Description

Die Erfindung betrifft einen Lampenträger für Kraftfahrzeuge mit einer Grundplatte, auf der mindestens eine Lampenfassung befestigt ist, wobei die Lampenfassung ein erstes, mit einer Bohrung zum Durchstecken der Lampe versehenes Fassungselement aufweist, mit einem zweiten Fassungselement, mit einer Leiterfolie, die auf einer Seite der Grundplatte verläuft und im Bereich des Sitzes der Lampenfassung mit einer aus der Kontaktfolienfläche herausbiegbaren Kontaktfahne versehen ist, wobei die Kontaktfahne durch eine Ausnehmung in der Grundplatte durchgesteckt ist und an der Lampenfassung unter Bildung einer Massekontaktstelle und einer Pluskontaktstelle festgelegt ist.The invention relates to a lamp holder for motor vehicles with a base plate on which at least one lamp socket is fastened, the lamp socket having a first socket element provided with a bore for pushing the lamp through, with a second socket element, with a conductor foil on one side of the socket The base plate extends and is provided in the area of the seat of the lamp holder with a contact tab that can be bent out of the contact foil surface, the contact tab being pushed through a recess in the base plate and fixed to the lamp holder to form a ground contact point and a positive contact point.

Es ist bekannt, als Lampenträger für sogenannte Mehrfachleuchten an Kraftfahrzeugen eine Grundplatte, meist aus Kunststoff hergestellt, zu verwenden und an dieser Grundplatte eine Leiterfolie festzulegen, die durch die bekannten Verfahren beispielsweise photographisch) mit Leiterbahnen versehen ist, die zu den einzelnen, auf dem Lampenträger sitzenden Lampenfassungen führen und dort Kontaktstellen bilden. Bei den bekannten Bauarten liegen die Leiterfahnen an starren Teilen der Lampenfassung an, so daß bei der Herstellung der Lampenfassung enge Toleranzen eingehalten werden müssen, um sicherzustellen, daß nach dem Einstecken der Lampe tatsächlich die Kontaktgabe gewährleistet ist. Es hat sich gezeigt, daß die Kontaktgabe trotz Einhaltung sehr enger Fertigungstoleranzen nicht zuverlässig sichergestellt werden kann, da insbesondere bei Erschütterungen, wenn sich auch nur eine leichte Veränderung im Sitz der Lampe ergibt, die Kontaktgabe unterbrochen wird.It is known to use a base plate, usually made of plastic, as a lamp holder for so-called multiple lights on motor vehicles, and to fix a conductor foil to this base plate, which is provided by the known methods (for example, photographically) with conductor tracks leading to the individual on the lamp holder lead seated lamp holders and form contact points there. In the known types, the conductor tabs rest on rigid parts of the lamp holder, so that close tolerances must be observed during the manufacture of the lamp holder, in order to ensure that contact is actually guaranteed after the lamp has been inserted. It has been shown that contact can not be reliably ensured despite compliance with very tight manufacturing tolerances, since contact is interrupted in particular in the event of vibrations, if there is even a slight change in the position of the lamp.

Der Erfindung liegt die Aufgabe zugrunde, einen Lampenträger zu schaffen, bei dem eine zuverlässige Kontaktierung der auf ihm befestigten Lampen möglich ist und der außerdem eine einfache Festlegung der Leiterfolie ermöglicht.The invention has for its object to provide a lamp holder, in which a reliable contacting of the lamps attached to it is possible and which also enables simple fixing of the conductor foil.

Die Erfindung besteht darin, daß die Bereiche der Lampenfassung, an denen die Leiterfolie zur Bildung der Kontaktstellen anliegt, federnd ausgebildet sind. Dadurch wird an den Kontaktstellen die Leiterfolie unter Wirkung einer Federkraft gegen die Lampe gepreßt, so daß die Kontaktgabe auch ohne Einhaltung enger Toleranzen bei der Fertigung einer Lampenfassung zuverlässig erfolgt.The invention consists in that the areas of the lamp socket, on which the conductor foil for forming the contact points, are designed to be resilient. Characterized the conductor film is pressed against the lamp under the action of a spring force at the contact points, so that the contact is made reliably even without observing close tolerances in the manufacture of a lamp holder.

