Description

Stand der TechnikState of the art

Die vorliegende Erfindung betrifft eine Steckverbindungsanordnung, insbesondere eine Steckverbindungsanordnung, die an einem Getriebedeckel eines Scheibenwischermotors vorgesehen ist.The present invention relates to a connector assembly, in particular a connector assembly which is provided on a gear cover of a windshield wiper motor.

Aus der US 5,213,225 ist eine Verbindungsanordnung bekannt, die an einem Getriebedeckel des Getriebes eines Scheibenwischermotors vorgesehen ist. Die Verbindungsanordnung stellt eine Verbindung zwischen den internen elektrischen Leitungen eines Elektronikmoduls und einer elektrischen Zuleitung von außen her. Das Elektronikmodul ist im Getriebegehäuse angebracht. Bei diesem handelt es sich in diesem Fall um einen Autostop-Mechanismus, der die Auslenkung der Scheibenwischer begrenzt. An der Verbindungsanordnung sind Schraublöcher für deren Befestigung der Verbindungsanordnung am Getriebedeckel vorgesehen.From the US 5,213,225 a connection arrangement is known, which is provided on a gear cover of the transmission of a windscreen wiper motor. The connection arrangement establishes a connection between the internal electrical lines of an electronic module and an electrical supply line from the outside. The electronic module is mounted in the gearbox housing. In this case, this is an autostop mechanism that limits the deflection of the windshield wipers. At the connection arrangement screw holes are provided for the attachment of the connection assembly on the gear cover.

Die Befestigung durch Schrauben erfordert jedoch allgemein einen hohen Zeit- und Arbeitsaufwand, wodurch die Fertigungskosten erhöht werden. Vorzuziehen wäre daher eine Verbindungsanordnung, die nur eingesteckt und nicht festgeschraubt werden muß, gleichzeitig aber eine genaue Positionierung der Verbindung zu den internen elektrischen Leitungen erlaubt.The fastening by screws, however, generally requires a great deal of time and labor, whereby the manufacturing costs are increased. It would therefore be preferable to have a connection arrangement which only has to be plugged in and not screwed on, but at the same time permits an exact positioning of the connection to the internal electrical lines.

Die DE 198 48 732 offenbart eine gattungsbildende Steckverbindungsanordnung. Der Steckerkörper weist einen Steckerkopf und einem Steckelement auf. Mehrere elektrische Leitungen verlaufen vom Steckerkopf zum Steckelement und enden in elektrischen Kontakten. Der Stecker ist in eine Öffnung eingestreckt, die in einer Wand eines Getriebes ausgebildet ist. Ein Nachteil dieser Steckverbindungsanordnung liegt insbesondere in der fehlenden Abdichtung. Diese Steckverbindungsanordnung ist daher für das Getriebe eines Scheibenwischermotors nicht geeignet.The DE 198 48 732 discloses a generic connector assembly. The plug body has a plug head and a plug-in element. Several electrical cables run from the plug head to the plug element and end in electrical contacts. The plug is stretched in an opening formed in a wall of a transmission. A disadvantage of this connector assembly is in particular in the missing seal. This connector assembly is therefore not suitable for the transmission of a windshield wiper motor.

Aus der US-A-4 589 719 ist eine Steckverbindungsanordnung mit den Merkmalen des Oberbegriffs des Anspruchs 1 bekannt.From the US-A-4 589 719 is a connector assembly with the features of the preamble of claim 1 is known.

AufgabenslellungAufgabenslellung

Der vorliegenden Erfindung liegt: die Aufgabe zu Grunde, eine verbesserte Steckverbindungsanordnung zu schaffen, deren Herstellung einen geringen. Zeit- und Arbeitsaufwand erfordert.The present invention is based on the object: to provide an improved connector assembly, whose production has a low. Time and effort required.

Die der Erfindung zugrunde liegende Aufgabe wird durch einen Steckverbindungsanordnung mit den Merkmalen des kennzeichnenden Teils des Patentanspruchs 1 gelöst.The object underlying the invention is achieved by a connector assembly having the features of the characterizing part of patent claim 1.

