Abstract

Bei einer elektrischen Lampe mit einem hülsenförmigen Sockel (15) und einer den Lampenkolben (1) tragenden Innenhülse (9) besitzt der Sockel (15) wenigstens zwei nach innen ragende Nocken (16) und ist die Innenhülse (9) auf ihrem Zylindermantel (12) mit wenigstens zwei schlitzartigen Aussparungen (14) versehen, welche über die Nocken (16) greifen.In the case of an electric lamp with a sleeve-shaped base (15) and an inner sleeve (9) carrying the lamp bulb (1), the base (15) has at least two inwardly projecting cams (16) and is the inner sleeve (9) on its cylinder jacket (12 ) with at least two slot-like recesses (14) which engage over the cams (16).

Description

Die Erfindung bezieht sich auf eine elektrische Lampe mit einem hülsenförmigen Sockel, in dem eine den Lampenkolben tragende zylindrische Innenhülse angeordnet ist.The invention relates to an electric lamp with a sleeve-shaped base, in which a cylindrical inner sleeve carrying the lamp bulb is arranged.

Bei bekannten Lampen dieser Art (z.B. DE-OS 1 489 414 oder FR-PS 769 029) werden Sockel und Innenhülse nach dem Zusammenbau durch Löten oder Schweißen miteinander verbunden. Derartige Verbindungen sind umständlich und teuer. Hinzu kommt noch, daß bei Verwendung dünner Wandstärken das Material beim Punktschweißen zerstört werden kann.In known lamps of this type (e.g. DE-OS 1 489 414 or FR-PS 769 029), the base and the inner sleeve are connected to one another after assembly by soldering or welding. Such connections are cumbersome and expensive. In addition, if thin wall thicknesses are used, the material can be destroyed during spot welding.

Der Erfindung liegt daher die Aufgabe zugrunde, eine elektrische Lampe zu schaffen, deren Sockel und Innenhülse 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 whose base and inner sleeve 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 der hülsenförmige Sockel wenigstens zwei nach innen ragende Nocken aufweist und die Innenhülse auf ihrem Zylindermantel mit wenigstens zwei sich in Lampenachsrichtung bis zu ihrem im Sockelinneren liegenden Rand erstreckenden schlitzartigen Aussparungen versehen ist, welche über die Nocken greifen.This object is achieved in an electric lamp of the type mentioned at the outset according to the invention in that the sleeve-shaped base has at least two inwardly projecting cams and the inner sleeve on its cylinder jacket is provided with at least two slot-like recesses which extend in the lamp axis direction up to its edge lying on the inside of the base is which reach over the cams.

Auf diese Weise wird eine rein mechanische Befestigung zwischen Lampensockel und Innenhülse erreicht.In this way, a purely mechanical attachment between the lamp base and the inner sleeve is achieved.

Vorzugsweise sind die Nocken als aus der metallenen Sockelwand 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 wall forms. However, the cams can also be designed as pins which protrude inwards and are fastened to the base.

Zweckmäßigerweise erweitern sich die schlitzartigen Aussparungen zum Rand hin. Auf diese Weise lassen sich Sockel und Innenhülse leicht zusammensetzen ohne vorherige genaue Ausrichtung beider Teile zueinander.The slot-like cutouts expediently widen towards the edge. In this way, the base and inner sleeve can be easily put together without prior precise alignment of the two parts to one another.

Durch das eng passende Zusammenwirken der schlitzartigen Aussparungen der Innenhülse mit den Sockelnocken sind Sockel und Innenhülse gegen Verdrehung gesichert. Eine Bewegung in axialer Richtung läßt sich in bekannter Weise dadurch vermeiden, daß die aus dem Lampenkolben herausragenden Stromzuführungsdrähte straff gespannt und mit den Sockelkontakten verlötet werden (DE-OS 1 908 641).The closely fitting interaction of the slot-like recesses in the inner sleeve with the base cams ensures that the base and inner sleeve are prevented from rotating. Movement in the axial direction can be avoided in a known manner by tensioning the power supply wires protruding from the lamp bulb and soldering them to the base contacts (DE-OS 1 908 641).

