Description

Die vorliegende Erfindung betrifft einen Stecker, insbesondere einen Stecker für die elektrische Anbindung eines Verbrauchers in einem Kraftfahrzeug. Insbesondere betrifft die vorliegende Erfindung einen Stecker, der geeignet ist, mit hoher Spannung betriebene Geräte in einem Kraftfahrzeug elektrisch an eine Spannungsversorgung anzuschließen. Solche Hochvolt-Verbraucher kommen zunehmend insbesondere im Rahmen der Herstellung von Elektrofahrzeugen in Betracht.The present invention relates to a plug, in particular a plug for the electrical connection of a consumer in a motor vehicle. In particular, the present invention relates to a plug which is adapted to electrically connect high voltage powered devices in a motor vehicle to a power supply. Such high-voltage consumers are increasingly being considered particularly in the production of electric vehicles.

Dabei will die vorliegende Erfindung besonders bevorzugt einen Stecker angeben, mit dem elektrische Heizvorrichtungen in einem Kraftfahrzeug an ein Bordnetz angeschlossen werden können.In this case, the present invention particularly preferably specifies a plug with which electrical heating devices in a motor vehicle can be connected to a vehicle electrical system.

Zur Lösung dieses Problems wird mit der vorliegenden Erfindung ein Stecker mit den Merkmalen von Anspruch 1 vorgeschlagen. Dieser Stecker hat in an sich bekannter Weise ein Steckergehäuse mit einer Kabeldurchführung. Die Kabeldurchführung ist eine zum Innern des Steckers führende Öffnung, durch welches das anzubindende Kabel üblicherweise unter Verbleib des Kabelmantels in das Steckergehäuse hineingeschoben werden kann. Des Weiteren hat das Steckergehäuse eine Öffnung, die einem elektrischen Kontakt zugeordnet ist. Dabei kann es sich um eine Öffnung handeln, die von dem besagten elektrischen Kontakt überragt ist. Eine solche Ausgestaltung wird üblicherweise bei einem männlichen Stecker zur Anwendung kommen. Ebenso gut ist denkbar, dass die besagte Öffnung zu einem im Wesentlichen in dem Steckergehäuse aufgenommenen elektrischen Steckkontakt führt, d.h. der Stecker als weibliches Element einer Steckerverbindung ausgeformt ist.To solve this problem, a plug with the features of claim 1 is proposed by the present invention. This plug has a plug housing with a cable bushing in a conventional manner. The cable gland is an opening leading to the interior of the plug, through which the cable to be connected can usually be pushed into the connector housing while retaining the cable sheath. Furthermore, the plug housing has an opening which is associated with an electrical contact. This may be an opening that is surmounted by said electrical contact. Such a configuration will usually be used in a male connector. It is equally conceivable that the said opening leads to an electrical plug contact received essentially in the plug housing, i. the plug is formed as a female element of a plug connection.

Die vorliegende Erfindung will insbesondere einen Stecker angeben, der in verbesserter Weise abgeschirmt und mit dieser Abschirmung an ein Gehäuse eines Verbrauchers leitend angeschlossen werden kann, um eine vollständige Abschirmung zwischen dem Gehäuse des Verbrauchers und der Abschirmung des Kabels zu erreichen. Im Hinblick darauf hat der erfindungsgemäße Stecker eine außen an dem Steckergehäuse freiliegende Schirmanbindung. Diese Schirmanbindung ist leitend mit einer Abschirmung des Kabels verbunden, vorzugsweise in einer nachstehend noch näher zu erläuternden Art. Zur Schirmanbindung ist jedenfalls das Steckergehäuse zumindest zweiteilig ausgebildet mit einem die Kabeldurchführung ausbildenden Gehäusebasisteil und einem wenigstens eine Öffnung aufweisenden Gehäusekopfteil. Diese beiden Teile sind miteinander verbunden, und zwar unter Zwischenlagerung der besagten Schirmanbindung, so dass diese von der Außenseite des Gehäuses zwischen den beiden Gehäuseteilen nach innen geführt und dort mit der Abschirmung des Kabels kontaktiert werden kann.In particular, the present invention seeks to provide a plug that can be shielded in an improved manner and conductively connected to a housing of a consumer with this shield to achieve complete shielding between the housing of the consumer and the shielding of the cable. In view of this, the plug according to the invention has an outside of the connector housing exposed shield connection. This shield connection is conductively connected to a shield of the cable, preferably in a manner to be explained in more detail below. For shield connection, in any case, the connector housing is formed at least in two parts a housing base part forming the cable bushing and a housing head part having at least one opening. These two parts are connected to each other, with intermediate storage of said shield connection, so that it can be guided from the outside of the housing between the two housing parts inwards and contacted there with the shield of the cable.

