Abstract
Description
Die Erfindung betrifft einen elektrischen Verbinder mit einer Entwässerungsvorrichtung zum Entwässern der Hohlräume des elektrischen Verbinders, sowie ein Gehäuse für diesen elektrischen Verbinder.The invention relates to an electrical connector with a dewatering device for dewatering the cavities of the electrical connector, and a housing for this electrical connector.
Die boomende Elektromobilität stellt die Kraftfahrzeughersteller vor neue Herausforderungen. Beispielsweise muss bei Elektrofahrzeugen eine Schnittstelle zum Laden der Fahrzeugbatterien vorgesehen werden. Landläufig wird diese Schnittstelle auch Ladebuchse genannt. Herkömmlicherweise wird zu diesem Zweck ein elektrischer Verbinder am Fahrzeug vorgesehen, der von der Außenseite zugänglich ist. Das abgestellte Fahrzeug kann mittels der Ladebuchse und einer Anschlussleitung mit der Ladestation verbunden werden. Wobei die Verbindungsleitung einen entsprechenden Ladestecker aufweist. Die Ladebuchse ist so angeordnet, dass der Ladestecker seitlich in die Karosserie eingesteckt wird, vergleichbar dem Betanken eines Fahrzeugs an einer Zapfvorrichtung. Da die Ladespannung für Elektrofahrzeuge wesentlich höher ist als die Bordspannung von Fahrzeugen mit Verbrennungsmotor, muss bei der Konstruktion von Ladesteckern und Ladebuchsen ein höherer Aufwand hinsichtlich der Isolationseigenschaften der verwendeten Komponenten betrieben werden. Um Unfälle durch Stromeinwirkung zu vermeiden, muss sichergestellt werden, dass Personen nicht mittels eines Elektrolyten (Wasser) mit der Ladespannung in Berührung kommen. Deshalb wird die Ladebuchse durch eine Abdeckung weitgehend gegen Berührung und Umwelteinflüsse geschützt. Es kann sich jedoch auch unter der Abdeckung Kondenswasser bilden oder Spritzwasser sammeln. Das Wasser sammelt sich z.B. in der Vertiefungen, die die Position des Ladesteckers in der Ladebuchse definiert oder in den Kontaktkammern, in denen sich die Kontaktelemente des Ladesteckers mit den Kontaktelementen der Ladebuchse treffen. Das Einstecken des Ladesteckers in eine mit Wasser gefüllte Ladebuchse kann dazu führen, dass ein Teil des Wassers unkontrolliert aus der Buchse herausspritzt und ein Teil in den Hohlräumen verbleibt. Beim Ladevorgang können dann Kriechströme auftreten, die die Funktion des Ladevorgangs beeinträchtigen. Es kann auch eine hohe Spannung an die Oberfläche des Ladesteckers gelangen und Personen gefährden. Langfristig können sich Ablagerungen in der Ladebuchse bilden und zu Fehlfunktionen beim Ladevorgang führen.The booming electromobility poses new challenges for motor vehicle manufacturers. For example, in electric vehicles, an interface for charging the vehicle batteries must be provided. This interface is also commonly called a charging socket. Conventionally, for this purpose, an electrical connector is provided on the vehicle, which is accessible from the outside. The parked vehicle can be connected by means of the charging socket and a connecting cable to the charging station. Wherein the connecting line has a corresponding charging plug. The charging socket is arranged so that the charging plug is inserted laterally into the body, similar to refueling a vehicle on a dispensing device. Since the charging voltage for electric vehicles is much higher than the on-board voltage of vehicles with internal combustion engine, in the design of charging plugs and charging sockets a higher effort in terms of the insulation properties of the components used must be operated. To avoid accidents due to the effect of electricity, it must be ensured that persons do not come into contact with the charging voltage by means of an electrolyte (water). Therefore, the charging socket is largely protected by a cover against contact and environmental influences. However, it may also form condensation under the cover or collect water spray. The water collects, for example, in the recesses, which defines the position of the charging plug in the charging socket or in the contact chambers, in which the contact elements of the charging plug meet with the contact elements of the charging socket. Inserting the charging plug into a charging socket filled with water can cause some of the water to splash out of the socket in an uncontrolled manner and leave a part in the cavities. During the charging process, leakage currents can occur which impair the function of the charging process. It can also be a high voltage to the Surface of the charging plug enter and endanger people. In the long term, deposits can form in the charging socket and lead to malfunctions during the charging process.
Um das Wasser aus dem elektrischen Verbinder herauszuleiten ist aus dem Stand der Technik eine Vorrichtung bekannt, die eine Dränage Öffnung an der Unterseite des elektrischen Verbinders vorsieht. Die Öffnung verläuft von der Aufnahmekontur (Vertiefungen die die Position des Ladesteckers definiert) durch die Seitenwand des Elektrischen Verbinders nach außen. Dadurch kann Wasser aus der Aufnahmekontur nach außen fließen. Diese Lösung hat allerdings den Nachteil, dass das Kondenswasser in den Hohlräumen, in denen sich die Kontaktelemente beim Einstecken des Ladesteckers mit den Kontaktelementen der Buchse treffen, nicht abfließen kann. Beim einstecken des Ladestecker wird vorhandenes Wasser nur teilweise aus den Kontaktkammern herausgedrückt wobei ein Rest in den Kontaktkammern verbleibt.In order to remove the water from the electrical connector, a device is known from the prior art, which provides a drainage opening at the bottom of the electrical connector. The opening extends from the receiving contour (recesses defining the position of the charging plug) through the side wall of the electrical connector to the outside. This allows water to flow out of the receiving contour to the outside. However, this solution has the disadvantage that the condensation in the cavities, in which meet the contact elements when inserting the charging plug with the contact elements of the socket, can not drain. When plugging in the charging plug existing water is only partially pushed out of the contact chambers leaving a residue in the contact chambers.
