Description

Die Erfindung betrifft einen Fahrzeugscheinwerfer mit einer Lampenfassung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a vehicle headlight with a lamp socket according to the preamble of patent claim 1.

Aus der EP 0 547 013 B1 ist eine Lampenfassung für einen Kfz-Scheinwerfer bekannt, die im Wesentlichen aus einem Halter besteht, in das eine Lampe eingesetzt bzw. vormontiert ist. Die Einheit aus Halter und Lampe weist lampenseitig einen Bajonettflansch mit drei radial zu einer Halter- bzw. Lampenlängsachse angeordneten Bajonettlappen auf, die in einem Lampenhals eines Reflektors in entsprechenden Aussparungen verriegelbar sind. Die Aussparungen sind zu der Lampenfassung von U-förmigen Halteteilen einer ringförmig ausgebildeten Haltefeder teilweise abgedeckt. Im verriegelten Zustand verriegeln die Bajonettlappen gegenüber den U-förmigen Halteteilen der Feder. Nachteilig bei der bekannten Lampenfassung ist, dass die Feder relativ kostenintensiv mit drei Schrauben am Lampenhals des Reflektors befestigt werden muss. Weiterhin nachteilig ist, dass die Bajonettlappen lampenseitig angeordnet sind und die Lampe somit nicht universell für unterschiedliche Reflektoren einsetzbar ist.From EP 0 547 013 B1, a lamp holder for a motor vehicle headlight is known, which essentially consists of a holder into which a lamp is inserted or preassembled. The unit of holder and lamp has on the lamp side a bayonet flange with three radially arranged to a holder or lamp longitudinal axis bayonet lobes, which can be locked in a lamp neck of a reflector in corresponding recesses. The recesses are partially covered by the lamp socket of U-shaped holding parts of an annular retaining spring. When locked, the bayonet latches lock against the U-shaped retainers of the spring. A disadvantage of the known lampholder is that the spring must be mounted relatively costly with three screws on the lamp neck of the reflector. Another disadvantage is that the bayonet lobes are arranged on the lamp side and thus the lamp is not universally applicable to different reflectors.

Aus der EP 0 596 427 A1 ist ein Fahrzeugscheinwerfer mit einer Lampenfassung bekannt, die ein Federblechteil und ein mit demselben gelenkig verbundenes Steckergehäuse aufweist. Das Steckergehäuse weist gabelförmige Zinken auf, zwischen denen ein Sockel der Lampe gehalten ist. Durch Verschwenken des Steckergehäuses relativ zu dem Federblechteil wird die Lampe in eine vormontierte Stellung verbracht. Nachfolgend kann die Lampe mittels einstückig an dem Federblechteil angeordneten Bajonettlappen, die eine Bajonettfahne des Reflektors hintergreifen, an dem Reflektor gehaltert werden. Nachteilig hieran ist, dass die Montage der Lampe relativ aufwändig ist, da stets ein Verschwenken des Steckergehäuses erforderlich ist.From EP 0 596 427 A1 a vehicle headlamp with a lamp socket is known, which has a spring plate part and a plug housing hingedly connected thereto. The connector housing has fork-shaped prongs, between which a socket of the lamp is held. By pivoting the plug housing relative to the spring plate part, the lamp is moved to a pre-assembled position. Subsequently, the lamp can be held on the reflector by means of bayonet lugs arranged integrally on the spring plate part, which engage behind a bayonet lug of the reflector. The disadvantage of this is that the mounting of the lamp is relatively complex, since always a pivoting of the plug housing is required.

Aufgabe der vorliegenden Erfindung ist es daher, die bekannte Lampenfassung so zu verbessern, dass sie kostengünstig herstellbar, einfach zu montieren und die einzusetzende Lampe universell einsetzbar ist.Object of the present invention is therefore to improve the known lamp socket so that they can be produced inexpensively, easy to assemble and the lamp to be used is universally applicable.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.

