Description

Die Erfindung bezieht sich auf eine Lampenfassung zur Aufnahme einer Glassockellampe gemäß dem Oberbegriff des Anspruches 1.The invention relates to a lamp holder for receiving a glass base lamp according to the preamble of claim 1.

Als Stand der Technik wird von einer Lampenfassung ausgegangen (FR-A-2 356 292), bei welcher eine Außenhülse und ein Innentrennbereich als einstückige Einheit ausgebildet sind, die die Kontaktelemente voneinander isoliert. Diese Kontaktelemente sind kostenaufwendig aus Blech gefertigt und müssen mit erhöhtem Montageaufwand im Inneren der Lampenfassung angeordnet werden.The prior art is based on a lamp holder (FR-A-2 356 292), in which an outer sleeve and an inner separating area are formed as a one-piece unit which isolates the contact elements from one another. These contact elements are costly made of sheet metal and have to be arranged inside the lamp socket with increased assembly effort.

Weitere Lampenfassungen (DE-AS 14 64 176, DE-AS 23 10 151) sind so aufgebaut, daß innerhalb einer Hülse wiederum aus Blech bestehende Führungen angeordnet sind, welche sowohl Federelemente als auch Kurvenbahnen aufweisen. Auch hieraus ergibt sich ein erheblicher Montage- und Kostenaufwand zur Herstellung und Anordnung der einzelnen Metallelemente im Inneren einer derartigen Lampenfassung.Other lamp holders (DE-AS 14 64 176, DE-AS 23 10 151) are constructed such that guides made of sheet metal are arranged within a sleeve, which have both spring elements and curved tracks. This also results in considerable assembly and cost expenditure for the production and arrangement of the individual metal elements in the interior of such a lamp holder.

Zum Stand der Technik zählt darüber hinaus elektrisch leitender Kunststoff, welcher einen Gehalt an einer leitfähigen Komponente besitzt und beispielsweise durch Spritzgießen oder Spritzpressen verarbeitet werden kann (DE-A-34 09 953, DE-A-33 05 401, DE-A 32 45 578, DE-A- 32 38 246). Diese elektrisch leitfähigen Kunststoffe können als Verbundkörper eingesetzt werden.The prior art also includes electrically conductive plastic, which contains a conductive component and can be processed, for example, by injection molding or transfer molding (DE-A-34 09 953, DE-A-33 05 401, DE-A 32 45 578, DE-A-32 38 246). These electrically conductive plastics can be used as composite bodies.

Weiterer Stand der Technik ist eine Lampenfassung für Glühbirnen mit freien Drahtenden oder für Leuchtdioden (DE 37 27 515 A1). Hier finden ein Außenrohr sowie ein Innenrohr Anwendung, wobei das freie Drahtende der Glühbirne über eine Klemmhülse am Außenrohr festgeklemmt wird. Zwischen dem Außenrohr und dem Innenrohr ist eine Isolierschicht angeordnet, um das leitende Außenrohr von dem leitenden Innenrohr zu trennen. Beide Rohre sind glatt ausgebildet und bedürfen einer besonderen lagestabilisierenden Verbindung, wobei außerdem die Klemmhülse eine zusätzliche Fixierung erfahren muß.Another prior art is a lamp holder for light bulbs with free wire ends or for light-emitting diodes (DE 37 27 515 A1). An outer tube and an inner tube are used here, the free wire end of the light bulb being clamped to the outer tube by means of a clamping sleeve. An insulating layer is arranged between the outer tube and the inner tube in order to separate the conductive outer tube from the conductive inner tube. Both tubes are smooth and require a special position-stabilizing connection, with the clamping sleeve also having to undergo additional fixation.

Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Lampenfassung der eingangs genannten Art so auszubilden, daß ein einfacher, kostensparender Aufbau geschaffen wird, wobei zudem der Montageaufwand gering gehalten werden soll.In contrast, the present invention has for its object to design a lamp holder of the type mentioned in such a way that a simple, cost-saving structure is created, and in addition, the assembly effort should be kept low.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen im kennzeichnenden Teil des Anspruchs 1 gelöst. Dadurch, daß beide Kontaktelemente jeweils aus einem elektrisch leitfähigem Kunststoffmaterial bestehen und die Fassung eine die Kontaktelemente umschließende Außenhülse und eine dem Inneren der Fassung angeordneten, die Kontaktelemente voneinander isolierenden Innentrennbereich aufweist, entfällt die kostenintensive und bauaufwendige Herstellung der aus Metall bestehenden Kontaktelemente.This object is achieved with the features in the characterizing part of claim 1. The fact that both contact elements each consist of an electrically conductive plastic material and the socket has an outer sleeve enclosing the contact elements and an inner separating region arranged inside the socket and isolating the contact elements from one another, eliminates the cost-intensive and expensive manufacture of the contact elements made of metal.

