The wiring sleeve 2 is used for accommodating and insulating a winding lead wire and a power line terminal in the stator assembly, and the wiring sleeve 2 is externally arranged on the outer side of the frame main body 1.

For technical scheme among the correlation technique, arrange the wire sleeve outside the insulating frame in this application outside, like this, can not set up in the notch because of the wire sleeve, to winding wire-wound influence, avoided the wire sleeve to damage the enameled wire of winding.

In addition, because the wire sleeve 2 in this application is arranged outside the insulating frame 10, after the winding on the insulating frame 10 is completed, when the notch 11 of the insulating frame 10 needs to be injection-molded, no wire sleeve occupies the space of the notch 11 in the notch 11, and therefore, enough space is available in the notch 11 for injection molding. In order to clearly illustrate the differences between the present application and the related art, the applicant makes the following corresponding descriptions:

in the technical scheme in the related art, as the wiring sleeve is arranged in the notch, when the notch needs to be subjected to injection molding, the distance between the wiring sleeve and the edge of the notch is smaller for the notch provided with the wiring sleeve, and the injection molding material can only be arranged in a smaller space between the wiring sleeve and the opening of the notch, so that the problems of uneven adhesion of the injection molding material, poor injection molding, leakage groove after injection molding and the like are caused;

the utility model discloses in, the insulating frame outside is located to the wire sleeve 2, and wire sleeve 2 can not occupy the space of notch 11, when moulding plastics notch 11, and the degree of depth in each notch 11 is all bigger, and the material of moulding plastics can be attached to in notch 11 well to can improve the effect of moulding plastics, and overcome some technical problem that may exist among the correlation technique.
