Description

Die Erfindung betrifft eine Verriegelungsvorrichtung zur reversiblen Verriegelung eines Steckverbindergehäuses mit einem dafür vorgesehenen Gegensteckergehäuse nach dem Oberbegriff des Anspruchs 1.The invention relates to a locking device for the reversible locking of a connector housing with a mating connector housing provided according to the preamble of claim 1.

Steckverbindergehäuse tragen in der Regel jeweils mehrere Kontaktelemente, die beispielsweise mit den einzelnen Leitern eines angeschlossenen Kabels verbunden sind. Die Kontaktelemente des Steckverbindergehäuses werden mit den Kontaktelementen eines dazu passenden Gegensteckers kontaktiert. Die Kontaktelemente sind dazu steckseitig stift- oder buchsenförmig ausgebildet. Verriegelungsvorrichtungen werden benötigt, damit die miteinander kontaktierten Kontaktelemente des Steckverbinders und Gegensteckers nicht aus Versehen, beispielsweise durch einen leichten Zug am Kabel, wieder voneinander gelöst werden können.Connector housings usually carry a plurality of contact elements, which are connected for example to the individual conductors of a connected cable. The contact elements of the connector housing are contacted with the contact elements of a matching mating connector. The contact elements are on the plug-pin side or socket-shaped. Locking devices are needed so that the contacted contact elements of the connector and mating connector can not be accidentally released from each other by mistake, for example by a slight pull on the cable.

Die DE 195 08 605 C1 zeigt ein Steckverbindergehäuse welches beidseitig schwenkbar gelagerte, U-förmige Verriegelungsbügel aufweist. Die Verriegelungsbügel umfassen kipphebelartige Verriegelungselemente, die beim Verriegelungsvorgang über Zapfen eines Gegensteckergehäuses geführt werden. Diese Steckverbindergehäuseverriegelung ist unter dem Markennamen Han-easy-lock® bekannt.
Eine Steckverbindung, die über Verriegelungsbügel gesichert ist, gilt als sehr zuverlässig. Fällt ein Steckverbindergehäuse, welches derartige Verriegelungsbügel umfasst, jedoch auf den Boden, können die Verriegelungsbügel verbogen oder die Lagerung der Bügel beschädigt werden. Dadurch wird die Zuverlässigkeit einer solchen Verriegelung vermindert. Außerdem lässt die Dichtwirkung zwischen den Steckverbindergehäusen nach.The DE 195 08 605 C1 shows a connector housing which has pivotally mounted on both sides, U-shaped locking bracket. The locking brackets comprise rocker-type locking elements which are guided over pins of a mating connector housing during the locking process. This connector housing interlock is known under the brand name Han-easy-lock® .
A connector that is secured by locking brackets is considered very reliable. Falls a connector housing, which includes such locking bracket, but on the ground, the Locking bar bent or the storage of the straps damaged. This reduces the reliability of such a lock. In addition, the sealing effect between the connector housings decreases.

Die DE 197 54 528 A1 zeigt eine Verriegelungsvorrichtung zur Verbindung von zwei zusammengesteckten Steckverbindern. An einer Grundform stehen senkrecht Verriegelungsarmpaare ab, die jeweils Einführungsausschnitte aufweisen. Die Steckverbinder weisen jeweils Zapfen auf, die mit den Einführungsabschnitten der Verriegelungsvorrichtung zur reversiblen Verbindung zusammenwirken. Eine solche Verriegelungsvorrichtung kann ebenfalls durch Herabfallen erheblich beschädigt werden.The DE 197 54 528 A1 shows a locking device for connecting two mated connectors. On a basic form are perpendicular from Verriegelungsarmpaare, each having insertion cutouts. The connectors each have pins which cooperate with the insertion portions of the locking device for reversible connection. Such a locking device can also be significantly damaged by falling.

