Description

Die Erfindung betrifft einen elektrischen Steckverbinder mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to an electrical connector with the features of the preamble of claim 1.

Elektrische Steckverbinder sind bekannt. Sie können ein- oder mehrpolig sein und dienen zum Verbinden ein- oder mehrpoliger elektrischer Kabel durch Ein-oder Zusammenstecken eines Steckverbinders in eine Kupplung oder zweier Steckverbinder. Sofern Steckverbinder ein metallenes Gehäuse oder allgemein ein oder mehrere metallene oder sonstige elektrisch leitfähige Teile außen oder jedenfalls berührbar angeordnet aufweisen, stellt sich das Problem eines Schutzes gegen elektrischen Schlag. Eine Sicherheitsmaßnahme ist eine Schutzerdung, d. h. eine elektrisch leitende Verbindung außenliegender oder jedenfalls berührbarer elektrisch leitender Teile mit einem Schutzleiter.Electrical connectors are known. They can be single or multi-pole and are used to connect single or multi-pole electrical cables by plugging or plugging a connector into a coupling or two connectors. If plug connectors have a metal housing or generally one or more metal or other electrically conductive parts arranged outside or in any case touchable, the problem of protection against electric shock arises. A safety measure is protective grounding, i. H. an electrically conductive connection of external or in any case touchable electrically conductive parts with a protective conductor.

Das Patent DE 39 12 189 C2 offenbart einen elektrischen Steckverbinder in Bauform eines zylindrischen mehrpoligen Rundsteckverbinders mit einem hülsenförmigen metallenen Gehäuse, das eine Schutzerdung ermöglicht. In dem hülsenförmigen metallenen Gehäuse ist ein zylindrischer, elektrisch isolierender Kontakthalter aus Kunststoff angeordnet, in dem achsparallel und damit in einer Steckrichtung des Steckverbinders mehrere elektrische Kontakte gehalten sind, von denen einer als Schutzkontakt dient. Der elektrisch isolierende Kontakthalter ist von einem ringförmigen, an einer Umfangsstelle offenen und in radialer Richtung federnden elektrischen Verbinder umschlossen, der unter elastischer Vorspannung innen am metallenen Gehäuse des Steckverbinders anliegt und dadurch elektrisch leitend mit dem Gehäuse in Kontakt steht. An einer Umfangsstelle ist der elektrisch leitende Verbinder U-förmig nach innen gebogen und liegt dort an dem Schutzkontakt an, wodurch das metallene Gehäuse des Steckverbinders elektrisch leitend mit dem Schutzkontakt verbunden ist.The patent DE 39 12 189 C2 discloses an electrical connector in the form of a cylindrical multi-pole circular connector with a sleeve-shaped metal housing, which enables protective grounding. A cylindrical, electrically insulating contact holder made of plastic is arranged in the sleeve-shaped metal housing, in which a plurality of electrical contacts, one of which serves as a protective contact, are held parallel to the axis and thus in a plug-in direction of the connector. The electrically insulating contact holder is enclosed by an annular electrical connector which is open at a circumferential point and resilient in the radial direction and which rests under elastic prestress on the inside of the metal housing of the connector and is thus in electrically conductive contact with the housing. At a circumferential point, the electrically conductive connector is bent in a U-shape and lies there against the protective contact, as a result of which the metal housing of the connector is electrically conductively connected to the protective contact.

Aufgabe der Erfindung ist, einen elektrischen Steckverbinder der vorstehend erläuterten Art vorzuschlagen, der hinsichtlich eines Zusammenbaus und/oder eines Bauraums verbessert ist.The object of the invention is to propose an electrical connector of the type explained above, which is improved in terms of assembly and / or installation space.

