Definitions
- the invention relates to a bobbin with a continuous recess for receiving a double-shell core, with a winding body, at both ends of which flanges are formed, with at least one flange being formed in a direction extending transversely to the longitudinal axis of the recess, the at least three arranged side by side Solder connections for wrapped around the winding body. Has winding wires.
- Such a known coil body has solder tabs with an approximately rectangular flat cross section, the width of which is considerably greater than the height, as the solder connections. Ends of the winding wires, which form windings on the winding former, are wound around these soldering tags. Then the winding wires are connected to the solder lugs by soldering. During this soldering process, changes in length occur in the winding wire due to the high soldering temperature and the subsequent cooling, which increase the tensile stress in the winding wire, as a result the soldering quality is impaired and damage or tearing of the winding wire can occur during operation under fluctuating working temperatures.
- solder connections are designed as essentially cylindrical pins which are embedded vertically projecting in spaced-apart bases, and in that each base is rounded on the side facing the associated pin and carries a deflection device around which the winding wire is deflected before wrapping the pin.
- the solder connections are designed as essentially cylindrical pins.
- the cylindrical shape allows the end of a winding wire to be wrapped tightly around the pin without the risk of the winding wire tearing off at sharp edges.
- the pins are embedded in spaced bases that are rounded. It is thereby achieved that the supply of the winding wire to the pin is problem-free since the winding wire easily slides over the base due to the rounding even if the coil former is incorrectly aligned with respect to a winding device and does not get caught.
- a deflection device is also provided, around which the winding wire is deflected before the pin is wrapped. This deflection device forms a strain relief for the winding wire, so that the tensile stresses occurring during soldering are absorbed.
- the deflection device is preferably designed as a deflection pin projecting radially from the coil body on the base. This arrangement makes it possible to optimally design the sequence of movements of the winding device and the bobbin relative to one another in a numerically controlled automatic winding machine, since only swiveling movements of 90 ° have to be carried out.
- the use of a cylindrical deflection pin reduces the risk of the winding wire tearing off, even when the winding wire guide is tight.
- the terminal block carries on the side facing the winding body a wall projecting in the longitudinal direction of the coil body, which has a predetermined distance from the bases, which is used to pass the winding wire or the winding wires.
- the wall carries a vertically projecting spacer, the end of which exceeds the height of the winding wire wound on the pin.
- This spacer is used to produce a defined distance from the printed circuit board, so that the end of the winding wire wound and soldered to the pin has a sufficient distance from through holes in the printed circuit board and blind soldering cannot occur as a result of covered through holes.
- FIG 1 an embodiment of a bobbin 10 according to the invention is shown in perspective.
- the bobbin 10 has a winding body 12 with a continuous recess 14 for receiving a double-shell core 16, which is shown in the figure above.
- Flanges 16, 18 are formed on the winding body 12 at its ends, which limit the windings (not shown) on the winding body 12 at the edges.
- the terminal strips 20, 22 carry pins 28, of which only one is provided with the reference number 28 for a better overview.
- the pins 28 are aligned on both connecting strips 20, 22 along a straight line and have a substantially cylindrical shape.
- the pins 28 are embedded in bases 30, only one of which is provided with the reference symbol 30.
- a deflection pin 32 projects perpendicularly to the axis of the pin 28 on each base 30 and has a cylindrical shape.
- Each base 30 has a rounding 34 toward the top of the pin 28.
- Each terminal block 20, 22 carries, on the side facing the winding body 12, a wall 36 which projects in the longitudinal direction of the coil body 10 and which is at a predetermined distance from the bases 30. This creates a guideway 38 which is used to feed the respective winding wire to the pins 28.
- Each wall 36 carries spacer elements 40 which set a defined distance from a printed circuit board (not shown).
- the height of the respective spacer element 40 is designed so that a winding wire wound on the pin 28 and the associated solder have a sufficient distance from the printed circuit board and the end of the winding wire or the soldering pads does not clog the through hole on the printed circuit board into which the pin 28 is inserted . This prevents incorrect soldering.