Die DE1852077U offenbart einen Stecker, der über eine Gummilasche reversibel in einer Steckdose fixiert werden kann. Die Gummilasche ist länglich und flach geformt und enthält endseitig zwei Löcher, die jeweils mit Zapfen der Steckdose und des Steckers zusammenwirken. Die US 3,163,481 A zeigt ein vergleichbares Prinzip. Hier wird die Gummilasche endseitig jedoch mit metallischen Clips versehen, die die Seitenwände der Steckdose umgreifen.The DE1852077U discloses a plug that can be reversibly fixed in a socket via a rubber strap. The rubber strap is elongated and flat shaped and contains two holes at the end, each of which interacts with pins of the socket and the plug. The US 3,163,481 A shows a similar principle. Here, however, the rubber strap end is provided with metallic clips that surround the side walls of the socket.

Die WO 2011069521 A1 zeigt ein Steckverbindergehäuse, welches über zwei Druckknöpfe verfügt. Die Druckknöpfe sind mit im Gehäuseinneren befindlichen Blechen wirkverbunden, die eine Ausnehmung enthalten, die über einen Rastfortsatz des jeweils passenden Gegensteckergehäuses greift. Dieser Steckverbinder samt Verriegelung ist im Markt unter dem Namen Han-Yellock® bekannt.The WO 2011069521 A1 shows a connector housing, which has two push buttons. The push buttons are operatively connected to sheets located inside the housing, which contain a recess which engages over a latching extension of the respective mating connector housing. This connector and lock is known in the market under the name Han-Yellock® .

Eine derartige Verriegelung ist sehr zuverlässig und auch gegen mechanische Einwirkungen (Herabfallen, Draufhauen, etc.) gewappnet. Allerdings hat eine derartige Verriegelung einen höheren Preis als eine Verriegelung, die über Verriegelungsbügel realisiert wird.Such a lock is very reliable and also against mechanical effects (falling, throwing around, etc.) armed. However, such a lock has a higher price than a lock which is realized via locking bracket.

Die Aufgabe der Erfindung besteht darin, eine Verriegelungsvorrichtung für miteinander zusammensteckbare Steckverbindergehäuse vorzuschlagen, die robust und preisgünstig ist. Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object of the invention is to propose a locking device for plug-together connector housing, which is robust and inexpensive. The object is solved by the characterizing features of claim 1.

Die erfindungsgemäße Verriegelungsvorrichtung ist zur reversiblen Verriegelung eines Steckverbindergehäuses mit einem dazu passenden Gegensteckergehäuse vorgesehen. Es ist aber auch denkbar die Verriegelungsvorrichtung zum Verriegeln eines Steckverbindergehäuses bei einer Maschinenbuchse zu verwenden.The locking device according to the invention is provided for the reversible locking of a connector housing with a matching mating connector housing. But it is also conceivable to use the locking device for locking a connector housing in a machine bushing.

Im Folgenden werden ein Steckverbindergehäuse und Gegensteckergehäuse auch kurz als Gehäuse bezeichnet. Dies ist insbesondere dann der Fall, wenn sich Merkmale gleichwertig auf beide (Steckverbindergehäuse und Gegensteckergehäuse) übertragen lassen.Hereinafter, a connector housing and mating connector housing are also referred to as housing for short. This is especially the case when features equivalent to both (connector housing and mating connector housing) can be transferred.

Im Inneren des Steckverbindergehäuses sind Kontaktelemente angeordnet, die jeweils mit den einzelnen Leitern eines angeschlossenen Kabels verbunden sind. Mehrere einzelne Kontaktelemente werden oft auch in so genannten Steckverbindermodulen zusammengefasst, wie sie beispielsweise in der WO 2011069521 A1 offenbart sind. Die Module können dann als Ganzes in die Steckverbindergehäuse eingebracht werden.Inside the connector housing contact elements are arranged, which are each connected to the individual conductors of a connected cable. Several individual contact elements are often combined in so-called connector modules, as for example in the WO 2011069521 A1 are disclosed. The modules can then be inserted as a whole in the connector housing.

