Abstract

Light bulbs of a multi chamber vehicle lamp are inserted into a lamp carrier made of sheet metal. Conductor strips are stamped out of the sheet metal for current conduction. The lamp carrier forms a common mass connection for all light bulbs. The contacting to the respective center pole of the light bulbs is effected directly by the free end portion of the conductor strip which is stamped out from a region of the lamp carrier remote from the light bulb socket. By a deformation of the conductor strip, the end portion is placed on the center axis of the opening accommodating the light bulb, and engages the center pole of the light bulb under pretension.

Description

Die Erfindung bezieht sich auf eine Fahrzeugleuchte mit einem aus einer Blechplatine hergestellten Lampenträger, in den mehrere die Glühlampen aufnehmende Öffnungen eingebracht sind, in die die Glühlampen mit ihrem hülsenförmigen Sockel elektrisch leitend eingesetzt sind und aus dem Leiterbahnen ausgetanzt sind, die als elektrische Zuleitungen für die einzelnen Glühlampen dienen und mit einem Kontakt verbunden sind, der federnd am Mittelpol der jeweiligen Glühlampe anliegt.The invention relates to a vehicle lamp with a lamp holder made from a sheet metal plate, into which a plurality of openings for receiving the incandescent lamps are introduced, into which the incandescent lamps are inserted in an electrically conductive manner with their sleeve-shaped base and punched out of the conductor tracks, which serve as electrical leads for the serve individual light bulbs and are connected to a contact which resiliently abuts the center pole of the respective light bulb.

Bei den bekannten Fahrzeugleuchten dieser Art (DE-B-2441 330) reichen die aus dem Lampenträger ausgestanzten Leiterbahnen mit ihrem einen Ende bis nahe an die die Glühlampen aufnehmenden Öffnungen in dem Lampenträger heran. Zur elektrischen Verbindung dieser Leiterbahnen mit dem Mittelpol der Glühlampen sind auf die Leiterbahnen gabelförmig geschlitzte Kontaktfedern klemmend aufgeschoben, die mit ihrem freien Ende unter Vorspannung an dem Mittelpol der Glühlampe anliegen.In the known vehicle lights of this type (DE-B-2441 330), the conductor tracks punched out of the lamp holder extend with one end close to the openings in the lamp holder that receive the incandescent lamps. For the electrical connection of these conductor tracks to the center pole of the incandescent lamps, fork-shaped, slotted contact springs are clamped onto the conductor tracks, and their free end is biased against the center pole of the incandescent lamp.

Aufgabe der Erfindung ist es, die elektrische Verbindung von der Leiterbahn zum Mittelpol der Glühlampe zu vereinfachen und zu verbilligen, und zwar durch Wegfall der zusätzlichen Kontaktfeder. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der jeweilige Kontakt als Endabschnitt der Leiterbahn aus einem von der den Glühlampensockel aufnehmenden Öffnung entfernt liegenden Bereich des Lampenträgers ausgestanzt und durch Deformation der Leiterbahn in die mittige Lage unterhalb der die Glühlampe aufnehmenden Öffnung gebracht ist.The object of the invention is to simplify and reduce the cost of the electrical connection from the conductor track to the center pole of the incandescent lamp, specifically by eliminating the additional contact spring. This object is achieved according to the invention in that the respective contact as the end section of the conductor track is punched out of an area of the lamp holder which is distant from the opening receiving the lamp base and is brought into the central position below the opening receiving the lamp by deformation of the conductor track.

Bei einer vorteilhaften Ausführungsform des Erfindungsgedankens sind die einzelnen Leiterbahnen im Bereich der Öffnungen zur Aufnahme der Glühlampen Z-förmig verlaufend ausgestanzt, wobei die Endabschnitte an den Öffnungen vorbeiführt und die Mittelabschnitte der Z-Form so deformiert sind, daß die freien Endabschnitte der Z-Form mittig unterhalb der Öffnungen liegen. Diese Ausführungsform ist besonders raumsparend. Bei einer Möglichkeit der weiteren Ausgestaltung des Erfindungsgedankens sind die freien Endabschnitte durch Verbiegen des Mittelabschnitts der Z-Form um 180° aus dem Lampenträger herausgeklappt. Diese Ausführungsform hat den zusätzlichen Vorteil, daß neben dem gradlinig verlaufenden Endabschnitt auch der sich daran anschließende um 180° aus dem Lampenträger herausgeklappte Mittelabschnitt auf Biegung und der letztere noch auf Torsion beansprucht wird. Eine derartig gestaltete Feder ergibt eine sehr günstige Federkennlinie.In an advantageous embodiment of the inventive concept, the individual conductor tracks in the area of the openings for receiving the incandescent lamps are punched out in a Z-shape, the end sections leading past the openings and the central sections of the Z-shape being deformed such that the free end sections of the Z-shape lie in the middle below the openings. This embodiment is particularly space-saving. In one possibility of further developing the inventive concept, the free end sections are folded out of the lamp holder by bending the central section of the Z shape by 180 °. This embodiment has the additional advantage that, in addition to the rectilinear end section, the adjoining central section, which is folded out by 180 ° from the lamp holder, is also subjected to bending and the latter to torsion. A spring designed in this way results in a very favorable spring characteristic.

