Plastic casing used for commutator compression molding

The utility model discloses a plastic casing used for commutator compression molding. The plastic casing used for commutator compression molding is characterized in that the plastic casing is provided with a cylindrical casing body; commutator copper bar slots are uniformly distributed and arranged on the inner circumferential surface of the cylindrical casing body; the height of a copper bar slot starts from the upper end face of the cylindrical casing body and stops at the lower end face close to the cylindrical casing body. The middle part of adjacent copper bar slots is provided with ribs which are uniformly distributed on the inner circumferential surface of the cylindrical casing body. According to the utility model, the plastic casing used for commutator compression molding can be used to produce an all-plastic commutator without milling an insulating slot, thus the production efficiency is improved, and the labor cost is reduced.