Die Verriegelungsvorrichtung umfasst zumindest ein Verriegelungsarmpaar. Das Verriegelungsarmpaar besteht aus zwei einzelnen Verriegelungsarmen, die in entgegengesetzter Richtung zueinander vom Grundkörper der Verriegelungsvorrichtung abstehen. Endseitig umfassen die einzelnen Verriegelungsarme Aufnahmen. In diese Aufnahmen können die an den jeweiligen Steckverbindergehäusen angeformten Lagerzapfen eingreifen, so dass die beiden Steckverbindergehäuse (Stecker und Gegenstecker) miteinander verriegelt sind. Verriegelt bedeutet in diesem Fall, dass das Steckverbindergehäuse und das Gegensteckergehäuse federnd gegeneinander gepresst sind.The locking device comprises at least one pair of locking arms. The locking arm pair consists of two individual locking arms, which protrude in the opposite direction to each other from the main body of the locking device. At the end, the individual locking arms comprise receptacles. In this recording, the formed on the respective connector housing bearing pin can engage, so that the two connector housings (plug and mating connector) are locked together. Locked in this case means that Connector housing and the mating connector housing are resiliently pressed against each other.

Ein federndes Gegeneinanderpressen zweier miteinander zusammengesteckter Gehäuse wird dadurch realisiert, dass die Verriegelungsarme der Verriegelungsvorrichtung in axialer Richtung dehnbar sind. Daher bestehen die Verriegelungsarme der Verriegelungsvorrichtung aus einem elastomeren Werkstoff, beispielsweise Nitrilkautschuk (NBR, HNBR), Ethylen-Propylen-Dien-Kautschuk (EPDM), Polyurethan oder aus einer Kombination der vorgenannten Materialien. Vorzugsweise wird der elastomere Werkstoff zusätzlich noch faserverstärkt. Dadurch wird eine besonders langlebige Verriegelungsvorrichtung erreicht. In der Regel werden die zusammen gesteckten Steckverbindergehäuse durch ein Dichtelement gegen das Eindringen von Medien abgedichtet. Erfindungsgemäß ist das Dichtelement ein Teil der Verriegelungsvorrichtung. Das Dichtelement wird im Wesentlichen vom Grundkörper der Verriegelungsvorrichtung gebildet und ist demnach an die Bauform der Steckverbindergehäuse angepasst. Vom Grundkörper steht das zumindest eine Verriegelungsarmpaar ab, so dass Dichtelement und Verriegelungsvorrichtung als einstückiges Bauteil ausgebildet sind.A resilient pressing against each other two mutually mated housing is realized in that the locking arms of the locking device are stretchable in the axial direction. Therefore, the locking arms of the locking device made of an elastomeric material, such as nitrile rubber (NBR, HNBR), ethylene-propylene-diene rubber (EPDM), polyurethane or a combination of the aforementioned materials. Preferably, the elastomeric material is additionally fiber-reinforced. As a result, a particularly durable locking device is achieved. In general, the plugged together connector housing are sealed by a sealing element against the ingress of media. According to the invention, the sealing element is a part of the locking device. The sealing element is essentially formed by the main body of the locking device and is therefore adapted to the design of the connector housing. From the main body is the at least one Verriegelungsarmpaar so that sealing element and locking device are formed as a one-piece component.

Der Grundkörper kann auch als Verriegelungsring bezeichnet werden. Der Verriegelungsring ist zwischen die Fügenaht des Steckverbindergehäuses und des Gegensteckergehäuses klemmbar und dichtet diese dadurch ab. Erfindungsgemäß ist am Verriegelungsring zumindest ein Verriegelungsarm angeformt. Vorteilhafterweise sind am Verriegelungsring mehrere Verriegelungsarme angeformt.The main body can also be referred to as a locking ring. The locking ring is clamped between the joining seam of the connector housing and the mating connector housing, thereby sealing them. According to the invention, at least one locking arm is formed on the locking ring. Advantageously, a plurality of locking arms are integrally formed on the locking ring.