Gelöst wird diese Aufgabe durch einen elektrischen Steckverbinder mit den Merkmalen des Anspruchs 1. Der erfindungsgemäße Steckverbinder weist einen oder mehrere elektrische Kontakte auf, die durch Einstecken oder Zusammenstecken des Steckverbinders in eine Kupplung, einen Gegenstecker oder dgl. jeweils paarweise in elektrisch leitenden Kontakt mit Gegenkontakten der Kupplung, des Gegensteckers oder dgl. gelangen. Der oder die elektrischen Kontakte des erfindungsgemäßen Steckverbinders sind von einem elektrisch isolierenden Kontakthalter gehalten und einer der elektrischen Kontakte ist elektrisch leitend mit einem metallenen Gehäuse oder allgemein einem elektrisch leitenden Teil des Steckverbinders verbunden, das außen oder jedenfalls berührbar am Steckverbinder angeordnet ist. Der elektrisch mit dem Gehäuse oder dem elektrisch leitenden Teil verbundene elektrische Kontakt ist als Schutzkontakt zu einer Schutzerdung des metallenen Gehäuses oder allgemein des elektrisch leitenden Teils des Steckverbinders verwendbar. Bei einem Zusammenbau des erfindungsgemäßen Steckverbinders werden der Kontakthalter und das Gehäuse bzw. das elektrisch leitende Teil in einer Steckrichtung des Steckverbinders relativ zueinander bewegt, wobei ein elektrisch leitende Verbinder gegen das Gehäuse bzw. das elektrisch leitende Teil gelangt und dadurch elektrisch leitend mit dem metallenen Gehäuse oder allgemein dem elektrisch leitenden Teil des Steckverbinders gelangt. Die Steckrichtung des Steckverbinders ist diejenige Richtung, in der der Steckverbinder in mit einer Kupplung, einem Gegenstecker oder dgl. eingesteckt oder zusammengesteckt wird. Zum elektrisch leitenden Verbinden mit dem elektrisch leitenden Verbinder weist das elektrisch leitende Teil eine quer zur Steckrichtung des Steckverbinders verlaufende Kontaktfläche auf. Durch die Relativbewegung des elektrisch leitenden Teils zum Kontakthalter beim Zusammenbau bzw. Zusammensetzen des elektrischen Steckverbinders gelangt die Kontaktfläche des elektrisch leitenden Teils in Anlage und damit in elektrisch leitenden Kontakt mit dem elektrisch leitenden Verbinder, der den einen elektrischen Kontakt des Steckverbinders mit dem elektrisch leitenden Teil des Steckverbinders elektrisch leitend verbindet, um eine Schutzerdung zu ermöglichen. Die Kontaktfläche muss nicht exakt quer zur Steckrichtung des Steckverbinders verlaufen, sondern kann auch in einem spitzen Winkel zur Querrichtung verlaufen. Wesentlich für die Erfindung ist, dass die Kontaktfläche des elektrisch leitenden Teils des Steckverbinders beim Zusammensetzen des Steckverbinders in der Steckrichtung gegen den elektrisch leitenden Verbinder stößt. Die Kontaktfläche des elektrisch leitenden Teils, insbesondere eines metallenen Gehäuses des erfindungsgemäßen Steckverbinders wird vorzugsweise von einer Stirnfläche des elektrisch leitenden Teils gebildet, die beim Zusammensetzen in der Steckrichtung des Steckverbinders gegen den elektrisch leitenden Verbinder stößt.This object is achieved by an electrical plug connector with the features of claim 1. The plug connector according to the invention has one or more electrical contacts which, by inserting or plugging the plug connector into a coupling, a mating plug or the like, each in pairs in electrically conductive contact with mating contacts the coupling, the mating connector or the like. The one or more electrical contacts of the connector according to the invention are held by an electrically insulating contact holder and one of the electrical contacts is electrically conductively connected to a metal housing or generally an electrically conductive part of the connector which is arranged on the outside of the connector or in any case touchable. The electrical contact electrically connected to the housing or the electrically conductive part can be used as a protective contact to a protective grounding of the metal housing or generally of the electrically conductive part of the connector. When the connector according to the invention is assembled, the contact holder and the housing or the electrically conductive part are moved relative to one another in a plug-in direction of the connector, an electrically conductive connector coming against the housing or the electrically conductive part and thereby being electrically conductive with the metal housing or generally the electrically conductive part of the connector. The direction of insertion of the connector is the direction in which the Connector is plugged in or plugged together with a coupling, a mating connector or the like. For the electrically conductive connection to the electrically conductive connector, the electrically conductive part has a contact surface running transversely to the plugging direction of the connector. Due to the relative movement of the electrically conductive part to the contact holder during assembly or assembly of the electrical connector, the contact surface of the electrically conductive part comes into contact and thus comes into electrically conductive contact with the electrically conductive connector, which is the one electrical contact of the connector with the electrically conductive part of the connector connects electrically conductive to enable protective grounding. The contact surface does not have to run exactly transverse to the plugging direction of the connector, but can also run at an acute angle to the transverse direction. It is essential for the invention that the contact surface of the electrically conductive part of the connector abuts the electrically conductive connector in the plugging direction when the connector is assembled. The contact surface of the electrically conductive part, in particular a metal housing of the connector according to the invention, is preferably formed by an end face of the electrically conductive part, which abuts against the electrically conductive connector when it is assembled in the direction of insertion of the connector.