Nach der Erfindung trägt das Federblechteil sowohl das Steckergehäuse als auch die Lampe. Bei einem Wechsel der Lampe ist der Halter durch Drehen aus der Bajonettverbindung mit dem Reflektor zu lösen. Danach ist der die Lampe tragende Halter, dessen Steckergehäuse mit elektrischen Zuleitungen verbunden ist, von Hand frei zugänglich und die defekte Lampe ist leicht und schnell gegen eine neue Lampe austauschbar. Das Steckergehäuse kann auch ohne das Steckergehäuse bei anderen Scheinwerfern verwendet werden.According to the invention, the spring plate part carries both the connector housing and the lamp. When replacing the lamp, the holder can be released by turning the bayonet connection with the reflector. Thereafter, the holder carrying the lamp, the connector housing is connected to electrical leads, freely accessible by hand and the defective lamp is easily and quickly interchangeable with a new lamp. The connector housing can also be used without the connector housing with other headlamps.

Weiterhin ist es vorteilhaft, wenn die Bajonettlappen als freie Enden zweier Federarme ausgebildet sind. Dadurch kann auf eine zusätzliche Feder verzichtet werden. Die Herstellung und Montage der Lampenfassung mit entsprechendem Lampenhals am Reflektor kann so vereinfacht und kostengünstiger gestaltet werden. Hierbei ist es weiterhin zweckmäßig, wenn der Lampenhals des Reflektors zwei Schrauben aufweist, deren Schraubenköpfe als Teil der Verriegelungseinrichtung von den Bajonettlappen hintergreifbar sind. Dadurch wird auch die Herstellung des Lampenhalses bzw. des Reflektors vereinfacht. Neben einem vereinfachten Lampenwechsel bei einem einfachen und kostengünstigen Aufbau führt die erfindungsgemäße Lösung zugleich zu einer geringeren Baugröße.Furthermore, it is advantageous if the bayonet lugs are designed as free ends of two spring arms. This can be dispensed with an additional spring. The manufacture and assembly of the lamp holder with a corresponding lamp neck on the reflector can be simplified and made cheaper. In this case, it is furthermore expedient for the lamp neck of the reflector to have two screws whose screw heads can be engaged behind the bayonet lugs as part of the locking device. As a result, the production of the lamp neck or the reflector is simplified. In addition to a simplified lamp replacement in a simple and inexpensive construction, the solution according to the invention also leads to a smaller size.

Gemäß einer bevorzugten Ausführungsform der Erfindung weisen die Federarme zum Halter hin einen ersten, in Richtung Reflektor hin gebogenen Schenkel auf, der über eine U-förmige Wölbung in einen zweiten den Bajonettlappen bildenden Schenkel übergeht und dessen freies Ende von dem Reflektor weggerichtet ist.According to a preferred embodiment of the invention, the spring arms towards the holder on a first, bent towards the reflector leg, which merges via a U-shaped curvature in a second leg forming the bayonet lobes and the free end is directed away from the reflector.

Durch die U-förmige Wölbung der Federarme und durch die vom Reflektor weggerichteten freien Enden der Bajonettlappen ist es möglich, den Halte unter Spannung in den Reflektor einzusetzen, so daß auf zusätzliche Federelemente verzichtet werden kann.Due to the U-shaped curvature of the spring arms and by the reflector directed away from the free ends of the bayonet lugs, it is possible to hold under Use voltage in the reflector, so that it can be dispensed with additional spring elements.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist der Bajonettlappen gegenüber einer Halterlängsachse in einem spitzen Winkel angeordnet.According to a further preferred embodiment of the invention, the bayonet flap is arranged opposite to a holder longitudinal axis at an acute angle.

Durch die Anordnung der Bajonettlappen in einem spitzen Winkel gegenüber der Halterlängsachse wird auf einfache Weise die notwendige Vorspannung im verriegelten Zustand erzeugt.Due to the arrangement of the bayonet lugs in an acute angle relative to the holder longitudinal axis the necessary bias voltage is generated in the locked state in a simple manner.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung weisen die Bajonettlappen an ihren freien Enden eine konkave Rasttaille auf, in die in der Verriegelungsstellung die benachbarte Schraube bzw. deren Schraubenkopf einrastet. Zur Erleichterung der Verriegelung weisen die Bajonettlappen an ihren freien Enden, in einer Entriegelungsstellung zum Schraubenkopf hin, eine Anlaufschräge auf.According to a further preferred embodiment of the invention, the bayonet tabs at their free ends on a concave detent waist, into which engages in the locking position, the adjacent screw or its screw head. To facilitate the locking, the bayonet tabs at their free ends, in an unlocked position towards the screw head, a run-on slope.

