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 7 aus.The invention is based on a connector according to the preamble of independent claim 1 and the invention is also based on a connector according to the preamble of independent claim 7.

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 lines or an electrical line and a device. So-called heavy-duty connectors, which are protected against environmental influences by the housing, are required in particular for the transmission of large currents.

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 can be essentially identical and differ only in the design of their electrical contacts for establishing the electrical connection. The explanations for the connector apply accordingly to the mating connector.

Stand der TechnikState of the art

Die Druckschrift WO 2011/069522 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 pamphlet WO 2011/069522 A1 discloses a system connector that receives plug-in modules with electrical contacts held therein. The plug-in modules are inserted vertically into an area of a holding frame and then shifted laterally by 90 ° into the holding frame and held.

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

Die Druckschrift DE 10 2014 109 351 B3 bietet einen Steckverbinder, der eine sichere mechanische und elektrische Verbindung von Steckverbinder und Gegensteckverbinder ermöglicht.The pamphlet DE 10 2014 109 351 B3 offers a connector that enables a secure mechanical and electrical connection of connector and mating connector.

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 the DE 10 2012 101 813 B3 a connector with a plug insert and a protective conductor bridge is known. The plug insert is held in a connection area 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.The disadvantage of the connector described above is that the assembly of the protective conductor bridge and the plug insert is complex and assembly space must be kept free in the housing in order to mount both the plug insert and the protective conductor bridge. This makes it necessary to make the connector correspondingly large. In addition, connectors of this type are often very heavy, which makes them difficult to handle.

Die Druckschrift US 2003/008552 A1 offenbart einen kostengünstigen Steckverbinder für die Massenproduktion. Dieser Steckverbinder umfasst einen ersten Stecker, einen zweiten Stecker und ein Verbindungsgehäuse. Jeweils eine Seite des ersten und des zweiten Steckers kann mit einem Computerperipheriegerät (z. B. einer Maus oder einem Modem) eingesteckt werden. Der erste Stecker und der zweite Stecker sind fest mit dem Verbindungsgehäuse verbunden. Das Verbindungsgehäuse ist ein Spritzgussteil aus Kunststoff. Auf dem Verbindungsgehäuse sind mehrere Metallplatten installiert, wobei zwei der Metallplatten mit der Verbindungsfläche des Verbindungsgehäuses verbunden sind. Die Metallplatte auf dem Verbindungsgehäuse hat einen Leitungseffekt, so dass elektrostatische Ladungen von einer Leiterplatte effektiv abgeführt werden können, eine stabile Datenübertragung mit den Computerperipheriegeräten zu gewährleisten.The pamphlet US 2003/008552 A1 discloses an inexpensive connector for mass production. This connector includes a first connector, a second connector and a connector housing. One side of each of the first and second connectors can be plugged in with a computer peripheral device (e.g. a mouse or a modem). The first connector and the second connector are firmly connected to the connection housing. The connection housing is an injection molded part made of plastic. A plurality of metal plates are installed on the connection box, and two of the metal plates are connected to the connection surface of the connection box. The metal plate on the junction box has a conduction effect so that electrostatic charges can be effectively dissipated from a circuit board to ensure stable data transmission with the computer peripheral devices.

AufgabenstellungTask

Die Aufgabe der Erfindung besteht darin, einen Steckverbinder vorzustellen, der einfach zu handhaben ist.The object of the invention is to present a connector that is easy to use.

Die Aufgabe wird durch den Gegenstand der unabhängigen Ansprüche gelöst.The object is achieved by the subject matter of the independent claims.

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

Die Erfindung betrifft einen Steckverbinder zur mechanischen und elektrischen Verbindung mit einem korrespondierenden Gegensteckverbinder, aufweisend ein Gehäuse und eine Schutzleiterbrücke. Das Gehäuse weist wenigstens einen Verbindungsbereich zur Verbindung mit dem Steckereinsatz auf, wobei der Steckereinsatz an dem wenigstens einen Verbindungsbereich gehalten ist. Der Verbindungsbereich und das Gehäuse sind einstückig miteinander ausgeführt. Die Schutzleiterbrücke ist von oben in das Gehäuse einsetzbar. Dadurch ist eine Montage eines Steckereinsatzes von der Steckseite und von der Anschlussseite möglich.The invention relates to a connector for mechanical and electrical connection with a corresponding mating connector, having a housing and a protective conductor bridge. The housing has at least one connection area for connection to the plug insert, the plug insert being held on the at least one connection area. The connection area and the housing are made in one piece with one another. The protective conductor bridge can be inserted into the housing from above. This makes it possible to mount a plug insert from the plug-in side and from the connection side.

