Description

Hochspannungstransformator für Fernsehgeräte, bestehend aus wenigstens einer Primär- und wenigstens einer Sekundärwicklung, welche in einem Isolierstoffgehäuse angeordnet sind, und wenigstens einem mit einem Anschluß der Sekundärwicklung in elektrischen Kontakt stehenden Anschlußkabel.High-voltage transformer for television sets, consisting of at least one primary and at least one secondary winding, which are arranged in an insulating material housing, and at least one connecting cable which is in electrical contact with a connection of the secondary winding.

Ein solcher Hochspannungstransformator ist bekannt (EP-B-66804). Bei dem bekannten Hochspannungstransformator sind die mit den entsprechenden Anschlüssen der Sekundärwicklung elektrisch leitend verbundenen Kabelenden, beispielsweise das Hochspannungskabel und das Kabel für die Fokussierspannung, fest mit diesen Anschlüssen verbunden, beispielsweise verlötet.Such a high-voltage transformer is known (EP-B-66804). In the known high-voltage transformer, the cable ends, for example the high-voltage cable and the cable for the focusing voltage, which are electrically conductively connected to the corresponding connections of the secondary winding are firmly connected, for example soldered, to these connections.

Das ist aus fertigungstechnischen Gründen vielfach unerwünscht. Bei der Fabrikation von Fernsehgeräten werden neuerdings, teilweise sogar auf weitgehend automatisch arbeitenden Fertigungsstraßen, den gleichen Aufbau aufweisende Fernsehgerätechassis für mit verschiedenen Bildröhren ausgerüstete Fernsehgeräte hergestellt. Auf diesen Fernsehgerätechassis sind auch bereits die Hochspannungstransformatoren montiert. Da diese Fernsehgerätechassis verschiedene Fertigungsstufen durchlaufen, beispielsweise auch über ein Lötbad geführt werden, sind mit dem Hochspannungstransformator fest verbundene Kabel unerwünscht, weil sie Störungen bei der Fertigung der Fernsehgerätechassis verursachen können.This is often undesirable for manufacturing reasons. In the manufacture of television sets, television set chassis having the same structure for television sets equipped with different picture tubes have recently been produced, in some cases even on largely automatic production lines. The high-voltage transformers are already mounted on this television chassis. Since these television set chassis go through different production stages, for example, also run over a solder bath, cables connected to the high-voltage transformer are undesirable because they can cause disruptions in the manufacture of the television set chassis.

Außerdem stellt sich mitunter erst bei der Montage der Fernsehgeräte heraus, welches Kabel für die Verbindung des auf dem Fernsehgerätechassis angeordneten Hochspannungstransformators mit der Bildröhre benötigt wird. In einem solchen Fall ist eine einfache Montage dieser Verbindungen erwünscht.In addition, it sometimes only becomes apparent when the television sets are being assembled which cable is required for connecting the high-voltage transformer arranged on the television set chassis to the picture tube. In such a case, simple assembly of these connections is desirable.

Eine Anordnung, bei welcher der Hochspannungsanschluß steckbar ist, ist aus EP-A-0 236 642 bekannt. Dazu ist am Isolierstoffgehäuse des Transformators eine rohrförmige Verlängerung ausgebildet, deren Baulänge, die die zur Hochspannungsfestigkeit erforderliche Isolationslänge allein herstellt. Auf das Anschlußkabel ist eine geschlitzte Hülse aufgesteckt. Zur Herstellung der Verbindung wird die Hülse in die Verlängerung eingeschoben. Dabei wird Innenwandung der Hülse gegen das Anschlußkabel gedrückt. Sobald die Hülse ihre Endlage in der Verlängerung eingenommen hat, wird ein am Außenmantel der Hülse angeformter Kragen von einem Schnapphaken umgriffen, der auf dem oberen Rand der Verlängerung angeordnet ist.An arrangement in which the high-voltage connection can be plugged in is known from EP-A-0 236 642. For this purpose, a tubular extension is formed on the insulating housing of the transformer, the overall length of which alone produces the insulation length required for high-voltage strength. A slotted sleeve is attached to the connection cable. To make the connection, the sleeve is inserted into the extension. The inner wall of the sleeve is pressed against the connection cable. As soon as the sleeve has reached its end position in the extension, a collar which is formed on the outer jacket of the sleeve is gripped by a snap hook which is arranged on the upper edge of the extension.

