Description

Die vorliegende Erfindung betrifft einen RJ45-Stecker mit einem Steckergehäuse, das eine Einführöffnung zum Einführen eines Kabels aufweist, und einer Zugentlastungseinrichtung, die ausgeführt ist, das Kabel außenseitig an dem Steckergehäuse zu klemmen.The present invention relates to an RJ45 plug with a connector housing having an insertion opening for insertion of a cable, and a strain relief, which is designed to clamp the cable outside of the connector housing.

Derartige RJ45-Stecker werden für eine Datenverkabelung verwendet, insbesondere nach dem Twisted Pair-Standard. Ein Datenkabel nach diesem Stand umfasst acht einzelne Adern, die über den RJ45-Stecker mit einer entsprechenden Buchse verbindbar sind. Dazu müssen die einzelnen Adern des Kabels in dem RJ45-Stecker kontaktiert werden.Such RJ45 connectors are used for data cabling, especially according to the twisted pair standard. A data cable according to this state comprises eight individual wires, which can be connected via the RJ45 plug with a corresponding socket. To do this, the individual wires of the cable must be contacted in the RJ45 plug.

Zum Schutz des RJ45-Steckers ist üblicherweise eine Zugentlastungseinrichtung vorgesehen, mit der das Kabel insgesamt klemmend an dem RJ45-Stecker gehalten wird. Somit können die Adern bei einer Zugbelastung nicht aus ihren Kontakten gerissen werden, wodurch der RJ45-Stecker vor Beschädigungen durch mechanische Belastungen geschützt wird.To protect the RJ45 connector, a strain relief device is usually provided, with which the cable is held in its entirety by clamping on the RJ45 connector. Thus, the wires can not be torn from their contacts under a tensile load, whereby the RJ45 connector is protected from damage by mechanical stress.

In der Praxis hat sich jedoch als problematisch erwiesen, den RJ45-Stecker zuverlässig vor Beschädigungen zu schützen, da Kabel mit unterschiedlichen Außendurchmessern verwendet werden, was eine zuverlässige Zugentlastung erschwert. Diesem Problem wir durch die Verwendung von unterschiedlichen RJ45-Steckern mit angepassten Zugentlastungseinrichtungen begegnet. Bekannte Zugentlastungseinrichtungen können Kabel mit unterschiedlichen Außendurchmessern nicht gleichermaßen zuverlässig klemmen und/oder erschweren die Montage des RJ45-Steckers.In practice, however, has proven to be problematic to protect the RJ45 connector reliable from damage, since cables are used with different outer diameters, which makes reliable strain relief difficult. We counter this problem by using different RJ45 plugs with adapted strain relief devices. Known strain relief devices can not clamp cables with different outer diameters equally reliable and / or make it difficult to install the RJ45 connector.

Bei diesen RJ45-Steckern ist es auch schwierig, die Adern mit den entsprechenden Kontakten zu verbinden. Daher ist es wünschenswert, dass der RJ45-Stecker eine einfache Verbindung mit dem Kabel erlaubt.With these RJ45 plugs it is also difficult to connect the wires to the corresponding contacts. Therefore, it is desirable for the RJ45 plug to allow easy connection to the cable.