Erfindungsgemäß ist der Steckerkörper in der Öffnung befestigbar, indem das Steckelement und ein Riegelelement ineinandergreifen.According to the invention, the plug body can be fastened in the opening by the plug element and a locking element interlocking.

Vorteilhafterweise ermöglicht das Ineinandergreifen eine genaue Positionierung der mindestens einen elektrischen Leitung.Advantageously, the meshing enables accurate positioning of the at least one electrical lead.

In einer Ausführungsform ist am Steckelement eine Ausnehmung vorgesehen, in die das Riegelelement einschiebbar ist.In one embodiment, a recess is provided on the plug element, into which the locking element can be inserted.

In dieser Ausführungsform weist das Steckelement ein auskragendes Stützelement auf, an dem eine elastische Dichtung angebracht ist.In this embodiment, the plug-in element has a cantilevered support element on which an elastic seal is attached.

Das Riegelelement weist eine keilförmige Spitze auf, die es ermöglicht, beim Einschieben des Riegelelements das Steckelement gegen eine von der Dichtung ausgeübte elastische Kraft weiter in die Öffnung zu ziehen.The locking element has a wedge-shaped tip, which makes it possible, when inserting the locking element, to pull the plug-in element against an elastic force exerted by the seal further into the opening.

FIG. 1 zeigt ein erstes Beispiel einer Steckverbindungsanordnung. Ein Stecker, der vorzugsweise durch Spritzguß hergestellt wurde, weist einen Steckerkörper 1 mit einem Steckerkopf 2 und einem Steckelement 3 auf. Das Steckerkopf 2 und das Steckelement 3 sind rechtwinklig zueinander angeordnet und können einstückig ausgebildet sein. Der Steckerkopf 2 ist dadurch definiert, daß er der Teil des Steckerkörpers ist, der zum Einführen eines externen Kabels vorgesehen ist. Das Steckelement 3 ist dadurch definiert, daß es der Teil des Steckerkörpers 1 ist, der zum Einstecken in eine Öffnung in einer Wand vorgesehen ist. Steckerkopf 2 und Steckelement 3 müssen konstruktiv nicht deutlich voneinander abgegrenzt sein. Eine elektrische Leitung 4 verläuft durch das Innere des Steckerkörpers 1 von dem Steckerkopf 2 zu dem Steckelement 3, wo sie in einem elektrischen Kontakt 5 endet. Im Steckerkopf 2 ist eine Halterungsausnehmung 6 zur Befestigung des externen Kabels ausgebildet. Das Steckelement 3 ist zylindersymmetrisch aufgebaut und weist ein auskragendes Stützelement 7 auf, das auf einer Wand 8, die im Schnitt dargestellt ist und zu einem Getriebedeckel gehört, aufliegt. Die Wand 8 ist Teil eines Gehäusedeckels eines Getriebes und besteht vorzugsweise aus Metall. Zwischen der Wand 8 und dem Stützelement 7 verläuft ein Dichtungsring 9, der am Stützelement 7 befestigt ist. FIG. 1 shows a first example of a connector assembly. A plug, which was preferably produced by injection molding, has a plug body 1 with a plug head 2 and a plug-in element 3. The plug head 2 and the plug element 3 are arranged at right angles to each other and may be formed in one piece. The plug head 2 is defined as being the part of the plug body intended for insertion of an external cable. The plug-in element 3 is defined by being the part of the plug body 1 which is intended to be plugged into an opening in a wall. Plug head 2 and 3 plug element must be structurally not clearly separated from each other. An electrical line 4 extends through the interior of the plug body 1 from the plug head 2 to the plug element 3, where it ends in an electrical contact 5. In the plug head 2, a Halterungsausnehmung 6 is formed for attachment of the external cable. The plug-in element 3 is constructed cylindrically symmetrical and has a cantilevered support element 7, which rests on a wall 8, which is shown in section and belongs to a gear cover. The wall 8 is part of a housing cover of a transmission and consists preferably made of metal. Between the wall 8 and the support member 7 extends a sealing ring 9 which is fixed to the support member 7.