Der Erfindung liegt daher das technische Problem Zugrunde, einen Hochspannungstransformator für Fernsehgeräte zu schaffen, an dem die Anschlußkabel für die hohen Gleichspannungen lösbar, aber dennoch zugfest befestigt sind, bei dem eine gute Kontaktgabe mit den Anschlüssen im Inneren des Hochspannungstransformators gewährleistet ist und der eine möglichst geringe Bauhöhe aufweist.The invention is therefore based on the technical problem of creating a high-voltage transformer for televisions on which the connecting cables for the high direct voltages are detachable, but are nevertheless fastened in a tensile manner, in which good contact with the connections inside the high-voltage transformer is ensured and the one possible has low overall height.

Dieses technische Probelm ist erfindungsgemäß dadurch gelöst, daß das Isolierstoffgehäuse eine einstückig angeformte rohrförmige Verlängerung mit einer einstückig angeformten Öse besitzt, daß eine auf die Verlängerung aufsteckbare, an ihrem unteren Ende mit einem einstückig angeformten federnden, mit der Öse zusammenwirkenden Haken versehene Hülse vorgesehen ist, an der einstückig eine in den für die Aufnahme des Hochspannungskabels vorgesehenen Raum der Verlängerung eintauchende Lasche angeformt ist.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 4 enthalten. Sie ist nachstehend anhand der Figuren 1 und 2 näher erläutert. Es zeigen:

Fig.1
den Längsschnitt durch den Teil eines Hochspannungstransformators mit den erfindungsgemäßen Merkmalen und
Fig.2
die Draufsicht auf einen Schnitt entlang der Linie AB gemäß Fig.1.
This technical problem is solved according to the invention in that the insulating housing has an integrally molded tubular extension with an integrally molded eyelet, that one can be plugged onto the extension, with one piece at its lower end molded resilient, provided with the eye cooperating hook sleeve is provided on which is integrally formed a plunger into the space provided for receiving the high-voltage cable extension.
Advantageous embodiments of the invention are contained in claims 2 to 4. It is explained in more detail below with reference to FIGS. 1 and 2. Show it:
Fig. 1
the longitudinal section through the part of a high voltage transformer with the features of the invention and
Fig. 2
the top view of a section along the line AB of Figure 1.

Wie aus Fig.1 zu erkennen, sind in dem Isolierstoffgehäuse 1 die Primärwicklung 2 und die Sekundärwicklungen des Hcohspannungstransformators angeordnet. Die Sekundärwicklungen sind in Kammern des Spulenkörpers 3 untergebracht, und zwischen den in den Kammern untergebrachten Sekundärwicklungen sind Dioden 4 angeordnet. Daran ist zu erkennen, daß es sich bei den gezeigten Ausführungsbeispiel um einen Diodensplit - Hochspannungstransformator handelt. Bei dem Anschlußstift 5 handelt es sich um den Hochspannunganschluß. Die Spitze des Anschlußstiftes 5 endet in einem Pfropfen 6 aus Leitgummi, welcher an der tiefsten Stelle der rohrförmigen Verlängerung 7 angeordnet ist. In den Pfropfen 6 taucht auch die Seele 8 des Hochspannungskabels 9 ein.As can be seen from FIG. 1, the primary winding 2 and the secondary windings of the high-voltage transformer are arranged in the insulating housing 1. The secondary windings are accommodated in chambers of the coil former 3, and diodes 4 are arranged between the secondary windings accommodated in the chambers. This shows that the exemplary embodiment shown is a diode split high-voltage transformer. The pin 5 is the high voltage connection. The tip of the connecting pin 5 ends in a plug 6 made of conductive rubber, which is arranged at the lowest point of the tubular extension 7. The core 8 of the high-voltage cable 9 is also immersed in the plug 6.

