Die Erfindung betrifft eine Spule, eine Bremse und einen Elektromotor.The invention relates to a coil, a brake and an electric motor.
Spulenträger für mit Wicklungsdraht bewickelte Spulen sind allgemein bekannt.Coil carriers for coils wound with winding wire are generally known.
Aus der DE 36 13 294 ist eine Bremsspule mit einem Mittelabgriff (Fig. 4, Bezugszeichen 6) bekannt, die als Bremse für einen Elektromotor verwendbar ist. Nachteilig ist dabei, dass die Fertigung aufwendig und kostspielig ist. Dabei ist wichtig, dass jeder zusätzliche Kontakt des Wicklungsdrahtes beim Herstellen Aufwand und Kosten verursacht.From DE 36 13 294 a brake coil with a center tap (Fig. 4, reference numeral 6) is known, which can be used as a brake for an electric motor. The disadvantage here is that the production is complex and expensive. It is important that every additional contact of the winding wire causes effort and costs during the manufacture.
Aus der DE 79 23 585 U1 ist ein Verbinden von Draht bekannt, wobei der Wicklungsdraht der Spule um das stiftförmige Ende mehrfach herumgewickelt werden mussFrom DE 79 23 585 U1 a connection of wire is known, the winding wire of the coil having to be wound several times around the pin-shaped end
(„herumschlingen" Seite 4, 3. Absatz, Zeile 4 - 5)und dann angelötet werden muss. Dies ist sehr aufwendig und kostspielig.("Loop around" page 4, 3rd paragraph, lines 4 - 5) and then have to be soldered on. This is very complex and costly.
Aus der DE 34 07 758 A1 ist ein Haken an einem Anschlussstück bekannt, der zum Sichern gegen das Herausziehen vorgesehen ist (E2, Seite 9, Zeile 11). Nachteilig ist wiederum, dass das Verbinden des Wicklungsdrahtes sehr aufwendig und kompliziert ist.DE 34 07 758 A1 discloses a hook on a connecting piece which is provided for securing against being pulled out (E2, page 9, line 11). Another disadvantage is that the connection of the winding wire is very complex and complicated.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Spule weiterzubilden, um sie kostengünstiger und einfacher zu fertigen, insbesondere samt Kontaktierung. Dies betrifft besonders auch Spulen mit mehreren Abgriffen, insbesondere mindestens einem Mittelabgriff.The invention is therefore based on the object of developing a coil in order to manufacture it more cost-effectively and easily, in particular including contacting. This particularly applies to coils with multiple taps, in particular at least one center tap.
Erfindungsgemäß wird die Aufgabe bei der Spule nach den in Anspruch 1 oder 2 und bei der Bremse nach den in Anspruch 16 und bei dem Elektromotor nach den in Anspruch 17 angegebenen Merkmalen gelöst. Wesentliche Merkmale der Erfindung bei der Spule sind, dass sie zumindest einen Spulenträger und einem Wicklungsdraht umfasst, insbesondere einem zur elektrischen Isolierung lackierten Wicklungsdraht,According to the invention the object is achieved in the coil according to the claims 1 or 2 and in the brake according to the claims 16 and in the electric motor according to the features specified in claim 17. Essential features of the invention in the coil are that it comprises at least one coil carrier and a winding wire, in particular a winding wire coated for electrical insulation,
wobei der Spulenträger zumindest einen Kanal umfasst, insbesondere einen als Tasche ausgebildeten,wherein the coil carrier comprises at least one channel, in particular a pocket-shaped
wobei mindestens eine Hülse mit dem Wicklungsdraht elektrisch verbunden ist,wherein at least one sleeve is electrically connected to the winding wire,
wobei die Hülse mit einer elektrischen Leitung, insbesondere Litze eines Kabels, elektrisch verbunden ist,the sleeve being electrically connected to an electrical line, in particular a strand of a cable,
wobei die Hülse verformbare Bereiche umfasst,the sleeve comprising deformable areas,
wobei zur Herstellung der elektrischen Verbindungen ein jeweiliger verformbarer Bereich derart verformbar ist, dass eine kraftschlüssige Verbindung vorgesehen ist und ein Verschweißen ausführbar ist.a respective deformable region being deformable in such a way that a non-positive connection is provided and welding can be carried out in order to produce the electrical connections.
Von Vorteil ist dabei, dass die Hülse eine kostengünstige elektrische Verbindungsart ermöglicht. Insbesondere ist die Hülse selbst als kostengünstiges Stanz-Biegeteil aus Blech herstellbar. Da sie verformbare Bereiche aufweist, sind mittels dieser Bereiche Wicklungsdraht-Abschnitte oder Litzen-Abschnitte einklemmbar, also kraftschlüssig verbindbar. Durch entsprechendes Erhitzen sind dann Schweißverbindungen herstellbar. Mittels weiterer verformbarer Bereiche sind auch andere Teile des Kabels einklemmbar und somit eine Zugentlastung für das Kabel mit Litze realisierbar.The advantage here is that the sleeve enables an inexpensive type of electrical connection. In particular, the sleeve itself can be produced from sheet metal as an inexpensive stamped and bent part. Since it has deformable regions, winding wire sections or stranded sections can be clamped in by means of these regions, that is to say they can be connected in a force-locking manner. Welding connections can then be produced by appropriate heating. By means of further deformable areas, other parts of the cable can also be clamped in, and thus a strain relief for the cable with a strand can be realized.

