Abstract

An electric motor, in particular for motor vehicle windshield wipers, has a gear housing (1) and a lid (3) that closes the gear housing, is secured by at least one fastening element (10) to the gear housing (1) and is provided with at least one conductor element (4) arranged on the lid (3) for electrically connecting the electric motor to a current supply. The invention essentially consists in that the electric conductor elements (2, 4) on the lid (3) and gear housing (1) are electrically interconnected by the fastening element (10) for the lid (3). This allows electric connection plugs (7) for the electric motor to be arranged in any desired position on the housing (1) or lid (3).

Description

Elektromotor, insbesondere Wischermotor für KraftfahrzeugeElectric motor, in particular wiper motor for motor vehicles
Die Erfindung betrifft einen Elektromotor, insbesondere Wischermotor für Kraftfahrzeuge mit einem Getriebegehäuse und einem das Getriebegehäuse verschließenden Deckel, welcher mit mindestens einem Befestigungselement an dem Getriebegehäuse befestigt ist sowie mit mindestens einem an dem Deckel vorgesehenen Leiterelement zum elektrischen Anschluß des Elektromotors an eine Stromzuführung.The invention relates to an electric motor, in particular a wiper motor for motor vehicles, with a gear housing and a cover closing the gear housing, which is fastened to the gear housing with at least one fastening element and with at least one conductor element provided on the cover for the electrical connection of the electric motor to a power supply.
Ein derartiger Elektromotor ist beispielsweise aus der DE-PS 3409680 C2 bekannt. Hierbei sind Leiterelemente und Schleifkontakte an dem Deckel angeordnet und dienen dazu, dem Elektromotor bei bestimmten Positionen der Abtriebsachse Strom zuzuführen, obwohl der zugeordnete Scheibenwischer-Betätigungsschalter die Stromzuführung unterbricht. An dem Dek- kel sind Steckelemente zum elektrischen Anschluß des Elektromotors an das Bordnetz angeordnet. Die grundsätzliche Anordnung der Steckelemente an der Deckelseite^wird als nachteilig angesehen. Zwar ist es denkbar, die Steckerelemente mit zusätzlichen, an dem Gehäuse anzuordnenden Leiterelementen zu verlegen aber dies würde zu einem erhöhten Montageaufwand führen. Schließlich könnten an der Gehäuseaußenseite angeordnete Leiterelemente beschädigt werden. Eine Stromdurchführung auf der Gehäuseinneseite ist wegen der beengten Platzverhältnisse nicht möglich.Such an electric motor is known for example from DE-PS 3409680 C2. Here, conductor elements and sliding contacts are arranged on the cover and serve to supply current to the electric motor at certain positions on the output axis, although the assigned windshield wiper actuation switch interrupts the current supply. Plug elements for the electrical connection of the electric motor to the vehicle electrical system are arranged on the cover. The basic arrangement of the plug elements on the cover side ^ is regarded as disadvantageous. Although it is conceivable to lay the plug elements with additional conductor elements to be arranged on the housing, this would lead to increased assembly effort. Finally, conductor elements arranged on the outside of the housing could be damaged. A current feedthrough on the inside of the housing is not possible due to the limited space.
Aufgabe der vorliegenden Erfindung ist es daher, eine besonders einfache, montagefreundliche und ferner kostengünstige Stromzuführung bereitzustellen, welche es ferner erlaubt, Steckelemente zum elektrischen Anschluß des Elektromotors an beliebiger Stelle anzuordnen.The object of the present invention is therefore to provide a particularly simple, easy-to-assemble and also inexpensive To provide power supply, which also allows plug elements for the electrical connection of the electric motor to be arranged at any point.
