Description

Die Erfindung geht aus von einer Schutzkappe für Steckverbindergehäuse nach dem Oberbegriff des unabhängigen Anspruchs 1.The invention relates to a protective cap for connector housing according to the preamble of independent claim 1.

Derartige Schutzkappen werden benötigt um Steckverbindergehäuse, die nicht mit einem Gegensteckverbinder gesteckt sind, vor dem Einfluss von Schmutz, Staub, Feuchtigkeit und anderen Umwelteinflüssen zu schützen. Gerade in rauer Industrieumgebung oder bei Anwendungen im Freien besteht das Risiko, dass die Kontakte ungenutzter Steckverbinder verschmutzen und eine Kontaktierung mit einem Gegensteckverbinder nicht mehr möglich ist. Insbesondere bei Steckverbindergehäusen für Lichtwellenleiter oder anderen, schmutzanfälligen Kontakten ist ein derartiger Schutz nötig.Such protective caps are required to protect connector housings which are not plugged with a mating connector from the influence of dirt, dust, moisture and other environmental influences. Especially in harsh industrial environments or in outdoor applications, there is the risk that the contacts of unused connectors contaminate and a contact with a mating connector is no longer possible. In particular, in connector housings for optical fibers or other, dirt-prone contacts such protection is necessary.

Beim Transport und der Montage von Steckverbindergehäusen auf Baustellen oder außerhalb von geschützten Räumen können die Kontakte leicht verschmutzen. Derartige Verschmutzungen sind bei Lichtwellenleiterkontakten besonders ungünstig, da durch eine verschmutzte Stirnfläche des Lichtwellenleiters die Übertragung von Signalen verschlechtert, gestört und im schlimmsten Fall verhindert wird.When transporting and mounting connector housings on construction sites or outside protected areas, the contacts can easily become dirty. Such contamination is particularly unfavorable in fiber optic contacts, as deteriorated by a dirty face of the optical waveguide, the transmission of signals, disturbed and prevented in the worst case.

Dabei wird der Blindstecker anstelle eines männlichen Steckers in die Stecköffnung eingesetzt und dichtet diese dabei ab.The US 2001/0024907 A1 discloses a dummy plug for sealing a plug-in opening of a female plug. The dummy plug is inserted instead of a male plug into the plug-in opening and seals it off.

Die DE 20 2011 050 067 U1 zeigt eine Schutzkappe für Steckverbinder, wobei an dem Steckverbinder ein Gewinde zur mechanischen Verbindung des Steckverbinders mit einem Gegenstecker vorgesehen ist. Die Schutzkappe weist ebenfalls ein Gewinde auf, mittels welchem die Schutzkappe anstelle des Gegensteckers mit dem Steckverbinder verschraubt werden kann. Durch die Schutzkappe wird das Eindringen von Umwelteinflüssen in den Kontaktbereich des Steckverbinders verhindert.The DE 20 2011 050 067 U1 shows a protective cap for connectors, wherein the connector threaded to the mechanical Connection of the connector is provided with a mating connector. The protective cap also has a thread by means of which the protective cap can be screwed to the connector instead of the mating connector. The protective cap prevents the penetration of environmental influences into the contact region of the connector.

Aus der Druckschrift DE 10 2012 100 615 A1 ist ein Steckverbindungssystem bekannt, welches mehrere gestaffelte Rasteinheiten umfasst, die durch einen Schiebemechanismus entrastet werden können. Durch die gestaffelten Rasteinheiten, auch Raststufen oder Rastpunkte genannt, ist ein Niveauausgleich zwischen den Kontaktmitteln eines Steckverbinder und eines Gegensteckverbinder möglich.From the publication DE 10 2012 100 615 A1 a connector system is known, which comprises a plurality of staggered locking units, which can be unlocked by a sliding mechanism. Due to the staggered locking units, also called latching steps or locking points, a level compensation between the contact means of a connector and a mating connector is possible.

Die US 2008/310795 offenbart eine Adapterstaubkappe, welche einen Steckverbinder für Lichtwellenleiter, welche in der inneren Geometrie eines LWL-Steckverbinders verrastet und über eine visuelle Anzeige verfügt.The US 2008/310795 discloses an adapter dust cap which incorporates a fiber optic connector that latches within the internal geometry of a fiber optic connector and has a visual indication.