Die Erfindung benötigt für den elektrisch leitenden Verbinder zur Schutzerdung weniger Platz in der Steckrichtung, was ohne Verlängerung des Steckverbinders beispielsweise die Anordnung eines O-Rings und/oder eine Codierung am Kontakthalter ermöglicht. Das Zusammensetzen des Steckverbinders ist dadurch verbessert, dass der Kontakthalter nicht gegen einen ringförmigen elektrisch leitenden Verbinder stößt und anschließend durch den Verbinder gesteckt werden muss, sondern in der Steckrichtung nur in Anlage am elektrisch leitenden Verbinder bewegt wird. Der Steckverbinder lässt sich dadurch gleichmäßig ohne "Hakeln" am elektrisch leitenden Verbinder zusammensetzen.The invention requires less space in the plug-in direction for the electrically conductive connector for protective grounding, which, for example, allows the arrangement of an O-ring and / or coding on the contact holder without extending the plug connector. The assembly of the connector is improved in that the contact holder does not abut an annular, electrically conductive connector and then has to be inserted through the connector, but is only moved in the plugging direction in contact with the electrically conductive connector. The connector can thus be assembled evenly without "hooking" on the electrically conductive connector.

Wie bereits ausgeführt, weist eine Ausführung des erfindungsgemäßen Steckverbinders ein metallenes Gehäuse als elektrisch leitendes Teil auf, das durch den elektrisch leitenden Verbinder elektrisch leitend mit einem elektrischen Kontakt des Steckverbinders verbunden ist.As already stated, an embodiment of the connector according to the invention has a metal housing as an electrically conductive part, which is characterized by the electrically conductive connector is electrically connected to an electrical contact of the connector.

Zu einer mechanischen und elektrisch leitenden Verbindung des elektrisch leitenden Verbinders mit dem elektrischen Kontakt sieht eine Ausgestaltung der Erfindung eine Durchtrittsöffnung des elektrisch leitenden Verbinders vor, durch die der elektrische Kontakt durchgeht. Das ermöglicht sowohl einen einfachen Zusammenbau als auch eine dauerhaft zuverlässige elektrisch leitende Verbindung des elektrischen Kontakts mit dem elektrisch leitenden Verbinder.For a mechanical and electrically conductive connection of the electrically conductive connector to the electrical contact, an embodiment of the invention provides a passage opening of the electrically conductive connector through which the electrical contact passes. This enables both simple assembly and a permanently reliable electrically conductive connection of the electrical contact with the electrically conductive connector.

In bevorzugter Ausgestaltung federt der elektrisch leitende Verbinder in der Steckrichtung des Steckverbinders und liegt mit einer mechanischen Vorspannung in der Steckrichtung an dem elektrisch leitenden Teil an. Dadurch wird eine zuverlässige elektrisch leitende Verbindung des elektrisch leitenden Teils des Steckverbinders mit dem elektrisch leitenden Verbinder und eine Herstellungs- und Zusammenbautoleranz in der Steckrichtung des elektrischen Steckverbinders erreicht, die zugleich die Zusammenbaurichtung ist.In a preferred embodiment, the electrically conductive connector springs in the plug-in direction of the connector and bears against the electrically conductive part with a mechanical preload in the plug-in direction. As a result, a reliable electrically conductive connection of the electrically conductive part of the connector with the electrically conductive connector and a manufacturing and assembly tolerance in the plug-in direction of the electrical connector is achieved, which is also the direction of assembly.

