Abstract
Description
Die Erfindung betrifft einen Spulenkörper für elektrische Spulen, mit am Spulenkörperflansch angeformten Lötanschlußleisten mit in Reihe angeordneten Lötösen-Anschlüssen, deren eine Enden Lötösen zum Be= und Anwickeln von Wickeldrahtenden und deren andere Enden Stifte zum Aufsetzen auf Leiterplatten sind.The invention relates to a bobbin for electrical coils with molded on the bobbin flange solder terminal strips with series-arranged soldering eye connections, one end of which is for the loading and winding of winding wire ends and the other ends of which are pins for mounting on printed circuit boards.
Bei elektrischen Spulen, die z.B. aus einem bewickelten Spulenkörper und Ferrit-E-Kernhälften bestehen, die mit ihren Mittelbutzen in den Spulenkörper eintauchen, bei denen hauptsächlich im Sekundärkreis größere elektrische Ströme fließen, sind wegen der dort auftretenden Strombelastung im allgemeinen dickere Drähte, deren Durchmesser mindestens 0,45 mm beträgt und Litzen erforderlich. Beim Anwickeln derart starker Wickeldrähte an gerade Anschlußstifte besteht die Gefahr, daß diese, üblicherweise als Wicklungslocken bezeichneten Drahtenden aufspringen. Beim anschließenden Anlöten der Wickeldrahtenden an die Anschlußstifte und ggf. bereits an die entsprechenden Leiterbahnen gedruckter Leiterplatten können hierdurch sogenannte "kalte Lötstellen" und Kontaktbrücken zu benachbarten Anschlußstiften entstehen. Es ist deshalb notwendig, daß die Wicklungsenden in ihrer Lage zum Spulenkörperanschluß bzw. jeweiligen Anschlußstift eindeutig, d.h. entweder form- oder kraftschlüssig definiert sind. Außerdem sollen auch dünnere Wickeldrähte, z.B. Drähte in Litzenstärke mittels Wickelautomaten selbsttätig an die Anschlußstifte anwickelbar sein.With electrical coils, e.g. consist of a wound bobbin and ferrite E core halves, which dip into the bobbin with their central slugs, in which larger electrical currents flow mainly in the secondary circuit, are generally thicker wires with a diameter of at least 0.45 mm due to the current load occurring there and strands required. When such strong winding wires are wound onto straight connection pins, there is a risk that these wire ends, usually referred to as winding curls, will spring open. When the winding wire ends are subsequently soldered onto the connecting pins and possibly already onto the corresponding conductor tracks of printed circuit boards, this can result in so-called “cold soldering points” and contact bridges to adjacent connecting pins. It is therefore necessary that the winding ends are unambiguous in their position in relation to the coil former connection or respective connecting pin, i.e. are defined either positively or non-positively. In addition, thinner winding wires, e.g. Wires in strand thickness can be automatically wound onto the connecting pins by means of automatic winding machines.
Rechtwinklige Lötösen-Anschlüsse, welche die Forderung hinsichtlich der Fixierung dicker Drähte und Litzen erfüllen, sind z.B. bei den in FIG 1, 1a dargestellten, bekannten EC-Spulenkörpern im Einsatz. Grundsätzlich lassen sich auch sehr dünne Drähte an derartige Lötösen-Anschlüsse anwickeln; hierzu ist aber eine relative Schwenkbewegung zwischen Spulenkörper und Drahtführer des Wickelautomaten von 90° - Stellung Bewickeln - Stellung Anwickeln - notwendig. Der ohnehin zeitaufwendige Anwickelvorgang wird dadurch nochmals verzögert.Right-angled soldering eye connections, which meet the requirements with regard to the fixing of thick wires and strands, are used, for example, in the known EC coil formers shown in FIGS. 1, 1a. In principle, very thin wires can also be wound onto such soldering eye connections; but this is a relative pivoting movement between the bobbin and wire guide of the automatic winder from 90 ° - winding position - winding position - necessary. This further delays the already time-consuming start-up process.
Die Lötösen-Anschlüsse dieser bekannten EC-Spulenkörper sind Stanzteile, die verzinnt und in schlitzförmige Ausnehmungen der abgespritzten Spulenkörper nachträglich eingesetzt werden müssen. Die Fertigungsschritte Stanzen, Verzinnen und Bestücken erfordern dabei einen erheblichen Aufwand und versteuern so die Spulenkörper.The solder eyelet connections of these known EC bobbins are stamped parts which are tin-plated and have to be subsequently inserted into the slot-shaped recesses in the sprayed bobbin. The manufacturing steps of stamping, tinning and equipping require considerable effort and thus tax the coil formers.
Aus der EP-A-0 304 593 ist ein SMD-Baustein mit einem Anschlußelement bekannt, das in seinem Endbereich zu einer U-förmigen Lasche zurückgebogen ist, wodurch zwischen den Schenkeln dieser U-förmigen Lasche ein Anschlußdraht klemmend gehalten werden kann.From EP-A-0 304 593 an SMD module with a connection element is known, which is bent back in its end region to a U-shaped tab, whereby a connecting wire can be held clamped between the legs of this U-shaped tab.
