Offenbarung der Erfindung Disclosure of Invention
Aufgabe der Erfindung ist es, eine Steckverbindungseinrichtung zur Darstellung einer elektrischen Steckverbindung zwischen einem länglichen Kontaktstift und einem Kabelende eines Kabels herstellungstechnisch und/oder funktionell zu verbessern. The object of the invention is to improve a plug-in connection device for producing an electrical plug-in connection between an elongate contact pin and a cable end of a cable in terms of manufacturing technology and/or functionality.
Die Aufgabe ist bei einer Steckverbindungseinrichtung zur Darstellung einer elektrischen Steckverbindung zwischen einem länglichen Kontaktstift und einem Kabelende eines Kabels, dadurch gelöst, dass das Kabel in einem Steckergehäuse eine freie Kabellänge aufweist, die von dem Kabelende ausgeht, das an einer flexibel gelagerten Anschlussbuchse angebracht ist, in die der längliche Kontaktstift eingesteckt ist. Bei der elektrischen Steckverbindung handelt es sich vorzugsweise um eine Hochvoltverbindung einer elektrisch angetriebenen Luftzuführvorrichtung. Die Steckverbindungseinrichtung umfasst vorteilhaft drei Hochvoltverbindungen und eine Niedervoltverbindung. Durch die freie Kabellänge in dem Steckergehäuse wird der Ausgleich von herstellungsbedingten Toleranzen vereinfacht. Darüber hinaus kann mit der Steckverbindungseinrichtung ein Berührschutz sichergestellt werden. Des Weiteren werden flexible Abgangsrichtungen ermöglicht. Darüber hinaus werden sehr lange Kriech- und Luftstrecken ermöglicht. Der längliche Kontaktstift ist in einem Statorgehäuse angeordnet. In dem Statorgehäuse dienen vorzugsweise drei längliche Kontaktstifte zur Darstellung von Hochvoltverbindungen, die den Stator über die beanspruchte Steckverbindungseinrichtung mit einer separaten Steueranschlusseinrichtung verbinden. Bei der Steueranschlusseinrichtung handelt es sich vorzugsweise um einen Inverter. Die Anschlussbuchse hat zum Beispiel im Wesentlichen die Gestalt eines geraden Kreiszylindermantels. In der Anschlussbuchse ist zum Beispiel ein Lamellenkorb angeordnet. The object is achieved in a connector device for representing an electrical connector between an elongated contact pin and a cable end of a cable, characterized in that the cable in a Connector housing has a free cable length, which emanates from the cable end, which is attached to a flexibly mounted socket into which the elongated contact pin is inserted. The electrical plug connection is preferably a high-voltage connection of an electrically driven air supply device. The plug connection device advantageously includes three high-voltage connections and one low-voltage connection. The free cable length in the connector housing simplifies the compensation of production-related tolerances. In addition, protection against accidental contact can be ensured with the plug-in connection device. Furthermore, flexible outlet directions are made possible. In addition, very long creepage and clearance distances are made possible. The elongated contact pin is arranged in a stator housing. In the stator housing, three elongate contact pins are preferably used to represent high-voltage connections, which connect the stator to a separate control connection device via the claimed plug-in connection device. The control connection device is preferably an inverter. For example, the connection socket essentially has the shape of a straight circular cylinder shell. A lamellar basket, for example, is arranged in the connection socket.
