Abstract
The invention discloses a novel insulation protective jacket. The insulation protective jacket is formed by mold opening and ejection at the portion making contact with a stator body. The insulation protective jacket comprises an end face cover, stator shaft sleeves and empty grooves. Butt-joint concave portions matched with a butt-joint insulation protective jacket are arranged at the free tail ends of the stator shaft sleeves in a concave mode. Lead angles are arranged at the ends of the butt-joint concave portions. The inner side face of the butt-joint concave portion protrudes outwards to be provided with buckling convex portions buckled with the butt-joint insulation protective jacket. The buckling convex portions are annularly and evenly arranged, and therefore the butt-joint reliability is greatly improved, gaps in the butt-joint positions can be avoided, short circuits in windings are avoided, and the motor quality is improved.
Description
Technical field
The present invention relates to motor device field, be specifically related to a kind of novel insulation protective jacket.
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: a kind of novel insulation protective jacket 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 novel insulation protective jacket; 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 is concaved with and the docking recess that docks insulation protective jacket and match; the end of described docking recess is provided with lead angle; the medial surface convex of described docking recess is provided with and the buckle teat that docks insulation protective jacket phase buckle, and described buckle teat 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 is concaved with and the docking recess that docks insulation protective jacket and match by the free terminal of described stator axle sleeve; the medial surface convex of described docking recess is provided with and the buckle teat 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.