In vorteilhafter Ausgestaltung der Erfindung ist das erste Fassungselement von einem fest mit der Grundplatte verbundenen Teil (Massejoch) mit einer parallel im Abstand zur Grundplattenoberfläche verlaufenden, in Richtung zur Grundplatte federnden Querstrebe und von einem zweiten Teil gebildet, wobei der zweite Teil (Fassungsbogen) mit der Bohrung zum Durchstecken der Lampe versehen ist und zwei Stützfüße, mit denen er auf der Grundplatte aufsitzt sowie einen über dem Massejoch zu liegen kommenden Bohrungsbereich umfaßt, wobei Massejoch und Fassungsbogen derart korrespondierend ausgebildet sind, daß die Oberseite der Querstrebe des Massejochs in dem Bohrungsbereich eine untere, etwas innerhalb der Bohrungskontur horizontal verlaufende Wand bildet. Die Querstrebe des Massejochs bildet dann eine Kontaktstelle, wenn die Leiterfolie um die Querstrebe gebogen wird. Da die Querstrebe teilweise innerhalb der Bohrungskontur verläuft, bewirkt das Einschieben der Lampe, daß die nachgiebige bzw. federnde Querstrebe so durchgebogen wird, daß die Lampe durch die Bohrung eingeschoben werden kann. Dadurch drückt die Querstrebe dann in Richtung auf die Lampe und stellt somit sicher, daß die Leiterfolie fest gegen die Lampe gepreßt wird.In an advantageous embodiment of the invention, the first mounting element is formed by a part (mass yoke) that is fixedly connected to the base plate, with a transverse strut that runs parallel to the base plate surface and resilient in the direction of the base plate, and by a second part, the second part (mounting arch) being included the hole for pushing through the lamp is provided and two support feet with which it rests on the base plate and includes a bore area to lie above the mass yoke, the mass yoke and the mounting bracket being designed in such a way that the top of the cross strut of the mass yoke in the bore area forms the lower wall, which runs somewhat horizontally within the bore contour. The cross strut of the mass yoke then forms a contact point when the conductor foil is bent around the cross strut. Since the cross strut extends partially within the bore contour, the insertion of the lamp causes the resilient or resilient cross strut to be bent so that the lamp can be inserted through the bore. This then pushes the cross strut in the direction of the lamp and thus ensures that the conductor foil is pressed firmly against the lamp.

In weiterer vorteilhafter Ausgestaltung ist als zweites Fassungselement ein in der Art eines umgestülpten U mit einem langen und einem kurzen Schenkel ausgebildeter Federbügel vorgesehen, der mit dem langen Schenkel auf der Grundplatte befestigt ist und dessen kurzer, freier Schenkel in Einschieberichtung der Lampe gesehen hinter der Bohrungskontur des ersten Fassungselementes zu liegen kommt und einen federnden Anschlag für die Lampe bildet. Bevor die Lampe eingeschoben wird, wird dann die Kontaktfahne über den Bereich des kürzeren Schenkels geführt, wobei nach dem Einschieben der Lampe der üblicherweise den Pluskontakt darstellende Fuß der Lampe die Kontaktfahne gegen den kürzeren Schenkel drückt, so daß dieser etwas federnd nachgibt und daher bewirkt, daß auch an der zweiten Kontaktstelle die Kontaktgabe unter federnder Beaufschlagung der Leiterfahne erfolgt.In a further advantageous embodiment, a spring bracket designed in the manner of an inverted U with a long and a short leg is provided as the second socket element, which is fastened to the base plate with the long leg and whose short, free leg, seen in the insertion direction of the lamp, behind the bore contour of the first socket element comes to rest and forms a resilient stop for the lamp. Before the lamp is inserted, the contact lug is then guided over the area of the shorter leg, the foot of the lamp, which usually represents the positive contact, pressing the contact lug against the shorter leg after the lamp has been inserted, so that it yields somewhat resiliently and therefore causes that contact is also made at the second contact point under resilient action on the conductor flag.

