Description

Schutzvorrichtung für eine SteckverbindungProtection device for a plug connection
Die Erfindung betrifft eine Schutzvorrichtung für eine Steckverbindung gemäss dem Oberbegriff von Anspruch 1.The invention relates to a protective device for a plug connection according to the preamble of claim 1.
Es ist eine Vielzahl modular ausgestalteterIt is a multitude of modular ones
SteckverbindungsSysteme bekannt, um beispielsweise Telefonleitungen, Computersysteme oder Netzwerke miteinander zu verbinden. So ist beispielsweise die RJ45- Steckverbindung ein nach IEC 60603-7 genormter und weltweit angewandter Standard für Steckverbinder in Kommunikations- und Datennetzen. Eine derartige Steckverbindung umfasst einen Stecker sowie eine Steckbuchse. Die Steckbuchse ist üblicherweise in einer Steckdose, einem Rack, oder einem sogenannten Rangierfeld angeordnet .Connector systems are known, for example to connect telephone lines, computer systems or networks. For example, the RJ45 connector is a standard for connectors in communication and data networks that is standardized and used worldwide in accordance with IEC 60603-7. Such a plug connection comprises a plug and a socket. The socket is usually arranged in a socket, a rack, or a so-called patch panel.
Modern ausgerüstete Gebäude weisen heute eine sogenannte Universelle Gebäudeverkabelung (UGV) mit einer Vielzahl von Steckbuchsen auf, um je nach Bedarf analoge oder digitale Telefone, Telefax-Geräte, Computer, Drucker und Modems miteinander zu verbinden. Dabei ist das Ethernet TCP/IP von besonderer Bedeutung, welches sich immer mehr als herstellerunabhängiger und kostengünstiger Standard im Bürobereich und in der Automatisierungstechnik durchsetzt.Modernly equipped buildings today have a so-called universal building wiring system (UGV) with a large number of sockets to connect analog or digital telephones, fax machines, computers, printers and modems with one another as required. The Ethernet TCP / IP is of particular importance, which is becoming more and more established as a manufacturer-independent and inexpensive standard in the office area and in automation technology.
Nachteilig an diesen bekannten Steckverbindungen ist die Tatsache, dass sie für industrielle Anwendungen kaum geeignet sind, da eine sichere Netzwerkfunktion unter schwierigen Umweltbedingungen, wie diese in der Industrie auftreten, nicht gewährleistet ist. So können bekannte Steckverbindungen basierend auf dem RJ45- Steckverbindersystem eine Schutzklasse, wie die IP 67 (gemäss Norm IEC 60529) nicht erfüllen, was bedeutet, dass die an sich sehr weit verbreitete und kostengünstige RJ45- Steckverbindung im industriellen Umfeld nicht verwendet werden kann, weil Ausseneinwirkungen wie Vibrationen oder Beeinträchtigungen durch Kühlflüssigkeiten oderA disadvantage of these known plug connections is the fact that they are hardly suitable for industrial applications, since a reliable network function cannot be guaranteed under difficult environmental conditions, such as those which occur in industry. Known plug-in connections based on the RJ45 plug-in connector system can have a protection class such as IP 67 (according to IEC 60529 standard), which means that the very widespread and inexpensive RJ45 connector cannot be used in an industrial environment because of external influences such as vibrations or impairments caused by coolants or
Lösungsmittel, Oel und dergleichen, auftreten, und/oder Schmutz und/oder Staub deren Anwendung verhindert.Solvents, oils and the like occur, and / or dirt and / or dust prevents their use.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Schutzvorrichtung für eine Steckverbindung zu bilden, welche den Einsatz bekannter Steckverbindungen in einem breiteren Einsatzgebiet ermöglicht.It is therefore an object of the present invention to form a protective device for a plug connection, which enables the use of known plug connections in a wider area of application.
Diese Aufgabe wird gelöst mit einer Schutzvorrichtung für eine Steckverbindung aufweisend die Merkmale von Anspruch 1. Die abhängigen Ansprüche 2 bis 14 betreffen vorteilhaft ausgestaltete Weiterbildungen dieser Schutzvorrichtung.This object is achieved with a protective device for a plug connection having the features of claim 1. The dependent claims 2 to 14 relate to advantageous developments of this protective device.
