Description

Die Erfindung betrifft eine Lötfahne zur Befestigung von elektrischen Leitungs- und Wicklungsdrähten und insbesondere eine Lötfahne, die in einem Spulenkörperflansch einer elektrischen Spule gehaltert ist.The invention relates to a soldering lug for fastening electrical lead and winding wires, and in particular to a soldering lug which is held in a coil body flange of an electrical coil.

Die bereits bekannten, in die Flansche der Spulenkörper elektrischer Spulen eingesetzten stift- oder hakenförmigen Lötfahnen müssen zur Fixierung der Wickeldrahtenden meist mit dem Spulendraht umwickelt werden. Bekannt sind auch Lötfahnen, bei denen die Wickeldrahtenden durch mechanische Deformation der Lötfahne eingeklemmt und dadurch fixiert werden. Alle diese bekannten Ausführungen bedingen einen erheblichen Zeitaufwand für die Fixierung der Wickeldrahtenden, wobei zum Teil zusätzliche, von Hand betätigbare Hilfsmittel notwendig sind, die nur schwer automatisierbar sind.The already known pin or hook-shaped soldering lugs inserted into the flanges of the coil bodies of electrical coils usually have to be wrapped with the coil wire in order to fix the winding wire ends. Solder tags are also known, in which the ends of the winding wires are pinched by mechanical deformation of the solder tag and are thereby fixed. All of these known designs require a considerable amount of time for fixing the winding wire ends, some additional, manually operable aids which are difficult to automate being necessary.

Die in Fig. 1 teilweise gebrochen und in Draufsicht dargestellte, bekannte blättchenförmige Lötfahne 1 besitzt eine kerbenartige randoffene-Ausnehmung 2, in die das Wickeldrahtende einklemmbar-ist. Der Nachteil dieser Lötfahne ist ihre starre Ausführung, die auf den jeweiligen Drahtdurchmesser abgestimmt sein muß. Unterschiedliche Drahtstärken erfordern demzufolge jeweils eine andere Lötfahnenausführung. Außerdem besteht hier stets die Gefahr, daß die Drähte beim Fixieren durch eine scharfkantige Kerbe durchgetrennt werden.The known flake-shaped soldering lug 1, partially broken and shown in plan view in FIG. 1, has a notch-like edge-open recess 2, into which the end of the winding wire can be clamped. The disadvantage of this solder tail is its rigid design, which must be matched to the wire diameter. Different wire sizes therefore require a different solder lug design. In addition, there is always the risk that the wires will be cut through by a sharp-edged notch when fixing.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Lötfahne zu schaffen, die auf einfache, zerstörungsfreie und schnelle Weise die Möglichkeit bietet, unterschiedlich starke elektrische Leitungsdrähte, insbesondere Wickeldrähte, bis zum Abschluß des Lötvorganges sicher in ihrer Lage zu fixieren; insbesondere soll diese Lötfahne zum Einsatz in elektrischen Spulen geeignet sein, deren Bewicklung automatisch erfolgt.The present invention has for its object to provide a solder tail that offers the possibility in a simple, non-destructive and quick way to fix differently strong electrical lead wires, in particular winding wires, securely in position until the completion of the soldering process; in particular, this soldering tag should be suitable for use in electrical coils, which are wound automatically.

Zur Lösung dieser Aufgabe sieht die Erfindung bei einer Lötfahne der eingangs genannten Art vor, daß diese mindestens in ihrem zur Befestigung der elektrischen Leitungsdrähte bzw. Wickeldrahtenden dienenden freien Ende aus geschichteten, V-förmig gespreizten Blattfedern bzw. aus einem blättchenförmigen Material mit federnden Eigenschaften gebildet ist.To achieve this object, the invention provides for a solder tail of the type mentioned, that these free at least in its serving for fixing the electric wires or the winding wire ends end of layered V-shaped spread leaf springs or from a blättchenförmi g s material with resilient Properties is formed.

Durch diese Lötfahne ist der Draht selbst bei unterschiedlicher Drahtstärke rasch und sicher fixierbar. Allein durch das Einziehen des Drahtes zwischen die gespreizten Blattfederenden ist bereits eine für den anschließenden Lötvorgang ausreichende Halterung des Drahtes gewährleistet. Ein zusätzliches Umwickeln der Lötfahne mit dem Draht, das bisher üblich und sehr aufwendig ist, kann entfallen. Durch das Einziehen der üblicherweise elektrisch isolierten Wickeldrahtenden in die Lötfahne wird die Lackisolierung an der zu lötenden Stelle aufgerissen und dadurch eine sichere und schnelle Lötung ermöglicht.With this soldering lug, the wire can be fixed quickly and securely even with different wire thicknesses. Only by pulling the wire between the spread ends of the leaf springs is it sufficient to hold the wire sufficiently for the subsequent soldering process. An additional wrapping around the Solder tail with the wire, which was previously common and very expensive, can be omitted. By pulling the usually electrically insulated winding wire ends into the solder lug, the lacquer insulation is torn open at the point to be soldered, thereby enabling safe and quick soldering.

Diese Art der Halterung gewährleistet eine erheblich höhere Wirtschaftlichkeit gegenüber den bisher angewendeten Fixier- und Lötverfahren. Insbesondere beim automatischen Bewickeln von Spulenkörpern schafft diese Lötfahne erhebliche Vorteile, da die Wickelautomaten die Wickeldrahtenden unmittelbar in die Lötfahne einziehen und fixieren können.This type of holder ensures a significantly higher economy compared to the previously used fixing and soldering processes. This soldering lug creates considerable advantages, in particular in the case of automatic winding of coil formers, since the automatic winding machines can pull the winding wire ends directly into the soldering lug and fix them.