An dem Steckelement 3 ist ein Gewinde mit mehreren spiralförmigen Vorsprüngen 10 ausgebildet. Der Dichtungsring 9 ist im Schnitt dargestellt, so daß er das Gewinde nicht teilweise verdeckt. Das Gewinde des Steckerkörpers 1 ist in eine Öffnung (siehe FIG. 2) in der Wand 8 eingedreht. Dabei sind die spiralförmigen Vorsprünge 10 in an Rand der Öffnung befindliche Aussparungen 11 eingeführt. Aufgrund der zylindrischen Form liegt das Steckelement 3 beim Eindrehen immer am Rand der Öffnung an und ist somit fest positioniert.On the plug-in element 3, a thread with a plurality of spiral-shaped projections 10 is formed. The sealing ring 9 is shown in section, so that it does not partially cover the thread. The thread of the plug body 1 is in an opening (see FIG. 2 ) is screwed in the wall 8. In this case, the spiral-shaped projections 10 are inserted into recesses 11 located at the edge of the opening. Due to the cylindrical shape, the plug-in element 3 is always at the edge of the opening during insertion and is thus firmly positioned.

An dem spiralförmigen Vorsprung 10 ist eine Nase 12 ausgebildet, die eine parallel zum Rand der Aussparung 11 verlaufende Flanke aufweist. Die Position der Nase 12 ist so gewählt, daß die Kontakte 5 richtig positioniert sind, sobald sich die Nase 12 vollständig in der Aussparung 11 befindet. Ein weiteres Eindrehen des Steckers wird dann durch das Stützelement 7 blockiert. Dabei wird der Dichtungsring 9 stark zusammengedrückt, so daß der Stecker gut abgedichtet ist, wie es für einen Scheibenwischermotor erforderlich ist.On the spiral projection 10, a nose 12 is formed, which has a parallel to the edge of the recess 11 extending edge. The position of the nose 12 is chosen so that the contacts 5 are correctly positioned as soon as the nose 12 is completely in the recess 11. A further screwing in of the plug is then blocked by the support element 7. In this case, the sealing ring 9 is strongly compressed, so that the plug is well sealed, as is required for a windscreen wiper motor.

Beim Eindrehen des Steckers 1 wird die Nase 12 gegen die Wand 8 gedrückt. Die Wand 8 gibt dann elastisch nach (dies wird mit Bezugnahme auf FIG. 2 noch näher erläutert) und kehrt hinter der Nase 12 wieder in ihre Ausgangslage zurück. Die Nase 12 verhakt sich mit der Wand 8 und verhindert das Herausdrehen des Steckers 1. Alternativ zu der Nase 12 kann auch die Steigung des spiralförmigen Vorsprungs 10 so gering gewählt und so auf die Größe der Aussparung 11 abgestimmt werden, daß der spiralförmige Vorsprung 10 gegen die Wand 8 drückt. Dann sollte die Steigung des Vorsprungs an der Stelle, die zuerst in die Aussparung eingeführt wird jedoch steiler gewählt werden, um das Eindrehen des Vorsprungs unter der Wand 8 zu erleichtern. Der spiralförmige Vorsprung wird dann vollständig in die Aussparung eingedreht und die Wand 8 kehrt hinter dem spiralförmigen Vorsprung 10 in ihre Ausgangslage zurück. Das Ende des spiralförmigen Vorsprungs ersetzt also die Nase 12. In der ersten Ausführungsform bedeutet das Ineinandergreifen des Steckelements 3 und der Wand 9 also konkret, daß der spiralförmige Vorsprung 10 bzw. eine am spiralförmigen Vorsprung 10 angebrachte Nase 12 am Rand der Aussparung 11 anliegt. Dabei sind die Kontakte 5 für eine Verbindung mit internen Leitungen geeignet positioniert.When screwing in the plug 1, the nose 12 is pressed against the wall 8. The wall 8 then yields elastically (this will be with reference to FIG FIG. 2 explained in more detail) and returns behind the nose 12 back to their original position. The nose 12 hooks with the wall 8 and prevents unscrewing of the plug 1. Alternatively to the nose 12 and the slope of the spiral projection 10 can be chosen so small and matched to the size of the recess 11 that the spiral projection 10 against the wall 8 suppressed. Then, however, the slope of the protrusion at the location first inserted into the recess should be steeper to facilitate screwing the protrusion under the wall 8. The helical projection is then completely screwed into the recess and the wall 8 returns behind the helical projection 10 to its original position. Thus, the end of the helical projection replaces the nose 12. In the first embodiment, the engagement of the male element 3 and the wall 9 thus means concretely that the helical projection 10 or a nose 12 attached to the helical projection 10 rests against the edge of the recess 11. The contacts 5 are suitably positioned for connection to internal lines.

