Description

Technisches GebietTechnical area

Die Erfindung geht aus von einem Fixierring zum Fixieren eines Lampengefäßes in einer Hülse eines Lampensockels.The invention is based on a fixing ring for fixing a lamp vessel in a sleeve of a lamp cap.

Stand der TechnikState of the art

Das Dokument DE 90172248 U1 bezieht sich auf eine kittlos gesockelte elektrische Lampe, bei der ein Lampenkolben in ein Halteelement gesetzt ist und das Halteelement in einer Justierhülse an einem Sockelteil befestigt ist. Zur Herstellung der Baueinheit aus Lampenkolben, Halteelement und Justierhülse wird der Lampenkolben zunächst in das Halteelement eingesetzt und dann die Baueinheit aus Lampenkolben und das Halteelement von der Flanschseite her in die Justierhülse eingeführt und mittels Justierung die Wände exakt axial ausgerichtet. In der ausgerichteten Lage wird das Halteelement mit der Justierhülse mittels Laser verschweißt.The document DE 90172248 U1 refers to a kittlos capped electric lamp, in which a lamp bulb is placed in a holding element and the holding element is mounted in an adjustment sleeve on a base part.

In the aligned position, the holding element is welded to the adjusting sleeve by means of laser.

Ein derartiges Herstellungsverfahren wird auch bei Lampen nach ECE H8, H9, H11 angewendet. Dadurch, dass die Justierhülse über den im Fixierring bereits geklemmten Brenner geführt wird, schiebt sich diese praktisch von selbst über den Fixierring. Von Nachteil ist dabei, dass die Justierhülse nach dem genannten Stand der Technik vor dem Einführen des Fixierrings mit den anderen Sockelteilen nicht verschweißt sein darf.Such a manufacturing process is also applied to lamps according to ECE H8, H9, H11. Because the adjusting sleeve is guided over the burner already clamped in the fixing ring, it pushes itself practically over the fixing ring. The disadvantage here is that the adjustment sleeve may not be welded according to the cited prior art prior to insertion of the fixing ring with the other base parts.

Darstellung der ErfindungPresentation of the invention

Die Aufgabe der vorliegenden Erfindung ist es, einen Fixierring vorzusehen, mit dem eine gute Fädelbarkeit auf der Fertigungslinie und eine Kostenreduzierung umsetzbar sind.The object of the present invention is to provide a fixing ring with which a good Fädelbarkeit on the production line and a cost reduction can be implemented.

Diese Aufgabe wird durch einen Fixierring nach Anspruch 1 gelöst.This object is achieved by a fixing ring according to claim 1.

Besonders vorteilhafte Ausgestaltungen finden sich in den abhängigen Ansprüchen.Particularly advantageous embodiments can be found in the dependent claims.

Erfindungsgemäß wird ein Fixierring zum Fixieren eines Lampengefäßes an einer Hülse eines Lampensockels vorgesehen. Dabei weist der Fixierring eine Fädelschräge auf, über die Fixierring in der Hülse von der Seite der Lampengefäßes her einbringbar ist. Auf diese Weise kann der Lampensockels einschließlich des Justierhülse vormontiert werden und erst anschließend der Fixierring mit Quetschdichtung des Lampengefäßes eingebracht werden. Dieses gestattet eine stärkere Automatisierung des Herstellungsprozesses des Lampensockels und somit eine Kostenreduzierung beim Herstellungsprozess.According to the invention, a fixing ring for fixing a lamp vessel to a sleeve of a lamp cap is provided. In this case, the fixing ring has a threading slope, can be introduced via the fixing ring in the sleeve from the side of the lamp vessel forth. In this way, the lamp base including the adjusting sleeve can be preassembled and only then the fixing ring with pinch seal of the lamp vessel can be introduced. This allows a greater automation of the manufacturing process of the lamp cap and thus a cost reduction in the manufacturing process.

Entsprechend einer Weiterbildung der Erfindung ist die Fädelschräge einstückig mit dem Fixierring ausgebildet, so dass ein massives Bauteil mit vorteilhaften mechanischen Eigenschaften vorliegt.According to a development of the invention, the threading slope is formed integrally with the fixing ring, so that a solid component with advantageous mechanical properties is present.

Es wird bevorzugt, wenn die Fädelschräge über den gesamten Umfang des Fixierrings ausgebildet ist, so dass ein gleichmäßiges Einfädeln des Fixierrings in die Hülse und eine gleichmäßige Ausrichtung der Lampe in seitlicher Richtung erfolgen kann.It is preferred if the threading bevel is formed over the entire circumference of the fixing ring, so that a uniform threading of the fixing ring into the sleeve and a uniform alignment of the lamp in the lateral direction can take place.

Es wird ferner bevorzugt, dass die Fädelschräge als zwei in Umfangsrichtung beabstandete Abschnitte ausgebildet ist, zwischen denen eine jeweilige Aussparung vorgesehen ist. In dieser Aussparung kann sich beim Herstellungsprozess eine Streifenanbindung befinden, so dass das Halten des Fixierrings während des Herstellungsprozesses über diese Streifenanbindung einfach gestaltet werden kann. Besonders vorteilhaft umfasst die Fädelschräge deutlich mehr als zwei entlang des Fixierringumfangs angeordnete Segmente, die einwärts gebogen sind, so dass der Fixierring im Bereich der Segmente einen reduzierten Außendurchmesser aufweist. Der Abstand zwischen den einzelnen Segmenten der Fädelschräge ist vorteilhafterweise so klein wie möglich, um ein Verhaken der Teile während des Transports und der Montage zu vermeiden.It is further preferred that the Fädelschräge is formed as two circumferentially spaced portions, between which a respective recess is provided. In this recess, a strip connection may be in the manufacturing process, so that the holding of the fixing ring can be made easy during the manufacturing process via this strip connection. Particularly advantageously, the threading slope comprises significantly more than two segments arranged along the fixing ring circumference, which are bent inwards, so that the fixing ring has a reduced outside diameter in the region of the segments. The distance between the individual segments of the threading slope is advantageously as small as possible in order to avoid catching the parts during transport and assembly.

Es ist ferner vorteilhaft, wenn der Fixierring aus einem Stanzstreifen hergestellt wird. Dadurch kann eine Vielzahl an Fixierringen gleichzeitig ausgebildet werden.It is also advantageous if the fixing ring is produced from a stamped strip. As a result, a plurality of fixing rings can be formed simultaneously.

In einer weiteren bevorzugten Ausführungsform weist der Fixierring eine kreisscheibenförmige Deckelfläche auf, in dem ein abgedichtetes Ende des Lampengefäßes verankerbar ist. Dieses gestattet das mittige Einbringen des Lampengefäßes und das gemeinsame Einbringen von Lampengefäß und Fixierring in die Hülse nach dem Fertigstellen des Sockelteils.In a further preferred embodiment, the fixing ring has a circular disk-shaped cover surface, in which a sealed end of the lamp vessel can be anchored. This allows the central introduction of the lamp vessel and the common introduction of lamp vessel and fixing ring in the sleeve after the completion of the base part.

Durch die Ausbildung des Fixierrings in einem Stanzstreifen kann das Ausbilden der Fädelschräge umformtechnisch einfacher gestaltet werden. Insbesondere ist auf Grund der Anordnung des Fixierrings im Stanzstreifen eine exakte Herstellung der Fädelschräge möglich.Due to the design of the fixing ring in a punched strip, the formation of the threading slope can be made simpler in terms of forming technology. In particular, due to the arrangement of the fixing ring in the punching strip an exact production of the threading slope is possible.
