In Sternschaltung betriebene Drehstrommotoren haben im Vergleich zu der Leiterspannung niedrige Strangspannungen, während der Strangstrom so groß wie der Leiterstrom ist. Wenn derartige Drehstrommotoren als leistungsfähige Antriebsmotoren z. B. in Kraftfahrzeugen eingesetzt werden, so sind hierfür eine Vielzahl von Leitungsdrähten in den einzelnen Spulen erforderlich. Die Verbindung der zu einem großen Bündel zusammengefaßten Leiter enden zu einem Sternpunkt ist sehr aufwendig und umständlich.Three-phase motors operated in star connection have a comparison low phase voltages to the conductor voltage during the Phase current is as large as the phase current. If such Three-phase motors as powerful drive motors e.g. B. in Motor vehicles are used, there are a large number for this of lead wires required in the individual coils. The Connection of the conductors combined into a large bundle ends at a star point is very complex and cumbersome.
Der Erfindung liegt die Aufgabe zugrunde, eine einfache und kostengünstigere Schaltverbindung parallel gewickelter Schalt drähte einer Sternschaltung in Drehstrommotoren zu schaffen. Diese Aufgabe wird durch die im Patentanspruch 1 gekennzeichnete Erfindung gelöst.The invention has for its object a simple and less expensive switching connection parallel-wound switching to create wires of a star connection in three-phase motors. This object is characterized by that in claim 1 Invention solved.
Die erfindungsgemäße Schaltverbindung ermöglicht eine einfachere Realisierung der Sternpunktverbindung von vielen Leitungsdrähten in Drehstrommotoren.The switching connection according to the invention enables a simpler one Realization of the star point connection of many lead wires in three-phase motors.
Weitere vorteilhafte Ausgestaltungen des Erfindungsgegenstandes sind den weiteren Unteransprüchen zu entnehmen. Es zeigen:Further advantageous refinements of the subject matter of the invention can be found in the further subclaims. Show it:

Die Fig. 1 zeigt einen Stator 1 eines Drehstrommotors mit einem Statorblechpaket 3 über dessen beide Stirnflächen 5, 7 Wicklungs köpfe 9, 11 von Statorspulen hinausragen. Die Fig. 1 zeigt ins besondere eine Schaltverbindung parallel gewickelter Schaltdrähte 13 zu einem Sternpunkt einer Sternschaltung in Drehstrommotoren. Die freien Spulenenden 15 sind zu kleineren Bündeln zusammenge faßt und über je ein Verbindungsglied mit einem einen Trenn schlitz aufweisenden Schaltring 17 elektrisch leitend verbunden. Der Schaltring 17 ist in einem Träger 19 gelagert, welcher aus einem Isolierwerkstoff hergestellt ist. Dieser Träger 19 ist auf den gegenüber der Stirnfläche 5 des Statorblechpaketes 3 vor stehenden Wicklungsköpfen 9 fest angeordnet. Im Rahmen der Erfindung kann der Träger 19 auch um die Wicklungsköpfe 9 herum gelegt und mit diesen Wicklungsköpfen 9 fest verbunden werden. Die Verbindungsglieder, von denen in der Fig. 1 sechs darge stellt sind, bestehen aus mit den freien Spulenenden 15 verbun denen Litzen 21, deren abisolierte freie Enden 23 mit dem Schalt ring 17 fest verbunden sind. Der Schaltring 17 ist ein Kupfer ring, der insbesondere einen runden Querschnitt aufweist. Fig. 1 shows a stator 1 of a three-phase motor with a stator core 3 over the two end faces 5 , 7 winding heads 9 , 11 protrude from stator coils. Fig. 1 shows in particular a switching connection wound parallel jumper wires 13 to a star point of a star connection three-phase motors. The free coil ends 15 are summarized in smaller bundles and electrically connected via a connector with a separating slot having a switching ring 17 . The switching ring 17 is mounted in a carrier 19 which is made of an insulating material. This carrier 19 is fixed on the opposite end face 5 of the stator core 3 in front of standing winding heads 9 . In the context of the invention, the carrier 19 can also be placed around the winding heads 9 and firmly connected to these winding heads 9 . The connecting links, of which six are shown in Fig. 1 Darge, consist of the free coil ends 15 verbun those strands 21 , the stripped free ends 23 with the switching ring 17 are fixedly connected. The switching ring 17 is a copper ring, which in particular has a round cross section.
