Description

Ladekabelseitiges Steckerteil einer elektrischen Steckvorrichtung eines  Charging cable-side plug part of an electrical plug-in device of a
Fahrzeugs  vehicle
Die Erfindung betrifft ein ladekabelseitiges Steckerteil einer elektrischen Steckvorrichtung eines Fahrzeugs, insbesondere eines Personenkraftwagens, zum An- schluss eines elektrischen Ladekabels an ein an dem Fahrzeug vorgesehenes Buchsenteil, mit mindestens einem in dem Steckergehäuse angeordneten Hoch- Stromkontakt, der bei in das Buchsenteil eingestecktem Steckerteil zwischen einer zurückgezogenen ersten Position, in der er von einem im Buchsenteil vorgesehenen, stiftförmigen Gegenkontakt elektrisch getrennt ist, und einer vorgeschobenen zweiten Position, in der er mit dem Gegenkontakt elektrisch verbunden ist, verlagerbar angeordnet ist. The invention relates to a charging cable-side plug part of an electrical plug-in device of a vehicle, in particular a passenger car, for connection of an electrical charging cable to a provided on the vehicle socket part, with at least one arranged in the plug housing high-current contact, the plugged in in the socket part between a retracted first position in which it is electrically separated from a provided in the socket part, pin-shaped mating contact, and a second advanced position in which it is electrically connected to the mating contact, displaceably arranged.
Entscheidend für die Verbreitung von elektrisch betriebenen Fahrzeugen, insbesondere von Personen- und Lastkraftwagen ist der Aufbau einer Ladeinfrastruktur, die ein schnelles Laden des Fahrzeugakkumulators auch unterwegs, ähnlich einem Tankvorgang bei Fahrzeugen mit Verbrennungsmotoren, ermöglicht. Decisive for the spread of electrically operated vehicles, in particular of passenger cars and trucks is the construction of a charging infrastructure, which enables fast charging of the vehicle battery on the way, similar to a refueling process in vehicles with internal combustion engines.
Hierzu sind nicht nur Akkumulatoren notwendig, die mit sehr hohen Strömen von derzeit bis zu 200 A bei einer Spannung von bis zu 500 V geladen werden können, sondern auch elektrische Steckvorrichtungen, die die sichere Übertragung einer derartigen elektrischen Leistung ermöglichen. For this purpose, not only batteries are required, which can be charged with very high currents of currently up to 200 A at a voltage of up to 500 V, but also electrical plug-in devices that allow the secure transmission of such electrical power.
Insbesondere die ladekabelseitigen Steckerteile müssen daher hohen technischen Anforderungen genügen. Denn neben einer Aufsteckbarkeit auf das fahrzeugseiti- ge Buchsenteil, die ähnlich einfach erfolgen muss, wie das Einführen des Zapfventils in die Tanköffnung eines verbrennungsmotor-betriebenen Fahrzeugs, müssen elektrische Leistungen in der vorstehend erwähnten Höhe als Gleichstrom übertragen werden, da Gleichrichter, die für derartige Leistungen in Betracht kommen, aufwendig und voluminös sind, so dass ein Einbau solcher in ein Fahrzeug nicht wünschenswert ist. In particular, the charging cable side connector parts must therefore meet high technical requirements. Because in addition to being attachable to the vehicle side ge socket part, which must be done similarly simple as the insertion of the nozzle in the tank opening of an internal combustion engine-powered vehicle, electrical power in the above-mentioned level must be transmitted as DC, since rectifiers that come into consideration for such services, consuming and bulky are so that installation of such in a vehicle is not desirable.
Der Erfindung liegt daher die Aufgabe zugrunde, ein ladekabelseitiges Steckerteil einer elektrischen Steckverbindung eines Fahrzeugs zu schaffen, welches zur Er- füllung der vorstehend erläuterten Anforderungen geeignet ist. The invention is therefore based on the object to provide a charging cable-side plug part of an electrical connector of a vehicle, which is suitable for fulfilling the requirements explained above.
