Description

Stator and winding framework mounting structure

Technical Field

The utility model relates to a stator and bobbin mounting structure of motor.

Background

The winding frame of the motor is a part of a winding coil winding, the winding frame needs to be assembled with a stator hole of a stator, the winding frame is provided with winding posts, a coil is wound on the winding posts, a winding groove is formed between the two winding posts and used for accommodating winding, the groove bottom of the traditional winding groove is an arc shape with reference to the hole wall of the stator hole, and therefore the thickness of the edge of the frame is smaller, and the thickness of the frame is shown in fig. 4. In the winding process, no practical space is left at the bottom of the framework, and the winding cannot be wound to the bottom of the winding groove. Therefore, the strength of the framework in the existing design is not enough, and the winding post of the winding framework is easy to deform during winding.

Disclosure of Invention

An object of the utility model is to provide an improve wrapping post root and skeleton edge's thickness to improve wrapping post's structural strength's stator and bobbin mounting structure.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a stator and winding skeleton mounting structure, includes stator and winding skeleton, is equipped with the stator hole on the stator, winding skeleton installs in the stator hole, winding skeleton is equipped with a plurality of wrapping post, is equipped with the wire winding groove between the adjacent wrapping post, the tank bottom in wire winding groove is V type structure, and two V type trough limit perpendicular to adjacent wrapping posts of tank bottom.

Preferably, the outer end of the winding post is provided with a limiting protrusion.

Preferably, the winding framework is provided with a positioning hole.

After the structure is adopted, the utility model discloses because the tank bottom in wire winding groove is V type structure, and two V type trough limits of tank bottom perpendicular to adjacent wrapping post. Therefore, the thickness of the root of the wrapping post and the edge of the framework is increased, the structural strength of the wrapping post is improved, and therefore when wires are wound, the wrapping post cannot deform, and the service life of a product is prolonged.

Drawings

FIG. 1 is a sectional view of the structure of the present invention;

FIG. 2 is an enlarged view of section I of FIG. 1;

FIG. 3 is a schematic view of a bobbin;

fig. 4 is a prior art schematic of fig. 2.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.

Referring to fig. 1, 2 and 3, a stator and bobbin mounting structure, including stator 1 and bobbin 2, is equipped with stator hole 11 on the stator 1, bobbin 2 installs in stator hole 11, bobbin 2 is equipped with a plurality of wrapping post 21, is equipped with wire winding groove 22 between the adjacent wrapping post 21, the tank bottom of wire winding groove 22 is the V type structure, and two V type trough sides perpendicular to adjacent wrapping post 21 of tank bottom.

Referring to fig. 1 and 2, the outer end of the winding post 21 has a stopper protrusion 3. Convenient wire winding and can also have the limiting function.

Referring to fig. 3, a positioning hole 4 is formed on the bobbin 2. The positioning of the winding framework 2 and the stator 1 during assembling is facilitated.

Referring to fig. 4, in the prior art, the slot bottoms of the winding slots 22 are all designed into arc shapes with reference to the hole walls of the stator holes, which results in a thinner skeleton edge, and thus the strength of the winding posts 21 is insufficient, and the winding posts deform during winding. Referring to fig. 1, 2, 3 show, the utility model discloses because the tank bottom at wire winding groove 22 is V type structure, and two V type trough limits of tank bottom perpendicular to adjacent wrapping post 21, consequently increased the root of wrapping post 21 and the thickness at wire reel 2 edges, improved wrapping post 21's structural strength to when wire winding, wrapping post 21 can not warp, improves the life of product.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
