Die Fig. 1 bis 5 zeigen annähernd im Maßstab 1:1 eine Glühlampe 1, die in einem Glühlampenhalter 2 aufgenommen ist. Die Glühlampe 1 ist vorteilhaft eine HiPer-Glühlampe (High Performance-Glühlampe), die bekannt ist und daher auch nicht näher beschrieben wird und sich durch eine hohe Lebensdauer auszeichnet. Diese Glühlampe 1 hat einen Sockel 3, mit dem die Glühlampe 1 in den Glühlampenhalter 2 in noch zu beschreibender Weise gesteckt wird. Über den Sockel 3 ragen zwei Kontaktstifte 4, über welche die Stromversorgung erfolgt. An diese Kontaktstifte 4 sind Verlängerungsstifte 5 angesetzt, die vorteilhaft durch Laserschweißen an die Kontaktstifte 4 angeschweißt werden. Vorteilhaft haben die Kontaktstifte 4 und die Verlängerungsstifte 5 gleichen Durchmesser (Fig. 6 bis 8). Die Verlängerungsstifte 5 sind vorteilhaft sogenannte MQS-Stifte, die einen viereckigen Querschnitt haben.FIGS. 1 to 5 show, approximately on a scale of 1: 1, an incandescent lamp 1, which is accommodated in a bulb holder 2. The incandescent lamp 1 is advantageously a HiPer incandescent lamp (high-performance incandescent lamp), which is known and therefore also not described in detail and is characterized by a long service life. This bulb 1 has a base 3, with which the bulb 1 is inserted into the bulb holder 2 in a manner to be described. About the base 3 protrude two pins 4, via which the power is supplied. At these pins 4 extension pins 5 are attached, which are advantageously welded by laser welding to the contact pins 4. Advantageously, the contact pins 4 and the extension pins 5 have the same diameter (FIGS. 6 to 8). The extension pins 5 are advantageously so-called MQS pins, which have a quadrangular cross-section.

Der Sockel 3 ist etwa in halber Höhe außenseitig mit einem umlaufenden ringförmigen Vorsprung 6 versehen, der in Einbaulage der Glühlampe 1 von Rastzungen 7 des Glühlampenhalters 2 übergriffen wird (Fig. 7 und 8). Der Vorsprung 6 befindet sich in Höhe einer radialen Ringschulterfläche 8, mit der der Sockel 3 auf einer Anlagefläche 9 des Glühlampenhalters 2 aufliegt (Fig. 6 und 9). An die ebene Ringschulterfläche 8 schließt ein im Durchmesser verringerter Endabschnitt 10 an, der eine ebene Stirnseite 11 aufweist. Über sie stehen die Kontaktstifte 4 über.The base 3 is provided at about half the height on the outside with a circumferential annular projection 6 which is overlapped in the installed position of the bulb 1 by locking tongues 7 of the bulb holder 2 (FIGS. 7 and 8). The projection 6 is located at the level of a radial annular shoulder surface 8, with which the base 3 rests on a contact surface 9 of the bulb holder 2 (FIGS. 6 and 9). To the flat annular shoulder surface 8 includes a reduced diameter end portion 10, which has a flat end face 11. About them are the pins 4 over.

Der Glühlampenhalter 2 hat ein Gehäuse 12, das im Ausführungsbeispiel ovalen Umriß aufweist. Das Gehäuse 12 ist an seinem von der Glühlampe 1 abgewandten Ende offen. Mit diesem offenen Ende wird das Gehäuse 12 auf einen (nicht dargestellten) herkömmlichen Verbinder gesteckt, über den die Leuchteinheit an eine Strom/Spannungsquelle angeschlossen ist. Dieser Verbinder liegt an der Innenwand des Gehäuses 12 an und nimmt die Verlängerungsstifte 5 auf. Je nach Ausbildung des Verbinders kann das Gehäuse 12 auch einen entsprechend anderen Umriß haben.The incandescent lamp holder 2 has a housing 12 which has an oval outline in the exemplary embodiment. The housing 12 is open at its end remote from the incandescent lamp 1. With this open end, the housing 12 is plugged onto a conventional connector (not shown) through which the light unit is connected to a power source. This connector abuts against the inner wall of the housing 12 and receives the extension pins 5. Depending on the design of the connector, the housing 12 may also have a correspondingly different outline.