Wenn am Fassungsbogen ein unterhalb in die Kontur des kürzeren Schenkels ragender Spannvorsprung ausgebildet ist, wird die Kontaktfahne durch Auschieben des Fassungsbogens gespannt und legt sich an das zweite Fassungselement an. Die Festlegung des Fassungsbogens erfolgt in vorteilhafter Weise einrastend an der Grundplatte.If a clamping projection projecting below the contour of the shorter leg is formed on the frame, the contact lug is tensioned by sliding out the frame and lies against the second frame element. The setting sheet is advantageously locked in place on the base plate.

In sehr vorteilhafter Ausgestaltung der Erfindung ist in dem Bereich des Federbügels ein Haken zum Einhängen des oberen Endabschnittes der Kontaktfahne ausgebildet. Damit wird der Befestigungsvorgang der Leiterfolie sehr einfach, da die Kontaktfahne durch die Grundplatte hindurch um das Massejoch geführt werden kann und dann am oberen Ende des Federbügels mit einer Ausnehmung eingehängt wird, so daß eine vorläufige Fixierung der Kontaktfolie möglich ist, so lange die Fassungsbogen zur endgültigen Fixierung der Kontaktfahnen noch nicht befestigt sind.In a very advantageous embodiment of the invention, a hook is formed in the area of the spring clip for hanging the upper end portion of the contact tab. This makes the process of attaching the conductor foil very simple, since the contact lug can be passed through the base plate around the mass yoke and is then hung at the upper end of the spring clip with a recess, so that a preliminary fixation of the contact foil is possible as long as the mounting bracket final fixation of the contact flags are not yet fixed.

Vorteilhafte Weiterbildungen der Erfindung werden in den weiteren Ansprüchen beschrieben.Advantageous developments of the invention are described in the further claims.

In Fig. 1 bezeichnet 1 einen Lampenträger, der nur ausschnittsweise dargestellt ist und eine erfindungsgemäße Lampenfassung 4 trägt. Der Lampenträger 1 besteht im wesentlichen aus einer Grundplatte 2, auf deren einer Seite eine Kontaktfolie 3 verläuft, die die Spannungsversorgung zu den einzelnen Lampenfassungen übernimmt. Die Lampenfassungen sind im Prinzip gleich aufgebaut, es genügt daher, den Aufbau anhand einer Lampenfassung näher zu beschreiben.In Fig. 1, 1 denotes a lamp holder, which is shown only in sections and carries a lamp holder 4 according to the invention. The lamp holder 1 consists essentially of a base plate 2, on one side of which a contact foil 3 runs, which takes over the voltage supply to the individual lamp holders. In principle, the lamp holders have the same structure, so it is sufficient to describe the structure in more detail using a lamp holder.

Die Lampenfassung 4 besteht aus einem ersten Fassungselement 8, welches das Massejoch 6 sowie den Fassungsbogen 7 umfaßt. Ein zweites Fassüngselement 5 ist als Federbügel ausgebildet und wird im folgenden so bezeichnet: Der Federbügel 5 ist in der Art eines umgestülpten U's ausgebildet und weist einen langen Schenkel 5a auf, mit dem er auf der Grundplatte befestigt ist. Dies kann einstückig geschehen. Ein zweiter, kürzerer Schenkel 5b dient in noch weiter unten beschriebenen Weise als Anschlag und zur Bildung einer Kontaktstelle für eine eingeschobene Lampe 9.The lamp socket 4 consists of a first socket element 8, which comprises the mass yoke 6 and the socket sheet 7. A second mounting element 5 is designed as a spring clip and is referred to below as follows: The spring clip 5 is designed in the manner of an inverted U and has a long leg 5a with which it is fastened to the base plate. This can be done in one piece. A second, shorter leg 5b serves in the manner described below as a stop and to form a contact point for an inserted lamp 9.