Vorteilhafterweise hat der elastomere Werkstoff, aus dem die Verriegelungsvorrichtung gebildet ist, eine Härte zwischen 90 und 30 Shore-B. Es kann aber auch vorteilhaft sein, wenn der elastomere Werkstoff, aus dem die Verriegelungsvorrichtung gebildet ist, eine Härte zwischen 90 und 30 Shore-A besitzt.Advantageously, the elastomeric material of which the locking device is formed has a hardness between 90 and 30 Shore-B. However, it may also be advantageous if the elastomeric material of which the locking device is formed has a hardness between 90 and 30 Shore A.

Test haben gezeigt, dass eine Shorehärte zwischen 60 und 70 Shore-A besonders vorteilhaft ist. In diesem Fall lassen sich die Verriegelungsarme vom Nutzer händisch wieder von den Lagerzapfen der Steckverbindergehäuse entfernen, ohne dass die Verriegelungsstärke und die Dichtigkeit verringert ist.Tests have shown that a Shore hardness between 60 and 70 Shore A is particularly advantageous. In this case, the user can manually remove the locking arms from the pins of the connector housings without reducing the locking strength and the tightness.

Bei den Aufnahmen der Verriegelungsarme wird es sich in der Regel um Bohrungen handeln, die über die Lagerzapfen der Steckverbindergehäuse geführt sind. In einer vorteilhaften Ausführungsform der Erfindung umfassen die Aufnahmen eine metallische Komponente durch die diese verstärkt werden. Beispielsweise kann es sich bei der metallischen Komponente um eine Öse handeln, die den Rand der Aufnahme des Verriegelungsarms umschließt. Dadurch wird die erfindungsgemäße Verriegelungsvorrichtung besonders haltbar und langlebig.When shooting the locking arms will usually be holes that are guided over the journals of the connector housing. In an advantageous embodiment of the invention, the receptacles comprise a metallic component by which they are reinforced. For example, the metallic component may be an eyelet that encloses the edge of the receptacle of the locking arm. As a result, the locking device according to the invention is particularly durable and durable.

Anstatt einer metallischen Komponente können die Aufnahmen auch durch eine Kunststoffkomponente verstärkt werden. Diese Kunststoffverstärkung kann direkt beim Herstellungsprozess mit in die Verriegelungsvorrichtung einvulkanisiert oder eingespritzt werden.Instead of a metallic component, the recordings can also be reinforced by a plastic component. This plastic reinforcement can be directly vulcanized or injected into the locking device during the manufacturing process.

In einer besonders bevorzugten Ausführungsform der Erfindung wird zumindest ein Verriegelungsarm der Verriegelungsvorrichtung irreversibel an ein Steckverbindergehäuse angebracht. Dies kann beispielsweise über eine Nietverbindung realisiert werden. Beim Nietvorgang wird die Niete durch die Aufnahmen des Verriegelungsarms und gleichzeitig durch eine dazu passende Bohrung im Gehäuse geführt. Anschließend wird der Nietkopf irreversibel mit einem geeigneten Werkzeug verformt. In diesem Fall ist die Verriegelungsvorrichtung verliersicher mit einem Steckverbindergehäuse verbunden.In a particularly preferred embodiment of the invention, at least one locking arm of the locking device is irreversibly attached to a connector housing. This can be realized for example via a riveted joint. When riveting the rivet is guided by the recordings of the locking arm and at the same time through a matching hole in the housing. Subsequently, the rivet head is irreversibly deformed with a suitable tool. In this case, the Locking device connected captive with a connector housing.

Eine Irreversible Anbringung der Verriegelungsvorrichtung an ein Steckverbindergehäuse kann auch über eine Klebung erreicht werden. Es ist auch denkbar die Verriegelungsvorrichtung direkt an das Steckverbindergehäuse anzuvulkanisieren, insbesondere dann, wenn es sich um ein Kunststoffgehäuse handelt.An irreversible attachment of the locking device to a connector housing can also be achieved via an adhesive bond. It is also conceivable to vulcanize the locking device directly to the connector housing, especially if it is a plastic housing.

