The invention relates to the field of motors, and discloses a plastic
package stator and bearing end cap waterproof sealing structure and a plastic
package motor. The plastic
package stator and bearing end cap waterproof sealing structure comprises a plastic package
stator, a wire retaining clip, a waterproof sealing ring and a bearing end cap, wherein the plastic package stator is provided with an annular clamping
flange with an installation notch, the wire retaining clip is installed in the installation notch, the bearing end cap is provided with an annular clamping groove matched with the annular clamping
flange in a clamped and inserted mode, the annular clamping
flange is provided with an axial end face, the wire retaining clip is provided with a wire clip top
face flush with the axial end face, the annular clamping groove is provided with a bottom groove face, the waterproof sealing ring is elastically compressed between the axial end face and the bottom groove face, and a positioning groove allowing the waterproof sealing ring to be clamped and positioned is formed in the wire clip top face in a concave mode. The plastic package stator and bearing end cap waterproof sealing structure prevents influences of a
needle insertion hole, a detection hole and a detachment notch which probably exist in the radial outer surface of the annular clamping flange on the sealing effect of the waterproof sealing ring, and achieves the aims of improving the waterproof sealing effect between the plastic package stator and the bearing end cap.
