Description
Für die Herstellung von Induktionsspulen, besonders für niedrige Frequenzen und hohe :Spannungen, benötigt man lange dünne Drähte und kostspielige Wickelmaschinen.For the production of induction coils, especially for low frequencies and high: tensions, you need long thin wires and expensive winding machines.
Drahtbrüche und Windungskurzschlüsse sind häufige Erscheinungen. Die Technik der gedruckten Schaltungen hat einen Weg gezeigt, auf dem die Massenanfertigung von Wicklungen auf Scheiben aus Isolierstoffen verbilligt werden kann. Doch bleibt die Induktion einer gedruckten Flachspule stets begrenzt.Wire breaks and winding shorts are common occurrences. the Printed circuit technology has shown a way on which to mass manufacture of windings on disks made of insulating materials can be made cheaper. But remains the induction of a printed flat coil is always limited.
Durch Aufeinanderstapeln von mehreren Flachspulen h at man versucht, die Induktion zu erhöhen, doch machen sich die Kontaktstellen zwischen je zwei Spulen unangenehm bemerkbar. Das Verlöten oder Verschweißen der Spulenenden verteuert die Herstellung.By stacking several flat coils on top of one another, an attempt was made to to increase the induction, but make the contact points between each two coils uncomfortably noticeable. Soldering or welding the coil ends makes them more expensive Manufacturing.
Gegenstand dieser Erfindung ist, Induktionsspulen beliebig höher Windungszahlen ohne störende Kontaktstellen im Druck- oder Spritzverfahren oder auf galvanostegischem Wege herzustellen.The subject of this invention is induction coils of any number of turns without disturbing contact points in the printing or spraying process or on galvanostegic To create ways.
Ein langes Band aus dünnem Isolierstoff (Kunststoffolie, Papier, imprägniertes Gewebe) wird in gleichmäßigen Abständen mit runden oder eckigen Löchern versehen. Größe und Form der Löcher richten sich nach dem Querschnitt des vorgesehenen Eisenkerns. Um die Löcher herum werden auf beiden Seiten des Bandes spiralförmige Windungen aus elektroleitenden Stoffen durch Drucken, Spritzen oder galvanisch aufgelegt, wobei zwei gegenüberliegende Spiralen mit ihren inneren Enden durch eine 'kleine Öffnung im Isolierstoff Kontakt miteinander haben, <g, während die äußeren Enden zweier benachbarter Spiralen durch einen Steg miteinander verbunden sind, B. Alle Spiralen eines Bandes bilden eine ununterbrochene Leitung. Die äußeren Enden der ersten und der letzten Spirale erhalten Lötösen oder Klemmen, C. Anzapfungen können an den Stegen und äußeren Windungen angebracht werden. Das Band wird sodann im Zickzack gefaltet, so daß Öffnungen und Spiralen aufeinander zu liegen kommen. Falls die Spiralen nicht durch eine Lackschicht abgedeckt sind, können rechteckige Isolierplatten mit entsprechenden Öffnungen eingelegt werden. Bestehen diese aus guten Wärmeleitern und ragen über den Spulenrand hinaus, dann bilden sie Kühlrippen.A long strip of thin insulating material (plastic film, paper, impregnated Fabric) is provided with round or square holes at regular intervals. The size and shape of the holes depend on the cross-section of the intended iron core. Spiral turns are made around the holes on either side of the tape made of electroconductive materials by printing, spraying or galvanically applied, two opposing spirals with their inner ends passing through a 'small one Opening in the insulating material have contact with each other, <g, while the outer ends two adjacent spirals are connected to one another by a bar, B. All Spirals of a ribbon form a continuous line. The outer ends of the first and last spiral receive soldering lugs or terminals, C. taps can be attached to the webs and outer turns. The tape then zigzags folded so that openings and spirals come to rest on each other. if the Spirals are not covered by a layer of lacquer, rectangular insulating plates can be used be inserted with appropriate openings. Do these consist of good heat conductors and protrude beyond the edge of the coil, then they form cooling fins.
In die nunmehr fertige Spule kann ein Eisenkern in üblicher Weise eingeschichtet werden. Bei Trafos werden zwei oder mehrere Spulen zusammengelegt.An iron core can be inserted into the now finished coil in the usual way be layered. In the case of transformers, two or more coils are put together.
Billigere Herstellung, verkleinerter Wickelraum infolge rechteckigen Leitungsquerschnitts, bessere Wärmeableitung sind die wichtigsten Vorteile dieser Bauart.Cheaper production, reduced changing room due to rectangular Cable cross-section, better heat dissipation are the main advantages of this Design type.
Bei Spulen für höhere Frequenzen kann durch Einlage von elastischen Platten und veränderliche Pressung eine Variometerwirkung erreicht werden (abstimmbare Spulen).In the case of coils for higher frequencies, the insert of elastic Plates and variable pressure a variometer effect can be achieved (tunable Wash).
