Problems solved by technology

In use, the rotor of the optical rotary connector and the rotor of the electrical rotary connector rotate together to realize the simultaneous transmission of optical and electrical signals in the rotating working mode. The problem with the existing photoelectric composite rotary connector is that it needs to be connected by screws Ensure the coaxiality of the stator of the electric rotary connector and the stator of the optical rotary connector, and then ensure the coaxiality of the rotor of the electrical rotary connector and the rotor of the optical rotary connector. Accumulated errors, the optical rotary connector and the electric rotary connector are prone to misalignment, which may easily cause the rotation delay of the rotary connector, the large change in the insertion loss of the optical rotary connector, and the large change in the contact resistance of the electric rotary connector; in addition The axial dimension overlap between the optical rotary connector and the electrical rotary connector is less, resulting in a larger axial dimension of the optoelectronic composite rotary connector
