Description

Die Erfindung betrifft eine Halterung für ein ringförmiges und zum Bildschirm hin sich trompetenartig aufweitendes um den Hals einer Kathodenstrahlröhre angeordnetes Ablenkjoch mit einem am aufweitend geöffneten Ende des Ablenkjoches angebrachten Befestigungsteil.The invention relates to a holder for a ring-shaped deflecting yoke which widens like a trumpet and is arranged around the neck of a cathode ray tube and has a fastening part attached to the widened open end of the deflecting yoke.

Die genaue Einhaltung der Lage der Ablenkebene gegenüber dem Elektronenstrahlerzeugersystem und dem Bildschirm wird beispielsweise in einer Kathodenstrahl-Farbbildröhre nach dem Schattenmaskenprinzip verlangt. Bei einer solchen Röhre soll einerseits die Konvergenz der Elektronenstrahlen im Bereich der Schattenmaske erreicht werden und andererseits sind strenge Anforderungen an den Auftreffwinkel des Elektronenstrahls auf die Schattenmaske und den Bildschirm zu erfüllen, um sicherzustellen, daß der jeweilige Elektronenstrahl das ihm zugehörige Farbelement trifft.Precise compliance with the position of the deflection plane with respect to the electron gun system and the screen is required, for example, in a cathode ray color picture tube according to the shadow mask principle. With such a tube, on the one hand the convergence of the electron beams in the area of the shadow mask is to be achieved and on the other hand stringent requirements are imposed on the angle of incidence of the electron beam on the shadow mask and the screen in order to ensure that the respective electron beam hits the color element associated with it.

Da in der Praxis der Herstellung einer solchen Röhre und des dazugehörigen Ablenkjoches mit Ungenauigkeiten gerechnet werden muß, die die Qualität des Bildes über das zulässige Maß beeinträchtigen könnten, hat es sich bewährt, diese Ungenauigkeiten bis zu einem gewissen Grade durch eine nachträgliche Einstellung der Lage des Ablenkjoches auszugleichen.Since in practice the production of such a tube and the associated deflection yoke must be reckoned with inaccuracies that could impair the quality of the image beyond the permissible extent, it has proven to be effective to a certain extent to these inaccuracies by subsequently adjusting the position of the Compensate the deflection yoke.

Hierzu ist die Möglichkeit einer Verschiebung des Ablenkjoches längs und um die Röhrenachse, sowie einer Veränderung der Neigung zur Röhrenachse erwünscht.For this purpose, the possibility of shifting the deflection yoke along and around the tube axis, as well as changing the inclination to the tube axis, is desired.

Aus der DE-OS 24 45 577 ist eine derartig einstellbare Ablenkjochhalterung bekannt, in der das Ablenkjoch am hinteren schmalgeöffneten Ende sich auf den Röhrenhals abstützt, während vorne eine Kugelfläche ein Schwenken des Ablenkjoches um sein hinteres Ende ermöglicht und vorne weitere ineinander steckende Ringe auch eine axiale Verschiebung zulassen. Von Nachteil sind hier die zahlreichen, am vorderen Ende des Ablenkjoches benötigten Teile, die letztlich durch ihre Vielzahl und durch die Notwendigkeit vom Ablenkjoch her Kräfte in allen Richtungen aufnehmen zu müssen, auch relativ stabil ausgebildet sein müssen.From DE-OS 24 45 577 such an adjustable deflection yoke holder is known, in which the deflection yoke on rear narrow-open end is supported on the tube neck, while in front a spherical surface allows the deflection yoke to pivot about its rear end and in the front further nested rings also permit axial displacement. The disadvantage here is the numerous parts required at the front end of the deflection yoke, which ultimately have to be designed to be relatively stable due to their large number and the need to absorb forces in all directions from the deflection yoke.

Aufgabe der Erfindung ist es daher eine einstellbare Ablenkjochhalterung anzugeben, die mit weniger und einfacheren Mitteln die geforderte Einstellung des Ablenkjoches ermöglicht.The object of the invention is therefore to provide an adjustable deflection yoke holder which enables the required adjustment of the deflection yoke with fewer and simpler means.

Die Lösung der Aufgabe ist dadurch gekennzeichnet, daß der am aufweitend geöffneten Ende des Ablenkjoches angebrachte Befestigungsteil mindestens aus zwei Ringen besteht, von denen der erste Ring um das aufweitend geöffnete Ende des Ablenkjoches röhrenaxial verschiebbar, schwenkbar und fixierbar angeordnet und an seiner dem Bildschirm zugewandten Berührungsfläche mit dem zweiten Ring sich kegelförmig aufweitend geformt ist und von denen der zweite Ring, zwischen dem ersten Ring und dem Röhrenkönus angeordnet und fest mit dem Röhrenkonus verbunden ist und an seiner Berührungsfläche mit dem ersten Ring in der Form an diesen angepasst und mit diesem verschiebbar, drehbar und fixierbar verbunden ist.The solution to the problem is characterized in that the fastening part attached to the widened open end of the deflection yoke consists of at least two rings, of which the first ring is arranged to be axially displaceable, pivotable and fixable in a tube-axial manner and on its contact surface facing the screen is conically widened with the second ring and of which the second ring is arranged between the first ring and the tube cone and is fixedly connected to the tube cone and is adapted to the shape of the first ring on its contact surface and displaceable with it, is rotatably and fixably connected.

