Description

Die Erfindung geht aus von einem Steckverbinder nach dem Oberbegriff des unabhängigen Anspruchs 1.The invention relates to a connector according to the preamble of independent claim 1.

Derartige Steckverbinder und Gegensteckverbinder werden im Stand der Technik verwendet, um eine elektrische und mechanische Verbindung zwischen zwei elektrischen Leitungen oder einer elektrischen Leitung und einem Gerät oder einer Installation herzustellen. Insbesondere für die Übertragung großer Ströme sind große, schwere Steckverbinder erforderlich, die durch das Gehäuse gegen Umwelteinflüsse geschützt sind.Such connectors and mating connectors are used in the prior art to provide an electrical and mechanical connection between two electrical leads or an electrical lead and a device or installation. In particular, for the transmission of large currents large, heavy connectors are required, which are protected by the housing against environmental influences.

Derartige Gehäuse bestehen üblicherweise aus Aluminium und sind mit einem Gewinde zur Aufnahme einer Kabelverschraubung versehen. Die hier betrachteten Steckverbinder sind zur Verbindung von einer Mehrzahl elektrischer Leiter ausgeführt, von denen einer ein Schutzleiter (PE-Kontakt) ist. Der Schutzleiter kann auch kombiniert mit einem Neutralleiter als PEN-Kontakt ausgeführt sein. Der Schutzleiter ist mit der Schutzleiterbrücke verbunden, um eine entsprechende Schutzleiterfunktion zu ermöglichen und die Schutzleiter von Steckverbinder und Gegensteckverbinder miteinander in Kontakt zu bringen. Die übrigen Leiter sind mit elektrischen Kontakten des Steckereinsatzes verbunden.Such housings are usually made of aluminum and are provided with a thread for receiving a cable gland. The connectors considered here are designed for connection of a plurality of electrical conductors, one of which is a protective conductor (PE contact). The protective conductor can also be combined with a neutral conductor as a PEN contact. The protective conductor is connected to the protective conductor bridge in order to enable a corresponding protective conductor function and to bring the protective conductors of the connector and the mating connector into contact with one another. The remaining conductors are connected to electrical contacts of the plug insert.

Der prinzipielle Aufbau von Steckverbinder und Gegensteckverbinder kann im Wesentlichen identisch sein und sich lediglich in der Ausgestaltung ihrer elektrischen Kontakte zum Herstellen der elektrischen Verbindung unterscheiden. Die Ausführungen für den Steckverbinder gelten somit entsprechend für den Gegensteckverbinder.The basic structure of connector and mating connector may be substantially identical and differ only in the design of their electrical contacts for making the electrical connection. The designs for the connector thus apply accordingly for the mating connector.

Steckverbinder und Gegensteckverbinder sind korrespondierend nach dem Stecker-Buchse-Prinzip zur Herstellung einer elektrischen Verbindung zwischen dem Steckverbinder und dem Gegensteckverbinder ausgeführt. Die elektrischen Kontakte von Steckverbinder und Gegensteckverbinder können jeweils korrespondierend als Kontaktstifte oder Kontaktstiftaufnahmen ausgeführt sein. Zur sicheren elektrischen Verbindung der Leiter von Steckverbinder und Gegensteckverbinder ist der Steckereinsatz fest an dem Gehäuse positioniert.Connector and mating connector are designed according to the male-female principle for establishing an electrical connection between the connector and the mating connector. The electrical contacts of the connector and the mating connector may each be designed correspondingly as contact pins or pin receptions. For secure electrical connection of the conductors of connector and mating connector of the plug insert is firmly positioned on the housing.

Stand der TechnikState of the art

Aus der DE 203 30 11 A ist ein solcher Schutzkontaktstecker mit einem in einem Steckermantel angeordneten Steckereinsatz bekannt, bei dem der Schutzkontakt unmittelbar an dem Kontaktträger des Steckereinsatzes befestigt ist.From the DE 203 30 11 A is such a grounded plug with a plug shell arranged in a plug insert is known in which the earthing contact is attached directly to the contact carrier of the plug insert.

