Description
Bürstenhalter Brush holder
Die Erfindung bezieht sich auf einen Bürstenhalter, der einen aus Isolierstoff bestehenden Träger aufweist, an dem ein Aufnahmegehäuse für die Bürste mit einer Seite sowie eine auf die Bürste wirkende Druckfeder angebracht sind und der in das Motorgehäuse einsteckbar ist.The invention relates to a brush holder, the one from Has insulating material existing carrier on which a housing for the brush with one side and a compression spring acting on the brush are attached and which can be inserted into the motor housing.
Ihr liegt die Aufgabe zugrunde, einen derartigen Träger so auszugestalten, daß er eine raumsparende Kompakteinheit bildet, die rasch und sicher montierbar ist und bei der Montage zugleich die elektrischen Verbindungen herstellt.It is based on the task of designing such a carrier in such a way that that it forms a space-saving compact unit that can be installed quickly and safely and at the same time establishes the electrical connections during assembly.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß der Träger beidseitig jeweils wenigstens eine Führungs leiste enthält, die sich quer zur Längsachse des Bürstenaufnahmegehäuses in Richtung dessen beider freien Außenflächen erstreckt, und daß am Träger zwei im Abstand -von den Führungsleisten und parallel zu diesen verlaufende Steckhülsen für die Aufnahme von Steckanschlüssen der Feldwicklung sowie die Entstördrossel und die Verbindungsleitungen von den Steckhülsen zum Schalter gehaltert sind.This object is achieved according to the invention in that the carrier is on both sides each contains at least one guide bar that extends transversely to the longitudinal axis of the Brush receiving housing extends in the direction of its two free outer surfaces, and that on the carrier two at a distance from the guide strips and parallel to them running receptacles for the inclusion of plug-in connections of the field winding as well as the interference suppression choke and the connecting cables from the receptacles to the switch are held.
Die Erfindung wird im nachstehenden anhand der Zeichnung, die ein Ausführungsbeispiel schematisch veranschaulicht, erläutert.The invention is in the following with reference to the drawing, which a Exemplary embodiment illustrated schematically, explained.
Es zeigen: Fig. 1 eine Yorderansicht des Bürstenhalters (Richtung A in Fig.6), Fig. 2 eine Draufsicht auf den Bürstenhalter gemäß Fig.1, Fig. 5 eine Seitenansicht des Bürstenhalters nach Fig.1 in Richtung B, Fig, 4 eine Ansicht des Bürstenhalters gemäß Fig.3 in Richtung C, Fig. 5 den montierten Bürstenhalter in der Ansicht von oben, Fig. 6 den Bürstenhalter .im montierten Zustand im Antriebsmotor in Seitenansicht Fig. 7 einen Teilschnitt durch das Maschinengehäuse im Bereich des Handgriffteilso In den Figuren 1 bis 4 ist mit 1 der Träger bezeichnet, an dem das Aufnahmegehäuse 2 für die Bürste 3, die auf die Bürste 3 einwirkende Spiralfeder 4, die Steckhülsen 5 und 6 sowie die Entstördrossel 7 befestigt sind, desgleichen die Verbindungsleitung 8 zum hier nicht gezeichneten Ein- und Ausschalter des betreffenden Elektrowerkzeugs.1 shows a front view of the brush holder (direction A in FIG. 6), FIG. 2 a plan view of the brush holder according to FIG. 1, FIG. 5 a Side view of the brush holder according to FIG. 1 in the direction B, FIG. 4 is a view of the Brush holder according to Fig. 3 in direction C, Fig. 5 in the mounted brush holder the view from above, FIG. 6 shows the brush holder in the mounted state in the drive motor in side view FIG. 7 shows a partial section through the machine housing in the area of the handle part so In Figures 1 to 4, 1 denotes the carrier on which the housing 2 for the brush 3, the spiral spring acting on the brush 3 4, the receptacles 5 and 6 and the interference suppression choke 7 are attached, the same the connecting line 8 to the on and off switch, not shown here, of the relevant Power tool.
Der Träger 1 weist beidseitig eine Führungsleiste 9,10 auf, die sich jeweils quer zur Längsachse 11 des Bürstenaufnahmegehäuses 2 erstrecken und zumindest angenahert parallel zu dessen Außenflächen 12,13 verlaufen. Gegebenenfalls können auf jeder Seite des Trägers 1 auch zwei oder mehr J?ührt;ngsleisten 9,10 im Abstand voneinander angeordnet sein, ebenso kann die Anzahl der Puhrungsleisten je Seite des Trägers 1 auch verschieden sein.The carrier 1 has on both sides a guide strip 9, 10, which each extend transversely to the longitudinal axis 11 of the brush receiving housing 2 and at least run approximately parallel to its outer surfaces 12, 13. If necessary, can on each side of the carrier 1 there are also two or more junction strips 9, 10 spaced apart be arranged from each other, as well as the number of Puhrungsträger per side of the carrier 1 can also be different.
