Description

Combined commutator Technical Field The utility model relates to the technical field of motors, in particular to a combined commutator. Background Commutators are key components in both dc and ac commutator machines, and are typically composed of a plurality of segments, typically copper, arranged in a ring and insulated from each other. The commutating pieces are separated by mica sheets and other insulating materials to prevent short circuit; the commutator segment and the base of the existing commutator are often glued, and are damaged locally, so that the whole commutator cannot be used, and resource waste is easily caused. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a combined commutator. (II) technical scheme In order to achieve the purpose, the utility model provides the following technical scheme that the combined commutator comprises a base and copper sheets, wherein a plurality of groups of copper sheets are arranged on the periphery of the base, a bent pin is arranged at the center of one end of each copper sheet, and the combined commutator further comprises: The connecting piece comprises a supporting ring, guide frames and a connecting seat, wherein the supporting ring is arranged on the outer wall of one end, far away from the bent leg, of the base, a plurality of groups of guide frames are arranged above the supporting ring, the guide frames are in a T shape, the upper side and the lower side of the guide frames are communicated, through holes matched with the guide frames are formed in the supporting ring, the connecting seat connected with the guide frames is arranged on the back side of the copper sheet, and T-shaped grooves matched with the guide frames are formed in the connecting seat; The base is also provided with fixing pieces for fixing a plurality of groups of copper sheets.
