Definitions
- the invention relates to a bobbin with a continuous recess for receiving a core, with a winding body containing the recess, at both ends of which flanges are formed in the transverse plane to the longitudinal axis of the recess, with a connection strip being formed on at least one flange, the at least has four solder connections arranged side by side in a row for winding wires wound around the winding body.
- Such a coil former is known from DE 32 41 408 C2.
- solder connections for wrapping the ends of the winding wires soldering swords with an approximately rectangular flat cross section are used, the width of which is considerably greater than its height.
- the wrapped ends of the winding wires are connected to the soldering swords by soldering.
- length changes occur on the winding wire, which increase the tensile stress in the winding wire, whereby the soldering quality is impaired and damage or tearing of the winding wire can occur during operation under fluctuating working temperatures.
- the winding around a soldering sword with the winding wire in an automatic winding machine is complex, since guiding the winding wire from the winding chamber to the soldering sword is complicated. Due to the low height in the cross section of the respective soldering sword, the winding wire must be bent with a small radius of curvature, so that the winding wire can break or tear off at the edges of the soldering lugs if the winding wire is guided tightly.
- Another disadvantage of the known coil body is that the winding wires must have a relatively large diameter when the current is high. Due to the flat cross section, the soldering swords can be easily bent when wrapping with thick winding wires.
- solder connections are designed as essentially cylindrical pins which are embedded in spaced bases in a plane perpendicular to the longitudinal axis and in such a way that each base faces on the side facing the associated pin tapers, and that reinforcing ribs are formed on the side of the terminal block facing the recess.
- 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 or breaking on sharp edges.
- the cylindrical pins can be made relatively solid and have a diameter of 1 mm, for example. Accordingly, you can even thick winding wires can be wound around the pins under tight guidance without bending them.
- the pins are embedded in spaced-apart bases, which taper on the side facing the assigned pin.
- the side surface of the base tapering obliquely onto the pin means that the winding wire can be guided without snagging. You also gain height from the base of the terminal block through the base, which facilitates the soldering of the wrapped ends of the winding wires to the pins.
- the bases made of insulating material also serve to deflect the winding wires, so that there is a strain relief for the respective winding wire and the tensile stresses occurring during soldering due to the temperature differences are absorbed.
- reinforcing ribs are also formed on the side of the terminal block facing the recess. These reinforcing ribs increase the mechanical stability of the terminal block. Since this is connected in one piece to the associated flange, its mechanical stability and thus that of the entire coil body is also improved.
- the bases of the terminal block have a predetermined distance from the opposite side wall of the flange. Because of this distance, a guideway is created, which is used to pass the winding wire or wires. In addition, the winding wires are insulated from the core.
- the flange carries at least one spacer projecting vertically in the direction of the cylindrical pins, the end of which exceeds the height of the winding wire wound on the pin or the associated soldering mass.
- This spacer is used to create a defined distance from a printed circuit board, so that the end of the soldered winding wire wound on 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.
- the side wall of the flange facing the terminal block has recesses for the passage of the winding wire or the winding wires from the winding body. These openings create separating openings which enable the wires to pass through the winding body to the terminal block without crossing them.
- FIG 1 an embodiment of a bobbin 10 according to the invention is shown in perspective.
- the bobbin 10 is made from one piece of plastic, preferably of glass fiber reinforced polyamide. It has a continuous winding body 12 with a continuous recess 14 for receiving a core (not shown).
- Flanges 16, 18 are formed on the winding body 12 at its ends in a transverse plane.
- two center flanges are arranged in the middle of the winding body 12 in planes perpendicular to the longitudinal axis of the recess 14.
- the flanges 16, 18, 20, 22 axially delimit two winding chambers 24, 26 which accommodate windings (not shown).
- Terminal strips 28 and 30 are formed on the two outer flanges 16 and 18, respectively.
- the connection strips 28, 30 carry pins 32, of which only one is provided with the reference number 32 for a better overview.
- the pins 32 are aligned on both connecting strips 28, 30 along a straight line and have a substantially cylindrical shape.
- the pins 32 are embedded in bases 34, of which only one is provided with the reference number 34.
- the pins 32 of the terminal strips 28, 30 protrude vertically in a plane perpendicular to the longitudinal axis of the recess 14.
- Each base 34 has a square base surface and tapers in the direction of the pin 32.
