Description

Die Erfindung betrifft eine elektrische Anschlußeinrichtung für eine eine Kohlebürste aufnehmende elektrisch leitfähige Bürstenhülse, mit der die Kohlebürste ihrerseits elektrisch leitend verbunden ist, bei welcher Einrichtung ferner die Bürstenhülse in einen Führungsschacht eines einer elektrischen Maschine zugeordneten Bürstenträgers eingesetzt ist und mit einer mit einer elektrischen Zuführleitung verbundenen Kontaktfahne in elektrischer Verbindung steht.The invention relates to an electrical connection device for an electrically conductive brush sleeve receiving a carbon brush, to which the carbon brush is in turn connected in an electrically conductive manner, in which device the brush sleeve is also inserted into a guide shaft of a brush holder assigned to an electrical machine and connected to an electrical supply line Contact lug is in electrical connection.

Eine solche Anschlußeinrichtung ist durch die DE-OS 17 63 023 bekannt. Bei dieser Einrichtung wird die Kontaktfahne in einem gesonderten Arbeitsgang an der Bürstenhülse befestigt. Die Bürstenhülse selbst wird an den Bürstenträger mit Kunststoff umspritzt und dadurch gehalten. Die Zuführleitung wird nach der Montage der Bürstenhülse an die Kontaktfahne angeschlossen, wobei dieser Anschluß unter den beengten Raumverhältnissen an der elektrischen Maschine erfolgen muß.Such a connection device is known from DE-OS 17 63 023. With this device, the contact lug is attached to the brush sleeve in a separate operation. The brush sleeve itself is overmolded with plastic on the brush holder and held thereby. The supply line is connected to the contact lug after assembly of the brush sleeve, this connection having to be made on the electrical machine in a confined space.

Der Erfindung liegt die Aufgabe zugrunde, eine Anschlußeinrichtung der eingangs beschriebenen Art so auszubilden, daß eine Befestigung der Kontaktfahne an der Bürstenhülse nicht mehr notwendig ist.The invention has for its object to provide a connection device of the type described above so that attachment of the contact tab to the brush sleeve is no longer necessary.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß die Kontaktfahne durch eine öffnung in der Wand des Führungsschachtes hindurchgesteckt ist und mindestens soweit in den Führungsschacht ragt, daß die Bürstenhülse beim Einschieben in den Führungsschacht mit der Kontaktfahne in Berührung kommt. Damit kann bei einer solchen Abschlußeinrichtung die Kontaktfahne bereits vor dem Einstecken in die öffnung mit der Zuführleitung verbunden werden. Ein Verbinden der Kontaktfahne mit der Bürstenhülse in einem gesonderten Arbeitsgang entfällt, da die elektrische Verbindung selbsttätig beim Einschieben der Bürstenhülse in den Führungsschacht hergestellt wird.The object is achieved according to the invention in that the contact lug is inserted through an opening in the wall of the guide shaft and protrudes into the guide shaft at least to such an extent that the brush sleeve comes into contact with the contact lug when inserted into the guide shaft. So that with a such a termination device, the contact tab is connected to the feed line before it is inserted into the opening. There is no need to connect the contact lug to the brush sleeve in a separate operation, since the electrical connection is established automatically when the brush sleeve is inserted into the guide shaft.

Eine besonders sichere elektrische Verbindung zwischen der Kontaktfahne und der Bürstenhülse wird dadurch erreicht, daß die Kontaktfahne so weit in den Führungsschacht hineinragt, daß sie beim Einschieben der Bürstenhülse umgebogen ist. Durch das Umbiegen wird sichergestellt, daß die Kontaktfahne stets an die Bürstenhülse angedrückt ist.A particularly secure electrical connection between the contact lug and the brush sleeve is achieved in that the contact lug protrudes so far into the guide shaft that it is bent over when the brush sleeve is inserted. The bending ensures that the contact tab is always pressed onto the brush sleeve.

Ein Verklemmen der Bürstenhülse beim Einschieben in den Führungsschacht wird dadurch verhindert, daß sich an die öffnung eine in Einschiebrichtung der Bürstenhülse erstreckende Aufnahmerinne anschließt, deren Tiefe gegenüber der Führungsfläche der betreffenden Wand des Führungsschachtes höchstens gleich der Materialstärke der Kontaktfahne und deren Länge mindestens gleich der Länge des umgebogenen Teiles der Kontaktfahne ist. Die Kontaktfahne legt sich beim Umbiegen in die Aufnahmerinne und verengt damit nicht den Querschnitt des Führungsschachtes.A jamming of the brush sleeve during insertion into the guide shaft is prevented by the opening being followed by a receiving groove extending in the insertion direction of the brush sleeve, the depth of which relative to the guide surface of the relevant wall of the guide shaft is at most equal to the material thickness of the contact tab and its length is at least equal to the length of the bent part of the contact lug. The contact lug lies in the receiving channel when it is bent over and thus does not narrow the cross section of the guide shaft.