Aus der DE-A-31 38 936 ist eine in einem Trägerkörper eines Spulenkörpers gehaltene winkelige Lötfahne bekannt, die zwei rechtwinklig zueinander stehende Schenkel aufweist, von denen einer ein hakenförmiges Ende und einer ein spitz zulaufendes Ende aufweist. Die hakenförmigen Enden können dabei beispielsweise zur Befestigung der Wicklungsenden einer auf dem Spulenkörper angeordneten elektrischen Wicklung dienen, während die spitz zulaufenden Enden beispielsweise auf einer Schaltungsplatine verlötet werden können.From DE-A-31 38 936 an angular soldering tab is known which is held in a carrier body of a coil body and has two legs standing at right angles to one another, one of which has a hook-shaped end and one has a tapering end. The hook-shaped ends can serve, for example, for fastening the winding ends of an electrical winding arranged on the coil former, while the tapering ends can be soldered, for example, to a circuit board.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Spulenkörper für elektrische Spulen der eingangs genannten Art zu schaffen, der mit geringem Aufwand herstellbar und zusätzlich zum automatischen Anwickeln selbst äußerst dünner Drähte, z. B. in Litzenstärke geeignet ist.The present invention has for its object to provide a bobbin for electrical coils of the type mentioned, which can be produced with little effort and in addition to automatically winding even extremely thin wires, for. B. is suitable in strand thickness.
Zur Lösung dieser Aufgabe sieht die Erfindung beim Spulenkörper gemäß Oberbegriff des Anspruchs vor, daß die Lötösen-Anschlüsse in die Lötanschlußleisten eingesetzte rechtwinklige Drahtstifte sind, deren eine Enden U-förmig gekrümmt sind, und daß der Abstand zwischen den Lötanschlußleisten und den Stirnflächen der U-förmig gekrümmten Enden mindestens so groß gewählt ist, daß Drähte, bevorzugt Rund- oder Vierkantdrähte selbst in Litzenstärke automatisch an diese Enden anwickelbar sind.To achieve this object, the invention provides for the bobbin according to the preamble of the claim that the solder eyelet connections are inserted into the solder connection strips rectangular wire pins, one end of which is curved in a U-shape, and that the distance between the solder connection strips and the end faces of the U- shaped curved ends is chosen at least so large that wires, preferably round or square wires, even with stranded wire, can be automatically wound onto these ends.
Bedingt durch die Verwendung von Drahtstiften als Lötösen-Anschlüsse, können diese fortlaufend von einer Drahtrolle abgezogen und beim Spritzen des Spulenkörpers unmittelbar in die Lötanschlußleisten des Spulenkörpers eingespritzt werden, wobei gleichzeitig eine automatische U-förmige Krümmung eines der beiden Drahtstiftenden möglich ist.Due to the use of wire pins as solder eye connections, these can be continuously withdrawn from a wire reel and injected directly into the solder terminal strips of the coil body when the coil body is being sprayed, an automatic U-shaped curvature of one of the two wire pin ends being possible at the same time.
Bei Verwendung von Litzen und dicken Drähten als Spulenwickeldrähte werden diese durch den ggf. teils im Spulenkörperflansch und teils in den Lötanschlußleisten ausgebildeten Drahtausführungsschlitz und durch das U-förmig gekrümmte Ende des Lötanschlusses gezogen, wobei sich die Litzen bzw. Drähte zwischen der Lötanschlußleiste und dem Lötanschluß verklemmen. Zusätzlich werden dadurch die Wicklungsenden gegen Verrutschen gesichert.If strands and thick wires are used as coil winding wires, these are formed by the wire execution slot, which may be formed partly in the coil former flange and partly in the solder connection strips, and by the U-shaped curved end of the solder connection pulled, with the strands or wires jamming between the solder terminal block and the solder connection. In addition, the winding ends are secured against slipping.
Wenn der Abstand zwischen der Lötanschlußleiste, in welche der Lötösen-Anschluß eingebettet ist, und den Stirnflächen seiner u-förmig gekrümmten Enden mindestens so groß gewählt ist, daß das Drahtführungsröhrchen eines Wickelautomaten durch den so geschaffenen Zwischenraum "hindurchtaumeln" kann, können auch dünnere Drähte automatisch an den Lötösen-Anschluß angewickelt werden, ohne daß nach dem Bewickeln des Wickelträgers des Spulenkörpers zum Zwecke des Anwickelns des Wickeldrahtendes an die Lötöse eine Schwenkbewegung des Drahtführungsröhrchens erfolgen muß.If the distance between the solder connection strip, in which the soldering eye connection is embedded, and the end faces of its U-shaped curved ends is chosen at least so large that the wire guide tube of an automatic winder can "tumble" through the intermediate space thus created, thinner wires can also be used are automatically wound onto the soldering eye connection without having to perform a pivoting movement of the wire guide tube after winding the winding support of the coil former for the purpose of winding the end of the winding wire onto the soldering eye.
