Description

Die Erfindung betrifft eine Einheit aus isolierenden Versorgungseinsatz und elektrisch leitenden Steckergehäuse nach dem Oberbegriff des Anspruchs 1.The invention relates to a unit made of insulating supply insert and electrically conductive plug housing according to the preamble of claim 1.

Versorgungseinsätze umfassen elektrische Kontakte. Einer dieser elektrischen Kontakte wird benötigt, um einen PE- oder Schutzleiter mit einem elektrisch leitenden Metallgehäuse zu kontaktieren.Supply inserts include electrical contacts. One of these electrical contacts is needed to contact a PE or PE conductor with an electrically conductive metal housing.

Stand der TechnikState of the art

Elektrische Kontakte, die in isolierende Steckereinsätze eines Steckverbinders einzufügen sind, weisen regulär einen Steckbereich und einen Anschlussbereich auf, der als Schraubanschluss, Löt- oder Crimpanschluss ausgebildet ist.Electrical contacts that are to be inserted into insulating plug inserts of a connector, have regularly a plug-in area and a connection area, which is designed as a screw, solder or crimp.

Derartige Kontakte können jedoch nicht eingesetzt werden, wenn, wie bei einer 230 V Arbeitsspannung erforderlich, ein so genannter PE-Kontakt benötigt wird, der für Schutzmaßnahmen gegen gefährliche Körperströme erforderlich ist, um die elektrische Verbindung zu einem geerdeten Punkt einer Stromquelle herzustellen.However, such contacts can not be used if, as required by a 230 V working voltage, a so-called PE contact is required, which is required for protection against dangerous body currents, in order to establish the electrical connection to a grounded point of a power source.

Aus der EP 1 130 688 ist eine Schutzleiterverbindung bekannt, bei der in einem metallischen Rechteckgehäuse ein Isolierkörper mit darin angordneten Kontaktelementen vorgesehen ist, wobei ein seitlich in eine PE-Kontaktkammer einrastbares PE-Kontaktelement nach dem Einsetzen des Isolierkörpers an dem metallische Rechteckgehäuse ausgebildete Kontaktmittel sicher kontaktiert.From the EP 1 130 688 is a protective conductor connection is known in which in a metallic rectangular housing an insulating body is provided with angordneten therein contact elements, wherein a laterally engageable in a PE contact chamber PE contact element after insertion of the insulating body formed on the metallic rectangular housing contact means securely contacted.

Die US 4,291,930 zeigt einen Isolierkörper, der ein PE-Kontaktelement umfasst. Das Kontaktelement wird mit einem separaten Bügel, in Kombination mit einer Schraubverbindung, leitend mit einem Gehäuse eines Steckverbinders verbunden. Eine derartige PE-Kontaktierung ist kompliziert und nicht immer zuverlässig.The US 4,291,930 shows an insulating body comprising a PE contact element. The contact element is connected to a separate bracket, in combination with a screw, conductively connected to a housing of a connector. Such PE contacting is complicated and not always reliable.

Aufgabenstellungtask

Dieser Kontakt wird mit weiteren Kontakten in einem mehrere Hülsen umfassenden, elektrisch isolierenden Versorgungseinsatz positioniert, der vorteilhaft zusammen mit einem Datensteckmodul in einem metallischen Steckergehäuse angeordnet ist.This contact is positioned with further contacts in a multi-core, electrically insulating supply insert, which is advantageously arranged together with a data plug-in module in a metallic connector housing.

Dabei ist der Versorgungseinsatz zur Strom/Spannungsversorgung und das Datensteckmodul zur Übertragung von Signalspannungen vorgesehen. Dabei ist von Vorteil, dass der elektrische Kontakt über seine Gewindebohrung und mittels einer Verschraubung, durchgeführt durch das jeweilige Steckergehäuse, eine direkte Kontaktierung zwischen der Verdickung und einer die Öffnung für die Verschraubung umgebende Erhöhung im Gehäuseinneren des Steckergehäuses ermöglicht.The supply insert for the current / voltage supply and the data plug-in module for the transmission of signal voltages are provided. It is advantageous that the electrical contact via its threaded bore and by means of a screw, performed by the respective connector housing, a direct contact between the thickening and surrounding the opening for the screw increase in the housing interior of the connector housing allows.
