Description

Die Erfindung betrifft einen Steckverbinder gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a connector according to the preamble of patent claim 1.

Bekannt sind Steckverbinder für mehradrige Daten und/oder Telekommunikationskabel, welche ein abschirmendes Gehäuse aufweisen. Dabei sind bekannte Gehäuse aus einer oberen Gehäuseschale und einer unteren Gehäuseschale zusammengefügt, wobei in der unteren Gehäuseschale ein Kontaktträger angeordnet ist, welcher Verbinderkontakte für die Steckverbindung und mit diesen Verbinderkontakten leitend verbundene Schneidklemmkontakte für die Adern des Kabels aufweist. In der oberen Gehäuseschale ist ein Ladestück angeordnet, welches Aufnahmen für die Adern des Kabels aufweist, wobei beim Zusammenfügen der Gehäuseschalen die Schneidklemmkontakte des Kontaktträgers in die Adern eindringen. Dadurch wird der elektrisch leitende Kontakt zwischen den Adern des Kabels und den Verbinderkontakten für die Steckverbindung hergestellt. Ein derartiger Steckverbinder ist beispielsweise der DE 100 57 833 A1 zu entnehmen.Connectors for multi-core data and / or telecommunication cables, which have a shielding housing, are known. In this case, known housing composed of an upper housing shell and a lower housing shell, wherein in the lower housing shell a contact carrier is arranged, which connector contacts for the connector and with these connector contacts conductively connected insulation displacement contacts for the wires of the cable. In the upper housing shell, a charging piece is arranged, which has receptacles for the wires of the cable, wherein the insulation displacement contacts of the contact carrier penetrate into the wires during assembly of the housing shells. Thereby, the electrically conductive contact between the wires of the cable and the connector contacts for the connector is made. Such a connector is for example the DE 100 57 833 A1 refer to.

Je nach Anwendung ist ein isolierter Einbau der Steckverbinder in verschiedenen Komponenten einer größeren Anlage von Nöten. Dabei ist es bekannt, die untere Gehäuseschale gezielt mit einem Ausgleichspotential zu verbinden. Diese Verbindung wird beispielsweise über Steckverbinder, Schraubkontakte oder Federkontakte hergestellt. Beim Auswechseln der unteren Gehäuseschale ist es dann jedoch nötig, zusätzlich den Potentialausgleichskontakt zu trennen und an der neuen unteren Gehäuseschale wieder anzuschließen. Dies stellt jedoch einen zusätzlichen Aufwand für den Benutzer und eine potentielle Fehlerquelle dar, da vergessen werden kann, den Potentialausgleichskontakt wieder zu schließen.Depending on the application, an isolated installation of the connectors in different components of a larger system is required. It is known to selectively connect the lower housing shell with a compensation potential. This connection is made for example via connectors, screw contacts or spring contacts. When replacing the lower housing shell, however, it is then necessary to additionally separate the equipotential bonding contact and reconnect to the new lower housing shell. However, this adds extra effort to the user and a potential source of error because it can be forgotten to close the equipotential bonding contact again.

Die Aufgabe der Erfindung besteht daher darin, einen Steckverbinder für mehradrige Daten und/oder Telekommunikationskabel bereitzustellen, welcher einfacher zu handhaben ist.The object of the invention is to provide a connector for multi-core data and / or telecommunications cable, which is easier to handle.

Die Aufgabe wird gelöst durch einen Steckverbinder mit den Merkmalen des Schutzanspruchs 1.The object is achieved by a connector with the features of the protection claim. 1

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Bei dem erfindungsgemäßen Steckverbinder ist an der oberen Gehäuseschale ein Potentialausgleichskontakt angeordnet. Dadurch ist beim Wechseln der unteren Gehäuseschale des Steckverbinders kein Trennen des Potentialausgleichkontakts erforderlich. Der Potentialausgleichskontakt bleibt mit der oberen Gehäuseschale verbunden, so dass einerseits der zusätzliche Schritt des Trennens und wieder neu Verbindens des Potentialausgleichskontakts entfällt und die erneute Herstellung der Verbindung bei der Montage nicht vergessen werden kann.Advantageous embodiments and further developments of the invention are specified in the subclaims. In the connector according to the invention, an equipotential bonding contact is arranged on the upper housing shell. As a result, no separation of the equipotential bonding contact is required when changing the lower housing shell of the connector. The potential equalization contact remains connected to the upper housing shell, so that on the one hand eliminates the additional step of disconnecting and reconnecting the equipotential bonding contact and the re-production of the connection during assembly can not be forgotten.

