technical field

Background technique

The conductive ring assembly is the rotor assembly in the conductive slip ring, which is in sliding contact with the brush wire to realize the transmission of various electrical signals within the range of relative rotation of 360°. The conductive ring assembly is generally composed of a conductive ring and an insulating ring welded with wires. The rings and insulating rings are installed at intervals, and there are certain insulation performance requirements between the conductive rings, and no open circuit or increased resistance is allowed after the wire and the conductive ring are welded.

Highly integrated conductive ring components are stacked and cast as a whole, and processed as a whole. The structural form may cause disconnection between some conductive rings and wires after processing, or the insulation resistance between some adjacent conductive rings may decrease.

One end of the conductive ring assembly is a bare conductive ring and the other end is a wire. Generally, a digital multimeter is used for the continuity test, but for a conductive ring assembly with a high degree of integration, the efficiency of the digital multimeter test is not only low, but also the error rate is high. ; Generally, an insulation meter or a shaker is used to test the insulation resistance. The insulation meter or shaker can only test the insulation resistance between two conductive rings at a time, and then test in turn. It takes 1.5 hours to test the continuity and insulation of the multi-channel conductive ring assembly, and it needs 2 people to operate at the same time, which is inefficient.