Es ist ein weiteres Anschlußkabel 10 zum Hochspannungstransformator geführt und in der Vertiefung 20 des Isolierstoffgehäuses 1 angeordnet; bei diesem Anschlußkabel kann es sich beispielsweise um das Kabel handeln, mit dem die Fokussierungsspannung vom Hochspannungstransformator zum Fernsehgerätechassis geführt wird. Auch bei dieser Anordnung ist die elektrisch leitende Verbindung dadurch hergestellt, daß der entsprechende Abgriff an der Sekundärabwicklung mit dem Anschlußstift 11 in den Pfropfen 12 aus Leitgummi geführt ist, in welchen auch die Seele 13 des Anschlußkabels 10 eintaucht.There is a further connection cable 10 to the high-voltage transformer and arranged in the recess 20 of the insulating housing 1; this connection cable can be, for example, the cable with which the focusing voltage is led from the high-voltage transformer to the television chassis. In this arrangement, too, the electrically conductive connection is established in that the corresponding tap on the secondary processing is guided with the connecting pin 11 in the plug 12 made of conductive rubber, in which the core 13 of the connecting cable 10 is also immersed.

Die Verlängerung 7 des Isolierstoffgehäuses 1 weist - wenigstens im oberen Teil - einen von oben nach unten abnehmenden Innendurchmesser auf. Im unteren Teil des Inneren der Verlängerung 7, nicht weit von der Oberfläche des Pfropfens 6 entfernt, ist an der Innenwand der Verlängerung 7 eine radial nach innen gerichtete Klemmnase 14 einstückig angeformt. Da es sich bei diesen Bauteilen des Hochspannungstransformators in der Regel um Kunststoffspritzteile handeln wird, sind die einstückig angeformten Teile bereits bei der Herstellung der Kunststoffspritzteile mit hergestellt worden. Auf der Außenseite der Verlängerung 7 ist auch die Öse 15 einstückig angeformt worden.The extension 7 of the insulating material housing 1 has - at least in the upper part - an inside diameter that decreases from top to bottom. In the lower part of the interior of the extension 7, not far from the surface of the plug 6, a radially inwardly directed clamping lug 14 is integrally formed on the inner wall of the extension 7. Since these components of the high-voltage transformer will generally be plastic injection-molded parts, the integrally molded parts have already been produced during the production of the plastic injection-molded parts. On the outside of the extension 7, the eyelet 15 has also been integrally formed.

Bei der aus Fig.1 ersichtlichen Darstellung, bei welcher das Hochspannungskabel 9 und das Anschlußkabel 10 bereits fest montiert sind, ist erkennbar, daß die Hülse 16 über die Verlängerung 7 geschoben worden ist.1, in which the high-voltage cable 9 and the connecting cable 10 are already firmly mounted, it can be seen that the sleeve 16 has been pushed over the extension 7.

Die Hülse 16 besitzt eine sich in den Innenraum der Verlängerung 7 erstreckende Lasche 17. Am unteren Ende der Hülse 16 ist der Haken 18 einstückig angeformt, welcher hinter der Öse 15 einrastet. Außerdem ist die Hülse 16 mit der einstückig angeformten Klammer 19 versehen.The sleeve 16 has a tab 17 extending into the interior of the extension 7. The hook 18 is integrally formed on the lower end of the sleeve 16 and engages behind the eyelet 15. In addition, the sleeve 16 is provided with the integrally molded bracket 19.

