Definitions

  • the invention relates to an electric lamp with a lamp base, which is fastened via a metal cap that engages the lamp pinch foot, is inserted into the base sleeve and is firmly connected to it.
  • the base can have a corresponding number of ground contacts. If there is only one central contact with the ground, the base sleeve must be included as a side contact and the end of the current supply wire in question must be guided between the metal cap and the base sleeve and fixed there.
  • the object of the invention is to ensure an adjustment of the lamp even when the base sleeve has to serve as a side contact and the above measure is necessary for this.
  • the metal cap is smaller in diameter than the minimum diameter of the base sleeve and is provided with an edge groove in which the power supply wire end placed between the metal cap and base sleeve runs.
  • the lamp in FIG. 1 a halogen incandescent lamp, has a lamp bulb 1 made of high-melting glass.
  • a tungsten filament 2 serves as the luminous element.
  • the bulb 1 is filled with inert gas with halogen addition and is closed at the lower end by squeezing.
  • Power supply wires 3 lead through the pinch foot 4 to the outside.
  • a metal cap 5 engages on the pinch foot 4.
  • the pinch foot 4 is received from its opening 6. With inwardly bent tabs 7 (FIG. 3), the metal cap 5 is supported on projections 8 of the crushed glass.
  • the metal cap 5 is cylindrical. Also cylindrical is the lamp base 9, in the metal base sleeve 10 of which the metal cap 5 is inserted with a predetermined play.
  • the base of the sleeve forms a base stone 11 and a central base contact 12.
  • the base sleeve 10 is a side contact. Accordingly, one of the two power supply wires 3 leads to the ground contact 12, the other, however, is guided with its end 3a between the metal cap 5 and the base sleeve 10.
  • the wire end 3a is inserted into an edge groove 13 of the metal cap 5.
  • the edge groove 13 runs approximately parallel to the base axis.
  • Another edge groove 14 is provided which is diametrically opposite the first.

Abstract

Die Metallkappe (5), die am Quetschfuß (4) der Lampe (1) angreift und die Sockelhülse (10) trägt, weist zur Aufnahme eines Stromzuführungsdrahtendes (3a) eine Nut (14) auf, wenn die Sockelhülse (10) elektrischer Seitenkontakt ist. Mit dem Anordnen des Drahtendes (3a) in der Nut (14) wird vermieden, daß durch das Drahtende (3a) das Justieren der zusammen mit ihrer Metallkappe (5) in die Sockelhülse (10) eingesetzten Lampe (1) gegenüber der Sockelhülse (10) behindert ist.The metal cap (5), which engages on the pinch foot (4) of the lamp (1) and carries the base sleeve (10), has a groove (14) for receiving a power supply wire end (3a) when the base sleeve (10) is an electrical side contact . By arranging the wire end (3a) in the groove (14) it is avoided that the wire end (3a) adjusts the lamp (1) inserted into the base sleeve (10) together with its metal cap (5) relative to the base sleeve (10 ) is disabled.

Description

Die Erfindung betrifft eine elektrische Lampe mit einem Lampensockel, der über eine am Lampenquetschfuß angreifende, in die Sockelhülse eingeführte und mit dieser fest verbundenen Metallkappe befestigt ist. Zum elektrischen Anschluß der Lampenstromzuführungsdrähte kann der Sockel eine entsprechende Anzahl Bodenkontakte aufweisen. Bei nur einem zentralen Bodenkontakt ist die Sockelhülse als Seitenkontakt einzubeziehen und das Ende des in Frage kommenden Stromzuführungsdrahtes zwischen Metallkappe und Sockelhülse zu führen und dort festzulegen.The invention relates to an electric lamp with a lamp base, which is fastened via a metal cap that engages the lamp pinch foot, is inserted into the base sleeve and is firmly connected to it. For the electrical connection of the lamp power supply wires, the base can have a corresponding number of ground contacts. If there is only one central contact with the ground, the base sleeve must be included as a side contact and the end of the current supply wire in question must be guided between the metal cap and the base sleeve and fixed there.

Aufgabe der Erfindung ist es, ein Justieren der Lampe auch dann zu gewährleisten, wenn die Sockelhülse als Seitenkontakt zu dienen hat und hierzu die vorstehende Maßnahme erforderlich ist.The object of the invention is to ensure an adjustment of the lamp even when the base sleeve has to serve as a side contact and the above measure is necessary for this.