Diese Aufgabe wird durch das in Anspruch 1 wiedergegebene ladekabelseitige Steckerteil gelöst. Bei diesem Steckerteil umfasst zumindest einer, vorzugsweise umfassen sämtliche Hochstromkontakte, die im Regelfall dem Anschluss des Gleichspannungsladestroms dienen, einen mit einer Ader des Ladekabels verbundenen Stiftkontaktteil und einen Hülsenkontaktteil. Der Hülsenkontaktteil ist mit dem Stiftkontaktteil elektrisch verbunden. Er weist einen freien, an den Gegenkontakt derart ange- passten Endbereich auf, so dass der Endbereich unter elektrischer Kontaktierung auf den am Fahrzeug befindlichen Gegenkontakt aufschiebbar ist. Da der Hülsenkontaktteil darüber hinaus einen Verschiebbereich umfasst, der derart ausgestaltet ist, dass der Hülsenkontaktteil unter Belassung seiner elektrischen Verbindung mit dem Stiftkontaktteil zwischen der ersten Position, in der er von dem im Buchsenteil vorgesehenen Gegenkontakt elektrisch getrennt ist, und der zweiten Position, in der er mit dem Gegenkontakt elektrisch verbunden ist, verlagerbar angeordnet ist, kann die mechanische Verbindung zwischen dem ladekabelseitigen Steckerteil und dem fahrzeugseitigen Buchsenteil vollständig bewerkstelligt werden, bevor die elektrische Verbindung hergestellt wird. Letztere wird anschließend dadurch er- zeugt, dass lediglich das Hülsenkontaktteil, welches durch geeignete Maßnahmen manuell von außen oder auch motorisch mit Hilfe einer in dem Steckerteil integrierten Einrichtung von der ersten in die zweite Position verlagert wird. Nach Beendigung des Ladevorganges erfolgt dann in umgekehrter Reihenfolge zunächst die elektrische, dann die mechanische Trennung des ladekabelseitigen Steckerteils vom fahrzeugseitigen Buchsenteil. This object is achieved by the reproduced in claim 1 charging cable side connector part. In this connector part includes at least one, preferably include all high-current contacts, which are usually the connection of the DC charging current, connected to a wire of the charging cable pin contact part and a sleeve contact part. The sleeve contact part is electrically connected to the pin contact part. It has a free end region adapted to the mating contact, so that the end region can be pushed onto the mating contact provided on the vehicle while making electrical contact. Moreover, since the sleeve contact portion comprises a sliding portion configured such that the sleeve contact portion is electrically disengaged from the first position in which it is electrically separated from the mating contact provided in the female portion, leaving its electrical connection with the pin contact portion, and the second position it is electrically connected to the mating contact, is arranged to be displaceable, the mechanical connection between the charging cable-side plug part and the vehicle-side socket part can be completely accomplished before the electrical connection is made. The latter is subsequently produced by merely displacing the sleeve contact part, which is moved from the first to the second position manually by suitable measures from the outside or else by motor means with the aid of a device integrated in the plug part. After completion of the charging process is then in the reverse order first the electrical, then the mechanical separation of the charging cable-side connector part from the vehicle-side socket part.
Ein wesentlicher Vorteil des erfindungsgemäßen Steckerteils ist es, dass das Stift- kontaktteil, mit welchem eine Ader des Ladekabels verbunden ist, relativ zum Steckergehäuse nicht verschoben wird. Das Ladekabel und das Stiftkontaktteil können dadurch fest mit dem Steckergehäuse verbunden sein, beispielsweise durch Umspritzen von Kabel- und Stiftkontaktteilenden mit dem isolierenden Kunststoffmaterial des Steckergehäuses, so dass eine stabile, dauerhafte und damit be- triebssichere Lösung erreicht wird. A significant advantage of the plug part according to the invention is that the pin contact part, with which a wire of the charging cable is connected, is not displaced relative to the plug housing. The charging cable and the pin contact part can thereby be firmly connected to the plug housing, for example by encapsulation of cable and pin contact part ends with the insulating plastic material of the plug housing, so that a stable, durable and thus operationally safe solution is achieved.
