Description

Titel: LADEBUCHSE FÜR EINEN ELEKTRISCHEN ENERGIESPEICHER Title: CHARGING SOCKET FOR AN ELECTRICAL ENERGY STORAGE
Die Erfindung betrifft eine Ladebuchse für einen elektrischen Energiespeicher, mit mindestens zwei Leistungskontakten, die jeweils elektrisch mit einem geschirmten Leistungskabel verbunden sind, und mit einer Masseleiteranordnung zur Verbindung von Schirmhüllen der Leistungskabel mit einer Masse des Energiespeichers. The invention relates to a charging socket for an electrical energy storage device, with at least two power contacts which are each electrically connected to a shielded power cable, and with a ground conductor arrangement for connecting the shielding sleeves of the power cables to a ground of the energy storage device.
Insbesondere befasst sich die Erfindung mit Ladebuchsen für Elektrofahrzeuge. In particular, the invention deals with charging sockets for electric vehicles.
Wenn die Batterie eines Elektrofahrzeugs aufgeladen werden soll, so wird ein Ladegerät über ein Ladekabel und einen Ladestecker und über die von außen zugänglich an der Fahrzeugkarosserie angebrachte Ladebuchse mit der Batterie an Bord des Fahrzeugs verbunden. Beim Einstecken des Ladesteckers in die Ladebuchse werden die Leistungskontakte der Ladebuchse mit entsprechenden Gegenkontakten des Ladesteckers in Eingriff gebracht und elektrisch verbunden. Die Ladebuchse und der Ladestecker weisen darüber hinaus Steckverbinder für Signalleitungen auf, die zum Austausch von Steuersignalen zwischen dem Ladegerät und der Batterie und der zugehörigen Elektronik im Fahrzeug dienen. If the battery of an electric vehicle is to be charged, a charging device is connected to the battery on board the vehicle via a charging cable and a charging plug and via the charging socket which is attached to the vehicle body and is accessible from the outside. When the charging plug is inserted into the charging socket, the power contacts of the charging socket are brought into engagement with corresponding mating contacts of the charging plug and are electrically connected. The charging socket and the charging plug also have connectors for signal lines that are used to exchange control signals between the charger and the battery and the associated electronics in the vehicle.
Die Leistungskabel dienen dazu, den Ladestrom von den Leistungskontakten der Ladebuchse zur Batterie weiterzuleiten. Jedes Ladekabel weist eine zentrale Ader mit hoher Leitfähigkeit auf, deren Querschnitt für eine hohe Ladestromstärke ausgelegt ist. Die zentrale Ader ist von innen nach außen koaxial umgeben von einer inneren Isolierung, einer elektrisch leitfähigen und an Masse anzuschließenden Schirmhülle und einer äußeren Isolierung. In der Ladebuchse ist die zentrale Ader jedes Ladekabels an einen der Leistungskontakte angeschlossen, und die Schirmhülle jedes Ladekabels ist elektrisch mit der Masseleiteranordnung verbunden, die ihrerseits an einen Massekontakt der Batterie angeschlossen ist. The power cables are used to transfer the charging current from the power contacts of the charging socket to the battery. Each charging cable has a central core with high conductivity, the cross-section of which is designed for a high charging current. The central wire is coaxially surrounded from the inside to the outside by an inner insulation, an electrically conductive shielding sleeve that is to be connected to ground, and an outer insulation. In the charging socket, the central core of each charging cable is connected to one of the power contacts, and the shielding sleeve of each charging cable is electrically connected connected to the ground conductor arrangement, which in turn is connected to a ground contact of the battery.