Diese Aufgabe wird dadurch gelöst, daß an dem Deckel und dem Getriebegehäuse elektrische Leiterelemente vorgesehen sind, welche mittels des Befestigungselementes für den Deckel elektrisch leitend miteinander verbunden sind. Diese Maßnahme erlaubt unabhängig von der Anordnung von Schleifkontakten im Inneren des Getriebegehäuse oder an dem Deckel, eine beliebige Anordnung von Steckelementen zum elektrischen Anschluß an eine Stromzuführung. Den Befestigungselementen kommt also eine Doppelfunktion zu, wodurch der Montageaufwand verringert wird .This object is achieved in that electrical conductor elements are provided on the cover and the gear housing, which are connected to one another in an electrically conductive manner by means of the fastening element for the cover. This measure allows any arrangement of plug-in elements for electrical connection to a power supply, regardless of the arrangement of sliding contacts inside the gear housing or on the cover. The fasteners therefore have a double function, which reduces the assembly effort.
Weiterbildungen der Erfindung gehen aus Unteransprüchen zusammen mit der Beschreibung und der Zeichnung hervor. Die Erfindung wird nachstehend anhand eines Ausführungsbeispie- les, das in der Fig. dargestellt ist, näher beschrieben. Dabei zeigt:Further developments of the invention emerge from the subclaims together with the description and the drawing. The invention is described in more detail below with the aid of an exemplary embodiment which is shown in the figure. It shows:
Fig. 1 einen teilweise dargestellten Schnitt quer durch ein Getriebegehäuse für einen Elektromotor.Fig. 1 shows a partially shown section across a gear housing for an electric motor.
Die Fig. 1 zeigt einen abgeschnittenen ¥eil eines Getriebegehäuses 1 für einen Elektromotor zum Antrieb von Scheibenwischern mit einem ersten Leiterelement 2, das in das Getriebegehäuse 1 eingebettet ist. Das Getriebegehäusö 1 weist eine nicht gezeichnete Ausnehmung für Getriebebauteile auf, die mit einem Deckel 3 verschlossen ist. In dem Deckel 3 ist ein zweites Leiterelement 4 eingebettet. Sowohl Getriebegehäuse 1 wie auch der Deckel 3 sind beispielsweise aus Kunststoff hergestellt. Die beiden Leiterelemente 2,4 sind in die jeweili¬ gen Bauteile 1,3 elektrisch isoliert eingebettet. Die Leiterelemente 2,4 sind vorzugsweise flach und als Gitter ausge- bildet, so daß sie aus einem Blech ausgestanzt werden können. Grundsätzlich können die Leiterelemente 2,4 beliebig gestal¬ tet und insbesondere auch räumlich strukturiert sein. In der Figur weist das deckelseitige Leiterelement 4 einen Abzweig 5 auf, der rechtwinklig von der Erstreckungsrichtung bezie¬ hungsweise Hauptebene abgebogen ist. An der Oberseite 6 des Deckels 3 ist ein Steckelement 7 vorgesehen, welches elek¬ trisch leitend mit dem Abzweig 5 verbunden ist und dazu dient, eine elektrische Verbindung zu einer nicht dar¬ gestellten Stromzuführung des Bordnetzes eines Kraftfahrzeu¬ ges herzustellen. Es versteht sich, daß der Abzweig 5 auch fluchtend mit der Hauptebene des Leiterelementes 4 angeordnet sein kann, so daß sich das Steckelelement 7 am Umfang des Deckels 3 befindet. Der Deckel 3 weist ferner eine Ausnehmung 8 sowie ein Durchgangsloch 9 für ein Befestigungselement 10 auf. In der Figur ist das Befestigungselement 10 eine elek¬ trisch leitende Schraube mit einem Schraubenkopf 11 und einem Schaft 12, welcher das Durchgangsloch 9 durchgreift und bis in eine Bohrung 13 des Getriebegehäuses 1 eingreift. Der Schraubenkopf 11 liegt mit einer Kontaktfläche 14 auf dem Leiterelement 4 auf. Es können auch andere Befestigungsele¬ mente wie beispielsweise Stifte oder Niete eingesetzt werden. Wesentlich ist, daß diese mit mindestens einer Kontaktfläche 14 elektrisch leitend an dem Leiterelement 4 angeordnet sind und mit einem Schaft in das Getriebegehäuse 1 eingreifen. In der Figur ist die Bohrung 13 mit einem Gewinde 15 für die Schraube versehen, wobei dies nicht zwingend notwendig ist, wenn selbstschneidende Gewindeschrauben eingesetzt werden. Wesentlich ist, daß das Befestigungselement 10 an seinem an¬ deren Ende 16 