Description

Die Erfindung betrifft eine an einem SpuLenträger der AbLenksysteme für Fernsehbildröhren befestigte, mit metalLischen AnschLußstücken versehene Anschlußleiste.The invention relates to a terminal block attached to a bobbin of the deflection systems for television picture tubes and provided with metallic connecting pieces.

Derartige Anordnungen zum Kontaktieren der AbLenkspuLen von AbLenksystemen für Fernsehbildröhren sind bekannt. Bei den bekannten Anordnungen ist die Anschlußleiste als separates stegförmiges KunststoffteiL ausgebildet, in welches U-förmige Drahtklammern eingespritzt sind. Jede AnschLußLeiste besitzt zwei öffnungen, mit denen sie auf zwei, am SpuLenträger angespritzte, mit Widerhaken versehene federnde Stücke aufgeschoben und dort eingerastet ist.Such arrangements for contacting the deflection coils of deflection systems for television picture tubes are known. In the known arrangements, the terminal block is designed as a separate web-shaped plastic part, into which U-shaped wire clips are injected. Each connector strip has two openings, with which it is pushed onto two resilient pieces that are molded onto the spool holder and barbed and snapped into place.

Diese bekannte Anordnung zum Kontaktieren der AblenkspuLen von AbLenksystemen hat sich an sich bewährt. Es besteht jedoch der Wunsch, die AnzahL der Kontaktstücke an der Anschlußleiste zu erhöhen und sie derart auszugestalten, daß die Kontaktstücke nicht nur für eine Lötverbindung, sondern auch für den Anschluß von Steckern geeignet sind. Dafür ist die bekannte Anordnung wegen der nicht ausreichenden StabiLität der Kontaktstifte und der Anschlußleiste nicht geeignet.This known arrangement for contacting the deflection coils of deflection systems has proven itself. However, there is a desire to increase the number of contact pieces on the terminal block and to design them in such a way that the contact pieces are not only for a solder joint tion, but are also suitable for connecting plugs. The known arrangement is not suitable for this because of the insufficient stability of the contact pins and the terminal block.

Die der Erfindung zugrunde Liegende Aufgabe besteht darin, die Anschlußleiste an einem SpuLenträger von AbLenksystemen für FernsehbiLdröhren derart zu gestalten, daß neben einer kostengünstigeren HersteLLungsweise auch eine QuaLitätsverbesserung im vorstehend erwähnten Sinne erreicht wird.The object on which the invention is based is to design the connecting strip on a spool holder of deflection systems for television picture tubes in such a way that, in addition to a more cost-effective method of production, an improvement in quality in the sense mentioned above is achieved.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Anschlußleiste als einstückig mit dem SpuLenträger gespritzte Leiste ausgebildet ist, an der die AnschLußstükke befestigt sind.This object is achieved in that the terminal block is designed as a one-piece molded with the SpuLträger, to which the connecting pieces are attached.

In den Ansprüchen 2 bis 4 ist angegeben, in welcher Weise die Anschlußstücke günstig ausgebildet und an der AnschLußLeiste befestigt sein sollen: Die Erfindung ist nachstehend anhand der Figuren 1 bis 4 erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf die Rückseite des SpuLenträgers,
  • Fig. 2 die Seitenansicht des SpuLenträgers gemäß Fig. 1,
  • Fig. 3 eine Ausführungsform der Kontaktstücke,
  • Fig. 4 eine andere Ausführungsform der Kontaktstücke und
  • Fig. 5 eine weitere Ausführungsform der Kontaktstücke.
Claims 2 to 4 state how the connecting pieces should be designed to be cheap and fastened to the connecting strip: the invention is explained below with reference to FIGS. 1 to 4. Show it:
  • 1 is a plan view of the back of the spool holder,
  • 2 shows the side view of the bobbin holder according to FIG. 1,
  • 3 shows an embodiment of the contact pieces,
  • Fig. 4 shows another embodiment of the contact pieces and
  • Fig. 5 shows another embodiment of the contact pieces.

