Embodiment
Below, with reference to accompanying drawing, embodiments of the present invention are described.
(execution mode)
Fig. 1 is the sectional view of the motor of embodiments of the present invention.As shown in Figure 1, motor 1 comprises molding stator 2 and rotor 3.Molding stator 2 by utilize heat-curing resin by stator core 5 and printed circuit board (PCB) 8 integrally formed and formed.At this, be wound with armature coil 4 at stator core 5.At printed circuit board (PCB) 8, the microcomputer software write connector 7 as multiple electronic unit is installed.In addition, rotor 3 rotates centered by rotating shaft 3a, is relatively held in bearing 19 with stator core 5.
In the end of the armature coil 4 of stator core 5, be bonded to terminal pins 6 outstanding on the rotating shaft direction 3b of rotating shaft 3a.Terminal pins 6 and printed circuit board (PCB) 8 utilize solder to be electrically connected.For printed circuit board (PCB) 8, clip from the back side, front by circuit shell 9a, 9b as cover except terminal pins insertion section 10.At circuit shell 9b, be provided with the dismounting portion 11 of the part dismounting enabling to expose from molding stator 2.
Here, after a pair circuit shell 9a, 9b cover printed circuit board (PCB) 8, stator core 5 and printed circuit board (PCB) 8 utilize resin integrally formed and form molding stator 2.In addition, a pair circuit shell 9a, 9b have the exposed portion 9c exposed from molding stator 2.And a part of exposed portion 9c by dismounting, the printed circuit board (PCB) 8 of exposed portion 9c is provided with microcomputer software write connector 7 from printed circuit board (PCB) 8.In addition, terminal pins 6 and printed circuit board (PCB) 8 are electrically connected at connecting portion 20 by solder.Further, a pair circuit shell 9a, 9b are arranged in the mode avoiding connecting portion 20.
Fig. 2 is the front view of the printed circuit board (PCB) of the motor of embodiments of the present invention.As shown in Figure 2, microcomputer software write connector 7 be arranged on shown in Fig. 1 from the printed circuit board (PCB) 8 that molding stator 2 exposes.
Fig. 3 is the front view with the printed circuit board (PCB) of cover of the motor of embodiments of the present invention.As shown in Figure 3, circuit shell 9b cover is installed on the whole of multiple electronic units of printed circuit board (PCB) 8.
In addition, circuit shell 9b is configured in the position avoiding terminal pins insertion section 10.Further, the terminal pins 6 shown in Fig. 1 is inserted into printed circuit board (PCB) 8 from terminal pins insertion section 10.
Sectional view when Fig. 4 is the resin injection molding of the motor of embodiments of the present invention.As shown in Figure 4, in the resin inflow region 18 in mould 15a, 15b, be configured with among stator core 5 and printed circuit board (PCB) 8 and resin will be utilized to carry out the part of molding.When injection mo(u)lding, circuit shell 9a, 9b become wall, and a part for printed circuit board (PCB) 8 is not resin moulded.Namely a part for printed circuit board (PCB) 8 is by circuit shell 9a, 9b cover.
Fig. 5 A is the sectional view with the motor of the cover being provided with jog of the motor of embodiments of the present invention, and Fig. 5 B is the details drawing in the A portion of Fig. 5 A.As shown in Fig. 5 A, Fig. 5 B, the composition surface of circuit shell 9a, 9b forms the concavo-convex shape of a pair.Such as, circuit shell 9b forms the shape of protuberance 12a.Circuit shell 9a forms the shape of recess 12b.Like this, the side among a pair circuit shell 9a, 9b is provided with protuberance 12a, and the opposing party is provided with recess 12b.In addition, printed circuit board (PCB) 8 is provided with the hole 8a for making protuberance 12a through.
The hole 8a of through like this printed circuit board (PCB) 8 and outstanding protuberance 12a is embedded into recess 12b.Consequently, improve the constant intensity of circuit shell 9a, 9b and printed circuit board (PCB) 8, and improve the effect of the intrusion of the inside preventing moulding resin to circuit shell 9a, 9b.
