Description

Adapter für elektrische Steckverbindungen an Brennstoffeinspritzventilen Adapters for electrical connectors on fuel injectors
Stand der TechnikState of the art
Die Erfindung geht aus von einem Adapter für elektrische Steckverbindungen an Brennstoffeinspritzventilen nach der Gattung des Hauptanspruchs .The invention relates to an adapter for electrical connectors on fuel injectors according to the preamble of the main claim.
Die elektrische Kontaktierung zwischen einem Aktor eines Brennstoffeinspritzventils und der Spannungsquelle erfolgt gewöhnlich über ein Steckanschlußsystem, bei welchem der Stecker so geformt ist, daß er formschlüssig in den Steckanschluß am Brennstoffeinspritzventil einsteckbar ist. Der Stecker und der Steckanschluß sind dabei mittels Spritzguß aus Kunststoff herstellbar. Die Steckverbindung sollte außerdem so beschaffen sein, daß die elektrischen Kontakte gegenüber der Umgebung zum Schutz gegen Korrosion abgedichtet sind, um nachfolgenden Kontak schwächen entgegenzuwirken.The electrical contact between an actuator of a fuel injector and the voltage source usually takes place via a plug connection system, in which the plug is shaped such that it can be positively inserted into the plug connection on the fuel injector. The plug and the plug connection can be produced by injection molding from plastic. The connector should also be such that the electrical contacts are sealed from the environment to protect against corrosion to counteract subsequent contact weaknesses.
Nachteilig bei bekannten SteckverbindungsSystemen ist insbesondere der hohe Fertigungsaufwand, der anfällt, wenn Änderungen am Stecker- oder am Steckanschluß des Brennstoffeinspritzventils umgesetzt werden müssen. So können beispielsweise die Anforderungen verschiedener Kunden bedingt durch kundenspezifisch unterschiedlich geformte Stecker nur mittels vfcj-o uiedener Spritzwerkzeuge sowie umfangreicher Montage und Demontage der Werkzeuge, was zu langen Rüstzeiten führt, realisiert werden.A disadvantage of known plug-in connection systems is, in particular, the high production expenditure which arises when changes to the plug or plug connection of the fuel injector have to be implemented. For example, the requirements of different customers can be caused by customer-specific shapes Plugs can only be realized using vfcj-o uieden injection molds as well as extensive assembly and disassembly of the molds, which leads to long set-up times.
Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Adapter für elektrische Steckverbindungen für ein Brennstoffeinspritzventil mit den Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß Änderungen in der Form des Gegensteckers nur Änderungen in der Form des Adapters, edoch nicht in der Form des Steckanschlusses des Brennstoffeinspritzventils erfordern, welche leicht umsetzbar und damit schnell und kostengünstig realisierbar sind.The adapter according to the invention for electrical plug connections for a fuel injector with the features of the main claim has the advantage that changes in the shape of the mating connector only require changes in the shape of the adapter, but not in the form of the plug connection of the fuel injector, which are easy to implement and therefore can be implemented quickly and inexpensively.
Zudem zeichnet sich der Adapter durch eine zuverlässige Abdichtung der elektrischen Kontakte gegenüber der Umgebung aus.In addition, the adapter is characterized by a reliable seal of the electrical contacts from the environment.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterentwicklungen und Verbesserungen des im Hauptanspruch angegebenen Adapters möglich.Advantageous further developments and improvements of the adapter specified in the main claim are possible through the measures listed in the subclaims.
Von Vorteil ist auch, daß die Dichtungen zwischen dem Gegenstecker und dem Adapter bzw. zwischen dem Adapter und dem Steckanschluß des Brennstoffeinspritzventils variabel als radiale oder axiale Dichtungen je nach den an die Steckverbindung gestellten Anforderungen ausführbar sind.It is also advantageous that the seals between the mating connector and the adapter or between the adapter and the plug connection of the fuel injector can be designed variably as radial or axial seals depending on the requirements placed on the plug connection.
