Description

Die Erfindung betrifft eine Halterung für eine Lampe, insbes. für eine Halogenlampe mit Sockel GU10 und GU10Z, umfassend eine Lampenfassung und einen Fassungshalter aus Isoliermaterial, wobei der Fassungshalter als von der rückwärtigen Seite der Lampenfassung her auf diese aufzurastende Haube ausgebildet ist und innenseitig der Haube sowie außenseitig der Fassung Rastmittel, von denen die der Haube federelastisch ausweichbar angeordnet und/oder ausgebildet sind, und formschlüssig wirkende Verdrehsicherungsmittel vorhanden sind.The invention relates to a holder for a lamp, esp. For a Halogen lamp with base GU10 and GU10Z, comprising a lamp socket and a socket holder made of insulating material, wherein the socket holder as of the rear side of the lamp holder forth on this aufzurastende hood is formed and the inside of the hood and the outside of the socket Locking means, of which arranged the hood elastically evasive and / or are formed, and positively acting anti-rotation means available.

Zur Halterung einer Lampe genügt grundsätzlich eine Lampenfassung. Für zahlreiche Anwendungsfälle sind jedoch besondere Fassungshalter in Haubenform - auch "Dome" genannt - gebräuchlich, die in der Leuchte montiert werden und mit Rastverbindungsmitteln die Lampenfassung aufnehmen.To hold a lamp basically a lamp socket is sufficient. For many applications, however, special holders are in Hood shape - also called "dome" - in use, which is mounted in the lamp and take up the lampholder with snap fasteners.

Bei den in Bezug genommenen Lampen mit Sockeln GU10 oder GU10Z, für die die erfindungsgemäße Lampenhalterung vornehmlich, wenngleich nicht ausschließlich, bestimmt ist, handelt es sich um Fassungen für Hochvolt-Halogenlampen und die Fassungen bestehen aus keramischem Material wie z.B. Steatit oder einem hochtemperaturbeständigen Kunststoff wie etwa PPS (Polyphenylsulfit) oder LCP (Liquid Crystal Polymer).For the referenced lamps with sockets GU10 or GU10Z, for the lamp holder according to the invention primarily, although not only, is determined, are sockets for high-voltage halogen lamps and the sockets are made of ceramic material like e.g. Steatite or a high temperature resistant plastic such as PPS (Polyphenyl sulfite) or LCP (liquid crystal polymer).

Eine solche Fassung ist beispielsweise Gegenstand der DE 197 14 874 C1 der Anmelderin. Es handelt sich um eine Lampenfassung, in deren Kontakte die parallel zueinander ausgerichteten Lampenkontaktstifte im wesentlichen bajonettartig verriegelt werden. Die Fassung besteht aus einem Fassungskörper und einem diesen verschließenden Boden, die miteinander über zwei fluchtende Bohrungen vernietet sind. Such a version is for example the subject of DE 197 14 874 C1 of the Applicant. It is a lamp holder, in the contacts of which aligned parallel lamp contact pins in be locked essentially bayonet-like. The version consists of a Socket body and a closing this floor, with each other are riveted over two aligned holes.

Für Fassungen dieser Art gibt es haubenförmige Fassungshalter aus thermoplastischem Material wie beispielsweise PBT (Polybutylenterephtalat). Die Mäntel der Fassungshalter sind mit zwei einander gegenüberliegenden, sich axial erstreckenden Rippen versehen, die in die entsprechend angepassten Nuten am Mantel des Fassungskörpers (vgl. etwa die Nuten in Fig. 2 von DE 197 14 874 C1 bei ca. 11 und 16 Uhr) passen und für eine Verdrehsicherung zwischen Fassung und Haube sorgen können. Die Verdrehsicherung ist insoweit wichtig, als beim Einsetzen der Lampe in die Fassung diese sich zu verdrehen neigt. Da dies gegen die in der Leuchte festgesetzte Haube erfolgt, könnte es geschehen, dass sich die Teile ohne Verdrehsicherung gegeneinander verdrehen. Dadurch werden die Anschlussdrähte unzulässig bewegt und könnten sogar abreißen.For versions of this kind there are hood-shaped frame holder thermoplastic material such as PBT (polybutylene terephthalate). The coats of the frame holders are two opposing, provided axially extending ribs in the corresponding matched grooves on the shell of the socket body (see, for example, the grooves in Fig. 2 of DE 197 14 874 C1 at about 11 and 16 clock) fit and for a Anti-rotation between socket and hood can provide. The Anti-rotation is important in so far as when inserting the lamp in the This version tends to twist. Because this is against the in the light fixed hood done, it could happen that the parts without Turn anti-rotation lock against each other. This will be the Connecting wires moved inadmissible and could even tear.

