Description
Die Erfindung betrifft eine kittlos gesockelte Halogenglühlampe gemäß dem Oberbegriff
des Patentanspruchs 1.The invention relates to a cementless halogen lamp according to the preamble
of
Eine derartige Lampe ist beispielsweise in der Patentschrift US 4,492,893 offenbart. Bei der hier beschriebenen Lampe handelt es sich um eine kittlos gesockelte Halogenglühlampe zur Verwendung in einem Kfz-Scheinwerfer. Diese Lampe besitzt einen Lampenkolben mit einer zwei Breitseiten und zwei Schmalseiten aufweisenden Quetschdichtung, die in einer Aussparung eines zum Sockel gehörenden Halterteils klemmend fixiert ist. Die Befestigung des Quetschfußes im Halterteil erfolgt mittels mehrerer Befestigungs- oder Stützlaschen, die sowohl auf die Breitseiten als auch, auf die Schmalseiten der Quetschdichtung einwirken. Da die Dicke der Quetschdichtung über ihre gesamte Länge einheitlich ist, üben die klemmend an den Breitseiten der Quetschdichtung anliegenden Stützlaschen einen starken Druck auf die Quetschdichtung aus, der bei der Sockelung der Lampe zu Glasverletzungen an der Quetschdichtung fuhren kann. Die auf die Schmalseiten der Quetschdichtung einwirkenden Stützlaschen können, aufgrund ihrer relativ kleinen Auflagefläche und des starken Andruckes an die Schmalseiten, sogar eine Spaltung der Quetschdichtung verursachen.Such a lamp is disclosed, for example, in US Pat. No. 4,492,893. The lamp described here is a halogen incandescent lamp without a cement for use in an automotive headlamp. This lamp has one Lamp bulb with a two broad sides and two narrow sides Crimp seal, which is in a recess of a holder part belonging to the base is clamped fixed. The squeeze foot is fastened in the holder part by means of several fastening or support straps, both on the broad sides and on the narrow sides of the press seal act. Because the thickness of the press seal Is uniform over their entire length, the practice clamping on the broad sides of the Crimp seal adjacent support tabs a strong pressure on the crimp seal from the lamp socket causing glass injuries to the pinch seal can lead. The support straps acting on the narrow sides of the press seal can, due to their relatively small contact area and the strong pressure on the narrow sides, even cause the pinch seal to split.
Es ist die Aufgabe der Erfindung, eine kittlos gesockelte Halogenglühlampe mit einem verbesserten Sockel bereitzustellen, der während derSockelung der Lampe das Risiko einer Beschädigung der Quetschdichtung erheblich vermindert.It is the object of the invention to provide a halogen lamp with a cementless base to provide an improved base, the risk during the base of the lamp damage to the pinch seal is significantly reduced.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des
Patentanspruchs 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in
den Unteransprüchen beschrieben.This object is achieved by the characterizing features of
Die erfindungsgemäße Halogenglühlampe wird von einem metallischen Halterteil getragen, das Bestandteil des Lampensockels ist. Das Halterteil besitzt eine Ausstanzung, in der die zwei Breitseiten und zwei Schmalseiten aufweisende Quetschdichtung des Lampenkolbens mit Hilfe von Stützlaschen klemmend fixiert ist. Die Stützlaschen sind an das Halterteil angeformt und wirken alle auf die Breitseiten der im Querschnitt im wesentlichen rechteckigen Quetschdichtung ein, während die Schmalseiten der Quetschdichtung berührungsfrei in der Aussparung des Halterteils angeordnet sind. Dadurch gehen die Toleranzen der Quetschdichtungsbreite nicht in die Größe der Abstützkräfte ein. Zusätzlich ist die Quetschdichtung des Lampenkolbens in Sockelrichtung hin verjüngt ausgebildet, das heißt, daß die Quetschdichtung an ihrem sockelseitigen, freien Ende eine geringere Dicke aufweist als an ihrem sockelabgewandten Ende. Durch diese Maßnahmen wird, im Vergleich zum Stand der Technik, die Gefahr einer Beschädigung der