Eine Ausgestaltung der Erfindung sieht vor, dass der Steckverbinder ein Widerlager für den elektrisch leitenden Verbinder aufweist, an dem sich der elektrisch leitende Verbinder in der Steckrichtung, die zugleich die Zusammenbaurichtung ist, abstützt. Das Widerlager kann beispielsweise eine Ringschulter oder ein Flansch am Kontakthalter sein, wobei andere Widerlager nicht ausgeschlossen sind. Das metallene Gehäuse oder allgemein das elektrisch leitende Teil des erfindungsgemäßen Steckverbinders liegt mit Abstand vom Widerlager oder von der oder den Stellen, an denen sich der elektrisch leitende Verbinder am Widerlager abstützt, an dem elektrisch leitenden Verbinder an. Das Widerlager ermöglicht ein Federn des elektrisch leitenden Verbinders in der Steckrichtung des Steckverbinders. Durch die Anlage des elektrisch leitenden Teils des Steckverbinders mit Abstand vom Widerlager und mit Vorspannung in der Steckrichtung am elektrisch leitenden Verbinder verursacht das elektrisch leitende Teil ein Kippmoment am elektrisch leitenden Verbinder, der dadurch mit beispielsweise einer Durchtrittsöffnung auf dem elektrischen Kontakt verkantet, wodurch zuverlässig eine dauerhafte elektrisch leitende Verbindung des elektrisch leitenden Verbinders mit dem elektrischen Kontakt erreicht wird.One embodiment of the invention provides that the plug connector has an abutment for the electrically conductive connector, on which the electrically conductive connector is supported in the direction of insertion, which is also the direction of assembly. The abutment can be, for example, an annular shoulder or a flange on the contact holder, other abutments not being excluded. The metal housing or generally the electrically conductive part of the connector according to the invention bears against the electrically conductive connector at a distance from the abutment or from the point or locations at which the electrically conductive connector is supported on the abutment. The abutment enables the electrically conductive connector to spring in the direction of insertion of the connector. Due to the installation of the electrically conductive part of the connector at a distance from the abutment and with pretension in the plug-in direction on the electrically conductive connector, the electrically conductive part causes a tilting moment on the electrically conductive connector, which thereby jams with, for example, a passage opening on the electrical contact, thereby making it reliable a permanent electrically conductive connection of the electrically conductive connector to the electrical contact is achieved.

Eine Ausgestaltung der Erfindung sieht einen bügelförmigen elektrisch leitenden Verbinder vor, der beispielsweise als Blechstanz- und Biegeteil hergestellt ist und durch seine Bügelform zwei Federschenkel aufweist, die den Kontakthalter seitlich umgreifen und mit einer elastischen Vorspannung in der Steckrichtung des Steckverbinders an dem elektrisch leitenden Teil anliegen. Diese Ausgestaltung der Erfindung ist preisgünstig herstellbar, einfach zusammenbaubar und in der Steckrichtung bauraumsparend.One embodiment of the invention provides a bow-shaped electrically conductive connector, which is manufactured, for example, as a sheet metal stamping and bent part and, due to its bow shape, has two spring legs which grip around the contact holder laterally and bear against the electrically conductive part with an elastic pretension in the direction of insertion of the connector , This embodiment of the invention is inexpensive to manufacture, easy to assemble and space-saving in the direction of insertion.

Der in der Zeichnung dargestellte erfindungsgemäße elektrische Steckverbinder 1 ist im dargestellten und beschriebenen Ausführungsbeispiel ein mehrpoliger Rundstecker, was allerdings nicht zwingend für die Erfindung ist. Er weist einen elektrisch isolierenden Kontakthalter 2 aus Kunststoff auf, der eine zylindrische Grundform aufweist. Der Kontakthalter 2 hält elektrische Kontakte 3 und ist von einem hülsenförmigen metallenen Gehäuse 4 umschlossen, wobei der elektrisch isolierende Kontakthalter 2 die Kontakte 3 jeweils einzeln und im Gehäuse 4 umschließt, so dass die Kontakte 3 elektrisch voneinander und vom Gehäuse 4 isoliert sind. Das Gehäuse 4 kann allgemein auch als elektrisch leitendes Teil 5 des Steckverbinders 1 aufgefasst werden, das außen am Steckverbinder 1 angeordnet und somit berührbar ist.The electrical connector 1 according to the invention shown in the drawing is a multi-pole circular connector in the exemplary embodiment shown and described, although this is not essential for the invention. It has an electrically insulating contact holder 2 made of plastic, which is a cylindrical Has basic shape. The contact holder 2 holds electrical contacts 3 and is enclosed by a sleeve-shaped metal housing 4, the electrically insulating contact holder 2 enclosing the contacts 3 individually and in the housing 4, so that the contacts 3 are electrically insulated from one another and from the housing 4. The housing 4 can generally also be understood as an electrically conductive part 5 of the connector 1, which is arranged on the outside of the connector 1 and can thus be touched.