Diese genannte Art der Verdrehsicherung ist in der Praxis allerdings nicht sehr zuverlässig. Dazu ist zu beachten, dass Haube und Fassung durch axiales Ineinanderstecken miteinander verrastet werden. Da die Fassung aus einem starren Material besteht, muss die zum Verrasten vorübergehend benötigte Elastizität aus dem Haubenmaterial gewonnen werden.This type of anti-rotation is in practice, however not very reliable. It should be noted that hood and socket by axial nesting are locked together. Since the version off A rigid material must be temporarily locked into place required elasticity can be obtained from the hood material.

Da die genannten Verdrehsicherungsmittel nur von geringer Höhe sind und daher einen nur geringen gegenseitigen Eingriff haben, andererseits die Haube elastisch gehalten ist, kann ein gegenseitiges Verdrehen bei Einwirkung höherer Kräfte nicht verhindert werden. Höhere Kräfte treten bei Fassungen insbesondere der bevorzugten Anwendung der Erfindung deshalb ein, weil die Einsteckbewegung der Lampe nach Art einer Bajonettverriegelung erfolgt, also über einen kurzen Drehweg mit plötzlichem Erreichen der Endstellung, die der eilige Benutzer vielleicht zu spät wahrnimmt, um die Eindrehbewegung noch früh genug zu stoppen.Since the said anti-rotation means are only of small height and therefore have little mutual interference, on the other hand the Hood is held elastic, can be a mutual twisting under impact higher forces can not be prevented. Higher forces occur in versions in particular, the preferred application of the invention therefore, because the Plug-in movement of the lamp in the manner of a bayonet lock done, so over a short turning distance with sudden reaching of the end position, which the urgent user may perceive too late to the screwing motion yet to stop early enough.

Man könnte die Wirksamkeit der Verdrehsicherungsmittel zwischen Haube und Fassung erhöhen, wenn man die haubeninnenseitigen Rippen höher machen oder scharfkantig ausbilden würde. Dies allerdings würde bedingen, dass man auch die Mantelnuten in der Fassung entsprechend anpasst. Dies wiederum würde eine Neukonstruktion auch der Fassung erfordern, die insoweit standardmäßig von vielen Herstellern hergestellt wird. Außerdem besteht die Schwierigkeit, dass der keramische Körper an sich schon durch die Mantelnuten geringer Tiefe geschwächt wird und nicht noch weiter geschwächt werden darf.You could see the effectiveness of the anti-rotation device between Increase hood and socket, if the hood inside ribs make it higher or sharp-edged. This, however, would condition that you also the sheath grooves in the version accordingly adapts. This in turn would require a redesign of the socket, which is standard manufactured by many manufacturers. There is also the difficulty that the ceramic body in itself is already weakened by the sheath grooves shallow depth and not yet may be further weakened.

Die aufgezeigten Probleme haben viele Fassungshersteller dazu veranlasst, Hauben anzubieten, in die die Fassung durch zwei axiale Schrauben befestigt wird, was jedoch einen Mehraufwand bedeutet.The indicated problems have many socket manufacturers caused to offer hoods in which the socket by two axial Screw is attached, which means an extra effort.