Der Steckverbinder und der Gegensteckverbinder können identisch ausgebildet sein. Der Steckverbinder kann sowohl Kabelsteckverbinder, zur Verbindung mit einem Kabel, oder als Anbausteckverbinder zur Montage an einer Gerätewand vorgesehen sein.The connector and the mating connector can be designed identically. The connector can be provided both as a cable connector for connection to a cable or as a built-on connector for mounting on a device wall.

Der Steckverbinder besteht aus einem Gehäuse, welches zur Aufnahme eines Steckereinsatzes dient. Der Steckereinsatz ist zur elektrischen Kontaktierung mit einem korrespondierenden Steckereinsatz des Gegensteckverbinders vorgesehen.The connector consists of a housing which is used to accommodate a connector insert. The plug insert is provided for making electrical contact with a corresponding plug insert of the mating connector.

Zudem ist im Steckverbinder eine Schutzleiterbrücke vorgesehen, welche zur elektrischen Verbindung der Schutzleiter (PE-Kontakte) des Steckereinsatzes dient. Dazu ist die Schutzleiterbrücke erfindungsgemäß von oben in das Gehäuse einsetzbar. Dies bietet den Vorteil, dass die mechanische Stabilität zwischen Gehäuse und Schutzleiterbrücke messbar größer ist als wenn die Schutzleiterbrücke seitlich in das Gehäuse eingesetzt ist.In addition, a protective conductor bridge is provided in the connector, which is used for the electrical connection of the protective conductor (PE contacts) of the plug insert. For this purpose, according to the invention, the protective conductor bridge can be inserted into the housing from above. This offers the advantage that the mechanical stability between the housing and the protective conductor bridge is measurably greater than when the protective conductor bridge is inserted into the side of the housing.

Dabei ist der wenigstens eine Verbindungsbereich zur Herstellung einer Schraubverbindung mit dem Steckereinsatz ausgeführt. Dies bedeutet, dass der Verbindungsbereich so ausgebildet ist, dass er eine Verbindung mit dem Steckereinsatz mittels einer Verschraubung eingehen kann. So kann der Steckereinsatz sicher an dem Gehäuse befestigt werden.The at least one connection area is designed to produce a screw connection with the plug insert. This means that the connection area is designed in such a way that it connects to the plug insert by means of a screw connection can. The plug insert can thus be securely attached to the housing.

Der wenigstens eine Verbindungsbereich weist ein Durchgangsloch auf. In dieses Durchgangsloch des Verbindungsbereichs kann eine Schraube zur Befestigung eingesetzt werden.The at least one connection area has a through hole. A screw for fastening can be inserted into this through hole of the connection area.

Das Durchgangsloch des Verbindungsbereichs weist ein Innengewinde auf. Dieses befindet sich an der Innenseite des Durchgangsloches.The through hole of the connection area has an internal thread. This is located on the inside of the through hole.

In einer weiteren alternativen Ausführungsform ist im Verbindungsbereich eine Schraubhülse in das Gehäuse eingesetzt. Diese Schraubhülse ist verdrehsicher im Verbindungsbereich eingebracht. Eine Schraube, mit welcher der Steckereinsatz am Gehäuse befestigt wird, kann so in die Schraubhülse im Verbindungsbereich eingeschraubt werden.In a further alternative embodiment, a screw sleeve is inserted into the housing in the connection area. This screw sleeve is inserted in the connection area so that it cannot rotate. A screw with which the plug insert is attached to the housing can be screwed into the screw sleeve in the connection area.

In einer vorteilhaften Ausführungsform ist die Schraubhülse aus Metall gefertigt. Dies gewährleistet eine sichere, stabile Befestigung und Verschraubung.In an advantageous embodiment, the screw sleeve is made of metal. This ensures a secure, stable fastening and screw connection.

Die Schutzleiterbrücke weist wenigstens eine Lasche mit mindestens einer Abwinkelung auf. Idealerweise weist die Lasche zwei Abwinklungen auf. Die Abwinkelung weist etwa einen rechten Winkel zur Lasche auf. Bei mehr als einer Abwinkelung weisen die Abwinklungen immer in dieselbe Richtung.The protective conductor bridge has at least one tab with at least one bend. Ideally, the tab has two bends. The bend is approximately at right angles to the tab. If there is more than one bend, the bends always point in the same direction.

Die Abwinkelung weist ein Durchgangsloch auf, wobei das Durchgangsloch kreissymmetrisch zum Durchgangsloch des Verbindungsbereiches liegt.The angled portion has a through hole, the through hole being circularly symmetrical to the through hole of the connecting area.

