Definitions
- the invention is concerned with ferrite core halves for the vertical deflection of electron beams in picture tubes, in particular with the attachment of wire guide rings on the ferrite core halves.
- wire guide rings which serve as stops or deflection points due to their shape when winding vertical deflection coils, are firmly connected to at least one edge of the respective ferrite core half.
- This connection is usually designed as an adhesive connection.
- connection of the ferrite core half and the wire guide ring is designed as a solvent diffusion bond.
- Ferrite core halves and wire guide rings connected in this way are realized, for example, in the deflector from Nokia, which bears the designation A 28-5 (460866761).
- This Connection ensures good adhesion of the wire guide ring to the ferrite core half.
- the solvent contains trichlorethylene. The health hazards that can arise from trichlorethylene, as well as the high expenditure on equipment associated with the use of trichlorethylene, need not be dealt with separately here.
- Tolerances between the ferrite core halves and wire guide rings are excluded in solvent dispersion bonding by the connection of ferrite core halves and wire guide rings being pressure-bonded, with a curing time of about 30 to 40 seconds being required.
- wire guide rings and ferrite core halves could also be carried out using two-component adhesives.
- These known adhesives (such as a standard polyurethane adhesive from Wevo, Stuttgart with the designation 801 T) are, on the one hand, very expensive and very expensive to process. In this context, it should only be pointed out that when using two-component adhesives, immense amounts of solvents are required to prevent the adhesive nozzle from sticking.
- Cyanoacrylates as adhesives for connecting wire guide rings to ferrite cores are also known.
- these adhesives for example the cyanoacrylate adhesive from Loctite, Ireland with the designation 380
- cyanoacrylate adhesives require very tight tolerances between the ferrite core and the wire guide ring if fast curing mixtures of this adhesive are used.
- Costs can be met and, moreover, these mixtures tend to penetrate into the porous ferrite core and thereby impair the strength of the adhesive connection itself.
- cyanoacrylate adhesives are used which are more viscous in their consistency and therefore harden more slowly.
- a curing time of about three to four minutes is required, depending on the tolerance between the wire guide ring and the ferrite core. Since the comparatively long curing time of cyanoacrylate adhesives also means that the contact pressure on the wire guide ring or the ferrite core must also act for a long time, large quantities of equipment are required to ensure the pressing times over a period of three to four minutes.
- the invention has for its object to provide a connection of wire guide rings with ferrite core halves, which does not require compliance with close tolerances between the wire guide ring and ferrite core, is physiologically harmless and allows extremely short curing times.
- the adhesive which connects the ferrite core halves and the wire guide rings to one another is a UV-curing adhesive, and in that the wire guide rings are formed from plastic which is transparent to ultraviolet light.
- the adhesive will cure very well even with a short exposure time.
- the adhesive In order to achieve a very good connection between the wire guide ring and the ferrite core half, the adhesive, based on the finished adhesive mixture, must have a weight percentage of 5 to 45 percent of other acrylates in addition to the base material urethane acrylate with a weight percentage between 30 and 50 percent. If these other acrylates are hydroxypropyl acrylate, isobornyl acrylate and methacrylate esters and these other acrylates each have a weight percentage of 5 to 15 percent based on the finished adhesive mixture, very good strength of the connection between wire guide rings and ferrite core halves can be achieved even during fast cycle times during curing. Even with large tolerances of up to 500 »m, optimum connection strength and curing time are achieved when the percentage by weight of the other acrylates in relation to the finished adhesive mixture is the same.
- FIG. 1 shows two ferrite core halves (1) which together form the conical ferrite core of a vertical deflection unit for picture tubes.
- a wire guide ring (3) is glued to the large half circumference (2) of each ferrite core half (1), the wire guide rings (3) covering almost the entire half circumference (2) of the ferrite core halves (1).
- the wire guide rings (3) are made of transparent polycarbonate.
- webs (4) are formed which later serve as deflection points for the vertical deflection coil winding (not shown) when the respective ferrite core half (1) is wound.
- the wire guide rings (3) are glued to the ferrite core halves (1), as shown in FIG. 2.
- the adhesive seam (5) is formed by a UV-curing adhesive, the composition of which is illustrated in the two tables below:
- the proportion of the other acrylates (hydroxypropyl acrylate, isobornyl acrylate and methacrylate ester) are contained in the finished adhesive mixture with approximately the same proportion. Maintaining this ratio between the other acrylates means that the adhesion of the wire guide rings 3 to the ferrite core halves 1 is particularly good. Even wire guide rings 3 and ferrite core halves 1, between which there are tolerances of up to 500 »m, are to be glued together.

