Miniatur-Hochfrequenzspule mit KondensatorMiniature high frequency coil with capacitor
Für sehr eng aufgebaute Hochfrequenzempfängerschaltungen ist es insbesondere bei den höheren Zwischenfrequenzen (z.B. FM—Zwischenfrequenz 10,7 MHz) unabdingbar, den Kondensator im Innern des Äbschinnbechers unterzubringen, der die Spule umschließt, weil sonst die relativ hohen Resonanzströme in umliegende Bauelemente Störungen induzieren.For high-frequency receiver circuits built very closely together, it is Especially with the higher intermediate frequencies (e.g. FM intermediate frequency 10.7 MHz), the capacitor inside the To accommodate Äbschinnbechers that surrounds the coil because otherwise the relatively high resonance currents in the surrounding components Induce disturbances.
Die fertigungstechnische Montage des Kondensators innerhalb des Aufbaues macht jedoch derartige Schwierigkeiten, daß eine rationelle und damit billige Herstellung nicht möglich ist. Wenn außerdem die Verwendung von keramischen Plättchenkondensatoren notwendig ist;, wirkt der etwa gleichgroße Durchmesser von Kondensatoranschlußdraht und Spulendrahtanschlußstift in verstärktem Maße hindernd.However, the technical assembly of the capacitor within the structure makes such difficulties that an efficient and thus cheap production is not possible. If besides the use of ceramic plate capacitors is necessary; the approximately equal diameter of the capacitor connecting wire acts and the coil wire terminal pin to an increased extent.
Die Neuerung umgeht diese Schwieriakeiten-dadurch, daß der Kon- The innovation bypasses these difficulties - in that the con -
densator die elektrische Verbindung mit der Spule erst beim Einsetzen in die gedruckte Schaltung bekommt, so daß keinerlei Montagearbeiten im Aufbau notwendig sind.capacitor only gets the electrical connection with the coil when it is inserted into the printed circuit, so that no Assembly work in the construction is necessary.
Die beiliegende Zeichnung zeigt in drei Ansichten, zum Teil geschnitten, den neuerungsgemäßen Aufbau.The accompanying drawing shows in three views, partially cut, the modern structure.
Hierbei ist (1) der Spulenkörper, der einstückig mit dem Spulenkörperfuß (5) hergestellt ist und der die Wicklung (10) oder die Wicklungen (10) trägt, deren Drahtenden um die Anschlußstifte (7) gelegt und mit diesen verlötet sind. (2) ist der Abschirmbecher, der mit angeschnittenen Lötfahnen (9) versehen ist. Der Zentralabgleichkern (3) bildet mit dem Feldrückführungskern (4) den magnetischen Weg der Spule. (6) ist die vorzugsweise als keramischer Flachkondensator ausgebildete Schwingkreiskapazität. Die Anschlußdrähte (8) ragen frei nach unten aus dem Spulenaufbau heraus und werden erst durch das Verlöten auf der gedruckten Schaltung elektrisch mit der Spule verbunden.Here (1) is the bobbin that is integral with the bobbin base (5) is made and which carries the winding (10) or the windings (10), the wire ends of which around the connecting pins (7) are placed and soldered to these. (2) is the shielding cup, which is provided with cut soldering lugs (9). The central adjustment kernel (3) forms the magnetic path of the coil with the field feedback core (4). (6) which is preferably more than ceramic Flat capacitor designed resonant circuit capacitance. The connecting wires (8) protrude freely downwards from the coil structure and are only electrically connected to the coil by soldering on the printed circuit.