Bei einer vorteilhaften Weiterbildung der Erfindung ist der Potentialausgleichskontakt als Steckkontakt ausgebildet, so dass er sich falls nötig besonders einfach Verbinden und wieder Trennen lassen kann. Besonders bevorzugt ist dazu der Potentialausgleichskontakt als auf eine Kontaktzunge schiebbarer Flachsteckkontakt ausgebildet, da dieser besonders kostengünstig zu fertigen und einfach zu montieren ist.In an advantageous embodiment of the invention, the equipotential bonding contact is designed as a plug-in contact, so that it can if necessary particularly easy connect and disconnect again. For this purpose, the potential equalization contact is particularly preferably designed as a blade-type contact which can be pushed onto a contact tongue, since it is particularly cost-effective to manufacture and easy to assemble.

In einer besonders vorteilhaften Ausgestaltung der Erfindung ist der Potentialausgleichskontakt derart an der oberen Gehäuseschale angeordnet, dass eine mit dem Potentialausgleichskontakt verbundene Anschlussleitung parallel zu dem Kabel führbar ist. Dies ermöglicht dem Benutzer eine bessere Übersicht über die Zuleitungen zu dem Steckverbinder.In a particularly advantageous embodiment of the invention, the equipotential bonding contact is arranged on the upper housing shell such that one with the equipotential bonding contact connected connection line parallel to the cable is feasible. This allows the user a better overview of the leads to the connector.

Vorzugsweise ist der Potentialausgleichskontakt in räumlicher Nähe zu der Eintrittsöffnung des Kabels in das Ladestück angeordnet, um auch die Anschlussleitung in räumlicher Nähe zu dem Kabel führen zu können.Preferably, the equipotential bonding contact in spatial proximity to the inlet opening of the cable is arranged in the charging piece in order to be able to lead the connecting cable in spatial proximity to the cable.

Vorzugsweise sind die Gehäuseschalen als metallische Druckgussteile ausgebildet, so dass der Potentialausgleich zwischen den beiden Gehäuseschalen über die Verbindungskontakte der beiden Gehäuseschalen, welche beispielsweise als Rastmechanismus ausgebildet sein können, erfolgen kann.Preferably, the housing shells are formed as metallic die-cast parts, so that the potential equalization between the two housing shells on the connection contacts of the two housing shells, which may be formed for example as a latching mechanism, can take place.

Die Figuren 1 bis 4 zeigen verschiedene Ansichten eines Steckverbinders 10 mit einem Gehäuse 20, welches aus einer oberen Gehäuse 30 und einer unteren Gehäuseschale 40 zusammengesetzt ist. Der Steckverbinder 10 dient zum Anschließen eines Kabels 50 mit mehreren Adern 52, insbesondere eines mehradrigen Daten- und/oder Telekommunikationskabels. Dabei ist das Kabel 50 vorzugsweise geschirmt, wozu es insbesondere mit einem leitendes Schirmgeflecht umgeben ist.The FIGS. 1 to 4 show various views of a connector 10 with a housing 20, which composed of an upper housing 30 and a lower housing shell 40 is. The connector 10 is used to connect a cable 50 with multiple wires 52, in particular a multi-core data and / or telecommunication cable. In this case, the cable 50 is preferably shielded, for which purpose it is surrounded in particular by a conductive braided screen.

