Description

Titel : Hochdruckentladungslampe mit Zündhilfe Title: High pressure discharge lamp with ignition aid
Technisches Gebiet Technical area
Die Erfindung geht aus von einer Hochdruckentladungslampe gemäß dem Oberbegriff des Anspruchs 1. Derartige Lampen sind insbesondere Hochdruckentladungslampen für Allgemeinbeleuchtung oder für fotooptische Zwecke. The invention relates to a high-pressure discharge lamp according to the preamble of claim 1. Such lamps are in particular high-pressure discharge lamps for general lighting or for photo-optical purposes.
Stand der Technik Aus der US 6 268 698 ist eine Hochdruckentladungslampe mit Entladungsgefäß bekannt, bei der eine Zündhilfe von einem langen Gestelldraht ausgeht. Die Zündhilfe ist ein separates Bauteil, das sich in Höhe einer Kapillare in Richtung des Entladungsgefäßes erstreckt. Nachteilig an einer derartigen Anordnung ist, dass die Zündhilfe aufwendig und kostenträchtig installiert werden muss . PRIOR ART US Pat. No. 6,268,698 discloses a high-pressure discharge lamp with discharge vessel, in which an ignition aid starts from a long frame wire. The ignition aid is a separate component which extends in the direction of the discharge vessel at the level of a capillary. A disadvantage of such an arrangement is that the ignition must be installed consuming and costly.
Darstellung der Erfindung Presentation of the invention
Die Aufgabe der vorliegenden Erfindung ist es, eine Hochdruckentladungslampe bereitzustellen, deren Zündung mit einfachen kostengünstigen Mitteln sichergestellt ist. Dies gilt insbesondere für Metallhalogenidlampen, wobei das Material des Entladungsgefäßes Keramik sein kann. The object of the present invention is to provide a high-pressure discharge lamp whose ignition is ensured by simple inexpensive means. This applies in particular to metal halide lamps, wherein the material of the discharge vessel may be ceramic.
Diese Aufgabe wird gelöst durch die kennzeichnenden Merk¬ male des Anspruchs 1. Besonders vorteilhafte Ausgestaltungen finden sich in den abhängigen Ansprüchen. Erfindungsgemäß wird jetzt ein separates Bauteil am Ge¬ stell verwendet, das sich in Richtung einer Kapillare er¬ streckt. Das Bauteil setzt an der langen Stromzuführung, dem sog. Bügeldraht des Gestells, an, und zwar bevorzugt in einem Bereich in der Nähe der Kapillare, insbesondere wo die Elektrode in der Kapillare sitzt, aber von der Wand der Kapillare beabstandet ist. This object is solved by the characterizing features of claim 1. ¬ male Particularly advantageous configurations are given in the dependent claims. According to the invention a separate component on Ge is now used ¬ alternate he stretches ¬ toward a capillary. The component is connected to the long power supply, the so-called. Stirrup wire of the frame, and preferably in an area in the vicinity of the capillary, in particular where the electrode is seated in the capillary, but is spaced from the wall of the capillary.