Typischerweise sind die beiden Leistungskontakte nebeneinander in einer Ebene angeordnet, und auch die angeschlossenen Leistungskabel verlaufen parallel zueinander in dieser Ebene. Bei bekannten Ladebuchsen weist die Masseleiteranordnung eine Schirmabgriffbrille mit zwei achsparallelen Öffnungen auf, durch die Endabschnitte der Ladekabel, auf denen jeweils die äußere Isolierung entfernt ist, so hindurchgesteckt sind, dass die dann freiliegenden, zumeist aus einem Schirmgeflecht gebildeten Schirmhüllen an der inneren Umfängst läche der betreffenden Öffnung der Schirmabgriffbrille anliegen, so dass eine elektrisch leitende Verbindung zwischen der Schirmhülle und der Schirmabgriffbrille hergestellt wird. Typically, the two power contacts are arranged side by side on one level, and the connected power cables also run parallel to one another on this level. In known charging sockets, the ground conductor arrangement has shield tapping glasses with two axially parallel openings, through which the end sections of the charging cable, on which the outer insulation has been removed, are inserted in such a way that the shielding sleeves, which are then exposed and are usually formed from a braided shield, on the inner peripheral surface of the relevant opening of the shield tapping glasses abut so that an electrically conductive connection between the shielding sleeve and the shielding tap glasses is made.
Jenseits der Schirmabgriffbrille sind auf den Enden der Leistungskabel jeweils auch die Schirmhülle und die innere Isolierung entfernt, und die zentrale Ader ist in einem gewissen Abstand zur Schirmabgriffbrille an den zugehörigen Leistungskontakt angeschlossen. On the other side of the shield tapping glasses, the shielding sleeve and the inner insulation have also been removed at the ends of the power cables, and the central core is connected to the associated power contact at a certain distance from the shield tapping glasses.
Die Ladekabel weisen zwar eine gewisse Flexibilität auf, sind aber aufgrund des großen Leitungsquerschnitt der zentralen Ader relativ biegesteif, so dass die Kabel im Fahrzeug nur mit entsprechend großen Krümmungsradien verlegt werden können. Das setzt voraus, dass im Fahrzeug ausreichend Bauraum vorhanden ist. Although the charging cables have a certain flexibility, they are relatively rigid due to the large cable cross-section of the central wire, so that the cables can only be laid in the vehicle with correspondingly large radii of curvature. This assumes that there is sufficient installation space in the vehicle.

DE 102008006340 A1 , DE 102019 120373 A1 , US 2005/0164543 A1 und US 2013/0029524 A1. DE 102008006340 A1, DE 102019 120373 A1, US 2005/0164543 A1 and US 2013/0029524 A1.
Aufgabe der Erfindung ist es, eine Ladebuchse zu schaffen, die ein raumsparendes Verlegen der Leistungskabel erleichtert. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Masseleiteranordnung mindestens zwei separate, jeweils mit einem Masseleiter verbundene Schirmabgriffelemente aufweist, die in Längsrichtung der Leistungskabel relativ zueinander beweglich sind. The object of the invention is to create a charging socket that facilitates space-saving laying of the power cable. This object is achieved according to the invention in that the ground conductor arrangement has at least two separate shield tapping elements, each connected to a ground conductor, which can be moved relative to one another in the longitudinal direction of the power cables.
Da die Schirmabgriffelemente relativ zueinander beweglich sind, brauchen sie in Längsrichtung der Leistungskabel nicht auf gleicher Höhe zu liegen. Dadurch wird es möglich, die Leistungskabel so anzuordnen, dass ihre Längsachsen bereits an der Stelle der Schirmabgriffelemente einen Winkel mit der Längsachse des jeweils zugehörigen Leistungskontakts bilden. Folglich können die Leistungskabel bereits auf den zwischen den Leistungskontakten und den Schirmabgriffelementen liegenden Endabschnitten in eine jeweils gewünschte Richtung geneigt oder gebogen sein. Dadurch wird es erleichtert, die Leistungskabel an Bauteilen vorbeizuführen, die innerhalb der Fahrzeugkarosserie in einem gewissen Abstand hinter der Ladebuchse liegen. Since the shield tapping elements can be moved relative to one another, they do not have to be at the same height in the longitudinal direction of the power cables. This makes it possible to arrange the power cables in such a way that their longitudinal axes already form an angle with the longitudinal axis of the respectively associated power contact at the location of the shield tapping elements. Consequently, the power cables can already be inclined or bent in a respectively desired direction on the end sections located between the power contacts and the shield tapping elements. This makes it easier to route the power cables past components that are located within the vehicle body at a certain distance behind the charging socket.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous refinements and developments of the invention are specified in the dependent claims.