An die bezogen auf die Längsachse 11 der Bürsten 3 bzw. der BürsteShalterführung 2 etwa rechtwinklig verlaufenden, im Träger 1 eingebetteten Steckhülsen 5,6 sind die Verbindungsleitungen 14,15 zum nicht dargestellten Schalter des Kollektormotors angeschlossen. Die Entstördrossel 7 ist mit dem Winkelstecker 6 und der aus Blech bestehenden Bürstenhalterführung 2 leitend verbunden('Fig.4).In relation to the longitudinal axis 11 of the brushes 3 or the BürsteShalterführung 2 are approximately at right angles, embedded in the carrier 1 receptacles 5,6 the connecting lines 14,15 to the switch, not shown, of the collector motor connected. The interference suppression choke 7 is made of sheet metal with the angle connector 6 existing brush holder guide 2 conductively connected ('Fig. 4).
Wie aus Fig.5 ersichtlich ist, sind innen am Motor gehäuse 16 parallel zur Motorachse verlaufende, räumlich um ca. 1800 gegeneinander versetzte, U-förmig oder ähnlich ausgebildete Führungen 17,18 für die Aufnahme der Führungsleisten 9,10 des Trägers 1 vorgesehen.As can be seen from Figure 5, the inside of the motor housing 16 are parallel U-shaped, running towards the motor axis, spatially offset from one another by approx. 1800 or similarly designed guides 17, 18 for receiving the guide strips 9, 10 of the carrier 1 is provided.
Der Träger 1 braucht mit seinen-Leißten 9 und 10 also lediglich in diese Führungen eingesteckt zu werden.The carrier 1 therefore only needs with its strips 9 and 10 in these guides get plugged in.
Beim Einstecken des Trägers 1 in die Führungen 17,18 übergreifen; wie Fig.6 zeigt, zugleich die Steckhülsen 5 und 6 die Steckanschlüsse 19,20 der Feldwicklung 21, die in der aus Isolierstoff bestehenden Endscheibe 22 des Statorblechpakets angeordnet sind. Dadurch ist die leitende Verbindung der Feldwicklungbis zum Schalter wie auch die Verbindung der Entstördrossel 7 zum Schalter hergestellt (Zuleitungen 14 und 15).When the carrier 1 is inserted into the guides 17, 18; As Figure 6 shows, at the same time the receptacles 5 and 6, the plug connections 19.20 of the Field winding 21, which is made of insulating material in the end plate 22 of the stator core are arranged. This creates the conductive connection between the field winding and the switch as well as the connection of the interference suppression choke 7 to the switch established (supply lines 14 and 15).
Die Fixierung des Bürstenhalters in axialer Richtung wird durch das Motorgehäuse 16 und die Handgriff schalen 23,24 erreicht.The fixation of the brush holder in the axial direction is made possible by the Motor housing 16 and the handle shells 23,24 reached.
Zu diesem Zweck ist das Notorgehäuse 16, wie Fig.7 erkennen'läßt, mit rippenförmigen Ansätzen 25 und 26 versehen. Nit 27 ist der Ein- und Ausschalter des Elektrowerkzeugs bezeichnet.For this purpose, the notor housing 16, as shown in FIG. 7, is provided with rib-shaped projections 25 and 26. Nit 27 is the on and off switch of the power tool.
Es ist ersichtlich, daß durch die zugleich mit der Montage der-Bürstenhalter einhergehende Eontaktlerung nicht nur eine Zeitersparnis erzielt wird sondern infolge der räumlich definierten Zuordnung der Bau-und Kontaktteile auch Schaltfehler praktisch ausgeschlossen sind.It can be seen that by the same time with the assembly of the brush holder accompanying Eontaktlerung not only a time saving is achieved but as a result the spatially defined assignment of the components and contact parts also makes switching errors practical excluded are.
Der Träger 1 wird vorzugsweise aus einem hochwårmefesten, spritzbaren Kunststoff hergestelltThe carrier 1 is preferably made of a highly heat-resistant, sprayable Made of plastic