Die Aufgabe wird insbesondere gelöst mit einer Schutzvorrichtung umfassend ein Ankopplungsteil sowie ein Steckergehäuse für einen darin anzuordnenden Stecker, wobei das Ankopplungsteil eine Öffnung für den Stecker aufweist, und wobei die Öffnung von einem vorstehenden, insbesondere um 360 Grad umlaufenden, Kragen umgeben ist, wobei der Kragen eine umlaufende Nut aufweist, und wobei das Steckergehäuse ein bezüglich der Nut angepasst ausgestaltetes Einrastteil umfasst, um das Steckergehäuse mit Hilfe des in die Nut eingreifenden Einrastteils mit dem Ankopplungsteil zu verbinden.The object is achieved in particular with a protective device comprising a coupling part and a plug housing for a plug to be arranged therein, the coupling part having an opening for the plug, and the opening being surrounded by a protruding collar, in particular a 360-degree circumference, the Collar has a circumferential groove, and wherein the plug housing comprises a snap-in part adapted in relation to the groove, in order to connect the plug housing to the coupling part with the aid of the snap-in part engaging in the groove.
In einer bevorzugten Ausführungsform ist der Stecker als RJ45-Stecker ausgestaltet, wobei der Stecker beispielsweise auch als Lichtwellenleiter-Stecker oder als Universal-Serial-Bus-Stecker, auch als USB-Stecker bezeichnet, ausgestaltet sein kann. Die Schutzvorrichtung ermöglicht eine wasserdichte und/oder staubdichte Verbindung des Steckergehäuses mit dem Ankopplungsteil .In a preferred embodiment, the plug is designed as an RJ45 plug, and the plug can also be designed, for example, as an optical waveguide plug or as a universal serial bus plug, also referred to as a USB plug. The protective device enables a watertight and / or dustproof connection of the plug housing to the coupling part.
Das Ankopplungsteil kann als ein Bestandteil der Buchse ausgestaltet sein. In einer besonders vorteilhaften Ausführungsform ist das Ankopplungsteil jedoch flanschförmig ausgestaltet. Dieses flanschförmige Ankopplungsteil wird bevorzugt wasserdicht und/oder schmutz- und staubdicht vor der Buchse montiert. Die erfindungsgemässe Schutzvorrichtung ermöglicht somit den Stecker, insbesondere den RJ45-Stecker, sicher und unter Einhaltung der Schutzklasse IP 67 mit der Buchse zu verbinden. Das flanschförmige Ankopplungsteil ist beispielsweise aus Metall oder einem Kunststoff gefertigt. Dieses flanschförmige Ankopplungsteil weist zudem denThe coupling part can be designed as a component of the socket. In a particularly advantageous embodiment, however, the coupling part is designed in the form of a flange. This flange-shaped coupling part is preferably installed in a watertight and / or dirt and dustproof manner in front of the socket. The protective device according to the invention thus enables the plug, in particular the RJ45 plug, to be connected to the socket safely and in compliance with protection class IP 67. The flange-shaped coupling part is made, for example, of metal or a plastic. This flange-shaped coupling part also has the
Vorteil auf, dass bestehende Buchsen nachträglich auf die Schutzklasse IP 67 nachgerüstet werden können. Das flanschförmige Ankopplungsteil kann mit einem relativ klein dimensionierten Flanschteil ausgestaltet sein, sodass die damit zu versehenden Buchsen gegenseitig sehr nahe beabstandet sein können. Dieses flanschförmige Ankopplungsteil ist somit zum Beispiel auch zur Nachrüstung von Racks geeignet. Das Ankopplungsteil weist eine Führungsöffnung für den Stecker auf, was eine zuverlässige Steckverbindung gewährleistet.The advantage is that existing sockets can be retrofitted to protection class IP 67. The flange-shaped coupling part can be designed with a relatively small dimensioned flange part, so that the bushings to be provided with it can be very closely spaced from one another. This flange-shaped coupling part is therefore also suitable for retrofitting racks, for example. The coupling part has a guide opening for the plug, which ensures a reliable plug connection.