Eine besonders vorteilhafte Ausführungsform der Anschlußeinrichtung ergibt sich in Verbindung mit einem in Reihenschluß geschalteten und in einem Kunststoffgehäuse eingesetzten Universalmotor dadurch, daß die Führungsschächte stirnseitig an dem Kunststoffgehäuse angeformt und die Kontaktfahnen mit der Ständerwicklung des Motors verbunden und an dem die Wickelköpfe der Ständerwicklung abstützenden Wicklungsträger axial vorstehend befestigt sind und daß ferner die öffnung für das Durchstecken der Kontaktfahne jeweils in dem den Führungsschacht begrenzenden Wandteil des Kunststoffgehäuses vorgesehen ist.A particularly advantageous embodiment of the connection device results in connection with a universal motor connected in series and inserted in a plastic housing in that the guide shafts are integrally formed on the front side of the plastic housing and the contact tabs are connected to the stator winding of the motor and on which the winding supports of the stator winding support axially are attached above and that the opening for pushing through the contact lug is provided in each case in the wall part of the plastic housing delimiting the guide shaft.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird die Erfindung nachfolgend näher beschrieben. Es zeigt

  • Fig. 1 eine Anschlußeinrichtung im Schnitt und
  • Fig. 2 eine Anschlußeinrichtung in Kombination mit einem in einem Kunststoffgehäuse eingebauten Universalmotor.
The invention is described in more detail below on the basis of an exemplary embodiment shown in the drawing. It shows
  • Fig. 1 shows a connection device in section and
  • Fig. 2 shows a connection device in combination with a universal motor built into a plastic housing.

In einen an einen Bürstenträger 1 vorgesehenen Führungsschacht 2 ist eine Bürstenhülse 3 eingesetzt. Durch aus der Wandung der Bürstenhülse 3 herausgebogene Rastzungen Sund 6, die in einer in der einen Wand des Führungsschachtes 2 vorgesehenen Vertiefung 7 verrasten, wird die Bürstenhülse 3 in dem Führungsschacht 2 gehalten. In der Bürstenhülse 3 befindet sich eine Kohlebürste 4, die durch eine Feder 8 gegen den Kollektor 9 einer elektrischen Maschine gedrückt wird. Die Feder 8 ist an ihrem der Kohlebürste 4 gegenüberliegenden Ende an einem aus der Wandung der Bürstenhülse 3 herausgebogenen Vorsprung 10 abgestützt. Die elektrische Verbindung der Kohlebürste 4 mit der Bürstenhülse 3 kann über die Feder 8 oder eine gesonderte Litze (in der Zeichnung nicht dargestellt), welche mit der Kohlebürste 4 und der Bürstenhülse 3 verbunden ist, erfolgen. Die Stromzuführung zur Bürstenhülse 3 erfolgt über eine Kontaktfahne 13, die durch eine in der den Führungsschacht 2 begrenzenden Wand 11 des Bürstenträgers vorgesehene öffnung 12 hindurchgesteckt ist. An diese Kontaktfahne 13 ist eine Zuführleitung 14 angeschlossen. Wie die Darstellung in Fig. 1 zeigt, ist das in den Führungsschacht 2 hineinragende Ende 15 der Kontaktfahne 13 umgebogen und liegt in einer Aufnahmerinne 16 . Die Kontaktfahne 13 ist im ursprünglichen Zustand gerade ausgebildet, so daß sie leicht durch die öffnung 12 hindurchgesteckt werden kann. Beim Einschieben der Bürstenhülse 13 in den Führungsschacht 2 wird das in den Führungsschacht 2 hineinragende Ende 15 umgebogen und legt sich in die Aufnahmerinne 16. Durch das über die Bürstenhülse 3 erfolgende Umbiegen der Kontaktfahne 13 ist sichergestellt, daß diese fest an der Bürstenhülse 3 anliegt und damit in elektrisch gut leitender Verbindung mit der Bürstenhülse 3 steht.A brush sleeve 3 is inserted into a guide shaft 2 provided on a brush holder 1. The brush sleeve 3 is held in the guide shaft 2 by latching tongues 6, which are bent out of the wall of the brush sleeve 3 and engage in a recess 7 provided in one wall of the guide shaft 2. In the brush sleeve 3 there is a carbon brush 4, which is pressed by a spring 8 against the collector 9 of an electrical machine. The spring 8 is supported at its end opposite the carbon brush 4 on a projection 10 bent out of the wall of the brush sleeve 3. The electrical connection of the carbon brush 4 to the brush sleeve 3 can take place via the spring 8 or a separate strand (not shown in the drawing), which is connected to the carbon brush 4 and the brush sleeve 3. The power supply to the brush sleeve 3 takes place via a contact lug 13 which is inserted through an opening 12 provided in the wall 11 of the brush holder delimiting the guide shaft 2. A feed line 14 is connected to this contact tab 13. As the illustration in FIG. 1 shows, the end 15 of the contact tab 13 protruding into the guide shaft 2 is bent and lies in a receiving groove 16. The contact tab 13 is straight in the original state, so that it can be easily inserted through the opening 12. When the brush sleeve 13 is inserted into the guide shaft 2, the end 15 protruding into the guide shaft 2 is bent and lies in the receiving groove 16. By means of the brush sleeve 3 The contact lug 13 is bent over to ensure that it bears firmly against the brush sleeve 3 and is thus in a good electrical connection with the brush sleeve 3.