Bei einer bevorzugten Ausführungsform weist der Verschiebbereich des Hülsen- kontaktteils einen etwa kreisrunden Innenquerschnitt und der Stiftkontaktteil einen etwa kreisrunden Außenquerschnitt auf. Durch diese Ausgestaltung sind sowohl Hülsenkontaktteil, als auch Stiftkontaktteil mit vergleichsweise geringem Aufwand herstellbar. In a preferred embodiment, the displacement region of the sleeve contact part has an approximately circular inner cross section and the pin contact part has an approximately circular outer cross section. As a result of this configuration, both the sleeve contact part and the pin contact part can be produced with comparatively little effort.
Zur Reduzierung der zum Verschieben des Hülsenkontaktteils benötigten Betätigungskraft sind die Radien der Innen- und Außenquerschnitte vorzugsweise derart bemessen, dass zwischen beiden ein Ringspalt verbleibt, in dem mindestens ein die elektrische Verbindung zwischen dem Hülsen- und dem Stiftkontaktteil bewirkendes Kontaktelement angeordnet ist. Bei diesem Kontaktelement kann es sich beispielsweise um ein solches handeln, welches bei ausreichender elektrischer Leitfähigkeit die Gleitreibung zwischen dem Hülsenkontaktteil und dem Stiftkon- taktteil reduziert. In order to reduce the actuation force required for displacing the sleeve contact part, the radii of the inner and outer cross sections are preferably dimensioned such that an annular gap remains between them, in which at least one contact element effecting the electrical connection between the sleeve contact part and the pin contact part is arranged. This contact element may, for example, be one which, with sufficient electrical conductivity, reduces the sliding friction between the sleeve contact part and the pin contact part.
Besonders bevorzugt ist es jedoch, wenn das Kontaktelement eine zu einem Ring geformte Spiralfeder aus einem eine ausreichende elektrische Leitfähigkeit aufweisenden Material umfasst. Diese im folgenden auch„Ring-Spiralfeder" genann- ten Kontaktelemente können derart ausgebildet sein, dass der Ringinnendurchmesser in noch nicht auf das Stiftkontaktteil aufgeschobenen Zustand geringfügig kleiner ist als der Au ßendurchmesser des Stiftkontaktteils, so dass die Ring- Spiralfeder im aufgeschobenen Zustand unter einer elastischen Kraft an dem Stift- kontaktteil anliegt. Eine wirkungsvolle elektrische Kontaktierung wird hierdurch sichergestellt. However, it is particularly preferred if the contact element comprises a ring-shaped coil spring made of a material having sufficient electrical conductivity. These contact elements, also referred to below as "ring spiral springs", can be configured in such a way that the ring inner diameter is slightly smaller than the outer diameter of the pin contact part in the state not yet pushed onto the pin contact part, so that the ring spiral spring is in the pushed state under a elastic force on the pin contact part is present. An effective electrical contact is thereby ensured.
Darüber hinaus weist die Ring-Spiralfeder einen Spiraldurchmesser auf, so dass der Außendurchmesser des Rings im auf das Steckkontaktteil aufgeschobenen Zustand geringfügig größer als der Innendurchmesser des Verschiebebereichs des Hülsenkontaktteils ist. Beim Aufschieben des Verschiebebereichs des Hül- senkontaktteils wird die Ring-Spiralfeder verformt, so dass sie auch unter einer elastischen Kraft an dem Hülsenkontaktteil anliegt und auch hier eine zuverlässige elektrische Kontaktierung sichergestellt ist. Beim Verschieben des Hülsenkontaktteils auf dem Stiftkontaktteil kann die Spiralfeder für den Fall, dass sie nicht beispielsweise durch eine Lagerung in einer Nut entweder gegenüber dem Stiftkontaktteil, oder gegenüber dem Verschiebebereich des Hülsenkontaktteils fixiert ist, eine Abrollbewegung vollziehen, wodurch die für die Verschiebebewegung benö- tigte Kraft verringert und ein abriebbedingter Verschleiß reduziert ist. In addition, the ring spiral spring has a spiral diameter, so that the outer diameter of the ring in the pushed onto the plug contact part state is slightly larger than the inner diameter of the sliding portion of the sleeve contact part. When the sliding region of the sleeve contact part is slid on, the annular spiral spring is deformed, so that it also bears against the sleeve contact part under an elastic force and reliable electrical contacting is ensured here as well. When moving the sleeve contact part on the pin contact part, the coil spring in the event that it is not fixed, for example, by a bearing in a groove either opposite the pin contact part, or with respect to the sliding portion of the sleeve contact part, perform a rolling movement, whereby the neces sary for the sliding movement Reduced force and abrasion-related wear is reduced.