The connector housing is preferably designed as a robust plastic housing. The protective device according to the invention thus enables an RJ45 plug connection which meets protection class IP 67 and is thus protected against water, dirt, oil and mechanical damage.
Das flanschförmig ausgestaltete Ankopplungsteil kann mit kleinem Aufwand in jedes Gerät und in jede Dose integriert werden. Es kann zudem vor jeder RJ45-Buchse angebaut werden.The flange-shaped coupling part can be integrated into any device and into any socket with little effort. It can also be installed in front of every RJ45 socket.
Die erfindungsgemässe Schutzvorrichtung hat, nebst der Dichtfunktion, sowohl eine Führungsfunktion, um den Stecker sicher zu führen, als auch eine mechanische Verbindungsfunktion, um der Steckverbindung eine erhöhte mechanische Widerstandfähigkeit zu verleihen. Eventuell auftretende Vibrationen am Steckergehäuse werden durch die Klemmwirkung der Dichtung auf das Ankopplungsteil umgeleitet, und dadurch nicht oder in nur gedämpfter Form auf die empfindlichen elektrischen Kontakte des Steckers übertragen. Zudem ergibt sich eine Zugentlastung des Steckers, da am Kabel auftretende Zugkräfte über das Steckergehäuse am Ankopplungsteil angreifen.In addition to the sealing function, the protective device according to the invention has both a guiding function to safely guide the plug and a mechanical connection function in order to give the plug connection increased mechanical resistance. Any vibrations that occur on the connector housing are redirected to the coupling part by the clamping action of the seal, and are therefore not transmitted, or only in a damped form, to the sensitive electrical contacts of the connector. In addition, there is a strain relief for the plug, since tensile forces occurring on the cable act on the coupling part via the plug housing.

Die beispielsweise vier Verbindungsmittel 2e mit Einrastteil 2f sind derart angepasst und angeordnet, dass jedes Einrastteil 2f in die Nut le des Ankopplüngsteils 1 eingreifen kann. Eine elastische, ringförmige Dichtung 2a ist zwischen den Verbindungsmitteln 2e liegend angeordnet, und hat die Aufgabe, den Spalt zwischen dem Grundgehäuse 2d und der Dichtkante lf abzudichten. Auf dem Grundgehäuse 2d aufliegend ist ein in Bewegungsrichtung 2p verschiebbar gelagertes Verriegelungsmittel 2b angeordnet, welches je nach Stellung die Bewegungsfreiheit der federnden Verbindungsmittel 2e begrenzt. Das Verriegelungsmittel 2e weist im Innern oben und unten eine vorstehende Einrastnocke 2c auf, welche zum Einrasten in die Einrastvertiefung 2g ausgestaltet ist, sodass dasThe detailed structure of the connector housing 2 is shown in Figure 1. A basic housing 2d has an interior designed in such a way that the plug 3 (in the exemplary embodiment shown an RJ45 plug) is held firmly therein. The basic housing 2d comprises, for example, four resilient, tongue-shaped connecting means 2e, one at the end of each is arranged against the inside protruding locking part 2f. The four connecting means 2e with snap-in part 2f, for example, are adapted and arranged in such a way that each snap-in part 2f can engage in the groove le of the coupling part 1. An elastic, ring-shaped seal 2a is arranged lying between the connecting means 2e and has the task of sealing the gap between the basic housing 2d and the sealing edge lf. Lying on the base housing 2d there is arranged a locking means 2b which is displaceable in the direction of movement 2p and which, depending on the position, limits the freedom of movement of the resilient connecting means 2e. The locking means 2e has a protruding latching cam 2c on the inside and below, which is designed for latching into the latching recess 2g, so that the
Verriegelungsmittel 2b bezüglich dem Grundgehäuse 2d zwei fest vorgegebene Grundstellungen einnehmen kann.Locking means 2b can assume two fixed basic positions with respect to the basic housing 2d.