In diesem Zusammenhang ist aus der DE 10 2008 064 535 A1 ein elektrischer Verbindungsstecker bekannt. Der Verbindungsstecker umfasst ein Verbindungsmodul, das mehrere Kontaktelemente aufweist zur Herstellung einer elektrischen Verbindung mit korrespondierenden Kontaktelementen einer Verbindungsbuchse, und ein Anschlussmodul, das mehrere Anschlusselemente aufweist zum Anschließen jeweils einer Ader eines Kabels. das Anschlussmodul ist mit dem Verbindungsmodul lösbar verbindbar zur Herstellung einer elektrischen Verbindung zwischen den Anschlusselementen und jeweils einem Kontaktelement. Das Verbindungsmodul umfasst ein Gehäuse, in das das Anschlussmodul einführbar ist, sowie eine mit dem Gehäuse verbundene Zugentlastung, die das Anschlussmodul übergreift, wobei mittels der Zugentlastung ein an das Anschlussmodul angeschlossenes Kabel am Verbindungsmodul festlegbar ist.In this context is from the DE 10 2008 064 535 A1 an electrical connector known. The connector comprises a connection module having a plurality of contact elements for establishing an electrical connection with corresponding contact elements of a connection socket, and a connection module having a plurality of connection elements for connecting in each case a wire of a cable. the connection module can be detachably connected to the connection module for producing an electrical connection between the connection elements and in each case one contact element. The connection module comprises a housing into which the connection module can be inserted, and a strain relief connected to the housing, which engages over the connection module, wherein a cable connected to the connection module can be fixed to the connection module by means of the strain relief.

Ausgehend von dem oben genannten Stand der Technik liegt der Erfindung somit die Aufgabe zugrunde, einen RJ45-Stecker der oben genannten Art anzugeben, der ein einfaches und zuverlässiges Klemmen von Kabeln mit unterschiedlichem Durchmesser ermöglicht und einfach zu montieren ist.Based on the above-mentioned prior art, the invention is therefore based on the object of specifying an RJ45 plug of the type mentioned above, which allows a simple and reliable clamping of cables with different diameters and is easy to assemble.

Die Lösung der Aufgabe erfolgt erfindungsgemäß durch die Merkmale des unabhängigen Anspruchs. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the invention by the features of the independent claim. Advantageous embodiments of the invention are specified in the subclaims.

Erfindungsgemäß wird die Aufgabe somit gelöst durch einen RJ45-Stecker mit einem Steckergehäuse, das eine Einführöffnung zum Einführen eines Kabels aufweist, und einer Zugentlastungseinrichtung, die ausgeführt ist, das Kabel außenseitig an dem Steckergehäuse zu klemmen, wobei die Zugentlastungseinrichtung ein erstes und ein zweites Klemmelement umfasst, die an in Umfangsrichtung gegenüberliegenden Seiten der Einführöffnung an dem Steckergehäuse angeordnet sind, das erste Klemmelement in Richtung zu dem zweiten Klemmelement verschwenkbar an dem Steckergehäuse gehalten ist, die Zugentlastungseinrichtung Fixiermittel aufweist, mit denen das erste Klemmelement relativ zu dem zweiten Klemmelement in einer Mehrzahl Verschwenkpositionen fixierbar ist, und das erste Klemmelement an seiner dem zweiten Klemmelement zugewandten Seite eine Bogenform aufweist, wobei der Bogen konkav in Längsrichtung des Kabels ausgebildet ist.According to the invention the object is thus achieved by an RJ45 plug with a connector housing, which has an insertion opening for inserting a cable, and a strain relief, which is designed to clamp the cable outside of the connector housing, wherein the strain relief means a first and a second clamping element comprises, which are arranged on circumferentially opposite sides of the insertion opening on the plug housing, the first clamping element is held in the direction of the second clamping element pivotally mounted on the plug housing, the strain relief device has fixing means with which the first clamping element relative to the second clamping element in a plurality Verschwenkpositionen is fixable, and the first clamping element on its side facing the second clamping element has an arc shape, wherein the arc is concave in the longitudinal direction of the cable.

