Description

Die Erfindung bezieht sich auf eine elektrische Lampe mit einem hülsenförmigen Sockel, in dem ein zur Aufnahme des Lampenkolbens dienender Innenteil angeordnet ist, der aus einer Deckplatte mit wenigstens zwei an der Innenwand des Sockels anliegenden federnden Laschen besteht, welche mit Öffnungen versehen sind, die mit in den Sockel hineinragenden Gliedern zusammenwirken.The invention relates to an electric lamp with a sleeve-shaped base, in which an inner part for receiving the lamp bulb is arranged, which consists of a cover plate with at least two resilient tabs abutting the inner wall of the base, which are provided with openings which are provided with links protruding into the base.

Bei einer aus der FR-PS 769 029 bekannten Lampe dieser Art weist der Innenteil drei federnde Laschen auf, welche mit relativ großen, langgestreckten Öffnungen versehen sind. Nach dem Einsetzen des Innenteils in den Lampensockel werden hierbei durch Löcher in der Sockelhülse Hohlnieten bis durch die Öffnungen in den Laschen hindurchgesteckt und leicht vernietet, so daß der Innenteil gegenüber dem Sockel noch etwas verstellbar ist, was zum Ausrichten der Lampe benutzt wird. Nach dem Ausrichten werden Sockel und Innenteil miteinander durch Löten oder Schweißen verbunden. Derartige Verbindungen sind aber, insbesondere bei kleinen Lampen, umständlich und teuer. Hinzu kommt noch, daß bei Verwendung dünner Wandstärken das Material bei diesen Behandlungen zerstört werden kann.In a lamp of this type known from FR-PS 769 029, the inner part has three resilient tabs which are provided with relatively large, elongated openings. After inserting the inner part into the lamp base, hollow rivets are inserted through holes in the base sleeve through the openings in the tabs and riveted slightly, so that the inner part is still somewhat adjustable relative to the base, which is used to align the lamp. After alignment, the base and inner part are connected to each other by soldering or welding. However, such connections are cumbersome and expensive, especially in the case of small lamps. In addition, if thin walls are used, the material can be destroyed during these treatments.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Lampe zu schaffen, deren Sockel und Innenteil ohne zusätzliche Wärmebehandlung, wie z.B. Schweißen oder Löten, miteinander verbunden werden können.The invention is therefore based on the object of providing an electric lamp, the base and inner part of which without additional heat treatment, such as e.g. Welding or soldering, can be connected to each other.

Diese Aufgabe wird bei einer elektrischen Lampe eingangs erwähnter Art gemäß der Erfindung dadurch gelöst, daß die in den hülsenförmigen Sockel hineinragenden Glieder als mit dem Sockel fest verbundene Nocken ausgebildet sind, über welche die federnden Laschen beim Einsetzen des Innenteils in den Sockel mit ihren dem Nockenquerschnitt entsprechenden Öffnungen greifen und verriegelnd einrasten.This object is achieved with an electric lamp of the type mentioned at the outset according to the invention in that the members projecting into the sleeve-shaped base as cams are firmly connected to the base, via which the resilient tabs engage with their openings corresponding to the cam cross-section when the inner part is inserted into the base and engage in a locking manner.

Auf diese Weise wird eine rein mechanische Befestigung zwischen Lampensockel und Innenteil sowohl in Drehrichtung als auch in Längsrichtung erreicht.In this way, a purely mechanical attachment between the lamp base and the inner part is achieved both in the direction of rotation and in the longitudinal direction.

Vorzugsweise sind die Nocken als aus der metallenen Sockelhülse nach innen herausgedrückte Vorsprünge ausgebildet. Die Nocken können allerdings auch als am Sockel befestigte, nach innen ragende Stifte ausgebildet sein.The cams are preferably designed as projections pressed out of the metal base sleeve. However, the cams can also be designed as pins which protrude inwards and are fastened to the base.

