Slip rings are important electrical components responsible for connecting and transmitting energy and signals for rotating bodies. According to the transmission medium, slip rings are divided into electric slip rings, fluid slip rings, and smooth rings. It can also be commonly referred to as "rotational connection" or "rotational connection".

The slip ring is usually installed in the center of rotation of the equipment, mainly composed of two parts: rotating and stationary. The rotating part is connected to the rotating structure of the device and rotates with it, which is called the "rotor", and the stationary part is connected to the fixed structure of the device, which is called the "stator". The slip ring as a whole depends on the elastic lap principle, rolling lap principle, or sealing principle, as well as ingenious motion structure and seal structure design, precision parts production and cooperation, reasonable material selection, etc., to form a stable and reliable rotary communication system. As long as the slip ring is attached to the infinitely rotating equipment, it can provide power energy to the rotating body, so that the rotating body can perform other movements at the same time as the infinite rotating motion, or detect the working condition in the rotating state.

The traditional electric slip ring is also called "collector ring" or "bus ring". Several decades ago, there were mature design technologies and mature production plants in China, which mainly transmit large currents and adopt the technology of carbon brushes close to the copper ring. Disadvantages: limited to the transmission of a large amount of carbon alloy powder due to friction, which requires periodic cleaning or replacement of carbon brushes. Due to the rapid development of modern precision electronics and precision electromechanical products, precision electric slip rings came into being. It was originally dedicated to ultra-high-end fields such as aviation and aerospace. Now it is widely used in civilian precision electronic and electrical equipment. Some series have been made into general electrical accessories.

Electric slip rings, the most widely used in all slip ring series, also known as brushes, carbon brushes, collector rings, collector rings, collector rings, rotary through, rotating electrical joints, are designed for transmission during unlimited continuous rotation Power supply, signal power supply. The stator and rotor parts lead wires to connect the power supply and terminal appliances of the fixed structure and the rotating structure, respectively, and rotate accordingly. According to the difference of its overall structure, it is divided into solid round slip ring (dig a hole in the rotating body and install the slip ring), empty round slip ring (install the slip ring on the rotating shaft), and separate slip ring, flat disc slip ring, Mercury slip ring, special slip ring, etc.

Slip rings are mostly used in high-end industrial electrical equipment or precision electronic equipment with multi-function, high performance, high precision, and multiple continuous rotation power, such as: aerospace equipment, radar communication equipment, medical equipment, automatic processing equipment, smelting equipment , Mining equipment, cable equipment, amusement equipment, display equipment, smart cameras, chemical reactors, crystal furnaces, wire stranding machines, windmills, robotic arms, robots, shield machines, revolving doors, measuring instruments, model aircraft, special vehicles, Special ships, etc. Slip rings provide reliable energy and signal transmission solutions for these electromechanical devices to achieve complex movements. It can also be said that slip ring is a sign of advanced intelligent sports equipment.

JARCH slip ring can also be made into various special shapes according to the usage, mixed transmission power source, light source, fluid pressure source, or used in conjunction with other electrical components, such as: special shaped, super large shape, connected gear, sprocket, Belt pulley, plug, power supply and light source are mixed, power supply and pressure fluid are mixed, equipped with light, electricity, sound, temperature sensor, optical fiber transceiver, pressure gauge, pneumatic components, etc., combined into a multi-functional electrical parts assembly to achieve Special requirements to save space and simplify design structure.