Description
Die Erfindung befaßt sich mit Ferritkernhälften zur Vertikalablenkung von Elektronenstrahlen in Bildröhren, insbesondere mit der Befestigung von Drahtführungsringen auf den Ferritkernhälften.The invention is concerned with ferrite core halves for the vertical deflection of electron beams in picture tubes, in particular with the attachment of wire guide rings on the ferrite core halves.
Gemäß dem Stand der Technik sind Drahtführungsringe, welche durch ihre Ausformung beim Bewickeln von Vertikalablenkspulen als Anschläge oder Umlenkpunkte dienen, mit zumindest einem Rand der jeweiligen Ferritkernhälfte fest verbunden. Diese Verbindung ist üblicherweise als Klebeverbindung ausgeführt.According to the prior art, wire guide rings, which serve as stops or deflection points due to their shape when winding vertical deflection coils, are firmly connected to at least one edge of the respective ferrite core half. This connection is usually designed as an adhesive connection.
Gemäß einem bekannten Verbindungsverfahren, ist die Verbindung von Ferritkernhälfte und Drahtführungsring als Lösemitteldiffusionsverklebung ausgeführt. Derart verbundene Ferritkernhälften und Drahtführungsringe sind etwa in dem Ablenker der Firma Nokia realisiert, welcher die Bezeichnung A 28-5 (460866761) trägt. Diese Verbindung gewährleistet eine gute Haftung des Drahtführungsringes auf der Ferritkernhälfte. Nachteilig ist jedoch, daß das Lösemittel Trichloräthylen enthält. Auf die gesundheitlichen Gefahren, die von Trichloräthylen ausgehen können, sowie auf den hohen apparativen Aufwand, der mit dem Einsatz von Trichloräthylen verbunden ist, braucht an dieser Stelle nicht gesondert eingegangen zu werden.According to a known connection method, the connection of the ferrite core half and the wire guide ring is designed as a solvent diffusion bond. Ferrite core halves and wire guide rings connected in this way are realized, for example, in the deflector from Nokia, which bears the designation A 28-5 (460866761). This Connection ensures good adhesion of the wire guide ring to the ferrite core half. However, it is disadvantageous that the solvent contains trichlorethylene. The health hazards that can arise from trichlorethylene, as well as the high expenditure on equipment associated with the use of trichlorethylene, need not be dealt with separately here.
Toleranzen zwischen den Ferritkernhälften und Drahtführungsringen werden bei der Lösemitteldispersionsverklebung dadurch ausgeschlossen, daß die Verbindung von Ferritkernhälften und Drahtführungsringen als Druckverklebung ausgeführt wird, wobei eine Aushärtzeit von etwa 30 bis 40 Sekunden erforderlich ist.Tolerances between the ferrite core halves and wire guide rings are excluded in solvent dispersion bonding by the connection of ferrite core halves and wire guide rings being pressure-bonded, with a curing time of about 30 to 40 seconds being required.
Auch könnte die Verklebung von Drahtführungsringen und Ferritkernhälften mittels zweikomponentiger Klebstoffe ausgeführt sein. Diese an sich bekannten Klebstoffe (etwa ein Polyurethan Standardklebstoff der Firma Wevo, Stuttgart mit Bezeichnung 801 T) sind aber zum einen sehr teuer sowie in der Verarbeitung sehr aufwendig. In diesem Zusammenhang sei nur darauf hingewiesen, daß bei der Verwendung von zweikomponentigen Klebstoffen Unmengen an Lösemitteln erforderlich sind, um ein Verkleben der Klebedüse auszuschließen.The bonding of wire guide rings and ferrite core halves could also be carried out using two-component adhesives. These known adhesives (such as a standard polyurethane adhesive from Wevo, Stuttgart with the designation 801 T) are, on the one hand, very expensive and very expensive to process. In this context, it should only be pointed out that when using two-component adhesives, immense amounts of solvents are required to prevent the adhesive nozzle from sticking.
