The invention discloses a conductive slip ring with a multi-groove multi-wire structure and a method for realizing the long service life of the conductive slip ring. A first ring piece has a two-groove structure, and a second ring piece has a three-groove structure; each ring piece groove is a V-shaped groove, and each ring piece groove can accommodate a one brush wire; when the conductive slip ring is in operation, a ring body assembly rotates, a brush assembly is fixed, and the brush wires and the first ring piece and the second ring piece are relatively rotated. It is possible to transmit an electrical signal from an input end to an output end through the brush wires. The brush wires are improved from a single brush wire to a multi-brush-wire, the first ring piece can accommodate two brush wires, and the second ring piece can accommodate three brush wires, and in this way, the problem that the service life of the conductive slip ring is affected by worn brush wires during working ofthe conductive slip ring can be avoided, and the long service life of the conductive slip ring can be realized. The invention can enable a single ring piece to contact a plurality of brush wires at the same time, thereby effectively improving the stability of the signal transmission of the conductive slip ring and prolong the service life.
Description
technical field [0001] The invention relates to the technical field of conductive slip rings, in particular to a conductive slip ring with a multi-groove and multi-wire structure and a method for realizing long service life of the conductive slip ring. Background technique [0002] The conductive slip ring is a key component of the electrical signal transmission device. The contact mode and stability of the ring body of the conductive slip ring and the brush wire directly affect the stability and service life of the electrical signal transmission of the conductive slip ring. At present, most conductive slip rings use a single-slot single-filament structure to realize electrical signal transmission, and the signal transmission of the single-slot single-filament structure all depends on a single brush wire, and the brush wire of the conductive slip ring will be worn to a certain extent during the working process. , that will definitely affect the service life of the conductive...
