überwunden werden, daß ein Adapterring verwendet wird, um einen Steckverbinder 40 an ein größeres Endgehäuse anzupassen. Solche Adapterringe sind auch in der Paratron® Serie verfügbar. Dabei wird aber das Gesamtgewicht des Steckverbinders (Endgehäuse 11 und Adapterring) größer, was in gewichtskritischen Anwendungen nachteilig ist.Connectors of the type described above have the disadvantage that the diameter of the cable 29 to be connected and the diameter of the sleeve 17 are limited by the diameter of the ring gear 33. This disadvantage is shown in FIGS. 2A and 2B. 2A is a simplified top view of the end housing 11 and FIG. 2B is a simplified longitudinal view of the end housing 11. In both figures, the opening in the ring gear 33 has a diameter D1 that is smaller than the diameter D2 of the thread 54 for the connector 40. For example, in the Paratron® housings, the ring gear 33 can have an inner diameter D1 of 9 mm, whereas the thread 54 has a diameter D2 of 13 mm. This disadvantage can be overcome by using an adapter ring to adapt a connector 40 to a larger end housing. Such adapter rings are also available in the Paratron® series. However, the total weight of the connector (end housing 11 and adapter ring) becomes larger, which is disadvantageous in weight-critical applications.

Dieses Problem wird gemäß der Erfindung dadurch gelöst, daß der Zahnkranz 33 vom Außengehäuse 11 lösbar ist Durch diese Anordnung ist es möglich, das Kabel 29 zunächst durch die Durchtrittsöffnung 15 einzuführen. Danach wird die Hülse 17 am Ende des Kabels 29 angebracht und in das Außengehäuse 11 eingezogen. Anschließend wird der Zahnkranz 33 in die der Stirnwand gegenüberliegenden Öffnung des Außengehäuses 11 eingebracht. Nach dieser erfindungsgemäßen Lösung ist die Hülse 17 im Durchmesser grösser als der Durchmesser D1 der Öffnung im Zahnkranz 33 und sie kann durch diese Öffnung nicht durchgehen.This problem is solved according to the invention in that the toothed ring 33 can be detached from the outer housing 11. This arrangement makes it possible to first insert the cable 29 through the passage opening 15. Then the sleeve 17 is attached to the end of the cable 29 and drawn into the outer housing 11. Then the ring gear 33 is introduced into the opening of the outer housing 11 opposite the end wall. According to this solution according to the invention, the sleeve 17 is larger in diameter than the diameter D1 of the opening in the ring gear 33 and it cannot pass through this opening.

Da dieses erfindungsgemäße Gehäuse Kabel mit einem größeren Durchmesser aufnehmen kann, ist in vielen Fällen ein Adapterring und somit zusätzliches Gewicht gespart. Die Herstellung solcher Endgehäuse wird auch dadurch vereinfacht, daß der Zahnkranz nicht mehr zusammen mit dem Außengehäuse im gleichen Metallstück gefertigt werden muß. Der Zahnkranz kann daher in einem separaten Vorgang hergestellt werden, der aufgrund der komplizierteren Konstruktion des Zahnkranzes von Vorteil ist.Since this housing according to the invention can accommodate cables with a larger diameter, an adapter ring and is in many cases thus saving additional weight. The manufacture of such end housings is also simplified in that the ring gear no longer has to be manufactured together with the outer housing in the same metal piece. The ring gear can therefore be produced in a separate process, which is advantageous due to the more complicated construction of the ring gear.

In einer Ausführungsform besteht der Zahnkranz aus mindestens zwei Teilen, die zusammenbringbar sind. Dieses hat den Vorteil, daß die Montage des Zahnkranzes im Endgehäuse vereinfacht wird. Zum Einbringen des Zahnkranzes innerhalb des Außengehäuses hat der Zahnkranz vorzugsweise ein auf ein Innengewinde des Außengehäuses anpaßtes Gewinde. Diese Gewinde erlaubt das Einschrauben des Zahnkranzes in das Endgehäuse.In one embodiment, the ring gear consists of at least two parts that can be brought together. This has the advantage that the assembly of the ring gear in the end housing is simplified. To insert the ring gear within the outer housing, the ring gear preferably has a thread which is adapted to an internal thread of the outer housing. This thread allows the ring gear to be screwed into the end housing.

