Description

Technical Field

[0001] The present application relates to the technical field of collector rings, and in particular to a novel metal silver-plated collector ring. Background Art

[0002] Collector rings are also called conductive rings, slip rings, collector rings, and confluence rings. They can be used in any electromechanical system that requires continuous rotation while transmitting power and signals from a fixed position to a rotating position. The material of the collector ring requires high mechanical strength and is a good conductor of electricity. It must also be corrosion-resistant. When in sliding contact with the brush, it must have wear resistance and stable sliding contact characteristics. Metal silver-plated collector rings meet this requirement.

[0003] Patent No. CN220172551U discloses a metal silver-plated collector ring, which is provided with a connecting shaft, a silver-plated sleeve ring structure, a sleeve ring fixing structure and a copper ring. First, the connecting shaft splices multiple copper rings with the silver-plated sleeve ring, and the first conductive rod and the second conductive rod connect the copper rings of different groups to achieve the switching function when the brush contacts it. At the same time, the silver-plated sleeve ring structure sleeves the copper ring to achieve the contact between the brush and the silver-plated ring, thereby improving the conductivity. The inner arc plate inside the sleeve ring can abut against the copper ring, and the structure is stable. The sleeve ring fixing mechanism is convenient for disassembly and replacement of the silver-plated ring. When replacing, only the silver-plated ring needs to be replaced, which is convenient to operate and reduces costs. However, the collector ring cannot achieve the purpose of stabilizing the position of the copper ring in different use environments by only abutting the inner arc plate with the copper ring. When the collector ring is inverted or tilted, the copper ring may be out of the restriction of the inner arc plate. Utility Model Content