Wenn die Stromzuführungsdrähte, z.B. aus mechanischen Gründen, zur axialen Sicherung zwischen Sockel und Innenhülse nicht geeignet sind, können gemäß einer vorteilhaften Weiterbildung der Lampe nach der Erfindung die schlitzarti-gen Aussparungen mit federnden Laschen versehen sein, die beim Einsetzen der Innenhülse in den Sockel von den Sockelnocken auseinandergedrückt werden und in der Endstellung der Innenhülse hinter die Nocken zurückfedern. Auf diese Weise rasten die federnden Laschen der Innenhülse praktisch hinter die Sockelnocken ein und gewährleisten somit einen festen Sitz der Innenhülse im Sockel auch in axialer Richtung.If the power supply wires, e.g. for mechanical reasons, are not suitable for axial securing between the base and the inner sleeve, according to an advantageous development of the lamp according to the invention, the slot-like recesses can be provided with resilient tabs which are pushed apart by the base cams when the inner sleeve is inserted into the base and spring back behind the cams in the end position of the inner sleeve. In this way, the resilient tabs of the inner sleeve practically snap into place behind the base cams and thus ensure that the inner sleeve is firmly seated in the base, even in the axial direction.

Die Laschen können z.B. aus nach innen umgebogenen federnden Randteilen des sich an die schlitzartigen Aussparungen anschließenden Zylindermantels der Innenhülse bestehen.The tabs can e.g. consist of inwardly bent resilient edge parts of the cylinder jacket of the inner sleeve adjoining the slot-like recesses.

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.

  • Fig. 10 einen um 90° gedrehten Längsschnitt durch die Innenhülse längs der Linie X-X der Fig. 9;
  • Fig. 11 einen Querschnitt durch die Innenhülse längs der Linie XI-XI der Fig. 10.
Two embodiments of lamps according to the invention will now be explained in more detail with reference to the drawing. Show it:
  • 1 shows a longitudinal section through an incandescent lamp, the bulb of which is seated in an inner sleeve which is accommodated in a base;
  • FIG. 2 shows a longitudinal section through the lamp according to FIG. 1 along the line II-II;
  • 3 shows a plan view of the inner sleeve of the lamp according to FIGS. 1 and 2 on an enlarged scale;
  • 4 shows a longitudinal section through the inner sleeve according to FIG. 3 along the line IV-IV;
  • 5 shows a longitudinal section rotated through 90 ° through the inner sleeve along the line VV in FIG. 4;
  • 6 and 7 two longitudinal sections of an incandescent lamp rotated by 90 ° with a different inner sleeve;
  • 8 shows a plan view of the inner sleeve of the lamp according to FIGS. 6 and 7 on an enlarged scale;
  • 9 shows a longitudinal section through the inner sleeve according to FIG. 8 along the line IX-IX;
  • 10 shows a longitudinal section rotated through 90 ° through the inner sleeve along the line XX of FIG. 9;
  • 11 is a cross section through the inner sleeve along the line XI-XI of FIG. 10th

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 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. Piston made of tempered glass of a small halogen incandescent lamp, which has at its end a squeeze 2 with a rectangular 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 squeeze 2.

Der Lampenkolben 1 ist mit seiner Quetschung 2 in einer Deckplatte 8 einer metallischen Innenhülse 9 gehaltert (Fig. 3 bis 5). Hierfür sind aus der Deckplatte 8 zwei Haltelaschen 10 rechtwinklig herausgedrückt, deren Abstand der Breite der Quetschung 2 entspricht. In die so entstandene Öffnung 11 der Deckplatte 8 ist die Quetschung 2 bis zum Anschlag an den Kolben 1 klemmend eingesetzt.The lamp bulb 1 is held with its pinch 2 in a cover plate 8 of a metallic inner sleeve 9 (Fig. 3 to 5). For this purpose, two retaining tabs 10 are pressed out of the cover plate 8 at right angles, the spacing of which corresponds to the width of the pinch 2. In the opening 11 of the cover plate 8 thus created, the pinch 2 is inserted until it stops against the piston 1.

Die Innenhülse 9 ist auf ihrem Zylindermantel 12 mit zwei sich in Lampenachsrichtung bis zu ihrem im Sockelinneren liegenden Rand 13 erstreckenden schlitzartigen Aussparungen 14 versehen, welche sich zum Rand 13 hin erweitern.The inner sleeve 9 is provided on its cylinder jacket 12 with two slot-like recesses 14 which extend in the lamp axis direction up to its edge 13 lying inside the base and which widen towards the edge 13.