Bei einer anderen Möglichkeit der weiteren Ausgestaltung der Erfindung werden die Endabschnitte durch Einbringen einer Haarnadelfalte in den Mittelabschnitt der Z-Form in die mittige Lage zur Aufnahme der Glühlampen gebracht. Zusätzlich sind die freien Endabschnitte der Z-Form abgekröpft. Diese Ausführungsform ist durch einfache Werkzeuge kostengünstig herstellbar.In another possibility of a further embodiment of the invention, the end sections are brought into the central position for receiving the incandescent lamps by introducing a hairpin fold into the central section of the Z shape. In addition, the free end sections of the Z shape are bent. This embodiment can be produced inexpensively using simple tools.

Bei einer weiteren vorteilhaften Ausgestaltung des Erfindungsgedankens ist der Endabschnitt der Leiterbahnen von der Glühlampenöffnung wegweisend verlaufend ausgestanzt und um 180° abgebogen, derart, daß sein freies Ende am Mittelpol der jeweiligen Glühlampe unter Vorspannung anliegt. Mit dieser und den vorstehend beschriebenen Ausführungsformen des Erfindungsgedankens ist es möglich, daß der unterhalb der Glühlampenöffnung zu liegen kommende Endabschnitt von allen Leiterbahnen aus dem Lampenträger auszustanzen ist.In a further advantageous embodiment of the concept of the invention, the end section of the conductor tracks is punched out to point away from the incandescent lamp opening and bent through 180 ° in such a way that its free end rests under prestress on the central pole of the respective incandescent lamp. With this and the embodiments of the inventive concept described above, it is possible for the end section to be located below the incandescent lamp opening to be punched out of the lamp holder by all conductor tracks.

Zur Abänderung der Federkennlinie des federnden Abschnittes der ausgestanzten Leiterbahn ist es zweckmäßig, den Endabschnitt der ausgestanzten Leiterbahn zwischen der Kontaktstelle des Endabschnittes mit dem Mittelpol der Glühlampe und dem sich daran anschließenden deformierten Abschnitt der Leiterbahn federnd abzustützen. Sind der Lampenträger und die daraus ausgestanzten Leiterbahnen auf ein plattenförmiges Gehäuseteil aus Kunststoff aufgelegt, so ist es zweckmäßig, jeden Endabschnitt der Leiterbahnen durch einen an das Gehäuseteil angeformten, vorzugsweise federnd ausgebildeten Arm zu unterstützen. Ein solcher federnder Arm bringt einmal durch seine eigene Elastizität eine Erhöhung der Federkraft und damit eine Erhöhung der Anpreßkraft der Leiterbahnenden an den Glühlampenpol, und zum anderen bildet er einen Stützpunkt, so daß der deformierte Abschnitt der Leiterbahn mehr auf Biegung und weniger auf Torsion beansprucht wird.To change the spring characteristic of the resilient section of the punched-out conductor track, it is expedient to provide resilient support for the end section of the punched-out conductor track between the contact point of the end section with the center pole of the incandescent lamp and the deformed section of the conductor track that follows. If the lamp support and the conductor tracks punched out from it are placed on a plate-shaped housing part made of plastic, it is expedient to support each end section of the conductor tracks by an arm which is preferably resiliently formed on the housing part. Such a resilient arm, on the one hand, brings about an increase in the spring force and thus an increase in the contact force of the conductor track ends against the incandescent lamp pole due to its own elasticity, and on the other hand it forms a support point, so that the deformed section of the conductor track is subjected to more bending and less torsion .

