Embodiment Construction

[0060] figure 1 A schematic side view of a sliding contact 1 comprising an electrical wire 2 according to the invention is shown. The wire 2 is solidly formed from a copper-silver alloy or contains a core made of this alloy and is coated with a gold alloy on the sheath side. The copper-silver alloy conducts electricity and makes the electric wire 2 sufficiently elastic.

[0061] The electric wire 2 is fixed on the device 4 through the fixing part 3 . The device 4 may be any device, such as a mast of a wind generator or a component fixedly combined with a mast of a wind generator. A suspension frame 5 fixedly combined with the device 4 is provided on the device 4 . The roller 6 is mounted in the suspension 5 as a stationary contact rotatably about an axis 7 with respect to the wire 2 . In addition, the roller 6 has an electrically conductive surface and is cylindrically formed. The axis 7 is at the same time the axis of symmetry of the cylindrical drum 6 . The drum 6 is n...

Abstract

The invention relates to a wire for producing a sliding contact, wherein at least an inner core of the wire comprises a copper / silver alloy. The invention also relates to a sliding contact with at least one such wire, wherein a mating contact is provided, with at least one of the wires resting on the conductive surface of said mating contact, wherein the spring force of the wire on the conductive surface of the mating contact brings about electrical contact between the wire and the mating contact, and the mating contact is moveable towards the wire, with the result that the surface of the wire slides over the mating contact during a movement of the mating contact. Finally, the invention also relates to a potentiometric sensor, a potentiometer, a sliding controller, a position sensor, a rotary switch, an electric motor, a generator, a wind turbine, a slip ring system, a servo drive or a current collector with such a sliding contact.

Description

technical field [0001] The invention relates to an electrical wire for the manufacture of sliding contacts. The invention also relates to a sliding contact comprising such a wire. [0002] Finally the invention also relates to potentiometric sensors, potentiometers, slide controls, position sensors, rotary switches, electric motors, generators, wind turbines, slip ring systems, servo motors or current collectors comprising such sliding contacts. Background technique [0003] The wires of the sliding contacts and the sliding contacts themselves have a variety of applications when it is necessary to transfer electrical current to moving parts. Sheathing wires comprising an inner core wire made of a first metal or a first metal alloy and an outer sheath or coating made of a second metal or a second metal alloy are also used for this purpose. Such sheathed wires are used, for example, as sliding contacts in slip ring transmission systems. The sliding contacts are used to tran...
