Description

Die Erfindung betrifft eine Halterung für ein ringförmiges, um den Hals einer Kathodenstrahlröhre angeordnetes und zum Bildschirm hin sich trompetenartig aufweitendes Ablenkjoch mit einem am weiteren Ende des Ablenkjoches angebrachten Befestigungsteil.The invention relates to a holder for a ring-shaped deflection yoke which is arranged around the neck of a cathode-ray tube and widens like a trumpet with a fastening part attached to the further end of the deflection 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, the convergence of the electron beams in the area of the shadow mask is to be achieved on the one hand 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 manufacture of such a tube and the associated deflection yoke must be expected with inaccuracies that could impair the quality of the image beyond the permissible extent, it has proven to be effective to a certain extent 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-A1 24 45 577 ist eine derartig einstellbare Ablenkjochhalterung bekannt, in der das Ablenkjoch am hinteren, engeren 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. Es wird also das weitere Ende des Ablenkjoches um einen im Bereich des engeren Endes liegenden Drehpunkt verschwenkt. 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-A1 24 45 577, such an adjustable deflection yoke holder is known, in which the deflection yoke is supported on the tube neck at the rear, narrower end, while a spherical surface at the front enables the deflection yoke to pivot about its rear end and, at the front, further nested rings allow an axial displacement. The further end of the deflection yoke is thus pivoted about a fulcrum located in the area of the narrower end. A disadvantage here is the numerous parts required at the front end of the deflection yoke, which ultimately also have 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 geschieht dadurch, dass diese Einstellung durch Verschwenken des engeren Ablenkjochendes um einen in Richtung Bildschirm auf der Röhrenachse liegenden Drehpunkt mit Hilfe des am weiteren Ende des Ablenkjoches angebrachten Befestigungsteiles erfolgt, wobei dieses Befestigungsteil aus zwei Ringen besteht, wovon der erste Ring um das weitere Ende des Ablenkjoches angeordnet, gegenüber diesem axial verschiebbar, um diesen schwenkbar und gegenüber diesem fixierbar ist und an seinem, dem Bildschirm zugewandten Ende, einen eine Berührungsfläche mit dem zweiten Ring bildenden, sich gegen den Bildschirm aufweitenden Abschnitt umfasst, und der zweite Ring zwischen dem ersten Ring und dem Röhrenkonus angeordnet, fest mit dem Röhrenkonus verbunden und an seiner Berührungsfläche mit dem ersten Ring in der Form an diesen angepasst ist, wobei die beiden Ringe gegeneinander verschwenkbar und drehbar ausgebildet sind sowie Mittel zur gegenseitigen Fixierung in jeder der möglichen Lagen umfassen.The problem is solved in that this setting is made by pivoting the narrower deflection yoke end about a pivot point lying in the direction of the screen on the tube axis with the aid of the fastening part attached to the further end of the deflection yoke, this fastening part consisting of two rings, of which the first ring the further end of the deflection yoke is arranged, axially displaceable relative to it, pivotable about it and fixable relative to it, and at its end facing the screen comprises a section forming a contact surface with the second ring and widening towards the screen, and the second ring arranged between the first ring and the tube cone, firmly connected to the tube cone and adapted in shape to the first ring at its contact surface, the two rings being pivotable and rotatable relative to one another and means for mutual fixation in each of the possible Layers include.

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 sein soll.The invention can also be used particularly advantageously where, in the case of automated production, the deflection yoke is aligned on the cathode ray tube 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 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 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 Federelastizität wenigstens einiger Teile erforderlich. Um diese Anforderungen an diese Elastizität gering zu halten, sieht die weitere Ausgestaltung der Erfindung vor, einerseits die Berührungsfläche zwischen den beiden Ringen als Kugelzone auszubilden und andererseits auch die Fläche des Ablenkjoches, die zur Auflage des ersten Ringes dient, so zu wölben, dass sie eine Kugelzone bildet, wobei die durch sie gebildete Kugelzonenscheibe den Mittelpunkt der zugehörigen Kugel enthält.Depending on the shape of the contact 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 spring elasticity of at least some parts is required for the mobility of the parts with one another. In order to keep these requirements for this elasticity low, the further embodiment of the invention provides, on the one hand, to design the contact surface between the two rings as a spherical zone and, on the other hand, to curve the surface of the deflection yoke, which is used to support the first ring, so that it forms a spherical zone, the spherical zone disk formed by it containing the center of the associated sphere.

Further details and design options can be found in the following description of exemplary embodiments and the accompanying drawings.

Fig. 1 zeigt, wie ein Ablenkjoch 4 erfindungsgemäss an seinem weiteren 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 1 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 federelastisch sein, um bei gegenseitigem Verschwenken die sich ergebende Verformung ohne grossen Kraftaufwand zu vollziehen.1 shows how a deflection yoke 4 according to the invention is attached to the tube cone 3 at its further end by means of a first ring 1 and a second ring 2. The two rings 1 and 2 are with the connecting screw loosened ben 5 to a certain extent movable against each other, since the holes 1 and 2a for these connecting screws 5 in the rings 1 and 2 according to FIGS. 3 and 4 are designed as elongated holes. 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 resilient in order to carry out the resulting deformation without great effort when pivoting relative to one another.

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 Kugelzone 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, auf der die Kugelzone liegt, sind dargestellt. Bei einer derartigen Ausbildung der Ringe 1 und 2 ist bei gegenseitigem Verschwenken 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 kugelzonenförmige Fläche 4a, deren wesentliche Geometrie mittels der Kugel 11 in Fig. 2 gezeigt wird.In a development of the invention, therefore, an angle is maintained relative to the plane perpendicular to the tube axis, but the contact surface between the rings 1 and 2 is curved so that it forms a spherical zone. 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 on which the ball zone lies are shown. With such a configuration of the rings 1 and 2, there is no longer any deformation on this surface when pivoted relative to one another. 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 a spherical zone-shaped 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.The first ring 1 is fixed on the deflection yoke 4 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 engeren Endes des Ablenkjoches 4b in jeder Schwenklage auf dem Röhrenhals kann, wie in Fig. 1 gezeigt, in bereits bekannter Weise mit federelastischen Laschen 7a und einer Schelle 6 erfolgen, kann aber auch, wenn auf eine stärkere Fixierung dieses Ablenkjoches 4b auf dem Röhrenhals verzichtet werden soll, wie in Fig. 6 gezeigt, durch einfache, das Ablenkjoch 4b auf dem Röhrenhals abstützende, über den Röhrenumfang verteilte, federelastische 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 secure this ring 2 against rotation around the tube axis, for example, the step 3a, as shown in FIG. 5, can have a wedge-shaped nose 13 projecting into the ring 2. The narrower end of the deflection yoke 4b can be fixed in any swivel position on the tube neck, as shown in FIG. 1, in a known manner using spring-elastic tabs 7a and a clamp 6, but can also be done if this deflection yoke 4b is more firmly fixed the tube neck is to be dispensed with, as shown in FIG. 6, by simple, resilient lugs 7b which support the deflection yoke 4b on the tube neck and are distributed over the tube circumference.