Im Ausführungsbeispiel ist der Steckverbinder 1 5-polig, er weist fünf elektrische Kontakte 3 auf, die axial gesehen an Ecken eines gedachten gleichseitigen Fünfecks angeordnet sind. Die Anzahl und Anordnung der Kontakte 3 ist nicht wesentlich für die Erfindung. Im Ausführungsbeispiel sind die Kontakte 3 Metallstifte, die achsparallel in Durchgangslöcher im Kontakthalter 2 eingepresst und dadurch vom Kontakthalter 2 gehalten sind. Einer der Kontakte 3 ist über einen elektrisch leitenden Verbinder 6 elektrisch leitend mit dem Gehäuse 4 verbunden. Er wird nachfolgend auch als Schutzkontakt 7 bezeichnet und ermöglicht eine Schutzerdung des Gehäuses 4. Metallstifte sind nicht zwingend für die Erfindung, die Kontakte 3 können beispielsweise auch Messerkontakte oder Buchsen und die Kontakte 3 können verschieden sein.In the exemplary embodiment, the connector 1 is 5-pin, it has five electrical contacts 3, which are arranged axially at the corners of an imaginary equilateral pentagon. The number and arrangement of the contacts 3 is not essential to the invention. In the exemplary embodiment, the contacts 3 are metal pins which are pressed into parallel through-holes in the contact holder 2 and are thus held by the contact holder 2. One of the contacts 3 is electrically conductively connected to the housing 4 via an electrically conductive connector 6. It is also referred to below as protective contact 7 and enables protective grounding of the housing 4. Metal pins are not essential for the invention, the contacts 3 can also be knife contacts or sockets, for example, and the contacts 3 can be different.

Der elektrisch leitende Verbinder 6 ist ein bügelförmiges Blechstanz- und Biegeteil, das durch seine Bügelform zwei Federschenkel 9 (Figur 6) aufweist, die den Kontakthalter 2 auf gegenüberliegenden Seiten seitlich umgreifen. Der elektrisch leitende Verbinder 6 liegt auf einem Flansch 10 des Kontakthalters 2 auf, der ein Widerlager 11 für den elektrisch leitenden Verbinder 6 bildet, das den elektrisch leitenden Verbinder 6 axial abstützt. Axial ist eine Steckrichtung des Steckverbinders 1 beim Einstecken in eine nicht gezeigte Kupplung oder beim Zusammenstecken mit einem nicht gezeigten Gegenstecker. Der das Widerlager 11 bildende Flansch 10 stützt den elektrisch leitenden Verbinder 6 also in der Steckrichtung des Steckverbinders 1 ab.The electrically conductive connector 6 is a bow-shaped sheet metal stamping and bending part, which has two spring legs 9 ( Figure 6 ) which laterally engage around the contact holder 2 on opposite sides. The electrically conductive connector 6 lies on a flange 10 of the contact holder 2, which forms an abutment 11 for the electrically conductive connector 6, which axially supports the electrically conductive connector 6. Axial is a plug-in direction of the connector 1 when plugged into a coupling, not shown, or when plugging together with a mating plug, not shown. The flange 10 forming the abutment 11 thus supports the electrically conductive connector 6 in the plug-in direction of the connector 1.