elektrischen Kontakt zu dem zweiten Leiterele¬ ment 2 aufweist. Das Befestigungselement 10 verbindet also die beiden auf unterschiedlichen Ebenen sowie im Abstand zu¬ einander angeordneten Leiterelemente 2,4. Zu diesem Zweck ist an dem Leiterelement 2 eine Lasche 17 vorgesehen, welche das Befestigungselement 10 zumindest teilweise ringförmig um- greift. Die Lasche 17 ist im wesentlichen rechtwinklig zu der Erstreckungsrichtung des Leiterelementes 2 abgebogen, so daß sie mit einer Kontaktfläche zumindest einen Teil des Umfangs des Befestigungselementes 10 umgreift und einen zuverlässigen elektrischen Kontakt bereitstellt. In Weiterbildung der Erfindung ist es auch denkbar, daß die Lasche 17 das Befestigungselement 10 nach Art einer Mutter vollständig umgreift, so daß eine besonders feste und kontaktsichere Verbindung gegeben ist. Selbstverständlich kann das Leiterelement 2 mit einem Gewinde für die Befestigungsschraube versehen sein. Dadurch kann das Gewinde 15 in dem Gehäuse 1 entfallen.1 shows a cut-off part of a gear housing 1 for an electric motor for driving windshield wipers with a first conductor element 2 which is embedded in the gear housing 1. The gear housing 1 has a not shown recess for gear components, which is closed with a cover 3. A second conductor element 4 is embedded in the cover 3. Both the gear housing 1 and the cover 3 are made of plastic, for example. The two conductor elements 2,4 are embedded in the jeweili ¬ gen 1.3 parts electrically insulated. The conductor elements 2, 4 are preferably flat and designed as a grid. forms so that they can be punched out of a sheet. Basically, the conductor elements 2,4 can arbitrarily tet decor with dark ¬ and be structured in particular spatially. In the figure 4, the cover-side conductor element at a junction 5, the right angle from the extending direction rela ¬ hung as principal plane is bent. At the top side 6 of the lid 3, a male member 7 is provided which is conductively connected elec tric ¬ with the branch 5 and serves to establish an electrical connection to a power supply not represent ¬ made of the electrical system of a Kraftfahrzeu ¬ sat. It goes without saying that the branch 5 can also be aligned with the main plane of the conductor element 4, so that the plug element 7 is located on the circumference of the cover 3. The cover 3 also has a recess 8 and a through hole 9 for a fastening element 10. In the figure, the fastener 10 is an elec trically conductive ¬ screw with a screw head 11 and a shank 12 which extends through the through hole 9 and engages the gear housing 1 into a bore. 13 The screw head 11 lies on the conductor element 4 with a contact surface 14. Other fastening elements such as pins or rivets can also be used. It is essential that these are arranged in an electrically conductive manner on the conductor element 4 with at least one contact surface 14 and engage in the gear housing 1 with a shaft. In the figure, the bore 13 is provided with a thread 15 for the screw, although this is not absolutely necessary if self-tapping threaded screws are used. It is essential that the fastening element has at its end at ¬ whose ment 16 electrical contact to the second Leiterele ¬ 2 10th The fastening element 10 thus connects the two at different levels and at a distance from ¬ stacked conductor elements 2,4. For this purpose, a tab 17 is provided on the conductor element 2, which at least partially annularly surrounds the fastening element 10. takes hold. The tab 17 is bent substantially at right angles to the direction of extension of the conductor element 2, so that it engages around at least part of the circumference of the fastening element 10 with a contact surface and provides a reliable electrical contact. In a further development of the invention, it is also conceivable that the tab 17 completely engages around the fastening element 10 in the manner of a nut, so that a particularly firm and contact-safe connection is provided. Of course, the conductor element 2 can be provided with a thread for the fastening screw. As a result, the thread 15 in the housing 1 can be omitted.
