Definitions
- the invention relates to a bobbin for winding with winding wire according to the preamble of claim 1.
- Such bobbins are for example from the DE 19 60 767 U and the US-A-3 566 322 known.
- bobbins for producing the winding are known for various variants of components with cores and at least one winding.
- Such bobbins are used in particular in cores of stamped sheets or cores (made of, for example, ferrite or various powder materials on iron or iron alloy) with divided core shapes such as E cores according to IEC 61246 or RM cores according to IEC 60431 in different embodiments.
- constructions with straight-out terminal pins which may in some cases also lie below the winding space of the copper coil, represent the optimum in terms of the consumption of building area.
- Such constructions are mainly used in the so-called RM Core shapes used.
- RM Core shapes used for use with E-cores, a construction is common in which the pins relative to the winding space of the copper coil are laterally offset and usually in two rows along the longitudinal axis of the component are arranged. Both constructions mentioned have in common that the winding of the copper wire must be done in a narrow area between the bobbin lower edge and the board surface to be equipped and the space available for it is very limited.
- the known constructions quickly come to constructive limits due to the copper cross sections of the winding wire required there.
- This problem is further exacerbated in devices made using copper braid to optimize RF performance since, in this case, the wire cross-section through segmentation in single cores is well above that of a cross-sectioned simple enameled wire and, more specifically, when using Litz with very thin single wires (eg ⁇ 0.15 mm) with a simple looping of the connecting pin no sufficient strength of the connection can be achieved, so that the stranded wire usually at least twice must be wrapped around the respective pin which, of course, the space required for Winding the wire further increased.
- the invention is therefore based on the object to propose an improved bobbin.
- the bobbin according to the invention is optimized on the one hand in terms of space requirements of the component and offers the Furthermore, the possibility of easier winding even thicker stranded wires to the pins.
- the bobbin usually produced by injection molding is produced in at least two separate part bodies, of which the first part body serves as a base or support plate for the connection pins and the second part body as a winding support for carrying the device winding. Other parts can be provided according to need and function.
- the pins are guided through openings in the winding carrier.
- the part body serving as a winding support is first wound with the required amount of enameled wire or stranded wire, and the wire ends are led out to the outside of the winding support through an opening on the side of the reel body into which the Anwickelloche are later inserted.
- the two body parts of the bobbin are brought together so that the pins are inserted through corresponding openings in the winding support.
- the bottom plate is fixed by corresponding locking fasteners on the winding support.
- Another advantage of the proposed design is that the Anschlußlötung the coil winding is spatially separated from the Montagelötung the device in the circuit board. A re-softening and in extreme cases a loosening of the connection of the winding wire to the soldering pin during the soldering of the component in a circuit board can thus be reliably excluded.
- the basic structure of a bobbin 1 according to the invention Fig. 1 The bobbin 1 consists of two partial bodies, namely a connection carrier 2 designed as a base plate and a winding support 3 for accommodating a winding consisting of winding wires.
- the winding support 3 has a cylindrical winding section 4 and a ceiling plate 5 extending perpendicularly thereto with two lateral guide segments 6, 7. Furthermore, the winding support 3 has a parallel to the ceiling plate 5 arranged base plate 13, for attachment to the bottom plate 2, on.
- the winding section 4 is thus bordered on two opposite sides for better retention of the winding.
- pins 10 are used, which have on the underside of the bottom plate over the standard length of 5 mm (about 1/5 inch) for attachment to a circuit board.
- the pin length on the opposite side of the bottom plate 2 depends on the height of the winding carrier 3.
- the pins 10 project beyond this by about 3 - 6 mm.
- the winding support 3 is first wound with the required amount of enameled wire or strand and the wire ends are guided freely through the openings 14 in the guide segments.

Description
Die Erfindung betrifft einen Spulenkörper zum Bewickeln mit Wicklungsdraht nach dem Oberbegriff des Patentanspruches 1.The invention relates to a bobbin for winding with winding wire according to the preamble of
Derartige Spulenkörper sind beispielsweise aus der
Für diverse Varianten von Bauelementen mit Kernen und mindestens einer Wicklung sind zahlreiche Varianten von spritzgegossenen Spulenkörpern zum Herstellen der Wicklung bekannt. Solche Spulenkörper werden insbesondere bei Kernen aus gestanzten Blechen oder Massekernen (hergestellt aus beispielsweise Ferrit oder diversen Pulverwerkstoffen auf Eisen oder Eisenlegierungsbasis) mit geteilten Kernformen wie etwa E-Kerne entsprechend IEC 61246-oder RM-Kernen entsprechend IEC 60431 in jeweils verschiedenen Ausführungsformen verwendet.Numerous variants of injection-molded bobbins for producing the winding are known for various variants of components with cores and at least one winding. Such bobbins are used in particular in cores of stamped sheets or cores (made of, for example, ferrite or various powder materials on iron or iron alloy) with divided core shapes such as E cores according to IEC 61246 or RM cores according to IEC 60431 in different embodiments.
