The invention provides an assembly structure, a stator assembly, a plastic package motor and an air conditioner. The assembly structure is used for assembling an insulating sheath and a stator framework, and is characterized in that brackets are arranged on the stator framework; support columns are arranged on the insulating sheath; two adjacent brackets forms an assembly groove in an enclosed manner, and the support columns are respectively installed in the assembly grooves; each assembly groove is internally provided with a limit structure, and the limit structure is used for keeping the support column in the assembly groove so as to prevent the support column from moving in the assembly groove. According to the invention, the limit structure fixes and keeps the support column in the groove, and the support column cannot move in the axial direction, thereby ensuring that the insulating sheath can protect contact pins. The assembly structure can complete the accurate positioning for the insulating sheath and the stator framework only through the support columns and the brackets, does not need the additional arrangement of positioning columns or positioning holes, simplifies the structure of the insulating sheath and the stator framework and saves the material cost. The support columns and the brackets are large in size, thereby being easy to distinguish, being capable of reducing the positioning difficulty, and improving the assembly efficiency.
Description
technical field [0001] The invention belongs to the technical field of plastic-sealed motors, and in particular relates to an assembly structure, a stator assembly, a plastic-sealed motor and an air conditioner. Background technique [0002] The insulating sheath is an injection molded part used in plastic-encapsulated motors, which plays the role of fixing lugs or pins, protecting solder joints and positioning of wiring boards. According to different usage conditions, the insulating sheath is divided into two types: full-circle motor insulating sheath and chain insulating sliding sleeve. [0003] The chain-type insulating sheath has two parts with a symmetrical structure. When installing, the pins on the skeleton pass through the corresponding through holes on the chain-type insulating sheath, and need to pass through the positioning columns of the insulating sheath and the positioning on the stator frame. The hole fits for positioning. After installation, there is no stab...