In einer besonders bevorzugten Ausführungsform der Erfindung besitzt die Verriegelungsvorrichtung lediglich einen Verriegelungsarm, der am Grundkörper angeformt ist und von diesem Grundkörper in entgegengesetzter Richtung absteht. Der Grundkörper ist beispielsweise an einem Gehäuse befestigt (beispielsweise geklebt). Der Verriegelungsarm greift an dem anderen Gehäuse an und verriegelt so beide Gehäuse miteinander.In a particularly preferred embodiment of the invention, the locking device has only one locking arm, which is integrally formed on the base body and protrudes from this base body in the opposite direction. The main body is attached to a housing (for example, glued), for example. The lock arm engages the other housing, locking both housings together.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Die Figur 1 zeigt eine perspektivische Darstellung eines mit einem Steckverbindergehäuse 1 verriegelten Gegensteckergehäuse 2. Bei dem Steckverbindergehäuse 1 und Gegensteckergehäuse 2 handelt es sich um ein seit vielen Jahren im Markt erhältliches Bauteil. Hier sind Steckverbindergehäuse 1 und Gegensteckergehäuse 2 baulich gleich ausgeführt. Dies ist aber nicht immer der Fall. Das Steckverbindergehäuse 1 enthält eine Öffnung 3 durch welche das anzuschließende Kabel (hier nicht gezeigt) ins Innere der Steckverbindergehäuses 1 ragt. An den Längsseiten des Steckverbindergehäuses 1 sind Lagerzapfen 18 angeformt.The FIG. 1 shows a perspective view of a locked with a connector housing 1 mating connector 2. The connector housing 1 and mating connector 2 is a available for many years on the market component. Here are connector housing 1 and mating connector 2 structurally the same. This is not always the case. The connector housing 1 includes an opening 3 through which the cable to be connected (not shown here) projects into the interior of the connector housing 1. On the longitudinal sides of the connector housing 1 bearing pin 18 are formed.

Die Figur 2 zeigt eine perspektivische Darstellung der Verriegelungsvorrichtung 9. Die Verriegelungsvorrichtung 9 hat einen im Wesentlichen rechteckigen Grundkörper 11. Innerhalb des Grundkörpers 11 ist ein umlaufender Steg 12 vorgesehen, der mit der Gehäusekante des Steckverbinders 1 korreliert. Der Steg 12 befindet sich auf beiden Seiten des Grundkörpers 11. Dadurch werden zwei miteinander verriegelte Steckverbindergehäuse 1, 2 (Stecker- und Gegensteckergehäuse) gegen Medien wie beispielsweise Staub und Wasser abdichtet. Der Grundkörper 11 wird auch als Verriegelungsring bezeichnet.The FIG. 2 shows a perspective view of the locking device 9. The locking device 9 has a substantially rectangular base body 11. Within the base body 11, a circumferential ridge 12 is provided, which correlates with the housing edge of the connector 1. The web 12 is located on both sides of the base body 11. As a result, two mutually locked connector housing 1, 2 (plug and mating connector housing) against media such as dust and water seals. The main body 11 is also referred to as a locking ring.

Vom Grundkörper 11 der Verriegelungsvorrichtung 9 stehen senkrecht Verriegelungsarme 15, 20 in beiden Richtungen ab. Die gegensinnig abstehenden einzelnen Verriegelungsarme 15, 20 bilden zusammen ein Verriegelungsarmpaar 10. Jeder Verriegelungsarme 15, 20 enthält Aufnahmen 16, 17, die die Lagerzapfen 18 der Gehäuse 1, 2 umgreifen.From the main body 11 of the locking device 9 are perpendicular locking arms 15, 20 in both directions. The oppositely projecting individual locking arms 15, 20 together form a Verriegelungsarmpaar 10. Each locking arms 15, 20 includes receptacles 16, 17 which engage around the bearing pin 18 of the housing 1, 2.