Das Massejoch 6 besitzt zwei Füße 10 und 11, die durch eine Querstrebe 12 miteinander verbunden sind. Zwischen den Füßen ist ein Raum zum Durchstecken einer Kontaktfahne 14, die als aus der Kontaktfolie 3 herausbiegbare Fahne ausgestaltet ist. Zum Befestigen der Leiterfolie 3 wird diese auf eine Seite der Grundplatte gebracht und kann dort schon vorfixiert werden, was mit Hilfe von in Fig. 2 angedeuteten Nocken 32 geschehen kann. Zusätzlich oder ausschließlich kann die Leiterfolie auf der Grundplatte aber auch durch Kleben, heißsiegeln oder z. B. durch Ultraschallschweißen fixiert werden.The mass yoke 6 has two feet 10 and 11, which are connected by a cross strut 12. Between the feet is a space for inserting a contact lug 14, which is designed as a lug that can be bent out of the contact foil 3. To attach the conductor foil 3, this is brought to one side of the base plate and can already be pre-fixed there, which can be done with the aid of cams 32 indicated in FIG. 2. Additionally or exclusively, the conductor film on the base plate can also be glued, heat sealed or z. B. be fixed by ultrasonic welding.

Die dem Fassungselement 4 zugeordnete Kontaktfahne 14 wird durch eine Ausnehmung 13 (vgl. Fig. 1) der Grundplatte 2 hindurchgeführt und um die Querstrebe 12 des Massejochs in der angedeuteten Weise gelegt. Am oberen Endabschnitt 21 der Kontaktfahne 14 ist eine Ausstanzung 34 vorgesehen, mit der dieses obere Ende 21 in einem am Federbügel abstehenden Haken 20 eingehängt wird. Eine Lamelle 33, die in die Ausstanzung 34 in der Kontaktfahne 14 hineinragt und Teil der Kontaktfahne ist, drückt gegen den Rücken des Hakens 20 und bewirkt so, daß das obere Ende 21 am Federbügel 5 vorfixiert ist.The contact lug 14 assigned to the socket element 4 is passed through a recess 13 (cf. FIG. 1) of the base plate 2 and placed around the cross strut 12 of the mass yoke in the manner indicated. On the upper end section 21 of the contact lug 14, a punched-out 34 is provided, with which this upper end 21 is hooked into a hook 20 protruding from the spring clip. A lamella 33, which protrudes into the punched-out portion 34 in the contact lug 14 and is part of the contact lug, presses against the back of the hook 20 and thus causes the upper end 21 to be pre-fixed on the spring clip 5.

Der Fassungsbogen 7 besitzt eine Bohrung 16, die mit einem Bohrungsbereich 16a über der Querstrebe 12 und damit über dem Massejoch 6 in aufgesteckter Stellung des Fassungsbogens 7 zu liegen kommt. Innerhalb der Bohrung sind - üblicherweise zwei - Führungsnuten 19 für an der Lampe 9 ausgebildete Arretierungsnocken 24 eingebracht, in denen die Nocken 24 während des Einschiebens der Lampe 9 geführt werden. Der Fassungsbogen 7 besitzt weiterhin zwei Stützfüße 15a und 15b, die in ihrer Höhe so abgestimmt sind, daß der vordere Bohrungsbereich 16a auf der Querstrebe 12 aufsitzt, wenn der Fassungsbogen 7 in die in Fig. 2 dargestellte Position gebracht ist. Die Bohrung besitzt in dem Bohrungsbereich 16a einen Durchbruch 17, der in aufgesteckter Stellung des Fassungsbogens von der Querstrebe 12 verschlossen wird. Dieser Durchbruch 17 schafft die Möglichkeit, eine Kontaktstelle, üblicherweise ist dies die Massekontaktstelle, zu verwirklichen, die unter Spannung die Kontaktfahne 14 in diesem Bereich an die Lampe 9 drückt. Da die Querstrebe 12 mit ihrer Oberfläche in der Art einer Sekante die Bohrung 16 durchsetzt, wenn der Fassungsbogen 7 aufgesteckt ist, kann die Lampe 9, deren Fassungsradius dem Bohrungsradius 16 entpricht, nur eingeschoben werden, indem die Querstrebe 12 etwas in Pfeilrichtung M nach unten gebogen wird. Hierzu ist die Querstrebe so dünn ausgebildet, daß sie eine entsprechende Durchbiegung ausführen kann. Diese Biegespannung bewirkt dann, daß die Kontaktfahne 14 mit der Kontaktstelle 23 in dem Durchbruch 17 gegen die Lampe gedrückt wird und daher den Massekontakt federnd bildet.The frame bow 7 has a bore 16, which comes to rest with a bore region 16a above the cross strut 12 and thus above the mass yoke 6 in the plugged-on position of the frame bow 7. Guide grooves 19 for locking cams 24 formed on the lamp 9, in which the cams 24 are guided during the insertion of the lamp 9, are introduced into the bore, usually two. The frame bow 7 also has two support feet 15a and 15b, which are adjusted in height so that the front bore area 16a is seated on the cross strut 12 when the frame bow 7 is brought into the position shown in FIG. 2. The bore has an opening 17 in the bore area 16a, which is closed by the cross strut 12 in the plugged-on position of the mounting bracket. This opening 17 creates the possibility of realizing a contact point, usually this is the ground contact point, which presses the contact lug 14 against the lamp 9 in this area under tension. Since the cross strut 12 penetrates the bore 16 with its surface in the manner of a secant when the socket arch 7 is attached, the lamp 9, the socket radius of which corresponds to the radius of the bore 16, can only be inserted by the cross strut 12 downward in the direction of the arrow M. is bent. For this purpose, the cross strut is so thin that it can perform a corresponding deflection. This bending stress then causes the contact lug 14 with the contact point 23 in the opening 17 to be pressed against the lamp and therefore forms the ground contact in a resilient manner.

