Description
Die Erfindung betrifft eine Lampenfassung, insbes. Fassung für Halogen-Hochvoltlampen, umfassend einen zur Aufnahme des Lampensockels bestimmten Fassungsstein aus temperaturfestem Material wie Keramik, Porzellan od. dgl. und eine den Fassungsstein leiteranschlussseitig im wesentlichen bis auf Leitereinführöffnungen verschließendende Abdeckung, sowie elektrische Kontakte mit je wenigstens einer schraubenlosen Anschlussklemme für einen einzusteckenden Leiter, wobei die Kontakte von Fassungsstein und Abdeckung in deren zusammengefügtem Zustand unverlierbar in der Fassung gehalten sindThe invention relates to a lamp socket, in particular. Version for Halogen high-voltage lamps, including one for receiving the lamp cap certain socket made of temperature-resistant material like ceramics, porcelain or the like, and a socket stone conductor connection side essentially closing up on conductor insertion openings Cover, as well as electrical contacts with each at least one screwless terminal for a einzusteckenden Ladder, with the contacts of socket stone and cover in their assembled state captive in the socket are held
Die Erfindung geht aus von einer druckschriftlich nicht belegbaren, offenkundig vorbenutzten Lampenfassung für Halogen-Hochvoltlampen mit Sockel G9. Diese bekannte Fassung weist einen Fassungsstein aus Keramik auf mit Aufnahmekammern für zwei Kontakte und mit zwei Durchstecköffnungen für die Schenkel einer U-förmigen Haltefeder, die kraftschlüssig am Sockel der Lampe angreifen und diese am Herausfallen aus der Fassung hindern. Die Kontakte liegen vollständig in den Höhlungen der Aufnahmekammern und sind selbsttragend nach Art von Käfigkontakten ausgebildet. Diese Kontaktgestaltung erfordert einen beträchtlichen Aufwand an Kontaktmaterial und zahlreiche Bearbeitungsstufen, um den Kontakt durch Stanzen und Biegen aus einem Blech zu formen. Ferner weist diese bekannte Fassung als Abdeckung einen im wesentlichen flachen, die leiteranschlussseitige Öffnung des Fassungssteins verschießenden Deckel aus formbeständigem Werkstoff wie LCP (Liquid Crystal Polymer) auf. Dieser Deckel ist am Fassungsstein mittels Hohlnieten befestigt.The invention is based on a documentary non-assignable, obviously pre-used lamp socket for halogen high-voltage lamps with base G9. This known version has a socket stone ceramic on with receiving chambers for two contacts and with two through openings for the legs of a U-shaped Retaining spring, the non-positively attack on the base of the lamp and prevent them from falling out of the socket. The contacts are completely in the cavities of the receiving chambers and are self-supporting formed in the manner of cage contacts. This contact design requires a considerable amount of contact material and Numerous processing steps to contact through punching and Bending from a sheet to form. Furthermore, this known version as cover a substantially flat, the conductor connection side Opening of the lampholder shutting lid made of dimensionally stable material such as LCP (Liquid Crystal Polymer). This cover is attached to the socket stone by means of hollow rivets.
Aus EP 0 778 639 A1 ist ebenfalls eine Lampenfassung bekannt, deren Fassungsstein Aufnahmekammern enthält, in denen jeweils ein Kontakt allerdings anderer Konfiguration vollständig untergebracht ist. Folglich befasst sich EP 0 778 639 A1 mit dem speziellen Problem, die Kontakte selbst so zu gestalten, dass sie besonders sicher in ihrer Aufnahmekammer gehalten und arretiert sind.From EP 0 778 639 A1 is also a lamp socket known, whose socket stone contains receiving chambers in which one contact, however, completely accommodated other configuration is. Consequently, EP 0 778 639 A1 deals with the specific Problem to make the contacts themselves so that they are special securely held in their receiving chamber and locked.