FIG. 2 zeigt die Öffnung 13 in dem Gehäusedeckel. An ihrem Rand sind die Aussparungen 11 als Ringsektoren ausgebildet. In der Wand 8 ist ein Schlitz 14 ausgebildet, der in der Aussparung 11 endet. Durch den Schlitz 14 wird eine Zunge 15 mit der gleichen Breite wie die Aussparung und der spiralförmige Vorsprung 10 geschaffen, die unter Druckbelastung aufgrund der Nase 12 bzw. des spiralförmigen Vorsprungs 10 nachgibt. Sobald sich die Nase 12 bzw. der spiralförmige Vorsprung 10 vollständig in der Aussparung 11 befindet, schnalzt die Zunge 15 in ihre Ausgangslage zurück. FIG. 2 shows the opening 13 in the housing cover. At its edge, the recesses 11 are formed as ring sectors. In the wall 8, a slot 14 is formed, which ends in the recess 11. Through the slot 14, a tongue 15 is created with the same width as the recess and the spiral-shaped projection 10, which yields under pressure due to the nose 12 and the spiral projection 10. Once the nose 12 and the helical projection 10 is completely in the recess 11, the tongue 15 clicks back to its original position.

FIG. 3 zeigt eine Ausführungsform einer Steckverbindungsanordnung. Ein Steckerkörper 16 unterscheidet sich von dem Steckerkörper 1 gemäß des Beispiels durch das Steckelement 17. Das Steckelement 17 hat vorzugsweise eine rechteckige Grundfläche und weist ein ebenfalls rechteckiges Stützelement 18 auf, das auf einer im Schnitt dargestellten Wand 19 aufliegt. Das Steckelement 17 ist in eine Öffnung in der Wand 19 eingesteckt und nicht eingedreht und liegt an dem Rand der Öffnung an, die an die rechteckige Form des Steckelements 17 angepaßt ist, d.h. ebenfalls rechteckig ist. Aufgrund seines rechteckigen Querschnitts ist das Steckelement 19 nicht nur fest in der Öffnung positioniert, sondern kann auch nicht verdreht werden. Der Querschnitt kann aber auch kreisförmig sein, wie mit Bezugnahme auf FIG. 5 noch erläutert wird. FIG. 3 shows an embodiment of a connector assembly. A plug body 16 differs from the plug body 1 according to the example by the plug element 17. The plug element 17 preferably has a rectangular base and has a likewise rectangular support member 18 which rests on a wall 19 shown in section. The plug element 17 is in an opening inserted in the wall 19 and not screwed and abuts the edge of the opening, which is adapted to the rectangular shape of the male member 17, that is also rectangular. Due to its rectangular cross-section, the plug-in element 19 is not only fixedly positioned in the opening, but also can not be twisted. The cross section may also be circular, as with reference to FIG. 5 will be explained.

