Background technology

Diverter is one of critical piece of brush motor, is widely used in electric motor, and which is according to manufacturer Method is broadly divided into insert piece type reverser and rolling diverter.Insert piece type reverser is typically using the single commutator segment copper of the row's of drawing punching Piece, then through screening operation, most after Jing injection steps make.Rolling diverter is typically adopted by after the punching of copper sheet material, bending Copper shell is formed, by it and insulating body injection mo(u)lding after cleaning, then turning, groove milling forms single commutator segment, eventually pass Crotch is made.Wherein, rolling diverter reduces the operation of artificial inserted sheet to a certain extent relative to insert piece type reverser, therefore Production efficiency is improve, cost of labor is reduced.

As shown in figure 1, the upper and lower ends of the inwall axial location of traditional diverter housing 1 ' are provided with opposite bending Hook 2 ', so as to insulating body 3 ' is firm be molded in diverter housing 1 ', and then simple structure, easy-formation.But, due to In production process, diverter housing adopts metal material of copper, insulating body 3 ' typically to adopt bakelite, bakelite and diverter housing 1 ' Inwall be nature laminating, conjugation is low between the two, and it is different from the shrinkage factor of copper product to add bakelite, after heat treatment, Diverter housing 1 ' is larger compared to bakelite deformation, and then again by diverter and motor erection welding, diverter housing 1 ' is radially Deflection is further change in, in turn result in diverter housing 1 ' circularity and molding after commutator segment between Change of gravity difference of surveying segments increase Greatly, the final overall performance for affecting electric motor.Therefore, the conjugation between bakelite and diverter housing how is improved, to subtract After fractional motor erection welding, the deflection of diverter housing becomes nowadays problem demanding prompt solution.

Utility model content

For this purpose, the technical problems to be solved in the utility model is to overcome diverter housing and the injection mo(u)lding of prior art Bakelite conjugation it is low, in turn result in diverter housing circularity and molding after commutator segment between Change of gravity difference of surveying segments increase Technological deficiency, so as to provide a kind of and high diverter housing of bakelite conjugation.

To achieve these goals, this utility model provides a kind of diverter housing, including the cylinder with central axis hole Body, it is circumferentially distributed in inner body wall to have some axially extending grooves, in inner body wall be located at adjacent grooves between Axial positions form least one set coupler body.

Preferably, the end of the two side of groove stretches to form hook towards bottom land angle folding respectively, on two side Hook radially relatively close extension.

Preferably, groove is the dovetail groove or T-slot that width radially increases.

Preferably, each group of coupler body includes upper hook body and the axial corresponding lower hook body below upper hook body therewith, Upper hook body is extend inwardly downward hook-shaped, and lower hook body is inwardly upwardly extending hook-shaped.

Preferably, each group of coupler body includes upper hook body and the axial corresponding lower hook body below upper hook body therewith, Upper hook body is inwardly upwardly extending hook-shaped, and lower hook body is extend inwardly downward hook-shaped.

Preferably, every group of coupler body projects molding towards the radial direction of cylindrical body, every group of coupler body has a ditch Groove, groove have two relative side walls, radial direction inwardly open extension of the side wall towards cylindrical body.

Preferably, the upper surface of body is circumferentially arranged some equally distributed Piece Claws, Piece Claw is in outward bending Hook solid, and be correspondingly arranged between adjacent grooves.

To achieve these goals, this utility model also provides a kind of diverter, including the diverter shell with central axis hole Body, and it is arranged on the insulating body of diverter enclosure interior, it is characterised in that diverter housing is described in any of the above item Diverter housing.

As described above, this utility model diverter housing makes diverter shell by way of being combined with coupler body using groove Conjugation between body and the insulating body of injection mo(u)lding is significantly improved, meanwhile, reduce the footpath of body by opening up groove To diameter, effectively reduce the deflection caused by electric motor erection welding, so as to ensure that the circularity of diverter housing with And the segment difference between the commutator segment after molding.