In den Ausführungsform nach Anspruch 1 können hierbei die Außenhülse und der Innentrennbereich als einstückige Einheit ausgebildet sein, wobei die Kontaktelemente gleichfalls hülsenartig ausgebildet sind und sich in den Zwischenraum zwischen der Außenhülse und dem Innentrennbereich und in den Innenraum des Innenbereichs einsetzen lassen. In dieser Position ist eine Arretierung gegeben.In the embodiment according to claim 1, the outer sleeve and the inner separating area can be designed as a one-piece unit, the contact elements also being sleeve-like and can be inserted into the space between the outer sleeve and the inner separating area and into the interior of the inner area. There is a lock in this position.

The first embodiment of a lamp holder 1 shown in FIG. 1 serves to receive and functionally interconnect a glass base lamp 2 with current-carrying lead part 5 shown in FIGS. 2a and 2b. This glass base lamp 2 has two separate contact wires 3 and 4, one Storage area 22 and a lamp base 25. According to FIG. 2b, the current-carrying lead part 5 has two feed lines 6 and 7 which are isolated from one another.

Nach Fig. 1 besteht die Lampenfassung 1 aus zwei hülsenartig gebildeten Kontaktelementen 8 und 9, eine diese Kontaktelemente umschließende Außenhülse 10 und einen im Inneren der Fassung 1 angeordneten, die Kontaktelemente 8, 9 voneinander isolierenden Innentrennbereich 11. Hierbei sind die Außenhülse 10 und der Innentrennbereich 11 als einstückige Einheit ausgebildet.1, the lamp holder 1 consists of two sleeve-like contact elements 8 and 9, an outer sleeve 10 enclosing these contact elements and an inner separating area 11 arranged inside the socket 1 and isolating the contact elements 8, 9 from one another. Here, the outer sleeve 10 and the inner separating area 11 formed as a one-piece unit.

Die beiden Kontaktelemente 8 und 9 bestehen aus einem elektrisch leitfähigen Kunststoffmaterial und sind jeweils hülsenartig gestaltet.The two contact elements 8 and 9 consist of an electrically conductive plastic material and are each designed like a sleeve.

Wie aus Fig. 1 und 3 ersichtlich, ist die Außenhülse 10 z. B. über drei, über den Umfang verteilt angeordnete Stege 12, 13, 14 mit dem Innentrennbereich 11 verbunden. In dem Zwischenraum 15 zwischen der Außenhülse 10 und dem Innentrennbereich 11 ist hierbei das äußere hülsenartig ausgebildete Kontaktelement 9 eingesetzt. In den Innenraum 16 des Innentrennbereichs 11 wird das innere Kontaktelement 8 eingesetzt. Beide Kontaktelemente 8 und 9 sind verliersicher innerhalb des jeweiligen Raums 15 bzw. 16 angeordnet.1 and 3, the outer sleeve 10 is z. B. connected to the inner separation region 11 via three webs 12, 13, 14 arranged distributed over the circumference. In the intermediate space 15 between the outer sleeve 10 and the inner separating area 11, the outer sleeve-like contact element 9 is inserted. The inner contact element 8 is inserted into the interior 16 of the inner separation region 11. Both contact elements 8 and 9 are arranged captively within the respective space 15 or 16.

Zur funktionssicheren Halterung weisen beide, hülsenartig ausgebildete Kontaktelemente 8 und 9 jeweils mindestens eine Anschlagfläche 19 bzw. 20 auf. Diese Anschlagflächen 19 bzw. 20 können sich an eine entsprechende Schulter 17 bzw. 18 der Außenhülse 10 bzw. des Innentrennbereichs 11 anlegen.For functionally reliable mounting, both contact elements 8 and 9, designed like sleeves, each have at least one stop surface 19 or 20. These stop surfaces 19 and 20 can rest against a corresponding shoulder 17 and 18 of the outer sleeve 10 and the inner separating region 11.

Um die funktionsrichtige Anordnung des äußeren Kontaktelements zwischen der Außenhülse 10 und dem Innentrennbereich 11 zu gewährleisten, weist das äußere Kontaktelement 9 mindestens einen sich in den betreffenden Steg 12, 13 bzw. 14 zwischen Außenhülse 10 und Innentrennbereich 11 einlagerbaren Schlitz 21 nach Fig. 4 auf.In order to ensure the functionally correct arrangement of the outer contact element between the outer sleeve 10 and the inner separating region 11, the outer contact element 9 has at least one in the relevant web 12, 13 or 14 between the outer sleeve 10 and the inner separating region 11 of the slot 21 according to FIG. 4.

Weiterhin ist aus Fig. 4 ersichtlich, daß das äußere Kontaktelement 9 eine halsartige Lagerzone 23 besitzt, welche stirnseitig in einer Konusform 24 ausläuft. Diese halsartigen Lagerzone 23 ist auf den Durchmesser des Lagerbereichs 22 der zu halternden Glassockellampe 2 nach Fig. 2a abgestellt.4 that the outer contact element 9 has a neck-like bearing zone 23, which ends in a conical shape 24 on the end face. This neck-like storage zone 23 is adjusted to the diameter of the storage area 22 of the glass base lamp 2 to be held according to FIG. 2a.

