The invention discloses a spherical brush type electric sliding ring, comprising a rotor insulating cover plate and a stator insulating base, at least two rotor conductive rings, at least two stator conductive rings, at least two rotor electrodes, at least two stator electrodes and at least two groups of spherical brushes. The rotor insulating cover plate is rotatably assembled on the stator insulating base; the rotor conductive rings and the rotor conductive rings are respectively and concentrically assembled between the rotor insulating cover plate and the stator insulating base; at least one group of the spherical brushes is arranged in a rolling fit manner between each rotor conductive ring and the rotor conductive ring matched with the rotor conductive ring; the rotor electrodes are respectively connected with the corresponding rotor conductive rings through the rotor insulating cover plate; and the stator electrodes are respectively connected with the corresponding stator conductive ring through the stator insulating base. The rotor conductive rings, the spherical brushes and the stator conductive rings are both conductive contact elements and bearing motion elements, so that the spherical brush type electric sliding ring provided by the invention has the characteristics of simple and compact structure, very small volume, high rotating speed, low abrasion, strong current passing capacity and the like.