Die elastischen Federzungen an den Enden der Kontaktfahnen des Adapters, des Gegensteckers und/oder des Steckanschlusses stellen eine sichere Kontaktierung sowie einen Schutz gegen willkürliches Lösen der Steckverbindung durch Klemmwirkung sicher.The elastic spring tongues at the ends of the contact lugs of the adapter, the mating connector and / or the plug connection ensure reliable contacting and protection against arbitrary loosening of the plug connection by clamping action.
Vorteilhafterweise ist der Adapter durch einen Federbügel am Steckanschluß des Brennstoffeinspritzventils gesichert, wodurch eine leichtere Verbindbarkeit mit dem Gegenstecker der elektrischen Leitung erzielt werden kann. ZeichnungThe adapter is advantageously secured by a spring clip on the plug connection of the fuel injector, as a result of which an easier connection to the mating connector of the electrical line can be achieved. drawing

B. leads to an electronic control unit, not shown. The mating connector 6 can be connected to the fuel injector via the adapter 1 and allows electrical contacting to actuate the fuel injector.
Der Adapter 1 ist dabei in Form eines rund- oder ovalzylindrischen Körpers 9 ausgebildet, der mit einem ersten Ende 3 auf den Steckanschluß 4 des Brennstoffeinspritzventils aufsteckbar und mit einem zweiten Ende 5 in den Gegenstecker 6 der elektrischen Leitung einsteckbar ist .The adapter 1 is in the form of a round or oval cylindrical body 9, which can be plugged with a first end 3 onto the plug connection 4 of the fuel injector and with a second end 5 into the mating connector 6 of the electrical line.
Der Steckanschluß 4 des Brennstoffeinspritzventils ist dabei in Form einer Hülse 15 ausgebildet, die vorzugsweise aus Kunststoff besteht und beim Umspritzen des Brennstoffeinspritzventils mit angespritzt wird. Dabei überragt die Hülse 15 die zur Kontaktierung benötigten Kontaktfahnen 14, .welche beispielsweise mit einem nicht näher dargestellten Aktor des Brennstoffeinspritzventils in Verbindung stehen. Die Hülse 15 ist nach Aufstecken des Adapters 1 auf den Steckanschluß 4 in eine Ausnehmung 16 des Adapters 1 eingeschoben, in welcher eine erste Dichtung 7 an einem Ausnehmungsgrund 19 der Ausnehmung 16 angeordnet ist, die im vorliegenden Ausführungsbeispiel als axiale Dichtung 7 ausgeführt ist. Die Hülse 15 liegt dabei in dichtender Anlage an der ersten Dichtung 7 an, so daß die Kontaktfahnen 14 des Steckanschlusses 4 gegen die Umgebung abgedichtet sind.The plug connection 4 of the fuel injector is designed in the form of a sleeve 15, which is preferably made of plastic and is also molded on when the fuel injector is overmolded. The sleeve 15 projects beyond those required for contacting Contact lugs 14, which are connected, for example, to an actuator of the fuel injector, not shown. After plugging the adapter 1 onto the plug connection 4, the sleeve 15 is pushed into a recess 16 of the adapter 1, in which a first seal 7 is arranged on a recess base 19 of the recess 16, which in the present exemplary embodiment is designed as an axial seal 7. The sleeve 15 is in sealing contact with the first seal 7, so that the contact tabs 14 of the connector 4 are sealed against the environment.
Die Kontaktfahnen 14 des Steckanschlusses 4 sind im bevorzugten Ausführungsbeispiel nebeneinander angeordnet und stehen mit Kontaktfahnen 10 des Adapters 1 über an den Kontaktfahnen 10 oder 14 ausgebildete elastische Federlaschen 12 in elektrisch leitender Verbindung. Die elastischen Federlaschen 12 sind in Fig. 2 zur Verdeutlichung in einer Schnittansicht dargestellt und näher beschrieben.In the preferred exemplary embodiment, the contact lugs 14 of the plug connection 4 are arranged next to one another and are in electrically conductive connection with contact lugs 10 of the adapter 1 via elastic spring tabs 12 formed on the contact lugs 10 or 14. The elastic spring tabs 12 are shown in FIG. 2 for clarification in a sectional view and described in more detail.