Ein bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass die Anschlussbuchse für das Kabelende einen Kabelaufnahmekörper aufweist, dem ein C-Clip zugeordnet ist, der den Kabelaufnahmekörper außen umgreift, um eine Kabel-Ausreißsicherung darzustellen. Der Kabelaufnahmekörper ist vorzugsweise einstückig mit der Anschlussbuchse verbunden. Der Kabelaufnahmekörper hat zum Beispiel im Wesentlichen die Gestalt eines geraden Kreiszylindermantels, in den das Kabelende eingesteckt ist. Dabei ist das Kabelende vorteilhaft fest, insbesondere stoffschlüssig, mit dem Kabelende verbunden. Der C-Clip stützt sich im eingebauten Zustand vorteilhaft an einem Isolierkörper ab, der radial außerhalb des Kabelendes angeordnet ist. Darüber hinaus weist die Anschlussbuchse vorteilhaft einen Absatz auf, mit dem sich die Anschlussbuchse an dem C-Clip abstützt. So wird auf einfache Art und Weise verhindert, dass das Kabelende mit der Anschlussbuchse aus der Steckverbindungseinrichtung herausgerissen werden kann. Ein weiteres bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass die Anschlussbuchse in einer Zentriereinrichtung zentriert ist, die in einem Fangkäfig aufgenommen ist. Durch die Zentriereinrichtung wird die Anschlussbuchse mittig in dem Fangkäfig positioniert. A preferred exemplary embodiment of the plug-in connection device is characterized in that the connection socket for the cable end has a cable receiving body, to which a C-clip is assigned, which encompasses the cable receiving body on the outside in order to represent a cable protection against tearing out. The cable accommodating body is preferably connected in one piece to the connection socket. The cable receiving body has, for example, essentially the shape of a right circular cylinder shell into which the cable end is inserted. In this case, the cable end is advantageously firmly connected, in particular with a material connection, to the cable end. When installed, the C-clip is advantageously supported on an insulating body which is arranged radially outside of the end of the cable. In addition, the connection socket advantageously has a shoulder with which the connection socket is supported on the C-clip. This is a simple way of preventing the cable end with the connection socket from being torn out of the plug-in connection device. A further preferred exemplary embodiment of the plug connection device is characterized in that the connection socket is centered in a centering device which is accommodated in a catch cage. The connection socket is positioned in the center of the catch cage by the centering device.
Ein weiteres bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass die Zentriereinrichtung zwei Zentrierringe umfasst, mit denen die Zentriereinrichtung in dem Fangkäfig positioniert ist. Mit den Zentrierringen kann die Zentriereinrichtung einfach und stabil in dem Fangkäfig positioniert werden. A further preferred exemplary embodiment of the plug connection device is characterized in that the centering device comprises two centering rings with which the centering device is positioned in the catch cage. With the centering rings, the centering device can be easily and stably positioned in the capture cage.
Ein weiteres bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass die Zentrierringe durch Längsstege verbunden sind, von denen Zentrierarme ausgehen, die federnd an der Anschlussbuchse anliegen. So wird auf einfache Art und Weise eine kostengünstig herstellbare Zentriereinrichtung geschaffen. Die Zentrierringe stellen mit den Längsstegen eine Art Zentrierkäfig dar, von dem die Zentrierarme nach innen abgewinkelt beziehungsweise vorgespannt sind, so dass die Zentrierarme mit ihren freien Enden außen an der Anschlussbuchse anliegen. So kann die Anschlussbuchse zusätzlich zu der gewünschten Zentrierung gleichzeitig federnd in der Zentriereinrichtung gelagert werden. Dadurch wird der gewünschte Toleranzausgleich erheblich vereinfacht. A further preferred exemplary embodiment of the plug-in connection device is characterized in that the centering rings are connected by longitudinal webs, from which centering arms emanate and bear resiliently against the connection socket. In this way, a centering device that can be produced inexpensively is created in a simple manner. The centering rings represent a kind of centering cage with the longitudinal webs, from which the centering arms are angled or prestressed inward, so that the centering arms rest with their free ends on the outside of the connection socket. In addition to the desired centering, the connection socket can also be spring-mounted in the centering device at the same time. This considerably simplifies the desired tolerance compensation.
Ein weiteres bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass die freie Kabellänge innerhalb eines Isolierkörpers angeordnet ist, der mit dem Fangkäfig zusammengesteckt ist. Durch den Isolierkörper wird die freie Kabellänge in dem Steckergehäuse nach außen sicher abgeschirmt. Der Isolierkörper ist zu diesem Zweck aus einem elektrisch isolierenden Material gebildet. Durch die Steckverbindung zwischen dem Isolierkörper und dem Fangkäfig wird die Montage der Steckverbindungseinrichtung, insbesondere in Kombination mit dem vorab beschriebenen C-Clip, erheblich vereinfacht. Der Fangkäfig weist vorteilhaft für jede Anschlussbuchse einen Aufnahmekörper auf, der im Wesentlichen die Gestalt eines geraden Kreiszylindermantels aufweist.

A further preferred exemplary embodiment of the plug connection device is characterized in that the free cable length is arranged inside an insulating body which is plugged together with the catch cage. The free length of cable in the connector housing is safely shielded from the outside by the insulator. For this purpose, the insulating body is formed from an electrically insulating material. The plug-in connection between the insulating body and the retaining cage considerably simplifies the assembly of the plug-in connection device, in particular in combination with the C-clip described above. The catch cage advantageously has a receiving body for each connection socket, which essentially has the shape of a straight circular cylinder jacket. In each of these Recording body is advantageously arranged a socket with the interposition of a centering device. The receiving bodies are advantageously connected to one another in one piece on the collecting cage via a connecting body. The catch cage is advantageously detachably connected to the insulating body. In this context, detachable means that it can be repeatedly separated without destroying it. The detachable connection includes, for example, three screws with which the catch cage is screwed to the insulating body.
