Abstract

The invention concerns a halogen incandescent lamp mounted without cement, especially one intended for use in a motor vehicle headlight. The lamp according to the invention has a metal holding unit (2) with a recess into which the compressible seal (10) of the lamp tube (1) is securely held by support collars (21a, 21b, 22a, 22b, 23a, 23b). In order to reduce the risk of damage to the compressible seal (10) when the lamp is inserted in the mount, the compressible seal (10) tapers down in steps in the direction of the mount and all the support collars (21a, 21b, 22a, 22b, 23a, 23b) which act on the compressible seal (10) point essentially towards the broad sides of the compressible seal (10) which is substantially rectangular in cross-section, while the narrow sides of the compressible seal (10) are arranged without contact in the support element (2).

Description

Kittlos gesockelte HalogenglühlampeHalogen light bulb with no cement
Die Erfindung betrifft eine kittlos gesockelte Halogenglühlampe gemäß dem Oberbe¬ griff des Patentanspruchs 1.The invention relates to a halogen incandescent lamp without a cement, according to the preamble of claim 1.
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 Halo¬ genglühlampe 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 Quetschdich¬ tung aus, der bei der Sockelung der Lampe zu Glasverletzungen an der Quetschdich- tung führen kann. Die auf die Schmalseiten der Quetschdichtung einwirkenden Stütz¬ laschen können, aufgrund ihrer relativ kleinen Auflagefläche und des starken An¬ druckes an die Schmalseiten, sogar eine Spaltung der Quetschdichtung verursachen.A lamp of this type is disclosed, for example, in US Pat. No. 4,492,893. The lamp described here is a halogen bulb with a cementless base for use in a motor vehicle headlight. This lamp has a lamp bulb with a pinch seal having two broad sides and two narrow sides, which is fixed by clamping in a recess in a holder part belonging to the base. The squeeze foot is fastened in the holder part by means of several fastening or support straps, which act both on the broad sides and on the narrow sides of the squeeze seal. Since the thickness of the pinch seal is uniform over its entire length, the support tabs which are clamped on the broad sides of the pinch seal exert strong pressure on the pinch seal, which can lead to glass injuries on the pinch seal when the lamp is socketed. The support tabs acting on the narrow sides of the pinch seal can even cause the pinch seal to split due to their relatively small contact surface and the strong pressure on the narrow sides.
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 cementless halogen lamp with an improved base which significantly reduces the risk of damage to the pinch seal during lamp socket.
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 claim 1. Particularly advantageous embodiments of the invention are described in the subclaims.
Die erfindungsgemäße Halogenglühlampe wird von einem metallischen Halterteil getragen, das Bestandteil des Lampensockels ist. Das Halterteil besitzt eine Ausstan¬ zung, 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 wesenüichen 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 Sockel¬ richtung hin verjüngt ausgebildet, das heißt, daß die Quetschdichtung an ihrem sockelseitigen, freien Ende eine geringere Dicke aufweist als an ihrem sockelabge- wandten 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 ver¬ sehen, die paßgerecht auf jeweils eine Ausnehmung zweier klemmend an den Breitsei¬ ten anliegenden Stützlaschen abgestimmt sind. Diese Stützlaschen erlauben zusammen mit den Führungsstegen eine seitliche Fixierung der Quetschdichtung in dem Halter- teil. 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 Einras¬ ten 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 carried by a metallic holder part which is part of the lamp base. The holder part has a punched-out section in which the pinch seal of the lamp bulb, which has two broad sides and two narrow sides, is fixed in a clamped manner with the aid of support tabs. The support straps are molded onto the holder part and all act on the broad sides of the squeeze seal, which is essentially rectangular in cross section, while the narrow sides of the press seal are arranged in a contactless manner in the recess of the holder part. As a result, the tolerances of the press seal width do not affect the size of the support forces. In addition, the pinch seal of the lamp bulb is tapered in the base direction, that is to say that the pinch seal has a smaller thickness at its base-side free end than at its end facing away from the base. These measures, compared to the prior art, reduce the risk of damage to the pinch seal when it is inserted into the holder part. Advantageously, the broad sides of the pinch seal are each provided with a guide web which runs in the longitudinal direction and parallel to the narrow sides and which are matched to a recess in each case of two support tabs which clamp against the broad sides. Together with the guide bars, these support tabs allow the pinch seal to be fixed laterally in the holder part. The aforementioned support tabs are also designed to be resilient. Their free ends, together with two nose-like elevations protruding from the broad sides of the pinch seal, form a snap lock, which prevents the pinch seal from being pulled out of the holder part after the support tabs snap in behind the tabs. The holder part advantageously has four further support straps, so that both broad sides of the pinch seal have four support or support points in common with the support straps.
