Description

technical field [0001] The invention belongs to the technical field of rotary connectors, in particular to a rotary connector for mixed transmission of wireless power and data. Background technique [0002] With the advent of the 5G era, the existing rotary connectors can no longer keep up with the growing demand. Modern industrial scenarios require faster and more reliable power and data transmission between rotating parts. As this demand grows, so do the bandwidth, crosstalk and EMI performance requirements of data interfaces used in rotary joints. Meeting these requirements is crucial to guarantee real-time operation, continuous uptime and maximum efficiency of the corresponding industrial equipment. In the military, as the equipment is updated, the rotation speed of the rotary connector is required to be higher and higher, the life is longer, and the transmission rate is gradually increased to Gbps. At present, traditional rotary connectors have obvious shortcomings: 1...

AI Technical Summary

Problems solved by technology

At present, traditional rotary connectors have obvious shortcomings: 1. The use scenarios of pure wireless data transmission and pure wireless power transmission are limited to a certain extent. At present, there is no wireless power data hybrid transmission rotary connector on the market

Due to the influence of the internal structure of the rotary connector, it is large in size and high in weight, which limits many usage scenarios; 3. Low data transmission rate

When the brush wire and slip ring rotate at high speed, the contact point impedance discontinuity will lead to data loss; 4. Low life

Contact friction between brush wire and slip ring, resulting in contact wear; 5. Poor reliability

The contact friction between the brush wire and the slip ring will cause contact sparks and affect the transmission reliability; 6. It cannot be rotated at high speed for transmission

When rotating at high speed, there will be continuous contact sparks in power transmission, which is extremely unsafe; when rotating at high speed for data transmission, the contact impedance is discontinuous, and high-speed signals cannot be transmitted