In der US 5 704 796 A stellt einen Blindstecker für Netzkabelsteckdosen vor, welcher einen Nachweis liefert, dass die Netzwerksteckdose verwendet wurde.In the US 5,704,796 A provides a dummy plug for power cord outlets, which provides evidence that the network outlet has been used.

Die WO 2011/052356 A1 offenbart eine Schutzvorrichtung für optische Steckverbinder. Dabei wird die Schutzvorrichtung auf den Steckverbinder aufgesteckt und dichtet ihn gegen äußere Einflüsse ab.The WO 2011/052356 A1 discloses a protection device for optical connectors. The protective device is plugged onto the connector and seals it against external influences.

Aus der US 5 202 949 A ist ein Staubschutz für faseroptische Ferrulen bekannt. Dieser weist auch eine Verbindungsmöglichkeit zur schützenden optischen Faser auf, sodass eine Verliersicherung des Staubschutzes gewährleistet ist.From the US 5,202,949 A Dust protection for fiber optic ferrules is known. This also has a connection to the protective optical fiber, so that a captive of dust protection is guaranteed.

Die aus der DE 10 2012 100 615 A1 bekannten Steckverbindungssysteme sind zur Nutzung für sogenannten SFP-Transceiver (small form-factor pluggable) vorgesehen. Die SFP-Transceiver werden im Steckverbindergehäuse - meist ein sogenanntes Anbaugehäuse für Wanddurchführungen - eingesetzt und mit einem Gegensteckergehäuse, welches einen oder zwei Gegenstecker beherbergt, kontaktiert. Dabei werden bei dieser Bauart die SFP-Transceiver nicht fest im Steckverbindergehäuse verrastet, sondern über die Verrastung zwischen Steckverbindergehäuse und Gegensteckgehäuser gehalten. Es ist lediglich eine Verrastung des SFP-Transceivers mit den Steckverbindern des Gegensteckers vorgesehen.The from the DE 10 2012 100 615 A1 known connector systems are provided for use in so-called SFP transceivers (small form-factor pluggable). The SFP transceivers are in the connector housing - usually a so-called mounting housing for wall penetrations - used and contacted with a mating connector housing one or two mating connector. In this design, the SFP transceivers are not firmly locked in the connector housing, but held on the latching between the connector housing and mating connector housings. It is only provided a latching of the SFP transceiver with the connectors of the mating connector.

Daraus ergibt sich, dass beim Dekontaktieren derartiger Steckverbindungssystem der SFP-Transceiver zusammen mit dem Gegenstecker aus dem Steckverbindergehäuse gezogen wird. Nachteilig wirkt sich hierbei aus, dass der SFP-Transceiver nicht selbstständig im Steckverbinder gehalten und gesichert ist. Beim Transport des Steckverbinders sitzt der SFP-Transceiver lose im Steckverbinder und wird nur durch eine Schutzkappe, die den Steckverbinder vor Umwelteinflüssen schützen soll, vor dem Herausfallen gesichert.It follows that when decontacting such connector system, the SFP transceiver is pulled out of the connector housing together with the mating connector. The disadvantage here is that the SFP transceiver is not independently held in the connector and secured. When transporting the connector, the SFP transceiver sits loosely in the connector and is prevented from falling out only by a protective cap which is intended to protect the connector from environmental influences.

Beim Entfernen der Schutzkappe kann es zudem dazu kommen, dass der SFP-Transceiver aus dem Steckverbinder ungewollt herausfällt und verschmutzt oder beschädigt wird. Ebenso kann der SFP-Transceiver im Steckverbinder verhaken oder klemmen und so ein Herausholen auf Grund der beengten Verhältnisse nicht möglich. Auch Transportschäden durch Wackeln im Steckverbinder sind denkbar.When the protective cap is removed, it may also cause the SFP transceiver to fall out of the connector unintentionally, becoming dirty or damaged. Likewise, the SFP transceiver can hook or pinch in the connector and so a retrieval due to the cramped conditions not possible. Transport damage due to wobbling in the connector is also conceivable.