Wenn nun nach der Vorfixierung der Kontaktfahne 14 am Federbügel 5 der Fassungsbogen 7 aufgesteckt wird, ergibt sich ein Verlauf der in Fig. 1 nur gestrichelt dargestellten Kontaktfahne 14, wie er aus Fig. 2 ersichtlich ist. Der in Richtung auf den Federbügel 5 ausgebildete Spannvorsprung 18 am Fassungsbogen 7 verspannt die Kontaktfahne 14 im Haken 20 und bewirkt, daß diese sich glatt an die Oberfläche des kurzen Schenkels 5b anlegt. Im Bereich des Fassungsbogens 7 verläuft die Kontaktfahne 14 zunächst über die Querstrebe 12 und damit teilweise innerhalb der Bohrung 16, wird dann unter den die Füße 15a und 15b des Fassungsbogens verbindenden Quersteg gedrückt und entlang bis zum Umbug um den Spannvorsprung 18 geführt. Da der Spannvorsprung 18 mit einer derartigen Länge ausgebildet ist, daß er bis unter die Kontur des kürzeren Schenkels 5b reicht, wird die Kontaktfahne am Federbügel anliegend gespannt. Der Fassungsbogen wird dann an den Auflagestellen auf der Grundplatte 2 beispielsweise geklebt, ultraschallgeschweißt oder durch Schrauben befestigt. Am einfachsten erfolgt die Befestigung natürlich verrastend, was anhand des in den weiteren Figuren dargestellten Ausführungsbeispiels noch näher beschrieben wird.If, after the pre-fixation of the contact lug 14 on the spring clip 5, the socket sheet 7 is plugged in, there is a profile of the contact lug 14 shown only in broken lines in FIG. 1, as can be seen in FIG. 2. The formed in the direction of the spring clip 5 clamping projection 18 on the frame bow 7 tensions the contact tab 14 in the hook 20 and causes it to lie smoothly on the surface of the short leg 5b. In the area of the socket sheet 7, the contact lug 14 initially runs over the cross strut 12 and thus partly within the bore 16, is then pressed under the cross piece connecting the feet 15a and 15b of the socket sheet and is guided along until the fold around the clamping projection 18. Since the clamping projection 18 is formed with such a length that it is below the contour of the shorter leg 5b is sufficient, the contact lug is stretched against the spring clip. The frame sheet is then, for example, glued, ultrasonically welded or fastened by screws at the support points on the base plate 2. The easiest way of fastening is of course latching, which is described in more detail with reference to the embodiment shown in the other figures.

