Ablenkeinheiten werden auf eine Elektronenstrahlröhre montiert, um die Elektronenstrahlen über den Bildschirm in X- und Y-Richtung abzulenken. Die Ablenkeinheit besteht im wesentlichen aus zwei Spulenpaaren und einem Ferritkern, der zur Rückführung des magnetischen Flusses dient. Das eine Spulenpaar erzeugt ein Magnetfeld, das die Elektronenstrahlen in horizontale Richtung (X-Richtung) ablenkt, während das andere Spulenpaar der vertikalen Ablenkung (Y-Richtung) dient.Deflection units are mounted on an electron beam tube around the electron beams distract from the screen in the X and Y directions.

Die im Stand der Technik bekannten Justierungen sind jedoch entweder zu ungenau oder erfordern komplexe Vorrichtungen, die die Fertigung einer solchen Ablenkeinheit aufwendig werden lassen.However, the adjustments known in the prior art are either too imprecise or require complex devices to manufacture such a deflector let it become complex.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Ablenkeinheit zur Montage auf eine Farbbild-Elektronenstrahlröhre anzugeben, die eine vereinfachte Positionierung und Justierung der Vertikalspule zuläßt. Des weiteren soll eine entsprechende Farbbild-Elektronenstrahlröhre sowie ein zugehöriges Bildschirmgerät bereitgestellt werden.The invention is therefore based on the object of a deflection unit for mounting to provide a color image cathode ray tube that simplifies positioning and adjustment of the vertical coil. Furthermore, a corresponding color image tube is intended and an associated display device are provided.

Diese Aufgabe wird erfindungsgemäß durch eine Ablenkeinheit zur Montage auf eine Farbbild-Elektronenstrahlröhre gelöst, die einen Spulenkörper für eine Vertikalablenkspule sowie eine erste und zweite Einrichtung zur Verschiebung des Spulenkörpers in eine erste bzw. zweite Richtung umfaßt. Die ersten und zweiten Richtungen sind um etwa 90° versetzt und liegen im wesentlichen parallel zur Bildschirmebene der Farbbild-Elektronenstrahlröhre.This object is achieved by a deflection unit for mounting on a Color image cathode ray tube solved a bobbin for a vertical deflection coil and a first and second means for moving the bobbin in comprises a first and a second direction. The first and second directions are around offset by about 90 ° and are essentially parallel to the screen plane of the color image tube.

Die Erfindung erlaubt in vorteilhafter Weise eine voneinander getrennte Justierung der Position der Vertikalspule in X- und Y-Richtung.The invention advantageously allows separate adjustment of the Position of the vertical coil in the X and Y directions.

Darüber hinaus weist die erfindungsgemäße Ablenkeinheit eine kompakte Bauform auf, so daß sie sich in einfacher Weise auf den Hals einer Farbbild-Elektronenstrahlröhre montieren läßt.In addition, the deflection unit according to the invention has a compact design, so that it can easily be placed on the neck of a color image tube can be assembled.
