Abstract
The utility model discloses a kind of Hooked reverser copper sheet, comprise the main leaf body of top tape crotch and be located at two dovetail pin up and down of main leaf body medial surface, it is characterized in that: described main leaf body medial surface is also provided with one and half dovetail pin near the tip position of crotch, this half dovetail pin straight forming on main leaf body medial surface, the centre of described main leaf body is provided with the hollow out die cavity of bar shaped along main leaf body short transverse, this hollow out die cavity is provided with left and right opening to be run through outward from the left and right side of main leaf body, be provided with interior side opening to run through outward from the medial surface of main leaf body, interior side opening is positioned at the centre of upper and lower two dovetail pin.The utility model can greatly strengthen Hooked reverser shaping time and phenolic moulding powder between adhesion, reduce own wt simultaneously, thus effectively improve the hypervelocity performance of Hooked reverser product.
Description
Technical field:
The utility model relates to a kind of commutator, is specifically related to a kind of copper sheet of Hooked reverser.
Background technology:
Traditional Hooked reverser, the structure of what copper segment many times adopted is two dovetail pin, the adhesion of copper segment when Hooked reverser is shaping and between phenolic moulding powder of two dovetail leg structure is more weak; Also have, whom various equivalent modifications do not have can consider to improve adhesion between copper segment and phenolic moulding powder by the architecture advances of main leaf body, therefore the hypervelocity performance of Hooked reverser product can not improve to a certain extent further, better can not meet the more and more higher rate request of electric tool.
Summary of the invention:
In view of the deficiency of background technology, the purpose of this utility model aims to provide a kind of adhesion that can greatly strengthen between phenolic moulding powder, reduces own wt simultaneously, thus effectively improve Hooked reverser product hypervelocity performance Hooked reverser copper sheet.
The utility model takes following technical scheme:
Hooked reverser copper sheet, comprise the main leaf body of top tape crotch and be located at two dovetail pin up and down of main leaf body medial surface, it is characterized in that: described main leaf body medial surface is also provided with one and half dovetail pin near the tip position of crotch, this half dovetail pin straight forming on main leaf body medial surface, the centre of described main leaf body is provided with the hollow out die cavity of bar shaped along main leaf body short transverse, this hollow out die cavity is provided with left and right opening to be run through outward from the left and right side of main leaf body, be provided with interior side opening to run through outward from the medial surface of main leaf body, interior side opening is positioned at the centre of upper and lower two dovetail pin.
Have employed the Hooked reverser copper sheet of technique scheme, first, there are when Hooked reverser is shaping three dovetail pin simultaneously and phenolic moulding powder combines, and the one and half dovetail pin set up be positioned at main leaf body medial surface tip position and on main leaf body medial surface straight forming, so enhance the adhesion between copper segment and phenolic moulding powder; Also have, have employed the Hooked reverser copper sheet of technique scheme, unlike the prior art, it also by the architecture advances of the main leaf body to copper segment strengthen Hooked reverser shaping time and phenolic moulding powder between adhesion, its principle is: arrange hollow out die cavity in the centre of main leaf body, and hollow out die cavity is provided with left and right opening and interior side opening, when enabling commutator shaping, phenolic moulding powder is fully filled to enter in hollow out die cavity and formed between the main leaf body of copper segment and is firmly combined, and the setting of hollow out die cavity simultaneously reduces the weight of copper segment self.Due to the enhancing of adhesion and alleviating of weight, thus effectively improve the hypervelocity performance of Hooked reverser product, the hypervelocity performance of Hooked reverser product is further enhanced on the basis of existing technology, thus better meets the more and more higher rate request of electric tool.
Accompanying drawing illustrates:
Fig. 1 is side surface direction view of the present utility model.
Embodiment:
As shown in the figure, Hooked reverser copper sheet of the present utility model, comprise the main leaf body 7 of top tape crotch 5 and be located at two dovetail pin 1 up and down of main leaf body medial surface 7a, described main leaf body medial surface 7a is also provided with one and half dovetail pin 4 near the tip position of crotch 5, this half dovetail pin 4 straight forming on main leaf body medial surface 7a, the centre of described main leaf body 7 is provided with the hollow out die cavity 6 of bar shaped along main leaf body short transverse, this hollow out die cavity 6 is provided with left and right opening to be run through outward from the left and right side of main leaf body, be provided with interior side opening to run through outward from the medial surface 7a of 3 main leaf bodies, interior side opening 3 is positioned at the centre of upper and lower two dovetail pin 1.