Mit zunehmender Lebensdauer steigt die notwendige Spannung zur Zündung von Hochdruckentladungslampen an. Dies kann dazu führen, dass alte Lampen an konventionellen Zündgeräten nicht mehr starten. Die Zündfähigkeit muss jedoch über die gesamte Lebensdauer gewährleistet sein, was durch die erfindungsgemäße Anordnung sichergestellt wird, ohne dass nennenswerte Zusatzkosten entstehen. Bisher gab es dafür verschiedene Lösungsansätze. a) Dem Brennerfüllgas wird ein radioaktives Gas, bei¬ spielsweise Kr85, beigemischt. Die Radioaktivität bewirkt eine Ionisierung des Füllgases, welche die Durchschlags¬ spannung herabsetzt und so die Zündfähigkeit sicher- stellt. Jedoch wird der Gebrauch von Radioaktivität ge¬ setzestechnisch zunehmend eingeschränkt. b) Im Außenkolben wird ein sog. UV-Enhancer eingebaut. Dieser besteht aus einer miniaturisierten Entladungsröhre, die beim Anlegen der Zündspannung UV-Strahlung emit- tiert. Diese UV-Strahlung bewirkt ebenfalls eine Ionisie¬ rung des Brennerfüllgases und stellt so die Zündfähigkeit sicher, siehe EP-A 922296. c) Vom Bügeldraht wird ein Draht um die Kapillare mit der gegenpoligen Elektrode gewickelt. Beim Anlegen der Zünd- spannung entsteht so im Bereich dieser Elektrode eine dielektrisch behinderte Entladung, welche das Brennerfüllgas ionisiert und die Zündspannung herabsetzt, siehe z.B. EP-A 967631. Die jetzige Anordnung greift das Prinzip der dielektrisch behinderten Entladung auf, verbessert es jedoch entscheidend . As the service life increases, the voltage required to ignite high pressure discharge lamps increases. This can result in old lamps not starting on conventional ignitors. However, the ignitability must be guaranteed over the entire lifetime, which is ensured by the arrangement according to the invention, without significant additional costs. So far, there have been various approaches to this. a) The Brennerfüllgas a radioactive gas, in ¬ example Kr85, admixed. Radioactivity causes ionization of the filling gas, which reduces the breakdown voltage ¬, thus ensuring the ignition capability ensured. However, the use of radioactivity is ge ¬ put technically increasingly restricted. b) A so-called UV enhancer is installed in the outer bulb. This consists of a miniaturized discharge tube, which emits UV radiation when the ignition voltage is applied. This UV radiation also causes a Ionisie ¬ tion of Brennerfüllgases and so the ignitability is safe, see EP-A 922,296th c) a wire is wound around the capillary with opposite polarity electrode from the clip wire. When applying the ignition voltage arises in the region of this electrode a dielectrically impeded discharge, which ionizes the Brennerfüllgas and reduces the ignition voltage, see eg EP-A 967631. The present arrangement takes up the principle of dielectrically impeded discharge, but it improves significantly.
Der Bügeldraht ist so gestaltet, dass eine Zündhilfe von dort möglichst nahe zur Kapillare mit der gegenpoligen Elektrode verläuft bzw. diese berührt. Dort entsteht, ähnlich wie bei den unter c) genannten Drahtwicklungen, eine dielektrische behinderte Entladung, die das Füllgas im Brenner ionisiert und einen Durchschlag ermöglicht. Kennzeichnend für den Lösungsansatz ist, dass im Gegen- satz zu bisherigen Lösungen die Zündhilfe ein plattenartiges Metallteil ist. Das Metallteil ist insbesondere ei¬ ne Folie oder ein Blechteil, insbesondere auch ein Feder¬ teil. Eine typische Größe für Folie oder Blechteil ist ein Rechteck mit einer Abmessung von 1 mm x 10 mm. In einem bevorzugten Ausführungsbeispiel wird am Bügel¬ draht und oder der Kapillare eine Metallfolie, bevorzugt aus Molybdän oder Wolfram, mechanisch aufgesteckt, welche die Kapillare mit der Elektrode mit dem entgegengesetzten Potential berührt. Dort entsteht, ähnlich wie bei den un- ter c) genannten Drahtwicklungen, eine dielektrische behinderte Entladung, die das Füllgas im Brenner ionisiert und einen Durchschlag ermöglicht. The hanger wire is designed so that an ignition aid from there as close as possible to the capillary with the opposite pole electrode or touches them. There arises, similar to the wire windings mentioned under c), a dielectric barrier discharge, which ionizes the filling gas in the burner and allows a breakdown. Characteristic of the approach is that in contrast to previous solutions, the Zündhilfe is a plate-like metal part. The metal part is in particular ei ¬ ne film or sheet metal part, in particular a spring ¬ part. A typical size for foil or sheet metal part is a rectangle with a dimension of 1 mm x 10 mm. In a preferred embodiment, a metal foil, preferably made of molybdenum or tungsten, mechanically attached to the bracket ¬ wire and or the capillary, which touches the capillary with the electrode with the opposite potential. There, similar to the wire windings mentioned under c), a dielectrically impeded discharge is produced which ionizes the filling gas in the burner and permits breakdown.