Um ein Abrutschen der über die Sockelnocken federnd eingerasteten Laschen des Innenteiles und damit ein Lösen des Innenteiles vom Sockel zu vermeiden, weist gemäß einer vorteilhaften Ausführungsform nach der Erfindung der Lampenkolben eine sich bis mindestens auf die Höhe der Nocken in den Sockel hineinerstreckende Quetschung mit im wesentlichen rechteckigem Querschnitt auf, die wenigstens mit einer ihrer schmalen Seitenfläche derart gegenüber einer der federnden Laschen des Innenteiles angeordnet ist, daß ihr Abstand zu dem durch die Laschenöffnung hindurchragenden Nocken kleiner als die Dicke dieser Lasche ist. In diesem Fall muß der Innenteil mit seinen federnden Laschen in den Sockel eingesetzt und dort mit den Nocken verrastet werden, bevor der Lampenkolben im Innenteil befestigt wird.In order to avoid slipping of the tabs of the inner part which are resiliently latched over the base cams and thus detachment of the inner part from the base, according to an advantageous embodiment according to the invention the lamp bulb essentially has a pinch extending into the base with at least the height of the cams rectangular cross-section, which is arranged at least with one of its narrow side surface opposite one of the resilient tabs of the inner part in such a way that its distance from the cam protruding through the tab opening is smaller than the thickness of this tab. In this case, the inner part with its resilient tabs must be inserted into the base and locked there with the cams before the lamp bulb is fastened in the inner part.

Die Lampen nach der Erfindung können in Kraftfahrzeugen verwendbare Glühlampen sein, z.B. Schlußlicht- oder Blinklichtlampen.The lamps according to the invention can be light bulbs which can be used in motor vehicles, e.g. Tail lights or flashing lights.

Zwei Ausführungsbeispiele von Lampen nach der Erfindung werden nunmehr anhand der Zeichnung näher erläutert.Two embodiments of lamps according to the invention will now be explained in more detail with reference to the drawing.

In den Fig. 1 und 2 ist 1 ein z.B. aus Hartglas bestehender Kolben einer kleinen Halogenglühlampe, der an seinem Ende eine im Querschnitt im wesentlichen rechteckige Quetschung 2 aufweist, in welche Stromzuführungsdrähte 3 und 4 zu einer Glühwendel 5 eingebettet sind, deren Enden 6 und 7 aus der Quetschung 2 herausragen.1 and 2, 1 is a e.g. Bulb made of tempered glass of a small halogen incandescent lamp, which at its end has a pinch 2 which is essentially rectangular in cross section, in which current supply wires 3 and 4 are embedded to form a filament 5, the ends 6 and 7 of which protrude from the pinch 2.

Zur Aufnahme des Lampenkolbens 1 ist ein metallischer Innenteil 8 vorgesehen, der aus einer runden Deckplatte 9 mit drei sich rechtwinklig dazu erstreckenden federnden Laschen 10 besteht, die mit jeweils runden Öffnungen 11 versehen sind (Fig. 4 bis 6). Die federnden Laschen 10 sind auf einem Kreis angeordnet, dessen Durchmesser etwa dem Innendurchmesser eines hülsenförmigen Sockels 12 aus Metall entspricht, in den der Innenteil 8 mit seinen federnden Laschen 10 eng passend eingesetzt ist. Hierfür weist der Sockel 12 drei nach innen herausgedrückte Nocken 13 auf, von denen in Fig. 1 nur eine und in Fig. 2 zwei sichtbar sind. Über diese Nocken 13 greifen die federnden Laschen 10 beim Einsetzen des Innenteiles 8 in den Sockel 12 und rasten mit ihren dem Sockelquerschnitt entsprechenden Öffnungen 11 verriegelnd ein. Hierdurch ist der Innenteil 8 mit dem Sockel 12 mechanisch fest verbunden.To accommodate the lamp bulb 1, a metallic inner part 8 is provided, which consists of a round cover plate 9 with three resilient tabs 10 extending at right angles thereto, which are each provided with round openings 11 (FIGS. 4 to 6). The resilient tabs 10 are arranged on a circle, the diameter of which corresponds approximately to the inside diameter of a sleeve-shaped base 12 made of metal, into which the inner part 8 with its resilient tabs 10 is inserted in a closely fitting manner. For this purpose, the base 12 has three inwardly pressed cams 13, of which only one is visible in FIG. 1 and two in FIG. 2. Via these cams 13, the resilient tabs 10 engage when inserting the inner part 8 into the base 12 and engage with their openings 11 corresponding to the base cross section in a locking manner. As a result, the inner part 8 is mechanically firmly connected to the base 12.