Aufgabenstellungtask

Die Aufgabe der Erfindung besteht darin, für ein vorgestelltes Steckverbindersystem eine Transportsicherung für SFP-Transceiver vorzustellen. Der SFP-Transceiver soll vor ungewolltem Herausfallen und Verlieren aus einem Steckverbinder, sowie vor Transportschäden durch Verrutschen und Wackeln geschützt werden. Gleichermaßen soll mit der Transportsicherung eine einfaches Entfernen des SFP-Transceivers aus den Steckverbinder ermöglicht werden, ohne diesen zu beschädigen oder einen Steckverbinder dafür nutzen zu müssen.The object of the invention is to introduce a transport protection for SFP transceiver for a presented connector system. The SFP transceiver should be protected against unintentional falling out and loss from a connector, as well as against transport damage caused by slipping and shaking. Similarly, the transport lock should allow easy removal of the SFP transceiver from the connector without damaging it or using a connector.

Die Aufgabe wird durch die kennzeichnenden Merkmale des unabhängigen Anspruchs 1 gelöst.The object is solved by the characterizing features of independent claim 1.

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

Bei der Erfindung handelt es sich um eine Schutzkappe für Steckverbindergehäuse die zur Aufnahme von Steckverbindermodulen vorgesehen sind. Für derartige Steckverbindergehäuse werden bevorzugt sogenannte Anbaugehäuse verwendet. Diese Anbaugehäuse werden zur Gehäusedurchführungen benutzt, um im Gehäuse liegende Kontakte oder Steckverbindermodule, vorzugsweise sogenannte SFP-Transceiver, mit einem Gegenstecker zu kontaktieren. Der Gegenstecker wird dabei mit dem Steckverbindergehäuse mechanisch kontaktiert.In the invention is a protective cap for connector housings which are provided for receiving connector modules. For such connector housing so-called mounting housing are preferably used. These mounting housings are used for housing bushings to contact located in the housing contacts or connector modules, preferably so-called SFP transceiver with a mating connector. The mating connector is contacted mechanically with the connector housing.

Die Schutzkappe bildet eine Steckseite sowie eine Griffseite aus. Die Griffseite ist zur Anfassen der Schutzkappe durch den Benutzer vorgesehen. Eine ergonomische Ausbildung der Griffseite trägt zur besseren Handhabung bei.The protective cap forms a plug-in side and a handle side. The handle side is provided for gripping the protective cap by the user. An ergonomic design of the handle side contributes to better handling.

Die der Griffseite gegenüberliegende Steckseite ist zum umweltdichten Verschließen eines Steckverbindergehäuses vorgesehen. Dabei ist die Steckseite der Schutzkappe entsprechend eines Gegensteckers zum Steckverbindergehäuse ausgebildet. Das heißt, dass die Schutzkappe anstelle eines Gegensteckers mit dem Steckverbindergehäuse verbunden werden kann. Durch eine entsprechende Dichtung wird das Steckverbindergehäuse umweltdicht verschlossen.The side opposite the handle side is provided for the environmentally sealed closing of a connector housing. In this case, the plug side of the protective cap is designed in accordance with a mating connector to the connector housing. This means that the protective cap can be connected to the connector housing instead of a mating connector. By an appropriate seal the connector housing is sealed environmentally sealed.

Erfindungsgemäß weist die Steckseite der Schutzkappe zumindest eine Aufnahme auf, welche zur mechanischen Kontaktierung eines Steckverbindermoduls ausgebildet und vorgesehen ist. Dabei entspricht die zumindest eine Aufnahme in ihrer Form einem Gegensteckverbinder, der mit dem Steckverbindermodul kontaktiert werden kann.According to the invention, the plug side of the protective cap has at least one receptacle which is designed and provided for the mechanical contacting of a plug connector module. In this case, the at least one receptacle corresponds in shape to a mating connector which can be contacted with the connector module.

Die Aufnahme in der Steckseite der Schutzkappe kontaktiert alternativ zum Gegensteckverbinder mechanisch mit dem Steckverbindermodul. In einer bevorzugten Ausführungsform ist die zumindest eine Aufnahme stiftförmig ausgebildet, so dass diese in die Kontaktbuchsen eines Steckverbindermoduls einführbar sind.The receptacle in the plug side of the protective cap contacts the mating plug connector mechanically with the plug connector module as an alternative. In a preferred embodiment, the at least one receptacle is pin-shaped, so that they can be inserted into the contact sockets of a connector module.