Kennzeichnend für diesen Lösungsansatz ist die Verwendung einer flexiblen Folie, die aufgrund ihrer Nachgiebigkeit stets Kontakt mit der Kapillare des Entladungsgefäßes hat. Hierfür muss die Folie sehr dünn sein, auf jeden Fall dünner als 200 ym, bevorzugt zwischen 20 ym und 40 ym. Die Folie hat keine mechanische Stützwirkung. Sie überdeckt die Kapillare großflächig. Die Folie kann anliegen, die Kapillare partiell oder vollständig überdecken oder die Kapillare umschlingen. Characteristic of this approach is the use of a flexible film, which always contact due to their compliance with the capillary of the discharge vessel Has. For this, the film must be very thin, in any case thinner than 200 ym, preferably between 20 ym and 40 ym. The film has no mechanical support. It covers the capillary over a large area. The film can rest, partially or completely cover the capillaries or loop around the capillaries.
Die Folie wird am Bügeldraht und/oder an der Kapillare entweder Stoffschlüssig (z. B. durch Schweißverfahren) oder kraftschlüssig (z. B. durch Klemmen oder Krimpen) befestigt. The film is fastened to the hanger wire and / or to the capillary either in a material-locking manner (eg by welding) or in a force-fitting manner (eg by clamping or crimping).
Die Folie kann in Bezug auf die Kapillare insbesondere mit der Spitze anliegen, tangential überlappen oder die Kapillare umschlingen. Bevorzugt ist eine möglichst ein¬ fache Geometrie, die die Herstellung nicht beeinträch- tigt. In particular, the foil can lie with the tip in relation to the capillary, overlap tangentially or wrap around the capillary. Preferred is a possible ¬ a fold geometry not taken impair the production.
Die Zündhilfe weist bevorzugt einen geringsten Abstand zur gegenpoligen stromführenden Elektrode auf, wobei der Ort des geringsten Abstands möglichst in der Nähe des ei¬ gentlichen Entladungsgefäßes liegen sollte. The ignition aid preferably has a minimum distance to the opposite pole current-carrying electrode, wherein the location of the smallest distance should be as close as possible to the ei ¬ tual discharge vessel.
Es werden erfindungsgemäß keine radioaktiven Beimischungen mehr benötigt. Eine an der Kapillare geführte Folie ist bei einseitig gesockelten Lampen fertigungstechnisch sehr einfach zu realisieren und zwar wesentlich einfacher als eine Drahtumwicklung der Kapillare. Außerdem benötigt die Folie im Gegensatz zu UV-Enhancern kaum zusätzlichen Platz in Außenkolben. Das Risiko, dass die Zündhilfe auf¬ grund einer schlechten Fügeverbindung zum Bügeldraht während der Lebensdauer seine Funktionalität oder Lage ver- liert, ist praktisch nicht gegeben, da eine Folie relativ großflächig befestigt werden kann. There are according to the invention no more radioactive admixtures needed. A guided on the capillary film is manufacturing technology very easy to implement in one-capped lamps and much easier than a wire wrapping the capillary. In addition, unlike UV enhancers, the film requires little additional space in outer bulbs. The risk that the ignition aid comparable to ¬ fundamentally a bad joint connection to the temple wire during the life of its functionality or location Lier, is practically not given, since a film can be attached over a relatively large area.
Eine an der Kapillare befestigte Folie ist bei einseitig gesockelten Lampen fertigungstechnisch sehr einfach zu realisieren; wesentlich einfacher als eine Drahtumwicklung der Kapillare. Außerdem benötigt diese Folie im Ge¬ gensatz zu UV-Enhancern keinen zusätzlichen Platz in Außenkolben . A film attached to the capillary is very easy to realize in terms of manufacturing technology in single-ended lamps; much easier than a wire wrap the capillary. In addition, this film requires no additional space in the outer bulb in Ge ¬ contrast to UV-enhancers.
