Description
Einlagige Spule ohne Spulenkörper mit veränderbarer Selbstinduktion Die Erfindung betrifft eine einlagige, zylindrische Spule, vorzugsweise aus Kupferlackdraht, bei der die Windungen dicht gewickelt sind, Zusätzlich zum isolierenden LackUberzüg trägt der Kupferdraht aussen noch eine Auflage, mit deren Hilfe die einzelnen Windungen nach dem Wickeln miteinander verbunden werden. Single-layer coil without bobbin with changeable self-induction The invention relates to a single-layer, cylindrical coil, preferably made of enamelled copper wire, in which the turns are tightly wound, in addition to the insulating varnish coating the copper wire has a support on the outside, with the help of which the individual turns be connected to each other after winding.
Die Auflage kann z.B. aus einem thermoplastischen Material bestehen, das nach dem Wickeln mittels eines Wärmeschocks zum Erweichen gebracht wird und dann anschliessend bei Erkalten die gesamte Spule von Windung,zu Windung zu einem einheitlichen Ganzen verbäckt.The support can for example consist of a thermoplastic material, which is softened after swaddling by means of a thermal shock and then afterwards when cooling down the entire coil from turn to turn to one baked into a uniform whole.
Das Verbacken der Spule geschieht in bekannter Weise entweder durch eine von aussen auf die Spule einwirkende Wärmequelle oder durch einen entsprechend dimensionierten Stromstoss,der die Wicklung durchfliesst und diese erwärmt. Die dicht bei dicht liegenden Windungen der Wicklung bilden dann im Inneren der Spule ein gewinde, Der Drahtdurchmesser ist so bemessen, dass das durch das Wickeln entstehende Gewinde zu dem Aussengewinde des für die Spule vorgesehenen Abstimm-Mittels (Ferritkern, Altern oder dergl.) passtf Zum Ausgleich tfir mechanische Toleranzen und zur Bremsung des Eisenkernes beim Abgleichvorgang wird in bekannter Weise in das Gewinde ein elastisches Mittel, z.B. Gummi-Faden oder Streifen aus geschäumten Kunststoff eingelegt. Nach dem Verbacken ist die einlagige zylindrische Spule mit ihrer Abgleichmöglichkeit durch den einschraubbaren Eisenkern eine handliche Einheit, die mit ihren abisolierten Drahtenden unmittelbar in die Bohrungen von Leiterplatten eingesetzt werden und dort verlötet werden kann.The coil is baked in a known manner either by a heat source acting on the coil from outside or by a corresponding one dimensioned current impulse that flows through the winding and heats it up. the closely spaced turns of the winding then form inside the coil a thread, the wire diameter is dimensioned so that the resulting from the winding Thread to the external thread of the tuning means provided for the coil (ferrite core, Aging or the like) fits to compensate for mechanical tolerances and to brake of the iron core during the adjustment process is used in a known manner in the thread an elastic means, e.g. rubber thread or strips of foamed Plastic inserted. After baking, the single-layer cylindrical coil is included its adjustment possibility through the screw-in iron core a handy unit, those with their stripped wire ends directly into the holes in printed circuit boards can be used and soldered there.
Das Verkleben der Windungen untereinander kann auch dadurch bewirkt werden, dass der zum Wickeln der Spule benutzte Kupferlackdraht zusätzlich mit einer Umspinnung aus Acetatseide versehen wird. Nach dem Wickeln wird die Spule einem AcetatHNebel ausgesetzt, dessen Tröpfchen die Umspinnung aus Acetatseide anlösen und dadurch eine Verklebung der Windungen untereinander bewirken.This can also cause the turns to stick to one another that the enamelled copper wire used to wind the coil is additionally covered with a Wrapping made of acetate silk is provided. After winding, the coil becomes a Exposure to acetate mist, the droplets of which dissolve the acetate silk covering and thereby cause the turns to stick together.