Vorzugsweise umfasst die Schirmanbindung mehrere auf dem Umfang des Steckergehäuses verteilt angeordnete Abschirmkontakte, die an dem freien Ende von beweglich in dem Steckergehäuse gehaltenen Federarmen der Schirmanbindung ausgebildet sind. Wenngleich auch andere Ausgestaltungen, beispielsweise mit einer rechtwinkligen Ausrichtung des zugeführten Kabels relativ zu der Erstreckungsrichtung der Steckkontakte denkbar sind, wird mit der vorliegenden Erfindung im Besonderen eine Ausgestaltung des Steckers bevorzugt, bei welcher das zugeführte Kabel koaxial zu der Erstreckungsrichtung der Steckkontakte liegt. Bei dieser Ausgestaltung erstrecken sich die Federarme zumindest überwiegend in Längsrichtung des zugeführten Kabels, so dass die federnde Ausgleichsbewegung zu einer radialen Bewegung der Abschirmkontakte führt. Ein Gehäuse eines Verbrauchers hat hierzu korrespondierend eine üblicherweise zylindrisch ausgebildete Aufnahme, in welche die Abschirmkontakte eingeschoben werden. Diese können hierfür an ihrem in Einführrichtung vorderen Ende leicht abgeschrägt ausgebildet sein, um ein Verdrängen der Abschirmkontakte radial nach innen zu begünstigen. Mit der elastischen Rückstellung legen sich die Steckkontakte schließlich an die Innenumfangsfläche der Aufnahme an.Preferably, the shield connection comprises a plurality of shield contacts arranged distributed on the circumference of the plug housing and formed on the free end of spring arms of the shield connection movably held in the plug housing. Although other embodiments, for example, with a rectangular orientation of the supplied cable relative to the extension direction of the plug contacts are conceivable, with the present invention in particular an embodiment of the plug is preferred in which the supplied cable is coaxial with the direction of extension of the plug contacts. In this embodiment, the spring arms extend at least predominantly in the longitudinal direction of the supplied cable, so that the resilient compensating movement leads to a radial movement of the Abschirmkontakte. A housing of a consumer has for this purpose a correspondingly cylindrically shaped receptacle into which the shield contacts are inserted. For this purpose, they can be slightly bevelled at their front end in the insertion direction, in order to promote displacement of the shielding contacts radially inwards. With the elastic return, the plug contacts finally put on the inner peripheral surface of the recording.

Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung sind das Gehäusebasisteil und das Gehäusekopfteil sich in Kabelerstreckungsrichtung überdeckend ausgebildet. Dies erfolgt üblicherweise dadurch, dass das Gehäusebasisteil mit einem Glockenende ausgeformt wird, in welches ein Spitzende des Gehäusekopfteils hineinragt, vorzugsweise unter Ausbildung eines Ringspaltes, der üblicherweise zylinderförmig ausgebildet ist und in dem die Federarme radial beweglich gehalten sind, derart, dass der notwendige Federweg zur elastischen Anlage an die gehäuseseitige Aufnahme durch freies Verschwenken den Federarme in den Ringspalt erfolgen kann.According to a preferred embodiment of the present invention, the housing base part and the housing head part are formed overlapping in the cable extension direction. This is usually done in that the housing base part is formed with a bell end, in which a spigot end of the housing head part protrudes, preferably forming an annular gap, which is usually cylindrical and in which the spring arms are held radially movable, such that the necessary spring travel to elastic contact with the housing-side recording by free pivoting the spring arms can be done in the annular gap.

Die Kontaktierung zwischen der Schirmanbindung und der Kabelabschirmung, d.h. einem üblicherweise vom Kabelmantel umgebenen leitenden Gewebe kann auf verschiedene Weisen erfolgen, so beispielsweise über eine Klemmhülsenanordnung, in welche die Kabelabschirmung eingebracht und unter Klemmen elektrisch mit der Schirmanbindung verbunden wird. Allerdings wird mit der vorliegenden Erfindung eine Ausgestaltung bevorzugt, die bei angemessener Vorbereitung des Kabels zwangsläufig zu einer Kontaktierung zwischen den Abschirmkontakten der Kabelabschirmung führt. Diese Verbindung erfolgt vorzugsweise zwangsläufig beim Einbringen der Abschirmung in die Schirmanbindung, wobei diese vorzugsweise so ausgebildet ist, dass sich hierbei auch eine Zugentlastung des Kabels ergibt. Zugkräfte werden danach direkt über die Abschirmung in das Steckergehäuse eingeleitet.The contacting between the shield connection and the cable shield, ie a conductive fabric usually surrounded by the cable sheath can be done in various ways, such as a ferrule assembly, in which the cable shield is inserted and electrically connected under terminals with the shield connection. However, with the present invention, an embodiment is preferred, which inevitably leads to a contact between the Abschirmkontakten the cable shield with appropriate preparation of the cable. This connection is preferably carried out inevitably upon insertion of the shield in the shield connection, which is preferably designed so that in this case also results in a strain relief of the cable. Tensile forces are then introduced directly through the shield in the connector housing.