Nach der Befestigung des Fassungsbogens 7 und der damit bewirkten Spannung der Kontaktfahne 14 wird die Lampe 9 eingeschoben, die in Fig. 2 in einer Zwischenstellung gezeigt ist. Dabei ist angedeutet, daß die Arretierungsnocken 24 (nur einer gezeigt) in einer Nut innerhalb der Bohrung 16 geführt werden. Wird die Lampe noch weiter in Pfeilrichtung F eingeschoben, gelangt der Arretierungsnocken 24 außerhab der Kontur des Fassungsbogens 7. Danach kann die Lampe gedreht werden, was so lange geschieht, bis sie in einen Anschlag 25, der am Spannvorsprung ausgebildet ist, anliegt und dann nicht mehr weiterverdreht werden kann. In diesem Bereich des Anschlags 25 kann eine Kerbe 25a in die Kontur des Fassungsbogens führen, so daß die Lampe entgegen der Pfeilrichtung F etwas nach vorne gedrückt wird.After the mounting of the socket sheet 7 and the tension of the contact lug 14 caused thereby, the lamp 9 is inserted, which is shown in an intermediate position in FIG. 2. It is indicated that the locking cams 24 (only one shown) are guided in a groove within the bore 16. If the lamp is pushed further in the direction of arrow F, the locking cam 24 gets out of the contour of the socket sheet 7. Then the lamp can be rotated, which happens until it abuts a stop 25, which is formed on the clamping projection, and then not can be rotated further. In this area of the stop 25, a notch 25a can lead into the contour of the socket sheet, so that the lamp is pushed slightly forward against the direction of the arrow F.

Durch das weitere Einschieben der Lampe 9 in die endgültige Position wird der Federbügel 5 ebenfalls in Pfeilrichtung F gedrückt, wobei eine entgegen der Pfeilrichtung F wirkende Federkraft erzeugt wird, die dann die Kontaktfahne 14 gegen den Fuß der Lampe 9 drückt, so daß dort der Pluskontakt 22 ebenfalls unter Spannung gebildet wird. Die Querstrebe 12 hat sich im Bereich unterhalb des Durchbruchs 17 durch das Einschieben der Lampe in Pfeilrichtung M durchgebogen und erzeugt dort ebenfalls eine Federkraft, so daß beide Kontaktstellen 22, 23 zuverlässig die Kontaktfolie gegen die Lampe drücken. Dadurch ist eine sehr zuverlässige Kontaktgabe über lange Zeit gewährleistet. Außerdem ist die Festlegung und Vorfixierung der Folie ohne besondere Hilfsmittel sehr einfach möglich, so daß die Montage sehr leicht vorgenommen werden kann. Eine Beschädigung der üblicherweise aus Kunststoff hergestellten Fassungselemente ist ebenfalls nicht zu befürchten, da beim Einschieben der Lampe der Einschiebeweg durch den Anschlag, den die Glaskappe der Lampe an dem Fassungsbogen 7 bildet, begrenzt ist und damit der Biegeweg des Federbügels 5. Es besteht somit ein Überlast- und Verdrehschutz. Anhand der weiteren Figuren wird nun ein vorteilhaftes Ausführungsbeispiel beschrieben, welches nach den anhand der Fig. 1 und 2 erläuterten Prinzipien realisiert ist.By pushing the lamp 9 further into the final position, the spring clip 5 is also pressed in the direction of the arrow F, a spring force acting against the direction of the arrow F being generated, which then presses the contact tab 14 against the base of the lamp 9, so that there is the positive contact 22 is also formed under tension. The cross strut 12 has bent in the area below the opening 17 by inserting the lamp in the direction of arrow M and also produces a spring force there, so that both contact points 22, 23 reliably press the contact foil against the lamp. This ensures a very reliable contact over a long period of time. In addition, the fixing and pre-fixing of the film is very easy without special aids, so that the assembly can be carried out very easily. Damage to the socket elements, which are usually made of plastic, is also not to be feared, since when the lamp is inserted, the insertion path is limited by the stop which the glass cap of the lamp forms on the socket arch 7, and thus the bending path of the spring clip 5 Overload and twist protection. Based on the other figures, an advantageous exemplary embodiment is now described, which is implemented according to the principles explained with reference to FIGS. 1 and 2.