Der freie Endbereich, der bei mechanisch auf das fahrzeugseitige Buchsenteil aufgestecktem Steckerteil wahlweise mit den im Buchsenteil vorgesehenen Gegenkontakten in elektrische Verbindung gebracht werden kann, ist vorzugsweise tulpenkontaktförmig mit durch Schlitze voneinander getrennten Kontaktlaschen ausgebildet. Aufgrund dieser Ausgestaltung kann der im Buchsenteil vorgesehene Gegenkontakt besonders einfach und daher preisgünstig als einfacher Stiftkontakt vorzugsweise mit einem konischen, ein Aufschieben des tulpenkontaktförmigen Endbereichs erleichternden freien Endes ausgebildet sein. Die Kontaktlaschen können dabei derart geformt sein und aus einem Material bestehen, dass ihre Innenseiten im auf einen Gegenkontakt aufgeschobenen Zustand im Wesentlichen flächig mit diesem zusammenwirken. The free end region, which can be brought into electrical connection with mechanically attached to the vehicle-mounted socket part connector part with the mating contacts provided in the socket part, is preferably tulpenkontaktförmig formed with slots separated from each other by contact tabs. Due to this configuration, the mating contact provided in the socket part can be designed to be particularly simple and therefore cost-effective as a simple pin contact, preferably with a conical free end which facilitates the sliding of the tulip-contact-shaped end region. In this case, the contact tabs can be shaped in such a way and consist of a material such that their inner sides essentially interact with the latter in a state pushed onto a mating contact.
Um die elektrische Kontaktierung auch nach einem vielfachen Aufschiebe- und Trennvorgang weiterhin sicherzustellen, können die Kontaktlaschen außen von einem Federelement umgeben sein, welches den Andruck an den Gegenkontakt erhöht. Das Stiftkontaktteil kann grundsätzlich in beliebiger Weise mit der zugehörigen Ader des Ladekabels verbunden sein. Besonders bevorzugt ist es jedoch, hierfür eine Crimp-Verbindung vorzusehen, da diese gleichermaßen eine zuverlässige mechanische und elektrische Verbindung sicherstellt sowie unempfindlich gegen wechselnde mechanische Belastungen und hohe Temperaturen ist. In order to continue to ensure the electrical contact even after a multiple Aufschiebe- and separation process, the contact tabs may be surrounded by a spring element outside, which increases the pressure on the mating contact. The pin contact part can in principle be connected in any way with the associated wire of the charging cable. However, it is particularly preferred to provide a crimp connection for this purpose, since this equally ensures a reliable mechanical and electrical connection and is insensitive to changing mechanical loads and high temperatures.
