Description

Einrichtung zur Verwendung von Mehrfadenglühlampen mit Schraubsockel und federndem Stirnkontakte in normaldn Schraubfassungen, Die Erfindung betrifft eine Einrichtung, welche es ermöglicht, die bekannten Glühlampen mit- mehreren voneinander unabhängigen Glühfäden in normalen Schraubfassungen zu verwenden. Während die bekannten Mehrfadenglühlampen meist eine besonders ausgebildete Fassung erforderlich machen oder aber mehr oder weniger kompliziert gestaltete Lampensockel aufweisen, kann der Erfindung gemäß jede normale Fassung durch Einschrauben einer in den Gewindekorb der Fassung passenden, aus Isoliermaterial bestehenden und mit Metallaußengewinde versehenen Hülse zur Aufnahme einer verhältnismäßig einfach konstruierten Mehrfadenglühlampe an sich bekannter Bauart benutzbar gemacht werden. Diese Einschraubhülse hat ein Innengewinde zur Aufnahme des Lampensockels, in das ein über einige Gewindegänge reichender, mit dem Metallaußengewinde in stromleitender Verbindung stehender Ring eingelegt ist, der zur Überleitung des Stromes an die durch Hin- und Herschrauben der Lampen wahlweise mit ihm in oder außer Berührung zu bringenden Kontaktplättchen der Glühfadenenden dient.Device for using multi-filament incandescent lamps with a screw base and resilient end contacts in normal screw sockets, The invention relates a device which makes it possible to use the known incandescent lamps with several of each other to use independent filaments in normal screw sockets. While the known Multi-filament incandescent lamps usually require a specially designed socket or have lamp bases of more or less complicated design according to the invention any normal socket by screwing one into the threaded basket matching the socket, made of insulating material and with an external metal thread provided sleeve for receiving a relatively simply constructed multi-filament incandescent lamp known construction can be made usable. This screw-in sleeve has a Internal thread to accommodate the lamp base, into which one has a few threads Reaching ring that is in electrical connection with the metal external thread is inserted, which is used to transfer the current to the by screwing back and forth of the lamps either with it in or out of contact to be brought into contact with contact plates serves for the filament ends.

Der Gegenstand der Erfindung ist auf der Zeichnung veranschaulicht.The object of the invention is illustrated in the drawing.

Abb. r zeigt einen Schnitt durch die einzuschraubende Hülse, Abb. 2 die Mehrfadenglühlampe.Fig.r shows a section through the sleeve to be screwed in, Fig. 2 the multi-filament light bulb.

Die in den Gewindekorb jeder normalen Fassung einzuschraubende Isolierhülse a besitzt ein stromleitendes Außengewinde b und ein zur Aufnahme des gegenüber einem normalen Lampensockel um die Dicke der Hülse verjüngten Sockels dienendes Innengewinde c. Etwa im mittleren Teile dieses Gewindes befindet sich ein über einige Gewindegänge reichender eingelegter Metallring d, der mit dem Außengewinde in stromleitender Verbindung steht.The insulating sleeve to be screwed into the threaded basket of every normal socket a owns a conductive external thread b and one for receiving of the base, which is tapered by the thickness of the sleeve compared to a normal lamp base serving internal thread c. Approximately in the middle part of this thread is located an inlaid metal ring d which extends over a few threads and which is connected to the external thread is in electrical connection.

Die in ihrem gesamten Aufbau - abgesehen von dem Durchmesser des Lampensockels - mit bekannten derartigen Lampen übereinstimmende Mehrfadenglühlampe besitzt einen unter der Wirkung einer Feder i stehenden Stirnkontakt g, von dem, und zwar von einem angeschlossenen mittleren Leiter 1a, die verschiedenen Glühfäden f ausgehen und gesondert an Kontaktplättchen enden, die außen am Gewinde des aus Isoliermaterial bestehenden Lampensockels in verschiedener Höhe sitzen.The whole structure - apart from the diameter of the lamp base - Multi-filament incandescent lamp matching known such lamps has a front contact g under the action of a spring i, of which, namely of a connected central conductor 1a, the various filaments f run out and ends separately on contact plates, the outside of the thread of the insulating material existing lamp base sit at different heights.

Zwecks Benutzung der eben beschriebenen Lampe in einer normalen Fassung wird die Hülse a in den Gewindekorb der Fassung eingeschraubt und in sie die Lampe, deren Kontaktplättchen e zwecks Ein- oder Ausschaltung der einzelnen Fäden durch mehr oder weniger tiefes Eindrehen wahlweise mit dem Kontaktring d der Fassung in stromleitende Verbindung gebracht werden können. Der Stirnkontakt g wird dabei in bekannter Weise mehr oder weniger in den Lampensockel hineingedrängt.For the purpose of using the lamp just described in a normal socket the sleeve a is screwed into the threaded basket of the socket and the lamp into it, their contact plate e for the purpose of switching the individual threads on or off more or less deep screwing optionally with the contact ring d of the socket in conductive connection can be brought. The forehead contact g is in as is known, more or less pushed into the lamp base.