Der Lampenkolben ist femer 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 Stützla¬ schen auf und üben einen leichten Druck auf sie aus. Sie ermöglichen im Zusammen¬ spiel mit dem vorgenannten Rastverschluß eine spielfreie axiale Lagefixierung der Quetschdichtung im Halterteil. Das erfindungsgemäße Halterteil besteht vorteilhaf¬ terweise aus Edelstahl und nicht aus Neusilber. Dann kann auf eine die Umwelt belas- tende Vernickelung des Halterteils verzichtet werden.The lamp bulb is also provided with several molded-in depth stops in the transition area to the pinch seal, which are seated on the holder part after the lamp has been installed. These depth stops advantageously lie on four support lugs and exert slight pressure on them. In conjunction with the aforementioned snap lock, they enable the pinch seal to be fixed in the axial position without play in the holder part. The holder part according to the invention advantageously consists of stainless steel and not of nickel silver. Then the nickel-plating of the holder part, which pollutes the environment, can be dispensed with.

The holder part 2 is welded to the adjustment plate 4 by means of welding lugs 13 punched out of the adjustment plate 4 and bent upwards. Within the lamp bulb 1 there are two incandescent filaments 6, 7, each of which is electrically conductively connected to a contact tab 9 via a total of three current leads 8 protruding from the pinch seal 10 and melted into a glass bead 11. One of the filaments 6 is provided with an anti-glare hood 12.
Die zum Verständnis der Erfindung wesentliche Lampenteile sind in den Figuren 2 bis 5 abgebildet. Figur 2 zeigt das Halterteil 2 der erfindungsgemäßen Halogenglühlampe von unten betrachtet. Die Figuren 3 und 4 illustrieren das Zusammenwirken von Quetschdichtung 10 und Halterteil 2. Das Halterteil 2 besitzt eine ausgestanzte Aus¬ sparung 20, in der die Quetschdichtung 10 klemmend fixiert ist. An das Halterteil 2 sind sechs nach unten, das heißt in Richtung der Kontaktfahnen 9, abgewinkelte Stützlaschen 21a, 21b, 22a, 22b, 23a, 23b angeformt, die klemmend an den Breitsei¬ ten der im Querschnitt im wesentlichen rechteckigen Quetschdichtung 10 anliegen. Vier der Stützlaschen 22a, 22b, 23a, 23b sind mittels Sicken, die ihnen im horizontal verlaufenden Abschnitt einen annähernd V-artigen Querschnitt verschaffen, versteift, während die zwei verbleibenden Stützlaschen 21a, 21b jeweils eine etwa mittig ange¬ ordnete Ausnehmung 24a, 24b aufweisen. Diese Ausnehmungen 24a, 24b sind paßge¬ recht auf jeweils einen an die Breitseiten der Quetschdichtung 10 angeformten Füh¬ rungssteg 50a, 50b abgestimmt. Die Führungsstege 50a, 50b verlaufen in Längsrich- tung, das heißt parallel zu den Schmalseiten der Quetschdichtung 10, und sind unge¬ fähr mittig auf den Breitseiten der Quetschdichtung 10 angeordnet. Zu beiden Seiten der Führungsstege 50a, 50b befindet sich jeweils eine nasenartige Erhebung 51a, 52a, 51b, 52b, die ebenfalls an der Quetschdichtung 10 angeformt sind. Die obere Kante dieser nasenartigen Erhebungen 51a, 52a, 51b, 52b bildet zusammen mit den freien Enden der Stützlaschen 21a, 21b einen