In einer Ausführungsform sind die Schirmabgriffelemente in einem Gehäuse untergebracht, das an einem Ende Durchführungen für die Leistungskabel aufweist und am entgegengesetzten Ende flexibel mit einem Kontaktträger für die Leistungskontakte verbunden ist. Auf diese Weise können die elektrischen Komponenten gegen Berührung und Umwelteinflüsse geschützt werden, und dennoch wird hinsichtlich der Orientierung und des Verlaufs der Leitungskabel eine hohe Variabilität erreicht. In one embodiment, the shield tapping elements are accommodated in a housing which has bushings for the power cables at one end and is flexibly connected to a contact carrier for the power contacts at the opposite end. In this way, the electrical components can be protected against contact and environmental influences, and yet a high level of variability is achieved with regard to the orientation and routing of the cables.
Die Enden der leitenden Adern der Leistungskabel können mit den Leistungskontakten über L-förmige Kontaktfahnen verbunden sein, deren Schenkel einen Winkel miteinander bilden, der den Winkel zwischen den Längsachsen der Leistungskontakte und den Längsachsen der Leistungskabel bestimmt. Dieser Winkel kann somit einfach variiert werden, indem die Kontaktfahnen gegen solche mit einem anderen Winkel ausgetauscht werden oder ggf. auch in eine andere Form gebogen werden. The ends of the conductive cores of the power cables can be connected to the power contacts via L-shaped contact lugs, the legs of which form an angle with each other that equals the angle between the Longitudinal axes of the power contacts and the longitudinal axes of the power cables are determined. This angle can thus be easily varied by exchanging the contact lugs for those with a different angle or, if necessary, by bending them into a different shape.
Die mit den Schirmabgriffelementen verbundenen Masseleiter können innerhalb der Ladebuchse einen flexiblen Abschnitt aufweisen, der die Relativbewegung der Schirmabgriffelemente ermöglicht. Die den Schirmabgriffelementen entgegengesetzten Enden dieser flexiblen Abschnitte können dann noch innerhalb der Ladebuchse zu einem einzigen Masseleiter vereinigt werden, der über eine Durchführung aus dem Gehäuse herausgeführt ist. Im Folgenden werden Ausführungsbeispiele anhand der Zeichnung näher erläutert. The ground conductors connected to the shield tapping elements can have a flexible section within the charging socket, which allows the relative movement of the shield tapping elements. The ends of these flexible sections opposite the shield tapping elements can then still be combined inside the charging socket to form a single ground conductor, which is led out of the housing via a bushing. Exemplary embodiments are explained in more detail below with reference to the drawing.

Am fahrzeuginneren Ende ist der Isolierkörper 14 durch 5 einen scheibenförmigen Kontaktträger 16 abgeschlossen, in dem mittels Halteklammern 17 (schematisch in Fig. 2 dargestellt) zwei Leistungskontakte 18 so gehalten sind, dass sie parallel nebeneinander liegen und axial in das Innere des Isolierkörpers 14 hineinragen. Wenn der Stecker des Ladekabels eingesteckt wird, treten diese Leistungskontakte 18 mit entsprechenden Gegenkontakten des Steckers in Eingriff. Die zum Fahrzeuginneren weisenden Enden der Leistungskontakte 18 sind jeweils über eine L-förmige Kontaktfahne 20 mit einer leitenden zentralen Ader 22 eines Leistungskabels 24 verbunden. At the end inside the vehicle, the insulating body 14 is closed off by a disc-shaped contact carrier 16, in which two power contacts 18 are held by means of retaining clips 17 (shown schematically in Fig. 2) in such a way that they lie parallel to one another and protrude axially into the interior of the insulating body 14. When the plug of the charging cable is plugged in, these power contacts 18 engage corresponding mating contacts of the plug. The ends of the power contacts 18 pointing toward the interior of the vehicle are each connected to a conductive central wire 22 of a power cable 24 via an L-shaped contact lug 20 .