Aus Fig. 5 und 6 ist ersichtlich, daß die Lagerzone 23 entweder Zylinderform 23 oder profilierte Form 23' aufweisen kann. Aus beiden Figuren ist darüber hinaus ersichtlich, daß das äußere Kontaktelement mindestens eine Anschlagfläche 19 aufweist.5 and 6 that the bearing zone 23 can have either cylindrical shape 23 or profiled shape 23 '. It can also be seen from both figures that the outer contact element has at least one stop surface 19.

Fig. 7 stellt das innere Kontaktelement 8 dar. Dieses besitzt zwei durch eine Trennwand 40 voneinander getrennte Sacklöcher 26 und 27. Hierbei ist das Sackloch 27 durch vorzugsweise mindestens einen Schlitz 28 unterteilt. Der Durchmesser des Sackloches 26 ist auf den Durchmesser des Lampensockels 25 der Glassockellampe 2 nach Fig. 2a abgestellt; der Durchmesser des Sackloches 27 des inneren Kontaktelements 8 ist auf den Durchmesser der Zuleitung 6 des Strom führenden Zuleitungsteils 5 abgestellt.7 shows the inner contact element 8. This has two blind holes 26 and 27 separated from one another by a partition 40. Here, the blind hole 27 is preferably divided by at least one slot 28. The diameter of the blind hole 26 is adjusted to the diameter of the lamp base 25 of the glass base lamp 2 according to FIG. 2a; the diameter of the blind hole 27 of the inner contact element 8 is adjusted to the diameter of the lead 6 of the current-carrying lead part 5.

Ist die aus Außenhülse 10, äußerem Kontaktelement 9, innerem Kontaktelement 8 und Innentrennbereich 11 bestehende Lampenfassung 1 gemäß Fig. 1 funktionsrichtig montiert, so läßt sich von oben die Glassockellampe 2 einschieben, wobei sich der Lagerbereich 22 der Glassockellampe 2 in der elastischen Lagerzone 23 des äußeren Kontaktelements 9 einlagert. Nach beendeter Montage beaufschlagt der Kontaktdraht 3 das innere Kontaktelement 8; der andere Kontaktdraht 4 beaufschlagt das äußere Kontaktelement 9.If the lamp holder 1 according to FIG. 1, which is composed of the outer sleeve 10, the outer contact element 9, the inner contact element 8 and the inner separating region 11, is mounted in the correct manner, the glass base lamp 2 can be inserted from above, the bearing region 22 of the glass base lamp 2 being in the elastic bearing zone 23 of the outer contact element 9 stores. After assembly is complete, the contact wire 3 acts on the inner contact element 8; the other contact wire 4 acts on the outer contact element 9.

Das Strom führende Zuleitungsteil 5 läßt sich von unten in die erfindungsgemäße Lampenfassung einführen, wobei sich die Zuleitung 6 im unteren Sackloch 27 des inneren Kontaktelements 8 einlagert. Die andere Zuleitung 7 beaufschlagt mit ihrer Außenfläche die Innenwandung des äußeren Kontaktelements 9. Damit ist in funktionsrichtiger Weise eine Verbindung zwischen den Kontaktdrähten 3 und 4 der Glassockellampe 2 mit den Zuleitungen 6 und 7 des Strom führenden Zuleitungsteils 5 hergestellt.The current-carrying lead part 5 can be inserted from below into the lamp holder according to the invention, the lead 6 being embedded in the lower blind hole 27 of the inner contact element 8. The other lead 7 acts on the inner wall of the outer contact element 9 with its outer surface. A connection between the contact wires 3 and 4 of the glass base lamp 2 and the leads 6 and 7 of the current-carrying lead part 5 is thus established in a functionally correct manner.

Da die beiden Kontaktelemente 8 und 9 aus elektrisch leitfähigem Kunststoffmaterial bestehen, ergibt sich eine erhebliche Vereinfachung der gesamten Bauform bei kostensparender Montage.Since the two contact elements 8 and 9 consist of electrically conductive plastic material, the overall design is considerably simplified with cost-saving assembly.

Wie ersichtlich, liegen die Anschlagflächen 19 bzw. 20 des inneren bzw. äußeren Kontaktelements 8, 9 an den entsprechenden Schultern 17 bzw. 18 der Außenhülse 10 bzw. des inneren Trennbereichs 11 an. Damit ist eine exakte Justierung der einzelnen Elemente innerhalb der Außenhülse 10 der erfindungsgemäßen Lampenfassung 1 gegeben.As can be seen, the abutment surfaces 19 and 20 of the inner and outer contact elements 8, 9 abut the corresponding shoulders 17 and 18 of the outer sleeve 10 and the inner separating area 11, respectively. This provides an exact adjustment of the individual elements within the outer sleeve 10 of the lamp holder 1 according to the invention.

Alternativ besteht auch die Möglichkeit, die gesamte Einheit im Zwei-Komponenten-Spritzverfahren herzustellen.Alternatively, it is also possible to manufacture the entire unit using the two-component injection molding process.