Hervorzuheben ist, daß die Leiterelemente 2,4 im übrigen keinerlei Kontaktfläche zueinander aufweisen, weil Gehäuse 1 und Deckel 3 mit zugeordneten Grundflächen 18,19 unmittelbar aneinander aufliegen. Im Unterschied zu der vorstehend beschriebenen Anordnung der Steckeinrichtung 7 kann es angezeigt sein, diese gehäuseseitig anzuordnen, was in der Fig. gestrichelt dargestellt ist. Die elektrische Verbindung der Leiterelemente 2,4 mit Hilfe des Befestigungselementes 10 erlaubt grundsätzlich eine beliebige Anordnung der Steckeinrichtung 7, ohne auf eine Positionierung an einem bestimmten Ort des Deckels 3 festgelegt zu sein. Durch einfache Änderung des Abzweigs 5 in seiner Lage zu dem jeweiligen Leiterelement 2,4 und entsprechende Einbettung in das^ntsprechende Bauteil 1,3 sind beliebige Anordnungspunkte der Steckeinrichtung 7 denkbar.It should be emphasized that the conductor elements 2, 4 do not have any contact surface with one another, because the housing 1 and cover 3 with associated base surfaces 18, 19 lie directly against one another. In contrast to the arrangement of the plug device 7 described above, it may be appropriate to arrange this on the housing side, which is shown in dashed lines in the FIG. The electrical connection of the conductor elements 2, 4 with the aid of the fastening element 10 basically allows any arrangement of the plug-in device 7 without being fixed to a positioning at a specific location of the cover 3. By simply changing the branch 5 in its position relative to the respective conductor element 2, 4 and correspondingly embedding it in the corresponding component 1, 3, any arrangement points of the plug-in device 7 are conceivable.
Anzumerken ist, daß in dem Gehäuse 1 und dem Deckel 3 jeweils auch mehrere, einander zugeordnete Leiterlemente 2,4 angeordnet sein können, welche auf die vorstehen beschreibende Art und Weise miteinander verbunden sind. Es ist dabei insbesondere an einen positiv geladenen Schaltkreis und an einen negativ geladenen Schaltkreis zu denken. Je ein Befestigungselement 10 verbindet jeweils einen der Schaltkreise. Nach der Montage des Deckels 3 an dem Gehäuse 1 mit Hilfe von einem oder mehreren Befestigungselementen 10 wird die Ausnehmung 8 mit einer elektrisch isolierenden Vergußmasse 20 versehen, so daß der Schraubenkopf 11 gegenüber der Umgebung elektrisch isoliert ist. Daraus ergibt sich ferner der Vorteil, daß die Anordnung nicht mehr unbefugt geöffnet werden kann, weil zum Demontieren oder Montieren benötigte Schlüsselflächen 21 nicht mehr unmittelbar zugänglich sind. It should be noted that a plurality of mutually associated conductor elements 2, 4 can also be arranged in the housing 1 and the cover 3, which are connected to one another in the manner described above. In particular, a positively charged circuit and a negatively charged circuit should be considered. One fastening element 10 connects one of the circuits. After mounting the cover 3 on the housing 1 with the aid of one or more fastening elements 10, the recess 8 is provided with an electrically insulating casting compound 20, so that the screw head 11 is electrically insulated from the surroundings. This also has the advantage that the arrangement can no longer be opened without authorization because key surfaces 21 required for disassembly or assembly are no longer directly accessible.