Die Schweißverbindung ist gut geschützt gegen belastende Kräfte, weil die kraftschlüssige Verbindung weiterwirkt und somit die Schweißverbindung entlastet.In particular, the sleeve comprises at least one first support area, which is provided as a support and / or guide for the winding wire, the sleeve comprising at least a second area, designed as a tongue, which is deformable for non-positive connection to the winding wire and for It is possible to provide a welded connection with the winding wire, the sleeve comprising at least a third area, in particular a partial wall area, which is provided for the welded connection to the strand of a cable.

Die Erfindung wird nun anhand von Abbildungen näher erläutert:The invention will now be explained in more detail with reference to figures:
In der Figur 1 ist ein Spulenträger 2 gezeigt. Er ist vorteiligerweise als Kunststoff- Spritzgussteil fertigbar und weist eine Halterung 7 auf als Befestigung für ein abgehendes Kabel.A coil carrier 2 is shown in FIG. It can advantageously be manufactured as a plastic injection molded part and has a holder 7 as a fastening for an outgoing cable.
In der Figur 2 sind drei Hülsen 1 gezeigt, die an drei Stellen am Umfang in den Spulenträger einführbar sind.In FIG. 2, three sleeves 1 are shown, which can be inserted into the coil carrier at three locations on the circumference.
Den genaueren Aufbau der Hülsen 1 zeigen die Figuren 12 und 13.FIGS. 12 and 13 show the more precise structure of the sleeves 1.
In der Figur 3 ist ein Kabel 3, umfassend elektrisch leitfähige Litze und Isolierung, gezeigt, das in den unteren Teil der Hülse 1 einführbar ist, bevor diese in den Spulenträger einsteckbar sind.FIG. 3 shows a cable 3, comprising electrically conductive strands and insulation, which can be inserted into the lower part of the sleeve 1 before it can be inserted into the coil carrier.
In der Figur 4 sind die drei Kabel 3 gezeigt, welche mit entsprechenden Hülsen 1 verbunden sind, bevor sie in den Spulenträger 1 eingeführt werden.FIG. 4 shows the three cables 3 which are connected to corresponding sleeves 1 before they are inserted into the coil carrier 1.
Figur 5 zeigt das mit der Hülse 1 verbundene Kabel 3 vergrößert, wobei Figur 12 die Hülse 1 selbst ohne Kabel vergrößert darstellt. Das linke Biegeteil 25 ist derart verformt, dass die Isolierung der Hülse 1 fixiert ist und somit eine Zugentlastung für den rechten Teil des Kabels vorgesehen ist. Das rechte Biegeteil 20 ist mit der Litze des Kabels 3 elektrisch leitfähig verbunden, insbesondere verschweißt.FIG. 5 shows the cable 3 connected to the sleeve 1 on an enlarged scale, FIG. 12 showing the sleeve 1 enlarged even without a cable. The left bending part 25 is deformed in such a way that the insulation of the sleeve 1 is fixed and thus strain relief is provided for the right part of the cable. The right bending part 20 is electrically conductively connected, in particular welded, to the strand of the cable 3.
Figur 6 zeigt den Spulenträger 2, wobei die mit den Kabeln verbundenen Hülsen 1 eingeführt sind.Figure 6 shows the bobbin 2, with the sleeves 1 connected to the cables being inserted.
Figur 7 zeigt den Kanal 4, in welchen die Hülsen 1 eingeschoben sind, deutlicher. Der Kanal 4 ist als Tasche ausgeführt. Figur 8 zeigt wie Figur 7 die eingeschobenen Hülsen, wobei die Kabel durch die Öse der Halterung 7 geführt sind. Figur 9 zeigt eine Halterung 6 zur Fixierung eines ersten Endes eines Wicklungsdrahtes 5, welcher über die Hülse 1 geführt wird und auf den Zungen 24 der Hülse 1 aufliegt, wobei Figur 12 die Hülse 1 selbst ohne Kabel vergrößert darstellt.Figure 7 shows the channel 4, in which the sleeves 1 are inserted, more clearly. Channel 4 is designed as a pocket. FIG. 8 shows, like FIG. 7, the inserted sleeves, the cables being led through the eyelet of the holder 7. FIG. 9 shows a holder 6 for fixing a first end of a winding wire 5 which is guided over the sleeve 1 and rests on the tongues 24 of the sleeve 1, FIG. 12 showing the sleeve 1 enlarged even without a cable.
