Description

Gegenstand der vorliegenden Erfindung ist eine Bandfilterhefestigung für Rundfunk-Ernpfangsrerätc.The present invention relates to a belt filter attachment for radio reception devices c.

Die bisher bekanntgewordenen Ausführungen kennzeichnen sich wie folgt: i. Die Bandfilterplatte wurde nur am Abschirmbecher durch geeignete I1)efestigungsmittel gehalten, und der komplette .\b>schirnibecher mit Bandfilterplatte mußte mittels Schrauben oder angenieteter Laschen am Chassis des Gerätes befestigt werden; 2. die Bandfilterplatte wurde von unten in ein Chassisloch eingeschoben und der Abschirmbecher nach dem Überschieben a rn Chassis angeschraubt. Durch Nuten des Chassisloches wurde die Bandfilterplatte geführt und an der Oberseite des Bechers befestigt. Bei dieser :\usführung wurden beim Einschieben der Haridfilterplatte die Spulen durch die sehr scharfen kanten des Chassisloches sehr leicht beschädigt.The versions that have become known so far are characterized as follows: i. The band filter plate was only fastened to the shielding cup by means of suitable I1) fasteners held, and the complete. \ b> Schirnibecher with band filter plate had to be by means of Screws or riveted lugs are attached to the chassis of the device; 2. the band filter plate was pushed into a chassis hole from below and the shielding cup screwed onto the chassis after sliding it over. By grooving the chassis hole the belt filter plate and attached to the top of the beaker. At this : \ execution when the Harid filter plate was pushed in, the coils through the very Sharp edges of the chassis hole damaged very easily.

Nach der Erfindung wird zur Erzielung einer vereinfachten und verbilligten Herstellungsweise ehre Befestigungsart der Bandfilterplatte mit Abschirmbecher am Chassis angegeben, die keinerlei Schraub>- oder Nietarbeiten erfordert und dadurch in vorteilhafter Weise ein müheloses Auf- und Absetzen des Bandfilterb echers ermöglicht. Danach wird die Bandfilterplatte stets von oben eingehakt, #O daß die sehr empfindlichen Bandfilterspuleri mit (lern Chassis nicht in Berührung kommen können tin(1 eine Beschädigung derselben unmöglich ist.According to the invention to achieve a simplified and cheaper Manufacturing method honors the method of fastening the band filter plate with shielding cup on the Chassis specified, which does not require any screwing or riveting work and therefore in an advantageous manner allows effortless putting on and taking off the band filter cup. Then the band filter plate is always hooked in from above, #O that the very sensitive ones Belt filter spools with (learn the chassis cannot come into contact with tin (1 a Damage to the same is impossible.

Erfindungsgemäß ist dieBandfilterplatte am utlteren Ende mit :\usklinkungen versehen, die nach l:infiillrttng der Bandfilterplatte von oben in ein Loch des Chassis in Einklinkungen oder Nuten an (len Lochrändern greifen, während das obere, abgesetzte Eride der Bandfilterplatte durch einen Schlitz des übergestülpten Abschirmbechers faßt und durch einen Keil mit demselben verbunden wird. Auf diese Weise ist ohne Niete oder Schrau-1>en eine feste Verbindung von Bandfilterplatte und .\l)scllirllllwcher mit der Grundplatte des Chassis hergestellt.According to the invention, the band filter plate is at the lower end with: \ unklinkungen provided, which after infiillrttng the belt filter plate from above into a hole in the The chassis in notches or grooves (grip the edges of the holes, while the upper, Stepped eride of the band filter plate through a slot in the shielding cup grips and is connected to the same by a wedge. This way is without Rivets or screws provide a firm connection between the band filter plate and the scllirllllwcher made with the base plate of the chassis.

_\tif der Zeichnung ist der Erfindungsgegenstand in einem .\tisfiilirtnigsbeispiel schematisch darge#tellt, und zwar zeigt Fig. i die Bandfilterplatte mit den Spulen und Kondensatoren sowie den dazugehörigen Abschirinbecher, Fig. 2 einen Ausschnitt aus (lern Chassis und Fig. 3 das zusammengesetzte Bandfilter auf dem Chassis._ \ tif the drawing is the subject matter of the invention in a. \ tisfiilirtnigsbeispiel schematically illustrated, namely Fig. 1 shows the band filter plate with the coils and capacitors and the associated shielding cup, FIG. 2 shows a detail from (learn chassis and Fig. 3 the assembled band filter on the chassis.

Gemäß der Erfindung besitzt die aus Hartpapier bestehende Bandfilterplatte i seitliche _\ussparungen oder Ausklinkungen i i. die so ausgebildet sind, daß nach Einführung der Baridfilterplatte i 111 ein Loch 12 des beispielsweise aus i mm Stahlblech gefertigten Chassis 7 und nach Verschieben der Platte i diese in Nuten 13 des Loches 12 eingehakt werden kann. Über die jetzt gegen Herausziehen gesicherte Bandfilterplatte i wird der Aluminiuinabschirmhecher 6 geschoben und durch die am Chassis 7 hochstehenden Nasen 8 zentriert. Das obere, abgesetzte Ende der Platte i schielt sich dabei ein Stück aus dein rechteckigen Schlitz io des Abschirmbechers hervor, so daß jetzt durch Einsetzen des Bandfilterkeiles o ein absolut fester Sitz von Bandfilterplatte i und .\bschirrnbecher 6 auf dem Chassis erreicht ist.According to the invention, the band filter plate made of hard paper has i lateral recesses or notches i i. which are designed so that after Introduction of the barid filter plate i 111 a hole 12 of, for example, i mm sheet steel manufactured chassis 7 and after moving the plate i this in grooves 13 of the hole 12 can be hooked. Via the belt filter plate, which is now secured against being pulled out i the aluminum shield 6 is pushed and through the upright on the chassis 7 Noses 8 centered. The upper, remote end of the plate i switched on Piece out of your rectangular slot io of the shielding cup, so that now by inserting the belt filter wedge o an absolutely tight fit of the belt filter plate i and. \ bschirrnbecher 6 is reached on the chassis.

Auf der Bandfilterplatte i sind in üblicher Weise die beiden SptOen 3, 5 und die Kondensatoren 2, .4 angebracht.The two SptOs are on the band filter plate i in the usual way 3, 5 and the capacitors 2, .4 attached.
