Waterproof Slip Ring is a commonly used rotary interface, usually used in occasions that need to transmit power, signal, data and other signals, such as industrial machinery, medical equipment, cameras and so on. Its principle is similar to the traditional slip ring, but the waterproof and dustproof features are added to the design to adapt to the harsher working environment.
The principle of waterproof slip ring is mainly based on the working principle of brushes and collector rings. In traditional slip rings, brushes contact slip rings and transmit signals through friction, but such designs are not suitable for wet, dusty environments. In order to solve this problem, the waterproof slip ring adopts a sealed structure, and at the same time adopts new materials and designs to make it have better waterproof performance. The structure of the waterproof slip ring generally consists of a fixed part and a rotating part. The fixed part includes casing, cable interface and connector, etc., and the rotating part includes rotor, slip ring and brush, etc. When the rotating part starts to turn, the collector ring starts to transmit the signal, and at the same time, the gap between the brush and the collector ring is sealed to ensure waterproof performance. The sealing performance of the waterproof slip ring Conductive Slip Ring mainly depends on two methods: mechanical seal and structural seal. The mechanical seal mainly adopts spring-type seal and air-tight seal, etc., through the action of elastic force and gas, the gap between the brush and the collector ring is sealed to ensure waterproof performance. Structural sealing mainly uses materials such as O-shaped sealing ring and sealing oil to form a sealing layer between the brush and the collector ring to prevent the intrusion of sundries such as water and dust. In general, the principle of the waterproof slip ring is based on the traditional slip ring, adding a waterproof and dustproof design, while using new materials and sealing structures to adapt to harsher working environments.