- the side surfaces 36 of the base 34 are trapezoidal.
- the flanges 16, 18 have on the side opposite the terminal strips 28, 30 side walls 28, 40 at a distance from the bases 34. Due to the distance between the side walls 38, 40 there is a guideway for the winding wires.
- the side walls 38, 40 also have recesses 42, 44, which allow a defined, crossing-free passage of the winding wire or the winding wires from the winding chambers 24 and 26 to the terminal strips 28, 30 and the pins 32.
- Each flange 16, 18 has two spacers 46 projecting vertically in the direction parallel to the cylindrical pins 32, the ends of which exceed the respective height of the winding wires wound on the pins 32 or the associated soldering compounds.
- connection strips 28, 30 have reinforcing ribs 48 on their sides facing the recess 14, which increase their mechanical stability. Since, as mentioned, the coil body 10 is made in one piece, the overall mechanical stability of the coil body 10 is improved by the reinforcing ribs 48.
- FIG. 2 shows the bobbin 10 according to FIG. 1 with a wound winding wire 50.
- the winding wire 50 is fed from the winding chamber 24 via one of the separating openings 42 in the side wall 38 and deflected by two bases 34; then one end of the winding wire 50 is wrapped around the pin 32. Because of the sloping side surfaces 36, the wire 50 cannot get caught even during automatic winding. By deflecting the winding wire 50 around the two bases 34, strain relief is possible which absorbs the tensile stresses due to the temperature change during soldering.
- FIG. 3 shows in a schematic side view (the central flanges 20, 22 have been omitted) how the height of the spacers 46 is dimensioned.
- the ends 52 of the spacers 46 protrude beyond the soldering mass 54 of a wrapped pin 32.
- the spacers 46 therefore produce a defined distance from a printed circuit board (not shown) arranged on the pin side.
- the height of the respective spacer 46 is designed so that a winding wire 50 wound on the pin 32 and the associated solder 54 have a sufficient distance from the printed circuit board and the end of the winding wire 50 or the soldering mass 54 does not clog the through hole on the printed circuit board into which the Pin 32 is inserted. This prevents incorrect soldering.
- the pins 32 of both connecting strips 28, 30 run in planes parallel to the flanges 16, 18 and point in the same direction. This makes it possible to remove the wound ends from Winding wires 50 to all pins 32 in a single soldering process, for example 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.

Abstract
Description
Die Erfindung betrifft einen Spulenkörper mit einer durchgehenden Ausnehmung für die Aufnahme eines Kerns, mit einem die Ausnehmung enthaltenden Wickelkörper, an dessen beiden Enden in der Querebene zur Längsachse der Ausnehmung verlaufende Flansche ausgebildet sind, wobei an mindestens einem Flansch eine Anschlußleiste angeformt ist, die mindestens vier nebeneinander in einer Reihe angeordnete Lötanschlüsse für um den Wickelkörper gewickelte Wickeldrähte hat.The invention relates to a bobbin with a continuous recess for receiving a core, with a winding body containing the recess, at both ends of which flanges are formed in the transverse plane to the longitudinal axis of the recess, with a connection strip being formed on at least one flange, the at least has four solder connections arranged side by side in a row for winding wires wound around the winding body.