Parallel zur Wand 19 verläuft am Einsteckelement 17 eine Ausnehmung 21. Diese kann mitten durch das Steckelement 17 verlaufen, wird vorzugsweise jedoch an dessen Rand ausgebildet sein, wo keine elektrischen Leitungen 4 verlaufen. Die Aussparung 21 ist dabei so positioniert, daß ohne eine Krafteinwirkung, durch welche eine Dichtung 20, die zwischen der Wand 19 und dem Stützelement 18 verläuft und am Stützelement 18 befestigt ist, zusammengedrückt wird, sich die Ausnehmung 21 nicht bündig an die Wand 19 anschließt, sondern eine Stufe zwischen der Wand 19 und der Ausnehmung 21 ausgebildet ist.Parallel to the wall 19 extends on the male member 17 has a recess 21. This may extend through the middle of the plug 17, but will preferably be formed at the edge where no electrical lines 4 extend. The recess 21 is positioned so that without a force through which a seal 20 which extends between the wall 19 and the support member 18 and is secured to the support member 18 is compressed, the recess 21 is not flush with the wall 19 but a step between the wall 19 and the recess 21 is formed.

FIG. 4 zeigt den Stecker aus FIG. 3 von einer anderen Seite. Der Stecker weist mehrere elektrische Leitungen 4 auf, die von der Halterungsausnehmung 6 und zu den Kontakten 5 unten am Steckelement 17 verlaufen. FIG. 4 shows the plug FIG. 3 from another side. The plug has a plurality of electrical lines 4, which extend from the Halterungsausnehmung 6 and the contacts 5 below the plug-in element 17.

FIG. 5 zeigt die Steckverbindungsanordnung aus Fig. 3, wobei der Stecker 16 durch das Einschieben eines Riegelelements 22 in die Ausnehmung 21 in einer Öffnung befestigt ist. Vorne an dem Riegelelement 22 ist eine keilförmige Spitze 23 ausgebildet. Wenn das Riegelelement 22 in die Ausnehmung 21 eingeschoben wird, stößt die keilförmige Spitze 23 gegen die untere Kante der Ausnehmung 21. Dadurch wird eine Kraft auf die Dichtung 20 ausgeübt, die zusammengepreßt wird. Der Stecker 16 liegt daher fest und dicht an der Wand 19 an, was für einen Scheibenwischermotor wichtig ist. Das Riegelelement 22 verhindert zusätzlich eine Drehung des Steckers, falls für diesen einen ein kreisförmiger Querschnitt gewählt wurde. In der zweiten Ausführungsform bedeutet das Ineinandergreifen des Steckelements 17 und des Riegelelements 22 also konkret, daß das Riegelelement 22 in eine Ausnehmung 21 eingeschoben ist. Das Riegelelement 22, an dem beliebige elektrische Bauteile 24, wie Kondensatoren 24 angebracht sein können, besteht vorzugsweise aus Kunststoff. Es kann sich aber auf um ein einfaches Federelement handeln, wenn eine solche Sicherung zum Beispiel aufgrund der rechteckigen Ausgestaltung des Einsteckelements 17 ausreichend ist. FIG. 5 shows the connector assembly Fig. 3 wherein the plug 16 is secured by the insertion of a locking element 22 in the recess 21 in an opening. At the front of the locking element 22, a wedge-shaped tip 23 is formed. When the locking element 22 is inserted into the recess 21, the wedge-shaped tip 23 abuts against the lower edge of the recess 21. Thereby, a force is exerted on the seal 20, which is compressed. The plug 16 is therefore fixed and close to the wall 19, which is important for a windscreen wiper motor. The locking element 22 additionally prevents rotation of the plug, if a circular cross section was selected for this one. In the second embodiment, the engagement of the plug element 17 and the locking element 22 thus means concretely that the locking element 22 is inserted into a recess 21. The locking element 22, on which any electrical components 24, such as capacitors 24 may be attached, is preferably made of plastic. However, it can be a simple spring element, if such a fuse is sufficient, for example due to the rectangular configuration of the male element 17.

Eine elektrische Verbindung wird gemäß der Ausführungsform dadurch hergestellt, daß die Kontakte 5 gegen als Federelemente ausgebildete Enden der internen elektrischen Leitungen drücken. Die internen elektrischen Leitungen können mit den Kontakten aber auch verlötet werden.An electrical connection is made in accordance with the embodiment in that the contacts 5 press against designed as spring elements ends of the internal electrical wires. The internal electrical leads can also be soldered to the contacts.