An den Kontaktträger 16 ist ein Ringdeckel 26 angeflanscht, der einen koaxialen Haltestutzen 28 für ein isolierendes Gehäuse 30 trägt, das hier nur strichpunktiert und transparent dargestellt ist. Im Boden des topfförmigen Gehäuses 30 sind zwei parallele Durchführungen 32 für die Leistungskabel 24 gebildet. Außerdem bildet der Boden des Gehäuses 30 noch mindestens eine Durchführung 34 für ein Signalkabel und mindestens eine Durchführung 36 für einen Masseleiter. A ring cover 26 is flanged to the contact carrier 16 and carries a coaxial holding piece 28 for an insulating housing 30, which is shown here only in broken lines and transparently. Two parallel bushings 32 for the power cables 24 are formed in the bottom of the pot-shaped housing 30 . In addition, the bottom of the housing 30 forms at least one passage 34 for a signal cable and at least one passage 36 for a ground conductor.
Das an die Ladebuchse anzuschließende Ladekabel enthält neben zwei Hauptleitern für den Ladestrom auch mehrere Signalleitungen, über die Steuersignale zwischen dem Ladegerät und der Batterieelektronik im Fahrzeug ausgetauscht werden. Die Ladebuchse weist Steckverbinder auf, die hier der Übersichtlichkeit halber nicht dargestellt sind. Diese Steckverbinder verbinden die Signalleiter des Ladekabels mit dem erwähnten Signalkabel, das durch die Durchführung 34 nach außen geführt wird. In addition to two main conductors for the charging current, the charging cable to be connected to the charging socket also contains several signal lines, via which control signals are exchanged between the charging device and the battery electronics in the vehicle. The charging socket has plug connectors, which are not shown here for the sake of clarity. These connectors connect the signal conductors of the charging cable to the signal cable mentioned, which is routed through the bushing 34 to the outside.
Um den Aufbau der Leistungskabel 24 zu erläutern, ist in Fig. 1 ein abisolierter Endabschnitt eines solchen Leistungskabels noch einmal gesondert dargestellt. Die zentrale Ader 22 (beispielsweise aus Kupfer) ist von einer inneren Isolierung 38 umgeben, die auf ihrem äußeren Umfang eine Schirmhülle 40 aus einem elektrisch leitenden Schirmgeflecht trägt. Diese Schirmhülle 40 ist von einer äußeren Isolierung 42 umgeben. Die Schirmhüllen 40 der Leistungskabel dienen dazu, die Umgebung der Kabel während des Ladevorgangs gegen elektromagnetische Felder abzuschirmen und die elektromagnetische Verträglichkeit (EMV) sicherzustellen. In order to explain the construction of the power cable 24, a stripped end section of such a power cable is shown again in FIG shown separately. The central wire 22 (made of copper, for example) is surrounded by an inner insulation 38, which carries a shielding sleeve 40 made of an electrically conductive braided shield on its outer circumference. This shielding sleeve 40 is surrounded by an outer insulation 42 . The shielding sleeves 40 of the power cables serve to shield the area around the cables against electromagnetic fields during the charging process and to ensure electromagnetic compatibility (EMC).