In einem zweiten Ende 5 des Adapters 1 ist der Gegenstecker 6 der elektrischen Leitung eingesteckt. Bei dem in Fig. 1 dargestellten Gegenstecker 6 handelt es sich um einen sogenannten AKD-Stecker, der ebenfalls zwei Kontaktfahrten 13 aufweist. Die Kontaktfahnen 13 können dabei ebenfalls mittels elastischer Federlaschen 12, die entweder an den Kontaktfahnen 13 des Gegensteckers 6 oder an den Kontaktfahnen 10 des Adapters 1 ausgebildet sein können, leitend miteinander verbunden werden. Im vorliegenden Ausführungsbeispiel sind die Federlaschen 12 an den Kontaktfahnen 13 des Gegensteckers 6 ausgebildet.The mating connector 6 of the electrical line is inserted into a second end 5 of the adapter 1. The mating connector 6 shown in FIG. 1 is a so-called AKD connector, which also has two contact runs 13. The contact tabs 13 can also be conductively connected to one another by means of elastic spring tabs 12, which can either be formed on the contact tabs 13 of the mating connector 6 or on the contact tabs 10 of the adapter 1. In the present embodiment, the spring tabs 12 are formed on the contact tabs 13 of the mating connector 6.
Der Adapter 1 weist an seinem zweiten Ende 5 eine Hülse 17 auf, die sich in eine Ausnehmung 18 des Gegensteckers 6 erstreckt . Zwischen den Kontaktf hnen 13 des Gegensteckers 6 und der Hülse 17 des Adapters 1 ist eine zweite Dichtung 8 angeordnet, die die Kontaktfahnen 13 des Gegensteckers 6 gegen die Umgebung abdichtet . Die zweite Dichtung 8 ist dabei als radiale Dichtung ^ in Form eines Wellenrings bzw. einer Labyrinthdichtung ausgebildet .The adapter 1 has at its second end 5 a sleeve 17 which extends into a recess 18 in the mating connector 6. Between the contact threads 13 of the mating connector 6 and the sleeve 17 of the adapter 1, a second seal 8 is arranged, which seals the contact tabs 13 of the mating connector 6 against the environment. The second seal 8 is designed as a radial seal ^ in the form of a shaft ring or a labyrinth seal.
Als zusätzliche Sicherungsmaßnahme kann der Adapter 1 nach dem Aufstecken auf den Steckanschluß 4 des Brennstoffeinspritzventils mittels eines Federbügels 11 oder einer ähnlichen Sicherungsvorrichtung gesichert werden, was ein Abrutschen des Adapters 1 vom Steckanschluß 4 verhindert und gleichzeitig das Einstecken des Gegensteckers 6 in den Adapter 1 erleichtert.As an additional security measure, the adapter 1 can be secured after being plugged onto the plug connection 4 of the fuel injector by means of a spring clip 11 or a similar securing device, which prevents the adapter 1 from slipping off the plug connection 4 and at the same time facilitates the insertion of the mating connector 6 into the adapter 1.
Der Gegenstecker 6 ist vorzugsweise aus Kunststoff gefertigt, wobei die Kontaktfahnen 13 des Gegensteckers 6 in den Kunststoff eingespritzt sind. Durch die Verwendung eines zusätzlichen Bauteils in Form des Adapters 1 kann eine vollständige Abdichtung der Kontaktfahnen 13 und 14 mittels der Dichtungen 7 und 8 erzielt und dabei auf lange Rüstzeiten und teure Werkzeuge zur Herstellung und Montage unterschiedlicher Steckersysteme verzichtet werden.The mating connector 6 is preferably made of plastic, the contact tabs 13 of the mating connector 6 being injected into the plastic. Through the use of an additional component in the form of the adapter 1, a complete sealing of the contact lugs 13 and 14 by means of the seals 7 and 8 can be achieved and long set-up times and expensive tools for producing and assembling different connector systems can be dispensed with.
