[0002] The conductive contact finger is a very important conductive element in the high-voltage circuit breaker. The conductive contact finger includes an inner wall surface for conductive contact with the conductive rod and an outer wall surface far away from the inner wall surface. The wall surface is an arc-shaped outer arc surface, which also includes two sides connected between the inner wall surface and the outer wall surface. In order to ensure that adjacent conductive contacts can rotate freely, the intersection line of the two sides does not pass through the inner arc surface And the center of the outer arc surface, in order to ensure good contact and conduction between the conductive contact finger and the conductive rod, generally the conductive contact finger needs to detect the inner arc surface and the outer arc surface of the conductive contact finger to the center line of the arc before use distance, but the center line of the arc is the spatial position, and positioning and measurement are very difficult, so three-coordinate measurement is generally used for detection, but because the detection of conductive contacts is very frequent, and the three-coordinate measuring instrument is expensive and the maintenance cost is high, Therefore, the use of a three-coordinate measuring instrument not only takes up a lot of time for the three-coordinate measuring instrument, but also increases the detection cost