Mit Blick auf eine möglichst einfache elektrische Kontaktierung zwischen der Kabelabschirmung und der Schirmanbindung umfasst diese vorzugsweise eine Ringfläche, deren Bohrung durch Kontaktstege überragt wird. Diese Kontaktstege sind derart angepasst, dass eine von dem Kabelmantel befreite und stirnseitig das Ende des Kabelmantels überragende Abschirmung von den Kontaktstegen radial nach innen gedrückt und gegen die freigelegten elektrischen Adern bzw. einen Innenmantel des Kabels angedrückt wird. Hierdurch ergibt sich eine elektrische Kontaktierung zwischen der Kabelabschirmung und der Schirmanbindung. Die Kontaktstege sind üblicherweise schräg nach innen geneigt, so dass diese eine sich in Einführrichtung verjüngende trichterförmige Ausgestaltung ausformen, die das Einführen des den freigelegten Kabelmantel überragenden Teils des zugeführten Kabels erleichtern. Dabei ist regelmäßig darauf zu achten, dass die Kontaktstege nicht scharfkantig gegen die Schirmanbindung drücken, was üblicherweise dadurch verwirklicht wird, dass die Kontaktstege eine ballige und mit der Kabelabschirmung zusammenwirkenden Oberfläche aufweisen.With a view to the simplest possible electrical contact between the cable shield and the shield connection, this preferably comprises an annular surface whose bore is surmounted by contact webs. These contact webs are adapted such that a shielded from the cable sheath and frontally beyond the end of the cable sheath shield pressed by the contact webs radially inwardly and is pressed against the exposed electrical wires or an inner sheath of the cable. This results in an electrical contact between the cable shield and the shield connection. The contact webs are usually inclined obliquely inwards, so that they form a funnel-shaped configuration tapering in the insertion direction, which facilitate the insertion of the part of the supplied cable projecting beyond the uncovered cable jacket. It must be ensured on a regular basis that the contact webs do not press sharp edges against the shield connection, which is usually realized by the fact that the contact webs have a crowned and cooperating with the cable shielding surface.

Gemäß einer bevorzugten Weiterbildung der vorliegenden Erfindung weist die besagte Ringfläche wenigstens eine Bohrung auf, die von einem Zapfen durchragt ist, der von einer Stirnseite des Gehäusekopfteiles abragt. Der in der Bohrung befindliche Zapfen bewirkt eine verdrehfeste Sicherung der Abschirmanbindung an dem Gehäusekopfteil und erlaubt ferner das Vormontieren der Schirmanbindung an dem Gehäusekopfteil.According to a preferred embodiment of the present invention, the said annular surface has at least one bore, which is penetrated by a pin which protrudes from an end face of the housing head part. The pin located in the bore causes a rotationally secure securing the Abschirmanbindung on the housing head part and also allows the pre-mounting of the shield connection to the housing head part.

Das Gehäusebasisteil bildet vorzugsweise zu jedem Zapfen eine Zapfenaufnahme aus, in welcher der Zapfen zur verdrehsicheren Halterung des Gehäusekopfteils zusammen mit der Schirmanbindung aufgenommen ist. Eine Verdrehsicherung in diesem Sinne ist aber auch dann gegeben, wenn im montierten Zustand eine gewisse Verdrehbewegung zwischen dem Gehäusebasisteil und dem Gehäusekopfteil möglich ist.The housing base part preferably forms a pin receptacle for each pin, in which the pin is accommodated for a rotationally secure mounting of the housing head part together with the shield connection. A rotation in this sense, however, is also given when a certain rotational movement between the housing base part and the housing head part is possible in the mounted state.

Gemäß einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung hat der Zapfen einen verdickten Zapfenkopf, dem gehäusebasisseitig ein Anschlag zugeordnet ist. Vermöge diese Ausgestaltung sind Gehäusebasisteil und Gehäusekopfteil auch in Längsrichtung unverlierbar miteinander verbunden. Das Gehäusekopfteil kann jedenfalls nicht in Längsrichtung der Zapfen aus dem Gehäusebasisteil herausgezogen werden.According to a further preferred embodiment of the present invention, the pin has a thickened pin head, the housing base side is associated with a stop. By virtue of this configuration, the housing base part and the housing head part are also captively connected to each other in the longitudinal direction. In any case, the housing head part can not be pulled out of the housing base part in the longitudinal direction of the pins.