Fig. 1 zeigt die Rückseite des SpuLenträgers 1. Die Rückseite des SpuLenträgers ist bei eingebautem Ablenksystem zu erkennen, wenn man die Rückseite der FernsehbiLdröhre betrachtet. Dann befindet sich der RöhrenhaLs der Fernsehbitdröhre in der öffnung 2 des SpuLenträgers und der SpuLenträger mit dem AbLenksystem sind auf dem Röhrenhals festgeklemmt. Fig. 2 zeigt den Spulenträger gemäß Fig. 1 in Seitenansicht.Fig. 1 shows the back of the spool holder 1. The back of the spool holder can be seen with a built-in deflection system when one looks at the back of the television picture tube. Then the tube holder of the television bit tube is in the opening 2 of the coil holder and the coil holder with the deflection system are clamped onto the tube neck. FIG. 2 shows the coil carrier according to FIG. 1 in a side view.

Wie Fig. 1 und 2 verdeutlichen, sind die Anschlußleisten 3 - ohne AnschLußstücke - einstückig gemeinsam mit dem aus Kunststoff bestehenden SpuLenträger 1 gespritzt. Bei der aus Fig. 1 ersichtlichen Ausführungsform der AnschlußLeiste 3 besitzt diese Führungsnuten 4. Wie aus Fig. 3 deutlich wird, ist eine solche AusgestaLtung der AnschLußLeiste 3 dann zweckmäßig, wenn AnschLußstücke 5 verwendet werden, die U-förmig gestaltet sind und am Boden eine maulförmige öffnung besitzen. Derart gestaltete AnschLußstücke 5 können in einfacher Weise maschineLL in die Führungsnuten 4 der Anschlußleiste 3 eingeschoben werden. Wenn der Steg 6 der mauLförmigen öffnung - wie in Fig. 3 gezeigt - mit einem widerhakenartigen Ende versehen ist, dann verhaken sich die aufgeschobenen AnschLußstücke 5.1 and 2 illustrate, the terminal strips 3 - without connecting pieces - are injection-molded in one piece together with the plastic bobbin holder 1. In the embodiment of the connecting bar 3 shown in FIG. 1, this has guide grooves 4. As is clear from FIG. 3, such a configuration of the connecting bar 3 is expedient when connecting pieces 5 are used which are U-shaped and have a bottom one have mouth-shaped opening. Connections 5 designed in this way can be inserted in a simple manner by machine into the guide grooves 4 of the connecting strip 3. If the web 6 of the wall-shaped opening - as shown in FIG. 3 - is provided with a barb-like end, then the pushed-on connection pieces 5 get caught.

Die Anschlußstücke 5 können aber auch in der aus Fig. 4 ersichtlichen Weise ausgestaltet sein. Ein solches Anschlußstück ist gLeichfaLLs U-förmig ausgebildet und an seinem Boden mit einer Lasche 7 versehen. Wenn das U-förmige Anschlußstück 5 mit einer Lasche 7 versehen ist, dann können die Anschlußstücke 5 mit der Lasche 7 in entsprechende öffnungen der Anschlußteiste eingesetzt und die auf der Rückseite der Anschlußleiste überstehenden TeiLe der Laschen verschränkt werden.The connectors 5 can also be designed in the manner shown in FIG. 4. Such a connector is also U-shaped and provided with a tab 7 on its bottom. If the U-shaped connecting piece 5 is provided with a tab 7, then the connecting pieces 5 with the tab 7 can be inserted into corresponding openings in the connecting strip and the protruding parts of the tabs on the back of the terminal block are interlaced.

Bei dem aus Fig. 5 ersichtlichen AusführungsbeispieL dagegen bestehen die Anschlußstücke 5 jedoch aus U-förmigen Stiften 8, welche in die AnschCußleiste 3 eingespritzt sind. Dies geschieht beispielsweise in der Weise, daß eine der AnzahL der Anschlußstücke entsprechende AnzahL von Drähten endlos in das Spritzwerkzeug eingeführt werden. Diese Drähte werden dann mit der AnschLußLeiste 3 umspritzt, auf Länge geschnitten und zur U-Form gebogen.5, however, the connecting pieces 5 consist of U-shaped pins 8, which are injected into the connecting strip 3. This is done, for example, in such a way that a number of wires corresponding to the number of connecting pieces is inserted endlessly into the injection mold. These wires are then extrusion-coated with the connecting strip 3, cut to length and bent into a U-shape.