Bei einer vorteilhaften Ausgestaltung des Erfindungsgedankens ist die Federkennlinie des federnden Abschnittes der Leiterbahn zu verbessern, wenn jede Leiterbahn vor dem federnd freien Endabschnitt und dem deformierten Mittelabschnitt eine Materialeinschnürung aufweist, die nicht auf dem plattenförmigen Gehäuseteil aufliegt. Um jeden federnden Endabschnitt der Leiterbahnen biegesteifer zu machen und dadurch den deformierten Abschnitt noch stärker an der Federwirkung zu beteiligen, ist der Endabschnitt profiliert. Er ist im Querschnitt winkel- oder U-förmig ausgebildet.In an advantageous embodiment of the inventive concept, the spring characteristic of the resilient section of the conductor track is to be improved if each conductor track has a material constriction in front of the resilient free end section and the deformed middle section, which does not rest on the plate-shaped housing part. In order to make each resilient end section of the conductor tracks more rigid and thereby to involve the deformed section even more in the spring action, the end section is profiled. It is angular or U-shaped in cross section.

Die in Fig. 1 dargestellte Leuchte besteht im wesentlichen aus einer mehrteiligen Lichtscheibe 1, dem die Leuchte in mehrere Kammern unterteilenden Reflektor 2, dem plattenförmigen Gehäuseteil 3 und dem Lampenträger 5. An das plattenförmige Gehäuseteil 3 sind napfförmige Vertiefungen 4 angeformt, welche die in Fig. 2 bis 9 dargestellten elektrischen Kontakteinrichtungen für die jeweilige Glühlampe aufnehmen.The lamp shown in Fig. 1 consists essentially of a multi-part lens 1, the lamp dividing the lamp into several chambers 2, the plate-shaped housing part 3 and the lamp holder 5. On the plate-shaped housing part 3, cup-shaped depressions 4 are formed, which the in Fig 2 to 9 record electrical contact devices for the respective incandescent lamp.

Aus dem Lampenträger 5 sind Leiterbahnen 6 ausgestanzt, die die elektrischen Zuleitungen für den Mittelpol 7 der Glühlampen 8 bilden. Die Leiterbahnen 9 bilden die Verbindung zwischen den einzelnen Abschnitten 10 des Lampenträgers 5. In die Abschnitte 10 des Lampenträgers 5 sind Öffnungen 11 eingestanzt, in die die Glühlampe 8 mit ihrem Sockel 12 eingesetzt sind. Beim Ausstanzen der Glühlampenöffnung 11 bleiben zwei gegenüberliegende Lappen 13 stehen, die um 90° abgewinkelt sind und den Massekontakt zum Glühlampensockel 12 bilden.Conductor tracks 6 are punched out of the lamp support 5 and form the electrical leads for the center pole 7 of the incandescent lamps 8. The conductor tracks 9 form the connection between the individual sections 10 of the lamp holder 5. Openings 11 are punched into the sections 10 of the lamp holder 5, into which the bulb 8 with its base 12 are inserted. When punching out the bulb opening 11, two opposite tabs 13 remain, which are angled by 90 ° and form the ground contact to the bulb base 12.

Die in Fig. 2, 3 und 4 dargestellte elektrische Zuleitung zum Mittelpol 7 der Glühlampe wird von der Leiterbahn 6 gebildet, die im Bereich der Öffnung 11 zur Aufnahme der Glühlampe Z-förmig verlaufend ausgestanzt und mit ihrem freien Endabschnitt 15 durch Verbiegen des Mittelabschnitts 14 der Z-Form um 180° aus dem Lampenträger 5 herausgeklappt ist. Der Verlauf der Leiterbahn 6 vor dem Abbiegen wird in Fig. 2 durch die strichpunktierte Linie dargestellt. Der Mittelabschnitt 14 der Z-Form ist U-förmig gebogen, so daß der Endabschnitt 15 der Leiterbahn 6 aus der Ebene des Lampenträgers 5 herausgeschwenkt ist. Mit diesem Endabschnitt 15 liegt die Leiterbahn 6 unter Vorspannung an dem Mittelpol 7 der Glühlampe an. Der Endabschnitt 15 ist durch einen an dem plattenförmigen Gehäuseteil 3 angeformten federnden Arm 16 abgestützt. Der Unterstützungspunkt 17 ist zwischen der Kontaktstelle des Endabschnittes 15 mit Mittelpol 7 der Glühlampe und dem U-förmig gebogenen Mittelabschnitt 14 der Z-Form der Leiterbahn 6 angeordnet. Dadurch erhält der Endabschnitt 15 die Wirkung eines doppelarmigen Hebels. Damit diese Wirkung des doppelarmigen Hebels nicht durch Eigenfederung des Endabschnittes 15 vermindert wird, ist dieser durch eine Abwinkelung 18 biegesteifer gemacht. Die Hauptfederung liegt somit in dem federnden und hakenförmig ausgebildeten Arm 16 und in dem U-förmig gebogenen Mittelabschnitt 14 der Z-Form der Leiterbahn 6. Zur Abstimmung der Federkennlinie kann es günstig sein, den auf dem plattenförmigen Gehäuseteil 3 aufliegenden Abschnitt der Leiterbahn 6 mit einer Materialeinschnürung 19 zu versehen. Mit diesem materialschwächeren Teil liegt die Leiterbahn 6 jedoch nicht mehr auf dem plattenförmigen Gehäuseteil 3 auf.The electrical supply line to the center pole 7 of the incandescent lamp shown in FIGS. 2, 3 and 4 is formed by the conductor track 6, which is punched out in a Z shape in the region of the opening 11 for receiving the incandescent lamp and with its free end section 15 by bending the center section 14 the Z-shape is folded out of the lamp holder 5 by 180 °. The course of the conductor track 6 before turning is shown in FIG. 2 by the dash-dotted line. The central section 14 of the Z-shape is bent in a U-shape, so that the end section 15 of the conductor track 6 is pivoted out of the plane of the lamp holder 5. With this end section 15, the conductor track 6 bears against the center pole 7 of the incandescent lamp under pretension. The end section 15 is supported by a resilient arm 16 formed on the plate-shaped housing part 3. The support point 17 is arranged between the contact point of the end section 15 with the center pole 7 of the incandescent lamp and the U-shaped center section 14 of the Z-shape of the conductor track 6. This gives the end section 15 the effect of a double-armed lever. So that this effect of the double-armed lever is not reduced by self-resilience of the end section 15, this is made more resistant to bending by an angle 18. The main suspension is thus in the resilient and hook-shaped arm 16 and in the U-shaped middle section 14 of the Z-shape of the conductor track 6. To adjust the spring characteristic, it can be advantageous to include the section of the conductor track 6 resting on the plate-shaped housing part 3 to provide a material constriction 19. With this weaker part, however, the conductor track 6 no longer lies on the plate-shaped housing part 3.