Quetschdichtung beim Einsetzen in das Halterteil verringert. Vorteilhafterweise sind die Breitseiten der Quetschdichtung jeweils mit einem in längsrichtung, parallel zu den Schmalseiten verlaufenden Führungssteg versehen, die paßgerecht auf jeweils eine Ausnehmung zweier klemmend an den Breitseiten anliegenden Stützlaschen abgestimmt sind. Diese Stützlaschen erlauben zusammen mit den Führungsstegen eine seitliche Fixierung der Quetschdichtung in dem Halterteil. Die vorgenannten Stützlaschen sind ausserdem federnd ausgebildet. Ihre freien Enden bilden zusammen mit jeweils zwei von den Breitseiten der Quetschdichtung emporragenden, nasenartigen Erhebungen einen Rastverschluß, der, nach dem Einrasten der Stützlaschen hinter den Rastnasen, ein Herausziehen der Quetschdichtung aus dem Halterteil verhindert. Das Halterteil besitzt vorteilhafterweise noch vier weitere Stützlaschen, so daß beide Breitseiten der Quetschdichtung mit den Stützlaschen jeweils vier Auflage- bzw. Abstützungspunkte gemeinsam haben.The halogen incandescent lamp according to the invention is made of a metallic holder part worn, which is part of the lamp base. The holder part has a cutout, in the press seal with the two broad sides and two narrow sides the lamp bulb is clamped with the help of support tabs. The support straps are molded onto the holder part and all act on the broad sides of the cross section a substantially rectangular pinch seal, while the narrow sides of the Pinch seal are arranged in the recess of the holder part without contact. As a result, the tolerances of the press seal width do not go into the size of the Support forces. In addition, the pinch seal of the lamp bulb is in the direction of the base tapered, that is, that the pinch seal on her base-side, free end has a smaller thickness than at its base-facing The End. These measures, compared to the prior art, the risk of damage to the pinch seal when inserted into the holder part decreased. The broad sides of the pinch seal are advantageously each with provided with a guide bar running in the longitudinal direction, parallel to the narrow sides, which fit snugly on one recess of two on the broad sides adjacent support tabs are matched. These support tabs allow together with the guide bars a lateral fixation of the pinch seal in the holder part. The aforementioned support tabs are also designed to be resilient. Your free Ends form together with two of the broad sides of the press seal towering, nose-like elevations a snap lock, which, after snapping the support tabs behind the catches, pulling out the pinch seal the holder part prevented. The holder part advantageously has four more Support tabs so that both broad sides of the pinch seal with the support tabs have four support or support points in common.
Der Lampenkolben ist ferner im Übergangsbereich zur Quetschdichtung mit mehreren angeformten Tiefenanschlägen versehen, die nach der Montage der Lampe auf dem Halterteil aufsitzen. Diese Tiefenanschläge liegen vorteilhafterweise auf vier Stützlaschen auf und üben einen leichten Druck auf sie aus. Sie ermöglichen im Zusammenspiel mit dem vorgenannten Rastverschluß eine spielfreie axiale Lagefixierung der Quetschdichtung im Halterteil. Das erfindungsgemäße Halterteil besteht vorteilhafterweise aus Edelstahl und nicht aus Neusilber. Dann kann auf eine die Umwelt belastende Vemickelung des Halterteils verzichtet werden.The lamp bulb is also in the transition area to the pinch seal with several molded depth stops provided after mounting the lamp on the Sit on the holder part. These depth stops are advantageously on four support tabs and put a little pressure on them. Together they enable a play-free axial position fixation of the Crimp seal in the holder part. The holder part according to the invention advantageously consists made of stainless steel and not of nickel silver. Then the environment can be polluted Nickeling of the holder part can be dispensed with.