In einer weiteren Ausführungsform weist die Oberfläche des Zahnkranzes Mulden auf. Das Außengehäuse hat entsprechende Ausnehmungen mit Kugel und Feder, wobei die Kugeln derart ausgebildet sind, daß sie in die Mulden des Zahnkranzes hineinpassen. Mit Hilfe dieser Anordnung wird der Zahnkranz im Außengehäuse gesichert.In a further embodiment, the surface of the ring gear has troughs. The outer housing has corresponding recesses with ball and spring, the balls being designed such that they fit into the troughs of the ring gear. With the help of this arrangement, the ring gear is secured in the outer housing.

Um weiter Gewicht zu sparen, kann das Außengehäuse aus Kunststoff mit einer metallischen Schicht ausgebildet werden. Das Außengehäuse kann auch aus einem elektrisch leitenden Kunststoff gefertigt werden.In order to further save weight, the outer housing can be made of plastic with a metallic layer. The outer housing can also be made from an electrically conductive plastic.

Das erfindungsgemäße Endgehäuse findet Anwendung mit einem Steckverbinder zum Anschließen eines Kabel oder Kabelbündels mit einer Hülse. Dieser Steckverbinder kann auch aus Kunststoff mit einer Metallschicht bestehen.The end housing according to the invention is used with a plug connector for connecting a cable or bundle of cables with a sleeve. This connector can also be made of plastic with a metal layer.

Der Steckverbinder wird in einem Kabelverbindungssystem mit einer an dem Steckverbinder angepaßten Steckerbuchse verwendet.The connector is used in a cable connection system with a socket adapted to the connector.

Fig. 3 zeigt ein Endgehäuse nach der Erfindung. Das Endgehäuse hat ein Außengehäuse 11 mit einer kabeleinfuhrseitigen Stirnwand 13, in der eine Durchtrittsöffnung 15 ausgebildet ist. Innerhalb des Außengehäuses 11 befindet sich eine Hülse 17, die einen im Endzustand herausragenden Außenteil 19 mit einem Außengewinde 21, einen an der Innenseite der Stirnwand 13 anliegenden radialen Flansch 23 sowie einen Hülsenfortsatz 35 zur Aufnahme des freigelegten Schirms eines nicht dargestellten Kabels aufweist.Fig. 3 shows an end housing according to the invention. The end housing has an outer housing 11 with an end wall 13 on the cable entry side, in which an opening 15 is formed. Inside the outer housing 11 there is a sleeve 17 which has an outer part 19 which projects in the final state and has an external thread 21, a radial flange 23 which bears against the inside of the end wall 13 and a sleeve extension 35 for receiving the exposed shield of a cable (not shown).

An seiner anderen, der Durchtrittsöffnung 15 entgegensetzten Öffnung 43 hat das Außengehäuse 11 ein Innengewinde 45. Das Innengewinde 45 dient der Aufnahme des Steckverbinders 40 sowie dem Einschrauben eines Zahnkranzes 50. Der Zahnkranz 50 ist außerhalb des Außengehäuses 11 dargestellt. Er ist zylinderförmig ausgestaltet und hat Verzahnungen 57 sowie ein an das Innengewinde 45 des Außengehäuses 11 angepaßtes Außengewinde 55. Aufgrund des Innengewindes 45 und des Zahnkranz-Außengewindes 55 kann der Zahnkranz 50 durch die Öffnung 43 in das Außengehäuse 11 eingeschraubt werden. Die Verzahnungen 57 des Zahnkranzes 50 sind den Verzahnungen 37 des Steckverbinders 40 angepaßt.The outer housing 11 has an internal thread 45 at its other opening 43 opposite the passage opening 15. The internal thread 45 serves to receive the connector 40 and to screw in a ring gear 50. The ring gear 50 is shown outside the outer housing 11. It is cylindrical and has toothing 57 and an external thread 55 adapted to the internal thread 45 of the external housing 11. Due to the internal thread 45 and the external gear ring 55, the internal gear 50 can be screwed into the external housing 11 through the opening 43. The teeth 57 of the ring gear 50 are adapted to the teeth 37 of the connector 40.