Gemäß einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung hat die Gehäusebasis eine Dichtlippe zur dichtenden Anlage an ein den Stecker aufnehmendes Gehäuse. Diese Dichtlippe ist aus einer Komponente gebildet, die eine geringere Härte als das das Gehäusebasisteil ausbildende Material hat. Es wird davon ausgegangen, dass das Steckergehäuse und die unmittelbar an dem Steckergehäuse ausgeformten Funktionsflächen üblicherweise aus Kunststoff ausgebildet sind und dass lediglich der bzw. die Steckkontakte aus einem elektrisch leitenden Material ausgeformt sind.According to a further preferred embodiment of the present invention, the housing base has a sealing lip for sealing engagement with a housing receiving the plug. This sealing lip is formed from a component which has a lower hardness than the material forming the housing base part. It is assumed that the plug housing and the functional surfaces formed directly on the plug housing are usually made of plastic, and that only the plug contact or contacts are formed from an electrically conductive material.

Nach einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung weist die Kabeldurchführung wenigstens eine an den Kabelmantel anlegbare Kabeldichtlippe auf. Auch diese Dichtlippe hat eine geringere Härte als das das Gehäusebasisteil ausbildende Material. Vorzugsweise sind die Dichtlippe und die wenigstens eine Kabeldichtlippe aus identischem Material, beispielsweise einem thermoplastischen Elastomer gebildet. Dabei wird vorzugsweise davon ausgegangen, dass die besagten Dichtelemente durch Umspritzen eines Grundkörpers eines Gehäuseschalenelementes des Gehäusebasisteils hergestellt sind, wobei mehrere Gehäuseschalenelemente das Gehäusebasisteil ausformen. Dieses Umspritzen erfolgt üblicherweise über einen einzigen Anspritzpunkt, so dass über diesen einzigen Anspritzpunkt sowohl an dem in Einführrichtung vorderen Ende des Gehäusebasisteils die Dichtlippe als auch am hinteren Ende im Bereich der Kabeldurchführung die wenigstens eine Kabeldichtlippe ausgebildet wird.According to a further preferred embodiment of the present invention, the cable gland on at least one can be applied to the cable sheath cable sealing lip. Also, this sealing lip has a lower hardness than the housing base forming material. Preferably, the sealing lip and the at least one cable sealing lip are formed of identical material, for example a thermoplastic elastomer. It is preferably assumed that the said sealing elements are produced by molding a base body of a housing shell element of the housing base part, wherein a plurality of housing shell elements form the housing base part. This encapsulation usually takes place via a single injection point, so that the sealing lip at the front end of the housing base part in the insertion direction and the at least one cable sealing lip at the rear end are formed via this single injection point.

Im Hinblick darauf ist es zu bevorzugen, das Gehäusebasisteil aus wenigstens zwei, vorzugsweise identisch ausgebildeten Gehäuseschalenelementen auszubilden, die unter Einschluss einer randseitig an den Gehäuseschalenelementen ausgebildeten Gehäuseabdichtlippen gefügt sind. Im Falle von zwei Gehäuseschalenelementen sind diese als Halbschalen ausgebildet und haben an ihren aneinanderliegende Randseiten eine die Abdichtung begünstigende Kontur mit einer vorspringenden Dichtlippe, die vorzugsweise in einer Dichtnut an dem anderen Gehäuseschalenelement im Eingriff ist, so dass die gefügten Gehäuseschalenelemente ein in Umfangsrichtung abgedichtetes Gehäusebasisteil ausformen.In view of this, it is preferable to form the housing base part from at least two, preferably identically designed housing shell elements, which are joined with the inclusion of a housing sealing lips formed on the edge of the housing shell elements. In the case of two housing shell elements, these are designed as half shells and have at their abutting edge sides a contour favoring the seal with a projecting sealing lip, which is preferably in a sealing groove on the other housing shell element in engagement, so that the joined housing shell elements form a circumferentially sealed housing base part.