Die Erfindung läßt sich auch besonders vorteilhaft dort einsetzen, wo bei einer automatisierten Herstellung die Ausrichtung des Ablenkjoches auf der Kathodenstrahlröhre mittels einer von außen direkt an das Ablenkjoch angreifenden Vorrichtung erfolgt, jedoch auch die Möglichkeit einer manuellen Nacheinstellung gegeben seien soll.The invention can also be used particularly advantageously where the automated production Alignment of the deflection yoke on the cathode ray tube takes place by means of a device which acts directly on the deflection yoke from the outside, but the possibility of manual readjustment should also be provided.

In einer bevorzugten Ausführungsform der Erfindung bildet die kegelförmige Berührungsfläche zwischen dem ersten und dem zweiten Ring gegenüber der Röhrenachse einen Winkel von etwa 50-70 Grad.In a preferred embodiment of the invention, the conical contact surface between the first and the second ring forms an angle of approximately 50-70 degrees with respect to the tube axis.

Je nach Form der Auflagefläche für den ersten Ring auf dem Ablenkjoch und der Berührungsfläche zwischen den beiden Ringen, sowie je nach Ausgestaltung der Mittel für die Befestigung der Teile miteinander ist für die Beweglichkeit der Teile untereinander eine gewisse Elastizität wenigstens einiger Teile erforderlich. Um die Anforderungen an diese Elastizität gering zu halten, sieht die weitere Ausgestaltung der Erfindung vor, einerseits die Berührungsfläche zwischen den beiden Ringen als Teilkugelfläche auszubilden und andererseits auch die Fläche des Ablenkjoches, die zur Auflage des ersten Ringes dient, so zu wölben, daß sie eine ringförmige Teilkugelfläche bildet, die in einer durch sie gebildeten Kugelscheibe den Mittelpunkt der zugehörigen Kugel enthält.Depending on the shape of the bearing surface for the first ring on the deflection yoke and the contact surface between the two rings, and depending on the design of the means for fastening the parts to one another, a certain elasticity of at least some parts is required for the mobility of the parts with one another. In order to keep the demands on this elasticity low, the further embodiment of the invention provides, on the one hand, to form the contact surface between the two rings as a partial spherical surface and, on the other hand, to also curve the surface of the deflection yoke that serves to support the first ring so that it forms an annular partial spherical surface which contains the center point of the associated ball in a spherical disk formed by it.

Further details and design options can be found in the following description of exemplary embodiments and the accompanying drawings.
  • Fig. 1 shows a partial section of a deflection yoke holder according to the invention

  • 3, 4 and 5 show possible designs of details of the deflection yoke holder according to FIG. 1
  • Fig. 6 shows the execution of the narrowly opened deflection yoke end as a support part.

Fig. 1 zeigt wie ein Ablenkjoch 4 erfindungsgemäß an seinem aufweitend geöffneten Ende mittels eines ersten Ringes 1 und eines zweiten Ringes 2 am Röhrenkonus 3 befestigt ist. Die beiden Ringe 1 und 2 sind bei gelockerten Verbindungsschrauben 5 in gewissem Umfange gegeneinander beweglich, da die Löcher 1a und 2a für diese Verbindungsschrauben 5 in den Ringen 1 und 2 entsprechend Fig. 3 und 4 als Langlöcher ausgeführt sind. Wird die Berührungsfläche zwischen den Ringen 1 und 2 als ringförmige Kegelteilfläche ausgebildet, so muß wenigstens einer der beiden Ringe 1 und 2 jedoch ausreichend elastisch sein, um beim Verschieben die sich ergebende Verformung ohne großen Kraftaufwand zu vollziehen.1 shows how a deflection yoke 4 is attached to the tube cone 3 at its widened open end by means of a first ring 1 and a second ring 2. The two rings 1 and 2 can be moved to a certain extent when the connecting screws 5 are loosened, since the holes 1a and 2a are designed as elongated holes for these connecting screws 5 in the rings 1 and 2 according to FIGS. 3 and 4. If the contact surface between the rings 1 and 2 is designed as an annular conical partial surface, then at least one of the two rings 1 and 2 must be sufficiently elastic to carry out the resulting deformation without great effort when moving.

Um die erforderliche Verformbarkeit an dieser Stelle zu vermeiden, kann man die Berührungsfläche zwischen den beiden Ringen 1 und 2 auch in eine Ebene senkrecht zur Röhrenachse legen. Dies hat aber den wesentlichen Nachteil, daß ein erheblicher Teil an Formstabilität der Ablenkjochhalterung verloren geht.To avoid the required deformability at this point, the contact surface between the two rings 1 and 2 can also be placed in a plane perpendicular to the tube axis. However, this has the major disadvantage that a considerable part of the dimensional stability of the deflection yoke holder is lost.