- the two flanges 16, 18 each have a straightening recess 42 (only the lower straightening recess 42 can be seen) for a winding mandrel of the winding machine.
- This directional recess thus defines the positional relationship between the bobbin 10 and the winding machine.
- the double-shell core 16 shown in the upper part of the figure has a central column part 44 which fits into the recess 14 of the winding body 12.
- the outer shape of the magnetic core 16 is such that the upper and the lower section 46 are approximately flush with the inner surfaces of the terminal strips 20, 22 and abutment surfaces 48.
- FIG. 2 schematically shows the course of a winding wire 50 from the winding body 12 to the pin 28.
- the winding wire 50 is guided through the recess 24 over the guideway 38 and, between two bases 30, reaches the deflecting pin 32, through which it is deflected.
- the winding wire 50 is then guided to the base of the pin 28, wherein it rests on the rounding 34.
- the winding wire 50 is then wound around the pin 28.
- the deflection of the winding wire around the deflecting pin 32 results in a strain relief, so that the risk of damage or tearing is reduced even when the winding wire guide is tight.
- the rounding 34 enables winding wire guidance without the winding wire 50 becoming caught.
- FIG. 3 shows a plan view of the coil former 10 according to FIG. 1, and makes it easier to see parts which are hidden in FIG. 1. The same parts are provided with the same reference numerals.
- the pins 28 of the two terminal strips lie in planes parallel to the longitudinal axis of the coil body 10 and point in the same direction. This makes it possible to wrap the wound ends of the winding wires on all pins 28 in a single soldering operation, e.g. by dip soldering.
- the pins 28 preferably have a pair of flattened side surfaces so that a cylindrical shape is formed which is flattened laterally. Furthermore, the cylindrical surface has a corrugation. The edge created in the transition area between the flat side surface and the cylinder surface serves as a tear-off edge for the wound winding wire. Further details on the design of the pins 28 are described in German utility model 295 12 324.9, the content of which belongs to the disclosure content of the present application.

Abstract
Description
Die Erfindung betrifft einen Spulenkörper mit einer durchgehenden Ausnehmung für die Aufnahme eines zweischaligen Kerns, mit einem Wickelkörper, an dessen beiden Enden Flansche ausgebildet sind, wobei an mindestens einem Flansch eine in Querrichtung zur Längsachse der Ausnehmung erstreckende Anschlußleiste ausgebildet ist, die mindestens drei nebeneinander angeordnete Lötanschlüsse für um den Wickelkörper gewickelte. Wickeldrähte hat.The invention relates to a bobbin with a continuous recess for receiving a double-shell core, with a winding body, at both ends of which flanges are formed, with at least one flange being formed in a direction extending transversely to the longitudinal axis of the recess, the at least three arranged side by side Solder connections for wrapped around the winding body. Has winding wires.
Ein derartiger bekannter Spulenkörper hat als Lötanschlüsse Lötfahnen mit annähernd rechteckigem flachen Querschnitt, dessen Breite erheblich größer ist als die Höhe. Um diese Lötfahnen werden Enden der Wickeldrähte gewickelt, welche Wicklungen auf dem Wickelkörper bilden. Anschließend werden die Wickeldrähte mit den Lötfahnen durch Löten verbunden. Bei diesem Lötvorgang treten infolge der hohen Löttemperatur und dem nachfolgenden Abkühlen Längenänderungen im Wickeldraht auf, welche die Zugspannung im Wickeldraht erhöhen, wodurch die Lötqualität beeinträchtigt wird und eine Beschädigung oder ein Abreißen des Wickeldrahtes während des Betriebs unter schwankenden Arbeitstemperaturen auftreten kann. Außerdem ist beim bekannten Spulenkörper das Umwickeln einer Lötfahne mit dem Wickeldraht in einer automatischen Wickelmaschine aufwendig, da die Führung des Wickeldrahtes vom Wickelkörper zur Lötfahne kompliziert ist und an den Kanten der Lötfahnen bei straffer Wickeldrahtführung der Wickeldraht abreißen kann.Such a known coil body has solder tabs with an approximately rectangular flat cross section, the width of which is considerably greater than the height, as the solder connections. Ends of the winding wires, which form windings on the winding former, are wound around these soldering tags. Then the winding wires are connected to the solder lugs by soldering. During this soldering process, changes in length occur in the winding wire due to the high soldering temperature and the subsequent cooling, which increase the tensile stress in the winding wire, as a result the soldering quality is impaired and damage or tearing of the winding wire can occur during operation under fluctuating working temperatures. In addition, in the known coil former, the wrapping of a solder lug with the winding wire in an automatic winding machine is complex, since the guidance of the winding wire from the winding body to the soldering lug is complicated and the winding wire can tear off at the edges of the soldering lugs with a tight winding wire guide.