Ein derartiger Spulenkörper ist aus der DE 32 41 408 C2 bekannt. Als Lötanschlüsse für die Umwicklung der Enden der Wickeldrähte werden Lötschwerter mit annähernd rechteckförmigem flachen Querschnitt verwendet, dessen Breite erheblich größer ist als seine Höhe. Die umwickelten Enden der Wickeldrähte werden mit den Lötschwertern durch Löten verbunden. Bei diesem Lötvorgang treten infolge der hohen Löttemperatur und dem nachfolgenden Abkühlen Längenänderungen am 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 eines Lötschwertes mit dem Wickeldraht in einer automatischen Wickelmaschine aufwendig, da die Führung des Wickeldrahtes von der Wickelkammer zum Lötschwert kompliziert ist. Aufgrund der geringen Höhe im Querschnitt des jeweiligen Lötschwertes, muß der Wickeldraht mit kleinem Krümmungsradius gebogen werden, so daß bei straffer Wickeldrahtführung der Wickeldraht an den Kanten der Lötfahnen brechen oder abreißen kann. Ein weiterer Nachteil des bekannten Spulenkörpers liegt darin, daß bei hoher Strombelastung der Wickeldrähte diese einen relativ großen Durchmesser haben müssen. Aufgrund des flachen Querschnittes können die Lötschwerter beim Umwickeln mit dicken Wickeldrähten leicht verbogen werden.Such a coil former is known from DE 32 41 408 C2. As solder connections for wrapping the ends of the winding wires, soldering swords with an approximately rectangular flat cross section are used, the width of which is considerably greater than its height. The wrapped ends of the winding wires are connected to the soldering swords by soldering. During this soldering process, due to the high soldering temperature and the subsequent cooling, length changes occur on the winding wire, which increase the tensile stress in the winding wire, whereby 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 winding around a soldering sword with the winding wire in an automatic winding machine is complex, since guiding the winding wire from the winding chamber to the soldering sword is complicated. Due to the low height in the cross section of the respective soldering sword, the winding wire must be bent with a small radius of curvature, so that the winding wire can break or tear off at the edges of the soldering lugs if the winding wire is guided tightly. Another disadvantage of the known coil body is that the winding wires must have a relatively large diameter when the current is high. Due to the flat cross section, the soldering swords can be easily bent when wrapping with thick winding wires.
Es ist Aufgabe der Erfindung, einen Spulenkörper anzugeben, der einen stabilen Aufbau hat, ein einfaches automatisches Wickeln gestattet und der betriebssicher arbeitet.It is an object of the invention to provide a bobbin that has a stable structure, allows simple automatic winding and works reliably.
Diese Aufgabe wird für einen Spulenkörper eingangs genannter Art dadurch gelöst, daß die Lötanschlüsse als im wesentlichen zylindrische Stifte ausgebildet sind, die in einer Ebene senkrecht zur Längsachse vertikal abstehend in voneinander beabstandeten Sockeln eingebettet sind, daß jeder Sockel sich auf der dem zugeordneten Stift zugewandten Seite verjüngt, und daß auf der der Ausnehmung zugewandten Seite der Anschlußleiste Verstärkungsrippen ausgebildet sind.This object is achieved for a coil former of the type mentioned above in that the solder connections are designed as essentially cylindrical pins which are embedded in spaced bases in a plane perpendicular to the longitudinal axis and in such a way that each base faces on the side facing the associated pin tapers, and that reinforcing ribs are formed on the side of the terminal block facing the recess.
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 oder Brechens des Wickeldrahtes an scharfen Kanten entsteht. Die zylindrischen Stifte können relativ massiv ausgeführt sein und beispielsweise einen Durchmesser von 1 mm haben. Demgemäß können auch dicke Wickeldrähte unter straffer Führung um die Stifte gewickelt werden, ohne diese zu verbiegen.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 or breaking on sharp edges. The cylindrical pins can be made relatively solid and have a diameter of 1 mm, for example. Accordingly, you can even thick winding wires can be wound around the pins under tight guidance without bending them.
Die Stifte sind in voneinander beabstandeten Sockeln eingebettet, die sich auf der dem zugeordneten Stift zugewandten Seite verjüngen. Die auf den Stift schräg zulaufende Seitenfläche der Sockel bewirkt, daß ein Führen des Wickeldrahtes ohne Verhaken möglich ist. Außerdem gewinnt man durch den Sockel Höhe von der Grundfläche der Anschlußleiste, wodurch das Verlöten der umwickelten Enden der Wickeldrähte mit den Stiften erleichtert wird. Die Sockel aus Isoliermaterial dienen ferner zur Umlenkung der Wickeldrähte, so daß eine Zugentlastung für den jeweiligen Wickeldraht entsteht und die beim Löten aufgrund der Temperaturunterschiede auftretenden Zugspannungen abgefangen werden.The pins are embedded in spaced-apart bases, which taper on the side facing the assigned pin. The side surface of the base tapering obliquely onto the pin means that the winding wire can be guided without snagging. You also gain height from the base of the terminal block through the base, which facilitates the soldering of the wrapped ends of the winding wires to the pins. The bases made of insulating material also serve to deflect the winding wires, so that there is a strain relief for the respective winding wire and the tensile stresses occurring during soldering due to the temperature differences are absorbed.
