Abstract
A splicing insulation lining relates to an insulation lining of a motor. In the prior art, splicing parts of an upper insulation lining are arranged inside or outside splicing parts of a lower insulation lining, a copper line will be wound on the splicing parts of the upper and lower insulation linings whether the copper line is wound clockwise or anticlockwise, thus the copper is damaged, and the turn-to-turn short circuit is caused; more seriously, the copper wire is contacted directly with an iron core, and the overpressure resistant performance becomes bad. The upper insulation lining is composed of a first splicing part and a second splicing part, the lower insulation lining is composed of a third splicing part matched with the first splicing part, and a forth splicing part matched with the second splicing part, and the second and third splicing parts are respectively arranged outside the first and forth splicing parts. In the splicing insulation lining, the traditional lining splicing method is changed, the problems of stator turn-to-turn short circuit and bad overpressure resistant performance caused by shortages of the design of the insulation lining are effectively avoided, internal ill manufacturing is reduced, and the safety service life of the motor is prolonged.

As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature.
The last oblique splicing limit face gradient of described first, second stitching section is identical, and the following oblique splicing limit face gradient of described the 3rd, the 4th stitching section is identical and complementary with last oblique splicing limit face gradient.Can keep the straight of insulating bushing lateral surface after said structure makes first, second stitching section and third and fourth stitching section cooperates and guarantee to have enough intensity.
Described oblique splicing limit face and intersection, last insulating bushing lower surface are the arc transition face, and following oblique splicing limit face is the arc transition face with intersection, following insulating bushing upper surface.The arc transition face can play guiding, is convenient to both grafting assemblings.
Described first, second, third and the root of the 4th stitching section be provided with the horizontal confined planes that matches with corresponding stitching section end face.Confined planes and stitching section end face match, and guarantee the size of the short transverse of insulating bushing.
Described first stitching section is positioned at the left side of insulating bushing, and described second stitching section is positioned at the right side of insulating bushing.When the clockwise coiling of copper cash, prevent copper cash collision insulating bushing jointing positions up and down, the interturn in stator windings short circuit that the copper cash of damaging causes, withstand voltage bad.
Described first stitching section is positioned at the right side of insulating bushing, and described second stitching section is positioned at the left side of insulating bushing.When the counterclockwise coiling of copper cash, prevent copper cash collision insulating bushing jointing positions up and down, the interturn in stator windings short circuit that the copper cash of damaging causes, withstand voltage bad.
Beneficial effect: change the conventional bushings joining method, prevent that effectively minimizing inside is made bad, improves the safe operating life of motor because of not enough interturn in stator windings short circuit, the withstand voltage bad problem of causing of insulating bushing design.