Im Normalfall handelt es sich um vergleichsweise einfache Konstruktionen für die Verarbeitung auf Spindelwickelmaschinen. Das Anwickeln des die Wicklung bildenden Kupferlackdrahtes erfolgt durch Umschlingen der Anschlussstifte mit dem Lackdraht und anschließende Verlötung mit einem Weichlot zur Herstellung einer elektrischen Kontaktierung zwischen dem Lackdraht und dem jeweiligen Anschlussstift. Als Anschlussstifte sind dabei sowohl gerade als auch verschiedene abgewinkelte Rund- oder Flachstifte gebräuchlich, die in die der Leiterplatte gegenüberliegende Seite des Spulenkörpers entweder eingespritzt oder eingenagelt werden.Normally, these are comparatively simple constructions for processing on spindle winding machines. The winding of the winding forming copper enamel wire is done by looping the pins with the enameled wire and then soldering with a soft solder to make an electrical contact between the enameled wire and the respective pin. As pins are both straight and various angled round or flat pins in use, which are either injected or nailed into the circuit board opposite side of the bobbin.
Was den erforderlichen Bauraum auf der zu bestückenden Platinenoberfläche betrifft, stellen Konstruktionen mit gerade herausgeführten Anschlussstiften, die teilweise auch noch unter dem Wickelraum der Kupferspule liegen können, das Optimum in Bezug auf den Verbrauch an Baufläche dar. Derartige Konstruktionen werden vor allem bei den sogenannten RM-Kernformen verwendet. Für die Verwendung bei E-Kernen ist eine Konstruktion üblich, bei der die Anschlussstifte gegenüber dem Wickelraum der Kupferspule seitlich versetzt sind und in der Regel in zwei Reihen entlang der Längsachse des Bauelementes angeordnet sind. Beiden genannten Konstruktionen ist gemeinsam, dass das Anwickeln des Kupferdrahtes in einem schmalen Bereich zwischen Spulenkörperunterkante und der zu bestückenden Platinenoberfläche erfolgen muss und der dafür zur Verfügung stehende Raum sehr begrenzt ist.Concerning the required installation space on the board surface to be populated, constructions with straight-out terminal pins, which may in some cases also lie below the winding space of the copper coil, represent the optimum in terms of the consumption of building area. Such constructions are mainly used in the so-called RM Core shapes used. For use with E-cores, a construction is common in which the pins relative to the winding space of the copper coil are laterally offset and usually in two rows along the longitudinal axis of the component are arranged. Both constructions mentioned have in common that the winding of the copper wire must be done in a narrow area between the bobbin lower edge and the board surface to be equipped and the space available for it is very limited.
Durch die Verwendung von Spulenkörpern mit abgewinkelten Stiften bzw. mit vergrößerten Grundplatten lässt sich dieses Problem umgehen - der Platzbedarf des Bauelementes steigt durch diese Maßnahmen jedoch entsprechend.By using bobbins with angled pins or with enlarged base plates, this problem can be avoided - the space requirement of the component increases by these measures, however, accordingly.
Speziell bei der Herstellung von Bauelementen für Leistungsanwendungen stoßen daher die bekannten Konstruktionen auf Grund der dort erforderlichen Kupferquerschnitte des Wicklungsdrahtes schnell an konstruktive Grenzen. Dieses Problem wird bei Bauelementen, die unter Verwendung von Kupferlitze zur Optimierung der HF-Eigenschaften hergestellt werden, noch weiter verschärft da hier zum einem der Drahtquerschnitt durch die Segmentierung in Einzeladern deutlich über dem eines querschnittsgleichen einfachen Lackdrahtes liegt und zum anderen speziell bei der Verwendung von Litze mit sehr dünnen Einzeladern (z.B. < 0,15 mm) mit einer einfachen Umschlingung des Anschlussstiftes keine hinreichende Festigkeit der Verbindung zu erreichen ist, so dass der Litzendraht in der Regel mindestens zweimal um den jeweiligen Anschlussstift geschlungen werden muss was natürlich den Platzbedarf für das Anwickeln des Drahtes weiter erhöht.Especially in the manufacture of components for power applications, therefore, the known constructions quickly come to constructive limits due to the copper cross sections of the winding wire required there. This problem is further exacerbated in devices made using copper braid to optimize RF performance since, in this case, the wire cross-section through segmentation in single cores is well above that of a cross-sectioned simple enameled wire and, more specifically, when using Litz with very thin single wires (eg <0.15 mm) with a simple looping of the connecting pin no sufficient strength of the connection can be achieved, so that the stranded wire usually at least twice must be wrapped around the respective pin which, of course, the space required for Winding the wire further increased.