Durch die Anordnung von Anlaufschrägen wird der Verriegelungsvorgang vereinfacht. Die Anordnung einer konkaven Rasttaille an den Bajonettlappen ermöglicht eine einfache Verrastung bzw. Verriegelung der Bajonettlappen gegenüber den Schrauben bzw. den Schraubenköpfen.The arrangement of chamfers of the locking process is simplified. The arrangement of a concave detent waist on the bayonet lugs allows easy locking or locking of the bayonet lugs against the screws or the screw heads.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung weisen die Schraubenköpfe an ihren den freien Enden der Schrauben zugewandten Unterseiten hin einen Konus auf.According to a further preferred embodiment of the invention, the screw heads at their the free ends of the screws facing lower sides towards a cone.

Durch die Anordnung eines Konus' an der Unterseite der Schraubenköpfe wird die Verrastung der Schrauben gegenüber den Rasttaillen der Bajonettlappen weiter begünstigt, so daß auf einen zusätzlichen Rastclip, der ein ungewolltes Entriegeln der Lampenfassung verhindern soll, verzichtet werden kann.The arrangement of a cone 'on the underside of the screw heads, the locking of the screws against the locking waists of the bayonet tabs further favored, so that can be dispensed with an additional locking clip, which is intended to prevent accidental unlocking of the lamp holder.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung sind die Federarme an einem Federblechteil angeordnet, der mit einem Steckergehäuse über federnde Rastlappen und entsprechende Rastteile am Steckergehäuse verbindbar ist.According to a further preferred embodiment of the invention, the spring arms are arranged on a spring plate part, which is connectable to a connector housing via resilient locking tabs and corresponding latching parts on the connector housing.

Dadurch, daß Rastelemente an einem Federblechteil angeordnet sind, das mit einem Steckergehäuse selbstrastend verbindbar ist, vereinfacht sich die Montage des Halters erheblich. So kann auch insbesondere die Lampe leicht in dem Halter, der von dem Federblechteil und dem Steckergehäuse gebildet wird, montiert werden. Dadurch ist insbesondere auch ein einfacher Lampenwechsel bei Blindmontage möglich.Characterized in that latching elements are arranged on a Federblechteil, which is self-locking connected to a connector housing, the mounting of the holder simplifies considerably. Thus, in particular, the lamp can be easily mounted in the holder, which is formed by the spring plate part and the connector housing. As a result, in particular, a simple lamp replacement is possible with blind assembly.

Durch Einstecken der nicht dargestellten Steckertüllen in das Steckergehäuse 7 wird die elektrische Verbindung hergestellt. Die Lampe 3, die beispielsweise als H 7-Lampe ausgebildet ist, wird in das Steckergehäuse 7 eingesteckt. Anschließend wird der Halter 2 zusammen mit der Lampe 3 in den Lampenhals 29 des Reflektors 5 eingesetzt und soweit nach rechts gedreht, daß die Bajonettlappen 14 die Schraubenköpfe 32 hintergreifen und die Schrauben 31 bzw. die Schraubenköpfe 32 mit ihrem Konus 35 in der benachbarten Rasttaille 15 des jeweilige Bajonettlappens 14 verrasten. In der Raststellung rastet zugleich der Rastclip 28 in die entsprechende Rastnut 37 des Innenrandes 36 bzw. des Lampenhalses 29 ein. Zum Lampenwechsel muß lediglich der Halter aus seiner Verriegelungsstellung in entgegengesetzte Richtung in die Entriegelungsstellung gebracht und der Halter 2 aus dem Reflektor 5 herausgezogen werden. Nunmehr kann die Lampe 3 entfernt und der Halter 2 mit ausgewechselter Lampe 3 erneut in den Lampenhals 29 des Reflektors 5 eingesetzt werden.To mount the lamp holder 1, the spring plate 6 is placed on the connector housing 7 so that the locking tabs 17 and the locking apertures 18 engage with the locking parts 19, wherein the struts 20 of the connector housing 7 with their stops 23 on the bottom 9 of the Federblechteils. 6 support and their locking hooks 21 get caught in the locking openings 22 of the bottom 9. By inserting the plug grommets, not shown in the connector housing 7 is the electrical connection made. The lamp 3, which is formed for example as H 7 lamp, is inserted into the connector housing 7. Subsequently, the holder 2 is inserted together with the lamp 3 in the lamp neck 29 of the reflector 5 and turned so far to the right that the bayonet lugs 14 engage behind the screw heads 32 and the screws 31 and the screw heads 32 with its cone 35 in the adjacent detent waist 15th of the respective bayonet flap 14 lock. At the same time, the latching clip 28 engages in the latching position in the corresponding latching groove 37 of the inner edge 36 or of the lamp neck 29. For lamp replacement, only the holder must be brought from its locked position in the opposite direction in the unlocked position and the holder 2 are pulled out of the reflector 5. Now, the lamp 3 can be removed and the holder 2 can be used again with the lamp 3 replaced in the lamp neck 29 of the reflector 5.

