Die Aufgabe der Erfindung besteht darin, ein neues, verein- fachtes Bürstensystem anzugeben.The object of the invention is to specify a new, simplified brush system.
Diese Aufgabe wird durch ein Bürstensystem mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen des im Anspruch 1 angegebenen Bürstensystems sind in den abhängigen Ansprüchen 2 - 6 ange¬ geben. Die Patentansprüche 7 - 9 betreffen einen Kraftfahrzeug-Stellantrieb mit einem Gehäuse, in welches ein Bürsten¬ system nach einem der Ansprüche 1 - 6 eingesetzt ist.This object is achieved by a brush system with the features specified in claim 1. Advantageous embodiments and further developments of the brush system specified in claim 1 are given in the dependent claims 2-6 . The claims 7 - 9 relate to a motor vehicle actuator with a housing, in which a brush ¬ system according to one of claims 1-6 is used.
Die Vorteile der Erfindung bestehen insbesondere darin, dass die externe Kontaktierung der Leiterbahnen der Platine, auf welcher Entstörbauteile vorgesehen sind, durch die Blattfe¬ dern erfolgt, auf denen die Kohlebürsten platziert sind. Durch diese Mehrfachfunktion der Blattfedern werden keine zu- sätzlichen Befestigungselemente und damit keine zusätzlichen Verbindungsprozesse benötigt, um die externe Kontaktierung der Leiterbahnen der Platine zu realisieren. Dies bedeutet eine Reduzierung der zur Realisierung eines Bürstensystems notwendigen Bauteile sowie eine Verringerung der Anzahl der durchzuführenden Verbindungsprozesse.The advantages of the invention are, in particular, that the external contacting of the conductor tracks of the board on which suppression components are provided by the Blattfe ¬ countries takes place, on which the carbon brushes are placed. Due to this multiple function of the leaf springs, no additional fastening elements and thus no additional connection processes are required in order to realize the external contacting of the conductor tracks of the board. This means a reduction of the necessary components for the realization of a brush system and a reduction in the number of connection processes to be performed.
Die Blattfedern sind in vorteilhafter Weise an Lötpads angelegt, die auf der Platine vorgesehen und mit jeweils einer Leiterbahn der Platine kontaktiert sind. Diese Anlage an die Lötpads wird dadurch begünstigt, dass die Blattfedern, die vorzugsweise aus Kupferblech bestehen, elastisch verformbar sind und nicht relaxieren. Dadurch ist sichergestellt, dass über die gesamte Betriebs- bzw. Lebensdauer des Bürstensys¬ tems die nötige Andrückkraft gegeben ist.The leaf springs are applied in an advantageous manner to solder pads, which are provided on the board and contacted with a respective conductor track of the board. This attachment to the solder pads is facilitated by the fact that the leaf springs, which are preferably made of copper sheet, are elastically deformable and not relax. This ensures that over the entire service life of the Bürstensys ¬ tems the necessary pressure force is given.
Ein weiterer Vorteil der Erfindung besteht darin, dass die Entstörbauteile in der Nähe der Kohlebürsten platziert werden können, was den Entstörvorgang begünstigt.Another advantage of the invention is that the suppression components can be placed in the vicinity of the carbon brushes, which favors the Entstörvorgang.
Weitere vorteilhafte Eigenschaften der Erfindung ergeben sich aus deren beispielhafter Erläuterung anhand der Figuren. Es zeigtFurther advantageous features of the invention will become apparent from the exemplification thereof with reference to the figures. It shows

Die Figur 1 zeigt eine Frontansicht eines Bürstensystems ge¬ mäß einem Ausführungsbeispiel für die Erfindung.1 shows a front view of a brush system ge ¬ Mäss one embodiment of the invention.
Das dargestellte Bürstensystem weist Kohlebürsten Ia, Ib auf, die in Positionierungshilfen 2a, 2b platziert sind. Die Koh- lebürste Ia ist an einer aus Kupferblech bestehenden Blattfeder 3a befestigt, die Kohlebürste Ib an einer ebenfalls aus Kupferblech bestehenden Blattfeder 3b. Diese Blattfedern sind elastisch verformbar und können einen vorgespannten Zustand über einen langen Zeitraum aufrechterhalten ohne zu relaxie- ren.The illustrated brush system has carbon brushes 1a, 1b which are placed in positioning aids 2a, 2b. The carbon brush Ia is fastened to a leaf spring 3a consisting of copper sheet, the carbon brush Ib to a leaf spring 3b also made of copper sheet. These leaf springs are elastically deformable and can maintain a prestressed state for a long period of time without relaxing.