Bei dem erörterten, insbesondere dem an erster Stelle genannten Stand der Technik ist es aus thermischen Gründen günstig, dass die Kontakte in dem temperaturfesten Teil der Fassung, nämlich dem Fassungsstein, eingebettet sind. Daraus resultiert, da die die Kontakte umgebenden Fassungspartien sich nicht verformen können, eine sichere Kontaktgabe und ein zuverlässiger Leiteranschluss. Andererseits sind aber werkstoffbedingt Bauteile aus Keramik oder Porzellan mit erheblichen Toleranzen behaftet, was ein Grund für die aufwendige Kontaktgestaltung nach dem selbsttragenden Käfigprinzip sein mag.In the discussed, in particular the first mentioned State of the art, it is favorable for thermal reasons that the contacts in the temperature-resistant part of the socket, namely the Masonry stone, are embedded. This results because the the contacts surrounding socket sections can not deform, a secure contact and a reliable conductor connection. On the other hand, however, material-related components made of ceramic or Porcelain is subject to considerable tolerances, which is one reason for the complex contact design according to the self-supporting cage principle may be.
Abgesehen von den erforderlichen Hohlnieten zur Verbindung von Fassungsstein und Deckel ist die bekannte Fassung auch für eine automatisierte Fertigung geeignet, da die Kontakte und die Haltefeder lediglich lose in den Fassungsstein eingelegt müssen und dann nur noch der Deckel aufgesetzt zu werden braucht.Apart from the required hollow rivets for connection of Fassungsstein and cover is the well-known version also for a automated manufacturing suitable because the contacts and the retaining spring only loosely inserted in the socket stone and then only still the lid needs to be put on.
Der Erfindung liegt im wesentlichen die Aufgabe zugrunde, eine Fassung der im Oberbegriff des Anspruches 1 als bekannt vorausgesetzten Art zu schaffen, die sich insbesondere durch geschickte und Werkstoff sparende Auslegung der Kontakte und durch hohe Maßhaltigkeit wie auch zuverlässige Kontaktgabe auszeichnet. Zumindest eine Weiterbildung des Erfindungsgedankens soll auch eine einfache Montagemöglichkeit gewährleisten.The invention is essentially based on the object, a Version presupposed in the preamble of claim 1 as known To create kind, in particular through skillful and Material-saving design of the contacts and high dimensional stability as well as reliable contact characterizes. At least a development of the inventive concept should also be a simple Ensure mounting option.
Die Erfindung ist in erster Linie dadurch gekennzeichnet, dass jeder Kontakt einen Basissteg aufweist, an dem wenigstens eine schraubenlose Anschlussklemme ausgebildet ist mit einem Klemmfederabschnitt und einem Widerlagerabschnitt für das anzuschließende Leiterende und dadurch, dass im Fassungsstein jeweils eine Sacköffnung vorgesehen ist, in die der Widerlagerabschnitt und das Leiterende eintauchen und sich darin seitlich abstützen können.The invention is primarily characterized in that each contact has a base bar on which at least one screwless terminal is formed with a clamping spring portion and an abutment portion for the to be connected Ladder end and in that in the holding stone one each Sack opening is provided, in which the abutment portion and the Dip the end of the ladder and be able to support itself laterally.
Ein wesentliches Prinzip der Erfindung besteht also in der ,schlichten' Ausgestaltung des Kontakts, der, abgesehen von einem notwendigen Kontaktabschnitt für die Lampenkontakt, im wesentlichen lediglich einen Basissteg und wenigstens eine daran anschließende schraubenlose Anschlussklemme aufzuweisen braucht, Diese wiederum benötigt lediglich einen Klemmfederabschnitt und einen Widerlagerabschnitt, um ein Leiterende zuverlässig kontaktieren zu können.An essential principle of the invention is thus in the to 'design' the contact, which, apart from one necessary contact portion for the lamp contact, essentially only a base bar and at least one adjoining screwless terminal needs to have, this in turn only needs a clamping spring section and an abutment section, to reliably contact a conductor end.