Das Grundgehäuse 2d umfasst zudem ein Gewinde 2h, welchem Lamellen 2i nachgeordnet sind, welche das Kabel 4 umschliessen. Zudem ist ein das Kabel 4 umschliessenderThe basic housing 2d also comprises a thread 2h, which is followed by lamellae 2i which surround the cable 4. In addition, one enclosing the cable 4
Dichtring 5 vorgesehen. Eine Mutter 2k mit Knickschutz 21 ist auf das Gewinde 2h aufschraubbar, um das Grundgehäuse 2d und das Kabel 4 fest miteinander zu verbinden und gegeneinander abzudichten.Sealing ring 5 is provided. A nut 2k with kink protection 21 can be screwed onto the thread 2h in order to firmly connect the base housing 2d and the cable 4 to one another and to seal them against one another.
Figur 3 zeigt das zusammengesetzte Steckergehäuse 2 kurz bevor dieses zusammen mit dem Stecker 3 in das Ankopplungsteil 1 und die dahinter angeordnete Buchse eingeführt wird. Das Verriegelungsmittel 2b ist zurückgezogen und befindet sich in der ersten Grundstellung, so dass die Verbindungsmittel 2e eine federnde Bewegung ausführen können. In Figur 4 ist das Steckergehäuse 2 mit dem Ankopplungsteil 1 verbunden, indem die beispielsweise vier Einrastteile 2f des Steckergehäuses 2 in die Nut le eingeklinkt sind. Zudem schliesst die Dichtung 2a den Spalt zwischen der Dichtkante lf und dem Grundgehäuse 2d. In dieser Stellung kann das Steckergehäuse 2 wieder vom Ankopplungsteil 1 gelöst werden, indem eine derart grosse Zugkraft auf das Steckergehäuse 2d oder das Kabel 4 ausgeübt wird, dass die Einrastteile 2f aus der Nut le gleiten, indem sich die federnden Verbindungsmittel 2e gegen aussen aufspreizen. Ein ungewolltes Aufspreizen der Verbindungsmittel 2e wird verhindert, indem das Verriegelungsmittel 2b in Richtung 2p zum Ankopplungsteil 1 hin in die zweite Grundstellung verschoben wird, so dass das Verriegelungsmittel 2b die in Figur 5 dargestellteFIG. 3 shows the assembled connector housing 2 shortly before it is inserted together with the connector 3 into the coupling part 1 and the socket arranged behind it. The locking means 2b is retracted and is in the first basic position, so that the connecting means 2e can perform a resilient movement. In Figure 4, the connector housing 2 is connected to the coupling part 1 by the, for example, four snap-in parts 2f of the connector housing 2 are latched into the groove le. In addition, the seal 2a closes the gap between the sealing edge lf and the basic housing 2d. In this position, the connector housing 2 can be detached from the coupling part 1 by exerting such a great tensile force on the connector housing 2d or the cable 4 that the snap-in parts 2f slide out of the groove le by the resilient connecting means 2e spreading outwards. An undesired spreading of the connecting means 2e is prevented by the locking means 2b being displaced in the direction 2p towards the coupling part 1 into the second basic position, so that the locking means 2b is the one shown in FIG
Lage einnimmt. Die Schutzvorrichtung 6 ist in dieser Lage verriegelt. Die federnden Verbindungsmittel 2e können sich nicht gegen aussen aufspreizen, sodass grosse Zugkräfte vom Steckergehäuse 2 über die Einrastteile 2f auf das Ankopplungsteil 1 übertragen werden. Ein Vorteil dieserTakes position. The protective device 6 is locked in this position. The resilient connecting means 2e cannot spread outwards, so that great tensile forces are transmitted from the connector housing 2 to the coupling part 1 via the latching parts 2f. An advantage of this
Anordnung ist darin zu sehen, dass die Schutzvorrichtung 6 diese Zugkräfte im wesentlichen oder vollständig aufnimmt, so dass diese Zugkräfte nicht auf den Stecker 3 beziehungsweise dessen elektrische Verbindung wirken.The arrangement can be seen in the fact that the protective device 6 absorbs these tensile forces substantially or completely, so that these tensile forces do not act on the connector 3 or its electrical connection.
