Abstract
The utility model discloses a hook-type commutator copper sheet which comprises a sheet body and a fixed pin; one end of the sheet body is provided with a hook; the hook-type commutator copper sheet is characterized in that only one fixed pin is arranged in parallel with the sheet body and is a strip-shaped body; the fixed pin and the sheet body are connected through a rib; and at least five small windows are formed on the rib along the height direction of the sheet body. According to the hook-type commutator copper sheet, the overall strength is high, meanwhile the bonding force with bakelite powder is enhanced when a commutator is formed, 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 hook commutator.
Background technology:
The commutator product mainly divides three kinds of hook commutator, tank commutator and end commutators.The intensity of the mechanical strength of hook commutator product and hypervelocity performance and copper segment itself has relation, and while and commutator adhesion between copper sheet, the phenolic moulding powder when injection mo(u)lding have great relation, and above-mentioned two aspects all involve the structure problem of copper sheet.Present hook copper segment comprises lamellar body and fixing feet, and lamellar body one end is provided with crotch, and fixing feet is provided with two or three mostly, and every fixing feet is a swallowtail shape.The deficiency that said structure exists is: the copper sheet bulk strength is not high, simultaneously when the commutator moulding and the adhesion between the phenolic moulding powder also 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 bulk strength height, simultaneously when the commutator moulding and the adhesion between the phenolic moulding powder strengthen, improve the hook copper segment of commutator product mechanical strength and hypervelocity performance.
The utility model takes following technical scheme to finish:
A kind of hook copper segment, comprise lamellar body and fixing feet, lamellar body one end is provided with crotch, it is characterized in that: fixing feet is to be parallel to the bar shape of lamellar body and only to establish one, fixing feet is connected by rib with lamellar body, and rib upper edge lamellar body short transverse offers five little windows at least.Hook copper segment after the employing technique scheme, self structure compactness, bulk strength improve, a plurality of wickets of offering on the rib then make copper sheet when the commutator moulding and the adhesion between the phenolic moulding powder strengthen, because adhesion strengthens between copper sheet self bulk strength height and copper sheet and the phenolic moulding powder, so promoted effective raising of commutator product mechanical strength and hypervelocity performance jointly.
Described wicket is the rectangle window, and the length of rectangle window is suitable with the width of rib.The inward at both ends of described rib is shunk and is formed the arc groove that is lower than the fixing feet two ends.In the technique scheme, big length of window design and arc groove design can both 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 hook copper segment,
Fig. 2 is the vertical view of Fig. 1.
Embodiment:
As shown in the figure, hook copper segment of the present utility model, comprise lamellar body 1 and fixing feet 2, lamellar body 1 top is provided with crotch 6, described fixing feet 2 is also only established one for the bar shape that is parallel to lamellar body 1, the cross section of fixing feet 2 is a dovetail shaped, fixing feet 2 is connected by rib 3 with lamellar body 1, rib 3 upper edge lamellar body short transverses offer seven little windows 4, described wicket 4 is the rectangle window, the width of the length of rectangle window and rib 3 substantially quite is slightly less than the rib width, not only increased but also can not weaken copper sheet self intensity with the bonded area of phenolic moulding powder, the inward at both ends of described rib 3 is shunk and is formed the arc groove 5 that is lower than the fixing feet two ends, and the setting of arc groove 5 has also increased the bonded area of copper sheet and phenolic moulding powder.
Hook copper segment of the present utility model, self bulk strength height, when the commutator moulding, then strengthened and phenolic moulding powder between adhesion, thereby effectively improved the mechanical strength and the hypervelocity performance of commutator product.
Claims (3)
1. hook copper segment, comprise lamellar body and fixing feet, lamellar body one end is provided with crotch, it is characterized in that: fixing feet is to be parallel to the bar shape of lamellar body and only to establish one, fixing feet is connected by rib with lamellar body, and rib upper edge lamellar body short transverse offers five little windows at least.
2. a kind of hook copper segment according to claim 1 is characterized in that: described wicket is the rectangle window, and the length of rectangle window is suitable with the width of rib.