Des weiteren ist es erfindungsgemäß wesentlich, dass im Fassungsstein lediglich Sacköffnungen zur Aufnahme des Leiterendes und des Widerlagerabschnitts des Kontakts (sowie ggf. des Klemmfederabschnitts oder eines Teils desselben) vorgesehen sind, jedoch keine großvolumigen Kammern zur vollständigen Kontaktaufnahme. Hieraus resultieren mehrere Vorteile. Zum einen ist die thermisch empfindlichen Anschlussklemme zu einem hinreichenden Teil, nämlich dem Widerlagerabschnitt sicher und abgestützt im Keramikteil untergebracht. Zum anderen liegen Kontaktabschnitte vor, und zwar im wesentlichen zumindest der Basisabschnitt des Kontakts, die sich sicher positioniert oder vorpositioniert in der Abdeckung unterbringen lassen, was die Montage sehr erleichtert. Im übrigen begrenzen die Sacköffnungen in vorteilhafter Weise automatisch die Einstecktiefe der Leiterenden - ein weiteres Kriterium im Hinblick auf eine reproduzierbar zuverlässige Kontaktgabe.Furthermore, it is essential according to the invention that in the Masonry Stone only blind openings for receiving the conductor end and the abutment portion of the contact (and possibly the clamping spring portion or part of it), however no large-volume chambers for full contact. This results in several advantages. For one, the thermal sensitive terminal to a sufficient part, namely the abutment portion safely and supported housed in the ceramic part. On the other hand there are contact sections, in the essential at least the base section of the contact, which is safely positioned or prepositioned in the cover which makes assembly a lot easier. Otherwise limit the Sack openings advantageously automatically the insertion depth of Ladder ends - another criterion with regard to a reproducible reliable contact.
Die schraubenlose Anschlussklemme kann an einer Schmalseite des Basisstegs des Kontakts ausgebildet sein. Eine besonders Material sparende Kontaktausbildung ergibt sich, wenn entsprechend weiterer Ausgestaltung, sich der Basissteg im wesentlichen über die gesamte Länge des Kontakts erstreckt und im Anschluss an wenigstens eine endseitige Umbiegungen der Widerlagerschenkel ausgebildet ist, während der Klemmfederschenkel aus einem Teil der Länge und einem Teil der Breite des Basisabschnitts ausgeschnitten und abgebogen ist. Damit kann ein Teilabschnitt des Basisstegs und ein Klemmfederschenkel abfallfrei aus einem Blechabschnitt gewonnen werden. The screwless terminal can be on a narrow side be formed of the base bridge of the contact. A special Material-saving contact training results if appropriate further embodiment, the base web substantially over the entire length of the contact extends and following at least formed an end bends of the abutment legs is, while the clamping spring leg of a portion of the length and a portion of the width of the base portion cut out and is bent. This can be a section of the base bar and a Clamping leg obtained without waste from a sheet metal section become.
Ein weiteres Merkmal der Erfindung sieht vor, dass der Fassungsstein mit zu jeder Sacköffnung führenden Schrägflächen versehen ist, die die Klemmfederabschnitte der Kontaktfeder flankieren und einen Überdehnanschlag für sie ausbilden. Ferner liegt der in die Sacköffnung eingreifende Widerlagerabschnitt des Kontakts vorzugsweise unter federnder Vorspannung an der Wand der Sacköffnung an und ist dem entsprechend besonders sicher und temperaturresistent im Fassungsstein untergebracht.Another feature of the invention provides that the socket stone provided with leading to each bag opening inclined surfaces is that flank the clamping spring portions of the contact spring and train an overstretch stop for them. Furthermore, the lies in the Sack opening engaging abutment portion of the contact preferably under spring bias on the wall of the bag opening and is therefore particularly safe and temperature resistant housed in the mount stone.
Kontakte einer gattungsgemäßen Lampenfassung benötigen auch einen Kontaktabschnitt für den zugehörigen Lampenkontakt. Dieser Kontaktabschnitt kann ebenfalls Werkstoff sparend angeordnet sein, und zwar nach einem Merkmal der Erfindung als Kontaktzunge an der Breitseite des Basisstegs des Kontakts.Need contacts a generic lamp holder also a contact section for the associated lamp contact. This Contact section can also be arranged to save material be, according to a feature of the invention as a contact tongue on the broad side of the base of the contact.
Im übrigen ist vorgesehen, dass der Basissteg des Kontakts zwischen Fassungsstein und Abdeckung fest eingespannt und die Abdeckung ein Spritzgießformteil aus hochtemperaturbeständigem thermoplastischem Kunststoff wie PPS oder LCP ist.Moreover, it is provided that the base bridge of the contact between frame and cover firmly clamped and the Cover an injection molded part made of high temperature resistant thermoplastic material such as PPS or LCP.
