With the slip rings in more and more high-end areas such as : satellite , aerospace , deep-sea exploration, intelligent robots and other fields widely used material for electrical contact applications and requirements are higher. Especially in the satellite- based aerospace technology practical application of some special requirements, vacuum environment , high and low temperature characteristics , ultra-long maintenance free operation and other harsh conditions , however, these requirements do not use some kind of special theory make a clear analysis on the current level of technology , many studies have not achieved completely and control theory to reveal some of the inherent laws of science .

Technically speaking, the slip ring is a sophisticated , complex wiring connecting parts , precision slip ring 's role is to achieve equipment operation part and the fixed part of the force , the signal transmission. As the rotation of the transmission , the slip ring is the basic structure of a rotating rotor and a fixed stator components.

In practical application process, some very demanding work environment requires several years of continuous work , which for the wiper material requirements are very high . Separate usually consists of a slip ring slip ring brush holder and matching components , separate slip ring rotor and the contact brush set is to solve the issue of limiting the size of the installation was the best ideal solution . It is based on the customer's line needs to arrange the wiring , the use of customers' existing bearing system to achieve the height restrictions in demanding power and stability of the signal transmission.

Precision slip ring with real experimental testing materials and equipment reliability under special circumstances , or as the main research basis . To meet separate slip ring in the real application requirements, you need to have a working brush and slip ring slip ring performance evaluation system for the reliability evaluation. So in a variety of special circumstances , affect the slip ring electrical connector key performance indicators to analyze the factors and reasonable improvement , including the formulation of materials , processing technology , design and other aspects of the comprehensive evaluation of the structure . What kind of results have better electrical contact material wear resistance , electrical conductivity , durability, brush and collector ring how much pressure is the most appropriate , both to meet the electrical conductivity and can wear at least , what kind of performance satellites, spacecraft, in order to meet the slip ring contacts and service life and reliability requirements.
