Description

Die Erfindung bezieht sich auf eine elektrische Verbindungsvorrichtung gemäß Oberbegriff des Anspruchs 1; eine derartige elektrische Verbindungsvorrichtung ist aus der DE-A-22 30 806 bekannt.The invention relates to an electrical connection device according to the preamble of claim 1; such an electrical connection device is known from DE-A-22 30 806.

Im bekannten Fall sind an einer in einem Lagerbügel eines Kollektor-Motors verrastbaren Kunststoffbrücke an gegenüberliegenden Seiten des Kollektors in einem Wickelstützpunkt je eine Lötfahne zum Anschluß einer Bürstenlitze durch die Kunststoffbrücke durchgesteckt und an ihrem anderen durchgesteckten Ende mit einem Flachstecker oder einer Steckhülse für eine korrespondierende Steckhülse oder einen korrespondierenden Flachstecker einer anzuschließenden äußeren Anschlußleitung ausgebildet.In the known case, a soldering lug for connecting a brush wire is inserted through the plastic bridge on a plastic bridge which can be locked in a bearing bracket of a collector motor on opposite sides of the collector in a winding base and at its other inserted end with a flat plug or a receptacle for a corresponding receptacle or a corresponding tab connector of an external connecting cable to be connected.

Gemäß Aufgabe vorliegender Erfindung soll eine einfache, mit wenigen Bauteilen erzielbare und in für eine automatisierbare Fertigung vorteilhafter Weise mit nur einer Haupt-Handhabungsrichtung montierbare elektrische Verbindung zwischen den Enden einer Wicklung und einem Metall-Kontaktelement unter Einbezug eines Wickelstützpunktes geschaffen werden.According to the object of the present invention, a simple electrical connection between the ends of a winding and a metal contact element with the inclusion of a winding support point, which can be achieved with only a few components and can be assembled advantageously for automated production with only one main handling direction, is to be created.

Die Lösung dieser Aufgebe gelingt bei einer elektrischen Verbindungsvorrichtung der eingengs genannten Art durch die Lehre des Anspruchs 1; vorteilhafte Ausgestaltungen der Erfindung sind jeweils Gegenstand der Unteransprüche. Bei der erfindungsgemäßen Vorrichtung kann durch einfaches Aufstecken eines Metall-Kontaktelementes in Richtung der Wickelachse des um den Kunststoff-Zapfen umwickelten Wicklungsdrahtes einerseits eine elektrische Kontaktierung zwischen dem Kontaktelement und dem Wickeldraht an mehreren Kontaktstellen und gleichzeitig eine Fixierung des Kontaktelementes am Wickelstützpunkt erreicht werden; eine besonders gute elektrische Kontaktierung, insbesondere bei einem mit einem Isolierlack überzogenen Wickeldraht, ergibt sich dadurch, daß einerseits der Kunststoff-Zapfen mehrfach schraubenförmig von dem Wickeldraht umschlungen ist und andererseits die Gabel-Flanken an ihren Berührungsflächen mit den umschlungenen Wickeldraht mit dessen Isolierung beim Aufstecken des Metall-Kontaktelementes durchstoßenden scharfen Kanten versehen sind.These tasks are solved in an electrical connection device of the type mentioned by the teaching of claim 1; advantageous embodiments of the invention are the subject of the dependent claims. In the device according to the invention, by simply plugging on a metal contact element in the direction of the winding axis of the winding wire wrapped around the plastic pin, electrical contacting between the contact element and the winding wire can be achieved at several contact points and at the same time the contact element can be fixed at the winding base; A particularly good electrical contact, in particular in the case of a winding wire covered with an insulating varnish, results from the fact that, on the one hand, the plastic pin is wrapped several times in a helical shape by the winding wire and, on the other hand, the fork flanks at their contact surfaces with the wrapped winding wire with its insulation when plugged on of the metal contact element piercing sharp edges.

Die beim Aufstecken des Metall-Kontaktelementes selbsttätig sich einstellende Kontaktierung mit dem Wickeldraht und eine mechanische Fixierung des Metall-Kontaktelementes an dem Wickelstützpunkt bei Erreichen seiner End-Aufsteckstellung wird dadurch wesentlich erleichtert, daß nach einer Ausgestaltung der Erfindung der Kunststoff-Zapfen mit einem beim Aufstecken des Metall-Kontaktelementes die Gabel-Flanken gegen den umschlungenen Wickeldraht andrückenden Spreizkegel-Fläche versehen bzw. die Gabel-Flanken in ihrer auf den Kunststoff-Zapfen aufgesteckten End-Aufsteckstellung außerhalb ihrer Kontaktfläche in dem aus einem im Vergleich zum Metall-Kontaktelement weicheren Material bestehenden Kunststoff-Zapfen verkrallt und/oder verrastet sind.The contacting with the winding wire that occurs automatically when the metal contact element is plugged in and a mechanical fixation of the metal contact element on the winding base when it reaches its end plug-on position is considerably facilitated in that, according to one embodiment of the invention, the plastic pin with a when plugging in of the metal contact element provide the fork flanks against the conical surface pressing against the wrapped winding wire, or the fork flanks in their end plug-on position plugged onto the plastic spigot outside of their contact surface in a material which is softer than the metal contact element Plastic pins are clawed and / or locked.

Nach einer weiteren Ausgestaltung der Erfindung ist der Kunststoff-Zapfen mit jeweils einer aufsteckseitig offenen ersten Führungsöffnung für das Aufsteckende des Metall-Kontaktelementes und einen zweiten, die erste Führungsöffnung kreuzenden schlitzförmigen Führungsöffnung zum Einlegen und/oder Fixieren eines Wicklungsendes des Wickeldrahtes versehen.According to a further embodiment of the invention, the plastic pin is provided with a first guide opening, which is open on the plug-in side, for the push-on end of the metal contact element and a second, slot-shaped guide opening, which crosses the first guide opening, for inserting and / or fixing a winding end of the winding wire.