In einer Weiterbildung der Erfindung wird daher ein Winkel gegen die Ebene senkrecht zur Röhrenachse beibehalten, jedoch wird die Berührungsfläche zwischen den Ringen 1 und 2 derart gewölbt ausgeführt, daß sie eine ringförmige Teilkugelfläche bildet. Fig. 2 zeigt stark schematisiert die Geometrie der Berührungsflächen der Anordnung. Der mittlere Winkel 12 der Berührungsfläche zwischen den Ringen 1 und 2 und die dazugehörige Kugel 10, aus der die Teilkugelfläche gebildet wird, sind dargestellt. Bei einer derartigen Ausbildung der Ringe 1 und 2 ist bei gegenseitiger Verschiebung keine Verformung an dieser Fläche mehr gegeben. Um auch bei Verkanten des ersten Ringes 1 gegenüber dem Ablenkjoch 4 die Notwendigkeit einer Verformung zu verringern, hat das Ablenkjoch an diesem Ende ebenfalls eine ringförmige Teilkugelfläche 4a, deren wesentliche Geometrie mittels der Kugel 11 in Fig. 2 gezeigt wird.In a further development of the invention, an angle is therefore maintained relative to the plane perpendicular to the tube axis, but the contact surface between the rings 1 and 2 is designed so that it forms an annular partial spherical surface. 2 shows the geometry of the contact surfaces of the arrangement in a highly schematic manner. The mean angle 12 of the contact surface between the rings 1 and 2 and the associated ball 10 from which the partial spherical surface is formed are shown. With such a Formation of rings 1 and 2 is no longer given deformation on this surface with mutual displacement. In order to reduce the need for deformation even when the first ring 1 is tilted relative to the deflection yoke 4, the deflection yoke also has an annular partial spherical surface 4a at this end, the essential geometry of which is shown by means of the ball 11 in FIG. 2.

Am Ablenkjoch 4 wird der erste Ring 1 nach erfolgter Einstellung mit den Schrauben 9 fixiert, für die im Ring 1 Langlöcher in röhrenaxialer Richtung vorgesehen sind, um das Ablenkjoch 4 in dieser Richtung verschieben zu können.On the deflection yoke 4, the first ring 1 is fixed with the screws 9, for which elongated holes are provided in the tube-axial direction in the ring 1 in order to be able to move the deflection yoke 4 in this direction.

Der zweite Ring 2 ist fest mit dem Röhrenkonus 3 verbunden. Dies kann beispielsweise durch Kleben oder über eine, an den Röhrenkonus 3 angeformte Stufe 3a erfolgen. Um einen festen Sitz des Ringes 2 auf der Stufe 3a zu erreichen, kann beispielsweise der Röhrendurchmesser auf der Stufe in Richtung zum Bildschirm sich verringern. Bei entsprechender Gestaltung des Ringes 2 wird dann eine gewisse Kraft nötig sein, um den Ring 2 aufzubringen oder abzunehmen. Um diesen Ring 2 auch gegen Verdrehung um die Röhrenachse zu sichern, kann beispielsweise die Stufe 3a, wie in Fig. 5 gezeigt, eine Keilförmige in den Ring 2 ragende Nase 13 aufweisen. Die Festlegung des schmalgeöffneten Endes des Ablenkjoches 4b auf dem Röhrenhals kann, wie in Fig. 1 gezeigt, in bereits bekannter Weise mit elastischen Laschen 1a und einer Schelle 6 erfolgen, kann aber auch, wenn auf eine stärkere Fixierung dieses Ablenkjochendeu 4b auf dem Röhrenhals verzichtet werden soll, durch einfache , wie in Fig. 6 gezeigt, das Ablenkjochende 4b auf dem Röhrenhals zentrierende, über den Röhrenumfang verteilte, elastische Nasen 7b erfolgen.The second ring 2 is firmly connected to the tube cone 3. This can be done, for example, by gluing or via a step 3a formed on the tube cone 3. In order to achieve a tight fit of the ring 2 on the step 3a, for example the tube diameter on the step can decrease in the direction of the screen. With a corresponding design of the ring 2, a certain force will then be required to apply or remove the ring 2. In order to also secure this ring 2 against rotation about the tube axis, the step 3a, for example, as shown in FIG. 5, can have a wedge-shaped nose 13 projecting into the ring 2. The fixing of the narrowly opened end of the deflection yoke 4b to the tube neck can, as shown in FIG. 1, be carried out in a known manner with elastic tabs 1a and a clamp 6, but can also be done if a stronger fixing of this deflection yoke end 4b to the tube neck is dispensed with 6, the deflection yoke end 4b centering on the tube neck and distributed over the tube circumference is to be provided by simple, as shown in FIG. 6, elastic lugs 7b.
