Description
Ablenkspuleneinheit mit Schutzhaube Die Erfindung bezieht sich auf Ablenkspuleneinheiten, bei denen die Ablenkspulen für zwei aufeinander senkrecht stehende Ablenkrichtungen eine Baueinheit bilden, die von einer topfförmigen Schutzhaube umgeben ist. Bei den heute üblichen Ablenkspuleneinheiten sind die Horizontalablenkspulen sattelförmig ausgebildet, d.h. die Spulenachse steht senkrecht zum Rohrenhals, die Längsleiter verlaufen in Richtung der Röhrenachse und die Spulenköpfe sind vom Röhrenhais abgebogen. Die Langsleiterbündel werden von einem Jochring aus ferromagnetischem Material, z.B. einem Ferrit, umschlossen, der zugleich Kern für toroidförmige oder ebenfalls sattelförmige Vertikalablenkspulen ist. Deflection coil unit with protective hood The invention relates to Deflection coil units in which the deflection coils for two are perpendicular to each other standing deflection directions form a unit, which is covered by a cup-shaped protective hood is surrounded. In the deflection coil units customary today, the horizontal deflection coils are Saddle-shaped, i.e. the coil axis is perpendicular to the pipe neck, the Longitudinal conductors run in the direction of the tube axis and the coil ends are from the tube shark turned. The long conductor bundles are made of a ferromagnetic yoke ring Material, e.g. a ferrite, which is also the core for toroidal or is also saddle-shaped vertical deflection coils.
Es ist bekannt, derartige Ablenkspulen durch Klemmung der Schutzhaube auf dem Röhrenhals zu befestigen. Bei einer bekannten Anordnung werden hierzu die Ablenkspulen im ruckwårtigen Teil zusammen mit der Schutzhaube vergossen. Bei der bekannten Ablenkspuleneinheit erwarmen sich die Teile jedoch beträchtlich, da die erzeugte Wärme nicht abfließen kann.It is known to use such deflection coils by clamping the protective hood to attach to the tube neck. In a known arrangement, the Deflection coils cast in the rear part together with the protective cover. In the known deflection coil unit, however, the parts heat up considerably because the generated heat cannot flow away.
Es ist auch bekannt (PS 1 233 067), bei einer Ablenkspuleneinheit mit einem Isoliertrichter zwischen Horizontal- und Vertikalablenkspulen und einer die Ablenkeinheit umgebenden Schutzhaube die Ab-.It is also known (PS 1 233 067) for a deflection coil unit with an insulating funnel between horizontal and vertical deflection coils and a the deflector surrounding the protective hood.
lenkeinheit mit der Schutzhaube durch Rastmittel an den Stirnseiten von Isoliertrichter und Schutzhaube zu verbinden. Diese Anordnung erfordert jedoch einen besonders geformten Isoliertrichter und einen relativ großen Umfang der Schutzhaube.Steering unit with the protective hood by means of locking means on the front sides to be connected by insulating funnel and protective hood. However, this arrangement requires a specially shaped insulating funnel and a relatively large circumference of the protective hood.
Der Erfindung liegt die Aufgabe zugrunde, bei guter Wärmeableitung die Abmessungen zu verringern und einen besonders geformten Isoliertrichter zu vermeiden. Die Erfindung besteht darin, daß zur Verbindung der Ablenkeinheit mit der Schutzhaube an der Schutzhaube Rastmittel vorgesehen sind, die an den Ablenkspulen einrasten.The invention is based on the object with good heat dissipation to reduce the dimensions and avoid a specially shaped insulating funnel. The invention consists in that for connecting the deflection unit to the protective hood latching means are provided on the protective hood which latch onto the deflection coils.
Die Erfindung wird im folgenden anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert.The invention is illustrated below with reference to two in the drawing Embodiments explained in more detail.
Fig. 1 zeigt eine Rastung an den vorderen Spulenköpfen, Fig. 2 eine Rastung an den hinteren Spulenköpfen.Fig. 1 shows a detent on the front coil heads, Fig. 2 shows a Latch on the rear coil heads.
In Fig. 1 ist ein senkrechter Schnitt durch eine Ablenkspuleneinheit dargestellt, bei der aus Vereinfachungsgründen nur eine der Spulen sichtbar ist. In einer topfförmigen Schutzhaube 1 ist die sattelförmige Zeilenablenkspule 2 so angeordnet, daß sich der rückwärtige Kopf 3 gegen den Boden 4 der Schutzhaube 1 abstutzt und der vordere Kopf 5 hinter Vorsprüngen 6 an der Schütz' haube einrastet.In Fig. 1 is a vertical section through a deflection coil unit shown in which, for the sake of simplicity, only one of the coils is visible. In a cup-shaped protective hood 1, the saddle-shaped line deflection coil 2 is like this arranged that the rear head 3 is against the bottom 4 of the protective hood 1 and the front head 5 snaps into place behind projections 6 on the contactor's hood.
Ein Kern 7 aüs ferromághetischem Máteriai, set. Ferrit umschließt zwei sattelf8rmige, einander gegenUberliegende Ablenkspulen 2.A core 7 of ferromagetic materials, set. Ferrite encloses two saddle-shaped, opposing deflection coils 2.
Ein Xsoliertrichter (nicht dargestellt) kann zwischen den Ablenkspulen verschiedener Ablenkrichtungen angeordnet sein. Die Schutzhaube 9 ist mit einem Ansatz 8 versehen, auf dem ggf. noch Zentriermagnete sowie eine Schelle 9 zur Befestigung der Ablenkeinheit auf dem Hals 10 einer Bildröhre angeordnet sind.An insulating funnel (not shown) can be placed between the deflection coils be arranged in different directions of deflection. The protective hood 9 is with a Approach 8 provided, on which, if necessary, centering magnets and a clamp 9 for attachment of the deflection unit are arranged on the neck 10 of a picture tube.
In Fig. 2 sind an der Innenseite des Schutzhaubenbodens 4 VorsprUnge 12 angebracht, die von hinten in die ruckwärtigen Spulenköpfe 3 einrasten.In Fig. 2 there are 4 projections on the inside of the protective hood base 12 attached, which snap into the rear coil heads 3 from behind.
