Abstract

The lamp socket consists of a bell-type shaped fixing sleeve (5) of metal and a round plate (6) of plastic. The fixing sleeve carries the lamp, and the round plate secures the fixing sleeve. The round plate has a cylindrical piece (8) with a diameter (d2) which is smaller than the plate diameter (d1). The cylindrical piece (8) has a circumferential slot (9) for holding a sealing washer (10). Flat surfaces which are diametrically opposite one another grip on the upper limit of the slot. The lamp serves for use in motor vehicle headlights. <IMAGE>

Description

Die Erfindung betrifft eine einendig gequetschte Halogenglühlampe mit Kontaktfahnen tragendem Lampensockel aus Metall- und Kunststoffteilen zur Verwendung in Kraftfahrzeugscheinwerfern.The invention relates to a single-ended pinched halogen incandescent lamp base with contact lugs made of metal and plastic parts for use in motor vehicle headlights.

Der Lampensockel ist gemäß den kennzeichnenden Merkmalen des Patentanspruchs gestaltet und ist in der nachfolgenden Beschreibung anhand von Zeichnungen erläutert. Es zeigen

  • Figur 1 die Lampe mit Lampensockel teilweise im Schnitt;
  • Figur 2 die Fixierhülse im Schnitt.
The lamp base is designed in accordance with the characterizing features of the patent claim and is explained in the following description with reference to drawings. Show it
  • Figure 1 shows the lamp with lamp base partially in section;
  • Figure 2 shows the fixing sleeve in section.

Mit 1 ist die Halogenglühlampe, die einen oder mehrere Leuchtkörper 3 aus Wolfram aufweisen kann, mit 2 ist der Lampensockel bezeichnet (Fig. 1). Der Lampenkolben ist aus hochschmelzendem Glas, beispielsweise Hartglas, und ist mit Inertgas mit Halogenzusatz gefüllt. Die Lampe trägt kuppenseitig eine Pumpspitze 4 und ist am anderen Ende durch Quetschen verschlossen. Der Lampensockel 2 ist aufgebaut aus einer glockenartig geformten Fixierhülse 5 aus Metall, beispielsweise Neusilber bzw. Edelstahl, und einem Rundteller 6 aus Kunststoff, geeignet sind beispielsweise Duroplaste, Thermoplaste, der an seiner Unterseite Kontaktfahnen 7 trägt, mit denen die äußeren Stromzuführungen der Lampe elektrischleitend verbunden sind. Die Lampe 1 wird von der Fixierhülse 5 gehalten. Die Lampe ist mit ihrem Quetschteil in die diesem angepaßte Öffnung 5a der Fixierhülse 5 eingesetzt. Die Fixierhülse 5 ist ihrerseits getragen vom Rundteller 6 und aufgesetzt auf ein dem Rundteller 6 mitgegebenem Zylinderstück 8, das einen gegenüber dem Tellerdurchmesser d1 kleineren Durchmesser d2 besitzt. Das Zylinderstück 8 weist eine umlaufende Nut 9 zur Aufnahme eines Dichtungsringes 10, beispielsweise eines Siliconrundschnurringes, auf, wobei die obere Nutbegrenzung, d.h. nahe der Fixierhülse 5, teilweise von diametral gegenüberliegenden angeschliffenen Planflächen übernommen ist, die das lagerichtige Einsetzen der Lampe in den Scheinwerfer sicherstellen.1 is the halogen incandescent lamp, which can have one or more tungsten filaments 3, and 2 is the lamp base (FIG. 1). The lamp bulb is made of high-melting glass, for example hard glass, and is filled with inert gas with halogen addition. The lamp has a pump tip 4 on the dome side and is closed at the other end by squeezing. The lamp base 2 is constructed from a bell-shaped fixing sleeve 5 made of metal, for example nickel silver or stainless steel, and a round plate 6 made of plastic, for example thermosets, thermoplastics, which carry contact tabs 7 on their underside, with which the external power supply leads of the lamp are electrically conductive are connected. The lamp 1 is held by the fixing sleeve 5. The lamp is inserted with its squeezed part into the opening 5a of the fixing sleeve 5 which is adapted to this. The fixing sleeve 5 is in turn worn from the rotary plate 6 and placed on a cylindrical piece 8 given to the rotary plate 6, which has a smaller diameter d 2 than the plate diameter d 1 . The cylinder piece 8 has a circumferential groove 9 for receiving a sealing ring 10, for example a silicone round cord ring, the upper groove boundary, ie close to the fixing sleeve 5, being partially taken over by diametrically opposed ground flat surfaces which ensure the correct insertion of the lamp into the headlight .