Erfindungsgemäß sind weiterhin auf der der Ausnehmung zugewandten Seite der Anschlußleiste Verstärkungsrippen ausgebildet. Diese Verstärkungsrippen erhöhen die mechanische Stabilität der Anschlußleiste. Da diese einstückig mit dem zugehörigen Flansch verbunden ist, wird auch dessen mechanische Stabilität und damit die des gesamten Spulenkörpers verbessert.According to the invention, reinforcing ribs are also formed on the side of the terminal block facing the recess. These reinforcing ribs increase the mechanical stability of the terminal block. Since this is connected in one piece to the associated flange, its mechanical stability and thus that of the entire coil body is also improved.
Aufgrund der übersichtlichen Anordnung der Stifte und des Wickelkörpers sowie ihre rechtwinklige Lage zueinander, ist es möglich, sämtliche Wickeldrähte in einer automatischen Wickelmaschine von der Wickelkammer bis zum Stift einfach zu führen.Due to the clear arrangement of the pins and the winding body and their right-angled position to each other, it is possible to easily guide all winding wires in an automatic winding machine from the winding chamber to the pin.
Bei einer bevorzugten Ausführungsform der Erfindung haben die Sockel der Anschlußleiste einen vorbestimmten Abstand von der gegenüberliegenden Seitenwand des Flansches. Aufgrund dieses Abstandes wird eine Führungsbahn geschaffen, welche zum Hindurchführen des Wickeldrahtes oder der Wickeldrähte dient. Außerdem sind dadurch die Wickeldrähte isoliert vom Kern abgedeckt.In a preferred embodiment of the invention, the bases of the terminal block have a predetermined distance from the opposite side wall of the flange. Because of this distance, a guideway is created, which is used to pass the winding wire or wires. In addition, the winding wires are insulated from the core.
Gemäß einer Weiterbildung der Erfindung trägt der Flansch mindestens einen in Richtung der zylindrischen Stifte vertikal abstehenden Abstandhalter, dessen Ende die Höhe des am Stift angewickelten Wickeldrahtes bzw. der zugehörigen Lötmasse übersteigt. Dieser Abstandhalter dient dazu, einen definierten Abstand zu einer Printplatte herzustellen, so daß das Ende des am Stift angewickelten angelöteten Wickeldrahtes ausreichenden Abstand zu Durchgangslöchern in der Printplatte hat und Blindlötungen infolge abgedeckter Durchgangslöcher nicht entstehen können.According to a development of the invention, the flange carries at least one spacer projecting vertically in the direction of the cylindrical pins, the end of which exceeds the height of the winding wire wound on the pin or the associated soldering mass. This spacer is used to create a defined distance from a printed circuit board, so that the end of the soldered winding wire wound on 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.
Gemäß einer anderen Weiterbildung hat die der Anschlußleiste zugewandte Seitenwand des Flansches Ausnehmungen für das Hindurchführen des Wickeldrahtes oder der Wickeldrähte vom Wickelkörper. Durch diese Ausnehmungen werden Trennöffnungen geschaffen, die ein kreuzungsfreies Hindurchtreten der Drähte vom Wickelkörper zur Anschlußleiste ermöglichen.According to another development, the side wall of the flange facing the terminal block has recesses for the passage of the winding wire or the winding wires from the winding body. These openings create separating openings which enable the wires to pass through the winding body to the terminal block without crossing them.

In Figur 1 ist ein Ausführungsbeispiel eines Spulenkörpers 10 nach der Erfindung perspektivisch dargestellt. Der Spulenkörper 10 ist aus einem Stück aus Kunststoff hergestellt, vorzugsweise aus glasfaserverstärktem Polyamid. Er hat einen durchgehenden Wickelkörper 12 mit einer durchgehenden Ausnehmung 14 für die Aufnahme eines Kerns (nicht dargestellt). Am Wickelkörper 12 sind an seinen Enden in einer Querebene verlaufende Flansche 16, 18 ausgebildet. Auf dem Wickelkörper 12 sind ferner mittig zwei Mittelflansche in Ebenen senkrecht zur Längsachse der Ausnehmung 14 angeordnet. Die Flansche 16, 18, 20, 22 begrenzen axial zwei Wickelkammern 24, 26, welche Wicklungen (nicht dargestellt) aufnehmen.In Figure 1, an embodiment of a
An den beiden äußeren Flanschen 16 bzw. 18 sind Anschlußleisten 28 bzw. 30 angeformt. Die Anschlußleisten 28, 30 tragen Stifte 32, von denen zur besseren Übersicht lediglich einer mit dem Bezugszeichen 32 versehen ist. Die Stifte 32 sind auf beiden Anschlußleisten 28, 30 längs einer Geraden ausgerichtet und haben im wesentlichen eine zylindrische Form. Die Stifte 32 sind in Sockeln 34 eingebettet, von denen lediglich einer mit dem Bezugszeichen 34 versehen ist. Die Stifte 32 der Anschlußleisten 28, 30 stehen in einer Ebene senkrecht zur Längsachse der Ausnehmung 14 vertikal ab. Jeder Sockel 34 hat eine quadratische Basisfläche und verjüngt sich in Richtung des Stiftes 32. Die Seitenflächen 36 der Sockel 34 sind trapezförmig.
