Abstract
The utility model discloses an end face commutator copper sheet, which comprises a sheet body and fixing pins, wherein the upper end face of the sheet body is a working surface; and the lower end face of the sheet body is provided with a groove which is combined with bakelite powder. The end face commutator copper sheet is characterized in that the two side faces of the sheet body are provided with a plurality of small pits. The end face commutator copper sheet disclosed by the invention is reasonable in design, the binding force between the commutator and the bakelite powder can be enhanced during forming of the commutator, and the mechanical strength and overspeed performance of a commutator product are improved.
Description
Technical field:
The utility model relates to a kind of commutator, is specifically related to a kind of copper sheet of end commutator.
Background technology:
The commutator product mainly divides three kinds of hook commutator, tank commutator and end commutators.The mechanical strength of end commutator product and hypervelocity performance and commutator adhesion between copper sheet, the phenolic moulding powder when injection mo(u)lding have great relation, and this just involves the structure problem of copper sheet.Present end commutator copper sheet comprises lamellar body and fixing feet, and the upper surface of lamellar body is a working face, and the lower surface of lamellar body is provided with the groove that combines with phenolic moulding powder, and regardless of the planform of fixing feet, the two sides of lamellar body all are smooth.The deficiency that said structure exists is: copper sheet when the commutator moulding and the adhesion between the phenolic moulding powder a little less than, the mechanical strength of commutator product and hypervelocity performance can not further improve.
Summary of the invention:
In view of disadvantages of background technology, the purpose of this utility model aims to provide a kind of reasonable in design, in the time of can strengthening the commutator moulding and the adhesion between the phenolic moulding powder, improves the end commutator copper sheet of commutator product mechanical strength and hypervelocity performance.
The utility model takes following technical scheme to finish:
A kind of end commutator copper sheet comprises lamellar body and fixing feet, and the upper surface of lamellar body is a working face, and the lower surface of lamellar body is provided with the groove that combines with phenolic moulding powder, it is characterized in that: the two sides of lamellar body are laid with some little pits.The end commutator copper sheet of technique scheme, the two sides of lamellar body are laid with some little pits, the design of small rut makes the two sides of lamellar body become coarse relatively, so copper sheet when the commutator moulding and the adhesion between the phenolic moulding powder strengthen, and then effectively improved the mechanical strength and the hypervelocity performance of commutator product.
Described pit is the dome shape pit.Described fixing feet is provided with two up and down, forms oat tail groove structure between two fixing feet.In the technique scheme, the moulding process of dome shape pit is simple relatively, and the oat tail groove structure that forms between two fixing feet can strengthen the adhesion between copper sheet and the phenolic moulding powder.
Description of drawings:
The utility model has following accompanying drawing:
Fig. 1 is the structure chart of end commutator copper sheet,
Fig. 2 is the vertical view of Fig. 1.
Embodiment:
As shown in the figure, end commutator copper sheet of the present utility model, comprise lamellar body 1 and fixing feet 2, the upper surface 1a of lamellar body is a working face, the lower surface 1b of lamellar body is provided with the groove 4 that combines with phenolic moulding powder, and the two sides 1c of described lamellar body is laid with some little pits 5, and described pit 5 is the dome shape pit, described fixing feet 2 is provided with two up and down, forms oat tail groove structure 3 between two fixing feet 2.
End commutator copper sheet of the present utility model, because the two sides of lamellar body are laid with some little pits, the design of small rut makes the two sides of lamellar body become coarse relatively, when the commutator moulding, then strengthened and phenolic moulding powder between adhesion, thereby effectively improved the commutator product mechanical strength and the hypervelocity performance.
Claims (3)
