Title:
SLIP RING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/039084
Kind Code:
A1
Abstract:
This slip ring device is provided with a rotary shaft 14, electrically conductive rings 22, and a pair of contactors 16. The rings 22 are provided to the rotary shaft 14. The pair of contactors 16 are in contact with the rings 22. The pair of contactors 16 each have one end provided to a substrate 15, and another end in contact with the rings 22. When W1 represents the distance between the one ends of the pair of contactors 16, L represents the distance from the one ends of the pair of contactors 16 to contact points where the other ends of the pair of contactors 16 are in contact with the rings 22, and W2 represents the distance between the contact points, the relationship between W1, W2, and L satisfies W1:W2:L=1:1.41-4.60:1.67-5.22. Accordingly, the slip ring device is capable of reliably reducing noise.