Entsprechend eines Gegensteckverbinders kann die Aufnahme mit einer passenden Verrastung im Steckverbindermodul verrasten. In einer alternativen Ausführungsform ist die zumindest eine Aufnahme aus einem elastischen Polymer hergestellt und in ihrer Abmessung etwas größer als die entsprechende Aufnahme im Steckverbindermodul. Dadurch wird die Aufnahme beim Einführen in das Steckverbindermodul in diesem verklemmt und stellt so eine mechanische Verbindung zwischen Schutzkappe und Steckverbindermodul her.According to a mating connector, the receptacle can latch with a matching latching in the connector module. In an alternative embodiment, the at least one receptacle is made of an elastic polymer and slightly larger in size than the corresponding receptacle in the connector module. As a result, the recording when inserted into the connector module is jammed in this and thus establishes a mechanical connection between the protective cap and connector module.

In einer bevorzugten Ausführungsform sind an der Steckseite der Schutzkappe zwei Aufnahmen vorgesehen. Diese sind zur mechanischen Kontaktierung eines Steckverbindermoduls mit zwei Ein-/Ausgängen (Ports) ausgebildet. Diese Art von Steckverbindermodulen wird vor allem in bei SFP-Transceivern verwendet, die zur Kommunitkation einen optischen Eingang und einen optischen Ausgang aufweisen.In a preferred embodiment, two receptacles are provided on the mating side of the protective cap. These are designed for mechanical contacting of a connector module with two inputs / outputs (ports). This type of connector module is mainly used in SFP transceivers that have an optical input and an optical output for communication.

Eine spezielle Ausführungsform sieht vor, die Steckseite der Schutzkappe variabel für ein oder zwei Aufnahmen anzubieten. Dafür ist in der Schutzkappe ein Mittel zur Befestigung von alternativ einer oder zwei Aufnahmen vorgesehen. Das Mittel wird dabei in der Schutzkappe verrastet und weist beispielsweise drei Öffnungen auf. In die drei nenbeneinander liegenden Öffnungen kann mittig eine Aufnahme eingesetzt werden, oder alternativ in die beiden äußeren jeweils eine Aufnahme.A special embodiment provides to offer the mating side of the cap variable for one or two shots. For a means for attachment of alternatively one or two shots is provided in the protective cap. The agent is latched in the cap and has, for example, three openings. In the three nenbeneinander horizontal openings, a receptacle can be used in the middle, or alternatively in each of the two outer a receptacle.

Dadurch kann die Schutzkappe von der Kontaktierung eines Steckverbindermoduls mit zwei Ports auf die Kontaktierung eines Steckverbindermoduls mit nur einem Port umgerüstet werden. Dies kann für Steckverbindermodule mit nur einem, mittig gelegenen, bidirektionalen Port zweckmäßig sein. Alternativ kann das Mittel zur Befestigung der Aufnahmen auch so ausgebildet werden, dass entsprechend andere Anzahlen von Anfnahmen eingesetzt werden können.As a result, the protective cap can be converted from the contacting of a connector module with two ports to the contacting of a connector module with only one port. This may be desirable for connector modules with only one, centered, bidirectional port. Alternatively, the means for mounting the receptacles can also be designed so that correspondingly different numbers of receptions can be used.

Durch die zumindest eine Aufnahme an der Steckseite der Schutzkappe kann ein Steckverbindermodul mechanisch mit der Schutzkappe verbunden werden. Beim Abziehen der Schutzkappe vom Steckverbindergehäuse ist so ein Herausfallen und Verlieren des Steckverbindermouls nicht mehr möglich. Das Steckverbindermodulwird zusammen mit der Schutzkappe vom Steckverbindergehäuse abgezogen und kann von der Schutzkappe auf einen Gegenstecker aufgesetzt werden. Während dessen ist ein Schutz des Steckverbindergehäuses und Steckverbindermoduls gegen Umwelteinflüsse weiterhin gegeben.By the at least one receptacle on the plug side of the protective cap, a connector module can be mechanically connected to the protective cap. When removing the cap from the connector housing so falling out and losing the connector module is no longer possible. The connector module is removed from the connector housing along with the protective cap and can be placed by the protective cap on a mating connector. Meanwhile, a protection of the connector housing and connector module against environmental influences continues to exist.
