Description
Die Erfindung bezieht sich auf eine Spulenanordnung zur Ablenkung von Kathodenstrahlen, die aus zwei symmetrisch zum Röhrenhals liegenden Halbspulen mit je zwei Stirnleitern und zwei Längsleitern besteht, bei denen die Längsleiter auf dem Mantel eines sich in Strahlrichtung öffnenden Pyramidenstumpfes und die Stirnleiter in senkrecht zur Röhrenachse stehenden Ebenen liegen.The invention relates to a coil arrangement for deflecting cathode rays, the consisting of two half-coils symmetrically to the tube neck, each with two frontal conductors and two There is longitudinal conductors, in which the longitudinal conductors on the jacket of an opening in the direction of the beam The truncated pyramid and the frontal ladder lie in planes perpendicular to the tube axis.
Es sind bereits Ablenkspulen bekannt, welche ίο dem rohrförmigen Kolbenhals der Kathodenstrahlröhre angepaßt sind .und somit einen zylinderförmigen Raum umschließen. Es ist auch vorgeschlagen worden, Spulen zu verwenden, deren Längsleiter auf einer pyramiden- bzw. kegelstumpfförmigen Fläche liegen.Deflection coils are already known which ίο the tubular bulb neck of the cathode ray tube are adapted .and thus enclose a cylindrical space. It is also suggested been to use coils, the longitudinal conductor on a pyramidal or truncated cone Area.
Bei derartigen Anordnungen, bei denen die Spulenanordnung aus zwei symmetrisch zum Röhrenhals liegenden Halbspulen mit je zwei Stirnleitern und zwei Längsleitern besteht und bei der die Stirnleiter in senkrecht zur Röhrenachse stehenden Ebenen liegen, soll gemäß der Erfindung der Wickelquerschnitt der Längsleiter größer sein als der Wickelquerschnitt der Stirnleiter und vorzugsweise in Strahlrichtung zunehmen. Zweckmäßigerweise sind zwischen den einzelnen Wicklungslagen des Längsleiters keilförmige Isolierstreifen angeordnet. Da hierbei die Spulen einen in Strahlrichtung sich erweiternden Raum umschließen, ergibt sich der Vorteil, daß eine Ablenkung über beträchtliche Winkelöffnungen möglich ist, die mit besonders kleinen Verlusten bewirkt werden kann, da sich eine Spule besonders kleiner Induktivität ergibt. Da ferner die Längsleiter einen größeren Wickelquerschnitt haben als die Stirnleiter und der Wickelquerschnitt der Längsleiter in Strahlrichtung zunimmt, wird trotz des Querschnittsunterschiedes der Spule beim Eintritt und beim Austritt des Strahls ein nahezu gleichmäßiges Feld auf der ganzen vom Strahl durchlaufenen Ablenklänge gewährleistet. Dadurch kann die Verzerrung trotz der größeren Ablenkwinkel klein gehalten werden.In such arrangements in which the coil arrangement consists of two symmetrical to Tubular neck lying half-coils with two front conductors each and two longitudinal conductors and in which the end conductor is perpendicular to the tube axis Lay planes, should be greater than the winding cross-section of the longitudinal conductor according to the invention the winding cross-section of the end conductor and preferably increase in the direction of the beam. Appropriately wedge-shaped insulating strips are arranged between the individual winding layers of the longitudinal conductor. Since the coils enclose a space that widens in the direction of the beam, this results the advantage that a deflection over considerable angular openings is possible, which with particularly small losses can be caused, since a coil has a particularly small inductance results. Furthermore, since the longitudinal conductors have a larger winding cross-section than the end conductors and the winding cross-section of the longitudinal conductor increases in the beam direction, despite the cross-sectional difference of the coil at the entrance and at When the beam emerges, an almost uniform field is guaranteed over the entire deflection length traversed by the beam. This can reduce the distortion can be kept small despite the larger deflection angle.
Nachstehend wird die Erfindung an Hand der ein Ausführungsbeispiel darstellenden Figuren beschrieben. The invention is described below with reference to the figures representing an exemplary embodiment.
Fig. ι zeigt ein Spulenpaar in schaubildlicher Ansicht, währendFig. Ι shows a coil pair in a perspective view, while
Fig. 2 eine Abwicklung einer Spule darstellt. Die oberen Stirnleiter 1 und die unteren Stirnleiter 2 jeder Spule verbinden die Längsleiter 3Fig. 2 shows a development of a coil. The upper front ladder 1 and the lower front ladder 2 of each coil connect the longitudinal conductors 3
und 4. Die Spulenanordnung wird auf dem Röhrenhals einer Kathodenstrahlröhre so angeordnet, daß die engere Seite auf der Strahleintrittsseite liegt.and 4. The coil assembly is placed on the tube neck of a cathode ray tube so that the narrower side is on the beam entry side.
Die Spulen werden bei der Herstellung zweckmäßig als Flachspulen nach Fig. 2 über einen Dorn mit trapezförmigem Querschnitt gewickelt. Die Ausbuchtung der Stirnleiter 2 ist erforderlich, damit die gekröpften Stirnleiter etwa in der zur Röhrenachse senkrechten Ebene liegen. Der Querschnitt der Längsleiter an der Strahleintrittsseite ist kleiner als der an der Strahlaustrittsseite. Dies wird zweckmäßig durch zwischen den einzelnen Wi'cklungslagen eingelegte keilförmige Isolierstreifen erreicht.The coils are expediently manufactured as flat coils according to FIG. 2 over a mandrel wound with a trapezoidal cross-section. The bulge of the front conductor 2 is necessary so the cranked frontal conductors are roughly in the plane perpendicular to the tube axis. The cross section the longitudinal conductor on the beam entry side is smaller than that on the beam exit side. this is expedient by means of wedge-shaped insulating strips inserted between the individual wrapping layers achieved.
Es können zwei oder vier derartige Halbspulen auf einem Tragkörper in Form eines quadratischen Pyramidenstumpfes aufgebracht werden, der mit einer konischen oder zylindrischen axialen Bohrung versehen ist. Bei Verwendung von vier Spulen werden diese so angeordnet, daß das eine der Spulenpaare zwischen den gekröpften Stirnleitern des anderen Spulenpaares zu liegen kommt, so daß die Längsleiter der beiden Spulenpaare den Mantel eines Pyramidenstumpfes bilden. Als Material für dem Spulenkörper wird z. B. Isolierpreßstoff verwendet. Das Material wird in pulVerförmigem Zustand unter Druck und Hitze in die gewünschte Form des Spulenträgers gepreßt.There can be two or four such half-coils on a support body in the form of a square Truncated pyramids are applied with a conical or cylindrical axial bore is provided. When using four coils they are arranged so that one of the Coil pairs come to lie between the cranked end conductors of the other coil pair, so that the longitudinal conductors of the two pairs of coils form the jacket of a truncated pyramid. As a material for the bobbin is z. B. Isolierpreßstoff used. The material is in powder form pressed under pressure and heat into the desired shape of the bobbin.