Es ist Aufgabe der Erfindung, einen Spulenkörper anzugeben, der ein einfaches automatisches Wickeln gestattet und der betriebssicher arbeitet.It is an object of the invention to provide a bobbin that allows simple automatic winding and that works reliably.
Diese Aufgabe wird für einen Spulenkörper eingangs genannter Art dadurch gelöst, daß die Lötanschlüsse als im wesentlichen zylindrische Stifte ausgebildet sind, die vertikal abstehend in voneinander beabstandeten Sockeln eingebettet sind, und daß jeder Sockel auf der dem zugeordneten Stift zugewandten Seite abgerundet ist und eine Umlenkvorrichtung trägt, um die der Wickeldraht vor dem Umwickeln des Stiftes umgelenkt ist.This object is achieved for a coil former of the type mentioned in that the solder connections are designed as essentially cylindrical pins which are embedded vertically projecting in spaced-apart bases, and in that each base is rounded on the side facing the associated pin and carries a deflection device around which the winding wire is deflected before wrapping the pin.
Bei der Erfindung sind die Lötanschlüsse als im wesentlichen zylindrische Stifte ausgebildet. Die Zylinderform gestattet ein straffes Umwickeln des Stiftes mit dem Ende eines Wickeldrahtes, ohne daß die Gefahr eines Abreißens des Wickeldrahtes an scharfen Kanten entsteht. Die Stifte sind in voneinander beabstandeten Sockeln eingebettet, die abgerundet sind. Dadurch wird erreicht, daß die Zuführung des Wickeldrahtes zum Stift problemlos ist, da der Wickeldraht aufgrund der Abrundung auch bei fehlerhafter Ausrichtung des Spulenkörpers in bezug auf eine Wickelvorrichtung leicht über den Sockel gleitet und sich nicht verhakt. Erfindungsgemäß ist ferner eine Umlenkvorrichtung vorgesehen, um die der Wickeldraht vor dem Umwickeln des Stiftes umgelenkt ist. Diese Umlenkvorrichtung bildet eine Zugentlastung für den Wickeldraht, so daß die beim Löten auftretenden Zugspannungen abgefangen werden.In the invention, the solder connections are designed as essentially cylindrical pins. The cylindrical shape allows the end of a winding wire to be wrapped tightly around the pin without the risk of the winding wire tearing off at sharp edges. The pins are embedded in spaced bases that are rounded. It is thereby achieved that the supply of the winding wire to the pin is problem-free since the winding wire easily slides over the base due to the rounding even if the coil former is incorrectly aligned with respect to a winding device and does not get caught. According to the invention, a deflection device is also provided, around which the winding wire is deflected before the pin is wrapped. This deflection device forms a strain relief for the winding wire, so that the tensile stresses occurring during soldering are absorbed.
Vorzugsweise ist die Umlenkvorrichtung als radial vom Spulenkörper am Sockel abstehender Umlenkzapfen ausgebildet. Durch diese Anordnung ist es möglich, den Bewegungsablauf von Wickelvorrichtung und Spulenkörper zueinander in einem numerisch gesteuerten Wickelautomaten optimal zu gestalten, da lediglich Schwenkbewegungen um 90° ausgeführt werden müssen. Die Verwendung eines zylindrischen Umlenkzapfens reduziert die Gefahr des Abreißens des Wickeldrahtes auch bei straffer Wickeldrahtführung.The deflection device is preferably designed as a deflection pin projecting radially from the coil body on the base. This arrangement makes it possible to optimally design the sequence of movements of the winding device and the bobbin relative to one another in a numerically controlled automatic winding machine, since only swiveling movements of 90 ° have to be carried out. The use of a cylindrical deflection pin reduces the risk of the winding wire tearing off, even when the winding wire guide is tight.