Fig. 3 zeigt eine Draufsicht auf einen Fassungsträger, wobei die Grundplatte 2 zu erkennen ist, auf der mehrere Fassungen 4a, 4b, 4c, 4d und 4e ausgebildet sind. Die Fassungen sind alle ohne den Fassungsbogen 7 dargestellt, der in Fig. 6 und 6b gezeigt ist. Ein derartiger Lampenträger ist geeignet, die im Heckbereich eines Kraftfahrzeuges angeordneten Lampen aufzunehmen. Zusätzlich zu den einzelnen Lampenfassungen befindet sich auf der Grundplatte 2 eine Lasche 6, die unter Bildung eines spitzen Winkels von der Grundplatte abragt und die Stelle des Spannungsversorgungsanschlusses 27 für die gesamten Lampenfassungen darstellt, wie weiter unten noch ausgeführt wird.FIG. 3 shows a top view of a frame carrier, wherein the base plate 2 can be seen on which a plurality of frames 4a, 4b, 4c, 4d and 4e are formed. The versions are all shown without the version sheet 7 shown in Figs. 6 and 6b. Such a lamp holder is suitable for accommodating the lamps arranged in the rear area of a motor vehicle. In addition to the individual lamp sockets, there is a tab 6 on the base plate 2 which protrudes from the base plate at an acute angle and represents the location of the voltage supply connection 27 for the entire lamp sockets, as will be explained further below.

Wie Fig. 4 zeigt, ist jeweils ein Federbügel 5 und ein Massejoch 6 an jeder Lampenfassung einstückig mit der Grundplatte hergestellt und die oben beschrieben federnd ausgestaltet. Im Unterschied zu dem in Fig. 1 gezeigten Massejoch besitzt jedes Massejoch 6 der in Fig. 4 gezeigten Bauart unterhalb der Querstrebe eine Schlitz 28, durch den entsprechend die Kontaktfahne 14 durchgeschoben und umgebogen werden kann. Ebenfalls zu erkennen ist der am Federbügel 5 ausgebildete Haken 20.As shown in FIG. 4, a spring clip 5 and a mass yoke 6 are made in one piece on each lamp holder with the base plate and the spring described above is designed to be resilient. In contrast to the mass yoke shown in FIG. 1, each mass yoke 6 of the type shown in FIG. 4 has a slot 28 below the cross strut, through which the contact tab 14 can be pushed and bent accordingly. The hook 20 formed on the spring clip 5 can also be seen.

Fig. 5 zeigt eine Leiterfolie 3, wie sie zur Kontaktierung der einzelnen Lampenfassungen 4a bis 4e geeignet ist. Es sind dabei die einzelnen Kontaktzungen 3a bis 3e zu erkennen, welche aus der Fläche der Folie herausbiegbar sind. Die Leiterbahnen können durch photographische Verfahren aufgebracht werden. An jeder Leiterfahne ist eine Massenkontaktbahn und eine Pluskontaktbahn ausgebildet, die jeweils durch Isolierbahnen 35 voneinander getrennt sind. Die Bereiche, in denen nach dem Umbiegen der einzelnen Kontaktfahnen und dem Festlegen in der oben beschriebenen Weise die Kontaktstellen 23 und 22 entstehen, können die Kontaktfahnen verzinnt sein, was in Fig. 5 ebenfalls an diesen Stellen durch die Balken angedeutet ist.FIG. 5 shows a conductor foil 3 as is suitable for contacting the individual lamp holders 4a to 4e. The individual contact tongues 3a to 3e can be seen, which can be bent out of the surface of the film. The conductor tracks can be applied by photographic processes. A mass contact track and a positive contact track are formed on each conductor lug, and are each separated from one another by insulating tracks 35. The areas in which the contact points 23 and 22 arise after the bending of the individual contact tabs and the fixing in the manner described above, the contact tabs can be tinned, which is also indicated at these points in FIG. 5 by the bars.

