Abstract
The utility model discloses a high-strength commutator copper sheet which comprises a sheet body and two dovetail-shaped fixed pins; the two dovetail-shaped fixed pins are arranged up and down along the height direction of the sheet body; the high-strength commutator copper sheet is characterized in that each dovetail-shaped fixed pin is divided into two halves of dovetail vertically and the two halves of dovetail are bent externally to both sides of different directions. According to the high-strength commutator copper sheet, bonding force with bakelite powder can be enhanced, and the mechanical strength and the 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 high-intensity copper segment.
Background technology:
Be mechanical strength and the hypervelocity performance that promotes the commutator product, the general fixing feet structure of wanting emphasis to consider copper segment, the reasonable in design of having only fixing feet, just can make the adhesion between copper segment and the phenolic moulding powder strong, and have only the adhesion that strengthens between copper segment and the phenolic moulding powder, could promote the mechanical strength and the hypervelocity performance of commutator product.Present a kind of copper segment is made up of lamellar body and two dove-tail form fixing feet, and two dove-tail form fixing feet are along the short transverse upper and lower settings of lamellar body.Above-mentioned copper segment, fixing feet be by dovetail have barb-like strengthen and phenolic moulding powder between adhesion, not much else, the mechanical strength of commutator product and the hypervelocity performance can not further get a promotion.
Summary of the invention:
In view of disadvantages of background technology, the purpose of this utility model aims to provide the adhesion between a kind of energy enhancing and the phenolic moulding powder, promotes the high strength copper segment of commutator product mechanical strength and hypervelocity performance.
The utility model takes following technical scheme to finish:
A kind of high strength copper segment, form by lamellar body and two dove-tail form fixing feet, two dove-tail form fixing feet are along the short transverse upper and lower settings of lamellar body, it is characterized in that: every dove-tail form fixing feet is from the above-below direction dovetail into two that is divided into two, and the two halves dovetail has carried out outwardly-bent to the both sides of different directions.From the top-direction of lamellar body, the two halves dovetail after outwardly-bent is V-shaped.
The copper segment of technique scheme, every dove-tail form fixing feet is from the above-below direction dovetail into two that is divided into two, and the two halves dovetail has carried out outwardly-bent to the both sides of different directions, play after the two halves dovetail is outwardly-bent and the essentially identical technique effect of dovetail barb, so, combining between every fixing feet and the phenolic moulding powder be equivalent to original twice in conjunction with effect, so strengthened the adhesion between copper segment and the phenolic moulding powder, promoted the mechanical strength and the hypervelocity performance of commutator product.
Description of drawings:
The utility model has following accompanying drawing:
Fig. 1 is the structure chart of high strength copper segment,
Fig. 2 is the left view of Fig. 1,
Fig. 3 is the vertical view of Fig. 2.
Embodiment:
As shown in the figure, high strength copper segment of the present utility model, form by lamellar body 1 and two dove-tail form fixing feet 2, two dove-tail form fixing feet 2 are along the short transverse upper and lower settings of lamellar body 1, every dove-tail form fixing feet 2 is from the above-below direction dovetail (first dovetail 2a and second dovetail 2b) into two that is divided into two, and the two halves dovetail has carried out outwardly-bent to the both sides of different directions, from the top-direction of lamellar body 1, shown in Figure 3, first dovetail 2a and second dovetail 2b after outwardly-bent are V-shaped.
High strength copper segment of the present utility model, every dove-tail form fixing feet is from the above-below direction dovetail into two that is divided into two, and the two halves dovetail has carried out outwardly-bent to the both sides of different directions, play after the two halves dovetail is outwardly-bent and the essentially identical technique effect of dovetail barb, combining between every fixing feet and the phenolic moulding powder be equivalent to original twice in conjunction with effect, so strengthened the adhesion between copper segment and the phenolic moulding powder, promoted the mechanical strength and the hypervelocity performance of commutator product.
Claims (2)
1. high strength copper segment, form by lamellar body and two dove-tail form fixing feet, two dove-tail form fixing feet are along the short transverse upper and lower settings of lamellar body, it is characterized in that: every dove-tail form fixing feet is from the above-below direction dovetail into two that is divided into two, and the two halves dovetail has carried out outwardly-bent to the both sides of different directions.
