Description

Technical Field

[0001] The invention relates to the technical field of conductive devices, and in particular to a conductive ring suitable for assembly and a motor assembly. Background Art

[0002] Conductive ring (also called slip ring) is a device for power and signal transmission, widely used in systems that require rotating connections. Its main function is to allow the transmission of current and signals between stationary and rotating parts, thereby ensuring the normal operation of the equipment. As a key component connecting stationary and rotating parts, conductive ring plays an important role in many high-tech fields.

[0003] The conductive fiber of the existing conductive ring is inside the ring and contacts the rotating part, and the conductive ring body contacts the stationary part, and the conductive ring is a stationary part. The existing conductive ring will generate wind resistance due to the high-speed operation of the rotating shaft surface, and the conductive fiber will be subject to resistance. The actual number of fibers in effective contact will be lower than the design value, resulting in a decrease in the conductivity of the conductive ring. After working for a period of time, due to the deformation of the conductive fiber, the number of fibers in effective contact will further decrease, causing the conductivity of the conductive ring to further decrease. In order to ensure the long-term effective conductivity of the conductive ring, the interference between the conductive fiber and the rotating shaft and the number of fibers can be increased, but this will cause increased wear and increased costs. Summary of the invention