Die Innenhülse 9 ist eng passend in einem hülsenförmigen Sockel 15 aus Metall angeordnet. Hierfür weist der Sockel 15 zwei nach innen herausgedrückte Nocken 16 auf, über welche die schlitzartigen Aussparungen 14 der Innenhülse 9 bei deren Einsetzen in den Sockel 15 greifen. Hierdurch sind der Sockel 15 und die Innenhülse 9 einander gegenüber gegen Verdrehung gesichert. Die Innenhülse 9 wird so weit in den Sockel 15 eingeschoben, bis die Sockelnocken 16 an das Ende der schlitzartigen Aussparungen 14 im Zylindermantel 12 der Innenhülse 9 anstoßen. Anschließend werden die Enden 6 und 7 der Stromzuführungsdrähte 3 und 4 in straff gespanntem Zustand mit den Sockelkontakten 17 und 18 verlötet, wodurch die Innenhülse 9 im Sockel 15 auch in axialer Richtung gesichert wird.The inner sleeve 9 is closely fitted in a sleeve-shaped base 15 made of metal. For this purpose, the base 15 has two inwardly pressed cams 16, via which the slot-like recesses 14 of the inner sleeve 9 engage when they are inserted into the base 15. As a result, the base 15 and the inner sleeve 9 are secured against rotation relative to one another. The inner sleeve 9 is pushed into the base 15 until the base cams 16 abut the end of the slot-like recesses 14 in the cylinder jacket 12 of the inner sleeve 9. The ends 6 and 7 of the power supply wires 3 and 4 are then soldered to the base contacts 17 and 18 in a tightly tensioned state, as a result of which the inner sleeve 9 is also secured in the base 15 in the axial direction.

Die Fig. 6 bis 11 zeigen eine Ausführungsform einer erfindungsgemäßen Lampe, bei der die axiale Sicherung der Innenhülse im Lampensockel andersartig erfolgt. Gleiche Teile haben dieselben Bezugszeichen wie in den Fig. 1 bis 5 erhalten. Bei dieser Ausführungsform sind jedoch in der Deckplatte 8 der Innenhülse 9 die Haltelaschen 10 nicht rechtwinklig, sondern nur schräg nach innen abgebogen. Die Quetschung 2 des Lampenkolbens 1 weist auf ihren beiden Längsseiten sich quer zur Lampenlängsachse erstreckende Ansätze 19 auf, hinter welche die schräg abgebogenen Haltelaschen 10 der Innenhülse 9 beim Einsetzen des Lampenkolbens 1 verriegelnd einrasten (vgl. z.B. DE-GM 7 526 777 oder US-PS 4 119 877).6 to 11 show an embodiment of a lamp according to the invention, in which the axial securing of the inner sleeve in the lamp base takes place differently. The same parts have the same reference numerals as in FIGS. 1 to 5. In this embodiment, however, the retaining tabs 10 in the cover plate 8 of the inner sleeve 9 are not bent at right angles, but rather are only bent obliquely inwards. The pinch 2 of the lamp bulb 1 has, on its two longitudinal sides, extensions 19 which extend transversely to the longitudinal axis of the lamp, behind which the obliquely bent retaining tabs 10 of the inner sleeve 9 latch in a locking manner when the lamp bulb 1 is inserted (cf., for example, DE-GM 7 526 777 or US Pat. PS 4 119 877).

Die Innenhülse 9 ist wiederum mit schlitzartigen Aussparungen 24 versehen, die sich bis zum Rand 13 des Zylindermantels 12 der Innenhülse 9 erstrecken. Die schlitzartigen Aussparungen 24 weisen hierbei aber in ihrem mittleren Bereich nach innen ragende federnde Laschen 20 auf, welche aus nach innen umgebogenen Randteilen des sich an die schlitzartigen Aussparungen 24 anschließenden Zylindermantels 12 der Innenhülse 9 bestehen. Diese federnden Laschen 20 verringern die Breite der Aussparungen 24 etwas, werden aber beim Einsetzen der Innenhülse 9 in den hülsenförmigen Sockel 15 von deren Nocken 16 auseinandergedrückt und federn in der Endstellung der Innenhülse 9 hinter die Nocken 16 zurück, wodurch eine axiale Sicherung der Innenhülse 9 im Sockel 15 erreicht wird (Fig. 7).The inner sleeve 9 is in turn provided with slot-like recesses 24 which extend to the edge 13 of the cylinder jacket 12 of the inner sleeve 9. However, the slot-like recesses 24 have in their central region inwardly projecting resilient tabs 20 which consist of inwardly bent edge parts of the cylinder jacket 12 of the inner sleeve 9 adjoining the slot-like recesses 24. These resilient tabs 20 slightly reduce the width of the cutouts 24, but are pushed apart by the cams 16 when the inner sleeve 9 is inserted into the sleeve-shaped base 15 and spring back in the end position of the inner sleeve 9 behind the cams 16, thereby axially securing the inner sleeve 9 is reached in the base 15 (Fig. 7).