Fig. 6 A is the sectional view with the motor of the cover of the variation being provided with jog of the motor of embodiments of the present invention, and Fig. 6 B is the details drawing in the B portion of Fig. 6 A.As shown in Fig. 6 A, Fig. 6 B, be coated with filler 13 at the junction surface 21 of circuit shell 9a, 9b and printed circuit board (PCB) 8.In addition, the junction surface 21 being coated with filler 13 is close to rotating shaft 3a side and any one party away from rotating shaft 3a side.Consequently, the adhesion of circuit shell 9a, 9b and printed circuit board (PCB) 8 improves, and improves the effect of the intrusion of the inside preventing moulding resin to circuit shell 9a, 9b.
Fig. 7 A is the sectional view at the cover of the motor of embodiments of the present invention with the motor at L angle, and Fig. 7 B is the details drawing in the C portion of Fig. 7 A.As shown in Figure 7 A, 7 B, circuit shell 9a, 9b are connected by L-shaped flange 14 with printed circuit board (PCB) 8 respectively.Consequently, the pressure that moulding resin puts on junction surface 21 is relaxed, and becomes the motor 1 that pressure that opposing mold resin causes is stronger.
As shown in Fig. 5 A, Fig. 5 B ~ Fig. 7 A, Fig. 7 B, due to during by the injection molded molding stator 2 of heat-curing resin, block moulding resin by circuit shell 9a, 9b, therefore the pressure of resin is not applied in printed circuit board (PCB) 8.Therefore, the electronic unit more weak to pressure tolerance is had at printed circuit board (PCB) 8 by the partial configuration of circuit shell 9a, 9b cover.Consequently, when the injection molded of resin, molding condition is not controlled, and forms electronic circuit by the motor 1 configured integratedly.
In addition, as shown in Figure 1, microcomputer software write connector 7 is arranged at the printed circuit board (PCB) 8 that exposes from molding stator 2.Further, a part of the circuit shell 9b near microcomputer software write connector 7 is formed can the dismounting portion 11 of dismounting.Consequently, after by molding, whether such as, when arranging air-supply arrangement without and there occurs fault, it is motor 1 that microcomputer software write connector 7 can be utilized to investigate failure cause.And after molding, because when microcomputer software write connector breaks down, the overriding of microcomputer software easily can be carried out.
In addition, the motor 1 of embodiments of the present invention situation about arranging in adverse circumstances more with dust is without many.Therefore, need to make microcomputer software write connector 7 not expose, utilize safeguard measures such as covering lid.In addition, circuit shell 9a, 9b are arranged in the mode covered by the whole electronic units being installed on printed circuit board (PCB) 8.Consequently, do not need to arrange circuit shell 9a, 9b to each electronic unit, reduce the component count of circuit shell 9a, 9b, thus reduce the installation work-hour of circuit shell 9a, 9b.
In addition, circuit shell 9a, 9b are arranged in the mode avoiding terminal pins 6 connecting portion.Consequently, even if circuit shell 9a, 9b are from after printed circuit board (PCB) 8 clips by the back side, front, also by solder, terminal pins 6 can be connected with printed circuit board (PCB) 8.
In addition, in the motor 1 of embodiments of the present invention, a part for printed circuit board (PCB) 8 is clipped from the back side, front by circuit shell 9a, 9b.But, even if printed circuit board (PCB) 8 entirety is covered from the back side, front also can obtain same effect.
In addition, as the example of the electronic unit more weak to pressure tolerance covered by circuit shell 9a, 9b, can being the electrolytic capacitor for absorbing power supply noise, noise filter, the microcomputer that can adjust the performance of motor and detector unit, can not being covered by circuit shell 9a, 9b as to the resistance etc. of the stronger parts of pressure tolerance.
