Abstract

The invention discloses an insulation protective sleeve for a motor stator. Mold opening and ejecting are conducted according to the part, making contact with a stator body, of the insulation protective sleeve to form the insulation protective sleeve. The insulation protective sleeve comprises an end face cover, stator shaft sleeves and empty grooves. The free tail end of each stator shaft sleeve is provided with a butt joint protruding head in a protruding module, wherein the butt joint protruding heads are matched with a butt joint insulation protective sleeve body. A guide corner is arranged at one end of each butt joint protruding head. The side face of each butt joint protruding head is provided with a buckle groove in a concave mode, wherein the buckle grooves are buckled with the butt joint insulation protective sleeve body. The buckle grooves are evenly formed in the annular direction. Thus, butt joint reliability is greatly improved, gaps can be prevented from existing in the butt joint, short circuit of windings is avoided, and quality of a motor is improved.

Description

A kind of insulation protective jacket of motor stator
Technical field
The present invention relates to motor device field, be specifically related to a kind of insulation protective jacket of motor stator.
Background technology
Coil of stator of motor is in the past in the time entering iron core, method is that insulating paper is cut into small pieces for separating stator and copper cash, then by copper cash around entering, in this process, because being is manually encased inside well iron core by blocks of insulating paper record book in accordion form, like this can cannot ensure the every complete flanging of the scraps of paper get well and be encased inside iron core, and record book in accordion form insulating paper be encased inside after as meet knuckle etc. and be difficult for being found, also there will be the scraps of paper easily loosening, therefore, in order to deal with problems, people afterwards utility model a kind of insulation protective jacket of motor stator, refer to No. 201010539722.6 patent application of Chinese Patent Application No., it has disclosed a kind of insulation protective jacket of motor stator, comprise stator axle sleeve, end face cover and dead slot, when use, that two insulation protective jackets are enclosed within motor stator from both sides respectively, thereby the surface of motor stator and internal diameter are all wrapped, there is following defect in the insulation protective jacket of this kind of structure: in the time that two insulation protective jackets connect, owing to not being provided with bayonet unit between two insulation protective jackets, therefore both are easier to get loose, once get loose will there is space in joint, copper cash just may contact stator core, cause coil and iron core short circuit.
Therefore, be necessary to provide a kind of insulation protective jacket of the motor stator solving the problems of the technologies described above.
Summary of the invention
Technical problem to be solved by this invention is: the insulation protective jacket that a kind of motor stator that improves docking reliability is provided.
For solving the problems of the technologies described above; the technical solution used in the present invention is: a kind of insulation protective jacket of motor stator; described insulation protective jacket is to penetrate and form according to the part die sinking contacting with stator body; described insulation protective jacket comprises end face cover, stator axle sleeve and dead slot; the free terminal of described stator axle sleeve convexes with and the docking plush copper of docking insulation protective jacket and matching; the end of described docking plush copper is provided with lead angle; the side of described docking plush copper is concaved with and the buckle groove that docks insulation protective jacket phase buckle, and described buckle groove is hoop and evenly arranges.
As the preferred technical scheme of one, described insulation protective jacket is made up of insulating material, and wall thickness is 0.2-1.2mm.
As the preferred technical scheme of one, described insulating material is PA or PPS or nylon.
As the preferred technical scheme of one, the flute profile of described dead slot is identical with the flute profile of stator core.
The invention has the beneficial effects as follows: the present invention convexes with and the docking plush copper of docking insulation protective jacket and matching by the free terminal of described stator axle sleeve; the side of described docking plush copper is concaved with and the buckle groove that docks insulation protective jacket phase buckle; thereby make two insulation protective jacket docking more reliable; prevent that joint from existing gap; and then can avoid short circuit in winding, lifting motor quality.
