Description
Technical field
The invention relates to the brush assembly of electric of motor of dust collector, particularly the terminal brush assembly of electric of leaf spring and the integrated motor of dust collector of coil connecting terminal.
Background technology
Fig. 1 is the sectional arrangement drawing of motor of dust collector structure in the past, and Fig. 2 decomposes the oblique view of a brush assembly of electric part in the past.
In the past in the motor of dust collector, the inboard of motor frame 1 fixedly installs stator module 2 as shown in the figure, and the inboard of its stator module 2 rotatably is provided with rotor assembly 3.
And the top of motor frame 1 is combined with impeller frame 4, and its impeller frame 4 inboards are provided with on the axle that is connected rotor assembly 3 and rotor assembly 3 rotates the impeller 5 that sucks air together, and the place ahead of its impeller 5 is provided with impeller cover 6.
Among the figure, the Lower Half of motor frame 1, promptly the bottom radial direction of rotor assembly 3 is provided with most brush assembly of electric 7 to its rotor assembly 3 supplying electric currents.
Brush assembly of electric 7 is as shown in Figure 1 to Figure 3 by the brush holder 7a of secure bond in motor frame 1, insertion is fixed on the brush eyelid retractor 7b of brush holder 7a inside, slip be inserted in brush eyelid retractor 7b inner and its terminally be close to the brush 7c that the rotor assembly commutator comes delivered current, the brush spring 7d that resilient support brush 7c contacts all the time at the rotor assembly commutator brush 7c, support the terminal leaf spring 7e that brush spring 7d gives brush 7c delivered current, two ends are inserted the sub-7f of the coil connecting terminal that is combined in motor frame 1 and brush holder 7a separately and are constituted.
Above-mentioned motor of dust collector action is as follows.
That is, then rotor assembly 3 rotation and drive impeller 5 rotations that are combined in rotor assembly 3 of input current is drawn into motor frame 1 according to the rotation extraneous air of impeller 5 by impeller cover 6 and discharges by the outlet (not marking) at rear after inboard.
Here, the electric current that the process of scrutinizing input current then is applied to stator module 2 supplies on the brush 7c with leaf spring 7e by sub-7f of the coil connecting terminal of brush assembly of electric 7 and terminal, and the electric current that supplies to brush assembly of electric 7 forms electric closed cycle (loop) for rotor rotated assembly 3 sustainable supply electric currents.
But, in the brush assembly of electric of above-mentioned motor of dust collector in the past, because of terminal is made separately in addition of leaf spring 7e and the sub-7f of coil connecting terminal, so complex structure makes that unit price rises and reduce productivity ratio because of the increase of assembling procedure.
Summary of the invention
The present invention is that its objective is provides for the brush assembly of electric shortcoming invention that solves above-mentioned motor of dust collector: terminal comes simplified structure to reduce the brush assembly of electric of the motor of dust collector that the manufacturing unit price boosts productivity with leaf spring 7e and the sub-7f integral production of coil connecting terminal.
In order to achieve the above object, the brush assembly of electric of motor of dust collector of the present invention, its structure comprises the brush holder 11 on the motor frame that is fixed on housing stator assembly and rotor assembly, at the brush holder 11 inner brush eyelid retractors of fixing 12 that insert, slip is inserted in the brush eyelid retractor 12 and its end is close to the brush 13 that commutator comes delivered current, square end makes its brush spring that is close to above-mentioned commutator all the time 14 behind the resilient support brush, is fixed on the motor frame and connects the coil of stator module and the contact of its other end and support electric current that brush eyelid retractor 12 makes above-mentioned coil is delivered to brush by brush eyelid retractor 12 brush terminal 15.
Advantage and good effect: in the brush assembly of electric of motor of dust collector of the present invention, the terminal of brush delivered current forms the brush terminal with leaf spring and the sub-integral production of coil connecting terminal, so can simplify brush assembly of electric structure decrease number of components, and, boost productivity thus by these reduction manufacturing expenses, minimizing assembling procedure.

Embodiment
Below, illustrated embodiment describes the brush assembly of electric of motor of dust collector of the present invention in detail with reference to the accompanying drawings.
Fig. 3 is the oblique view that decomposes brush assembly of electric of the present invention, and Fig. 4 is the oblique view of assembling brush assembly of electric of the present invention, and Fig. 5 is the assembling section of brush assembly of electric of the present invention.
The brush assembly of electric of motor of dust collector of the present invention as shown in the figure, inboard with reference to Fig. 1 motor frame 1 fixedly installs stator module 2, the inboard of its stator module 2 rotatably is provided with rotor assembly 3, the top of motor frame 1 is combined with impeller frame 4, its impeller frame 4 inboards are provided with on the axle that is connected rotor assembly 3 and rotor assembly 3 rotates the impeller 5 that sucks air together, the place ahead of its impeller 5 is provided with impeller cover 6, the Lower Half of motor frame 1, promptly the bottom radial direction of rotor assembly 3 is provided with a plurality of brush assembly of electric 10 to its rotor assembly 3 supplying electric currents.
Brush assembly of electric 10 is as shown in Figure 3 by the brush holder 11 of secure bond in motor frame 1, insertion is fixed on the brush eyelid retractor 12 of brush holder 11 inside, slip is inserted in brush eyelid retractor 12 inner its ends and is close to the brush 13 that the rotor assembly commutator comes delivered current, resilient support brush 13 makes its brush 13 contact brush spring 14 at the rotor assembly commutator all the time, is connected with the coil (not shown) of stator module 10 when supporting brush eyelid retractor 12 to make its two ends be combined in brush terminal 15 formations of brush 13 and motor frame 1 separately.
Formation of non-conductive materials such as brush holder 11 usefulness plastics and secure bond are on motor frame 1, and conductive materials such as brush eyelid retractor 12 usefulness brass form and insert with the quadrangular barrel shape and are fixed in the brush holder 11 of above-mentioned motor frame 1.
