Abstract
A rotary connector includes a stationary housing, a rotative housing, a rotative holder, floating spacers, and flat cables. The flat cables provide a low-current path to a steering wheel of a vehicle. The rotary connector also includes a slip ring mechanism to provide a large-current path to electrical apparatuses on the steering wheel. The slip ring mechanism includes annular stationary contacts, annular movable contacts, and floating contacts. The annular stationary contacts are provided on the stationary housing and oppose the floating spacers to extend along a path of pivotal movement thereof. The annular movable contacts are provided on the rotative housing and oppose the floating spacers to extend along the path of pivotal movement thereof. The movable contacts are connected to electrical apparatuses on the steering wheel side. The floating contacts are provided on the floating spacers and are in resilient contact with the stationary contacts and the movable contacts.