Grundidee der vorliegenden Erfindung ist es also, die Zugentlastungseinrichtung durch das Verschwenken des ersten Klemmelements zur Klemmung von Kabeln mit unterschiedlichen Durchmessern anzupassen. Dies erfolgt durch die Mehrzahl Verschwenkpositionen, in denen Kabel mit unterschiedlichen Durchmessern geklemmt werden können. Die Bogenform des ersten Klemmelements bewirkt dabei eine zuverlässige Klemmung, da zwischen dem ersten Klemmelement und dem Kabel jeweils ein gleichartiger Kontaktbereich gebildet wird. Das erste Klemmelement ist vorzugsweise so ausgeführt, dass eine Kraftübertragung von dem ersten Klemmelement senkrecht auf das Kabel erfolgt. Das Kabel liegt somit jeweils tangential an der Bogenform des ersten Klemmelements an.The basic idea of the present invention is therefore to adapt the strain relief device by pivoting the first clamping element for clamping cables with different diameters. This is done by the plurality of pivoting positions in which cables with different diameters can be clamped. The arc shape of the first clamping element causes a reliable clamping, since between the first clamping element and the cable each have a similar contact area is formed. The first clamping element is preferably designed so that a power transmission from the first clamping element is perpendicular to the cable. The cable thus lies tangentially against the arch form of the first clamping element.

Das zweite Klemmelement kann fest an dem Steckergehäuse gehalten sein, oder in Übereinstimmung mit dem ersten Klemmelement ebenfalls verschwenkbar sein. Die Klemmung erfolgt in letzterem Fall durch das Verschwenken der Klemmelemente relativ zu einander. Auch kann das zweite Klemmelement in diesem Fall wie das erste Klemmelement eine Bogenform aufweisen.The second clamping element may be fixedly held on the plug housing, or also be pivotable in accordance with the first clamping element. The clamping takes place in the latter case by the pivoting of the clamping elements relative to each other. Also, in this case, like the first clamping element, the second clamping element can have an arched shape.

Die Zugentlastungseinrichtung kann als Einheit insgesamt an dem Steckergehäuse angebracht sein. Alternativ ist es möglich, dass die Zugentlastungseinrichtung aus Bauteilen und/oder Baugruppen gebildet ist, die individuell an dem Steckergehäuse angebracht sind.The strain relief device may be mounted as a whole on the connector housing. Alternatively, it is possible that the strain relief device is formed from components and / or assemblies that are individually attached to the connector housing.

In vorteilhafter Ausgestaltung der Erfindung ist der RJ45-Stecker derart weitergebildet, dass das Steckergehäuse eine erste und eine zweite Gehäuseschale aufweist, und das erste Klemmelement an der ersten Gehäuseschale und das zweite Klemmelement an der zweiten Gehäuseschale gehalten ist. Somit kann das Kabel einfach in das Steckergehäuse eingeführt werden, da ein Einfädeln durch die Zugentlastungseinrichtung hindurch entfällt. Die Zugentlastungseinrichtung kann sich somit in einem geöffneten Zustand befinden, um das Kabel in das Steckergehäuse einzuführen, und erst im Anschluss daran um das Kabel herum geschlossen werden, so dass das Kabel in einem geschlossenen Zustand des Steckergehäuses geklemmt wird. Die Zugentlastungseinrichtung kann erst nach dem Verbinden der Gehäuseschalen zum Klemmen des Kabels geschlossen werden. Die Einführöffnung ist besonders bevorzugt in einem Verbindungsbereich der beiden Gehäuseschalen angeordnet. Dabei kann die Einführöffnung als Aussparung in einer beliebigen Gehäuseschale ausgeführt sein, die beim Verbinden der Gehäuseschalen geschlossen wird. Auch kann die Einführöffnung von zwei korrespondierenden Aussparungen an den beiden Gehäuseschalen beim Verbinden der Gehäuseschalen gebildet werden. Somit muss das Kabel auch nicht durch die Einführöffnung in das Steckergehäuse eingefädelt werden, da die Einführöffnung erst nach dem Einbringen des Kabels geschlossen wird. Auch die Verbindung von Adern des Kabels mit einer Platine des RJ45-Steckers, die vorzugsweise fest an dem Steckergehäuse angebracht ist, besonders bevorzugt an der zweiten Gehäuseschale, kann somit einfach durchgeführt werden. In einer alternativen Ausführungsform kann die Platine ein separates Bauteil sein, das nicht fest mit dem Steckergehäuse verbunden ist. Entsprechend können die Adern des Kabels außerhalb des Steckergehäuses mit der Platine verbunden werden, die Platine kann danach in das Steckergehäuse eingebracht werden, und im Anschluss daran können die Gehäuseschalen miteinander verbunden werden.In an advantageous embodiment of the invention, the RJ45 connector is further developed such that the connector housing has a first and a second housing shell, and the first clamping element is held on the first housing shell and the second clamping element on the second housing shell. Thus, the cable can easily into the connector housing be inserted, since threading through the strain relief device passes through. The strain relief device may thus be in an open condition for inserting the cable into the connector housing and thereafter closing it around the cable so that the cable is clamped in a closed state of the connector housing. The strain relief can only be closed after connecting the housing shells for clamping the cable. The insertion opening is particularly preferably arranged in a connection region of the two housing shells. In this case, the insertion opening can be designed as a recess in any housing shell, which is closed when connecting the housing shells. Also, the insertion of two corresponding recesses may be formed on the two housing shells when connecting the housing shells. Thus, the cable must not be threaded through the insertion opening in the connector housing, since the insertion is closed only after the introduction of the cable. Also, the connection of wires of the cable with a board of the RJ45 connector, which is preferably fixedly mounted on the connector housing, particularly preferably on the second housing shell, can thus be easily performed. In an alternative embodiment, the board may be a separate component that is not fixedly connected to the connector housing. Accordingly, the wires of the cable outside the connector housing can be connected to the board, the board can then be inserted into the connector housing, and subsequently the housing shells can be interconnected.