Aus der DE 10 2005 019 245 B3 sind eine elektrische Steckvorrichtung nach EN 60 309 und eine Schutzkontaktsteckvorrichtung bestehend aus einem Kontaktträger und einem Umgehäuse bekannt. Das Umgehäuse dient zur Aufnahme und Befestigung des Kontaktträgers, der Rastelemente aufweist die beim axialen Einschieben in das Umgehäuse eine gerastete, kraft- und oder formschlüssige Verbindung mit dem Umgehäuse herstellen. Durch das Betätigen von einem oder mehreren Entriegelungselementen, die sich am Umgehäuse befinden, kann die Verrastung wieder gelöst werden.From the DE 10 2005 019 245 B3 are an electrical connector according to EN 60 309 and a safety contact device consisting of a contact carrier and a surrounding housing known. The surrounding housing serves to receive and fasten the contact carrier, which has the latching elements when latched axially into the surrounding housing to produce a latched, frictional and / or positive connection with the surrounding housing. By pressing one or more unlocking elements, which are located on the surrounding housing, the latching can be released again.

Nachteilig an dem zuvor beschriebenen Steckverbinder ist, dass die Montage der Schutzleiterbrücke und des Steckereinsatzes aufwändig ist und in dem Gehäuse Montageraum freigehalten werden muss, um sowohl den Steckereinsatz wie auch die Schutzleiterbrücke zu montieren. Dadurch ist es erforderlich, den Steckverbinder entsprechend groß auszuführen. Außerdem sind derartige Steckverbinder oft schwer, was ihre Handhabung erschwert.A disadvantage of the connector described above, that the mounting of the protective conductor bridge and the plug insert is complex and must be kept free in the housing mounting space to mount both the plug insert as well as the protective conductor bridge. This makes it necessary to make the connector correspondingly large. In addition, such connectors are often heavy, making their handling difficult.

Ausgehend von diesen Nachteilen bietet die DE 10 2012 101 813 B3 einen Steckverbinder der oben genannten Art, der einfach und kosteneffizient herzustellen ist, leicht zu handhaben ist und eine sichere mechanische und elektrische Verbindung von Steckverbinder und Gegensteckverbinder ermöglicht.Based on these disadvantages offers the DE 10 2012 101 813 B3 a connector of the above-mentioned type, which is simple and cost-effective to manufacture, easy to handle and allows a secure mechanical and electrical connection of connector and mating connector.

DE 20 2009 007276 U1 offenbart einen Steckverbinder nach dem Oberbegriff des unabhängigen Anspruchs 1. DE 20 2009 007276 U1 discloses a connector according to the preamble of independent claim 1.

Zudem soll die Stabilität des Steckereinsatzes im Steckverbinder erhöht werden.In addition, the stability of the connector insert in the connector should be increased.

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.

Die Erfindung betrifft einen Steckverbinder zur mechanischen und elektrischen Verbindung mit einem korrespondierenden Gegensteckverbinder. Dabei können Steckverbinder und Gegensteckverbinder identisch ausgebildet sein. Der Steckverbinder kann sowohl Kabelsteckverbinder, zur Verbindung mit einem Kabel, oder als Anbausteckverbinder zur Montage an einer Gerätewand vorgesehen sein.The invention relates to a connector for mechanical and electrical connection with a corresponding mating connector. In this case, plug connectors and mating connectors can be identical. The connector can be provided both cable connector for connection to a cable, or as Anba connector for mounting on a device wall.

Der Steckverbinder besteht aus einem Gehäuse in welchem ein Halterahmen aufgenommen ist. Der Halterahmen dient zur Aufnahme eines Steckereinsatzes. Der Steckereinsatz ist zur elektrischen Kontaktierung mit einem korrespondierenden Steckereinsatz des Gegensteckverbinders vorgesehen.The connector consists of a housing in which a holding frame is added. The holding frame serves to receive a plug insert. The plug insert is provided for electrical contacting with a corresponding plug insert of the mating connector.

Zudem ist im Steckverbinder eine Schutzleiterbrücke vorgesehen, welche zur Verbindung der Schutzleiter (PE-Kontakte) des Steckereinsatzes dient. Dazu ist die Schutzleiterbrücke erfindungsgemäß seitlich in den Halterahmen eingesetzt. Zweckmäßig ist die Schutzleiterbrücke aus einem elektrisch leitfähigen Material hergestellt. Eine besonders bevorzugte Ausführung der Schutzleiterbrücke sieht vor, diese aus Metallblech herzustellen. Dies ist besonders flexibel, leicht zu bearbeiten und kostengünstig herzustellen.In addition, a protective conductor bridge is provided in the connector, which serves to connect the protective conductor (PE contacts) of the plug insert. For this purpose, the protective conductor bridge according to the invention is inserted laterally into the holding frame. Suitably, the protective conductor bridge is made of an electrically conductive material. A particularly preferred embodiment of the protective conductor bridge provides to produce these from sheet metal. This is particularly flexible, easy to work with and inexpensive to manufacture.

