The Classification and Application of Slip Ring

Slip ring is the center conduction of connecting ring and the outer of lead wire as a shield ring. Transmission of more than 12MHz signal ususally uses coaxial lines of Shielded slip ring--Coax Rotary Joint, the cross section of this kind of slip ring like a trough shape, actually it is rectangular coaxial conductor. Also there is a kind of capactive intermediate frequency slip ring, which has a circular center conductor with using insulation to support shielding layer. Intermediate frequency slip ring is a kind of component that could be used to transmit radar intermediate-frequency ( tens of Megahertz ) signal and power. This type of slip ring enjoys high frequency, transferring below 12MHz frequency can use ordinary slip ring, say capsule slip ring with different diameter.

Low frequency slip ring takes advantage of contacting to transmit low frequency signal and power. For example, one of the type of cylindrical slip ring which of conduction ring can be divided into flat and V-shaped ring. Conductive ring materials normally use red copper, brass, silver and gold and the brush materials adopt palladium alloy, hexabasic alloy, gold to gold plated or copper graphite brush.

The electrical indicators of slip ring are: insulation resistance, contacting resistance, dielectric strength and electrical noise. For intermediate frequency slip ring which should consider shielding, impedance matching, noise, voltage and so on because of high frequency. Making sure reliable contacting and all lines contacted in a row on the structure designing process. Therefore, brush materials should have good conduction performance, good grinding, low friction torque with easy maintenance.

The structure types of cylindrical slip ring as per installation request can be divided into shaft and through hole slip ring. Which important technical specifications need to provided when choose slip ring? 1. Circuits 2. Current and Voltage 3. Work speed 4. Work temperature 5. Dimension 6. IP degree.

Does conductive slip ring has signal resistance measure?
Answer: Slip ring enjoys compact structure and design which can pass various digital and analog signal with using gold to gold contact materials. From the current technology on the structure design, slip ring could completely avoid interference problem between power and signal or signal between signal, also can prevent outside electromagnetic interference to the inside of slip ring.

How many signals that slip ring could transfer?
Answer: Now slip ring can transmit all low and medium frequency signal, CAN bus signal etc. For example, Inter Bus, Can Bus, Profibus, RS422, RS485, PLC cotrol, analog video, digital audio, gigabit Ethernet, sensor signal and so on.

Nowadays, slip ring are widely applied in the field of national defense military, such as reconnaissance aircraft equipment and air defense radar artillery system, early warning and antenna and the missile test system.
