Abstract
The utility model relates to a ring collector, comprising a cylinder body and conductors positioned on the cylinder body and are divided with each other. The utility model is characterized in that the inner surfaces of the conductors are provided with barbs which are penetrated in the cylinder body for causing the conductors to be fastened on the surface of the cylinder body. The utility model has the advantages of no looseness and shift of copper sheets, no short circuit phenomenon, high precision and small size, when the utility model is assembled on a motor, the utility model has the advantages of little resistance under high speed running, small jump of electric brushes and small wear on surfaces.
Description
A kind of commutator, relate to generator and or motor in rectifying device.
The small-sized commutator that uses generally is by insulated ring some copper sheets to be enclosed within the plastics garden on the whole at present.Copper sheet easily was shifted after this commutator was fitted into motor, was short-circuited thereby hit phase matter copper sheet; Bigger rectification then is embedded on the plastic body by the dovetail on the copper body, and it is numerous and diverse that this commutator has manufacturing, the deficiency that materials are many.
The purpose of utility model provides a kind of commutator, and it has firmly, the characteristics that precision is high.
Adopt such technical scheme according to the above-mentioned purpose utility model: this commutator includes Cylinder and the conductor that is positioned on the Cylinder, be spaced from each other between conductor, the inner surface that is characterized in conductor has hangnail, and described hangnail thrusts and makes conductor be anchored on the Cylinder surface in the Cylinder.
Because conductor is anchored on the Cylinder surface, so copper sheet can loose shift, can not produce short circuit phenomenon, and quality precision height, volume are little, when commutator be contained in fit on the motor after, that in running up, resistance is little, brush is beated is little, surface abrasion is little.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
The commutator structural representation that Fig. 1 the utility model proposes for foundation.
Fig. 2 is the A-A cut-away view of Fig. 1.
Another example structure schematic diagram of commutator that Fig. 3 the utility model proposes for foundation.
Fig. 4 is the B-B cut-away view of Fig. 3.
Commutator the 3rd example structure schematic diagram that Fig. 5 the utility model proposes for foundation.
Fig. 6 is the C-C cut-away view of Fig. 5.
Below in conjunction with drawings and Examples the commutator that foundation the utility model proposes is further described.
As shown in Figure 1, comprise Cylinder (3) and be anchored on conductor (1) composition on Cylinder surface that Cylinder is generally working of plastics according to the commutator that the utility model proposes, guiding element is generally copper sheet.In conductor and the contacted one side of Cylinder, promptly the inner surface of conductor is processed with hangnail (2), and hangnail thrusts in the Cylinder.Add and at first copper sheet is processed into mutual shape man-hour, process hangnail at the mutual inner surface of shape copper sheet.For example, can be at smooth copper sheet inner surface, backing-off cutting goes out some hangnails.Perhaps with the copper strips of certain thickness and width by rolling the thorn head, thereby its surface is produced certain requirement height and rare close thorn post that is evenly distributed are arranged, use then instead towards the angled circular arc sheet of once-forming, then copper sheet is installed in the mould, process cast solid with plastic hot.End (5) at Cylinder preferably processes tapering, and the copper sheet that is positioned at the end is pressed on the conical surface.And the end of copper sheet (4) preferably are hook solid, so that fixing cord.Referring to Fig. 2, generally be fixed with the conductor (1) more than three and three on Cylinder (3) again, every conductor inner surface all has hangnail (2), and separates not conducting mutually mutually between every conductor.Have better insulating properties between the conductor for making, the conductor side is preferably parallel to each other.
Among Fig. 3, Fig. 4, identical among conductor and cylindrical draw bail and Fig. 1 and Fig. 2.But be processed with breach (6) in the end of every conductor, so as when to install lead embed wherein and welding fixing.
Conductor is also identical with Fig. 1 and Fig. 2 with cylindrical draw bail among Fig. 5, Fig. 6.But end conductor is to radially being bent to form connector lug (7), so that lead is around connector lug when installing.
Claims (6)
1, a kind of commutator includes Cylinder and is positioned at conductor spaced apart from each other on the Cylinder, it is characterized in that the inner surface of conductor has hangnail, and described hangnail thrusts in the Cylinder, and conductor is anchored in the Cylinder, makes conductor be anchored on the Cylinder surface.
2, commutator according to claim 1 is characterized in that the end of Cylinder has tapering, and end conductor is pressed on the conical surface.
3, as commutator as described in the claim 2, it is characterized in that the end of conductor all is hook solid.
4, commutator according to claim 1 is characterized in that the conductor side is parallel to each other.
5, commutator according to claim 1 is characterized in that the end of conductor is processed with breach.
6, commutator according to claim 1 is characterized in that end conductor is to radially being bent to form connector lug.
