A Conductive Slip Ring is a device used to transmit electrical energy, signals and data, and is often used in rotating systems or mechanical devices. Its working principle is to transfer current or signal from the fixed part to the rotating part through sliding contact, so that the electrical connection can be maintained between the two.
A slip ring usually consists of two main parts: a stationary ring (also known as a base or stationary ring) and a rotating ring (also known as a rotor or slip ring). The fixed ring is fixed to the stationary part, while the rotating ring is connected to the rotating part. The two rings are in contact with each other through a set of conductive brushes (also called brush blocks), which are made of conductive material. When working, the current or signal enters the brush block through the conductive path of the fixed ring, and then transmits to the rotating part through the contact between the brush block and the rotating ring. Conductive paths on the rotating ring carry current or signals to the desired device or component. During transmission, the brush blocks remain in contact with the rotating ring to ensure continuity of the electrical connection. The design and manufacture of conductive slip ring need to consider the following key factors: Conductivity: The conductive material of the slip ring must have good conductivity to ensure the effective transmission of current or signals. Commonly used conductive materials include copper, silver, and gold. Wear and Friction: Since slip rings work by sliding contact, wear and friction are unavoidable. In order to reduce wear and friction, slip rings are usually made of low-friction materials and properly lubricated. Life and reliability: Slip rings need to have sufficient life and reliability to meet the needs of practical applications. This includes sound design, quality materials and reliable manufacturing. Signal interference: When transmitting signals, slip rings may experience electromagnetic interference from rotating parts. In order to reduce signal interference, slip rings usually use shielding and isolation techniques. Conductive slip rings are widely used in various fields, such as rotating machinery, robots, stage lighting, medical equipment and radar systems, etc. They provide a convenient way of power and signal transmission for the rotating system, enabling the rotating part to communicate and transfer energy with the fixed part flexibly and reliably.