Gemäß einer weiteren bevorzugten Ausgestaltung der vorliegenden Erfindung ist das Gehäusekopfteil aus wenigstens zwei Gehäusekopfsegmenten ausgebildet, die über ein Filmscharnier miteinander verbunden sind. Mit Blick auf eine leichte Verkabelung des Steckers hat wenigstens eines der Gehäusekopfelemente eine randseitig offene und zu einer Steckkontaktaufnahme führende Einführnut. Diese Nut erstreckt sich vorzugsweise in Umfangsrichtung des Gehäusekopfteils, üblicherweise in Umfangsrichtung und ist dementsprechend zu einer Randfläche, die sich im Wesentlichen parallel zu der Erstreckungsrichtung des Steckkontaktes erstreckt, offen. Eine elektrische und mit einem Steckkontaktelement verbundene Ader eines angeschlossenen Kabels kann dementsprechend seitlich in die Nut eingeführt werden so, dass der entsprechende Steckkontakt in der Steckkontaktaufnahme angeordnet wird. Diese Lage des besagten Steckkontaktes wird vorzugsweise dadurch endgültig gesichert, dass die Einführnut im gefügten Zustand innerhalb des Gehäusebasisteils befindlich ist, wobei das Zusammenwirken von Gehäusebasisteil und Gehäusekopfteil ein Herausdrängen der Kabelader aus der Nut verhindert.According to a further preferred embodiment of the present invention, the housing head part is formed from at least two housing head segments, which are connected to each other via a film hinge. With a view to easy wiring of the plug, at least one of the housing head elements has an insertion groove open at the edge and leading to a plug contact receptacle. This groove preferably extends in the circumferential direction of the housing head part, usually in the circumferential direction and is accordingly open to an edge surface which extends substantially parallel to the extension direction of the plug contact. An electrical wire connected to a plug contact element of a connected cable can accordingly be inserted laterally into the groove so that the corresponding plug contact is arranged in the plug contact receptacle. This position of said plug contact is preferably finally secured by the fact that the insertion is located in the assembled state within the housing base part, wherein the interaction of the housing base part and the housing head part prevents the cable core from extruding out of the groove.

Further details and advantages of the present invention will become apparent from the following description of an embodiment in conjunction with the drawings. In this show:

Das in den Figuren 1 bis 4 gezeigte Ausführungsbeispiels eines Steckers umfasst ein zweiteiliges Steckergehäuses 2 mit einem Gehäusebasisteil 4 und einem Gehäusekopfteil 6, die im gefügten Zustand teilweise ineinander gesteckt sind. Hierzu hat das Gehäusebasisteil 4 ein Glockenende 8, in welches ein Spitzende 10 des Gehäusekopfteils 6 passt.That in the FIGS. 1 to 4 shown embodiment of a connector comprises a two-part connector housing 2 with a housing base part 4 and a housing head part 6, which are partially inserted in the joined state. For this purpose, the housing base part 4 has a bell end 8 into which a spigot end 10 of the housing head part 6 fits.

Das Glockenende 8 und das Spitzende 10 sind vorliegend rotationssymmetrisch und mit zylindrischer Umfangsfläche ausgebildet. Im gefügten Zustand (vgl. Figur 3) lassen das Glockenende 8 und das Spitzende 10 zwischen sich einen Ringspalt 12 frei. In diesem Ringspalt 12 erstrecken sich Federarme 14 einer mit Bezugszeichen 16 gekennzeichneten Schirmanbindung. Die Federarme 14 gehen von einem Ringsegment 18 ab, dessen Bohrung 20 durch eine Vielzahl von Kontaktstegen 22 radial nach innen überragt sind. Die Kontaktstege 22 sind in axialer Richtung zu dem in Einführrichtung vorderen Ende des Gehäusebasisteiles 4 umbogen und bilden dementsprechend eine Trichteröffnung 24 aus.The bell end 8 and the spigot 10 are present rotationally symmetrical and formed with a cylindrical peripheral surface. In the joined state (cf. FIG. 3 ), the bell end 8 and the spigot end 10 between an annular gap 12 free. In this annular gap 12 spring arms 14 extend a marked with reference numeral 16 shield connection. The spring arms 14 are based on a ring segment 18, the bore 20 are projected by a plurality of contact webs 22 radially inwardly. The contact webs 22 are arched in the axial direction to the front end of the housing base part 4 in the insertion direction and accordingly form a funnel opening 24.

Die Kontaktstege 22 sind in Umfangsrichtung voneinander durch durch Stanzen gebildete Schlitze getrennt. In gleicher Weise voneinander getrennt sind die Federarme 14. Das Ringsegment 18 bildet dabei eine Basis der Schirmanbindung 16 aus, um welche sowohl die Federarme 14 als auch die Kontaktstege 22 verschwenkbar sind. Der Außendurchmesser des Ringsegmentes 18 und der hiervon im Wesentlichen rechtwinklig abgehenden Federarme 14 ist derart bemessen, dass ein Außenumfang eines durch die Federarme 14 gebildeten Kranzes 26 in etwa dem Innenumfang des Glockenendes 8 entspricht.The contact webs 22 are circumferentially separated from each other by slits formed by punching. In the same way, the spring arms 14 are separated from each other. The ring segment 18 forms a base of the shield connection 16 around which both the spring arms 14 and the contact webs 22 are pivotable. The outer diameter of the ring segment 18 and the spring arms 14 which extend substantially at right angles to it are dimensioned such that an outer circumference of a ring 26 formed by the spring arms 14 corresponds approximately to the inner circumference of the bell end 8.