Die Flansche 16, 18 haben auf der den Anschlußleisten 28, 30 gegenüberliegenden Seite Seitenwände 28, 40 im Abstand von den Sockeln 34. Aufgrund des Abstandes ergibt sich zwischen den Seitenwänden 38, 40 eine Führungsbahn für die Wickeldrähte. Die Seitenwände 38, 40 haben ferner Ausnehmungen 42, 44, die ein definiertes, kreuzungsfreies Hindurchführen des Wickeldrahtes oder der Wickeldrähte von den Wickelkammern 24 bzw. 26 zu den Anschlußleisten 28, 30 und den Stiften 32 ermöglicht.The
Jeder Flansch 16, 18 hat zwei in Richtung parallel zu den zylindrischen Stiften 32 vertikal abstehende Abstandhalter 46, deren Enden die jeweilige Höhe der an den Stiften 32 angewickelten Wickeldrähte bzw. der zugehörigen Lötmassen übersteigt.Each
Die Anschlußleisten 28, 30 haben auf ihren der Ausnehmung 14 zugewandten Seiten Verstärkungsrippen 48, welche ihre mechanische Stabilität erhöhen. Da wie erwähnt der Spulenkörper 10 aus einem Stück hergestellt ist, wird durch die Verstärkungsrippen 48 die gesamte mechanische Stabilität des Spulenkörpers 10 verbessert.The
Figur 2 zeigt den Spulenkörper 10 nach Figur 1 mit einem angewickelten Wickeldraht 50. Der Wickeldraht 50 wird von der Wickelkammer 24 über eine der Trennöffnungen 42 in der Seitenwand 38 zugeführt und durch zwei Sockel 34 umgelenkt; sodann ist ein Ende des Wickeldrahtes 50 um den Stift 32 umgewickelt. Aufgrund der schräg zulaufenden Seitenflächen 36 ist ein Verhaken des Drahtes 50 auch beim automatischen Wickeln ausgeschlossen. Durch die Umlenkung des Wickeldrahtes 50 um die beiden Sockel 34 wird eine Zugentlastung möglich, die die Zugspannungen infolge der Temperaturänderung beim Löten abfängt.FIG. 2 shows the
In Figur 3 ist in einer schematischen Seitenansicht (die Mittelflansche 20, 22 wurden weggelassen) zu erkennen, wie die Höhe der Abstandshalter 46 bemessen ist. Die Enden 52 der Abstandshalter 46 überragen die Lötmasse 54 eines umwickelten Stiftes 32. Die Abstandshalter 46 stellen also einen definierten Abstand zu einer stiftseitig angeordneten Printplatte (nicht dargestellt) her. Die Höhe des jeweiligen Abstandshalters 46 ist so ausgelegt, daß ein am Stift 32 angewickelter Wickeldraht 50 sowie das zugehörige Lötzinn 54 ausreichenden Abstand von der Printplatte hat und das Ende des Wickeldrahtes 50 oder der Lötmasse 54 nicht das Durchgangsloch auf der Printplatte verstopfen, in die der Stift 32 eingesetzt ist. Fehllötungen werden somit verhindert.FIG. 3 shows in a schematic side view (the
Die Stifte 32 beider Anschlußleisten 28, 30 verlaufen in Ebenen parallel zu den Flanschen 16, 18 und zeigen in dieselbe Richtung. Dadurch ist es möglich, die angewickelten Enden von Wickeldrähten 50 an allen Stiften 32 in einen 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.It should also be noted that the