Einlagige zylinderförmige Spulen werden im allgemeinen in Hochfrequenzstronikreisen verwendet, deren Frequenzen meist im Kurzwellen- und Ultraschallwellen-Bereich liegen. In vielen Anwendungsfällen kommt es dabei gar nicht auf eine besondere Spulengüte an, da insbesondere bei Breitbandverstärkern, z,B. bei Zwischenfrequenz-VerstArkern von Fernsehgeräten die Schwingkreise sowieso mit zusätzlichen Dämpfungsmitteln versehen sind. In &erstärkern dieser Art werden zum Halten der Spulen Spulenkörper, vorzugsweise aus Kunststoff verwendet, die im Inneren ein Innengewinde besitzen, in dem der zum Ab gleichen der Selbstinduktion der Spule erforderliche Abstimmkern geführt wird. Das Festlegen der Spule auf dem Spulenkörper und das Einsetzen und Befestigen des Spulenkörpers auf der Leiterplatte sind Arbeiten, die besonders in einer Mengenfertigung Zeit und Geld kosten. Man hat aus diesem Grunde auch schon Spulen gar nicht mehr aus Draht gewickelt, sondern aus dem Leitermaterial der Leiterplatte selbst durch Druck- und Aetz-Vorgänge hergestellt. Aber auch diese Spulen müssen abgiiichbar gemacht werden, wozu wieder Abstimmkerne benötigt werden, die zu ihrer Halterung und Führung wiederum-unbewickelte Spulenkörper benötigen, so dass durch das Drucken der Spulen im wesentlichen nur der Wickelvorgang,- nicht aber der Spulenkörper und seine Befestigung in der Leiterplatte gespart wird.Single layer cylindrical coils are commonly used in high frequency electronics travel used, the frequencies of which are mostly in the shortwave and ultrasonic wave range. In many applications there is no particular quality of the coil because, especially in the case of broadband amplifiers, e.g. with intermediate frequency amplifiers of television sets provided the oscillating circuits with additional damping means anyway are. In & strengtheners of this type, coil formers are preferably used to hold the coils made of plastic, which have an internal thread in which the for From the same the self-induction of the coil required tuning core is performed. Setting the coil on the Bobbin and inserting and Fastening the bobbin to the circuit board are jobs that are especially important in volume production costs time and money. For this reason one already has Coils are no longer wound from wire, but from the conductor material of the circuit board produced by pressure and etching processes. But these coils also have to are made calibratable, for which purpose tuning cores are required that are part of their Bracket and guide, in turn, require unwound bobbins so that through the printing of the bobbins is essentially only the winding process, but not the bobbin and its fixing in the circuit board is saved.
Bei einer Spule gemäss vorliegender Erfindung wird der Spulenkörper ganz eingespart und zur Kernführung wird das im Inneren der Spule durch den Wickelvorgang entstandene Gewinde benutzt.In the case of a coil according to the present invention, the coil body is This is completely saved and the core is guided by the winding process inside the bobbin resulting threads are used.
Nähere Einzelheiten sind aus dem im folgenden beschriebenen Ausfuhrungsbeispiel zu ersehen.Further details are from the exemplary embodiment described below to see.
Fig. 1 zeigt eine Spule gemäss vorliegender Erfindung in liegender und Figur 2 in stehender Bauart. Die aus isoliertem Kupferdraht bestehende Wicklung (1) ist nach dem Wickeln und Abbiegen und Abisolieren der Enden auf einem Automaten durch einen Stromstoss, der die auf dem Draht befindliche thermoplastische Auflage infolge des durch den Stromstoss ausgelösten Wärmeschocke zum Schmelzen und anschliessenden Zusammenfliessen und Verbacken gebracht hat, zu einer leicht handhabbaren Einheit verbacken worden, die mit ihren abisolierten Drahtenden (2) in Löcher der Leiterplatte (3) eingesetzt wird und mit der Kaschierung (4) der Leiterplatte verlötet wird.Fig. 1 shows a coil according to the present invention in a horizontal position and FIG. 2 in a standing design. The winding made of insulated copper wire (1) is after winding and bending and stripping the ends on a machine by a current surge that affects the thermoplastic overlay on the wire as a result of the thermal shock triggered by the current surge to melting and subsequent Has brought together and caked, an easy to use one Unit have been baked with their stripped wire ends (2) in holes in the Circuit board (3) is inserted and soldered to the lamination (4) of the circuit board will.
Zweckmässigerweise schon vor dem Einsetzen der Spule in die Leiterplatte wird der Eisenkern (5) unter Zwischenlegen einer Kernbremse (6) aus einem elastischen Material in die Spule eingeschraubt und gegebenenfalls schon vorabgeglichen.It is advisable to do this before inserting the coil into the circuit board the iron core (5) is made of an elastic one with the interposition of a core brake (6) Material screwed into the coil and, if necessary, already adjusted.
