Abstract
The utility model discloses a kind of novel collector ring, comprise two copper rings, lead-in wire and plastic injection pieces.The inwall of two copper rings possesses the laciniation made through sawtooth pattern mould, is used for deepening the connection tightness degree between copper ring and plastic injection piece, prevents copper ring from moving and rotates.The laciniation that the utility model adopts sawtooth pattern mould to make, the mode of jet-bedding than ever, decreases manufacturing procedure, improves production efficiency, reduce cost of goods manufactured, and improve the welding quality between lead-in wire and copper ring mutually.
Description
Technical field
The utility model relates to alternator for vehicle parts, is specifically related to a kind of novel collector ring of anti-rotation.
Background technology
Collector ring is one of the core component for automobile current generator, its composition structure as shown in Figure 1: two copper rings, lead-in wire and plastics.Production technology is first welded on copper ring respectively by lead-in wire, then carry out injection moulding.Because the generator shaft between collector ring turns scooter 3000r/min, move for preventing copper ring and rotate, existing manufacturing process is the several breach of punching press on copper ring, after realizing injection moulding, copper ring fixes, and the shortcoming of this technology is the increase in operation, and (round copper pipe becomes copper ring after cutting, again through punch ram breach, after again copper ring is cut into two copper rings from centre) and cost of goods manufactured, and interfered the welding position of lead-in wire, workman needs contraposition in welding operation, the breach stamped out must be avoided, and its inwall of copper ring of going out of this processes belongs to face, face with wire bonds and welds, welding effect is bad.
Utility model content
The technical problem that the utility model mainly solves is, provides a kind of production technology simple, cheap for manufacturing cost and improves the novel collector ring of welding quality between lead-in wire and copper ring.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel collector ring, comprises two copper rings, lead-in wire and plastic injection pieces, and described copper ring inwall possesses the laciniation made through sawtooth pattern mould.Laciniation has deepened the connection tightness degree between copper ring and plastic injection piece, prevent copper ring from moving and rotate, and the laciniation of copper ring inwall only can be obtained through one-off drawing technique by mould by copper pipe, after the obtained copper pipe possessing laciniation inwall is cut into two required copper rings, decrease manufacturing procedure, improve production efficiency, also reduce the manufacturing cost of product.
As the further improvement of a kind of novel collector ring of the utility model, the even circumference of laciniation is distributed in copper ring inwall, and direction is axially consistent with copper ring.
As the further improvement of a kind of novel collector ring of the utility model, zigzag fashion and size and how many quantity distributed in copper ring determine according to the difference of copper ring diameter.No matter the size of copper ring diameter, all can adopt the copper ring that sawtooth pattern die drawn obtains with laciniation inwall, only directly need customize the sawtooth pattern mould of different-diameter according to the difference of copper pipe diameter.
Another kind as a kind of novel collector ring of the utility model improves, and wire bonds is on copper ring inwall, and copper ring is combined with plastic injection piece after injection moulding, and plastic injection piece contacts with copper ring inwall, is positioned at copper ring.Because the utility model processes laciniation at copper ring inwall, therefore belong to the welding of line face during wire bonds, welding effect is better than original face, face welding, and welding quality is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of general collector ring;
Fig. 2 is the structural representation of copper ring in a kind of novel collector ring of the utility model;
Fig. 3 be after working of plastics injection moulding of the present utility model with copper ring coordinate figure;
Fig. 4 is the cooperation sectional view of copper ring of the present utility model and molded portion.
In figure: 1, copper ring 2, lead-in wire 3, plastic injection piece 4, laciniation.
Embodiment
Clearly understanding to have technical characteristic of the present utility model, object and effect, now contrasting accompanying drawing and describing embodiment of the present utility model in detail.
As shown in Figures 2 to 4, a kind of novel collector ring, comprise two copper rings 1, lead-in wire 2 and plastic injection piece 3, described copper ring 1 inwall possesses the laciniation 4 made through drawing process.Laciniation 4 has deepened the connection tightness degree between copper ring 1 and plastic injection piece 3, prevents copper ring 1 from moving and rotating.Laciniation 4 evenly circumference is distributed in copper ring 1 inwall, and laciniation 4 direction is axially consistent with copper ring 1.No matter the size of copper ring diameter, drawing process all can be adopted to make copper ring with laciniation 4 inwall, only need customize the mould of different size according to the different-diameter of copper pipe.Lead-in wire 2 is welded on copper ring 1 inwall; Described copper ring 1 is combined with plastic injection piece 3 after injection moulding, and plastic injection piece 3 contacts with copper ring 1 inwall, is positioned at copper ring 1.Because the utility model processes laciniation 4 at copper ring 1 inwall, therefore belong to the welding of line face during lead-in wire 2 welding, welding effect is better than original face, face welding, and welding quality is better.
The processing technology of this copper ring is as follows: copper pipe is obtained through a drawing process by cylindrical mold (die curve possessing tooth circumferentially), after the obtained copper pipe possessing laciniation 4 inwall is cut into required copper ring 1.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection range of the present utility model.
Claims (4)
1. a novel collector ring, comprises two copper rings, lead-in wire and plastic injection pieces, it is characterized in that, described copper ring inwall possesses the laciniation made through sawtooth pattern mould.
2. the novel collector ring of one according to claim 1, is characterized in that, the even circumference of described laciniation is distributed in copper ring inwall, and laciniation direction is axially consistent with copper ring.
3. the novel collector ring of one according to claim 1, is characterized in that, zigzag fashion and size and how many quantity distributed in copper ring determine according to the difference of copper ring diameter.
4. the novel collector ring of one according to claim 1, is characterized in that, described wire bonds is on copper ring inwall; Described copper ring is combined with plastic injection piece after injection moulding, and plastic injection piece contacts with copper ring inwall, is positioned at copper ring.