Am oberen Endabschnitt jeder einzelnen Kontaktfahne ist die Ausstanzung 34 zu erkennen, mit der die Kontaktfahne zur Festlegung in die Haken 20 der Federbügel 5 eingehängt werden. Die Lamellen 33 bewirken dann die Vorspannung.On the upper end section of each individual contact lug, the punched-out 34 can be seen, with which the contact lug is hung in the hooks 20 of the spring clips 5 for fixing. The slats 33 then cause the bias.

Eine vergrößerte Darstellung einer Lampenfassung im Querschnitt zeigt die Fig. 6, wobei der Fassungsbogen 7 in einer aufgesteckten Position gezeigt ist. Die Führung der nicht dargestellten Kontaktfahnen 14 geschieht in der anhand der Fig. 2 beschriebenen Art und Weise. Zur Einschiebeerleichterung ist die Nut 19 sich nach vorne erweiternd ausgebildet. Nach dem Einschieben der ebenfalls nicht gezeigten Lampe rasten die ausgebildeten Arretierungsnocken in die Kerbe 25a bzw. 25b ein, wodurch der Verdrehschutz sichergestellt ist.6 shows an enlarged illustration of a lamp holder in cross section, the holder bow 7 being shown in an attached position. The contact lugs 14, not shown, are guided in the manner described with reference to FIG. 2. To facilitate insertion, the groove 19 is designed to widen forward. After the lamp, which is also not shown, is inserted, the locking cams formed snap into the notches 25a and 25b, as a result of which the protection against rotation is ensured.

Wie in Fig. 6a und 6b gezeigt ist, erfolgt die Befestigung des Fassungsbogens 7 einrastend, wozu dieser an den Füßen 15a und 15b Rastnasen 30 aufweist, die unter entsprechende Rastvorsprünge 29 an der Grundplatte 2 greifen und die Verrastung ermöglichen.As shown in FIGS. 6a and 6b, the mounting bracket 7 is fastened in a snap-in manner, for which purpose it has latching lugs 30 on the feet 15a and 15b, which engage under corresponding snap-in projections 29 on the base plate 2 and enable latching.

In Fig. 7 ist eine Detaildarstellung des Spannungsversorgungsanschlusses 27 gezeigt, wobei zu erkennen ist, daß die Lasche 26 unter Bildung eines spitzen Winkels aus der Fläche der Grundplatte 2 abragt. Um diese Lasche 26 wird der Folienabschnitt 31 für den Spannungsversorgungsanschluß (vgl. Fig. 5) gebogen, wobei dann ein entsprechend ausgebildeter, nicht näher gezeigter Mehrfachstecker aufgeschoben werden kann und auch dadurch eine Festlegung der Folie und eine zuverlässige Kontaktgabe gewährleistet. Zur Vorfixierung der Leiterfolie in diesem Bereich sind ebenfalls Ausstanzungen 34a in die Folie eingebracht, mit denen der Endabschnitt des Bereichs 31 der Folie 3 eingehängt und damit vorfixiert werden kann. Insgesamt schafft die Erfindung einen Lampenträger, bei dem die Folie ohne Zuhilfenahme irgendwelcher Hilfsmittel befestigt werden kann, bei dem die Kontaktgabe sehr zuverlässig an jeder einzelnen Lampenfassung erfolgt, bei dem weder gelötet oder Verdrahtungen vorgenommen werden müssen und der außerdem billig und einfach herstellbar ist.FIG. 7 shows a detailed illustration of the voltage supply connection 27, wherein it can be seen that the tab 26 protrudes from the surface of the base plate 2 by forming an acute angle. The film section 31 for the voltage supply connection (cf. FIG. 5) is bent around this tab 26, in which case an appropriately designed, not similar forth shown multiple plug can be pushed on and thereby also ensures a fixation of the film and a reliable contact. To pre-fix the conductor foil in this area, punched-out portions 34a are also made in the foil, with which the end section of the area 31 of the foil 3 can be hooked in and thus pre-fixed. Overall, the invention provides a lamp holder in which the film can be attached without the aid of any auxiliary means, in which contact is made very reliably on each individual lamp holder, in which neither soldering nor wiring has to be carried out, and which is also inexpensive and easy to produce.