Der Träger 19 besteht aus einem Hohlzylinderring 25 mit einem axial nach außen offenen, U-förmigen Ringkanal 27 zum Einlegen des Schaltringes 17, siehe Fig. 2. Die Außenwand 29 dieses U-förmigen Ringkanals 27 weist Ausnehmungen 31 zum Verbinden der abisolierten Enden 23 der Litze 21 mit dem Schaltring 17 auf. Eine definierte Lage der Litzen 21 wird dadurch erreicht, daß an der Außenseite 33 der zylindermantelförmigen Außenwand 29 des U-förmigen Ringkanals 27 Befestigungsglieder für die Litzen 21 angeordnet sind. Diese Befestigungsglieder bestehen aus an der Außenwand 29 angeordneten, radial nach außen gerichteten Halte stegen 35 mit an deren freien Enden parallel zur Motorachse ange ordneten Haltezungen 37. Diese Haltezungen 37 weisen zur Außen wand 33 in vorstehende Rastnasen 39 derart auf, daß die Litzen 21 beim Einschieben in den Zwischenraum zwischen den Haltezungen 37 und der Außenwand 33 sicher verrasten.The carrier 19 consists of a hollow cylindrical ring 25 with an axially outwardly open, U-shaped ring channel 27 for inserting the switching ring 17 , see FIG. 2. The outer wall 29 of this U-shaped ring channel 27 has recesses 31 for connecting the stripped ends 23 of the Strand 21 with the switching ring 17 . A defined position of the strands 21 is achieved in that fastening members for the strands 21 are arranged on the outer side 33 of the cylindrical jacket-shaped outer wall 29 of the U-shaped annular channel 27 . These fasteners consist of arranged on the outer wall 29 , radially outward holding webs 35 with at their free ends parallel to the motor axis arranged holding tongues 37th These holding tongues 37 have the outer wall 33 in protruding locking lugs 39 in such a way that the strands 21 lock securely when inserted into the space between the holding tongues 37 and the outer wall 33 .
In vorteilhafter Ausgestaltung kann der U-förmige Ringkanal 27 an seinen parallelen Schenkelflächen 41, 43 warzenförmige Erhebungen 45, 47 aufweisen, hinter denen der Schaltring 17 nach dessen Einlegen in den U-förmigen Ringkanal 27 verrastbar ist.In an advantageous embodiment, the U-shaped annular channel 27 can have wart-shaped elevations 45 , 47 on its parallel leg surfaces 41 , 43 , behind which the switching ring 17 can be locked after it has been inserted into the U-shaped annular channel 27 .
Das Befestigen des Trägers 19 mit dem Schaltring 17 erfolgt durch das ohnehin schon vorhandene Wickelkopfband 49 für die Wicklungs köpfe 9, 11. Hierdurch wird auch gleichzeitig die Montage des Trägers 19 vereinfacht.The attachment of the carrier 19 with the switching ring 17 is done by the already existing winding headband 49 for the winding heads 9 , 11th This also simplifies the assembly of the carrier 19 .
Im Rahmen der Erfindung kann der Schaltring 18 gemäß Fig. 4 auch einen rechteckförmigen Querschnitt aufweisen, der dann in einem entsprechend ausgebildeten Ringkanal 20 eines Hohlzylinderringes 22 einlegbar ist.In the context of the invention, the switching ring 18 according to FIG. 4 can also have a rectangular cross section, which can then be inserted in a correspondingly designed ring channel 20 of a hollow cylinder ring 22 .
