More Information
Summary:A contact piece 12 for a current collector 11 for transmitting energy from a conductor rail to a vehicle comprises: a contact shoe 17 that forms a sliding contact with a conductor rail; and a connecting bar 19 that is connected to a connecting device 13 that holds and electrically connects the contact piece to a current collector. A connecting end 21 of the connecting bar can be inserted into a contact piece receiver 23 of the connecting device. The connecting end comprises a connecting cross section 22 having an insertion contour, which is asymmetric in relation to the connecting cross section, for detachably connecting to the contact piece receiver. The asymmetric insertion contour may be formed by extensions 34, 35 which vary in thickness and prevent a faulty installation of the contact piece at the contact piece receiver. The connecting bar has a material weakening which forms a predetermined breaking point 44 which breaks when an impact acts on the contact piece or when there are large obstacles on the conductor rail which could lead to deformation of the contact piece.