Die obere Gehäuseschale 30 und die untere Gehäuseschale 40 sind vorzugsweise aus einem elektrisch leitenden Werkstoff gefertigt und insbesondere als metallisches Druckgussteil, beispielsweise als Zinkdruckgussteil hergestellt. Die beiden Gehäuseschalen 30, 40 werden über einen Rastmechanismus zusammengesteckt, wobei an oberen Gehäuseschale 30 zwei Rastvorsprünge 36 angeordnet sind, welche in entsprechende Rastaufnahmen 46 an der unteren Gehäuseschale 40 eingreifen.The upper housing shell 30 and the lower housing shell 40 are preferably made of an electrically conductive material and in particular produced as a metallic die cast part, for example as Zinkdruckgussteil. The two housing shells 30, 40 are plugged together via a latching mechanism, wherein two latching projections 36 are arranged on the upper housing shell 30, which engage in corresponding latching receptacles 46 on the lower housing shell 40.

In der oberen Gehäuseschale 30 ist ein Ladestück 32 angeordnet, welches Aufnahmen 34 zur Aufnahme der Adern 52 des Kabels 50 aufweist sind. Das Kabel 50 wird somit durch eine Eintrittsöffnung in die obere Gehäuseschale 30 und das Ladestück 32 eingeführt, wobei innerhalb der oberen Gehäuseschale die Ummantelung des Kabels 50 entfernt wird, so dass die einzelnen Adern 52 in die Aufnahmen 34 des Ladestücks 32 einlegbar und dort fixierbar sind.In the upper housing shell 30, a charging piece 32 is arranged, which have receptacles 34 for receiving the wires 52 of the cable 50. The cable 50 is thus inserted through an inlet opening in the upper housing shell 30 and the charging piece 32, wherein the sheath of the cable 50 is removed within the upper housing shell, so that the individual wires 52 in the receptacles 34 of the charging piece 32 can be inserted and fixed there ,

In der unteren Gehäuseschale 40 ist ein Kontaktträger 42 angeordnet, welcher Schneidklemmkontakte 44 aufweist, wobei die Anzahl der Schneidklemmkontakte 44 vorzugsweise der Anzahl der Adern 52 des Kabels 50 entspricht. Die Schneidklemmkontakte 44 sind über Verbinderkontakte mit einer Einstecköffnung 48 der unteren Gehäuseschale 40 verbunden, so dass in die Einstecköffnung 48 ein entsprechender Stecker eingesteckt werden kann, um die Verbinderkontakte und die Schneidklemmkontakte 44 zu kontaktieren. Die Schneidklemmkontakte 44 sind dabei derart an dem Kontaktträger 42 angeordnet, dass beim Aufsetzen der oberen Gehäuseschale 30 mit dem Ladestück 32 auf die untere Gehäuseschale 40 die Schneidklemmkontakte 44 in die in den Aufnahmen 34 des Ladestücks 32 liegende Adern 52 des Kabels 50 eindringen und dadurch den elektrischen Kontakt zwischen dem Kabel 50 und einem in die Einstecköffnung 48 eingesteckten Stecker herstellen.In the lower housing shell 40, a contact carrier 42 is arranged, which has insulation displacement contacts 44, wherein the number of insulation displacement contacts 44 preferably corresponds to the number of wires 52 of the cable 50. The insulation displacement contacts 44 are connected via connector contacts with an insertion opening 48 of the lower housing shell 40, so that in the insertion opening 48, a corresponding plug can be inserted to contact the connector contacts and the insulation displacement contacts 44. The insulation displacement contacts 44 are so on the contact carrier 42 arranged that when placing the upper housing shell 30 with the charging piece 32 on the lower housing shell 40, the insulation displacement contacts 44 penetrate into the receptacles 34 of the charging piece 32 wires 52 of the cable 50 and thereby the electrical contact between the cable 50 and make a plugged into the insertion 48 connector.