Ein weiteres bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass ein Dichtelement in dem Steckergehäuse an dem Fangkäfig anliegt. Dadurch wird eine platzsparende Abdichtung an dem Steckergehäuse ermöglicht. Das Dichtelement liegt vorzugsweise unmittelbar an dem Steckergehäuse und dem Fangkäfig an. A further preferred exemplary embodiment of the plug-in connection device is characterized in that a sealing element in the plug housing bears against the catch cage. This enables space-saving sealing on the connector housing. The sealing element is preferably in direct contact with the plug housing and the catch cage.
Ein weiteres bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass das Steckergehäuse einen Kabelabgang mit einer Schirmhülse und einem Schirmblech umfasst. Um einen guten Ausreißschutz der Schirmanwendung zu erreichen, ist das Schirmblech vorteilhaft mit abstehenden Rastnasen versehen, die in einen Freistich an der Schirmhülse hineinragen und als Widerhaken fungieren. A further preferred exemplary embodiment of the plug connection device is characterized in that the plug housing comprises a cable outlet with a shielding sleeve and a shielding plate. In order to achieve good protection against tearing out of the shielding application, the shielding plate is advantageously provided with protruding locking lugs which protrude into an undercut on the shielding sleeve and act as barbs.
Ein weiteres bevorzugtes Ausführungsbeispiel der Steckverbindungseinrichtung ist dadurch gekennzeichnet, dass der Kabelabgang in einem Ringraum zwischen dem Kabel und dem Steckergehäuse eine Dichtung aufweist, die in einer Kabellängsrichtung zwischen der Schirmhülse und einem nach innen abgewinkelten Kragen einer Verschlusskappe positioniert ist. Die Schirmhülse hintergreift vorteilhaft einen Absatz an dem Kabel. Das Schirmblech dient vorteilhaft dazu, die Schirmhülse mit dem Kabel in dem Steckergehäuse zu halten. Die Verschlusskappe umgreift vorteilhaft jeweils einen Kabelabgang außen an dem Steckergehäuse. Zu diesem Zweck ist die Verschlusskappe vorteilhaft mit Schnapphaken ausgestattet, die außen an dem Steckergehäuse einschnappen. A further preferred exemplary embodiment of the plug-in connection device is characterized in that the cable outlet has a seal in an annular space between the cable and the plug housing, which is positioned in a cable longitudinal direction between the shielding sleeve and an inwardly angled collar of a sealing cap. The shield sleeve advantageously engages behind a shoulder on the cable. The shielding plate advantageously serves to hold the shielding sleeve with the cable in the connector housing. The closure cap advantageously encompasses a respective cable outlet on the outside of the connector housing. For this purpose, the closure cap is advantageously equipped with snap hooks that snap into place on the outside of the connector housing.
Die Erfindung betrifft des Weiteren ein Steckergehäuse, eine Anschlussbuchse, eine Zentriereinrichtung, einen Isolierkörper, ein Dichtelement, eine Schirmhülse, ein Schirmblech und/oder eine Verschlusskappe für eine vorab beschriebene Steckverbindungseinrichtung.

In Figur 1 ist eine Luftzuführvorrichtung 1 perspektivisch dargestellt. Die Luftzuführvorrichtung 1 wird auch als Luftverdichter bezeichnet und dient in einem mobilen Brennstoffzellensystem zur Bereitstellung von verdichteter Luft. Das mobile Brennstoffzellensystem wiederum dient in einem mit dem Brennstoffzellensystem ausgestatteten Kraftfahrzeug zur Bereitstellung von elektrischer Energie, die zum Beispiel über einen Elektromotor in Antriebsenergie für das Kraftfahrzeug umgewandelt wird. In Figure 1, an air supply device 1 is shown in perspective. The air supply device 1 is also referred to as an air compressor and is used in a mobile fuel cell system to provide compressed air. In turn, the mobile fuel cell system is used in a motor vehicle equipped with the fuel cell system to provide electrical energy, which is converted, for example, via an electric motor into drive energy for the motor vehicle.