Das Ringsegment 18 hat in gleichmäßigem Abstand in Umfangsrichtung verteilt ausgebildete Bohrungen 28. Das innere stirnseitige Ende des Gehäusekopfteiles 4 ist von Zapfen 30 überragt, die einen verdickten Zapfenkopf 32 aufweisen. Korrespondierend hierzu hat das Gehäusebasisteil 4 Zapfenaufnahmen 34 zur verdrehsicheren Halterung des Gehäusebasisteils 4 relativ zu dem Gehäusekopfteil 6. Die Zapfenaufnahmen 34 bilden dabei in Richtung auf das Gehäusekopfteil 6 Anschläge 36 für die Zapfenköpfe 32 aus, so dass das Gehäusebasisteil 4 und das Gehäusekopfteil 6 auch in axialer Richtung bezogen auf die Längserstreckung eines zugeführten Kabels 38 unverlierbar miteinander verbunden sind.The annular segment 18 has bores 28 which are distributed at equal intervals distributed in the circumferential direction. The inner end face of the housing head part 4 is surmounted by pins 30, which have a thickened pin head 32. Corresponding to this, the housing base part 4 pin receptacles 34 for rotationally secure mounting of the housing base part 4 relative to the housing head part 6. The pin receivers 34 form in the direction of the housing head part 6 stops 36 for the journal heads 32, so that the housing base part 4 and the housing head part 6 in axial direction relative to the longitudinal extent of a supplied cable 38 are captively interconnected.

Das Gehäusebasisteil 4 besteht aus zwei Gehäuseschalenelementen 40, die identisch ausgebildet sind und jeweils zwei sich in Umfangsrichtung öffnende Aufnahmen 42 für an der gegenüberliegenden Randseite der Gehäuseschalenelemente 40 ausgebildete und die Randseite überragende Verriegelungszapfen 44 ausbildet. Jeweils eine freie Randseite einer Gehäuseschale 40 weist eine Gehäusebasisdichtlippe 46 auf, die eine der mit Bezugszeichen 48 gekennzeichneten Randseiten der jeweiligen Gehäuseschalenelemente 40 überragt und in einer korrespondierend hierzu an der anderen Randseite des anderen Gehäuseschalenelementes 40 ausgeformten Dichtnut im Eingriff ist, so dass die beiden Gehäuseschalenelemente 40 im gefügten Zustand in Umfangsrichtung abgedichtet sind. Diese Gehäusebasisdichtlippen 46 sind jeweils einteilig mit Segmenten einer Kabeldichtlippe 50, die im Bereich einer Kabeldurchführung 52 des Gehäusebasisteils 4 ausgeformt sind, und Segmenten einer Dichtlippe 54, die an dem in Einführrichtung freien Ende des Gehäusebasisteils 4 zur dichtenden Anlage an ein Gehäuse 56 (vgl. Figur 3) angeordnet sind, verbunden. Das Ausbilden der Gehäusebasisdichtlippe 46 sowie der Segmente der Kabeldichtlippe 50 und der Dichtlippe 54 erfolgt üblicherweise durch Umspritzen eines Grundkörpers der jeweiligen Gehäuseschalenelemente 40 über einen einzigen Anspritzpunkt. Die jeweiligen Segmente von Kabeldichtlippe 50 und Dichtlippe 54 bilden im gefügten Zustand der Gehäuseschalenelement 40 eine umfänglich geschlossene Dichtungsanordnung aus. Dementsprechend ist das durch die Kabeldurchführung 52 hindurch geführte Kabel 38 dichtend in der Kabeldurchführung 52 gehalten. Feuchtigkeit kann nicht von außen und entlang eines Kabelmantels 58 in das Steckergehäuse 2 gelangen. In gleicher Weise abgedichtet ist das Steckergehäuse 2, namentlich allein das Gehäusebasisteil 4 durch eine umfänglich geschlossene Dichtlippe 54 gegenüber dem Gehäuse 56 abgedichtet.The housing base part 4 consists of two housing shell elements 40, which are of identical construction and respectively form two receptacles 42 which open in the circumferential direction and form locking lugs 44 formed on the opposite edge side of the housing shell elements 40 and projecting beyond the edge side. In each case, a free edge side of a housing shell 40 has a housing base sealing lip 46, which is one of the marked with reference numeral 48 edge sides of the respective housing shell elements 40 surmounted and in a corresponding thereto on the other edge side of the other housing shell member 40 formed sealing groove is engaged, so that the two housing shell elements 40 are sealed in the joined state in the circumferential direction. These housing base sealing lips 46 are each integrally formed with segments of a cable sealing lip 50, which are formed in the region of a cable gland 52 of the housing base part 4, and segments of a sealing lip 54, which at the free end in the insertion direction of the housing base part 4 for sealing engagement with a housing 56 (see. FIG. 3 ) are connected. The formation of the housing base sealing lip 46 and the segments of the cable sealing lip 50 and the sealing lip 54 is usually carried out by molding a base body of the respective housing shell elements 40 over a single injection point. The respective segments of cable sealing lip 50 and sealing lip 54 form a circumferentially closed sealing arrangement in the assembled state of the housing shell element 40. Accordingly, the cable 38 routed through the grommet 52 is sealingly held in the grommet 52. Moisture can not get into the plug housing 2 from the outside and along a cable sheath 58. Sealed in the same way, the connector housing 2, namely alone the housing base part 4 sealed by a circumferentially closed sealing lip 54 relative to the housing 56.