Im Gehäuse 30 der Ladebuchse ist für jedes Leistungskabel 24 ein ringförmiges Schirmabgriffelement 44 vorgesehen, das mit einer Crimphülse 46 einen abisolierten Abschnitt der Schirmhülle 40 eng umschließt und kontaktiert. Im gezeigten Beispiel sind die Schirmabgriffelemente insgesamt ringförmig ausgebildet und lediglich durch die Leistungskabel im Gehäuse 30 gehalten. Von jedem Schirmabgriffelement 44 geht ein Anschlussstift 48 aus, an den ein flexibler Masseleiter 50 (Fig. 2) anschließbar ist. Die Masseleiter sind über die Durchführung 36 gedichtet nach außen geführt. Wie sich deutlicher in Fig. 2 erkennen lässt, ist ein Längsabschnitt der Umfangswand des Gehäuses 30 als Faltenbalg 52 ausgeführt, so dass der Hauptteil des Gehäuses 30 flexibel mit dem Stutzen 28 des Ringdeckels 26 verbunden ist. In dem in Fig. 2 gezeigten Zustand sind die Achsen des zylindrischen Isolierkörpers 14 und des Gehäuses 30 nicht koaxial, sondern sie bilden einen Winkel miteinander. Dementsprechend bildet auch die Achse jedes Leistungskontakts 18 einen Winkel mit der Achse des zugehörigen Leistungskabels 24. Die Neigung der Leistungskabel 24 relativ zu den Leistungskontakten 18 wird im gezeigten Beispiel durch die Form der L- förmigen Anschlussfahnen 20 bestimmt, kann jedoch in gewissen Grenzen auch durch Biegung der innerhalb des Gehäuses 30 liegenden Abschnitte der Leistungskabel 24 variiert werden. Eine solche Neigung der Leistungskabel 24 relativ zu dem Inlet 10 und damit auch relativ zur Außenfläche der Karosserie kann beispielsweise dann von Vorteil sein, wenn sich weiter innen im Fahrzeug, auf der rechten Seite in Fig. 2, irgendwelche Fahrzeugbauteile befinden, an denen die Leistungskabel 24 vorbeigeführt werden müssen. In the housing 30 of the charging socket, a ring-shaped shield tapping element 44 is provided for each power cable 24, which closely encloses and contacts a stripped section of the shielding sleeve 40 with a crimp sleeve 46. In the example shown, the shield tapping elements are ring-shaped overall and are held in the housing 30 only by the power cables. A connecting pin 48 extends from each shield tapping element 44, to which a flexible ground conductor 50 (FIG. 2) can be connected. The ground conductors are routed to the outside via the bushing 36 in a sealed manner. As can be seen more clearly in FIG. 2 , a longitudinal section of the peripheral wall of the housing 30 is designed as a bellows 52 so that the main part of the housing 30 is flexibly connected to the socket 28 of the annular cover 26 . In the condition shown in Fig. 2, the axes of the cylindrical insulator 14 and the housing 30 are not coaxial, but they form an angle with each other. Accordingly, the axis of each power contact 18 also forms an angle with the axis of the associated power cable 24. The inclination of the power cable 24 relative to the power contacts 18 is determined in the example shown by the shape of the L-shaped connection lugs 20, but can also be determined within certain limits by Bending of the portions of the power cables 24 lying within the housing 30 can be varied. Such an inclination of the power cable 24 relative to the inlet 10 and thus also relative to the outer surface of the body can be advantageous, for example, if further inside the vehicle, on the right-hand side in FIG. are any vehicle components that the power cables 24 must be routed past.
In dem hier gezeigten Beispiel sind die Anschlussfahnen 20 durch Ultraschallschweißung starr mit den Enden der leitenden Adern 22 verbunden, während die quer zu den Leistungskontakten 18 verlaufenden Schenkel dieser Anschlussfahnen durch Schraubverbindungen an den Enden der Leistungskontakte fixiert sind. Die Neigungskonfiguration der Leistungskabel 24 kann somit bei der Herstellung der Ladebuchsen je nach Fahrzeugtyp variiert werden, indem Anschlussfahnen 20 verwendet werden, deren Schenkel einen anderen Winkel miteinander bilden. Gegebenenfalls können die mit den leitenden Adern verbundenen Schenkel der Anschlussfahnen auch eine gewisse Biegsamkeit aufweisen. In the example shown here, the terminal lugs 20 are rigidly connected to the ends of the conductive wires 22 by ultrasonic welding, while the legs of these terminal lugs running transversely to the power contacts 18 are fixed to the ends of the power contacts by screw connections. The configuration of inclination of the power cables 24 can thus be varied in the manufacture of the charging sockets, depending on the type of vehicle, by using terminal lugs 20 whose legs form a different angle with one another. If necessary, the legs of the terminal lugs connected to the conductive wires can also have a certain flexibility.
