Slip ring sliding electrical contacts are connected application areas, it is also known as the collecting ring, or rotary joints, rotary electrical interface, slip rings, collector rings, return ring, coil, commutator, adapters, is to achieve two a relative rotation body image, the data signal and power transmission and other precision products. Particularly suitable for unrestricted continuous rotation, at the same time need to rotate the location from a fixed location or data transmission power and other places. 
 Its made of elastic materials (ie, conductive brush), sliding contact surface materials (ie, conductive ring), insulation materials, bonding materials, composite frame, precision bearings, dust cover and other auxiliary parts and other components. Brush with conductive materials, precious metal alloys, was character-type and the conductive ring groove symmetrical double exposure, with the brush of conductive ring elastic pressure and a slot to pass signals and current contacts. 
 Precision slip ring of high-tech products, has long been used in advanced military field, reconnaissance aircraft equipment, air defense radars, artillery systems, early warning antenna, a key missile test system accessory products. As the economy continues to develop, more and more civil applications involved the use of such products for industrial automated system control. These products have been moved from the military into civilian products products are widely used in security, factory automation, power, finance, instrument, aviation, military, transportation, construction and electrical equipment.