Gemäß einem Ausführungsbeispiel der Erfindung trägt die Anschlußleiste auf der dem Wickelkörper zugewandten Seite eine in Längsrichtung des Spulenkörpers vorstehende Wand, die von den Sockeln einen vorbestimmten Abstand hat, welcher zum Hindurchführen des Wickeldrahtes oder der Wickeldrähte dient. Durch diese Maßnahmen wird für den oder die Wickeldrähte eine Führungsbahn geschaffen, die ein kreuzungsfreies Zuführen der Enden der Wickeldrähte zu den Stiften gewährleistet.According to an embodiment of the invention, the terminal block carries on the side facing the winding body a wall projecting in the longitudinal direction of the coil body, which has a predetermined distance from the bases, which is used to pass the winding wire or the winding wires. These measures create a guideway for the winding wire or wires, which ensures that the ends of the winding wires are fed to the pins without crossing.
Eine andere Ausführungsform der Erfindung sieht vor, daß die Wand einen vertikal abstehenden Abstandhalter trägt, dessen Ende die Höhe des am Stift angewickelten Wickeldrahtes übersteigt. Dieser Abstandhalter dient dazu, einen definierten Abstand zur Printplatte herzustellen, so daß das Ende des am Stift angewickelten und angelöteten Wickeldrahtes ausreichenden Abstand zu Durchgangslöchern in der Printplatte hat und Blindlötungen infolge abgedeckter Durchgangslöcher nicht entstehen können.Another embodiment of the invention provides that the wall carries a vertically projecting spacer, the end of which exceeds the height of the winding wire wound on the pin. This spacer is used to produce a defined distance from the printed circuit board, so that the end of the winding wire wound and soldered to the pin has a sufficient distance from through holes in the printed circuit board and blind soldering cannot occur as a result of covered through holes.

In Figur 1 ist ein Ausführungsbeispiel eines Spulenkörpers 10 nach der Erfindung perspektivisch dargestellt. Der Spulenkörper 10 hat einen Wickelkörper 12 mit einer durchgehenden Ausnehmung 14 für die Aufnahme eines zweischaligen Kerns 16, der im Bildteil oben dargestellt ist. Am Wickelkörper 12 sind an seinen Enden Flansche 16, 18 ausgebildet, welche Wicklungen (nicht dargestellt) auf dem Wickelkörper 12 randseitig begrenzen.In Figure 1, an embodiment of a
Am oberen Flansch 16 sind zwei Anschlußleisten 20, 22 angeordnet, welche mittig segmentartige Ausnehmungen 24 bzw. 26 haben. Die Anschlußleisten 20, 22 tragen Stifte 28, von denen zur besseren Übersicht lediglich einer mit dem Bezugszeichen 28 versehen ist. Die Stifte 28 sind auf beiden Anschlußleisten 20, 22 längs einer Geraden ausgerichtet und haben im wesentlichen eine zylindrische Form. Die Stifte 28 sind in Sockeln 30 eingebettet, von denen lediglich einer mit dem Bezugszeichen 30 versehen ist. In Richtung annähernd senkrecht zu der Längsachse der jeweiligen Anschlußleiste 20, 22 steht an jedem Sockel 30 ein Umlenkzapfen 32 senkrecht zur Achse des Stiftes 28 ab, der eine zylindrische Form hat. Jeder Sockel 30 hat nach oben zum Stift 28 eine Abrundung 34.On the
Jede Anschlußleiste 20, 22 trägt auf der dem Wickelkörper 12 zugewandten Seite eine in Längsrichtug des Spulenkörpers 10 vorstehende Wand 36, welche von den Sockeln 30 einen vorbestimmten Abstand hat. Dadurch wird eine Führungsbahn 38 geschaffen, welche zum Zuführen des jeweiligen Wicklungsdrahtes zu den Stiften 28 dient.Each