In anderen Ausführungsformen kann die Neigungsverstellung dadurch erreicht werden, dass die Leistungskontakte 18 und die leitenden Adern 22 auf irgendeine geeignete Weise elektrisch leitend und gelenkig miteinander verbunden sind. In other embodiments, the tilt adjustment may be accomplished by electrically conductively and hingedly connecting the power contacts 18 and the conductive strands 22 together in any suitable manner.
Die Enden der Leistungskabel 24 sind in dem in Fig. 2 gezeigten Beispiel auf identische Weise abisoliert worden, so dass sich die Abschnitte, in denen die Schirmhülle 40 freiliegt, bei beiden Kabel im gleichen Abstand zum Ende der leitenden Ader 22 befinden. Dementsprechend weisen auch die Schirmabgriffelemente 44 den gleichen Abstand zum Ende der leitenden Ader 22 auf. Der geneigte Verlauf der Leistungskabel 24 hat dann zur Folge, dass sich die Schirmabgriffelemente 44 in Axialrichtung des Gehäuses 30 und in Axialrichtung der Leistungskabel 24 nicht auf gleicher Höhe befinden. Da jedoch die beiden Schirmabgriffelemente 24 mechanisch vollständig voneinander getrennt sind und sich somit frei gegeneinander bewegen können, lässt sich die Neigung der Leistungskabel 24 frei wählen. In Fig. 2 sind strichpunktiert auch zwei flexible Masseleiter 50 gezeigt, die jeweils an einen der Anschlussstifte 48 angeschlossen sind und die zu der Durchführung 36 verlaufen. Diese Durchführung ist allerdings in Fig. 2 nicht erkennbar, da sie in einer gegenüber der Schnittebene versetzten Ebene liegt. Die beiden Masseleiter 50 können gemeinsam durch die Durchführung 36 hindurchgeführt sein. Wahlweise können sie jedoch auch noch innerhalb des Gehäuses 30 an einem gemeinsamen Anschlussleiter 54 angeschlossen sein, so dass nur dieser Anschlussleiter 54 durch die Durchführung hindurchgeführt zu werden braucht The ends of the power cables 24 have been stripped in an identical manner in the example shown in FIG. 2 so that the sections in which the shielding sleeve 40 is exposed are at the same distance from the end of the conductive wire 22 in both cables. Correspondingly, the shield tapping elements 44 are also at the same distance from the end of the conductive wire 22 . The inclined course of the power cables 24 then means that the shield tapping elements 44 are not at the same level in the axial direction of the housing 30 and in the axial direction of the power cables 24 . However, since the two shield tapping elements 24 are mechanically completely separate from one another and can therefore move freely in relation to one another, the inclination of the power cables 24 can be freely selected. Also shown in phantom in FIG. 2 are two flexible ground conductors 50 each connected to one of the terminal pins 48 and extending to the feedthrough 36 . However, this passage cannot be seen in FIG. 2, since it lies in a plane that is offset from the plane of section. The two ground conductors 50 can be passed through the bushing 36 together. Optionally, however, they can also be connected to a common connecting conductor 54 within the housing 30, so that only this connecting conductor 54 needs to be guided through the bushing
Fig. 3 zeigt eine Ausführungsvariante, bei der der Neigungswinkel der Leistungskabel 24 deutlich kleiner ist. Dementsprechend liegen hier die Schirmabgriffelemente 44 nahezu auf gleicher Höhe. Außerdem sind in diesem Beispiel für die elektrische Verbindung der Masseleiter (in Fig. 3 nicht gezeigt) mit den Schirmabgriffelementen 44 Ringkabelschuhe 56 anstelle der Anschlussstifte 48 vorgesehen. 3 shows an embodiment variant in which the angle of inclination of the power cables 24 is significantly smaller. Accordingly, the screen tapping elements 44 are almost at the same height here. In addition, ring cable lugs 56 are provided in this example for the electrical connection of the ground conductors (not shown in FIG. 3 ) to the shield tapping elements 44 instead of the connection pins 48 .