Die den Kontakthalter 2 seitlich umgreifenden Federschenkel 9 des elektrisch leitenden Verbinders 6 sind mit einer Wölbung gebogen, so dass sie in unverformtem Zustand (Figur 7) schräg in einem spitzen Winkel, der sich über eine Länge der Federschenkel 9 ändert, vom Flansch 10 weg in Richtung des Gehäuses 4 abstehen. Wird das Gehäuse 4 beim Zusammenbau auf den Kontakthalter 2 aufgesetzt, gelangt ein Stirnrand 12 des Gehäuses 4 in Anlage an freie Enden der Federschenkel 9 des elektrisch leitenden Verbinders 6 und beaufschlagt die Federschenkel 9 elastisch in bzw. entgegen der Steckrichtung des Steckverbinders 1 zu dem das Widerlager 11 für den elektrisch leitenden Verbinder 6 bildenden Flansch 10 des Kontakthalters 2. Auf diese Weise ist das Gehäuse 4 des Steckverbinders 1 elektrisch leitend mit dem elektrisch leitenden Verbinder 6 verbunden. Der Stirnrand 12 des Gehäuses 4 bildet eine Kontaktfläche 19, die an den Federschenkeln 9 des elektrisch leitenden Verbinders 6 anliegt, so dass das Gehäuse 4 elektrisch leitend mit dem elektrisch leitenden Verbinder 6 verbunden ist.The spring legs 9 of the electrically conductive connector 6 which laterally encompass the contact holder 2 are curved with a curvature, so that they are undeformed Status ( Figure 7 ) protrude at an acute angle, which changes over a length of the spring legs 9, away from the flange 10 in the direction of the housing 4. If the housing 4 is placed on the contact holder 2 during assembly, an end edge 12 of the housing 4 comes into contact with free ends of the spring legs 9 of the electrically conductive connector 6 and acts elastically on the spring legs 9 in or against the plug-in direction of the connector 1 to which the Abutment 11 for the electrically conductive connector 6 forming flange 10 of the contact holder 2. In this way, the housing 4 of the connector 1 is electrically conductively connected to the electrically conductive connector 6. The front edge 12 of the housing 4 forms a contact surface 19, which bears against the spring legs 9 of the electrically conductive connector 6, so that the housing 4 is electrically conductively connected to the electrically conductive connector 6.

Weil die Federschenkel 9 in achsparalleler Richtung und damit in der Zusammenbau- und Steckrichtung des Steckverbinders 1 mit verhältnismäßig langem Federweg federn, ist ein großer Fertigungs- und Zusammenbautoleranzausgleich gewährleistet und die elektrisch leitende Verbindung des Gehäuses 4 mit dem elektrisch leitenden Verbinder 6 zuverlässig und dauerhaft gewährleistet.Because the spring legs 9 spring in the axially parallel direction and thus in the assembly and plug-in direction of the connector 1 with a relatively long spring travel, a large manufacturing and assembly tolerance compensation is guaranteed and the electrically conductive connection of the housing 4 with the electrically conductive connector 6 is reliably and permanently ensured ,

Mit Ausnahme des elektrisch leitenden Verbinders 6, der in noch zu erläuternder Weise seitlich in bzw. auf den Kontakthalter 2 gesteckt wird, erfolgt der Zusammenbau des Steckverbinders 1, nämlich das Einpressen der Kontakte 3 in den Kontakthalter 2 und das Aufsetzen des Gehäuses 4 auf den Kontakthalter 2, in achsparalleler bzw. axialer Richtung, die zugleich die Steckrichtung des Steckverbinders 1 beim Einstecken in eine Kupplung oder beim Zusammenstecken mit einem Gegenstecker ist. Der Zusammenbau ist eine Relativbewegung des Kontakthalters 2, der Kontakte 3 und des Gehäuses 4 zueinander in achsparalleler bzw. axialer Richtung, die zugleich die Steckrichtung des Steckverbinders 1 ist. Der Zusammenbau des Steckverbinders 1 kann auch als Zusammensetzen seiner Teile aufgefasst werden.With the exception of the electrically conductive connector 6, which is laterally inserted in or onto the contact holder 2, the connector 1 is assembled, namely the pressing of the contacts 3 into the contact holder 2 and the placement of the housing 4 on the Contact holder 2, in the axis-parallel or axial direction, which is also the plug-in direction of the connector 1 when plugged into a coupling or when plugged together with a mating connector. The assembly is a relative movement of the contact holder 2, the contacts 3 and the housing 4 to one another in the axis-parallel or axial direction, which is also the plug-in direction of the connector 1. The assembly of the connector 1 can also be understood as the assembly of its parts.

