Detailed description of the invention
Embodiment 1
Fig. 1 indicates that the axonometric chart of the stator of the motor of embodiments of the present invention 1。
In FIG, the stator 100 of motor has: circular stator core 1, and it has such as 12 tooth (not shown) prominent to axis direction；It is arranged on the insulation division 2 on the tooth of stator core 1；The winding wire 3 of single Y type tie lines of the three-phase being wrapped on tooth by direct concentratred winding mode；3 lenticular wire terminals 4, are respectively inserted each square hole 2b of the tie lines side being arranged on insulation division 2, for supplying power supply to the winding wire 3 of single Y type tie lines of three-phase；Not shown neutral point terminal。
Stator core 1 is such as the electromagnetic steel plate that thickness is about 0.1～0.7mm to be struck out banding, by riveting (か め), welding, the stacking such as bonding, after the single Y type tie lines by implementing three-phase on the 12 of this stratification teeth, each tooth bends towards axle center and is formed as circular。
Insulation division 2 is such as to use the thermoplastic resins such as PBT (polybutylene terephthalate (PBT)), formed integrally with stator core 1, is arranged on each tooth。In addition it is also possible to after shaping insulation division 2, be assembled on tooth。In this case, insulation division 2 is divided into tie lines side and reef knot line side, they is inserted from the axial both ends of tooth respectively and constitutes insulation division 2。Insulation division 2 in tie lines side be provided with the magnet-wire of the winding wire 3 to each phase (U phase, V phase, W phase) guide required multiple pins, for substrate 10 being assembled into the jut 2a etc. of stator 100。On this substrate 10, circular hole 10b is set in the position relative with jut 2a。
Additionally, insulation division 2 in tie lines side, as mentioned above, the tie lines of winding wire 3 is single Y type tie lines of three-phase, thus the neutral point terminal that the other end of the magnet-wire of the winding wire 3 of 3 lenticular wire terminals 4 (being supplied to the terminal of power supply) of connecting of the one end being assembled with the magnet-wire of the winding wire 3 of each phase and each phase connects。Magnet-wire, lenticular wire terminal 4 and neutral point terminal make the coating film of magnet-wire melt by being referred to as melted heating, and the method for end and each terminal 4,5 by riveting fusing is mechanical and is electrically connected。
At the upper surface of the insulation division 3 being assembled with lenticular wire terminal 4, as it has been described above, be provided with OBL square hole 2b。Lenticular wire terminal 4 is the flat wire made of copper of such as width 1.5mm, thickness 0.5mm, implements the hot-dip of stannum in its surface。Lenticular wire terminal 4 electrically connects one end and the substrate 10 of the magnet-wire of the winding wire 3 of each phase。Additionally, although lenticular wire terminal 4 employs flat wire as an example, but as long as being lenticular wire。
Here, about the shape of the lenticular wire terminal 4 of present embodiment, use Fig. 2 and Fig. 3 to illustrate。
Fig. 2 indicates that the axonometric chart of the state that the lenticular wire terminal of embodiments of the present invention 1 inserts insulation division, and Fig. 3 indicates that the sectional view of the state that the lenticular wire terminal of embodiments of the present invention 1 inserts substrate。
Lenticular wire terminal 4 shown in Fig. 2 and Fig. 3 is formed through each operation shown below。Additionally, the order shaping each operation of lenticular wire terminal 4 is an example, it is not limited to this。
(1) press the middle body of the bar-shaped flat wire being admitted to and fix, cutting into the length of regulation。In addition it is also possible to cut off the end of any one party at the two ends of flat wire obliquely relative to the axis of flat wire。When cutting off an end obliquely, this is partially inserted into the square hole 2b of insulation division 2。
(2) when compressing the flat wire cut off, flat wire is bent with right angle (90 ° ± 10 °) in the position of regulation, shapes this flat wire while the same face becomes L-shaped。
(3) bend the sheet 4a of a side of the flat wire being bent into L-shaped with turning back with 180 ° in the position of regulation, relative with the 4a of this sheet own。Now, between the sheet 4a of a side of both sides, there is gap 4e。By this bending, this part is formed as wedge shape。The part of this wedge shape becomes substrate insertion section 4d, and the leading section of the sheet 4a of a side becomes insulation insertion section 4f。
(4) bend the end of the sheet 4b of the opposing party of the flat wire being bent into L-shaped with substantially 180 ° with turning back, shape lenticular wire terminal 4。This end becomes electric wire hook portion 4c。
In the lenticular wire terminal 4 shaped as described above, the insulation insertion section 4f of flat wire is inserted into the square hole 2b of insulation division 2。Now, the insulation insertion section 4f and substrate insertion section 4d of lenticular wire terminal 4 are on same axis, do not implement bending machining between which, from without the impact by machining deviation。It addition, will not cause that deviation occurs in the position of substrate insertion section 4d because of each lenticular wire terminal 4 such that it is able to easily carry out the insertion to substrate 2。
Be hooked with one end of the magnet-wire of winding wire 3 at the electric wire hook portion 4c of flat wire, by riveting, lenticular wire terminal 4 and winding wire 3 are connected via magnet-wire。On the other hand, the substrate insertion section 4d of flat wire is inserted into the square hole 10a (with reference to Fig. 1) being arranged at substrate 10。This substrate insertion section 4d is wedge shape, thus when being inserted into square hole 10a, because of the elasticity of kink, and the gap between the square hole 10a of substrate 10 diminishes。This gap diminishes, and thus, when welding substrate 10 and lenticular wire terminal 4, solder is difficult in flow on winding wire 3。
According to embodiment above 1, owing to the insulation insertion section 4f and substrate insertion section 4d of lenticular wire terminal 4 are on same axis, so becoming easy to the insertion of substrate 10。Thereby, it is possible to reduce the bad product of lenticular wire terminal 4。Further, since the machining accuracy of lenticular wire terminal 4 need not be improved, so cost will not be increased, it is possible to increase productivity ratio。
Additionally, owing to the substrate insertion section 4d of lenticular wire terminal 4 is formed as wedge shape, so when being inserted into square hole 10a, because of the elasticity of kink, and the gap between the square hole 10a of substrate 10 diminishes such that it is able to suppress solder the spilling to winding wire 3 when welding substrate 10 and lenticular wire terminal 4。

Fig. 4 indicates that the figure of the Sketch of the air conditioner of embodiments of the present invention 2。
Air conditioner 200 shown in figure is constituted by with lower component: have the indoor set 201 of indoor heat exchanger；Off-premises station 202, it is connected on indoor set 201 via refrigerant piping 203, and has outdoor use heat exchanger。Off-premises station 202 is provided with the blower-use motor (not shown) making fan 204 rotate, indoor set 201 is also equipped with the blower-use motor (not shown) making fan rotate。
In above-mentioned blower-use motor, as tdescribed in embodiment 1, employ there is the stator 100 not increasing cost and the good lenticular wire terminal 4 of productivity ratio。By this stator 100 is applicable to blower-use motor, it is possible to realize the raising of the quality of air conditioner 200。