Der Erfindung liegt daher die Aufgabe zugrunde, einen verbesserten Spulenkörper vorzuschlagen.The invention is therefore based on the object to propose an improved bobbin.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is solved by the features of
Der erfindungsgemäße Spulenkörper ist zum Einen hinsichtlich des Platzbedarfs des Bauelementes optimiert und bietet des Weiteren die Möglichkeit des erleichterten Anwickelns auch dickerer Litzendrähte an die Anschlussstifte.The bobbin according to the invention is optimized on the one hand in terms of space requirements of the component and offers the Furthermore, the possibility of easier winding even thicker stranded wires to the pins.
Dies wird dadurch erreicht, dass der meist im Spritzgussverfahren hergestellte Spulenkörper in mindestens zwei getrennten Teilkörpern hergestellt wird, von denen der erste Teilkörper als Boden- bzw. Trägerplatte für die Anschlussstifte und der zweite Teilkörper als Wicklungsträger zum Tragen der Bauelementewicklung dient. Weitere Teilkörper können je nach Bedarf und Funktion vorgesehen werden. Die Anschlussstifte sind dabei durch Öffnungen im Wicklungsträger geführt.This is achieved in that the bobbin usually produced by injection molding is produced in at least two separate part bodies, of which the first part body serves as a base or support plate for the connection pins and the second part body as a winding support for carrying the device winding. Other parts can be provided according to need and function. The pins are guided through openings in the winding carrier.
Bei Herstellung eines Bauelementes wird zunächst der als Wicklungsträger dienende Teilkörper mit der erforderlichen Menge an Lackdraht bzw. Litze bewickelt und die Drahtenden frei durch eine Öffnung auf der Seite des Spulenkörpers, in welche später die Anwickelstifte eingesetzt werden, an die Außenseite des Wicklungsträgers herausgeführt. Nach Fertigstellung der Wicklung werden die beiden Teilkörper des Spulenkörpers so zusammengeführt, dass die Anschlussstifte durch entsprechende Öffnungen im Wicklungsträgers gesteckt werden. Beim endgültigen Zusammenfügen der beiden Teilkörper wird die Bodenplatte durch entsprechende rastende Verbindungselemente am Wicklungsträger fixiert.In the manufacture of a component, the part body serving as a winding support is first wound with the required amount of enameled wire or stranded wire, and the wire ends are led out to the outside of the winding support through an opening on the side of the reel body into which the Anwickelstifte are later inserted. After completion of the winding, the two body parts of the bobbin are brought together so that the pins are inserted through corresponding openings in the winding support. During the final assembly of the two body parts, the bottom plate is fixed by corresponding locking fasteners on the winding support.
Nach diesem Montageschritt werden die einzelnen, zuvor losen Draht- oder Litzenenden, an die jeweiligen Anschlussstifte angewickelt und anschließend mit diesen verlötet.After this assembly step, the individual, previously loose wire or stranded ends are wound on the respective pins and then soldered to them.
Durch die Erfindung lassen sich auch voluminöse Lötanschlüsse mit mehr als einer Umschlingung und unter Verwendung von HF-Litze größeren Querschnitts an den nach Bauflächenbedarf optimierten Spulenkörpern anbringen. Der Bauraum unmittelbar oberhalb des Spulenkörpers, der in der vorgestellten Konstruktion zur Ausführung der Anschlusslötung Verwendung findet, wird in konventionellen Konstruktionen nicht genutzt, so dass sich durch die vorgeschlagene Konstruktion letztendlich eine Erhöhung der Packungsdichte auf einer Platine erreichen lässt.By means of the invention, it is also possible to attach voluminous solder connections with more than one loop and using HF stranded wire of larger cross-section to the bobbins optimized according to construction area requirements. The space immediately above the bobbin, which is used in the presented construction for performing the Anschlusslötung, is not used in conventional constructions, so that ultimately by the proposed construction achieve an increase in packing density on a board.
Ein weiterer Vorteil der vorgeschlagenen Bauform besteht darin, dass die Anschlusslötung der Spulenwicklung räumlich von der Montagelötung des Bauelementes in der Leiterplatte getrennt wird. Eine Wiedererweichung und im Extremfall ein Lösen der Verbindung des Wicklungsdrahtes zum Lötstift während des Einlötens des Bauelementes in eine Leiterplatte kann somit zuverlässig ausgeschlossen werden.Another advantage of the proposed design is that the Anschlußlötung the coil winding is spatially separated from the Montagelötung the device in the circuit board. A re-softening and in extreme cases a loosening of the connection of the winding wire to the soldering pin during the soldering of the component in a circuit board can thus be reliably excluded.