Die gestellte Aufgabe wird dadurch gelöst, daß die Metallkappe im Durchmesser kleiner als der Mindestdurchmesser der Sockelhülse und mit einer Randnut versehen ist, in der das zwischen Metallkappe und Sockelhülse gelegte Stromzuführungsdrahtende verläuft.The object is achieved in that the metal cap is smaller in diameter than the minimum diameter of the base sleeve and is provided with an edge groove in which the power supply wire end placed between the metal cap and base sleeve runs.

Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels näher beschrieben. Es zeigen

  • Figur 1 eine gesockelte elektrische Lampe
  • Figur 2 die Metallkappe in Draufsicht
  • Figur 3 die Metallkappe im Schnitt.
The invention is described in more detail below using an exemplary embodiment. Show it
  • Figure 1 is a socketed electric lamp
  • Figure 2 shows the metal cap in plan view
  • Figure 3 shows the metal cap in section.

Die Lampe der Figur 1, eine Halogenglühlampe, weist einen Lampenkolben 1 aus hochschmelzendem Glas auf. Als Leuchtkörper dient eine Wolframwendel 2. Der Kolben 1 ist mit Inertgas mit Halogenzusatz gefüllt und am unteren Ende durch Quetschen verschlossen. Stromzuführungsdrähte 3 führen durch den Quetschfuß 4 nach außen. Am Quetschfuß 4 greift eine Metallkappe 5 an. Von ihrer Öffnung 6 ist der Quetschfuß 4 aufgenommen. Mit nach innen gebogenen Lappen 7 (Figur 3) stützt sich die Metallkappe 5 an Vorsprüngen 8 des Quetschungsglases ab. Die Metallkappe 5 ist zylindrisch. Zylindrisch ist auch der Lampensockel 9, in dessen metallische Sockelhülse 10 die Metallkappe 5 mit vorgegebenem Spiel eingeführt ist. Den Hülsenboden bilden Sockelstein 11 und ein zentraler Bodenkontakt 12. Die Sockelhülse 10 ist Seitenkontakt. Entsprechend ist einer der beiden Stromzuführungsdrähte 3 zum Bodenkontakt 12, der andere dagegen mit seinem Ende 3a zwischen Metallkappe 5 und Sockelhülse 10 geführt. Das Drahtende 3a ist eingelegt in eine Randnut 13 der Metallkappe 5. Die Randnut 13 verläuft etwa parallel zur Sockelachse. Eine weitere Randnut 14 ist vorgesehen, die der ersten diametral gegenüberliegt. Nach dem Justieren werden durch Ausnutzen des vorgegebenen Spiels zwischen Metallkappe und Sockelhülse dort die justierte Lampe und der Seitenkontakt mittels Lot 16 ringförmig mit der Sockelhülse 10 verlötet.The lamp in FIG. 1, a halogen incandescent lamp, has a lamp bulb 1 made of high-melting glass. A tungsten filament 2 serves as the luminous element. The bulb 1 is filled with inert gas with halogen addition and is closed at the lower end by squeezing. Power supply wires 3 lead through the pinch foot 4 to the outside. A metal cap 5 engages on the pinch foot 4. The pinch foot 4 is received from its opening 6. With inwardly bent tabs 7 (FIG. 3), the metal cap 5 is supported on projections 8 of the crushed glass. The metal cap 5 is cylindrical. Also cylindrical is the lamp base 9, in the metal base sleeve 10 of which the metal cap 5 is inserted with a predetermined play. The base of the sleeve forms a base stone 11 and a central base contact 12. The base sleeve 10 is a side contact. Accordingly, one of the two power supply wires 3 leads to the ground contact 12, the other, however, is guided with its end 3a between the metal cap 5 and the base sleeve 10. The wire end 3a is inserted into an edge groove 13 of the metal cap 5. The edge groove 13 runs approximately parallel to the base axis. Another edge groove 14 is provided which is diametrically opposite the first. After the adjustment, by using the predetermined play between the metal cap and the base sleeve, the adjusted lamp and the side contact are soldered in an annular manner to the base sleeve 10 by means of solder 16.
