Embodiment
Execution mode 1
Fig. 1 is the stereogram that represents the stator of the motor of execution mode 1 of the present utility model.
In Fig. 1, the stator 100 of motor has: circular stator core 1, and it has for example 12 teeth (not shown) outstanding to axis direction; Be arranged on the insulation division 2 on the tooth of stator core 1; By directly concentrating winding mode to be wrapped in the winding wire 3 of single Y type tie lines of the three-phase on tooth; 3 lenticular wire terminals 4, are inserted into respectively each square hole 2b of the tie lines side that is arranged on insulation division 2, for winding wire 3 supply powers of the single Y type tie lines to three-phase; Not shown neutral point terminal.
Stator core 1 is to be for example that the electromagnetic steel plate of about 0.1～0.7mm strikes out band shape by thickness, by riveted joint (か め), welding, bonding etc. stacked, implement single Y type tie lines of three-phase on 12 teeth by this stacked formation after, each tooth bends towards axle center and is formed as circular.
Insulation division 2 is for example to use PBT(polybutylene terephthalate (PBT)) etc. thermoplastic resin, be shaped integratedly with stator core 1, be arranged on each tooth.In addition also can, 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, and they are inserted and formation insulation division 2 from the axial both ends of tooth respectively.The magnet-wire that is provided with the winding wire 3 to each phase (U phase, V phase, W phase) at the insulation division 2 of tie lines side guides required multiple pins, for substrate 10 being assembled into jut 2a of stator 100 etc.On this substrate 10, in the position relative with jut 2a, circular hole 10b is set.
In addition, at the insulation division 2 of tie lines side, as mentioned above, the tie lines of winding wire 3 is single Y type tie lines of three-phase, thereby is assembled with 3 lenticular wire terminal 4(that one end of the magnet-wire of the winding wire 3 of each phase connects and is supplied to the terminal of power supply) the neutral point terminal that is connected with the other end of the magnet-wire of the winding wire 3 of each phase.Magnet-wire, lenticular wire terminal 4 and neutral point make the coating film fusing of magnet-wire by being called as the heating of melting with terminal, the method for the end of melting by riveted joint and each terminal 4,5 is mechanical and be electrically connected.
Being assembled with the upper surface of insulation division 3 of lenticular wire terminal 4, as mentioned above, be provided with OBL square hole 2b.Lenticular wire terminal 4 is for example flat wires made of copper of width 1.5mm, thickness 0.5mm, has implemented in its surface the hot-dip of tin.Lenticular wire terminal 4 is electrically connected one end and the substrate 10 of the magnet-wire of the winding wire 3 of each phase.In addition, although lenticular wire terminal 4 has used flat wire as an example, as long as lenticular wire.
Here about the shape of the lenticular wire terminal 4 of present embodiment, use Fig. 2 and Fig. 3 to describe.
Fig. 2 is the stereogram that represents the lenticular wire terminal of execution mode 1 of the present utility model to insert the state of insulation division, and Fig. 3 is the cutaway view that represents the lenticular wire terminal of execution mode 1 of the present utility model to insert the state of substrate.
Lenticular wire terminal 4 shown in Fig. 2 and Fig. 3 is formed through each operation shown below.In addition, the order of each operation of shaping lenticular wire terminal 4 is an example, 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 also can cut off obliquely with respect to the axis of flat wire, the end of any one party at the two ends of flat wire.In the situation that cutting off obliquely an end, this part is inserted into the square hole 2b of insulation division 2.
(2) compressing under the state of cut off flat wire, by flat wire in the position of regulation with right angle (90 ° ± 10 °) bending, on the same face, become L font and be shaped this flat wire.
(3) in the position of regulation with 180 ° of bending sheet 4a that are bent into a side of the flat wire of L font in the ground that turns back, 4a own is relative with this sheet.Now, between both sides' a side's sheet 4a, 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 a side sheet 4a becomes insulation insertion section 4f.
(4) with the bending end that is bent into the opposing party's of the flat wire of L font sheet 4b, the 180 ° of ground that turns back roughly, shaping lenticular wire terminal 4.This end becomes the electric wire hook 4c of portion.
In the lenticular wire terminal 4 being 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 of lenticular wire terminal 4 and substrate insertion section 4d, on same axis, do not implement bending machining between them, thereby can not be subject to the impact of machining deviation.In addition, can not there is not deviation because each lenticular wire terminal 4 causes the position of substrate insertion section 4d, thereby can easily carry out to the insertion of substrate 2.
Have one end of the magnet-wire of winding wire 3 at the electric wire hook 4c of portion of flat wire hook, by riveted joint, 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(that is arranged at substrate 10 with reference to Fig. 1).This substrate insertion section 4d is wedge shape, thereby in the time being inserted into square hole 10a, because of the elasticity of kink, and gap smaller between the square hole 10a of substrate 10.This gap smaller, thus, when welding substrate 10 and lenticular wire terminal 4, scolder is difficult to flow on winding wire 3.
According to above execution mode 1, because the insulation insertion section 4f of lenticular wire terminal 4 and substrate insertion section 4d are on same axis, so become easy to the insertion of substrate 10.Thus, can reduce the bad product of lenticular wire terminal 4.In addition, owing to not needing to improve the machining accuracy of lenticular wire terminal 4, so can not increase cost, can boost productivity.
In addition, because the substrate insertion section 4d of lenticular wire terminal 4 is formed as wedge shape, so while being inserted into square hole 10a, because of the elasticity of kink, and the gap smaller between the square hole 10a of substrate 10, thereby scolder the spilling to winding wire 3 can be suppressed at welding substrate 10 and lenticular wire terminal 4 time.
Execution mode 2
Fig. 4 is the figure that represents the Sketch of the air conditioner of execution mode 2 of the present utility model.
Air conditioner 200 shown in figure is by forming with lower member: the indoor set 201 with indoor heat exchanger; Off-premises station 202, it is connected on indoor set 201 via refrigerant piping 203, and has outdoor use heat exchanger.In off-premises station 202, be provided with the blower-use motor (not shown) that fan 204 is rotated, in indoor set 201, be also provided with the blower-use motor (not shown) that makes fan rotation.
In above-mentioned blower-use motor, as tdescribed in embodiment 1, use and there is the stator 100 that does not increase cost and the good lenticular wire terminal 4 of productivity ratio.By this stator 100 is applicable to blower-use motor, can realize the raising of the quality of air conditioner 200.