Cyanacrylate als Klebstoffe für die Verbindung von Drahrführungsringen mit Ferritkernen sind ebenfalls bekannt. Der Einsatz dieser Klebstoffe (etwa der Cyanacrylat-Klebstoff der Firma Loctite, Irland mit der Bezeichnung 380) erfordert aber sehr enge Toleranzen zwischen Ferritkern und Drahtführungsring, wenn schnell härtende Mischungen dieses Klebstoffs verwendet werden. Da die Anforderungen an die Toleranzen von Ferritkernen und die Drahtführungsringen in der Großserienfertigung nur mit unverhältnismäßig großem Kostenaufwand eingehalten werden können und im übrigen diese Mischungen dazu neigen, in den porösen Ferritkern einzudringen und dadurch die Festigkeit der Klebeverbindung an sich beeinträchtigen, werden üblicherweise Cyanacrylatklebstoffe eingesetzt, die von ihrer Konsistenz her zähflüssiger sind und daher langsamer aushärten. Um mittels der langsam aushärtenden Cyanacrylatklebstoffe eine gute Verbindung von Ferritkern und Drahtführungsring zu erreichen, ist je nach Toleranz zwischen Drahtführungsring und Ferritkern eine Aushärtzeit von etwa drei bis vier Minuten erforderlich. Da wegen dieser vergleichsweise langen Aushärtzeit von Cyanacrylatklebstoffen auch die Anpreßkraft auf den Drahtführungsring beziehungsweise den Ferritkern ebenso lange einwirken muß, sind bei großen Stückzahlen hohe apparative Aufwendungen erforderlich, um die Andruckzeiten über den Zeitraum von drei bis vier Minuten zu gewährleisten.Cyanoacrylates as adhesives for connecting wire guide rings to ferrite cores are also known. However, the use of these adhesives (for example the cyanoacrylate adhesive from Loctite, Ireland with the designation 380) requires very tight tolerances between the ferrite core and the wire guide ring if fast curing mixtures of this adhesive are used. Because the requirements for the tolerances of ferrite cores and the wire guide rings in mass production are only disproportionately large Costs can be met and, moreover, these mixtures tend to penetrate into the porous ferrite core and thereby impair the strength of the adhesive connection itself. Usually cyanoacrylate adhesives are used which are more viscous in their consistency and therefore harden more slowly. In order to achieve a good connection of the ferrite core and the wire guide ring by means of the slowly curing cyanoacrylate adhesives, a curing time of about three to four minutes is required, depending on the tolerance between the wire guide ring and the ferrite core. Since the comparatively long curing time of cyanoacrylate adhesives also means that the contact pressure on the wire guide ring or the ferrite core must also act for a long time, large quantities of equipment are required to ensure the pressing times over a period of three to four minutes.
Daher liegt der Erfindung die Aufgabe zugrunde, eine Verbindung von Drahtführungsringen mit Ferritkernhälften anzugeben, die von der Einhaltung enger Toleranzen zwischen Drahtführungsring und Ferritkern nicht erfordert, physiologisch unbedenklich ist und extrem kurze Aushärtzeiten zuläßt.Therefore, the invention has for its object to provide a connection of wire guide rings with ferrite core halves, which does not require compliance with close tolerances between the wire guide ring and ferrite core, is physiologically harmless and allows extremely short curing times.
Diese Aufgabe wird dadurch gelöst, daß der Klebstoff, welcher die Ferritkernhälften und die Drahtführungsringe mit einander verbindet, ein uv-aushärtender Klebstoff ist, und daß die Drahtführungsringe aus Kunststoff gebildet sind, welcher für Ultraviolettes Licht durchlässig ist.This object is achieved in that the adhesive which connects the ferrite core halves and the wire guide rings to one another is a UV-curing adhesive, and in that the wire guide rings are formed from plastic which is transparent to ultraviolet light.
Vorteilhafte Ausbildungen der Erfindung sind in den Ansprüchen 2 bis 6 angegeben.Advantageous embodiments of the invention are specified in
Wird transparentes Polykarbonat als Werkstoff für die Drahtführungsringe verwendet, wird auch bei kurzer Belichtungszeit eine sehr gute Durchhärtung des Klebstoffs erzielt.If transparent polycarbonate is used as the material for the wire guide rings, the adhesive will cure very well even with a short exposure time.