Wird für einen RJ45-Stecker eine Schutzvorrichtung 6 verwendet, wie dies in den Figuren 1 bis 5 dargestellt ist, so ist das Grundgehäuse 2d bevorzugt derart ausgestaltet, dass die Entriegelungslasche 3b des im Grundgehäuse 2d gehaltenen Steckers 3 ständig auf der Oberfläche des Steckers 3 aufliegt. Dadurch kann dieIf a protective device 6 is used for an RJ45 plug, as is shown in FIGS. 1 to 5, the basic housing 2d is preferably designed in such a way that the unlocking tab 3b of the plug 3 held in the basic housing 2d constantly rests on the surface of the plug 3 , This allows the
Entriegelungslasche 3b nicht in Wirkverbindung mit der in der Buchse zum Verriegeln vorgesehenen Anordnung treten. Die Verriegelung zwischen Stecker 3 und Buchse wird somit nicht durch die Entriegelungslasche 3b bewirkt, sondern durch die Verriegelung des Steckergehäuses 2 mit dem Ankopplungsteil 1.Release tab 3b does not come into active connection with the arrangement provided in the socket for locking. The locking between plug 3 and socket is thus not effected by the release tab 3b, but by locking the connector housing 2 with the coupling part 1.
Wie in Figur 5 dargestellt, kann die Verriegelung derart gelöst werden, dass das Verriegelungsmittel 2b in Richtung 2P' verschoben wird.As shown in FIG. 5, the locking can be released in such a way that the locking means 2b is displaced in the direction 2P '.
Ein zweites Ausführungsbeispiel der erfindungsgemässen Schutzvorrichtung 6 ist in den Figuren 6, 7 und 8 dargestellt. Das Steckergehäuse 2 ist als elastischer Hohlkörper ausgestaltet, welcher über einen flexiblen Faltenbalg in eine Dichtung 2a mündet, um den Innenraum des Steckergehäuses 2 gegen das Kabel 4 abzudichten. Das Steckergehäuse 2 besteht vorzugsweise aus einem elastischen, weichen Kunststoff. Wie aus dem in Figur 8 dargestellten Längsschnitt durch die Schutzvorrichtung 6 ersichtlich, weist das Steckergehäuse 2 an der demA second exemplary embodiment of the protective device 6 according to the invention is shown in FIGS. 6, 7 and 8. The connector housing 2 is designed as an elastic hollow body, which opens into a seal 2a via a flexible bellows in order to seal the interior of the connector housing 2 against the cable 4. The connector housing 2 is preferably made of an elastic, soft plastic. As can be seen from the longitudinal section through the protective device 6 shown in FIG. 8, the plug housing 2 has the
Ankopplungsteil 1 zugewandten Stirnseite ein gegen innen vorstehendes Einrastteil 2f auf, welches vorzugsweise um 360 Grad umlaufend ausgestaltet ist, so dass das Einrastteil 2f über dem gesamten Umfang des Kragens la in der Nut le liegt. Somit ergibt sich zwischen demCoupling part 1 facing end face an inward protruding snap-in part 2f, which is preferably designed to rotate 360 degrees, so that the snap-in part 2f lies over the entire circumference of the collar la in the groove le. Thus there is between the
Ankopplungsteil 1 und dem Steckergehäuse 2 eine dichte Verbindung. Auf Grund der elastischen Eigenschaften des als Gummitülle ausgestalteten Steckergehäuses 2 kann das Einrastteil 2f sehr einfach in den Eingriff mit der Nut le gebracht werden, beziehungsweise wieder aus der Nut le entfernt werden. Das in Figur 6 und 7 dargestellte Ankopplungsteil 1 weist beispielsweise Haken li auf, welche in entsprechend angepasst ausgestaltete Durchbrechungen einer Buchsenabdeckung eingreifen können, so dass das Ankopplungsteil 1 sehr einfach auf eine bestehende Buchse aufgesetzt werden kann. Die Verriegelung des RJ45-Steckers 3 erfolgt in der Buchse in an sich bekannter Weise über die Arretiernase 3a, welche ein integrierter Bestandteil der Entriegelungs- lasche 3b ist, da das elastische Steckergehäuse 2 kaum Zugkräfte