Rastverschluß. Die Quetschdichtung 10 ist nach unten hin, das heißt in Sockelrichtung, stufenartig verjüngt. Die Dicke der Quetschdichtung 10 beträgt unterhalb der nasenartigen Erhebungen 51a, 52a, 51b, 52b ungefähr 3,4 mm und oberhalb der nasenartigen Erhebungen 51a, 52a, 51b, 52b ca. 3,8 mm. Die Schmalseiten der Quetschdichtung 10 werden von kreisförmig ge- wölbten Kanten 25 der Aussparung 20 im Halterteil 2 berührungslos umschlungen. Die Quetschdichtung 10 ist femer mit vier Tiefenanschlägen 53a, 54a, 53b, 54b aus¬ gestattet, die im Übergangsbereich zum Lampenkolben 1 an die Breitseiten der Quetschdichtung 10 angeformt sind. Diese Tiefenanschläge 53a, 54a, 53b, 54b sitzen nach der Montage auf den Stützlaschen 22a, 22b, 23a, 23b, die wegen ihrer Sicken aus der Deckelfläche des Halterteils 2 herrausragen, auf. The lamp parts essential for understanding the invention are shown in FIGS. 2 to 5. Figure 2 shows the holder part 2 of the halogen incandescent lamp according to the invention viewed from below. FIGS. 3 and 4 illustrate the interaction of the press seal 10 and the holder part 2. The holder part 2 has a punched-out recess 20 in which the press seal 10 is fixed in a clamping manner. Six support brackets 21a, 21b, 22a, 22b, 23a, 23b, which are angled downward, are formed on the holder part 2, that is to say in the direction of the contact lugs 9, and they clamp against the broad sides of the pinch seal 10, which is essentially rectangular in cross section. Four of the support brackets 22a, 22b, 23a, 23b are stiffened by means of beads which give them an approximately V-shaped cross section in the horizontally running section, while the two remaining support tabs 21a, 21b each have an approximately centrally arranged recess 24a, 24b. These recesses 24a, 24b are matched in each case to a guide web 50a, 50b molded onto the broad sides of the pinch seal 10. The guide webs 50a, 50b run in the longitudinal direction, that is to say parallel to the narrow sides of the pinch seal 10, and are arranged approximately centrally on the broad sides of the pinch seal 10. There is a nose-like elevation 51a, 52a, 51b, 52b on each side of the guide webs 50a, 50b, which are also integrally formed on the pinch seal 10. The upper edge of these nose-like elevations 51a, 52a, 51b, 52b forms, together with the free ends of the support tabs 21a, 21b, a snap lock. The pinch seal 10 is tapered downwards, that is to say in the direction of the base. The thickness of the pinch seal 10 is approximately 3.4 mm below the nose-like elevations 51a, 52a, 51b, 52b and about 3.8 mm above the nose-like elevations 51a, 52a, 51b, 52b. The narrow sides of the pinch seal 10 are encircled without contact by circularly curved edges 25 of the cutout 20 in the holder part 2. The pinch seal 10 is also equipped with four depth stops 53a, 54a, 53b, 54b, which are formed on the broad sides of the pinch seal 10 in the transition region to the lamp bulb 1. After installation, these depth stops 53a, 54a, 53b, 54b are seated on the support tabs 22a, 22b, 23a, 23b, which protrude from the cover surface of the holder part 2 because of their beads.