Die Folie kann auch beschichtet oder dotiert sein. Eine Folie kann gut geknickt werden und bleibt danach trotzdem formstabil. Sie kann jedoch auch durch geschickte geeignete Anordnung formstabil erhalten werden. The film may also be coated or doped. A film can be kinked well and still remains dimensionally stable thereafter. However, it can also be obtained dimensionally stable by skillful suitable arrangement.
Der Bügeldraht und die Kapillare mit der gegenpoligen Elektrode werden insbesondere durch einen Metallclip ver- bunden. Dieser Clip bewirkt, wie oben erläutert, eine dielektrisch behinderte Entladung, die die Zündspannung herabsetzt. Der Clip besteht bevorzugt aus einer vorgebo¬ genen Metallfolie. Die Form ist so gewählt, dass der Clip durch Vorspannung stabil eng auf der Kapillare und / oder dem Bügeldraht anliegt. The stirrup wire and the capillary with the opposite pole electrode are in particular connected by a metal clip. This clip causes, as explained above, a dielectrically impeded discharge, which reduces the ignition voltage. The clip is preferably made of a vorgebo ¬ genes metal foil. The shape is chosen so that the clip rests tightly by prestressing tightly on the capillary and / or the hanger wire.
Es gibt verschiedene Möglichkeiten, den Clip anzubringen: There are several ways to attach the clip:
Erstes Ausführungsbeispiel: Der Clip wird auf die Kapil¬ lare aufgesteckt (Bild 5.1 und 5.2), wo er durch seine Vorspannung stabil aufliegt. Dabei muss das vorgebogene Metallteil einen Durchmesser aufweisen, der kleiner ist als der Außendurchmesser der Kapillare. Der Durchmesser sollte 70% - 90% des Kapillardurchmessers betragen. Die Verbindung mit dem Bügeldraht muss auf andere Weise er¬ folgen, z.B. durch Schweißen oder Crimpen. Zweites Ausführungsbeispiel: Der Clip wird auf den Bügel¬ draht aufgesteckt. Auch hier muss die Vorformung einen kleineren Durchmesser als der Bügeldraht aufweisen, idealer weise zwischen 70% und 90%. Der Clip muss an der Ka- pillare befestigt werden. Dies kann dadurch geschehen, dass die Metallfolien auf der dem Bügeldraht gegenüberliegenden Seite zusammengefügt werden, z.B. durch Schwei¬ ßen oder Crimpen. First exemplary embodiment: The clip is attached to the capillary (FIGS. 5.1 and 5.2), where it rests stably due to its bias. In this case, the pre-bent metal part must have a diameter which is smaller than the outer diameter of the capillary. The diameter should be 70% - 90% of the capillary diameter. The connection with the clip wire must in other ways he ¬ follow, for example by welding or crimping. Second embodiment: The clip is attached to the bracket ¬ wire. Again, the preforming must have a smaller diameter than the hanger wire, ideally between 70% and 90%. The clip must be attached to the capillary. This can be achieved, that the metal foils are joined together on the opposite side of the bail wire, for example by welding or crimping ¬ SEN.
Drittes Ausführungsbeispiel: Der Clip wird beidseitig gestaltet, d.h. er kann auf Kapillare und Bügeldraht auf¬ gesteckt werden (Bild 5.3 und 5.4) . Dies kann während des Baus des Lampengestells geschehen. Als Variante kommt ei¬ ne Feder zwischen den beiden Enden des Clips in Frage. Mit dieser Konstruktion kann der Clip auf ein fertiges Lampengestell von beiden Seiten aufgesteckt werden. Third Embodiment: The clip is designed on both sides, ie it can be inserted in the capillary and on the clip wire ¬ (Figure 5.3 and 5.4). This can be done during the construction of the lamp frame. As a variant comes ei ¬ ne spring between the two ends of the clip in question. With this construction, the clip can be attached to a finished lamp frame from both sides.