Das Gehäuse 12 ist an seinem der Glühlampe 1 zugewandten Ende durch einen Boden 13 geschlossen, der zwei Durchtrittsöffnungen 14, 15 für die Verlängerungsstifte 5 aufweist. Die Durchtrittsöffnungen 14, 15 sind gleich ausgebildet und haben einen kegelförmigen Einführungsabschnitt 16, 17, der in einen zylindrischen Abschnitt 18, 19 übergeht. Die Einführungsabschnitte 16, 17 verjüngen sich in Richtung auf die zylindrischen Abschnitte 18, 19. Aufgrund der kegelförmigen Einführungsabschnitte 16, 17 können die Verlängerungsstifte 5 beim Einsetzen der Glühlampe 1 in den Glühlampenhalter 2 sicher in die Durchtrittsöffnungen 14, 15 gelangen.The housing 12 is closed at its end facing the incandescent lamp 1 by a bottom 13, which has two passage openings 14, 15 for the extension pins 5. The passage openings 14, 15 are of identical design and have a conical insertion section 16, 17, which merges into a cylindrical section 18, 19. The insertion portions 16, 17 taper in the direction of the cylindrical portions 18, 19. Due to the tapered insertion portions 16, 17, the extension pins 5 when inserting the light bulb 1 in the incandescent holder 2 safely pass into the passage openings 14, 15.

In Höhe des Bodens 13 ist der Glühlampenhalter 2 mit einem radial nach außen ragenden umlaufenden Flansch 20 versehen, von dem über den Umfang verteilt mehrere Rastzungen 7 abstehen. Im Ausführungsbeispiel sind vier Rastzungen 7 vorgesehen, die gleichmäßig verteilt über den Umfang des Flansches 20 vorgesehen sind und radialen Abstand von den Durchtrittsöffnungen 14, 15 haben. Auf dem Flansch 20 liegt ein Dichtring 21 auf, der gleichen Außendurchmesser wie der Flansch 20 hat und mit seinem radial inneren Rand in eine Ringnut 22 eingreift, die am äußeren Umfang eines ringförmigen Vorsprunges 23 vorgesehen ist. Von ihm stehen die Rastzungen 7 etwa vertikal ab. Zwei diametral einander gegenüberliegende Rastzungen sind am freien Ende mit einem radial nach außen ragenden Flansch 24 versehen, der sich über die Umfangslänge dieser Rastzungen 7 erstreckt, die Teil eines Bajonettverschlusses sind, mit dem der Glühlampenhalter 2 in einer Leuchte montiert werden kann.At the level of the bottom 13 of the bulb holder 2 is provided with a radially outwardly projecting circumferential flange 20, of which distributed over the circumference a plurality of locking tongues 7 protrude. In the exemplary embodiment, four locking tongues 7 are provided, which are distributed uniformly over the circumference of the flange 20 and radial distance from the passage openings 14, 15 have. On the flange 20 is a sealing ring 21 which has the same outer diameter as the flange 20 and engages with its radially inner edge in an annular groove 22 which is provided on the outer circumference of an annular projection 23. From him the locking tongues 7 are about vertically from. Two diametrically opposed locking tongues are provided at the free end with a radially outwardly projecting flange 24 which extends over the circumferential length of these locking tongues 7, which are part of a bayonet fitting, with which the bulb holder 2 can be mounted in a lamp.

Der Glühlampenhalter 2 ist vorteilhaft einstückig ausgebildet, so daß er in einem Arbeitsgang kostengünstig gefertigt werden kann. Der Dichtring 21 besteht vorteilhaft aus einem anderen Material als der Glühlampenhalter 2. Der Glühlampenhalter 2 ist ein Spritzgußteil und besteht beispielsweise aus Polyamid 6.6 mit einem Anteil von 30 % Glasfaser. Der Dichtring 21, der beispielsweise aus einem technischen Elastomer besteht, wird in der Spritzgußform an den Glühlampenhalter 2 angespritzt.The incandescent holder 2 is advantageously integrally formed, so that it can be manufactured inexpensively in one operation. The sealing ring 21 is advantageously made of a different material than the bulb holder 2. The bulb holder 2 is an injection molded part and consists for example of polyamide 6.6 with a share of 30% glass fiber. The sealing ring 21, which consists for example of a technical elastomer, is molded in the injection mold to the bulb holder 2.