Die Montage des Hochspannungskabels 9 erfolgt in folgender Weise:
Nachdem die Hülse 16 auf das Ende des Hochspannungskabels 9, an dem die Seele 8 freigelegt worden ist, aufgesteckt worden ist, wird dieses Ende des Hochspannungskabel bis zum Pfropfen 6 in die Verlängerung 7 eingeschoben. Anschließend wird die Hülse 16 auf die Verlängerung 7 aufgeschoben. Dabei schiebt sich die Lasche 17 zwischen die Innenfläche der Verlängerung 7 und die Oberfläche des Hochspannungskabels 9. Dadurch wird das Ende des Hochspannungskabels 9 einerseits in der Verlängerung 7 festgeklemmt und andererseits dringt die Klemmnase 14 in die Isolation des Hochspannungskabels 9 ein. Das erzeugt eine formschlüssige Befestigung des Hochspannungskabels. Die Lage der Hülse 16 ist dadurch gesichert, daß der Haken 18 hinter der Öse 15 eingerastet ist.The high-voltage cable 9 is installed in the following way:
After the sleeve 16 has been plugged onto the end of the high-voltage cable 9, on which the core 8 has been exposed, this end of the high-voltage cable is pushed into the extension 7 up to the plug 6. Then the sleeve 16 is pushed onto the extension 7. The tab 17 is pushed between the inner surface of the extension 7 and the surface of the high-voltage cable 9. As a result, the end of the high-voltage cable 9 is clamped on the one hand in the extension 7 and, on the other hand, the clamping lug 14 penetrates into the insulation of the high-voltage cable 9. This creates a form-fitting attachment of the high-voltage cable. The position of the sleeve 16 is secured in that the hook 18 is locked behind the eyelet 15.

Die Kontaktgabe erfolgt beim Anschlußkabel 10 in der Vertiefung 20 mit den gleichen Mitteln wie beim Hochspannungskabel 9. Die Zugentlastung des Anschlußkabels 10 erfolgt dadurch, daß es an der Klammer 19 festgeklemmt ist.The contact is made with the connecting cable 10 in the recess 20 with the same means as with the high-voltage cable 9. The strain relief of the connecting cable 10 takes place in that it is clamped on the clamp 19.

Die Ausgestaltung der Klammer 19, der Lasche 17 und der Öse 15 ist aus Fig.2 deutlich zu erkennen.The design of the bracket 19, the tab 17 and the eyelet 15 can be clearly seen from Fig.2.

Die erfindungsgemäße Lösung bringt eine Verbesserung in mehrfacher Hinsicht. Sie vereinfacht die Montage der Anschlußkabel. Das Hineinschieben der Kabelenden an den vorgesehenen Ort ist ohne Behinderung möglich. Für die Befestigung von zwei oder mehr Kabeln ist nur ein Bauteil erforderlich. Bei dem neuen Hochspannungstransformator können die erforderlichen Sicherheitswerte auch bei einer geringeren Bauhöhe eingehalten werden.The solution according to the invention brings an improvement in several respects. It simplifies the assembly of the connection cables. Pushing the cable ends into the intended location is possible without hindrance. Only one component is required to attach two or more cables. With the new high-voltage transformer, the required safety values can be maintained even with a lower overall height.

Die erforderliche Isolationslänge beim Hochspannungsanschluß des neuen Hochspannungstransformators wird durch die Länge der Hülse 16 eingestellt. Da die Hülse 16 aber erst bei der Endmontage des Fernsehgerätes montiert wird, weist der neue Hochspannungstransformator bei der Herstellung des Fernsehgerätechassis eine geringere Bauhöhe als im Endzustand auf, wodurch die Handhabung des Fernsehgerätechassis erleichtert wird.The length of insulation required for the high-voltage connection of the new high-voltage transformer is set by the length of the sleeve 16. However, since the sleeve 16 is only assembled during the final assembly of the television set, the new high-voltage transformer has a lower overall height in the manufacture of the television set chassis than in the final state, which makes handling the television chassis easier.