Die Luftzuführvorrichtung 1 umfasst ein mehrteiliges Gehäuse 2 mit einem Luftanschluss 3, über den Luft zugeführt wird, und mit einem Luftanschluss 4, über den verdichtete Luft abgeführt wird. Zum Verdichten der Luft umfasst die Luftzuführvorrichtung 1 zum Beispiel ein Verdichterrad, das innerhalb einer Verdichtervolute drehbar ist. Der Antrieb des Verdichterrads erfolgt durch einen Elektromotor, der in dem Gehäuse 2 angeordnet ist. Der Elektromotor umfasst einen Rotor, der innerhalb eines Stators drehbar ist. The air supply device 1 comprises a multi-part housing 2 with an air connection 3, via which air is supplied, and with an air connection 4, via which compressed air is discharged. In order to compress the air, the air supply device 1 comprises, for example, a compressor wheel which can be rotated within a compressor volute. The compressor wheel is driven by an electric motor which is arranged in the housing 2 . The electric motor includes a rotor rotatable within a stator.
Der Stator des Elektromotors umfasst eine Stromanschlusseinrichtung 5, über welche dem Stator Wechselstrom in drei Phasen zugeführt wird. Die Stromanschlusseinrichtung 5 ist über eine Verbindungseinrichtung 10, die drei längliche Kontaktteile 7, 8, 9 umfasst, mit einer Steueranschlusseinrichtung 6 verbunden. The stator of the electric motor includes a power connection device 5, via which alternating current is supplied to the stator in three phases. The power connection device 5 is connected to a control connection device 6 via a connection device 10 which comprises three elongate contact parts 7 , 8 , 9 .
Die Steueranschlusseinrichtung 6 ist zum Beispiel mit einem Kabelabgang 40 kombiniert, der, wie durch drei angedeutete abgehende Kabel 39 angedeutet ist, an einen separat angeordneten und in Figur 1 nicht dargestellten Inverter angeschlossen ist. Der Inverter kann aber auch in das Gehäuse 2 der Luftzuführvorrichtung 1 integriert sein. Dann entfällt der Kabelabgang 40. The control connection device 6 is combined, for example, with a cable outlet 40 which, as indicated by three outgoing cables 39, is connected to a separately arranged inverter and not shown in FIG. However, the inverter can also be integrated into the housing 2 of the air supply device 1 . Then the cable outlet 40 is omitted.
In den Figuren 2 bis 8 ist eine Steckverbindungseinrichtung 20 in verschiedenen Ansichten dargestellt. Darüber hinaus sind verschiedene Zustände der Steckverbindungseinrichtung 20 perspektivisch dargestellt, um die Montage der Steckverbindungseinrichtung 20 zu veranschaulichen. In the figures 2 to 8, a plug-in connection device 20 is shown in different views. In addition, various states of the plug-in connection device 20 are shown in perspective in order to illustrate the assembly of the plug-in connection device 20 .
In den Figuren 7 und 8 sieht man, dass ein Kabelabgang 40 der Steckverbindungseinrichtung 20 insgesamt drei Hochvoltanschlussleitungen 21, 22, 23 und eine Niedervoltanschlussleitung 24 umfasst. In Figur 8 ist angedeutet, dass die abgehenden Hochvoltanschlussleitungen 21, 22, 23 über die Steckverbindungseinrichtung 20 elektrisch mit Statorleitungen 51, 52, 53 eines nicht dargestellten Stators verbunden sind. In FIGS. 7 and 8 one can see that a cable outlet 40 of the plug-in connection device 20 comprises a total of three high-voltage connection lines 21 , 22 , 23 and a low-voltage connection line 24 . FIG. 8 indicates that the outgoing high-voltage connection lines 21, 22, 23 are electrically connected via the plug-in connection device 20 to stator lines 51, 52, 53 of a stator (not shown).
Der Stator ist innerhalb eines Statorgehäuses 13 angeordnet, das einen Statorgehäusekörper 14 und einen Statorgehäusekörper 15 umfasst. Die beiden Statorgehäusekörper 14, 15 sind unter Zwischenschaltung einer Dichteinrichtung 17 zusammengebaut. Von den Statorleitungen erstreckt sich jeweils eine Stromschiene 12 durch den Statorgehäusekörper 14. In Figur 2 sieht man, dass die Stromschiene 17 mit einem länglichen Kontaktstift 11 verbunden ist. Im Inneren des Statorgehäusekörpers 15 ist eine optionale Kühleinrichtung 16 vorgesehen. An die Niedervoltanschlussleitung 24 ist zum Beispiel eine Sensoreinrichtung angeschlossen. The stator is arranged within a stator housing 13 which includes a stator housing body 14 and a stator housing body 15 . The two stator housing bodies 14, 15 are assembled with a sealing device 17 interposed. A busbar 12 extends from each of the stator lines through the stator housing body 14. In FIG. 2 one can see that the busbar 17 is connected to an elongated contact pin 11 . An optional cooling device 16 is provided inside the stator housing body 15 . A sensor device, for example, is connected to the low-voltage connection line 24 .
