Description

Für transportable Geräte ist ein Aufbau der Empfänger zu schaffen, der eine einfache Anoridnung .der Abstimmung und gleichzeitig gute Abschnrmmöglichkeit der einzelnen Stufen gegeneinander zeigt.A receiver structure must be created for transportable devices, a simple arrangement. of the vote and at the same time good possibilities for adjustment of the individual stages shows against each other.

Es werden die verschiedenen Kreise induktiv abgestimmt, da dies den einfachsten Aufbau ergibt. .Die Mittelachse aller Spulen bildet eine Gerade, so daß ein freier Durchgang durch alle Spulen für die Abstimmkerne gegeben ist. Diese bekannte Anordnung ist für hohe Frequenzen nur anwendbar, wenn besondere Abschirmm:aßnahrnen getroffen werden. Die Erfindung betrifft nun eine Abschirmung, die eine einwandfreie Trennung der Kreise gewährleistet, ohne die Dämpfung merklich zu erhöhen.The different circles are inductively tuned, as this is the simplest structure results. The center axis of all coils forms a straight line, see above that there is free passage through all coils for the tuning cores. These known arrangement is only applicable for high frequencies if special shielding: aßnahrnen to be hit. The invention now relates to a shield that is flawless Separation of the circles ensured without noticeably increasing the attenuation.

Die einzelnen Stufen sind durch Zwischenwände, die die Spulenkörper tragen, voneinander abgeschirmt, wobei -die Spulen durch in den Zwischenwänden sitzende geschlitzte Rohrstücke entkoppelt «-erden. Diese Rohrstücke dienen bei Verwendung von Einzelspulen gleichzeitig als Träger für die Spulenkö-rper. Wie aus .der Abbildung ersichtlich ist, besteht,dann die gesamte Anordnung aus einem Winkel, auf dem die Zwischenwände sitzen, wobei die Zwischenwand unten in einem rohrartigen Gebilde endet, in dem die Röhre jeder Stufe untergebracht ist. Dieser Metallaufbau wird dann entweder aus Blech oder Spritzguß hergestellt.The individual stages are through partition walls that hold the coil formers wear, shielded from each other, with -the coils by sitting in the partition walls slotted pipe sections decoupled «-earth. These pipe pieces are used when in use of individual coils at the same time as a carrier for the coil formers. As shown in the illustration can be seen, then the entire arrangement consists of an angle on which the Partition walls sit, with the partition wall below in a tubular structure ends, in which the tube of each stage is housed. This metal structure will then made either from sheet metal or injection molding.