Um den Steckereinsatz im Halterahmen befestigen zu können ist am Halterahmen wenigstens ein Verbindungsbereich vorgesehen. An diesem wenigstens einen Verbindungsbereich kann der Steckereinsatz am Halterahmen gehalten werden. Zweckmäßig ist der Verbindungsbereich am Halterahmen so ausgestaltet, dass der Steckereinsatz mittels einer Schraubverbindung am Halterahmen befestigt werden kann.In order to be able to fasten the plug insert in the holding frame, at least one connecting region is provided on the holding frame. At this at least one connection region of the plug insert can be held on the support frame. Suitably, the connection area on the support frame is designed so that the plug insert can be fastened by means of a screw on the support frame.

Erfindungsgemäß weist hierzu der Verbindungsbereich am Halterahmen ein Durchgangsloch auf, in welches eine Schraube eingesetzt werden kann.

For this purpose, the through hole is provided on its inside with an internal thread.

In einer besonderen Ausführungsform ist in den Verbindungsbereich des Halterahmens eine Hülse eingesetzt, welche als Schraubhülse ausgebildet ist. Diese Schraubhülse ist verdrehsicher im Verbindungsbereich eingebracht. Eine Schraube, mit welcher ein Steckereinsatz am Halterahmen befestigt wird, kann so in die Schraubhülse im Verbindungsbereich eingeschraubt werden. Besonders zweckmäßig ist die Ausführung der Schraubhülse aus Metall um eine sichere Befestigung und Verschraubung zu gewähren.In a particular embodiment, a sleeve is used in the connection region of the holding frame, which is designed as a screw sleeve. This screw is inserted against rotation in the connection area. A screw with which a plug insert is fastened to the holding frame can thus be screwed into the screw sleeve in the connection region. Particularly useful is the execution of the threaded sleeve made of metal to grant a secure attachment and screwing.

Erfindungsgemäß weist die Schutzleiterbrücke zumindest eine Lasche auf, wobei die Lasche über ein Durchgangsloch verfügt. Das Durchgangsloch ist so in der Lasche vorgesehen, dass das Durchgangsloch kreissymmetrisch zum Durchgangsloch des Verbindungsbereichs des Halterahmens liegt.According to the invention, the protective conductor bridge has at least one tab, wherein the tab has a through-hole. The through hole is provided in the tab so that the Through hole is circular symmetrical to the through hole of the connecting portion of the holding frame is located.

Dazu ist die Lasche vorzugsweise in einen Schlitz eingesetzt, welcher quer zum Durchgangsloch des Verbindungsbereichs ausgerichtet ist. Dadurch liegt die Lasche ebenfalls quer zum Durchgangsloch des Verbindungsbereichs und die Durchgangslöcher können fluchtend, kreissymmetrisch ausgerichtet werden.For this purpose, the tab is preferably inserted into a slot which is aligned transversely to the through hole of the connecting region. As a result, the tab is also transverse to the through hole of the connection region and the through holes can be aligned in a circle-symmetrical manner.

In einer besonders bevorzugten Ausführungsform ist an der Schutzleiterbrücke wenigstens ein Paar von zwei parallelen Laschen vorgesehen. Dabei verfügen beide Laschen über jeweils ein Durchgangsloch, wobei die Durchgangslöcher der Laschen kreissymmetrisch angeordnet sind.In a particularly preferred embodiment, at least one pair of two parallel tabs is provided on the protective conductor bridge. In this case, both tabs each have a through hole, wherein the through holes of the tabs are arranged circular symmetrical.

Bei dieser Ausführungsform ist zumindest einer der beiden Laschen in einem Schlitz im Halterahmen vorgesehen. Die zweite Lasche ist dabei so auf dem Verbindungsbereich angeordnet, dass die den Steckereinsatz kontaktiert. Durch aufschrauben des Steckereinsatzes auf den Verbindungsbereich wird so eine elektrisch leitende Verbindung zwischen dem Steckereinsatz und der Schutzleiterbrücke hergestellt.In this embodiment, at least one of the two tabs is provided in a slot in the holding frame. The second tab is arranged on the connection area that contacts the plug insert. By screwing the plug insert on the connection area as an electrically conductive connection between the plug insert and the protective conductor bridge is made.

