Abstract
The utility model discloses a high-strength commutator copper sheet, which consists of a sheet body and two dovetail type fixing pins, wherein the two dovetail fixing 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 fixing pin is divided into two thin sheets in the middle of the thickness direction; and the two thin sheets bend outwards respectively. According to the high-strength commutator copper sheet, the binding force with bakelite powder can be enhanced, and the mechanical strength and the over-speed 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:
The high strength copper segment, form by lamellar body and two dove-tail form fixing feet, two dove-tail form fixing feet is characterized in that along the short transverse upper and lower settings of lamellar body: every dove-tail form fixing feet is divided into two into two thin slices from the centre of thickness direction, and two thin slices are outwardly-bent separately.From the top-direction of lamellar body, two thin slices after outwardly-bent are V-shaped.
The copper segment of technique scheme, every dove-tail form fixing feet has been carried out burst and bending, burst and bending are played 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 divided into two into two thin slices (left thin slice 2b and right thin slice 2a) from the centre of thickness direction, and two thin slices are outwardly-bent separately, from the top-direction of lamellar body 1, shown in Figure 3, left thin slice 2b and right thin slice 2a after outwardly-bent are V-shaped.
High strength copper segment of the present utility model, every dove-tail form fixing feet has been carried out burst and bending, burst and bending are played and the essentially identical technique effect of dovetail barb, combining between every dove-tail form 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.