Die Blattfeder 3a ist an einem Stanzkontakt 6a befestigt, beispielsweise mittels einer Schweiß-, einer Schraub- oder einer Nietverbindung 8a. Die Blattfeder 3b ist an einem Stanzkontakt 6b befestigt, beispielsweise mittels einer Schweiß-, einer Schraub- oder einer Nietverbindung 8b.The leaf spring 3a is attached to a punched contact 6a, for example by means of a welding, a screw or a rivet connection 8a. The leaf spring 3b is fixed to a punched contact 6b, for example by means of a welding, a screw or a rivet 8b.
Vorzugsweise bestehen die Stanzkontakte 6a und 6b aus einem elektrisch leitfähigen Material, so dass die Kohlebürsten über die jeweilige Blattfeder mit dem jeweiligen Stanzkontakt elektrisch kontaktiert sind.Preferably, the stamped contacts 6a and 6b made of an electrically conductive material, so that the carbon brushes are electrically contacted via the respective leaf spring with the respective punching contact.
Vorzugsweise ist der Stanzkontakt 6a in seinem in der Figur 1 rechten Endbereich mit einem Fortsatz 9a versehen, über welchen er mit einer externen Stromführung kontaktiert ist, beispielsweise einer Elektronikeinheit oder einem Stecker. Der Stanzkontakt 6b ist vorzugsweise in seinem in der Figur 1 rechten Endbereich mit einem Fortsatz 9b versehen, über welchen er ebenfalls mit der externen Stromführung kontaktiert ist.Preferably, the punching contact 6a is provided in its right in the figure 1 end portion with an extension 9a, via which it is contacted with an external power supply, such as an electronic unit or a plug. The punching contact 6b is preferably provided in its right in the figure 1 end portion with an extension 9b, via which it is also contacted with the external power supply.
Weiterhin weist das in der Figur 1 gezeigte Bürstensystem ei- ne Platine 4 auf, die als Träger für Entstörbauteile 5a, 5b, 5c dient. Im Inneren der Platine oder auf deren Oberfläche sind Leiterbahnen 16a, 16b vorgesehen, über welche die Entstörbauteile miteinander verschaltet sind.Furthermore, the brush system shown in FIG. 1 has a circuit board 4, which serves as a support for suppressor components 5a, 5b, 5c. In the interior of the board or on the surface of conductor tracks 16a, 16b are provided, via which the suppression components are interconnected.
Ferner ist die Leiterbahn 16a mit einem Lötpad 7a elektrisch verbunden, das auf der Platine 4 vorgesehen ist. Die Leiterbahn 16b ist mit einem Lötpad 7b elektrisch verbunden, das ebenfalls auf der Platine 4 vorgesehen ist.Further, the wiring 16a is electrically connected to a solder pad 7a provided on the board 4. The trace 16b is electrically connected to a solder pad 7b, which is also provided on the board 4.
Am Lötpad 7a liegt ein Ende der Blattfeder 3a an, am Lötpad 7b ein Ende der Blattfeder 3b. Dadurch sind die Leiterbahnen 16a, 16b der Platine 4 über die Lötpads 7a, 7b und die Blatt¬ federn nach außen elektrisch kontaktiert. Ein Anliegen der Enden der Blattfedern 3a und 3b an den Löt- pads ist für diese externe elektrische Kontaktierung ausrei¬ chend, da für die Entstörung beispielsweise des Fensterheber- motors in einem Kraftfahrzeug keine hohen Leistungen übertra¬ gen werden müssen. Eine dauerhafte elektrische Kontaktierung ist dadurch sichergestellt, dass die Blattfedern aus Kupfer¬ blech bestehen. Bei Kupferblech handelt es sich um ein Material, das über seine gesamte Lebensdauer eine Andrückkraft aufbringen kann, da das Material elastisch verformbar bzw. federnd ist und auch nicht relaxiert. Folglich können die aus Kupferblech bestehenden Blattfedern die gewünschte Andrückfunktion übernehmen, ohne dass zusätzliche Bauteile notwendig sind. Die damit verbundenen Vorteile bestehen darin, dass zu- sätzliche Bauteile zu einer externen elektrischen Kontaktie¬ rung der Leiterbahnen der Platine eingespart werden können und dass demzufolge bei der Herstellung des Bürstensystems auch keinerlei diesbezügliche Verbindungsprozesse benötigt werden .At the solder pad 7a is one end of the leaf spring 3a, at the solder pad 7b one end of the leaf spring 3b. As a result, the conductor tracks 16a, 16b of the board 4 via the solder pads 7a, 7b and the leaf ¬ springs outwardly contacted electrically. A concern of the ends of the leaf springs 3a and 3b to the solder pads for these external electrical contact suffi ¬ cient as for filtering motor example of the power window in a vehicle, no high performance must be gen übertra ¬. A permanent electrical contact is ensured by the fact that the leaf springs made of copper ¬ sheet. Copper sheet is a material that can apply a pressing force over its entire service life, since the material is elastically deformable or springy and also does not relax. Consequently, the leaf springs made of copper sheet can take over the desired Andrückfunktion without additional components are necessary. The associated advantages consist in the fact that supply additional components to an external electrical PLEASE CONTACT ¬ tion of the conductor tracks of the circuit board can be saved and that therefore also requires no related connection processes in the manufacture of the brush system.