Die Höhendifferenz zwischen den Aufnahmen 16, 17 der Verriegelungsarme 15, 20 und der Ebene des umlaufenden Stegs 12 ist geringer als die Höhendifferenz zwischen den Lagerzapfen 18 und der auf den Steg 12 aufliegenden unteren Kante des Steckverbindergehäuses 1. Da die Verriegelungsarme 15, 20 aus einem elastischen Material (einem Elastomer) gebildet sind, wird eine Zugkraft in axialer Richtung auf die Lagerzapfen 18 ausgeübt und die untere Kante des Steckverbindergehäuses 1 auf den Steg 12 gepresst. Dadurch wird mit der Verriegelungsvorrichtung gleichzeitig auch eine optimale Dichtfunktion erreicht.The height difference between the receptacles 16, 17 of the locking arms 15, 20 and the plane of the circumferential web 12 is less than the height difference between the journals 18 and resting on the web 12 lower edge of the connector housing 1. Since the locking arms 15, 20 are formed of an elastic material (an elastomer), a tensile force is exerted in the axial direction of the bearing pin 18 and the lower edge of the connector housing 1 is pressed onto the web 12. As a result, an optimal sealing function is achieved at the same time with the locking device.

Die Verriegelungsarme 15, 20 sind innenseitig mit einer schrägen Kante 13 versehen. Dadurch liegen die Verriegelungsarme im oberen Bereich nicht direkt am Steckverbindergehäuse 1 und Gegensteckergehäuse 2 an. So können die Verriegelungsarme 15, 20 händisch wieder leicht von den Lagerzapfen 18 entfernt werden. Beim Verriegelungsvorgang sorgt die abgeschrägte Kante 13 dafür, dass die Verriegelungsarme 15, 20 zunächst über die Gehäusekante und die Lagerzapfen 18 hinweggleiten. Anschließend klappen die Verriegelungsarme 15, 20 über die Lagerzapfen 18 ein, so dass sich die Lagerzapfen 18 in den zugehörigen Aufnahmen 16, 17 befinden. Ein derartiger Verriegelungsvorgang erfordert lediglich einen geringen Kraftaufwand.The locking arms 15, 20 are provided on the inside with an oblique edge 13. As a result, the locking arms are not directly on the connector housing 1 and mating connector housing 2 in the upper area. Thus, the locking arms 15, 20 manually again easily removed from the journals 18. During the locking process, the chamfered edge 13 ensures that the locking arms 15, 20 first slide over the housing edge and the bearing journals 18. Subsequently, the locking arms 15, 20 fold over the bearing pin 18, so that the bearing pin 18 in the associated receptacles 16, 17 are. Such a locking process requires only a small amount of force.

Lässt die Zugkraft der elastomeren Verriegelungsarme 15, 20 nach, kann ein Kunde die Steckverbindergehäuse 1, 2 weiterverwenden und einfach eine neue, frische Verriegelungsvorrichtung 9 anbringen. Die erfindungsgemäße Verriegelungsvorrichtung 9 kann bei geeigneter Materialwahl als recyclefähiges Einwegteil vorgesehen sein. So bleibt die Dicht- und Verriegelungswirkung bei einem erneuten Zusammenstecken der Gehäuse 1, 2 immer auf dem gleichen Niveau.If the tensile force of the elastomeric locking arms 15, 20 decreases, a customer can continue to use the connector housings 1, 2 and simply attach a new, fresh locking device 9. The locking device 9 according to the invention can be provided with a suitable choice of material as recyclable disposable part. Thus, the sealing and locking effect remains at a renewed mating of the housing 1, 2 always at the same level.

Die Figur 3 zeigt eine weitere Ausführungsform einer erfindungsgemäßen Verriegelungsvorrichtung 9'. Bauteile mit der gleichen Funktion werden auch mit den oben bereits verwendeten Bezugszeichen versehen. Um einen Unterschied zwischen den einzelnen Ausführungsformen aufzuzeigen, werden die Bezugszeichen jedoch mit einen " ' " versehen.The FIG. 3 shows a further embodiment of a locking device 9 'according to the invention. Components with the same function are also provided with the reference numerals already used above. Around to show a difference between the individual embodiments, the reference numerals are, however, provided with a "'".

