The connecting portion of the insulation protection frame of prior art is the swash plate 15 that has on the outstanding insulation protection frame outer peripheral face of two semicircle insulation protection frame faying faces separately towards own semicircle direction inclination,
There is following shortcoming in the prior art:
The connecting portion that connects two semicircle insulation protection framves in the prior art is the swash plate that has on the outstanding insulation protection frame outer peripheral face of two halves round insulation fender bracket faying face separately towards own semicircle direction inclination.There is a fixed gap between the swash plate of this structure; copper cash takes place in the coiling process of producing easily around in the space between the iron core outer insulation fender bracket swash plate; copper cash is cut and damaged, cause copper cash to contact, cause stator broken string or short circuit with stator core.Therefore need do over again rebuilding or cause producing waste product causes waste, has reduced production efficiency, even has influenced whole plastic packaging motor and household air-conditioner.
Summary of the invention
The present invention provides a kind of copper cash not to be insulated fender bracket to cut and damage the stator insulation protection holder of the single-phase asynchronous plastic packaging motor that two halves round insulation fender bracket binding site is combined closely for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The stator insulation protection holder of single-phase asynchronous plastic packaging motor of the present invention, plastic packaging motor comprises: be fixed on the stator on the frame; Be positioned at stator interior, by rotor rotated on the rotating shaft of bearing supporting; The end cap of rotating shaft terminal and vibration absorber; And the insulating material of parcel stator and rotor periphery; The circular stator core that stator is connected to form by dovetail groove by two semicircle stator cores; The stator core inboard is provided with a plurality of protuberances with radial protrusion, and the copper cash line bag on the stator core outer ring is arranged in the wire casing between two protuberances; On the stator core two sides, respectively there are a shape and stator core shape akin between stator core and the copper cash line bag, two semicircular insulation protections that connected by connecting portion are configured to; The insulation protection frame has the circular circumference face, and there is radial protrusion the inboard, and a plurality of insulation protection frame protuberances corresponding with stator core form dovetail groove between two insulation protection frame protuberances; The connecting portion of two semicircle insulation protection frame is to have the concaveconvex structure that matches on the outstanding insulation protection frame cylindrical of the symmetrical two ends setting of two semicircle insulation protection frame faying faces.
Described concaveconvex structure is on a semicircle insulation protection frame dome to be arranged, and corresponding circular groove is arranged on another semicircle insulation protection frame.
Dome on described two semicircle insulation protection framves is an interference fit with cooperating of circular groove.
The degree of depth of described circular groove is greater than the radius of circular groove.
Advantage and good effect that the present invention has are:
The stator insulation protection holder of single-phase asynchronous plastic packaging motor of the present invention is because the concaveconvex structure that the connecting portion of two semicircle insulation protection framves has interference fit makes two halves round insulation fender bracket binding site combine closely tight.Avoided copper cash around to iron core and the phenomenon of stator broken string or short circuit takes place.Reduce do over again rebuilding rate and percent defective, improved production efficiency.
In addition, two semicircle insulation protection framves adopt the concaveconvex structure of interference fit, make stator core combine closely, thereby have improved the deviation in roundness of diameter of stator bore.
