By the way, since the connecting pin 1 is loosely inserted into the long hole 3, the connecting pin 1 does not reliably contact the movable conductor 2, and when the floating pin is in a floating state, the connecting pin 1 has an intermediate potential with respect to the potential of the movable conductor 2. And a corona discharge is generated in a minute gap between the movable conductor 2 and the connecting pin 1, which causes insulation deterioration.
During energization, it causes abnormal noise and vibration.