Der Clip kann durch jedes hitzebeständige und elektrisch leitfähige Material hergestellt werden. Erprobt ist die Herstellung aus Molybdän, auch andere Materialien wie verschiedene Stähle sind denkbar. Spezielle Vorteile sind: Es werden keine radioaktiven Beimischungen mehr benötigt. Der Clip benötigt im Gegensatz zu UV-Enhancern keinen zusätzlichen Platz in Außenkolben. Die Realisierung der Fertigung ist sehr einfach, da im Fall von einseitigen Clips nur eine weitere Verbin- dung, z.B. Schweißpunkt, bei beidseitigen Clips keine weitere Verbindungstechnik benötigt wird. Der mechanische Kontakt ist durch die Vorspannung des Clips immer gege¬ ben . The clip can be made from any heat resistant and electrically conductive material. Tried and tested is the production of molybdenum, and other materials such as various steels are conceivable. Special advantages are: No more radioactive admixtures are needed. In contrast to UV enhancers, the clip does not require any additional space in outer bulbs. The realization of the production is very simple, since in the case of one-sided clips only one further connection, eg welding point, with two-sided clips no further connection technology is needed. The mechanical contact is always gege ¬ ben by the bias of the clip.
In einer weiteren Ausführungsform wird der Clip über den Bügeldraht gesteckt, während die Folie an der Seite der Kapillare schließlich verschweißt wird oder anderweitig befestigt wird. In a further embodiment, the clip is placed over the hanger wire, while the film on the side of the Capillary is finally welded or otherwise secured.
Anstatt dass der Clip mit dem Bügeldraht verschweißt wird, ist grundsätzlich auch jede andere Form der dauer- haften Fixierung möglich. Instead of the clip being welded to the stirrup wire, any other form of permanent fixation is possible.

Bevorzugte Ausführungsform der Erfindung Preferred embodiment of the invention
Figur 1 zeigt den Aufbau einer Hochdruckentladungslampe 1 stark schematisiert. Gemäß Figur ld besitzt sie ein Ent¬ ladungsgefäß 2, das in einem Außenkolben 3 untergebracht sind. Die äußeren Zuführungen 4 des Entladungsgefäßes, die Elektroden im Innern kontaktieren, sind mit zwei Gestelldrähten 5 und 6 verbunden. Ein kurzer Gestelldraht 5 führt zu einer ersten Folie 7 in einer Quetschung 8 des Außenkolbens. Ein langer Gestelldraht 6, häufig Bügel- draht genannt, führt zu einer zweiten Folie 7 in der Quetschung 8. Das Entladungsgefäß 2 besitzt an seinen En¬ den jeweils eine Kapillare 10, wie an sich bekannt, sowie eine Füllung, die Metallhalogenide enthält, wie ebenfalls an sich bekannt. Dabei kann Hg enthalten sein, sowie Edelgas. Zwei Elektroden stehen sich im Innern des Entladungsgefäßes gegenüber, wie ebenfalls an sich bekannt, aber hier nicht dargestellt. FIG. 1 shows the structure of a high-pressure discharge lamp 1 in a highly schematic manner. According to FIG. 1 d, it has a discharge vessel 2, which is accommodated in an outer bulb 3. The outer feeds 4 of the discharge vessel, contacting the electrodes inside are connected to two frame wires 5 and 6. A short frame wire 5 leads to a first foil 7 in a pinch 8 of the outer bulb. A long frame wire 6, often called stirrup wire, leads to a second film 7 in the pinch seal 8. The discharge vessel 2 has at its En ¬ each capillary 10, as known per se, and a filling containing metal halides, such as also known per se. It can contain Hg, as well as noble gas. Two electrodes are located in the interior of the discharge vessel, as also known per se, but not shown here.
Der Bügeldraht 6 ist im wesentlichen parallel zur Achse A des Entladungsgefäßes an diesem entlanggeführt zur von der Quetschung 8 entfernten zweiten Kapillare 10. Dort ist er mit der Zuführung 4 verbunden. The hanger wire 6 is guided substantially parallel to the axis A of the discharge vessel at this to the second capillary 10 remote from the pinch seal 8 where it is connected to the feed 4.
