Abstract

Die Erfindung bezieht sich auf eine Bürstenhalterung (10) für eine Kohlebürste (12) umfassend ein einseitig offenes quader- oder köcherförmiges Gehäuse (14), in dem die Kohlebürste mittels eines auf diese einwirkenden Federelements (16) axial verschiebbar ist, wobei von der Kohlebürste ein elektrischer Leiter wie Litze (20) ausgeht, der mit dem Gehäuse in dessen rückseitiger Stirnwandung (22) verbunden wie verschweißt ist. Um eine sichere Verbindung zwischen dem Leiter und dem Gehäuse bei gleichzeitiger Reduzierung der Länge des Leiters sicherzustellen, wird vorgeschlagen, dass der elektrische Leiter von einem sich in oder in etwa in Längsrichtung des Gehäuses erstreckenden Abschnitt (26) der rückseitigen Stirnwandung ausgeht.

Figure 00000001
The invention relates to a brush holder (10) for a carbon brush (12) comprising a cuboid or quiver-shaped housing (14) which is open on one side and in which the carbon brush is axially displaceable by means of a spring element (16) acting on it, whereby the carbon brush an electrical conductor such as a strand (20) emerges, which is connected to the housing in its rear end wall (22) as welded. In order to ensure a secure connection between the conductor and the housing while simultaneously reducing the length of the conductor, it is proposed that the electrical conductor start from a section (26) of the rear end wall that extends in or approximately in the longitudinal direction of the housing.