Die Steckverbindungseinrichtung 20 umfasst ein Steckergehäuse 25 mit einer Anschlussbuchse 30, in der das in Figur 2 rechte Ende des länglichen Kontaktstiftes 11 eingesteckt ist. Die Anschlussbuchse 30 ist aus einem elektrisch gut leitenden Material gebildet und einstückig mit einem Kabelaufnahmekörper 29 verbunden. The plug connection device 20 comprises a plug housing 25 with a connection socket 30, in which the end of the elongate contact pin 11 on the right in FIG. 2 is inserted. The connection socket 30 is formed from a material with good electrical conductivity and is connected in one piece to a cable receiving body 29 .
In dem Kabelaufnahmekörper 29 ist ein Kabelende 27 eines Kabels 26 befestigt. Das Kabel 26 umfasst eine freie Kabellänge 28, die in dem Steckergehäuse 25 angeordnet ist. An dem Kabelabgang 40 ist das Kabel 26 aus dem Steckergehäuse 25 herausgeführt. A cable end 27 of a cable 26 is fastened in the cable receiving body 29 . The cable 26 includes a free length of cable 28 which is arranged in the plug housing 25 . The cable 26 is routed out of the connector housing 25 at the cable outlet 40 .
Das Kabelende 27 ist mit dem Kabelaufnahmekörper 29 und der einstückig damit verbundenen Anschlussbuchse 30 durch einen C-Clip 31 in dem Steckergehäuse 25 gehalten. So wird auf einfache Art und Weise ein unerwünschtes Herausreißen des Kabels 26 aus dem Steckergehäuse 25 sichergestellt. The cable end 27 is held in the connector housing 25 by a C-clip 31 with the cable receiving body 29 and the connection socket 30 connected to it in one piece. In this way, an undesired tearing out of the cable 26 from the connector housing 25 is ensured in a simple manner.
Das Kabelende 27 ist über die Anschlussbuchse 30 elektrisch leitend mit dem länglichen Kontaktstift 11 verbunden. Abgesehen von der Anschlussbuchse 30 sind die Einzelteile der Steckverbindungseinrichtung 20 vorzugsweise aus einem nicht oder schlecht elektrisch leitenden Material gebildet. The cable end 27 is electrically conductively connected to the elongated contact pin 11 via the connection socket 30 . Apart from the connection socket 30, the individual parts of the plug-in connection device 20 are preferably formed from a material which is not electrically conductive or has a poor electrical conductivity.
Die Anschlussbuchse 30 ist mit Hilfe einer Zentriereinrichtung 32 innerhalb eines Fangkäfigs 33 zentriert und federnd gelagert. Zur Abdichtung des Steckergehäuses 25 ist ein Dichtelement 34 zwischen dem Fangkäfig 33 und dem Steckergehäuse 25 angeordnet. So wird auf einfache Art und Weise eine Abdichtung zwischen dem Statorgehäusekörper 15 und dem Steckergehäuse 25 realisiert. The connection socket 30 is centered with the aid of a centering device 32 within a catch cage 33 and is resiliently mounted. A sealing element 34 is arranged between the catch cage 33 and the plug housing 25 to seal the plug housing 25 . A seal between the stator housing body 15 and the connector housing 25 is thus implemented in a simple manner.
Der Fangkäfig 33 ist mit einem Isolierkörper 35 zusammengesteckt, der die freie Kabellänge 28 in dem Steckergehäuse 25 mit ausreichend Spiel umgibt, um einen ausreichenden Toleranzausgleich zu ermöglichen. Der Isolierkörper 35 ist, wie sich aus einer Zusammenschau der Figuren 2, 3 und 7 ergibt, mit Hilfe von Schrauben 48, 49, 50 zusammen mit dem Fangkäfig 33 in dem Steckergehäuse 25 fixiert. The catch cage 33 is mated with an insulator 35 which surrounds the free length of cable 28 in the connector housing 25 with sufficient play to to allow sufficient tolerance compensation. 2, 3 and 7 together, the insulating body 35 is fixed in the connector housing 25 together with the retaining cage 33 with the aid of screws 48, 49, 50.
