Abstract
A current collector supplies power to an electrical load movable along a conductor line and includes a movable holder for a contact element whose range of movement is restricted by two mechanical stops, and which is acted upon by a spring arrangement exerting a force in the direction of a first end of its range of movement to force the contact element against a power rail. A damping device is provided, which dampens movement of the holder caused by the spring arrangement in the direction of the first end of its range of movement, when the holder is situated within a predetermined first section of its range of movement, which is restricted on one side by the first end and does not include the entire range of movement. The damping device can be designed as a flow damper or a friction damper or as at least one spring element.

A current collector for power supply to an electrical load movable along a conductor line, the current collector comprising:
- a movable holder for a contact element, whose range of movement is restricted by two mechanical stops and which is acted upon by a spring arrangement exerting a force in the direction of a first end of a range of movement so as to force the contact element against a power rail;
- and
- a damping device which dampens movement of the holder caused by the spring arrangement in the direction of the first end of the range of movement, when the holder is situated within a predetermined first section of the range of movement, which is restricted on one side by the first end and does not include the entire range of movement,
- wherein a second section is adjoining the predetermined first section of the range of movement of the holder
- wherein a third section is adjoining the second section, the third section extending to a second end of the range of movement that is opposite the first end of the range of movement, and
- wherein stiffness of the spring arrangement in the third section is less than in the second section.
A current collector for power supply to an electrical load movable along a conductor line, with a movable holder for a contact element, whose range of movement is restricted by two mechanical stops and which is acted upon by a spring arrangement exerting a force in the direction of a first end of a range of movement so as to force the contact element against a power rail,
- wherein a damping device is provided, which dampens movement of the holder caused by the spring arrangement in the direction of the first end of the range of movement, when the holder is situated within a predetermined first section of the range of movement, which is restricted on one side by the first end and does not include the entire range of movement,
- wherein a second section is connected to the predetermined first section of the range of movement of the holder and a third section is connected thereto, the third section extending to a second end of the range of movement opposite the first,
- wherein stiffness of the spring arrangement in the third section is less than in the second section, and
- wherein the spring arrangement has at least two springs mechanically connected parallel to each other, at least one of which is active over the entire range of movement of the holder and at least one of which is active in the second section of the range of movement of the holder and inactive in the third section.