Die Verriegelungsarme 15' der Verriegelungsvorrichtung 9' werden über Nieten 4 am Steckverbindergehäuse 1 befestigt. An Stelle von Nieten kann aber auch eine Schraubverbindung vorgesehen sein. Der Verriegelungsarm 20' ist einteilig ausgebildet und enthält zwei Aufnahmen 17', die über die Zapfen 18 des Gegensteckergehäuses 2 greifen.The locking arms 15 'of the locking device 9' are fastened via rivets 4 on the connector housing 1. Instead of rivets but also a screw connection can be provided. The locking arm 20 'is integrally formed and includes two receptacles 17', which engage over the pins 18 of the mating connector housing 2.

Im Markt sind Gehäuse erhältlich, die Zapfen 18 auf der Längsseite oder auch auf der Schmalseite tragen. Bei Gegensteckergehäusen 2 mit Zapfen 18 an den Schmalseiten, ist der Verriegelungsarm 20' an der Schmalseite des Grundkörpers 11' der Verriegelungsvorrichtung 9' angebracht. Befinden sich die Zapfen an der Längsseite des Steckverbindergehäuses 1, können die Verriegelungsarme 15', 20' an unterschiedlichen Stellen (Längsseite, Schmalseite) vom Grundkörper 11' der Verriegelungsvorrichtung 9' abstehen. Es ist also möglich mit der erfindungsgemäßen Verriegelungsvorrichtung 9' Gehäuse 1, 2 miteinander zu verriegeln, deren Zapfen 18 unterschiedlich zueinander ausgerichtet sind. Dies war mit den bekannten Verriegelungsvorrichtungen bislang nicht möglich.Housings are available in the market, the pins carry 18 on the long side or on the narrow side. In mating connector housings 2 with pin 18 on the narrow sides, the locking arm 20 'on the narrow side of the main body 11' of the locking device 9 'is mounted. Are the pins on the longitudinal side of the connector housing 1, the locking arms 15 ', 20' at different locations (longitudinal side, narrow side) from the main body 11 'of the locking device 9' protrude. It is therefore possible with the locking device according to the invention 9 'housing 1, 2 lock together, the pins 18 are aligned differently. This was previously not possible with the known locking devices.

Die Figur 5 zeigt eine perspektivische Darstellung einer dritten Ausführungsform der Verriegelungsvorrichtung 9". Auch bei dieser Ausführungsform werden die Verriegelungsarme 15" bevorzugt über eine Niet- oder Schraubverbindung an das Steckverbindergehäuse 1 angebracht.The FIG. 5 shows a perspective view of a third embodiment of the locking device 9 ". Also in this embodiment, the locking arms 15" are preferably attached to the connector housing 1 via a rivet or screw connection.

Die Verriegelungsarme 20" werden - wie bereits bei den anderen Ausführungsformen beschrieben - über die Lagerzapfen 18 des Gegensteckergehäuses 2 geführt. Dadurch werden die Gehäuse 1, 2 miteinander verriegelt. Auch bei dieser Ausführungsform können die Verriegelungsarme 15", 20" so am Grundkörper 11" angebracht werden, das verschiedene Gehäusetypen mit unterschiedlicher Lagerzapfenposition miteinander verriegelbar sind. Diese Eigenschaft macht die erfindungsgemäßen Verriegelungsvorrichtungen 9, 9', 9" zu flexibel und universell einsetzbar.The locking arms 20 "are - as already described in the other embodiments - guided over the bearing pin 18 of the mating connector housing 2. This locks the housings 1, 2. In this embodiment too, the locking arms 15", 20 "can be attached to the main body 11". be attached the different types of housing with different journal position can be locked together.