Die Lampenfassung 1 wird somit in den Reflektor 5 über eine einerseits aus den Bajonettlappen 14 und andererseits aus dem Schraubenköpfen 32 bestehende Verriegelungseinrichtung verriegelt.The lamp holder 1 is thus locked in the reflector 5 via an existing on the one hand from the bayonet lugs 14 and on the other hand from the screw heads 32 locking device.

In den Figuren 7 bis 10 ist ein Fahrzeugscheinwerfer dargestellt, bei dem das Federblechteil 6 und das Steckergehäuse 7 ausschließlich durch eine einzige Rastvorrichtung miteinander verbunden sind, die aus federnden Rastlappen 17 des Federblechteils 6 und nasenartigen Rastteilen 19 des Steckergehäuses besteht. Das Steckergehäuse 7 ist mit nicht dargestellten elektrischen Zuleitungen verbunden und zwischen dem vom Reflektor wegweisenden Rastlappen 17 eingesetzt. Dabei greift das Steckergehäuse mit Steckanschlüssen für Flachstecker 36 der Lampe 3 in eine zentrale Durchgangsöffnung des Federblechteils 6 ein. In Figur 8 ist die Lampe 3 mit ihren Flachsteckern 36 in das Steckergehäuse 7 eingeführt und dadurch mit dem Halter 2 gehalten. Nach einem Hindurchführen eines Glaskolbens der Lampe 3 durch eine Öffnung 37 in dem Reflektor 5 liegt die Lampe 3 mit einem flanschartigen Sockelring 26 an einem umlaufenden Randbereich 38 der Öffnung 37 des Reflektors 5 an. Der Randbereich 38 ist von einem in der Öffnung 37 des Reflektors 5 festgesetzten separaten ringförmigen Fassungsteil 39 gebildet. Das Fassungsteil 39 weist zwei gegenüberliegende abgewinkelte Bajonettfahnen 40 auf, in deren Hinterschneidungen der Halter 2 mit seinen Bajonettlappen 14 eingreift. Die federnden Bajonettfahnen 14 des Halters 2 liegen unter Vorspannung an den Hinterschneidungen 41 der Bajonettfahnen 40 an und drücken den Sockelring 26 der Lampe 3 gegen den Randbereich 38 des Reflektors 5 (siehe Fig. 10).In Figures 7 to 10, a vehicle headlamp is shown, in which the spring plate 6 and the connector housing 7 are interconnected exclusively by a single locking device consisting of resilient locking tabs 17 of the spring plate 6 and nose-like locking parts 19 of the plug housing. The plug housing 7 is connected to electrical leads, not shown, and inserted between the groundbreaking from the reflector latching lugs 17. In this case, the plug housing engages with plug connections for tabs 36 of the lamp 3 in a central through hole of the spring plate part 6 a. In Figure 8, the lamp 3 is inserted with its tabs 36 in the connector housing 7 and thereby held with the holder 2. After passing a glass bulb of the lamp 3 through an opening 37 in the reflector 5, the lamp 3 rests with a flange-like base ring 26 against a circumferential edge region 38 of the opening 37 of the reflector 5. The edge region 38 is defined by a fixed in the opening 37 of the reflector 5 separate annular Holder part 39 is formed. The mount part 39 has two opposite angled bayonet lugs 40, in the undercuts of the holder 2 engages with its bayonet lugs 14. The resilient bayonet lugs 14 of the holder 2 are biased against the undercuts 41 of the bayonet lugs 40 and press the base ring 26 of the lamp 3 against the edge region 38 of the reflector 5 (see Fig. 10).