Eine Fassung, bei der eine im wesentlichen U-förmige Haltefeder zum fassungssteininternen Angriff mittels seiner Schenkel am Sockel der Lampe vorgesehen ist, kann besonders einfach montiert werden, wenn entsprechend weiterer Ausgestaltung die Abdeckung mit wenigstens einer bodenseitigen Öffnung zum Durchgriff der Schenkel der Haltefeder und zur Aufnahme des Steges der Haltefeder versehen ist, der Steg an seinen Enden mit nach auswärts gerichteten Lappen versehen ist, die sich unter der Abdeckung abstützen, wobei die Schenkel der Haltefeder mittels widerhakenartiger Rastzungen im Fassungsstein verankert sind und Fassungsstein und Abdeckung mittels dieser Haltefeder miteinander verbunden sind. Dabei können ferner die Lappen federnd ausgebildet oder angeordnet sein und auf die Schenkel der Haltefeder Zugkräfte ausüben, die die widerhakenartigen Rastzungen gegen Anlageflächen des Fassungssteins belasten.A socket in which a substantially U-shaped retaining spring to the inside stone attack by means of his thighs on Socket of the lamp is provided, especially easy to mount be, if according to further embodiment, the cover with at least one bottom-side opening for the passage of the Leg of the retaining spring and for receiving the web of the retaining spring is provided, the web at its ends with outwardly directed Lobe is provided, which are supported under the cover, wherein the legs of the retaining spring means of barb-like locking tongues in Masonry stone are anchored and socket stone and cover means This retaining spring are connected together. It also can the tabs are resiliently formed or arranged and on the Legs of the retaining spring exert tensile forces that are barb-like Load locking tongues against bearing surfaces of the socket stone.
Hier ist besonders hervorzuheben, dass allein die Haltefeder die Fassungsbauteile in ihrer bestimmungsgemäßen Position zusammenhält, so dass keinerlei besondere Befestigungsorgane oder Verbindungsmittel wie Nieten od. dgl. erforderlich sind.Here is particularly to emphasize that only the retaining spring the Holding the frame components in their intended position, so no special fasteners or fasteners like rivets od. Like. Required.

einem Fassungsstein 11 und einer leiteranschlussseitigen Abdeckung
12. Der Fassungsstein 11 ist aus temperaturfestem Material gefertigt,
insbesondere aus Keramik oder Porzellan. Gleichwohl könnten auch
Kunststoffmaterialien vergleichbarer Eigenschaften verwendet werden.
Die Abdeckung 12 ist ein spritzgegossenes Formteil aus einem Material,
welches äußerst maßhaltig ist. Als bevorzugte Werkstoffe kommen
hier thermoplastische Kunststoffe wie insbesondere PPS
(Polyphenyl-sulfid) und LCP (Liquid Crystal Polymer) in Betracht.In the drawings is a lamp holder for in particular
Halogen high-voltage lamps, namely those with sockets G9, in total
denoted by 10. The version 10 is in two parts; it consists of
a
Der Fassungsstein 10 weist eine Einstecköffnung 13 zur Aufnahme
des Sockels 30a einer Halogen-Hochvoltlampe 30 (s. Fig. 7)
auf. Mit 14 sind seitliche Nuten bezeichnet zur Aufnahme von Schenkeln
15 einer Haltefeder 16 (Fig. 4).The socket stone 10 has an
Die Haltefeder 16 hat zunächst den Zweck, mit nahe ihren
freien Enden zueinander weisenden Klemmzonen 23, die am Sockel
30a der Lampe 30 angreifen, die Lampe 30 gegen Herausfallen aus
der Fassung 10 zu sichern. Des weiteren kommt der Haltefeder 16 die
Aufgabe zu, den Fassungsstein 11 und die Abdeckung 12 zusammenzuhalten.