Die Fig. 5, 6 und 7 zeigen eine andere Ausführungsform des Erfindungsgedankens, die von der vorstehend beschriebenen Ausführungsform im wesentlichen dadurch abweicht, daß durch Einbringen einer Haarnadelfalte 20 in den Mittelabschnitt 14 der freie Endabschnitt der Z-Form in die Mittelebene der Öffnung 11 zur Aufnahme der Glühlampe gebracht .ist und der freie Endabschnitt 15 der Z-Form abgekröpft ist. Der Mittelabschnitt 14 der Z-Form liegt mit seinen beiden Endbereichen auf dem plattenförmigen Gehäuseteil 3 auf. Der freie Endabschnitt 15 verjüngt sich bis zu seinem freien Ende hin, das unter Vorspannung an dem Mittelpol 7 der Glühlampe anliegt. Die Verjüngung des Endabschnittes 15 trägt ebenfalls zu einer günstigen Federkennlinie bei.5, 6 and 7 show another embodiment of the inventive concept, which differs from the embodiment described above essentially in that, by introducing a hairpin fold 20 into the central section 14, the free end section of the Z-shape into the central plane of the opening 11 for Incorporation of the incandescent lamp is brought and the free end portion 15 of the Z-shape is bent. The middle section 14 of the Z-shape lies with its two end regions on the plate-shaped housing part 3. The free end section 15 tapers to its free end, which bears against the center pole 7 of the incandescent lamp under prestress. The tapering of the end section 15 also contributes to a favorable spring characteristic.

Eine weitere Ausführungsform des Erfindungsgedankens zeigen Fig. 8 und 9, die sich von der vorstehend beschriebenen Ausführungsform dadurch unterscheidet, daß der Endabschnitt 15 der Leiterbahn 6 von der Öffnung 11 der Glühlampenöffnung wegweisend verlaufend ausgestanzt ist und in dem Bereich um 180° abgebogen ist. Um die Leiterbahn 6 insbesondere gegenüber einer Torsionsbelastung auf dem plattenförmigen Gehäuseteil 3 befestigen zu können, ist der auf dem Gehäuseteil 3 aufliegende Endbereich der Leiterbahn großflächig ausgeführt. Aus diesem Grunde weist die Leiterbahn einen besonderen nicht der Stromleitung dienenden Schenkel 21 auf, der lediglich der Befestigung dient.A further embodiment of the inventive concept is shown in FIGS. 8 and 9, which differs from the embodiment described above in that the end section 15 of the conductor track 6 is punched out to point away from the opening 11 of the incandescent lamp opening and is bent through 180 ° in the region. In order to be able to fasten the conductor track 6 to the plate-shaped housing part 3, in particular with respect to a torsional load, the end region of the conductor track resting on the housing part 3 has a large area. For this reason, the conductor track has a special leg 21 which does not serve for the power line and which is only used for fastening.