aufnehmen kann. Die dargestellteCoupling part 1 and the connector housing 2 a tight connection. On account of the elastic properties of the plug housing 2 designed as a rubber grommet, the snap-in part 2f can be brought into engagement with the groove le very easily, or removed again from the groove le. The coupling part 1 shown in FIGS. 6 and 7 has, for example, hooks li, which can engage in appropriately designed openings in a socket cover, so that the coupling part 1 can be placed very easily on an existing socket. The RJ45 plug 3 is locked in the socket in a manner known per se via the locking lug 3a, which is an integrated part of the unlocking tab 3b, since the elastic plug housing 2 can hardly absorb tensile forces. The illustrated
Schutzvorrichtung wird derart verwendet, dass, in einem ersten Schritt, wie in Figur 7 dargestellt, der Stecker 3 in das Ankopplungsteil 1 eingeführt wird und der Stecker 3 über die Arretiernase 3a in der Buchse arretiert wird. Daraufhin wird, wie in Fig. 6 dargestellt, das elastische Steckergehäuse 2 zum Ankopplungsteil 1 hin verschoben und das Einrastteil 2f in den Eingriff mit der Nut le gebracht, wie dies in Figur 8 dargestellt ist. Somit ist der Stecker 3 durch die Schutzvorrichtung 6, umfassend das Steckergehäuse 2 sowie das Ankopplungsteil 1, vor einer Verschmutzung und vor Flüssigkeiten geschützt.Protective device is used in such a way that, in a first step, as shown in FIG. 7, the plug 3 is inserted into the coupling part 1 and the plug 3 is locked in the socket via the locking lug 3a. Thereupon, as shown in FIG. 6, the elastic connector housing 2 is shifted towards the coupling part 1 and the latching part 2f is brought into engagement with the groove 1, as shown in FIG. Thus, the connector 3 is protected from contamination and liquids by the protective device 6, including the connector housing 2 and the coupling part 1.
Figur 8 zeigt schematisch die Stellung derFigure 8 shows schematically the position of the
Entriegelungslasche 3b bei dem in die Buchse eingestecktem Stecker 3. Es kann sich als vorteilhaft erweisen, das Steckergehäuse 2 mit einer vorstehenden Nocke 2n zu versehen, welche derart angeordnet ist, dass sie unterhalb der Entriegelungslasche 3b zu liegen kommt. Um den Stecker 3 aus der Buchse zu lösen, wird das Steckergehäuse 2 an der mit der Nocke 2n versehenen Stelle nach oben gedrückt, so dass die Entriegelungslasche 3b angehoben wird und die Steckverbindung gelöst wird. Daraufhin kann der Stecker 3 zusammen mit dem Steckergehäuse 2 abgezogen werden. Auch bei diesem Ausführungsbeispiel ist der Kragen Ankopplüngsteils 1 derart dimensioniert, dass die Entriegelungslasche 3b von aussen zugänglich ist und manuell betätigt werden kann.Unlocking tab 3b with the plug 3 inserted into the socket. It may prove advantageous to provide the connector housing 2 with a protruding cam 2n, which is arranged such that it comes to rest below the unlocking tab 3b. In order to detach the plug 3 from the socket, the plug housing 2 is pressed up at the point provided with the cam 2n, so that the unlocking tab 3b is raised and the plug connection is released. The plug 3 can then be removed together with the plug housing 2. In this exemplary embodiment, too, the collar of the coupling part 1 is dimensioned such that the unlocking tab 3b is accessible from the outside and can be operated manually.
Es versteht sich, dass die Schutzvorrichtung mit bekannten Steckern kombiniert werden kann, insbesondere mit einem Lichtwellenleiter-Stecker, Universal-Serial-Bus-Stecker (USB) oder RJ45-Stecker. It goes without saying that the protective device can be combined with known plugs, in particular with one Fiber optic connector, universal serial bus connector (USB) or RJ45 connector.