Hierzu weisen die beiden Schenkel 15 der Haltefeder 16
ausgeschnittene und nach außen ausgebogene widerhakenartige
Rastzungen 24 und im Bereich des zentralen Steges 25 der Haltefeder
16 nach außen vorstehenden Lappen 26 auf.The retaining
Um die Haltefeder 16 in ihre bestimmungsgemäße Position zu
bringen, werden ihre beiden Schenkel 15 von der Unter- bzw. Leiteranschlussseite
der Abdeckung 12 her durch dessen zentrale Öffnung
20 eingesteckt, bis die diese Öffnung 20 seitlich überragenden Lappen
26 unter dem Boden 19 der Abdeckung 12 zur Anlage gelangen. In
dieser Position stützen sich die widerhakenartigen Rastzungen 24 im
Innern des Fassungssteins 11 jeweils auf einer mit 27 bezeichneten
Schulter ab. Jetzt ist die Haltefeder 16 in der Fassung 10 unverlierbar
gehalten und hält zugleich die beiden Fassungsteile - den Fassungsstein
11 und die Abdeckung 12 - zusammen.To the retaining
Wie des weiteren aus den Fig. 2 und 3 ersichtlich ist, weist der
Fassungsstein 11 an seiner zur Abdeckung 12 weisenden Stirnseite
mit 21 bezeichnete Fügeflächen auf, denen komplementäre Fügeflächen
22 gegenüberstehen, welche an der zum Fassungsstein 11 weisenden
Stirnseite der Abdeckung 12 ausgebildet sind. Diese Fügeflächen
21 und 22 dienen dazu, den Fassungsstein 11 und die
Abdeckung 12 bei gegenseitiger axialer Anlage undrehbar zueinander
zu halten.As further shown in FIGS. 2 and 3 can be seen, the
In der Abdeckung 12 sind Aufnahmekammern 18 zur lagegerechten
sowie wenigstens vorfixierten Halterung von Kontakten 31 (s.
Fig. 5 bis 7) vorgesehen, die die abisolierten Leiterenden 32 mit den
Sockelkontakten 34 der Lampe 30 verbinden. Bei dem gezeigten
Ausführungsbeispiel sind die abisolierten Leiterenden 32 mit angecrimpten
Aderendhülsen 33 versehen. Die abisolierten Leiterenden 32
mit den Aderendhülsen 33 - nachfolgend nur noch kurz als Leiterenden
32 bezeichnet - stecken, wie aus Fig. 6 ersichtlicht, in Sacköffnungen
35 des Fassungssteins 11. Die Sacköffnungen 35 begrenzen
automatisch die Einstecktiefe der Leiterenden 32.In the
Wie aus den Fig. 5 und 6 ersichtlich ist, weist jeder Kontakt 31
im wesentlichen eine U-Form auf mit einem Basissteg 36 und zwei
außenseitigen U-Schenkeln 37. Diese Schenkel 37 sind Bestandteil
jeweils einer schraubenlosen Anschlussklemme, deren wesentlicher
Bestandteil ein Klemmfederabschnitt 38 ist, zu dem der Schenkel 37
einen Widerlagerschenkel ausbildet. Fig. 6 zeigt sehr gut, dass das
abisolierte Ende 32 eines Leiters 39 in der Anschlusslage zwischen
dem Klemmfederabschnitt 38 und dem Widerlagerschenkel 37 eingespannt
ist.As can be seen from FIGS. 5 and 6, each
Im Rahmen der Erfindung ist es wesentlich, dass der Widerlagerschenkel
37 in die erwähnte Sacköffnung 35 eintaucht. Außerdem
stützt er sich, ggf. unter Eigenfederspannung, an der Wand der Sacköffnung
35 ab. Der Klemmfederabschnitt 38 ist von einer Schrägfläche
40 flankiert, die ihm als Anschlagfläche dient, damit er nicht überdehnt
werden kann.In the context of the invention, it is essential that the
Wie im übrigen ersichtlich ist, ist der Klemmfederabschnitt 38
aus dem ebenen Basisabschnitt 36 des Kontakts 31 ausgeschnitten
und aus der Ebene des Basisschenkels 31 ausgebogen.As can be seen otherwise, the clamping
Wie bei Lampenfassungen 10 der in Rede stehenden Art allgemein
üblich, weist jeder Kontakt 31 zwei schraubenlose Anschlussklemmen
auf, jeweils eine an jedem Ende.As with lamp holders 10 of the type in question in general

Die Fig. 5 und 7 zeigen, dass an jedem Kontakt 31, und zwar an
der Längsseite des Basisstegs 36, noch ein weiterer Schenkel 41
angeschnitten und aus der Ebene des Basisstegs 36 herausgebogen
ist. Bei diesem Schenkel 41 handelt es sich um den Kontaktzunge für
einen Sockelkontakt 34 der Lampe 30 (vgl. Fig. 7).Figs. 5 and 7 show that at each