Der elektrisch leitende Verbinder 6 weist in einer Mitte eines seine Federschenkel 9 verbindenden Jochs 20 eine Lasche 13 auf, die nach einem Stanzen des Verbinders 6 nach außen absteht und U-förmig nach innen umgebogen ist. Zum Zusammenbau wird der elektrisch leitende Verbinder 6 - bevor die Kontakte 3 oder jedenfalls bevor der Schutzkontakt 7 in den Kontakthalter 2 eingepresst wird - seitlich auf den Kontakthalter 2 gesetzt, so dass seine beiden Federschenkel 9 den Kontakthalter 2 auf einander gegenüberliegenden Seiten seitlich umgreifen. Dabei gelangt die Lasche 13 des elektrisch leitenden Verbinders 6 auf eine dem Gehäuse 4 abgewandte Rückseite des Flanschs 10 des Kontakthalters 2, wogegen sich das Joch 20 und die Federschenkel 9 auf einer dem Gehäuse 4 zugewandten Vorderseite des Flanschs 10 befinden. Der Flansch 10 Kontakthalters 2 befindet sich zwischen den Federschenkeln 9 einerseits und der Lasche 13 und dem Joch 20 andererseits, so dass der elektrisch leitende Verbinder 6 mechanisch am Kontakthalter 2 gehalten ist.In a center of a yoke 20 connecting its spring legs 9, the electrically conductive connector 6 has a tab 13 which, after the connector 6 has been punched, protrudes outwards and is bent inward in a U-shape. For assembly, the electrically conductive connector 6 is placed laterally on the contact holder 2 before the contacts 3 or in any case before the protective contact 7 is pressed into the contact holder 2, so that its two spring legs 9 laterally engage around the contact holder 2 on opposite sides. The tab 13 of the electrically conductive connector 6 reaches a rear side of the flange 10 of the contact holder 2 facing away from the housing 4, whereas the yoke 20 and the spring legs 9 are located on a front side of the flange 10 facing the housing 4. The flange 10 contact holder 2 is located between the spring legs 9 on the one hand and the tab 13 and the yoke 20 on the other hand, so that the electrically conductive connector 6 is mechanically held on the contact holder 2.

In der Lasche 13 weist der elektrisch leitende Verbinder 6 eine Durchtrittsöffnung 15 für den Schutzkontakt 7 auf, die mit einer halbkreisförmigen Anlage 21 für den Schutzkontakt 7 in der Mitte des Jochs 20 des Verbinders 6 fluchtet. Der Schutzkontakt 7 wird durch die Durchtrittsöffnung 15 des elektrisch leitenden Verbinders 6 in das für ihn vorgesehene achsparallele Durchgangsloch des Kontakthalters 2 eingepresst und liegt außer an der Durchtrittsöffnung 15 an der Anlage 21 an. Dadurch ist der Schutzkontakt 7 elektrisch leitend mit dem elektrisch leitenden Verbinder 6 verbunden und über den elektrisch leitenden Verbinder 6 ist das Gehäuse 4 elektrisch leitend mit dem Schutzkontakt 7 des Steckverbinders 1 verbunden, was eine Schutzerdung des Gehäuses 4 möglich macht.In the tab 13, the electrically conductive connector 6 has a passage opening 15 for the protective contact 7, which is aligned with a semicircular contact 21 for the protective contact 7 in the middle of the yoke 20 of the connector 6. The protective contact 7 is pressed through the passage opening 15 of the electrically conductive connector 6 into the axially parallel through hole provided for it in the contact holder 2 and is in contact with the system 21 in addition to the passage opening 15. As a result, the protective contact 7 is electrically conductively connected to the electrically conductive connector 6 and the housing 4 is electrically conductively connected to the protective contact 7 of the plug connector 1 via the electrically conductive connector 6, which makes protective grounding of the housing 4 possible.