Jede Wand 36 trägt Abstandselemente 40, die einen definierten Abstand zu einer Printplatte (nicht dargestellt) einstellen. Die Höhe des jeweiligen Abstandselements 40 ist so ausgelegt, daß ein am Stift 28 angewickelter Wickeldraht sowie das zugehörige Lötzinn ausreichenden Abstand von der Printplatte hat und das Ende des Wickeldrahtes oder der Lötbatzen nicht das Durchgangsloch auf der Printplatte verstopfen, in die der Stift 28 eingesetzt ist. Fehllötungen werden somit verhindert.Each
Die beiden Flansche 16, 18 haben je eine Richtausnehmung 42 (lediglich die untere Richtausnehmung 42 ist zu erkennen) für einen Wickeldorn der Wickelmaschine. Diese Richtausnehmung legt somit die Lagebeziehung zwischen Spulenkörper 10 und Wickelmaschine fest.The two
Der im oberen Bildteil gezeigte zweischalige Kern 16 hat ein mittleres Säulenteil 44, welches in die Ausnehmung 14 des Wickelkörpers 12 paßt. Die äußere Form des Magnetkerns 16 ist derart, daß der obere und der untere Abschnitt 46 annähernd bündig an den Innenflächen der Anschlußleisten 20, 22 bzw. an Anschlagflächen 48 anliegen.The double-
Figur 2 zeigt schematisch den Verlauf eines Wickeldrahtes 50 vom Wickelkörper 12 zum Stift 28. Der Wickeldraht 50 wird durch die Ausnehmung 24 über die Führungsbahn 38 geführt und gelangt zwischen zwei Sockeln 30 nach vorne zum Umlenkzapfen 32, durch den er umgelenkt wird. Anschließend wird der Wickeldraht 50 zum Grund des Stiftes 28 geführt, wobei er auf der Abrundung 34 aufliegt. Danach wird der Wickeldraht 50 um den Stift 28 gewickelt. Durch die Umlenkung des Wickeldrahtes um den Umlenkzapfen 32 entsteht eine Zugentlastung, so daß auch bei straffer Wickeldrahtführung die Gefahr der Beschädigung oder des Abreißens verringert ist. Die Abrundung 34 ermöglicht eine Wickeldrahtführung ohne Verhaken des Wickeldrahtes 50.FIG. 2 schematically shows the course of a winding
Figur 3 zeigt eine Draufsicht auf den Spulenkörper 10 nach Figur 1, und läßt Teile, die in der Figur 1 verdeckt sind, besser erkennen. Gleiche Teile sind mit gleichen Bezugszeichen versehen.FIG. 3 shows a plan view of the coil former 10 according to FIG. 1, and makes it easier to see parts which are hidden in FIG. 1. The same parts are provided with the same reference numerals.
Die Stifte 28 der beiden Anschlußleisten liegen in Ebenen parallel zur Längsachse des Spulenkörpers 10 und zeigen in dieselbe Richtung. Dadurch ist es möglich, die angewickelten Enden der Wickeldrähte an allen Stiften 28 in einem einzigen Lötvorgang, z.B. durch Tauchlöten, zu verlöten.The
Es ist noch darauf hinzuweisen, daß die Stifte 28 vorzugsweise ein Paar abgeflachter Seitenflächen haben, so daß eine Zylinderform entsteht, die seitlich abgeflacht ist. Weiterhin hat die zylinderförmige Oberfläche eine Riffelung. Die im Übergangsbereich zwischen flacher Seitenfläche und Zylinderfläche entstehende Kante dient als Abrißkante für den angewickelten Wickeldraht. Weitere Einzelheiten über die Ausgestaltung der Stifte 28 sind im deutschen Gebrauchsmuster 295 12 324.9 beschrieben, deren Inhalt zum Offenbarungsgehalt der vorliegenden Anmeldung gehört.It should also be noted that the