Im Bereich der ersten Kapillare 10 ist in Richtung zum Bügeldraht hin eine Folie 11 befestigt, die in etwa rechteckig ausgeschnitten ist. Das Ende 12 der Folie reicht bis zum Bügeldraht 6 und kann dort etwas überste¬ hen . In the region of the first capillary 10, a film 11 is fastened in the direction of the stirrup wire, which is cut out approximately rectangularly. The end 12 of the film extends to the hanger wire 6 and can there something überste ¬ hen.
Im Detail zeigt Figur la die vorgebogene Folie 69 vor dem Befestigen am Entladungsgefäß. Sie hat eine Form ähnlich einer Briefklammer mit einem zentralen Teilkreisbogen 70, der einen Umfang von mehr als 270° umschließt. An das Bo¬ genteil 70 schließen sich zwei zunächst noch freie Schen¬ kel 71 an, die leicht voneinander abgespreizt sind. Diese Schenkel sind so lang, dass sie den Abstand zwischen Ka¬ pillare und Bügeldraht überbrücken. Figur lb zeigt ein Detail des Gestells mit der Kapillare 10. Die Folie 69 ist auf die Kapillare 10 aufgeschoben, so dass das Bogenteil 70 die Kapillare 10 umfasst. Die freien Schenkel zeigen grob in Richtung Bügeldraht, wobei dieser in der Mitte zwischen den Schenkeln sitzt. In detail, Figure la shows the pre-bent foil 69 prior to attachment to the discharge vessel. It has a shape similar to a letter clip with a central pitch arc 70, which encloses a circumference of more than 270 °. On the contrary, Bo ¬ 70 two free kel ¬'s 71 first connect yet which are easily spread apart from one another. These legs are so long that they bridge the distance between Ka ¬ pillar and hanger wire. FIG. 1b shows a detail of the frame with the capillary 10. The foil 69 is pushed onto the capillary 10 so that the arc part 70 comprises the capillary 10. The free legs point roughly in the direction of the hanger wire, which sits in the middle between the thighs.
Figur lc zeigt, dass die freien Schenkel 71 anschließend am Bügeldraht 6 fixiert werden. Sie werden zusammenge¬ drückt und am Bügeldraht 6 verschweißt, so dass die fer¬ tige fixierte Zündhilfe 11 entsteht. In Figur 2 ist ein Ausführungsbeispiel gezeigt, das ähn¬ lich wie in Figur 1 aufgebaut ist. Jedoch ist hier die Folie 69 nicht nach Art einer Briefklammer symmetrisch vorgebogen, sondern nach Art eines deutschen „ß" asymmetrisch einseitig gebogen. Die Folie 69 hat also ein gera- des Schenkelteil 74, von dem tangential ein Bogenteil 75 abgebogen ist. Das Bogenteil ist kreisförmig zurückge¬ führt und dann in Richtung eines Schenkels 76 abgeknickt. Dieser ist gegenüber dem geraden Schenkelteil 74 leicht nach außen gespreizt, doch nahezu parallel zu diesem. Ähnlich wie in Figur 1 wird die Folie 69 auf die Kapilla¬ re aufgesetzt, so dass der Bügeldraht 6 zwischen den bei¬ den Schenkeln 74 und 76 zu liegen kommt, siehe Figur 2b. Dann werden die beiden Schenkel 74 und 76 zusammenge¬ drückt, so dass beide den Bügeldraht 6 von zwei Seiten berühren. Dann werden sie mit dem Bügeldraht 6 verschweißt, so dass die fertige Zündhilfe 11 entsteht. Figure lc shows that the free legs 71 are then fixed to the hanger wire 6. They are pressed together ¬ and welded to the hanger wire 6, so that the fer ¬ term fixed ignition aid 11 is formed. In figure 2 an embodiment is shown which is similarity ¬ Lich constructed as shown in FIG. 1 However, in this case the foil 69 is not bent symmetrically in the manner of a letter staple, but is asymmetrically bent on one side in the manner of a German ".beta .. Thus, the foil 69 has a straight leg part 74, from which an arcuate part tangential tangent 75 is bent circular Retired ¬ leads and then bent in the direction of web 76. this is slightly spread compared with the straight leg portion 74 to the outside, but nearly parallel to this. as in Figure 1, the film is placed on the Kapilla ¬ re 69, so that the Ironing wire 6 the legs comes between the at ¬ 74 and 76 to lie, see Figure 2b. Then, the two legs 74 and 76 together quantitative ¬ suppressed, so that both contact the clip wire 6 from two sides. they are then welded to the clip wire 6 , so that the finished ignition aid 11 is formed.