Je nach Verwendung des Steckverbinders 10 ist es nötig, dass elektrisch leitende Gehäuse 20 isoliert angeordnet werden. Dazu muss dann jedoch die Schirmung des Steckverbinders 10 gezielt mit einem Ausgleichspotential verbunden werden. Dazu ist an der oberen Gehäuseschale 30 ein Potentialausgleichskontakt 60 angeordnet, der vorliegend als Flachsteckkontakt 62 mit einem Kabelschuh 64 ausgebildet ist, welcher über eine an der oberen Gehäuseschale 30 leitend verbundene Kontaktzunge 66 geschoben werden kann. An dem Flachsteckkontakt 62 endet eine entsprechende Anschlussleitung 63 für den Potentialausgleich. Über den Flachsteckkontakt 62 kann in einfacher Art und Weise der Potentialausgleich der oberen Gehäuseschale 30 erfolgen. Da die obere Gehäuseschale 30 mit der unteren Gehäuseschale 40 über eine Rastverbindung aus elektrisch leitendem Material verbunden ist, erfolgt darüber auch der Potentialausgleich für die untere Gehäuseschale 40. Dadurch, dass der Potentialausgleichkontakt 60 an der oberen Gehäuseschale 30 angeordnet ist, muss bei Wechseln der unteren Gehäuseschale 40 der Potentialausgleichskontakt 60 nicht mehr gelöst werden, so dass auch nicht vergessen werden kann, den Potentialausgleichskontakt nach Wechsel der unteren Gehäuseschale 40 wieder zu schließen.Depending on the use of the connector 10, it is necessary that electrically conductive housing 20 are arranged isolated. For this purpose, however, then the shielding of the connector 10 must be selectively connected to a compensation potential. For this purpose, an equipotential bonding contact 60 is arranged on the upper housing shell 30, which in the present case is designed as a flat plug-in contact 62 with a cable lug 64 which can be slid over a contact lug 66 which is conductively connected to the upper housing shell 30. At the flat plug contact 62 ends a corresponding connection line 63 for the equipotential bonding. Via the flat plug contact 62, the equipotential bonding of the upper housing shell 30 can take place in a simple manner. Since the upper housing shell 30 is connected to the lower housing shell 40 via a latching connection made of electrically conductive material, the equipotential bonding for the lower housing shell 40 is also carried out. The fact that the equipotential bonding contact 60 is arranged on the upper housing shell 30, must when changing the lower Housing shell 40 of the equipotential bonding contact 60 are no longer solved, so that it can not be forgotten to close the equipotential bonding contact after changing the lower housing shell 40 again.

Die Kontaktzunge 66 ist vorzugsweise derart an der oberen Gehäuseschale 30 angeordnet, dass die Anschlussleitung 63 in gleicher Richtung wie das Kabel 50 an die obere Gehäuseschale 30 herangeführt werden kann. Die Kontaktzunge 66 kann alternativ auch innerhalb der oberen Gehäuseschale 30 und insbesondere an dem Ladestück 32 angeordnet werden. Dadurch, dass die Zufuhrrichtung für das Kabel 50 und die Anschlussleitung 63 aus der gleichen Richtungen in die obere Gehäuseschale 30 erfolgen, können das Kabel 50 und die Anschlussleitung 63 zunächst parallel geführt werden und ermöglichen dem Benutzer zudem eine einfache Übersicht über den Steckverbinder 10 und die entsprechenden Zuleitungen. Insbesondere behindert dabei die zusätzliche Anschlussleitung 63 für den Potentialausgleich auch nicht den Zugang zu der unteren Gehäuseschale 40.The contact tongue 66 is preferably arranged on the upper housing shell 30, that the connecting line 63 in the same direction as the cable 50 can be brought to the upper housing shell 30. The contact tongue 66 can alternatively also be arranged within the upper housing shell 30 and in particular on the charging piece 32. The fact that the supply direction for the cable 50 and the connecting line 63 made from the same directions in the upper housing shell 30, the cable 50 and the connecting line 63 can first be performed in parallel and also allow the user a simple overview of the connector 10 and the corresponding supply lines. In particular, the additional connection line 63 for equipotential bonding does not hinder access to the lower housing shell 40.