In Fig. 2 ist mit 17 der Ständer und mit 18 der Läufer eines Universalmotors bezeichnet, der in ein Kunststoffgehäuse 19 eingebaut ist. Auf der einen Stirnseite des Kunststoffgehäuses 19 sind zwei Führungsschächte 2 angeformt, in die jeweils eine Bürstenhülse 3 eingesetzt ist. Die Wickelköpfe 20 der Ständerwicklung sind durch Wicklungsträger 21 bzw. 22 abgestützt. An den auf der Kollektorseite des Motors angeordneten Wicklungsträgern 22 sind axial vorstehende Kontaktfahnen 23 befestigt. In jedem des den Führungsschächten 2 benachbarten Wandteil 24 des Kunststoffgehäuses 19 ist eine öffnung 25 vorgesehen, durch die die mit dem Wicklungsträger 22 verbundene Kontaktfahne 23 hindurchgesteckt ist. Das Durchstecken der Kontaktfahne 23 durch die öffnung 25 erfolgt beim Einsetzen des Ständers 17 in das Kunststoffgehäuse 19. Beim nachfolgenden Einschieben der Bürstenhülse 3 in den Führungsschacht 2 wird das in den Führungsschacht 2 ragende Ende der Kontaktfahne 23 umgebogen und liegt dadurch an der Bürstenhülse 3 an. Damit ist ohne zusätzliche Anschlußarbeiten die elektrische Verbindung zu der Bürstenhülse 3 hergestellt und die Ständerwicklung mit der Läuferwicklung in Reihe geschaltet.In Fig. 2 with 17 the stator and 18 the rotor of a universal motor, which is installed in a plastic housing 19. On one end face of the plastic housing 19, two guide shafts 2 are formed, in each of which a brush sleeve 3 is inserted. The winding heads 20 of the stator winding are supported by winding supports 21 and 22, respectively. Axially projecting contact lugs 23 are fastened to the winding carriers 22 arranged on the collector side of the motor. In each of the wall parts 24 of the plastic housing 19 adjacent to the guide shafts 2, an opening 25 is provided, through which the contact lug 23 connected to the winding carrier 22 is inserted. The contact lug 23 is pushed through the opening 25 when the stand 17 is inserted into the plastic housing 19. When the brush sleeve 3 is subsequently pushed into the guide shaft 2, the end of the contact lug 23 projecting into the guide shaft 2 is bent and is thereby in contact with the brush sleeve 3 . So that the electrical connection to the brush sleeve 3 is made without additional connection work and the stator winding is connected in series with the rotor winding.

Da das Einschieben des Ständers 17 in das Kunststoffgehäuse 19 und das Einschieben der Bürstenhülse 3 in den Führungsschacht 2 nur in einer einfachen geradlinigen Bewegung erfolgt, kann ein solches Einschieben maschinell vorgenommen werden.Since the insertion of the stand 17 into the plastic housing 19 and the insertion of the brush sleeve 3 into the guide shaft 2 only takes place in a simple linear movement, such insertion can be carried out mechanically.