Das Gehäusekopfteil 6 weist vorliegend zwei Gehäusekopfsegmente 60 auf, die über ein Filmscharnier 62 miteinander verbunden sind. Einer gesonderten Abdichtung dieser Gehäusekopfsegmente 60 bedarf es nicht, da das Gehäusekopfteil 6 im gefügten Zustand in einer Aufnahme 64 des Gehäuses 56 angeordnet ist, welches über die Dichtlippe 54 nach außen abgedichtet ist (vgl. Figur 5). Eines der Gehäusekopfsegmente 60, welches im Folgenden als Gehäusekopfdeckel 66 bezeichnet wird, hat eine sich in Umfangsrichtung erstreckende Einführnut 68, die sich zu einer Randseite 70 des Gehäusekopfdeckels 66 öffnet und in Umfangsrichtung bis zu einer Steckkontaktaufnahme 72 ragt, welche einen der in Figur 2 gezeigten Steckkontakte 74 aufnimmt. Ein korrespondierend hierzu ausgebildeter Steckkontakt 76 ist in einer Ausnehmung des anderen Gehäusekopfsegmentes 60 aufgenommen und wird durch einen Haltezapfen 78, der an der in Einführrichtung vorderen Seite von einer halbkreisförmigen Trennwand 80 des Gehäusekopfdeckels 66 abragt, in Position gehalten. Zwei weitere Steckkontakte 82, 84 sind in zu der Trennebene der Gehäusekopfsegmente 60, 66 hin offenen Ausnehmungen eingelegt und dort fixiert. Bei geschlossenem Gehäusekopfteil 6 liegen diese Steckkontakte 82, 84 mit ihrer zwischen Vorsprüngen ausgebildeten Haltenut 86 auf Höhe der vervollständigten Trennwand 80, wobei die Vorsprünge die Trennwand 80 auf der Vorderseite und der Innenseite überragen und sind damit in axialer Richtung fixiert.In the present case, the housing head part 6 has two housing head segments 60, which are connected to one another via a film hinge 62. A separate sealing of these housing head segments 60 is not necessary since the housing head part 6 is arranged in the assembled state in a receptacle 64 of the housing 56 which is sealed to the outside via the sealing lip 54 (see FIG. One of the housing head segments 60, which is referred to below as the housing head cover 66, has a circumferentially extending Einführnut 68, which opens to an edge side 70 of the housing head cover 66 and projects in the circumferential direction up to a plug contact receptacle 72, which one of in FIG. 2 shown plug contacts 74 receives. A correspondingly designed plug contact 76 is received in a recess of the other housing head segment 60 and is held by a retaining pin 78 which protrudes at the front in the insertion direction of a semicircular partition wall 80 of the housing head cover 66 in position. Two further plug contacts 82, 84 are inserted into the parting plane of the housing head segments 60, 66 towards open recesses and fixed there. When the housing head part 6 is closed, these plug contacts 82, 84 lie with their between Projections formed retaining groove 86 at the level of the completed partition wall 80, wherein the projections project beyond the partition wall 80 on the front side and the inside and are thus fixed in the axial direction.

Zur Befestigung des Kabels 38 wird der Kabelmantel derart entfernt, dass einerseits die einzelnen elektrischen Adern 88, 90, 94 des Kabels 38 mit ihren zugehörigen Kabelmänteln stirnseitig an dem Kabel 38 freiliegen sowie eine Abschirmung 96 des Kabels 38 das freie Ende des Kabelmantels 58 geringfügig überragt. Die einzelnen Kabeladern 88 bis 94 werden in an sich bekannter Weise durch Crimpen mit den Steckkontakten 74, 76, 82, 84 verbunden. Die Steckkontakte 74, 82, 84 werden in das Gehäusekopfsegment 60 eingelegt. Die dem Steckkontakt 74 zugeordnete Ader 90, d.h. das isolierte Kabel wird durch die Einführnut 68 geführt. Der Steckkontakt 74 wird in die Steckkontaktaufnahme 72 eingelegt. Danach wird der Gehäusekopfdeckel 66 um das Filmscharnier 62 verschwenkt und das Gehäusekopfteil 6 verschlossen.To attach the cable 38 of the cable sheath is removed so that on the one hand, the individual electrical wires 88, 90, 94 of the cable 38 with its associated cable sheaths frontally exposed to the cable 38 and a shield 96 of the cable 38 slightly surmounted the free end of the cable sheath 58 , The individual cable cores 88 to 94 are connected in a conventional manner by crimping with the plug contacts 74, 76, 82, 84. The plug contacts 74, 82, 84 are inserted into the housing head segment 60. The wire 90 associated with the plug contact 74, i. the insulated cable is passed through the insertion groove 68. The plug contact 74 is inserted into the plug contact receptacle 72. Thereafter, the housing head cover 66 is pivoted about the film hinge 62 and the housing head part 6 is closed.