Es ist die Aufgabe der vorliegenden Erfindung, das oben erwähnte Problem zu überwinden und einen elektrischen Verbinder bereitzustellen bei dem sichergestellt ist, dass auftretende Wasser aus den Hohlräumen nach außerhalb des elektrischen Verbinders geleitet wird.It is the object of the present invention to overcome the above-mentioned problem and to provide an electrical connector in which it is ensured that occurring water is led out of the cavities to the outside of the electrical connector.
Die beanspruchte Erfindung löst diese Aufgabe durch ein Gehäuse mit den Merkmalen des Anspruch 1 und insbesondere dadurch, dass sich ein Ablaufkanal von der Bohrung durch die Rückwand des Gehäuses zur äußeren Oberfläche erstreckt, wobei in die äußere Oberfläche der Rückwand eine Entwässerungsnut geformt ist, die sich vom Ablaufkanal erstreckt und einen Fließpfad für ein Fluid zur Drainageöffnung bereitstellt.The claimed invention achieves this object by a housing with the features of
Sowie durch einen elektrischen Verbinder nach Anspruch 7 und insbesondere dadurch, das sich ein Ablaufkanal von der der Bohrung durch die Rückwand des Gehäuses zur äußeren Oberfläche erstreckt, wobei in die äußere Oberfläche der Rückwand eine Entwässerungsnut geformt ist, die sich vom Ablaufkanal erstreckt und einen Fließpfad für ein Fluid zur Drainageöffnung bereitstellt und eine Lage Dichtungsmaterial, die die äußere Oberfläche der Rückseite und die Entwässerungsnut abdeckt und eine Sicherungskappe am Gehäuse befestigbar, die das Dichtungsmaterial an der Rückseite hält.As well as an electrical connector according to claim 7 and in particular in that a drainage channel extends from the bore through the rear wall of the housing to the outer surface, wherein in the outer surface of the rear wall is formed a drainage groove extending from the drainage channel and providing a flow path for a fluid to the drainage opening and a layer of sealant covering the outer surface of the backside and the drainage groove and a safety cap attachable to the housing holding the sealant material at the backside.
Bei dem erfindungsgemäßen Gehäuse wird Wasser, das sich in der Bohrungen des Gehäuses niederschlägt oder Spritzwasser das ins Gehäuse gelangt, durch ein System von einem Kanal und einer Nut, kontrolliert zu einer Ablauföffnung geleitet. Von der Ablauföffnung kann das Wasser dann durch einen Schlauch oder ein Rohr nach außerhalb des Fahrzeugs geleitet werden. Das Kanalsystem verhindert generell ein Ansammeln von Wasser in der Kontaktkammer so dass sich keine Korrosion an dem elektrischen Kontaktelement bilden kann.In the housing according to the invention, water which precipitates in the bores of the housing or splashing water which enters the housing is passed through a system of a channel and a groove, controlled to a drain opening. From the drain opening, the water can then be passed through a hose or a pipe to the outside of the vehicle. The channel system generally prevents accumulation of water in the contact chamber so that no corrosion can form on the electrical contact element.
Mit einer Lage Dichtungsmaterial auf der Rückseite des erfindungsmäßigen Steckverbinders, werden die Nut und das Kontaktelement gedichtet. Die Lage Dichtungsmaterial deckt die rückseitige Oberfläche des Stecker Gehäuses ab, wodurch die offene Seite der Ablaufnut geschlossen wird und das Wasser nun in einem rohrförmigen Gebilden in Richtung der Drainageöffnung geführt wird. Das elektrische Kontaktelement tritt aus der Rückseite des Gehäuses und durch die Lage Dichtungsmaterial. Das Dichtungsmaterial schmiegt sich umfänglich um das Kontaktelement und dichtet so den Anschlussbereich des Kontaktelements gegen die Rückseite des Gehäuses. So wird erreicht, dass der Bereich, in dem die Kontaktelemente mit den elektrischen Leitungen verbunden werden, trocken bleibt. Eine Sicherungskappe hält das Dichtungsmaterial in seiner Position und übt einen leichten Druck auf das Dichtungsmaterial aus, wodurch die Dichtwirkung verbessert wird.With a layer of sealing material on the back of the inventive connector, the groove and the contact element are sealed. The layer of sealing material covers the back surface of the plug housing, whereby the open side of the drainage groove is closed and the water is now guided in a tubular formation in the direction of the drainage opening. The electrical contact element emerges from the back of the housing and through the layer of sealing material. The sealing material wraps circumferentially around the contact element and thus seals the connection region of the contact element against the rear side of the housing. This ensures that the area in which the contact elements are connected to the electrical lines remains dry. A safety cap holds the sealing material in place and exerts a slight pressure on the sealing material, thereby improving the sealing effect.