In einer besonders bevorzugten Ausführungsform ist die wenigstens eine Lasche der Schutzleiterbrücke in einem Schlitz im Gehäuse angeordnet. In dem Schlitz liegt die Lasche senkrecht zum Durchgangsloch des Verbindungsbereichs. Die Abwinkelung liegt parallel zum Durchgangsloch des Verbindungsbereichs. So können die Durchgangslöcher fluchtend, kreissymmetrisch ausgerichtet werden.In a particularly preferred embodiment, the at least one tab of the protective conductor bridge is arranged in a slot in the housing. In the slot, the tab is perpendicular to the through hole of the connecting area. The bend is parallel to the through hole of the connection area. In this way, the through holes can be aligned with circular symmetry.

Zweckmäßig ist die Schutzleiterbrücke aus einem elektrisch leitfähigen Material hergestellt. In einer weiteren, besonders bevorzugten Ausführungsform ist die Schutzleiterbrücke einteilig aus Metall, bevorzugt aus einem Metallblech, hergestellt. Dies ist besonders flexibel, leicht zu bearbeiten und kostengünstig herzustellen. Das Metallblech kann in Stanz-Biege-Technik bearbeitet werden.The protective conductor bridge is expediently made from an electrically conductive material. In a further, particularly preferred embodiment, the protective conductor bridge is made in one piece from metal, preferably from a metal sheet. This is particularly flexible, easy to process and inexpensive to manufacture. The sheet metal can be processed using the punching and bending technique.

In einer vorteilhaften Ausführungsform weist das Gehäuse mindestens eine Rastnase zur Fixierung der Schutzleiterbrücke auf. Die Rastnase dient als zusätzliche Stabilisierungs- und provisorische Fixierungsmöglichkeit für die Schutzleiterbrücke, insbesondere zur Vereinfachung der Montage.In an advantageous embodiment, the housing has at least one latching lug for fixing the protective conductor bridge. The locking lug serves as an additional stabilization and provisional fixation option for the protective conductor bridge, in particular to simplify assembly.

Die Vorteile der Erfindung kommen besonders gut zur Geltung, wenn es sich bei dem Gehäuse um ein aus Kunststoff hergestelltes Gehäuse handelt.The advantages of the invention come into their own when the housing is made of plastic.

In einer alternativen Ausführungsform ist ein Halterahmen zur Aufnahme eines Steckereinsatzes in dem Gehäuse einsetzbar. Der Halterahmen ist am Gehäuse fixiert. Der Einsatz eines Halterahmens ist vorteilhaft, wenn es sich bei dem Gehäuse um ein sogenanntes Anbaugehäuse handelt.In an alternative embodiment, a holding frame for receiving a plug insert can be used in the housing. The holding frame is fixed to the housing. The use of a holding frame is advantageous if the housing is a so-called add-on housing.

In einer bevorzugten Ausführungsform ist der Halterahmen zur Aufnahme der Schutzleiterbrücke geeignet. Er weist dafür mindestens einen einstückigen Verbindungsbereich auf. Dieser entspricht in seiner Form und Ausgestaltung dem Verbindungsbereich des Gehäuses. Der Verbindungsbereich des Halterahmens ist eine Verlängerung des Verbindungsbereiches des Gehäuses.In a preferred embodiment, the holding frame is suitable for receiving the protective conductor bridge. For this purpose, it has at least one one-piece connection area. This corresponds in its form and design the connection area of the housing. The connection area of the holding frame is an extension of the connection area of the housing.

In einer Ausführungsform ist der Halterahmen aus Kunststoff hergestellt. Wird ein Halterahmen mit dem Gehäuse verwendet, so verfügt dieser ebenfalls über entsprechende Durchgangslöcher für die Verbindungsbereiche und über entsprechende Schlitze. Dadurch kann die erfindungsgemäße Schutzleiterbrücke entsprechend auch mit einem Halterahmen verwendet werden, wenn dies erforderlich ist.In one embodiment, the holding frame is made of plastic. If a holding frame is used with the housing, it also has corresponding through holes for the connection areas and corresponding slots. As a result, the protective conductor bridge according to the invention can also be used accordingly with a holding frame, if this is necessary.

Die vorliegende Erfindung löst die erfindungsgemäße Aufgabe durch eine Schutzleiterbrücke, welche einfach von oben in das Gehäuse eines Steckverbinders zu montieren ist. Dadurch gewährleistet die Schutzleiterbrücke eine hohe mechanische Stabilität, besonders hinsichtlich der Steck- und Ziehkräfte. Ferner ermöglicht sie eine einfache, schnelle und preisgünstige Montage.The present invention solves the problem according to the invention by means of a protective conductor bridge which can be easily mounted from above into the housing of a connector. In this way, the protective conductor bridge ensures a high level of mechanical stability, particularly with regard to the insertion and removal forces. It also enables simple, quick and inexpensive assembly.
