Abstract

In un portaspazzole (17) per macchine a corrente continua una piastra (18), portante le spazzole (23, 24), è fissata, con disaccoppiamento dei rumori, ad una staffa di sostegno (20) da collegare con la cassa (10) della macchina. L'attacco elettrico avviene tramite un connettore a innesto (34), sostenuto sulla piastra (18) delle spazzole, e tramite una linea di massa (35) che da un punto di sostegno (33) di brasatura sulla piastra (18) delle spazzole porta alla staffa di sostegno (20). Per migliorare il disaccoppiamento dei rumori del portaspazzole (17) la linea di massa (35) è eseguita flessibile ed è fatta preferibilmente di due staffe di contatto rigide (36 e 37) e di una trecciola (38) flessibile, di conduzione della corrente, collegante fra di loro le due staffe di contatto (36) e (37) La prima staffa di contatto (36) è fissata al primo punto di sostegno di brasatura (37) mentre la seconda staffa di contatto (37) è fissata alla staffa di sostegno (20) (Figura 2).In a brush holder (17) for direct current machines a plate (18), carrying the brushes (23, 24), is fixed, with noise decoupling, to a support bracket (20) to be connected with the casing (10) of the car. The electrical connection is via a plug connector (34), supported on the plate (18) of the brushes, and via a ground line (35) which from a brazing support point (33) on the plate (18) of the brushes leads to the support bracket (20). To improve the decoupling of the noises of the brush holder (17), the ground line (35) is made flexible and is preferably made of two rigid contact brackets (36 and 37) and a flexible, current-carrying braid (38), connecting the two contact brackets (36) and (37) together. The first contact bracket (36) is fixed to the first brazing support point (37) while the second contact bracket (37) is fixed to the support (20) (Figure 2).