Die mit den Blattfedern 3a, 3b kontaktierten Stanzkontakte 6a, 6b bestehen vorzugsweise ebenfalls aus einem elektrisch leitfähigen Material. Beispielsweise handelt es sich bei die¬ sen Stanzkontakten 6a, 6b um gebogene Stanzgitter.The punched contacts 6a, 6b contacted with the leaf springs 3a, 3b preferably also consist of an electrically conductive material. For example, it is at the stamping ¬ sen contacts 6a, 6b to bent punched grid.
Der Stanzkontakt 6a ist - wie bereits oben ausgeführt wurde - über seinen Fortsatz 9a und der Stanzkontakt 6b über seinen Fortsatz 9b nach außen elektrisch kontaktiert, beispielsweise mit einer externen Elektronikeinheit oder einem Stecker.The punching contact 6a is - as already stated above - electrically contacted via its extension 9a and the punching contact 6b via its extension 9b to the outside, for example with an external electronics unit or a plug.
Die Figur 2 zeigt eine Teilansicht des Gehäuses eines Kraft¬ fahrzeug-Stellantriebs, in welches das Bürstensystem gemäß der Figur 1 eingesetzt ist. Aus dieser Figur 2 ist ersieht- lieh, dass das Gehäuse 17, bei dem es sich um ein Kunststoff¬ gehäuse handelt, in seinem mittleren Bereich eine von einem Gehäuseteil 13 umgebene, im Wesentlichen runde Aussparung hat, durch welche beim Zusammenbau des Stellantriebs der Kom- mutator eines Elektromotors derart eingeführt wird, dass er zwischen den Kohlebürsten Ia und Ib zum Liegen kommt. Weiterhin geht aus der Figur 2 hervor, dass die Platine 4 von Hal¬ teelementen 14 und 15 gehalten ist, die Bestandteile einer Platinentasche sind.2 shows a partial view of the housing of a power ¬ vehicle actuator, in which the brush system is used according to the figure 1. From this Figure 2 is seen- lent that the housing 17, which is a plastic ¬ housing, in its central region surrounded by a housing part 13, has substantially round recess through which the commutator of an electric motor is introduced in such an assembly of the actuator in that it comes to rest between the brushes Ia and Ib. Furthermore, it is apparent from the figure 2 that the board 4 is held by Hal ¬ teelementen 14 and 15, which are components of a board pocket.
Ferner ist aus der Figur 2 ersichtlich, dass der in der Figur auf der linken Seite der Kohlebürsten Ia und Ib gelegene Be¬ reich der Blattfedern 3a, 3b zwischen Führungselementen IIa, IIb; 12a, 12b des Gehäuses 17 hindurchgeführt ist.Furthermore, it can be seen from FIG. 2 that the region of the leaf springs 3 a, 3 b located between the guide elements 11 a, 11 b in the figure on the left side of the carbon brushes 1 a and 1 b; 12a, 12b of the housing 17 is passed.
Schließlich geht aus der Figur 2 hervor, dass die Fortsätze 9a, 9b der Stanzkontakte 6a, 6b in Aufnahmeelemente 10a, 10b des Gehäuses 17 eingeschoben sind, die jeweils eine Aufnahme¬ nut bilden. An bzw. in diesen Aufnahmeelementen kann jeweils die elektrische Kontaktierung des Bürstensystems mit einer externen Elektronikeinheit oder einem externen Stecker erfolgen . Finally, it can be seen from FIG. 2 that the extensions 9a, 9b of the stamped contacts 6a, 6b are inserted into receiving elements 10a, 10b of the housing 17, each of which forms a receiving groove . At or in these receiving elements can each be made the electrical contacting of the brush system with an external electronics unit or an external plug.