In Figur 3 sieht man, dass die Zentriereinrichtung 32 jeweils zwei Zentrierringe 44, 45 umfasst, die durch Längsstege 46 miteinander verbunden sind. Von den Längsstegen 46 gehen Zentrierarme 47 aus. In FIG. 3 one can see that the centering device 32 comprises two centering rings 44 , 45 which are connected to one another by longitudinal webs 46 . Centering arms 47 extend from the longitudinal webs 46 .
Mit den Zentrierringen 44, 45 ist die Zentriereinrichtung 32 in dem Fangkäfig 33 positioniert. Die Anschlussbuchse 30 wird durch die Zentrierarme 47 zentriert und federnd gelagert. The centering device 32 is positioned in the catch cage 33 with the centering rings 44 , 45 . The connection socket 30 is centered by the centering arms 47 and is resiliently mounted.
In Figur 4 sieht man, dass die Steckverbindungseinrichtung 20 für jede Hochvoltanschlussleitung eine Anschlussbuchse 30 umfasst. Die Anschlussbuchsen 30 werden durch die C-Clips 31 gehalten. Dabei werden die C-Clips 31 erst aufgesteckt, nachdem die Kabeln 26 mit den Anschlussbuchsen 30 montiert sind und der Isolierkörper 35 im Steckergehäuse 25 platziert ist. Anschließend wird der Fangkäfig 33 mit den eingebauten Zentriereinrichtungen 32 auf den Isolierkörper 35 aufgesetzt und zusammen mit diesem durch die Schrauben 48, 49, 50 im Steckergehäuse 25 befestigt, wie in Figur 7 veranschaulicht ist. FIG. 4 shows that the plug-in connection device 20 includes a connection socket 30 for each high-voltage connection line. The sockets 30 are held by the C-clips 31. The C-clips 31 are only attached after the cables 26 have been fitted with the connection sockets 30 and the insulating body 35 has been placed in the connector housing 25 . Then the catch cage 33 with the built-in centering devices 32 is placed on the insulating body 35 and fastened together with this by the screws 48, 49, 50 in the connector housing 25, as illustrated in FIG.
In den Figuren 5 und 6 ist gezeigt, dass am Kabelabgang 40 für jedes abgehende Kabel 26 eine Schirmhülse 36 und ein Schirmblech 37 angeordnet ist. Die Schirmhülse 36 umgreift einen umlaufenden Absatz 43 an dem Kabel 36. Das Schirmblech 37 ist in einem Ringraum zwischen der Schirmhülse 36 und dem Steckergehäuse 25 aufgenommen. FIGS. 5 and 6 show that a shielding sleeve 36 and a shielding plate 37 are arranged on the cable outlet 40 for each outgoing cable 26 . The shielding sleeve 36 surrounds a circumferential shoulder 43 on the cable 36. The shielding plate 37 is accommodated in an annular space between the shielding sleeve 36 and the plug housing 25.
Das Schirmblech 37 ist mit Widerhaken 38 ausgestattet, die in die Schirmhülse 36 einhaken und so einen Ausreißschutz der Schirmanbindung zu erreichen. Die Widerhaken 38 sind zum Beispiel als abstehende Rastnasen an dem Schirmblech 37 ausgeführt und greifen widerhakenartig in einen entsprechenden Freistich an der Schirmhülse 36. Eine Dichtung 42 ist in axialer Richtung zwischen der mit dem Schirmblech 37 kombinierten Schirmhülse 36 und einem nach innen abgewinkelten Kragen 54 einer Verschlusskappe 41 positioniert. Die Dichtung 42 dichtet radial zwischen dem Kabel 26 und dem Steckergehäuse 25 ab. The shielding plate 37 is equipped with barbs 38 which hook into the shielding sleeve 36 and thus protect the shielding connection from being pulled out. The barbs 38 are designed, for example, as protruding latching lugs on the shielding plate 37 and engage in a barb-like undercut on the shielding sleeve 36. A seal 42 is positioned in the axial direction between the shielding sleeve 36 combined with the shielding plate 37 and an inwardly angled collar 54 of a closure cap 41 . The seal 42 provides a radial seal between the cable 26 and the plug housing 25 .