Folglich liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Lampenhalterung der im Oberbegriff des Anspruches 1 näher umrissenen Art anzugeben, die einen besonders sicheren Verdrehschutz zwischen der Lampenfassung und dem haubenartigen Fassungshalter aufweist.Consequently, the present invention has the object, a Lamp holder in the preamble of claim 1 further outlined type specify a particularly secure twist protection between the Lamp holder and the hood-like socket holder has.

Die Erfindung löst diese Aufgabe mit den Merkmalen des Anspruches 1 und ist dementsprechend dadurch gekennzeichnet, dass die haubenseitigen Verdrehsicherungsmittel mindestens einen von der Elastizität der Haube entkoppelten Zapfen umfassen, der in eine Zapfenaufnahme der Fassung eingreift, wenn Haube und Fassung miteinander verbunden werden.The invention solves this problem with the features of claim 1 and is accordingly characterized in that the hood side Anti-rotation means at least one of the elasticity of the hood comprise decoupled pins, which engages in a pin receptacle of the socket, when hood and socket are connected together.

Der wesentliche Kern der Erfindung besteht also darin, dass man die Verdrehsicherungsmittel nicht an den elastisch aufspreizbaren Partien des Lampenhalters anordnet. Aufgrund dieser Entkopplung der Verdrehsicherungsmittel von der Spreizelastizität der Haube wird erreicht, dass Kräfte im Sinne einer Verdrehbewegung einer Fassung gegenüber der Haube sicher abgefangen werden und nicht zu einem Aufspreizen der Haube führen können.The essential core of the invention is therefore that one the Anti-rotation means not on the elastically expandable parts of the Arranges lamp holder. Because of this decoupling of Anti-rotation means of the expansion elasticity of the hood is achieved that Forces in the sense of a twisting movement of a socket against the hood be safely intercepted and do not lead to a spreading of the hood can.

Die hieraus resulierenden Vorteile der Erfindung sind erheblich. Zum einen ist es nicht notwendig, an der Fassung selbst Änderungen vorzunehmen. Auch die dort bereits vorhandenen Mantelnuten könnten als wirksame Bestandteile der Verdrehsicherungsmittel herangezogen werden, sofern der Zapfen haubenseitig nur starr genug ausgeführt ist.The resulting advantages of the invention are significant. To the it is not necessary to make any changes to the version itself. Even the existing sheath grooves could be effective Components of the anti-rotation means are used, provided that Journal hood side is designed only rigid enough.

Ein weiterer Vorteil der Erfindung besteht darin, dass die Haube problemlos mit Mantelaussparungen versehen werden kann, die einerseits den Vorteil haben, die Elastizität, die für das Aufrasten von Haube und Fassung erforderlich ist, zu erhöhen. Andererseits können die Mantelausnehmungen nunmehr so großzügig ausgebildet werden, dass sie als Leiterdurchführungen dienen können. Bei dem bisher in Bezug genommenen Stand der Technik ist dies grundsätzlich unmöglich.Another advantage of the invention is that the hood can be easily provided with Mantelaussparungen, on the one hand the Have the advantage of elasticity, for snapping hood and socket is required to increase. On the other hand, the Mantelausnehmungen now be made so generous that they as conductor bushings can serve. In the previously referred to prior art this is basically impossible.