Eine weiterführende Ausführungsform sieht vor, dass die Schraubhülse so im Verbindungsbereich des Halterahmens vorgesehen sein, dass sie zumindest ein Durchgangsloch einer Lasche durchdringt. Besonders zweckmäßig ist die Schraubhülse durch das Durchgangsloch der Lasche zu führen, die in den Schlitz im Halterahmen eingesetzt ist. So kann die Lasche in den Schlitz eingesetzt und anschließend mittels der Schraubhülse, welche das Durchgangsloch durchdringt, vor Herausfallen gesichert werden.A further embodiment provides that the threaded sleeve be provided in the connecting region of the holding frame, that it penetrates at least one through hole of a tab. Particularly expedient, the screw is to pass through the through hole of the tab, which is inserted into the slot in the support frame. Thus, the tab can be inserted into the slot and then secured by means of the threaded sleeve, which penetrates the through hole, from falling out.

In einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung weist die Schutzleiterbrücke zwei Paare Laschen auf. Dabei sind die Paare Laschen an den Endbereichen der länglich ausgebildeten Schutzleiterbrücke vorgesehen. Dementsprechend verfügt, in dieser Ausführungsform, der Halterahmen über zwei Verbindungsbereiche, in welchen die Laschen eingesetzt werden können.In a further preferred embodiment of the present invention, the protective conductor bridge has two pairs of tabs. The pairs of tabs are provided at the end portions of the elongated protective conductor bridge. Accordingly, in this embodiment, the support frame has two connection portions in which the tabs can be inserted.

Erfindungsgemäß verfügt der Halterahmen über Befestigungsmittel die dafür vorgesehen sind, den Halterahmen im Gehäuse des Steckverbinders zu befestigen. Die Befestigungsmittel sind vorzugsweise als Rastmittel ausgeführt. Dadurch kann der Halterahmen im Gehäuse des Steckverbinders verrasten. Korrespondierende Rastmittel im Gehäuse sorgen für eine sichere und dauerhafte Verrastung der Befestigungsmittel des Halterahmens im Gehäuse.According to the invention, the holding frame has fastening means which are provided to secure the holding frame in the housing of the connector. The fastening means are preferably designed as latching means. As a result, the holding frame can latch in the housing of the connector. Corresponding locking means in the housing ensure a secure and permanent locking of the fastening means of the holding frame in the housing.

In einer bevorzugten Ausführungsform sind am Halterahmen mehrere Befestigungsmittel in gegenüberliegende Ausrichtungen vorgesehen. Durch die entgegengesetzt ausgerichteten Befestigungsmittel wird bei Gehäusen die als Anbaugehäuse ausgebildet sind noch ein weiterer, positiver Effekt ermöglicht. Anbaugehäuse sind dabei Gehäuse die nicht über einen Kabelabgang verfügen, sondern an eine Gehäuse- oder Gerätewand anbringbar sind.In a preferred embodiment, a plurality of fastening means are provided in opposite orientations on the holding frame. Due to the oppositely oriented fastening means, a further positive effect is made possible in the case of housings which are designed as mounting housings. Attachment housings are housings that do not have a cable outlet, but can be attached to a housing or device wall.

Bei diesen Gehäuse kann durch die entgegengesetzt ausgerichteten Befestigungsmittel der Halterahmen von beiden Seiten in das Gehäuse eingesetzte werden. Das heißt sowohl von der Steckseite des Gehäuses als auch von der Anschlussseite.In these cases, by the oppositely directed fastening means of the holding frame can be inserted from both sides in the housing. That means both from the plug side of the housing as well as from the connection side.

Die Vorteile der Erfindung kommen besonders dann zur Geltung, wenn es sich bei dem Gehäuse des Steckverbinders aus einem Gehäuse aus Kunststoff handelt. Hier ist eine Verrastung des Halterahmens, welcher ebenfalls vorzugsweise aus Kunststoff hergestellt ist, besonders vorteilhaft und gut zu realisieren. Die Befestigungsmittel des Halterahmens, sowie die korrespondierenden Rastmittel im Gehäuse stellen eine besonders gute und dauerhafte Verbindung dar, wenn alle Bauteile aus Kunststoff hergestellt sind.The advantages of the invention are particularly evident when it comes to the housing of the connector of a plastic housing. Here, a latching of the holding frame, which is also preferably made of plastic, particularly advantageous and to realize well.
