Description

Technical Field

[0001] The utility model relates to the technical field of slip rings, in particular to a mercury-substituting slip ring structure. Background Art

[0002] Mercury slip rings are widely used in automation equipment such as electroplating assembly line equipment and lightning arresters. Mercury slip rings are mechanical seal structures, and their contacts are composed of mercury. During operation, the mercury slip ring will have a temperature rise when passing through a large current load, which can cause the mercury slip ring to volatilize faster. Therefore, existing mercury slip rings have the disadvantages of being volatile, not environmentally friendly, highly toxic, not resistant to high temperatures, and having a short lifespan.