Eine bevorzugte Weiterbildung der Erfindung sieht vor, dass haubeninnenseitig zwei Zapfen diametral einander gegenüberliegend vorgesehen sind, die innenseitig am Haubenboden angeformt sind und sich parallel zur Längsmittelachse (Rotationsachse) der Haube erstrecken und dass als Zapfenaufnahme der Fassung die dort vorhandenen Hohlnieten dienen, die den Fassungskörper mit einer Verschlussplatte zusammenhalten und durch die hindurch eine Anschraubmontage möglich ist. Mit Hilfe dieser Merkmale macht sich die Erfindung die bislang völlig unentdeckte Tatsache zunutze, dass die standardmäßig vorhandenen Fassungen die bislang nicht ausgeschöpften Mittel bereits aufweisen, die man zur Steckverbindung mit den Zapfen heranziehen kann. Hierin wird ein besonderer Erfolg der vorliegenden Erfindung gesehen. Man erzielt eine Drehfestigkeit der Lampenhalterung, die bisher nur durch Einsatz von Schrauben möglich war.A preferred development of the invention provides that Hood inside two pins diametrically opposite each other are provided, which are integrally formed on the hood bottom and itself extend parallel to the longitudinal central axis (axis of rotation) of the hood and that serve as a pin receiving the socket the existing there rivets, the hold the socket body together with a closure plate and through the Through a screw mounting is possible. With the help of these features makes the invention exploits the hitherto completely undiscovered fact that the standard versions that are not yet exhausted Means already have, which one to the plug connection with the pin can draw on. This is a particular achievement of the present invention seen. It achieves a torsional strength of the lamp holder, the only so far by using screws was possible.

Die in ihrer Gesamtheit mit 10 bezeichnete Lampenhalterung umfaßt eine Lampenfassung 11 und einen Fassungshalter 12.The lamp holder designated in its entirety by 10 comprises a lamp holder 11 and a holder holder 12th

Die Fassung 11 besteht aus hochtemperaturbeständigem Material wie beispielsweise Keramik oder einem geeigneten Kunststoffmaterial. Beim dargestellten Ausführungsbeispiel handelt es sich um eine Fassung zur Aufnahme von Lampen mit Sockeln GU10 oder GZ10, also für Halogen-Hochvoltlampen. Solche Lampen weisen zwei parallel zueinander ausgerichtete Kontaktstifte auf, die durch einen bajonettartigen Kupplungsvorgang mit den in der Fassung 11 enthaltenen, in den Zeichnungen nicht dargestellten Kontakten zusammengebracht werden. Bezüglich des Aufbaus einer solchen Fassung sei beispielhaft auf DE 197 14 874 C1 Bezug genommen.The version 11 is made of high temperature resistant material such For example, ceramic or a suitable plastic material. At the illustrated embodiment is a socket for recording of lamps with sockets GU10 or GZ10, ie for halogen high-voltage lamps. Such lamps have two parallel aligned Contact pins, which by a bayonet coupling process with the in the version 11 contained, not shown in the drawings contacts be brought together. Regarding the structure of such a version is by way of example to DE 197 14 874 C1.

Der Fassungshalter 12 besteht aus einem elastischen, thermoplastischen Material wie z.B. PBT. Er ist dazu bestimmt, an einem Leuchtenblech oder in einem Reflektorgehäuse einer Leuchte fest verankert zu werden und die Lampenfassung 11 zu tragen. Der üblicherweise auch mit "Haube", "Isolierhaube" oder "Kunststoffkappe" bezeichnete Fassungshalter 12 ist mit der Fassung 11 im Zuge einer Steckverbindung in Richtung der gemeinsamen Längsmittelachse L verrastbar. Hierzu weist der Fassungshalter 12 an der Innenseite seines Haubenmantels 12a vier umfangsversetzte Rastnasen 13 auf, denen Rastausnehmungen 14 am Mantel der Fassung 11 gegenüberstehen. Die Rastungen 13, 14 haben die Aufgabe, die Teile 11 und 12 in Richtung der Längsachse L fest aneinander zu halten.The frame holder 12 consists of an elastic, thermoplastic material such as e.g. PBT. He is destined to be one Fitted sheet or firmly anchored in a reflector housing a lamp be and carry the lamp holder 11. The usually also with "Hood", "insulating hood" or "plastic cap" designated socket holder 12 is with the version 11 in the course of a plug connection in the direction of common longitudinal center axis L latched. For this purpose, the socket holder 12 on the inside of its hood sheath 12a four circumferentially offset Latches 13, which recesses 14 on the casing of the socket 11th face. The detents 13, 14 have the task of the parts 11 and 12 in the direction of the longitudinal axis L to hold firmly together.