Anschließend wird der Lampenkolben 1 in die Deckplatte 9 des Innenteiles 8 eingesetzt. Hierfür sind aus der Deckplatte 9 zwei Haltelaschen 14 schräg nach innen abgebogen. In die so entstandene Öffnung 15 der Deckplatte 9 ist die Quetschung 2 bis zum Anschlag an den Kolben 1 klemmend eingesetzt. Die Quetschung 2 weist auf ihren beiden Längsseiten sich quer zur Lampenlängsachse erstreckende Ansätze 16 auf, hinter welche die zunächst durch die Quetschung 2 auseinandergedrückten, schräg abgebogenen Haltelaschen'14 des Innenteiles 8 beim Einsetzen des Lampenkolbens 1 einrasten, wodurch der Lampenkolben 1 auch in axialer Richtung gegenüber dem Innenteil 8 gesichert ist (vgl. z.B. DE-GM 7 526 777 bzw. US-PS 4 119 877). Damit die in der Endstellung des Innenteiles 8 im Sockel 12 über die Nocken 13 gefederten Laschen 10 nicht wieder aus den Nocken 13 ausrasten können, ist die sich bis mindestens auf die Höhe der Nocken 13 im Sockel 12 erstreckende Quetschung 2 und damit die Öffnung 15 in der Deckplatte 9 des Innenteiles 8 so angeordnet,-daß die Quetschung 2 mit einer ihrer schmalen Seitenfläche 17 derart gegenüber einer der federnden Laschen 10 des Innenteiles 8 liegt, daß ihr Abstand zu dem durch die Laschenöffnung 11 hindurchragenden Nocken 13 kleiner als die Dicke dieser Lasche 10 ist (Fig. 6).The lamp bulb 1 is then inserted into the cover plate 9 of the inner part 8. For this purpose, two retaining tabs 14 are bent obliquely inwards from the cover plate 9. In the resulting opening 15 of the cover plate 9, the pinch 2 is inserted until it stops against the piston 1. The pinch 2 has, on its two longitudinal sides, lugs 16 which extend transversely to the longitudinal axis of the lamp, behind which the holding tabs 14 of the inner part 8, which are initially pressed apart by the pinch 2, snap into place when the lamp bulb 1 is inserted, as a result of which the lamp bulb 1 also engages is secured in the axial direction with respect to the inner part 8 (cf., for example, DE-GM 7 526 777 or US Pat. No. 4,119,877). So that the tabs 10 spring-loaded in the end position of the inner part 8 in the base 12 via the cams 13 cannot disengage from the cams 13, the pinch 2 extending to at least the height of the cams 13 in the base 12 and thus the opening 15 in the cover plate 9 of the inner part 8 arranged so that the pinch 2 with one of its narrow side surfaces 17 lies opposite one of the resilient tabs 10 of the inner part 8 in such a way that its distance from the cam 13 projecting through the tab opening 11 is smaller than the thickness of this tab 10 (Fig. 6).

Anschließend werden die Enden 6 und 7 der Stromzuführungsdrähte 3 und 4 mit den Sockelkontakten 18 und 19 verlötet.Then the ends 6 and 7 of the power supply wires 3 and 4 are soldered to the base contacts 18 and 19.

Die Fig. 7 bis 12 zeigen eine Ausführungsform einer erfindungsgemäßen Lampe, bei welcher der Innenteil 8 lediglich mit zwei federnden Laschen 10 versehen ist, die mit zwei Sockelnocken 13 zusammenwirken. Gleiche Teile haben dieselben Bezugszeichen wie in den Fig. 1 bis 6 erhalten. Wie insbesondere aus Fig. 12 hervorgeht, liegt hierbei die Quetschung 2 mit ihren beiden schmalen Seitenflächen 17 jeweils gegenüber einer der federnden Laschen 10 des Innenteiles 8.7 to 12 show an embodiment of a lamp according to the invention, in which the inner part 8 is only provided with two resilient tabs 10 which cooperate with two base cams 13. The same parts have the same reference numerals as in FIGS. 1 to 6. As can be seen in particular from FIG. 12, the pinch 2, with its two narrow side faces 17, lies opposite each of the resilient tabs 10 of the inner part 8.

Die aus der Deckplatte 9 herausgedrückten Haltelaschen 14 sind rechtwinklig abgebogen; ihr gegenseitiger Abstand entspricht der Breite der Quetschung 2, die in die Öffnung 15 der Deckplatte 9 wiederum bis zum Anschlag an den Kolben 1 klemmend eingesetzt ist. Die Enden 6 und 7 der Stromzuführungsdrähte 3 und 4 sind in gespanntem Zustand mit den Sockelkontakten 18 und 19 verbunden, wodurch der Lampenkolben 1 in axialer Richtung zusätzlich gesichert wird.The holding tabs 14 pushed out of the cover plate 9 are bent at right angles; their mutual distance corresponds to the width of the pinch 2, which is in turn inserted into the opening 15 of the cover plate 9 until it stops against the piston 1. The ends 6 and 7 of the power supply wires 3 and 4 are connected in the tensioned state to the base contacts 18 and 19, whereby the lamp bulb 1 is additionally secured in the axial direction.