Figur 3 zeigt ein weiteres Ausführungsbeispiel einer vor¬ gebogenen Folie 80. Diese hat einen ebenen Grundkörper 79, der an beiden Enden eingerollt ist. An einem ersten Ende 81 ist ein erster Teilkreisbogen mit großem Radius vorgebogen. Dieser Radius ist dem Außendurchmesser der Kapillare angepasst. An einem zweiten Ende 82 ist ein zweiter Teilkreisbogen mit kleinerem Radius vorgebogen. Dieser Radius ist dem Bügeldraht-Durchmesser geeignet an- gepasst. Diese Folie 80 kann gleichzeitig an der Kapilla¬ re 10 und am Bügeldraht 6 eingehängt werden, siehe Figur 3b und dann anschließend am Bügeldraht 6 verschweißt wer¬ den. Ggf. reicht die rein mechanische Fixierung bereits aus, so dass ein Verschweißen nicht notwendig ist. Figur 4 zeigt ein weiteres Ausführungsbeispiel einer vor¬ gebogenen Folie 80. Dabei ist die Grundstruktur der Folie, siehe Figur 4a, ähnlich wie in Figur 3. Jedoch ist der eigentlich Folienkörper nicht ausschließlich eine ebene Fläche 85 wie in Figur 3, sondern ein beträchtli- eher Teil 86, bevorzugt 20 bis 80 % der Länge des Grund¬ körpers 79, ist ziehharmonikartig gewellt. Der Grundkör¬ per 79 ist wieder an beiden Enden eingerollt. An einem ersten Ende 81 ist ein erster Teilkreisbogen mit großem Radius vorgebogen. Dieser Radius ist dem Außendurchmesser der Kapillare angepasst. An einem zweiten Ende 82 ist ein zweiter Teilkreisbogen mit kleinerem Radius vorgebogen. Dieser Radius ist dem Bügeldraht-Durchmesser geeignet angepasst. Diese Folie 80 kann gleichzeitig an der Kapilla¬ re 10 und am Bügeldraht 6 eingehängt werden, siehe Figur 4b, und dann ggf. anschließend am Bügeldraht verschweißt werden . FIG. 3 shows a further exemplary embodiment of a pre-bent foil 80. This has a flat main body 79, which is rolled up at both ends. At a first end 81 is a first pitch arc with a large radius pre-bent. This radius is adapted to the outer diameter of the capillary. At a second end 82, a second partial arc with a smaller radius is pre-bent. This radius is suitably adapted to the hanger wire diameter. This film 80 can be simultaneously mounted on the Kapilla ¬ re 10 and the clip wire 6, see figure 3b, and then subsequently welded to the clip wire 6 ¬ the. Possibly. The purely mechanical fixation is already sufficient, so that welding is not necessary. FIG. 4 shows a further exemplary embodiment of a pre-bent film 80. The basic structure of the film, see FIG. 4a, is similar to FIG. 3. However, the actual film body is not exclusively a flat surface 85 as in FIG. rather part 86, preferably 20 to 80% of the length of the base ¬ body 79 is corrugated accordion-like. The Grundkör ¬ per 79 is again rolled at both ends. At a first end 81, a first arc of a large radius is pre-bent. This radius is adapted to the outer diameter of the capillary. At a second end 82, a second partial arc with a smaller radius is pre-bent. This radius is adapted to the hanger wire diameter suitable. This film 80 can be simultaneously mounted on the Kapilla ¬ re 10 and the clip wire 6, see Figure 4b, and then, if necessary, subsequently welded on the clip wire is.