Um eine sehr gute Verbindung von Drahtführungsring und Ferritkernhälfte zu erzielen, muß der Klebstoff bezogen auf die fertige Klebstoffmischung neben dem Basisstoff Urethanacrylat mit einem Gewichtsprozentanteil zwischen 30 und 50 Prozent einen Gewichtsprozentanteil von 5 bis 45 Prozent anderer Acrylate aufweisen. Sind diese anderen Acrylate Hydroxypropylacrylat, Isobornylacrylat und Methacrylatester und weisen diese anderen Acrylate jeweils einen Gewichtsprozentanteil von 5 bis 15 Prozent bezogen auf die fertige Klebstoffmischung auf, läßt sich auch während schneller Taktzeiten beim Aushärten eine sehr gute Festigkeit der Verbindung zwischen Drahtführungsringen und Ferritkernhälften erzielen. Auch bei großen Toleranzen von bis zu 500 »m ist ein Optimum an Verbindungsfestigkeit und Aushärtezeit dann erreicht, wenn der Gewichtsprozentanteil der anderen Acrylate bezogen auf die fertige Klebstoffmischung gleich groß ist.In order to achieve a very good connection between the wire guide ring and the ferrite core half, the adhesive, based on the finished adhesive mixture, must have a weight percentage of 5 to 45 percent of other acrylates in addition to the base material urethane acrylate with a weight percentage between 30 and 50 percent. If these other acrylates are hydroxypropyl acrylate, isobornyl acrylate and methacrylate esters and these other acrylates each have a weight percentage of 5 to 15 percent based on the finished adhesive mixture, very good strength of the connection between wire guide rings and ferrite core halves can be achieved even during fast cycle times during curing. Even with large tolerances of up to 500 »m, optimum connection strength and curing time are achieved when the percentage by weight of the other acrylates in relation to the finished adhesive mixture is the same.

Die in Figur 1 gezeigte Anorndung zeigt zwei Ferritkernhälften (1), die zusammen den konisch ausgebildeten Ferritkern einer vertikalen Ablenkeinheit für Bildröhren bilden. Am großen Halbumfang (2) jeder Ferritkernhälfte (1) ist eine Drahtführungsring (3) angeklebt, wobei die Drahtführungsringe (3) nahezu den gesamten Halbumfang (2) der Ferritkernhälften (1) bedecken. Die Drahtführungsringe (3) sind aus transparentem Polykarbonat gebildet. An der dem Ferritkern abgewandten Seite der Drahtführungsringe (3) sind Stege (4) angeformt, die später beim Bewickeln der jeweiligen Ferritkernhälfte (1) als Umlenkpunkte für die Vertikalablenkspulenwicklung (nicht dargestellt) dienen.The arrangement shown in FIG. 1 shows two ferrite core halves (1) which together form the conical ferrite core of a vertical deflection unit for picture tubes. A wire guide ring (3) is glued to the large half circumference (2) of each ferrite core half (1), the wire guide rings (3) covering almost the entire half circumference (2) of the ferrite core halves (1). The wire guide rings (3) are made of transparent polycarbonate. On the side of the wire guide rings (3) facing away from the ferrite core, webs (4) are formed which later serve as deflection points for the vertical deflection coil winding (not shown) when the respective ferrite core half (1) is wound.
Die Drahtführungsringe (3) sind mit den Ferritkernhälften (1) verklebt, wie Figur 2 näher offenlegt. Die Klebenaht (5) wird von einem uv-aushärtenden Klebstoff gebildet, dessen Zusammensetzung die beiden nachfolgenden Tabellen näher veranschaulichen:
Auffällig bei den beiden Ausführungsbeispielen ist, daß der Anteil der anderen Acrylate (Hydroxypropylacrylat, Isobornylacrylat und Methacrylatester) mit etwa gleichem Anteil in der fertigen Klebstoffmischung enthalten sind. Die Einhaltung dieses Verhältnisses zwischen den anderen Acrylaten führt dazu, daß die Haftung der Drahtführungsringe 3 auf den Ferritkernhälften 1 besonders gut ist. Selbst Drahtführungsringe 3 und Ferritkernhälften 1, zwischen denen Toleranzen bis zu 500 »m bestehen, sind miteinander zu verkleben.It is striking in the two exemplary embodiments that the proportion of the other acrylates (hydroxypropyl acrylate, isobornyl acrylate and methacrylate ester) are contained in the finished adhesive mixture with approximately the same proportion. Maintaining this ratio between the other acrylates means that the adhesion of the wire guide rings 3 to the