Das Außengehäuse 11 weist einen das Gweinde 45 begrenzenden, einen Anschlag für den Zahnkranz 50 bildenden Freisich 58 auf.The outer housing 11 has an undercut 58 which delimits the thread 45 and forms a stop for the ring gear 50.

Auch andere Vorrichtungen können zum Festmachen des Zahnkranzes 50 im Außengehäuse 11 verwendet werden. Die Oberfläche des Zahnkranzes 50 kann z.B. glatt ausgestaltet werden. Dabei kann der Zahnkranz 50 in das Außengehäuse 11 eingeschoben werden und mittels eines Klebstoffes, einer Klemm - oder Hakenvorrichtung oder eines Spannrings im Außengehäuse 11 befestigt werden. Der verwendete Klebstoff sollte leitfähig sein, u.a. kann leitfähiger Schraubenssicherungslack verwendet werden.Other devices can also be used to secure the ring gear 50 in the outer housing 11. The surface of the ring gear 50 can e.g. be made smooth. In this case, the ring gear 50 can be pushed into the outer housing 11 and fastened in the outer housing 11 by means of an adhesive, a clamping or hook device or a clamping ring. The adhesive used should be conductive, including conductive screw locking lacquer can be used.

In einer bevorzugten Ausführungsform der Erfindung wird der Zahnkranz 50 aus zwei oder mehreren Teilen gebildet, wie in Fig. 4A und Fig. 4B dargestellt wird. In diesen Figuren ist gezeigt, wie der Zahnkranz 50 sich durch einen Schnitt 65 (vorzugsweise zig-zag-förmig) in zwei Teile lösen läßt. Diese Anordnung hat den Vorteil, daß der Zahnkranz 50 einfacher um ein aus der Öffnung 43 herausragendes Kabel 29 angeordnet werden kann.In a preferred embodiment of the invention, the ring gear 50 is formed from two or more parts, as shown in FIGS. 4A and 4B. These figures show how the ring gear 50 can be separated into two parts by a cut 65 (preferably zig-zag). This arrangement has the advantage that the ring gear 50 can be arranged more easily around a cable 29 protruding from the opening 43.

Nach Einschrauben des Zahnkranzes 50 in das Endgehäuse 11 werden die zwei (oder mehrere) Teile des Zahnkranzes 50 ohne zusätzliches Mittel zusammengehalten. Alternativ kann eine Klemm- oder Hakenvorrichtung, Klebstoff oder leitfähiger Schraubenssicherungslack verwendet werden, um die Teile des Zahnkranzes 50 zusammenzuhalten. Der Klebstoff ist vorzugsweise leitfähig.After screwing the ring gear 50 into the end housing 11, the two (or more) parts of the ring gear 50 are held together without additional means. Alternatively, a clamp or hook device, adhesive, or conductive threadlocker varnish can be used to hold the parts of the ring gear 50 together. The adhesive is preferably conductive.

Eine weitere Ausführungsform der Erfindung ist in Fig. 5 dargestellt. Das Außengehäuse 11 hat in einer Ausdehnung 47 zusätzlich Bohrungen 77. In diesen Bohrungen 77 befinden sich Kugeln 75 am offenen, am Innenteil des Außengehäuses liegenden Ende der Bohrungen 77.