Fig. 8 zeigt die Glühlampe 1 vor dem Einsetzen in den Glühlampenhalter 2. Beim Zusammenstecken können die Verlängerungsstifte 5 infolge der konischen Einführungsabschnitte 16, 17 problemlos in die Durchtrittsöffnungen 14, 15 des Glühlampenhalters 2 gesteckt werden. Die Glühlampe 1 wird so weit eingesteckt, bis die Stirnseite 11 des Glühlampensockels 3 auf der Anlagefläche 9 des Glühlampenhalters 2 aufliegt. Beim Einsteckvorgang werden die Rastzungen 7 durch den umlaufenden Vorsprung 6 des Glühlampensockels 3 elastisch nach außen gebogen, bis die an den freien Enden der Rastzungen 7 vorgesehenen Rastvorsprünge den Ringvorsprung 6 des Glühlampensockels 3 übergreifen (Fig. 9). Auf diese Weise sind die Glühlampe 1 und der Glühlampenhalter 2 sicher miteinander verbunden. In dieser verclipsten Lage befindet sich die Schweißstelle 25 zwischen den Kontaktstiften 4 und den Verlängerungsstiften 5 in den Durchtrittsöffnungen 14, 15. Wie Fig. 9 zeigt, liegen die Schweißstellen 25 in den kegelförmigen Einführungsabschnitten 16, 17. Die Verlängerungsstifte 5 sind dadurch in den zylindrischen Abschnitten 18, 19 der Durchtrittsöffnungen 14, 15 einwandfrei geführt und fixiert. Wird der Glühlampenhalter 2 auf den Verbinder aufgesteckt, dann ist durch diese Fixierung und Führung sichergestellt, daß die Verlängerungsstifte 5 in die entsprechenden Stecköffnungen des Verbinders zuverlässig gelangen.Fig. 8 shows the bulb 1 before insertion into the bulb holder 2. When mating the extension pins 5 can be easily inserted into the through holes 14, 15 of the bulb holder 2 due to the conical insertion portions 16, 17. The light bulb 1 is inserted so far until the end face 11 of the light bulb base 3 rests on the contact surface 9 of the bulb holder 2. When inserting the locking tongues 7 are elastically bent by the circumferential projection 6 of the bulb socket 3 outwardly until the provided at the free ends of the locking tongues 7 locking projections engage over the annular projection 6 of the bulb socket 3 (Fig. 9). In this way, the incandescent lamp 1 and the bulb holder 2 are securely connected to each other. In this verclipsten position, the weld 25 is located between the contact pins 4 and the extension pins 5 in the through holes 14, 15. As shown in FIG. 9, the welds 25 are in the tapered insertion portions 16, 17. The extension pins 5 are characterized in the cylindrical Sections 18, 19 of the openings 14, 15 properly guided and fixed. If the bulb holder 2 is attached to the connector, then it is ensured by this fixation and guidance that the extension pins 5 arrive reliably in the corresponding plug openings of the connector.

Die Innenwand 26 des Gehäuses 12 bildet eine Dichtfläche, an welcher der Verbinder dichtend anliegt.The inner wall 26 of the housing 12 forms a sealing surface against which the connector bears in a sealing manner.

Die Leuchteinheit aus Glühlampe 1 und Glühlampenhalter 2 kann im gesamten Automotive-Bereich eingesetzt werden, so als Blinkleuchte, Zusatzblinker, Schlußlicht, Bremslicht, Nebelschlußlicht, Rückfahrlicht, Signallicht, Innenbeleuchtungslicht und dergleichen. Die Glühlampe 1 kann für die jeweils vorhandenen Bordspannungen verwendet werden, so für 12 Volt, 19 Volt oder 24 Volt. Da die Innenwand 26 des Gehäuses 12 als Dichtfläche wirksam ist, ergibt sich eine optimale Wasserdichtheit.The lighting unit of incandescent lamp 1 and incandescent lamp holder 2 can be used throughout the automotive sector, such as flashing light, auxiliary flasher, tail light, brake light, rear fog light, reversing light, signal light, interior lighting light and the like. The bulb 1 can be used for the existing on-board voltages, such as 12 volts, 19 volts or 24 volts. Since the inner wall 26 of the housing 12 is effective as a sealing surface, there is an optimal watertightness.

Der Glühlampenhalter 2 kann aus jedem geeigneten spritzgußfähigen Kunststoff hergestellt werden. Während des Spritzgußverfahrens wird der Dichtring 21 angespritzt.The bulb holder 2 can be made of any suitable injection-moldable plastic. During the injection molding process, the sealing ring 21 is molded.
