Abstract
The utility model discloses a grooved reverser, pressing including plastics and annotating casing and cell type switching -over piece, the excircle circumference equipartition setting of annotating the casing, its characterized in that are pressed at plastics to cell type switching -over piece: the left surface perpendicular to lamellar body direction of height of cell type switching -over piece is equipped with many left side recesses, and right flank perpendicular to lamellar body direction of height is equipped with many right side recesses, left side recess and right side recess symmetry set up, and the left side recess radially runs through the left surface of cell type switching -over piece lamellar body, and the right side recess radially runs through the right flank of cell type switching -over piece lamellar body. The utility model discloses can effectively improve product hypervelocity performance, the simultaneous system is done with low costsly.
Description
Technical field:
This utility model relates to commutator topology field, is specifically related to the improvement invention of a kind of tank commutator.
Background technology:
Diverter product mainly divides Hooked reverser, tank commutator and end commutator three kinds.For improving the hypervelocity performance of tank commutator product, first have to strengthen the adhesion between grooved commutator segment and plastic pressure injection housing during tank commutator molding, and this arranges what reinforcing ring realized generally by improving inside structure of hook of grooved commutator segment, quantity or diverter, rarely other method that can adopt, therefore can not better meet the rate request that electric tool is increasingly higher.
Summary of the invention:
In view of the deficiency of background technology, the purpose of this utility model aims to provide one can be effectively improved product hypervelocity performance, the tank commutator that cost of manufacture is low simultaneously.
This utility model has adopted the following technical scheme that:
A kind of tank commutator, including plastic pressure injection housing and grooved commutator segment, grooved commutator segment is arranged at the cylindrical circumference uniform distribution of plastic pressure injection housing, it is characterized in that: the left surface of described grooved commutator segment is perpendicular to lamellar body short transverse and is provided with a plurality of left groove, right flank is perpendicular to lamellar body short transverse and is provided with a plurality of right groove, and described left groove and right groove are symmetrical arranged.
Left groove extends radially through the left surface of grooved commutator segment lamellar body, and right groove extends radially through the right flank of grooved commutator segment lamellar body.
The tank commutator of technique scheme, it is provided with left and right sides groove in the left and right side of grooved commutator segment, the design of this left and right sides groove makes grooved commutator segment under the premise not changing profile and impact use, first save material and reduce own wt, cost of manufacture is made to reduce, the more important thing is that tank commutator plastic material when injection-compression molding can be sufficient filling with entering in groove and fill groove, make to be formed between grooved commutator segment with plastic pressure injection housing to be firmly combined, due to the enhancing of adhesion and alleviating of weight, thus being effectively increased the hypervelocity performance of tank commutator product, and then better meet the rate request that electric tool is increasingly higher.
Accompanying drawing illustrates:
This utility model has drawings described below:
Fig. 1 is shape assumption diagram of the present utility model,
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention:
As shown in the figure, a kind of tank commutator of the present utility model, including plastic pressure injection housing 1 and grooved commutator segment 2, grooved commutator segment 2 is arranged at the cylindrical circumference uniform distribution of plastic pressure injection housing 1, the left surface of described grooved commutator segment 2 is perpendicular to lamellar body short transverse and is provided with a plurality of left groove 3, left groove 3 extends radially through the left surface of grooved commutator segment 2 lamellar body, the right flank of described grooved commutator segment 2 is perpendicular to lamellar body short transverse and is provided with a plurality of right groove 4, right groove 4 extends radially through the right flank of grooved commutator segment 2 lamellar body, described left groove 3 and right groove 4 are symmetrical arranged, described left groove 3 and right groove 4 are triangle groove.
Above-mentioned tank commutator, when injection-compression molding, plastic material can be sufficient filling with entering in groove and fill groove, make to be formed between grooved commutator segment with plastic pressure injection housing to be more firmly combined, due to the enhancing of adhesion and alleviating of weight, thus being effectively increased the hypervelocity performance of tank commutator product, and then better meet the rate request that electric tool is increasingly higher.