Figur 10 zeigt einen über die Hülse 1 geführten Wicklungsdraht 5.FIG. 10 shows a winding wire 5 guided over the sleeve 1.
Figur 11 zeigt die Hülse 1 im in den Spulenträger eingeschobenen Zustand.Figure 11 shows the sleeve 1 in the inserted state in the coil carrier.
In der Figur 12 ist die Hülse größer gezeigt als in Figur 13a. Die Hülse ist als Stanz-Biegeteil ausgeführt und weist eine Wandteil 23 auf, an dem eine Zunge 22, weggebogen ist.The sleeve is shown larger in FIG. 12 than in FIG. 13a. The sleeve is designed as a stamped and bent part and has a wall part 23 on which a tongue 22 is bent away.
Bereiche mit Widerhaken 21 und weiteren Zungen 24 sind rechts und links angeordnet und sind ebenfalls weggebogen. Am unteren Ende des Wandteils 23 sind eine rechte Zunge 20 und eine linke Zunge 25 angeordnet und wiederum weggebogen.Areas with barbs 21 and other tongues 24 are arranged on the right and left and are also bent away. At the lower end of the wall part 23, a right tongue 20 and a left tongue 25 are arranged and in turn bent away.
In der Figur 13 b ist gezeigt, wie der Biegezustand der Zungen 20,25 ist, wenn ein Kabel mit seiner Isolierung von links kommend eingeführt ist und die Isolierung mit der linken Zunge 25 fixiert ist. Diese Fixierung bewirkt eine Zugentlastung für den abisolierten rechten Endteil des Kabels, also blanke Litze. Dieses Litzenstück wird mit der Zunge 20 zusammengedrückt und dann elektrisch verschweißt. Somit ist eine elektrisch sehr gut leitfähige Verbindung der Litze mit der Hülse geschaffen, die wegen der Zugentlastung hohe mechanische Belastungen erträgt.FIG. 13 b shows how the bent state of the tongues 20, 25 is when a cable with its insulation coming in from the left is inserted and the insulation is fixed with the left tongue 25. This fixation provides strain relief for the stripped right end part of the cable, i.e. bare wire. This strand of wire is pressed together with the tongue 20 and then electrically welded. This creates an electrically highly conductive connection of the stranded wire to the sleeve, which can withstand high mechanical loads due to the strain relief.
In der Figur 13c ist der Biegezustand der Zunge 22 gezeigt, die den Wicklungsdraht fixiert und mit welcher der Wicklungsdraht verschweißt wird.FIG. 13c shows the bent state of the tongue 22, which fixes the winding wire and with which the winding wire is welded.
Figur 13d zeigt im Unterschied zu Figur 13b die Kabelzuführung von rechts, wobei somit die Zunge 20 weniger verbogen ist zur Fixierung des Kabels mit Isolierung und die Zunge 25 stärker verbogen ist zur Fixierung der Litze des abisolierten Kabelendstückes.In contrast to FIG. 13b, FIG. 13d shows the cable feed from the right, the tongue 20 thus being less bent for fixing the cable with insulation and the tongue 25 being more bent for fixing the wire of the stripped cable end piece.
Figur 14a und 14 b zeigen den Spulenträger 2 in verschiedenen Orientierungen, wobei der als Tasche ausgeführte Kanal 4 gezeigt ist und auch der Schlitz 9 zum Einführen des Wicklungsdrahtes gezeigt ist. Der Wicklungsdraht wird dann bewickelt und am Ende über ein Eck und die Hülse 1 an die Halterung 6 geführt, wie in Figur 9 deutlich gezeigt ist. In weiteren erfindungsgemäßen Ausführungsbeispielen kann die Halterung 6 auch am Spulenträger weggelassen werden und stattdessen am Werkzeug vorgesehen werden.FIGS. 14a and 14b show the coil carrier 2 in different orientations, the channel 4 designed as a pocket being shown and also the slot 9 for introducing the winding wire being shown. The winding wire is then wound and, at the end, passed over a corner and the sleeve 1 to the holder 6, as is clearly shown in FIG. 9. In further exemplary embodiments according to the invention, the holder 6 on the coil carrier can also be omitted and can instead be provided on the tool.
In weiteren erfindungsgemäßen Ausführungsbeispielen wird der Kanal am Ende der Herstellung mit einer Vergussmasse vergossen. Somit ist ein mechanischer und auch chemischer Schutz erreichbar für die Spulenwicklung.In further exemplary embodiments according to the invention, the channel is cast with a casting compound at the end of production. Mechanical and chemical protection can thus be achieved for the coil winding.
Die Spule ist insbesondere vorteilhaft als Bremsspule einer elektromagnetisch betätigbaren Bremse vorsehbar. Diese Bremse kann vorteiligerweise in einem Elektromotor eingesetzt und integriert vorgesehen werden.The coil is particularly advantageously provided as a brake coil of an electromagnetically actuated brake. This brake can advantageously be used in an electric motor and can be provided integrated.