Die zuvor auf den Kabelmantel aufgeschobene Schirmanbindung 16 wird nunmehr in axialer Richtung verschoben. Dabei verhaken die Kontaktstege mit der Abschirmung 96 und werden die Bohrungen 28 mit den Zapfen 30 zur Überdeckung gebracht. Diese Ausrichtung ist verhältnismäßig einfach zu handhaben, da wesentlich mehr Bohrungen 28 vorgesehen sind, als Zapfen 30 das Gehäusekopfteil 6 stirnseitig überragen. Es versteht sich von selbst, dass der Umfangsabstand zwischen benachbarten Zapfen 30 einem Vielfachen des Umfangsabstandes der Bohrungen 28 entspricht. Durch Eingriff der Zapfen 30 in die zugeordneten Bohrungen 28 ist das Gehäusekopfteil 6 in seiner geschlossenen Lage gesichert. Danach werden in radialer Richtung die Gehäuseschalenelemente 40 zugeführt, derart, dass die Zapfen 30 in die Zapfenaufnahmen 34 eingebracht werden. Die Verriegelungszapfen 44 greifen in die Aufnahmen 42 ein und verrasten hierin. Das Steckergehäuse 2 ist damit vervollständigt.The previously pushed onto the cable sheath shield 16 is now moved in the axial direction. In this case, the contact webs engage with the shield 96 and the holes 28 are brought to the pin 30 to cover. This orientation is relatively easy to handle, since significantly more holes 28 are provided as pin 30, the housing head part 6 project beyond the front. It goes without saying that the circumferential distance between adjacent pins 30 corresponds to a multiple of the circumferential distance of the holes 28. By engaging the pin 30 in the associated holes 28, the housing head part 6 is secured in its closed position. Thereafter, the housing shell elements 40 are fed in the radial direction, such that the pins 30 are inserted into the pin receivers 34. The locking pins 44 engage in the receptacles 42 and latch therein. The connector housing 2 is completed.

Zu Anschluss des so vorbereiteten Kabels 38 mit dem Stecker wird dieser in die Aufnahme 64 eingeschoben. Dabei gleiten die Federarme 14 zunächst an einer leicht konisch ausgebildeten und an dem Gehäuse 56 ausgebildeten Öffnung zu der Aufnahme 64 vorbei, so dass die Federarme 14 nach innen gedrängt werden. Im Zuge einer weiteren Einsteckbewegung gleiten am vorderen freien Ende der Federarme 14 ausgebildete Abschirmkontakte 98 an der Innenumfangsfläche der Aufnahme 64 vorbei. Die Steckbewegung findet ihr Ende, wenn das stirnseitige vordere Ende des Gehäusebasisteils 4 gegen eine die Aufnahme 64 umgebende Wandung des Gehäuses 56 stößt. Einander zugeordnete Befestigungselemente können vorgesehen sein, um das Gehäusebasisteil 4 mit dem Gehäuse 56 des Verbrauchers zu verbinden, so dass der Stecker unverlierbar gehalten ist. Die nach vorne geneigten Kontaktstege 22 können dabei als Zugentlastung wirken, die über die Abschirmung 96 das zugeführte Kabel 38 in Längsrichtung an dem Steckergehäuse 2 sichern.To connect the thus prepared cable 38 with the plug this is inserted into the receptacle 64. In this case, the spring arms 14 first slide past a slightly conical and formed on the housing 56 opening to the receptacle 64, so that the spring arms 14 are urged inwards. In the course of another insertion movement slide at the front free end of the spring arms 14 formed Abschirmkontakte 98 on the inner peripheral surface of the receptacle 64 over. The plug-in movement finds its end when the front-side front end of the housing base part 4 against a wall 64 surrounding the receptacle of the housing 56 abuts. Mutually associated fasteners may be provided to connect the housing base part 4 to the housing 56 of the consumer, so that the plug is held captive. The forwardly inclined contact webs 22 can act as a strain relief, which secure the supplied cable 38 in the longitudinal direction of the connector housing 2 via the shield 96.
