Description

Steckverbinder mit Schutzleiterbrücke Beschreibung  Connector with protective conductor bridge Description
Die Erfindung geht aus von einem Steckverbinder nach dem Oberbegriff des unabhängigen Anspruchs 1 und weiterhin geht die Erfindung von einem Steckverbinder nach dem Oberbegriff des nebengeordneten Anspruch 1 1 aus.  The invention relates to a connector according to the preamble of independent claim 1 and further, the invention of a connector according to the preamble of the independent claim 1 1 is made.
Derartige Steckverbinder und Gegensteckverbinder werden verwendet, um eine elektrische und mechanische Verbindung zwischen zwei elektrischen Leitungen oder einer elektrischen Leitung und einem Gerät herzustellen. Insbesondere für die Übertragung großer Ströme sind sogenannte schwere Steckverbinder erforderlich, die durch das Gehäuse gegen Umwelteinflüsse geschützt sind. Such connectors and mating connectors are used to establish an electrical and mechanical connection between two electrical leads or an electrical lead and a device. In particular, for the transmission of large currents called heavy connectors are required, which are protected by the housing against environmental influences.
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.
Stand der Technik State of the art
Die Druckschrift WO 201 1 /069522 A1 offenbart einen Systemsteckverbinder, der Steck-Module mit darin gehaltenen elektrischen Kontakten aufnimmt. Die Steck-Module werden senkrecht in einen Bereich eines Halterahmens eingesetzt und anschließend seitlich um 90° in den Halterahmen verschoben und gehalten.  The publication WO 201 1/069522 A1 discloses a system connector which receives plug-in modules with electrical contacts held therein. The plug-in modules are inserted vertically into a region of a holding frame and then laterally displaced and held by 90 ° in the holding frame.
Aus der Druckschrift DE 203 30 1 1 A ist ein Schutzkontaktstecker mit einem in einem Steckermantel angeordneten Steckereinsatz bekannt, bei dem der Schutzkontakt unmittelbar an dem Kontaktträger des Steckereinsatzes befestigt ist. Die Druckschrift DE 10 2014 109 351 B3 bietet einen Steckverbinder, der eine sichere mechanische und elektrische Verbindung von Steckverbinder und Gegensteckverbinder ermöglicht. From the publication DE 203 30 1 1 A is a safety plug with a plug shell arranged in a plug insert is known in which the protective contact is attached directly to the contact carrier of the plug insert. The document DE 10 2014 109 351 B3 provides a connector that allows a secure mechanical and electrical connection of connectors and mating connectors.
Aus der DE 10 2012 101 813 B3 ist ein Steckverbinder mit einem Steckereinsatz und einer Schutzleiterbrücke bekannt. Dabei ist der Steckereinsatz an einem Verbindungsbereich gehalten, welcher als Schraubverbindung ausgeführt ist. From DE 10 2012 101 813 B3 a connector with a plug insert and a protective conductor bridge is known. In this case, the plug insert is held on a connection region, which is designed as a screw connection.
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 besitzen derartige Steckverbinder oft ein hohes Gewicht, 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 often have a high weight, which makes their handling difficult.

Das Gehäuse 2 verfügt über vier Verbindungsbereiche 9. In der Figur 2 sind von den vier Verbindungsbereichen auf Grund der perspektivischen Darstellung nur zwei Verbindungsbereiche 9 zu sehen. Der Verbindungsbereich 9 weist ein Durchgangsloch auf, welches über ein Innengewinde verfügt. Das Durchgangsloch des Verbindungsbereichs 9 wird in dieser Figur von der Abwinkelung 14 und dem dazugehörigen Durch- gangsloch 13 verdeckt. FIG. 2 shows a perspective view of a housing 2 of a connector 1. The housing 2 is a plastic housing. The housing 2 has four connection regions 9. In FIG. 2, only two connection regions 9 can be seen from the four connection regions due to the perspective illustration. The connecting portion 9 has a through hole which has an internal thread. The through-hole of the connecting region 9 in this figure is defined by the bend 14 and the associated through-hole. hole 13 is covered.
In dem Gehäuse 2 ist die Schutzleiterbrücke 3 aus der Figur 1 eingesetzt. Die Schutzleiterbrücke 3, genauer die Lasche 12 der Schutzleiterbrücke 3, ist dabei in einem Schlitz angeordnet. Die Lasche 2 weist die Länge des Innenmaßes des Gehäuses 2 auf. Das Durchgangsloch des Verbindungsbereiches 9 und das Durchgangsloch 13 sind kreissymmetrisch und fluchtend zueinander ausgerichtet. Dadurch sind die Abwinkelung 14 und der Verbindungsbereich 9 ebenfalls parallel zueinander ausgerichtet, während sich die Lasche 12 senkrecht dazu befindet. In the housing 2, the protective conductor bridge 3 is inserted from the figure 1. The protective conductor bridge 3, more precisely the tab 12 of the protective conductor bridge 3, is arranged in a slot. The tab 2 has the length of the inner dimension of the housing 2. The through hole of the connection portion 9 and the through hole 13 are circularly symmetrical and aligned with each other. As a result, the angled portion 14 and the connecting portion 9 are also aligned parallel to each other, while the tab 12 is perpendicular thereto.
Die Figur 3 zeigt eine perspektivische Darstellung eines Halterahmens 4. Dieser ist in ein Gehäuse eines Steckverbinders 1 einsetzbar. Der Halterahmen 4 wird vorrangig in Kombination mit einem Anbaugehäuse eingesetzt. Der Halterahmen 4 besteht aus Kunststoff. 3 shows a perspective view of a holding frame 4. This is in a housing of a connector 1 can be used. The support frame 4 is used primarily in combination with a mounting housing. The support frame 4 is made of plastic.
Der Halterahmen 4 verfügt über vier Verbindungsbereiche 9. Jeder dieser Verbindungsbereiche 9 weist ein Durchgangsloch auf mit je einem Innengewinde auf. The holding frame 4 has four connecting regions 9. Each of these connecting regions 9 has a through hole with an internal thread.
In dem Halterahmen 4 ist die Schutzleiterbrücke 3 aus der Figur 1 eingesetzt. Die Schutzleiterbrücke 3, genauer die Lasche 12 der Schutzleiterbrücke 3, ist dabei in einem Schlitz angeordnet. Die Lasche 12 weist die Länge des Innenmaßes des Gehäuses 2 auf. Das Durchgangsloch des Verbindungsbereiches 9 und das Durchgangsloch 13 sind kreissymmetrisch und fluchtend zueinander ausgerichtet.

Steckverbinder mit Schutzleiterbrücke In the support frame 4, the protective conductor bridge 3 is inserted from the figure 1. The protective conductor bridge 3, more precisely the tab 12 of the protective conductor bridge 3, is arranged in a slot. The tab 12 has the length of the inner dimension of the housing 2. The through hole of the connection portion 9 and the through hole 13 are circularly symmetrical and aligned with each other. As a result, the angled portion 14 and the connecting portion 9 are also aligned parallel to each other, while the tab 12 is perpendicular thereto. Connector with protective conductor bridge