Für eine zuverlässige und elektrisch gut leitende Verbindung des elektrisch leitenden Verbinders 6 mit dem Schutzkontakt 7 weist der Schutzkontakt 7 einen Flansch 16 auf, der an der Lasche 13 des elektrisch leitenden Verbinders 6 anliegt. Eine zusätzliche Maßnahme für eine gute elektrisch leitende Verbindung des elektrisch leitenden Verbinders 6 mit dem Schutzkontakt 7 ist ein Untermaß der Durchtrittsöffnung 15 des elektrisch leitenden Verbinders 6 in Bezug auf den Schutzkontakt 7 und/oder ein Versatz der Anlage 21 zu der Durchtrittsöffnung 15 in Richtung des Schutzkontakts 7 und/oder zu dem achsparallelen Durchgangsloch im Kontakthalter 2, in das der Schutzkontakt 7 eingepresst ist. Diese Maßnahmen sorgen für ein Anliegen des Schutzkontakts 7 an der Anlage 21 und an einer gegenüberliegenden Seite der Durchtrittsöffnung 15 des elektrisch leitenden Verbinders 6 mit einer Kontaktkraft. Die elastische Verformung der Federschenkel 9 des elektrisch leitenden Verbinders 6 durch das in der Steckrichtung des Steckverbinders 1 gegen sie drückende Gehäuse 4 beansprucht den elektrisch leitenden Verbinder 6 auf Biegung, was ebenfalls eine Kontaktkraft eines Randes der Durchtrittsöffnung 15 des elektrisch leitenden Verbinders 6 in der Mitte zwischen seinen beiden Federschenkeln 9 gegen den Schutzkontakt 7 verursacht. Des Weiteren liegt das Gehäuse 4 an den freien Enden der Federschenkel 9 und damit mit Abstand von der Stelle, an der sich der elektrisch leitende Verbinder 6 an dem das Widerlager 11 bildenden Flansch 10 abstützt, an. Das bewirkt ein Kippmoment auf den elektrisch leitenden Verbinder 6, das ebenfalls eine Kontaktkraft der Anlage 21 und des Randes der Durchtrittsöffnung 15 des elektrisch leitenden Verbinders 6 gegen den Schutzkontakt 7 bewirkt. Für eine elektrisch gut leitende Verbindung des elektrisch leitenden Verbinders 6 mit dem Schutzkontakt 7 genügt grundsätzlich eine oder auch eine beliebige Kombination der vorgenannten Maßnahmen, eine Verwirklichung aller vorgenannten Maßnahmen ist nicht notwendig.For a reliable and good electrical connection between the electrically conductive connector 6 and the protective contact 7, the protective contact 7 has a flange 16 which bears on the tab 13 of the electrically conductive connector 6. An additional measure for a good electrically conductive connection of the electrically conductive connector 6 to the protective contact 7 is an undersize of the passage opening 15 of the electrically conductive connector 6 with respect to the Protective contact 7 and / or an offset of the system 21 to the passage opening 15 in the direction of the protective contact 7 and / or to the through hole in the contact holder 2 which is parallel to the axis and into which the protective contact 7 is pressed. These measures ensure that the protective contact 7 bears against the system 21 and on an opposite side of the passage opening 15 of the electrically conductive connector 6 with a contact force. The elastic deformation of the spring legs 9 of the electrically conductive connector 6 by the housing 4 pressing against them in the plug-in direction of the connector 1 stresses the electrically conductive connector 6 to bend, which likewise results in a contact force of an edge of the passage opening 15 of the electrically conductive connector 6 in the middle caused between its two spring legs 9 against the protective contact 7. Furthermore, the housing 4 lies against the free ends of the spring legs 9 and thus at a distance from the point at which the electrically conductive connector 6 is supported on the flange 10 forming the abutment 11. This causes a tilting moment on the electrically conductive connector 6, which also causes a contact force of the system 21 and the edge of the passage opening 15 of the electrically conductive connector 6 against the protective contact 7. In principle, one or any combination of the aforementioned measures is sufficient for an electrically well-conductive connection of the electrically conductive connector 6 to the protective contact 7; it is not necessary to implement all of the aforementioned measures.

In axialer Richtung, also in der Steckrichtung des Steckverbinders 1, benötigt der elektrisch leitende Verbinder 6 nur ungefähr seine Dicke oder ungefähr das Doppelte bis ungefähr das Dreifache seiner Dicke als Bauraum. Das ermöglicht die Anordnung eines O-Rings oder sonstigen Dichtrings (nicht dargestellt) in einer umlaufenden Nut des Kontakthalters 2 ohne eine Baulänge des Steckverbinders 1 in axialer und Steckrichtung zu vergrößern. Ebenfalls ist ein Schriftfeld 18 für eine Beschriftung, Codierung oder dgl. auf einer dem Gehäuse 4 zugewandten Seite des Flansches 10 des Kontakthalters 2 möglich, ohne die Baulänge des Steckverbinders 1 zu vergrößern.In the axial direction, that is to say in the plug-in direction of the connector 1, the electrically conductive connector 6 requires only approximately its thickness or approximately twice to approximately three times its thickness as installation space. This enables the arrangement of an O-ring or other sealing ring (not shown) in a circumferential groove of the contact holder 2 without increasing the overall length of the connector 1 in the axial and plug-in directions. A writing field 18 for labeling, coding or the like is also possible on a side of the flange 10 of the contact holder 2 facing the housing 4 without increasing the overall length of the connector 1.
