Embodiment
Below, with reference to the preferred implementation of description of drawings DC brushless motor of the present invention.
Embodiment 1
As shown in Figures 1 and 2, the DC brushless motor 1 of one embodiment of the invention has stator 2 and rotor 3, and stator 2 is made of iron core 4 and winding 5, and rotor 3 is made of iron core 6, permanent magnet 7 and armature spindle 8.In addition, dispose control circuit substrate 9 from Control current to stator 2 that supply with.
In DC brushless motor 1, the means that couple together as printed wiring portion with end of the winding 5 of stator 2 and control circuit substrate 9, as shown in Figures 2 and 3, use two apertures that closely perforate goes out in printed wiring portion and the lead 10 of high rigidity.
The both ends of approximate right angle bending wire 10 make an end 10a pass an aperture, and from the outstanding suitable length in the surface of control circuit substrate 9.
And, an end of at one end twining winding 5 on the protuberance of the 10a of portion, the crooked protuberance of approximate right angle and make it behind the surface of control circuit substrate 9 carries out soldering 11 to an end of winding 5 and is fixed on the protuberance.
The pars intermedia 10b of lead 10 and the inner surface butt of control circuit substrate 9 make the other end 10c of lead 10 pass another aperture, and outstanding from the surface of control circuit substrate 9.
And, the other end 10c is carried out soldering 12 is fixed in the printed wiring portion that is formed at control circuit substrate 9 inner surfaces.
As shown in Figure 3, in above-mentioned winding method of attachment, the protuberance of one end 10a of approximate right angle bending wire 10 and make its surface along control circuit substrate 9, thus the height H 1 from the upper surface of control circuit substrate 9 to the upper end of the protuberance of an end 10a is lower than the height of the winding method of attachment of in the past use pin.Therefore, the thickness of attenuate housing 13 greatly, the result can make DC brushless motor 1 self slimming.
In addition, to the other end 10c a suitable segment distance is arranged from the protuberance of an end 10a of lead 10, thereby on protuberance, twine an end of winding 5, and when carrying out soldering 11, even some is overheated, heat can not be delivered in order to be fixed on the control circuit substrate 9 morely has yet carried out on the scolding tin of soldering 12, does not have the danger that melts soldering tin, lead 10 are thrown off from control circuit substrate 9.
And lead 10 is lower than pin 60 prices, so even use multiple conducting wires 10 for the printed wiring portion of end of the winding 5 that connects stator 2 and control circuit substrate 9, also can reduce cost of parts fully, the price of DC brushless motor 1 is reduced.
In addition, can be further the pars intermedia 10b of lead 10 be become approximate right angle ground bending repeatedly, make it be passed in 2 above apertures in a plurality of apertures that perforate goes out on the control circuit substrate 9.
If make such structure, thermal diffusion when more effectively making soldering is on control circuit substrate 9, not carried out on the scolding tin of soldering 12 so heat can not be delivered in order being fixed on the control circuit substrate 9, not had the danger that melts soldering tin, lead 10 are thrown off from control circuit substrate 9.
As Fig. 4 and shown in Figure 5, the DC brushless motor 31 of another embodiment of the present invention, except the syndeton of the printed wiring portion of end of the winding 5 of stator 2 and control circuit substrate 39, all the other are identical with the structure of above-mentioned DC brushless motor 1.
Below, the component parts mark same reference numerals identical with DC brushless motor 1 described.
In DC brushless motor 31,,, use the extension 40a that prolongs printed wiring portion 40 and form as Fig. 5 and shown in Figure 6 as the means that the printed wiring portion with end of the winding 5 of stator 2 and control circuit substrate 39 couples together.
Periphery at control circuit substrate 39 forms notch part 41, and printed wiring portion 40 is extended in this notch part 41, forms the extension 40a that has stretched out suitable length.
And an end of twining winding 5 on the extension 40a of printed wiring portion 40 is carried out soldering 42 to an end of winding 5 and is fixed on the extension 40a.
As shown in Figure 6, in above-mentioned winding method of attachment, extension 40a prolongs printed wiring portion 40 and forms, the surface of the surface of extension 40a and control circuit substrate 39 is positioned at on the one side, thereby from the upper surface of control circuit substrate 39 to extension 40a by the height H 3 of the upper end of the part of soldering 42, more be lower than the height in the winding method of attachment of DC brushless motor 1.Therefore, the thickness of attenuate housing 43 greatly, the result can make DC brushless motor 31 self slimming.
In addition, since when not being connected to control circuit substrate 39 in a end with winding 5 between members such as the pin between them 60, leads 10, so on the extension 40a of printed wiring portion 40, twine an end of winding 5, and when carrying out soldering 42, even it is overheated to produce, do not have the problem that intermediary's member is thrown off from control circuit substrate 39 yet.
And, owing to do not need intermediary's members such as pin 60, lead 10, thus can more reduce cost of parts, the price of DC brushless motor 31 is reduced.
