<p>Break warning device for a sliding connector (1), which is permanently anchored to a carrier (2), of a current collector device. The sliding connector (1) has in the direction of its longitudinal extent in the half facing the carrier (2) of the sliding connector a groove (3) or hole (4) into which a signal rod (5) which breaks brittlely is fitted. On one of its sides, the signal rod (5) is secured in an unmovable holder (23) and a holding device (14) with a movable holding element (7; 8) engages on the other side, the said holding device subjecting the rod (5) to tensile stress. When the sliding connector (1) breaks, the signal rod (5) also breaks. As a result of the tensile force acting on it, the residual part of the signal rod (5) which is connected to the movable holding element (7; 8) moves in the direction of the resultant of the forces and, in this process or after it makes contact with a switching element (15), triggers a damage-limiting process. <IMAGE></p> |