Schließlich kann der Steckerteil weitere elektrische Kontakte zur Herstellung einer Wechselstrom- und/oder Signalübertragung zwischen dem Fahrzeug und einer Ladestation umfassen. Eine derartige Ausgestaltung ist für elektrisch betriebene Fahrzeuge vorgesehen, die zusätzlich über eine fahrzeuginterne Gleichrichteranordnung verfügen, die die übliche Netz-Wechselspannung von beispielsweise 220 V mit einer maximalen Stromstärke von 16 A in einen zum Laden des Akkumulators des Fahrzeugs geeigneten Ladestrom umformt. Mit Hilfe dieses Ladestroms kann der Akkumulator dann ebenfalls geladen werden, wobei jedoch erheblich längere Ladezeiten erforderlich sind. Dieser Anschluss ist daher für ein Laden während der Nichtbenutzung des Fahrzeugs, beispielsweise während dessen Standzeiten in einer Garage, vorgesehen. Darüber hinaus können diese oder auch weitere, separate Kontakte, die bereits nach dem mechanischen Einsteckvorgang des ladekabelseitigen Steckerteils in das fahrzeugseitige Buchsenteil zu einer elektrischen Kontaktierung führen, zu einer Signalübertragung zwischen dem Fahrzeug und der Ladestation Verwendung finden. Diese kann beispielsweise dazu dienen, der Ladestation eine ordnungsgemäße mechanische Verbindung zu melden, bevor die Hülsenkontakte zur Verlagerung von der ersten in die zweite Position freigegeben oder motorisch verlagert werden. Finally, the plug part can comprise further electrical contacts for producing an AC and / or signal transmission between the vehicle and a charging station. Such an embodiment is provided for electrically powered vehicles, which additionally have an in-vehicle rectifier arrangement, which converts the usual mains AC voltage of, for example, 220 V with a maximum current of 16 A in a charging current suitable for charging the battery of the vehicle. With the help of this charging current, the accumulator can then also be charged, but considerably longer charging times are required. This connection is therefore intended for charging during non-use of the vehicle, for example during its service life in a garage. In addition, these or other, separate contacts, which already lead after the mechanical insertion of the charging cable-side connector part in the vehicle-mounted socket part to an electrical contact, find a signal transmission between the vehicle and the charging station use. This can serve, for example, to notify the charging station of a proper mechanical connection before the sleeve contacts are released for displacement from the first to the second position or moved by a motor.

Das Gehäuse umfasst ferner eine Verriegelungseinrichtung 1 1 , mit welcher ein auf ein fahrzeugseitiges Buchsenteil 12, in Fig. 3 dargestellt, aufgeschobenes Steckerteil 100 gegen ein unbeabsichtigtes Trennen gesichert werden kann. The housing further comprises a locking device 1 1, with which a on a vehicle-side socket part 12, shown in Fig. 3, pushed-plug part 100 can be secured against inadvertent disconnection.
Ferner ist in dem Gehäuse 1 eine Verlagerungseinrichtung 13 vorgesehen, die der Verlagerung der Hochstromkontakte 2, 3 zwischen einer zurückgezogenen ersten Position, in der sie bei in das Buchsenteil 12 eingestecktem Steckerteil 100 von im Buchsenteil 12 vorgesehenen Gegenkontakten 14, 15 elektrisch getrennt sind, und einer vorgeschobenen zweiten Position, in der sie mit den Gegenkontakten 14, 15 elektrisch verbunden sind, verlagert werden können. Die Verlagerungseinrichtung 13 umfasst eine Handhabe 16, mittels welcher über ein Zahnstangenge- triebe 17 ein mit den Hochstromkontakten 2, 3 mechanisch verbundenes Schiebestück 1 8, welches lediglich in Fig. 4 bis 6 schematisch dargestellt ist, betätigt werden kann. Wie in Fig. 4 bis 6 erkennbar ist, welche schematisch die Ausgestaltung der Hochstromkontakte 2, 3 am Beispiel des Hochstromkontakts 2 und des Gegenkontakts 15 in verschiedenen Steckerteilpositionen und Betriebszuständen zeigen, umfasst der Hochstromkontakt 2 einen Stiftkontaktteil 19, welcher mit einer Ader 20 eines Ladekabels m it Hilfe einer Crimp-Verbindung 21 mechanisch und elektrisch ver- bunden ist. Auf dem Stiftkontaktteil 19 ist ein Hülsenkontaktteil 22 in Richtung des Pfeils P mit seinem Verschiebebereich 23 verlagerbar angeordnet. Das Stiftkontaktteil 19 weist einen kreisrunden Außenquerschnitt, der Verschiebebereich 23 des Hülsenkontaktteils 22 einen kreisrunden Innenquerschnitt auf. Die Querschnitte sind derart bemessen, dass zwischen dem Stiftkontaktteil 1 9 und dem Ver- schiebebereich 23 ein Ringspalt 24 verbleibt. In