1) the coil is wound by a circle of coils on the winding teeth, so that the reserved wire at the initial end of the upper framework coil is gradually extruded by the later copper wire, the paint skin is scratched, the turn-to-turn defect is caused, and the coil is conducted and burnt.

2) The reserved lines of the upper framework need to be bound and fixed in the insulating framework when collected, and are generally bound by an insulating binding band at present, so that the space is occupied.

3) The insulating groove paper is small in thickness and small in exposed size, and the insulating groove paper is easy to fall off in clamping cooperation with the upper insulating framework and the lower insulating framework, so that the normal operation of the motor is very influenced.

Disclosure of Invention

In order to solve the problem, the utility model provides an insulating skeleton and motor stator can avoid reserving the line and receive extrusion scraping influence intensity to don't just can realize reserving the line collection with any bandage and tighten, insulating skeleton has good cooperation with groove paper. The utility model adopts the technical scheme as follows:

the utility model provides an insulating skeleton, includes the frame circle and is the annular N winding tooth of arranging on the frame circle, winding tooth end is equipped with the dog, be equipped with N on the frame circle inner wall and to being used for the initial wire casing of reserving the line and dodging of coil, it is every right the wire casing corresponds to be established every the both sides position department of winding tooth, N is not less than 2 natural number.

Above-mentioned insulating skeleton, the outer wall top of frame circle is equipped with N and is used for reserving the fixed fixture block of line winding, and every pair fixture block one-to-one sets up in the both sides position department of wire winding tooth.

In the insulating framework, each pair of the clamping blocks is a rectangle with rounded corners, and the two clamping blocks of each pair of the clamping blocks are arranged in a splayed shape.

In the insulating framework, the bottom of each stop block is provided with a pair of positioning grooves for clamping and placing groove paper.

The utility model also relates to a motor stator, which comprises an upper framework, an iron core and a lower framework, wherein the upper framework is the insulating framework; and the bottom of each stop block on the lower framework is also provided with a pair of positioning grooves for clamping and placing groove paper.

Above-mentioned motor stator, the lower skeleton includes the lower frame circle, the bottom of iron core is connected to the bottom of lower frame circle, the top of lower frame circle is equipped with the fool-proof groove of the location assembly position of being convenient for.

The utility model has the advantages that: the initial reserved line of coil can be held to the wire casing, can not extrude this initial reserved line along with the winding of coil, and the enamel skin can not extruded the scratch.

After the coil winding is finished, the reserved line is collected after bypassing the fixture block, the fixture block plays a fixing role for the reserved line, the fixed reserved line can be bound to the other corresponding collecting lines after being close to the collecting lines, the use of an additional binding band is avoided, and the process is attractive.

The end of the slot paper can be clamped in the positioning grooves on the stop blocks in one-to-one correspondence, so that the positioning stability of the slot paper is improved.
