The utility model discloses preparation simple process, light in weight, with low costs, sound construction, heat dispersion are good, can better satisfy direct current motor's high rotational speed operational requirement.
Description
Technical field
The utility model is related to a kind of improvement invention of Hooked reverser.
Background technology
The Hooked reverser of prior art, including plastic substrate and the commutation copper of the uniform screening of excircle in plastic substrate
Piece, the medial surface of commutation copper sheet will set hook to be implanted into plastic substrate and be combined with plastic substrate, and hook needs cold punching technology
Formed, therefore not only manufacture craft is complex for commutation copper sheet, and also weight weight, the consumptive material of commutation copper sheet are big, cost is high；And
Plastic substrate will be combined with hook, so plastic substrate will be configured with the full-height of commutation copper sheet, therefore plastic substrate
Same weight weight, consumptive material are big, cost is high, while also reducing the heat dispersion of commutator；Further, since the weight of commutation copper sheet
Weight rotary inertia is big, and to improve the sound construction degree of commutator, the medial surface of commutation copper sheet often there is provision of in above-below direction
Strengthen annular groove and place reinforcing ring, therefore commutator structure is increasingly complex also increases cost；Further, the crotch of commutation copper sheet is in weldering
The often row's of generation phenomenon during line, causes bonding wire poor quality, influences electrical machinery life.In a word, the hook commutation of prior art
Device, because weight weight, heat dispersion are poor, above-mentioned factor all directly affects the high rotary speed working requirement of direct current generator.
The content of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of manufacture craft is simple, lightweight, cost
Low, sound construction, perfect heat-dissipating, can more preferably meet the Hooked reverser of the high rotary speed working requirement of direct current generator.
The utility model adopts the following technical scheme that to complete：
Hooked reverser, it is characterised in that：Commutation copper sheet including surrounding cylinder, the interior lateral surface of commutation copper sheet is
Clearance for insulation is left between smooth, cylindrical peripheral surface, adjacent commutation copper sheet, the top of commutation copper sheet carries crotch, the top of commutation copper sheet
It is connected with upper lid, upper lid is more than the external diameter of cylinder to form commutation copper with the integral injection-compression molding of commutation copper sheet, the external diameter of upper lid
The upper reinforcing ring of piece, the bottom of commutation copper sheet is connected with lower cover, and the external diameter of lower cover is more than the external diameter of cylinder to form commutation copper
The lower reinforcing ring of piece.
After adopting the above technical scheme, the structure of Hooked reverser is greatly optimized, the medial surface of 1. commutation copper sheets is not
Hook need to be set, and manufacture craft is simple, lightweight, cost is low, and the rotary inertia of commutation copper sheet is small；2. modeling is replaced by upper and lower covers
Expect matrix, need to only consider to reserve the distance that commutation copper sheet contacts with carbon brush between upper and lower covers and be combined without consideration with hook, because
This upper and lower covers is not required to be configured with the full-height of commutation copper sheet, and upper and lower covers are compared to plastic substrate is lightweight, consumptive material is few, cost
It is low, while making the center section of commutation copper sheet be completely formed hollow out design, improve the heat dispersion of commutator；3. upper and lower covers
External diameter be more than the external diameter of cylinder, i.e. upper and lower covers can also directly be formed from the lateral direction banding commutation copper sheet of commutation copper sheet
The reinforcing ring up and down of commutation copper sheet, improves the sound construction degree of commutator；4. commutator is lightweight, sound construction, heat dispersion
It is good, while the rotary inertia of commutation copper sheet is small, therefore, it is possible to more preferably meet the high rotary speed working requirement of direct current generator.
Preferably, being abutted on the inside of the outer circular top part and crotch of the upper lid.By above-mentioned design, in bonding wire
Upper lid can give crotch support on the inside of crotch, it is to avoid crotch produces the row's of falling phenomenon, it is ensured that bonding wire quality, and then ensures the motor longevity
Life.
Preferably, the adjacent side of the commutation copper sheet is recessed provided with arc.By above-mentioned design, one is that can mitigate to change
To the weight of copper sheet, while will not make the manufacture craft of commutation copper sheet becomes complicated（Because commutation copper sheet is with copper wires mostly
Formed using drawing process）；Two be that can increase the bond strength between commutation copper sheet and upper and lower covers.

The utility model has drawings described below：
Fig. 1 is the shape assumption diagram of Hooked reverser,
Fig. 2 is Fig. 1 top-direction view,
Fig. 3 is Fig. 2 A-A views,
Fig. 4 is Fig. 3 B-B views.
Embodiment
As illustrated, Hooked reverser of the present utility model, including 22 commutation copper sheets 3 of cylinder are surrounded, change
It is smooth, cylindrical peripheral surface to the interior lateral surface of copper sheet 3, clearance for insulation 6, the phase of commutation copper sheet 3 is left between adjacent commutation copper sheet 3
Adjacent side is provided with arc recessed 5, and the top of commutation copper sheet 3 carries crotch 4, and the top of commutation copper sheet 3 is connected with upper lid 1, upper lid 1
Using bakelite powder material, upper lid 1 is more than the external diameter of cylinder to be formed with the integral injection-compression molding of commutation copper sheet 3, the external diameter of upper lid 1
The upper reinforcing ring of commutation copper sheet 3, the bottom of commutation copper sheet 3 is connected with lower cover 2, and lower cover 2 uses bakelite powder material, and lower cover 2 is with changing
To the integral injection-compression molding of copper sheet 3, external diameter of the external diameter more than cylinder of lower cover 2 is described to form the lower reinforcing ring of commutation copper sheet 3