dem Ringspalt 24 ist eine zu einem Ring geformte Spiralfeder 25 (Fig. 7) aus einem elektrisch leitenden Material vorgesehen, welche elastisch sowohl an dem Außenumfang 26 des Stiftkontaktteils 1 9, als auch am Innenumfang 27 des Verschiebebereichs 23 anliegt. Diese Ring-Spiralfeder 25 bildet ein Kontaktelement 32, welches der elektrischen Ver- bindung des Stiftkontaktteils 19 mit dem Hülsenkontaktteil 22 dient. Furthermore, a displacement device 13 is provided in the housing 1, which are the displacement of the high-current contacts 2, 3 between a retracted first position in which they are electrically separated when plugged into the socket 12 plug part 100 provided in the female part 12 mating contacts 14, 15, and an advanced second position in which they are electrically connected to the mating contacts 14, 15, can be moved. The displacement device 13 comprises a handle 16, by means of which a toothed rack 17 a 17 with the high current contacts 2, mechanically connected sliding piece 1 8, which is shown only schematically in Fig. 4 to 6, can be operated. As can be seen in FIGS. 4 to 6, which schematically show the configuration of the high-current contacts 2, 3 using the example of the high-current contact 2 and the mating contact 15 in different plug-part positions and operating states, the high-current contact 2 comprises a pin contact part 19 which is connected to a wire 20 of a charging cable With the aid of a crimp connection 21 is mechanically and electrically connected. On the pin contact part 19, a sleeve contact part 22 in the direction of the arrow P is arranged with its displacement region 23 displaced. The pin contact part 19 has a circular outer cross section, the displacement region 23 of the sleeve contact part 22 has a circular inner cross section. The cross sections are dimensioned such that an annular gap 24 remains between the pin contact part 1 9 and the displacement area 23. In the annular gap 24 is formed into a ring-shaped coil spring 25 (Fig. 7) made of an electrically conductive material, which rests elastically on both the outer circumference 26 of the pin contact part 1 9, and on the inner circumference 27 of the sliding portion 23. This ring spiral spring 25 forms a contact element 32 which serves for the electrical connection of the pin contact part 19 with the sleeve contact part 22.
Ferner weist das Hülsenkontaktteil 22 einen auf den Gegenkontakt 15 aufschiebbaren freien Endbereich 28 auf, welcher tulpenkontaktförmig mit durch Schlitze 29 voneinander getrennten Kontaktlaschen 30 ausgebildet ist. Die Kontaktlaschen 30 sind im Bereich des freien Endes von einem Federelement 31 umgeben. Furthermore, the sleeve contact part 22 has a free end region 28 which can be pushed onto the mating contact 15 and which is designed in a tulip contact shape with contact lugs 30 separated from one another by slots 29. The contact tabs 30 are surrounded by a spring element 31 in the region of the free end.
Nachdem das Steckerteil 100 mechanisch mit dem Buchsenteil 12 verbunden worden ist, befindet sich zunächst das Hülsenkontaktteil 22 in seiner ersten, zurückgezogenen Position, die in Fig. 5 schematisch dargestellt ist. Aus dieser Posi- tion kann mit Hilfe des Schiebestücks 18 das Hülsenkontaktteil 22 gemäß Pfeil P1 auf den Gegenkontakt 15 aufgeschoben werden, bis es die in Fig. 6 dargestellte, zweite Position, in welcher das Hülsenkontaktteil 22 den Gegenkontakt 15 teilweise umgibt und die Kontaktlaschen 13 unter einer elastischen Kraft an dem Gegenkontakt 15 anliegen, verschoben werden. Bevor eine mechanische Trennung des Steckerteils 100 von dem Buchsenteil 12 erfolgt, kann das Hülsenkontaktteil durch Verlagerung in Richtung des Pfeiles P2 elektrisch von dem Gegenkontakt 15 getrennt werden. After the plug part 100 has been mechanically connected to the socket part 12, the sleeve contact part 22 is initially in its first retracted position, which is shown schematically in FIG. From this position, with the aid of the sliding piece 18, the sleeve contact part 22 can be slid onto the mating contact 15 according to arrow P1 until the second position shown in FIG. 6 in which the sleeve contact part 22 partially surrounds the mating contact 15 and the contact lugs 13 are applied under an elastic force to the mating contact 15, to be moved. Before a mechanical separation of the plug part 100 takes place from the socket part 12, the sleeve contact part can be electrically separated from the mating contact 15 by displacement in the direction of the arrow P2.