Davon unabhängig und umfangsversetzt sind Innenmantelrippen 15 am Fassungshalter 12 und Mantelnuten 16 am Fassungskörper 11 vorgesehen. Diese dienen beim Stand der Technik als Verdrehsicherungsmittel, wohingegen sie hier im wesentlichen zur Umfangsorientierung und zur Axialführung dienen.Independently and circumferentially offset are inner jacket ribs 15 am Frame holder 12 and shell grooves 16 provided on the socket body 11. These serve in the prior art as anti-rotation, whereas They serve here essentially for circumferential orientation and axial guidance.

Verdrehsicherungsmittel wie 15, 16 können wegen ihrer geringen Radialerstreckung und damit ihrer geringen Überdeckung nicht sicher verhindern, dass beim Einsetzen einer Lampe in die Einstecköffnungen 17 der Lampenfassung 11 die Fassung 11 gegenüber dem an der Leuchte festgehaltenen Fassungsträger 12 doch verdreht wird, und zwar infolge elastischen Aufweitens des Mantels des haubenförmigen Fassungshalters 12.Anti-rotation means such as 15, 16 may be due to their low Radial extension and thus their low coverage not sure prevent the insertion of a lamp in the insertion 17 of the Lampholder 11 the socket 11 opposite to the light festgehaltenen socket holder 12 is twisted, due to elastic Expands the jacket of the hood-shaped socket holder 12th

Deshalb ist erfindungsgemäß zur Verdrehsicherung der Halterungsteile 11 und 12 gegeneinander folgendes vorgesehen:Therefore, according to the invention for preventing rotation of the support parts 11 and 12 provided against each other:

Es sind am starren Boden 12b des haubenförmigen Fassungshalters 12 innenseitig zwei sich parallel zur Längsmittelachse L erstreckende Zapfen 18 vorhanden, die von Wandungsteilen des Fassungshalters 12, also von der Elastizität der Haube 12 völlig entkoppelt sind. Die Zapfen 18 finden ihr Verdreh-Widerlager in axial gerichteten Durchbrüchen 19 der Fassung 11. Bei diesen Durchbrüchen 19 handelt es sich um die Hohlnieten, mit denen der Hauptkörper der Fassung 11 mit einem Verschlussdeckel 11a vernietet ist. Den formschlüssigen Eingriff der Zapfen 18 in die entsprechenden Löcher zeigt Fig. 6, wobei allerdings dort die Hohlnieten nicht gezeigt sind.There are on the rigid bottom 12 b of the hood-shaped socket holder 12th on the inside two parallel to the longitudinal central axis L extending pin 18th present, by Wandungsteilen the socket holder 12, so from the Elasticity of the hood 12 are completely decoupled. The pins 18 find their torsion abutment in axially directed openings 19 of the version 11. Bei These openings 19 are the hollow rivets with which the Main body of the socket 11 is riveted to a closure lid 11a. The positive engagement of the pin 18 in the corresponding holes shows Fig. 6, although there the hollow rivets are not shown.

Wie aus der Beschreibung und den Zeichnungen ersichtlich wurde, ist die durch diesen formschlüssigen Teileeingriff bewirkte Verdrehsicherung völlig unabhängig von der elastischen Auswärtsverformung von Wandungsteilen der Haube 12. Aus diesem Grund kann die Haube 12 die in den Figuren erkennbaren sehr großzügigen Mantelausnehmungen 20 aufweisen, die einerseits eine hohe Elastizität der von ihnen geschaffenen aufweitbaren Wandungsteile bewirken und es andererseits gestatten, Leiter zu den Leiter Anschlussstellen der Fassung 11 durch sie hindurch zu führen.As has become apparent from the description and the drawings, is the distortion caused by this positive part engagement completely regardless of the elastic outward deformation of wall parts of the Hood 12. For this reason, the hood 12 can be seen in the figures recognizable very generous Mantelausnehmungen 20, the on the one hand a high elasticity of the created by them expandable Wall parts cause and on the other hand allow, ladder to the ladder Connection points of the version 11 to pass through them.