In vorteilhafter Ausgestaltung der Erfindung ist der RJ45-Stecker derart weitergebildet, dass die erste und die zweite Gehäuseschale in einem der Einführöffnung entgegengesetzten Bereich verschwenkbar aneinander gehalten sind. Somit kann der RJ45-Stecker vollständig montiert zur Benutzung bzw. der Verbindung mit dem Kabel bereitgestellt werden. Das Öffnen bzw. Schließen des Steckergehäuses kann entsprechend durch das Verschwenken der Gehäuseschalen realisiert werden. Die Herstellung und Auslieferung des RJ45-Steckers erfolgt vorzugsweise derart, dass das Steckergehäuse geöffnet ist. Weiter bevorzugt sind die beiden Gehäuseschalen in der geöffneten Stellung arretiert. Somit kann die Montage des RJ45-Steckers mit geringem Zeitaufwand durchgeführt werden.In an advantageous embodiment of the invention, the RJ45 connector is further developed such that the first and the second housing shell in a region opposite to the insertion opening are pivotally held together. Thus, the RJ45 connector can be provided fully assembled for use or connection to the cable. The opening or closing of the connector housing can be realized in accordance with the pivoting of the housing shells. The production and delivery of the RJ45 connector is preferably carried out such that the connector housing is open. More preferably, the two housing shells are locked in the open position. Thus, the installation of the RJ45 connector can be carried out in a small amount of time.

Besonders bevorzugt sind die beiden Gehäuseschalen mit Verbindungsmitteln ausgeführt, mit denen die beiden Gehäuseschalen nach dem Verschwenken zueinander verbunden werden können. Die Verbindungsmittel können auf unterschiedliche Weise realisiert sein, beispielsweise durch korrespondierende Aussparungen und Eingriffe. Die Verbindungsmittel sind bevorzugt als Schnappverbindungsmittel ausgeführt. Besonders bevorzugt sind die Verbindungsmittel derart ausgeführt, dass die Verbindung der beiden Gehäuseschalen lösbar ist.Particularly preferably, the two housing shells are designed with connecting means with which the two housing shells can be connected to each other after pivoting. The connecting means can be realized in different ways, for example by corresponding recesses and interventions. The connecting means are preferably designed as a snap connection means. Particularly preferably, the connecting means are designed such that the connection of the two housing shells is detachable.
