CN204809612U - Assembly type commutator copper sheet - Google Patents

Abstract

The utility model discloses an assembly type commutator copper sheet colludes the foot by lamellar body and upper and lower two and constitutes, its characterized in that: inlays the dress hole about the side direction of lamellar body is equipped with, colludes foot area insertion, the shape of insertion and the shape phase -match that inlays the dress hole, the insertion that colludes the foot pack into inlaying of lamellar body adorn downthehole, the insertion with inlay dress hole interference fit, the insertion expand tightly inlaying adorn downthehole. The utility model discloses simple structure can collude the foot according to the independent nimble design of the different strength requirements of commutator, then combine with the lamellar body, not only better satisfies the commutator strength requirement, moreover the lamellar body, collude the foot and can realize general design, reduce the mould and be equipped with, collude the material that the foot optional is different from the lamellar body simultaneously, practice thrift the cost.

Description

Packaging copper segment

[technical field]

The utility model relates to a kind of commutator, is specifically related to a kind of copper segment.

[background technology]

Commutator is applied on rotor, and the major part of commutator is exactly copper segment.The copper segment of prior art, be made up of body portion and hook part, lamellar body and hook are structure as a whole, for the commutator of dissimilar, different size, varying strength, the structure of its copper segment is all different, comprises the difference of lamellar body and the difference of hook, hook determines the bond strength of copper segment and commutator matrix, be equivalent to the mechanical strength determining commutator product, because lamellar body and hook are all different, so the punching die of copper segment will be equipped with a lot; Also have, because be disjunctor with lamellar body, so the design meeting critical constraints of hook, for ensureing the bond strength between copper segment and commutator matrix, it is comparatively large that hook often will design, and hook can only be same copper material with lamellar body, the material in addition on hook limit all want when hook is shaping punched fall, will cause larger spillage of material like this, cost is high.

[summary of the invention]

In view of the deficiencies in the prior art, it is simple that the purpose of this utility model aims to provide a kind of structure, independent flexible design hook can be required according to commutator varying strength, then be combined with lamellar body, not only better meet commutator requirement of strength, and lamellar body, hook can realize universal design, reduce mould and be equipped with, hook can select the material being different from lamellar body, cost-saving packaging copper segment simultaneously.

The utility model takes following technical scheme:

Packaging copper segment, be made up of lamellar body and upper and lower two hooks, it is characterized in that: the side surface direction of lamellar body is provided with upper and lower inlaid hole, hook band insertion, the shape of insertion and the mating shapes of inlaid hole, the insertion of hook loads in the inlaid hole of lamellar body, and insertion and inlaid hole interference fit, insertion swelling is in inlaid hole.

Hook has swallowtail shape.

Lamellar body adopts copper material, and hook adopts high-strength nylon material or ferrous material.

After adopting technique scheme, copper segment is made up of the lamellar body of Split type structure and hook, lamellar body, then hook is independently shaping separately fits together, structure is simple, hook can require and independent flexible design according to commutator varying strength, shaping to be designed to according to carrying out independence again, therefore, it is possible to better meet commutator requirement of strength, and lamellar body, hook can realize universal design, as long as combine, reduce mould to be equipped with, hook can select the material being different from lamellar body simultaneously, it is less that hook size also can design, do not need yet the material on hook limit when hook is shaping punched fall, cost-saving.

[accompanying drawing explanation]

The utility model has the following drawings:

Fig. 1 is the structural representation of utility model,

Fig. 2 is the Split type structure figure of Fig. 1,

Fig. 3 be Fig. 1 overlook directional diagram.

[embodiment]

As shown in the figure, packaging copper segment of the present utility model, be made up of lamellar body 1 and upper and lower two hooks 4, the side surface direction of lamellar body 1 is provided with upper and lower inlaid hole 2, hook 4 is with insertion 3, the shape of insertion 3 and the mating shapes of inlaid hole 2, the insertion 3 of hook 4 loads in the inlaid hole 2 of lamellar body 1, insertion 3 and inlaid hole 2 interference fit, insertion 3 swelling is in inlaid hole 2, hook 4 has swallowtail shape, and lamellar body 1 adopts copper material, and hook 4 adopts high-strength nylon material or ferrous material.
