Technical Field

The invention relates to the field of slip rings, in particular to a compact slip ring.

Background

The slip ring is also called a conducting ring, a collecting ring, a conducting slip ring, an electric brush, a rotary joint, a rotary electric joint and the like, and is widely applied to security protection, wind power generation, factory automation, electric power, finance, instruments, chemical engineering, metallurgy, medical treatment, aviation, military, ships, transportation, buildings and other electromechanical equipment. Slip rings there are basic classes of precision instrumentation slip rings: according to different devices, the requirements on the slip ring in the aspects of size, appearance structure, speed, frequency, transmission signals and the like are high; industrial conductive slip ring: most of the slip rings are slip rings, the size is large, and the requirements on temperature and service life are high; military slip rings: explosion-proof and earthquake-proof requirements are high; marine vessel slip rings: the requirements on water resistance and corrosion resistance are high; wind wheel slip ring: the protection level is higher, mostly is the hollow shaft, and a small number is cap formula sliding ring. The conducting ring can improve the system performance, simplify the system structure and avoid the wire from being twisted due to the rotation of the movable joint.

The existing slip ring is large in size, and the brush wires are easy to wear and need to be replaced frequently.

An effective solution to the problems in the related art has not been proposed yet.
