Embodiment

Below, the execution mode of motor of the present invention is described in detail based on accompanying drawing.

Fig. 1 is the partial sectional view of the motor of execution mode, and Fig. 2 is the vertical view of the terminal board represented from top view Fig. 1, and Fig. 3 amplifies the vertical view representing and be located at the pipe fixed part of the terminal board of Fig. 1, and Fig. 4 is the cutaway view of the pipe fixed part shown in Fig. 3.

As shown in Figure 1, the motor 1 of present embodiment comprises: framework 2; Bracket 3; Stator 4, it is pressed into and is fixed on framework 2 and bracket 3; Rotor 5, it has the inner side being inserted into stator 4 with gap; Terminal board 7, it has compartment of terrain and is configured on the coil 6 of stator 4; Three wires 8 be such as connected with the terminal (not shown) being located at insulator 10; And wire outlet 9, it runs through and is located at bracket 3.

Framework 2 and bracket 3 utilize flange 2a, 3b of being located at both and combine.Stator 4 circumferentially has the multiple teeth portion 4a correspondingly arranged with number of poles, and by the insulator 10,11 of the upper end and bottom of being located at teeth portion 4a, and is clipped in the middle by insulator 10,11 and the coil 6 being wound in teeth portion 4a is formed.

Rotor 5 is integrated with the rotating shaft 14 being supported on bearing 12,13 in rotatable mode, and rotates together with rotating shaft 14 under the effect of the rotating magnetic field produced at the coil 6 of stator 4, and this bearing 12,13 is installed on framework 2 and bracket 3.

The through hole of the flange 3a that wire outlet 9 is provided at distance bracket 3 toroidal of the position of A separated by a distance, and lining 15 is installed.Article three, wire 8 is inserted in protection tube 16, and is externally drawn by wire outlet 9 together with protection tube 16.Protection tube 16 in bracket 3 is tied band 17 and ties up and be fixed on the pipe fixed part 20 being located at terminal board 7.In addition, protection tube 16 fixing in employ strapping 17, but to be not limited thereto, such as, also can with sleeve line etc. protection tube 16 to be tied up and be fixed on pipe fixed part 20.

Above-mentioned terminal board 7 is formed as ring-type as shown in Figure 2.Terminal board 7 part relative with wire outlet 9 is in the circumferential provided with breach 30, and installs above-mentioned pipe fixed part 20 in this breach 30.Terminal board 7 loads and is fixed on the two side of the insulator 10 of the upper end of the teeth portion 4a being located at stator 4.As shown in Figure 4, terminal board 7 is fixed by being engaged with the pawl carrier 10a of sidewall of the outer circumferential side being located at insulator 10 by the multiple claw 7a being located at periphery.

The internal perisporium 7b of terminal board 7 and the sidewall of both sides of the circumference being located at breach 30 are such as molded as one by pipe fixed part 20.That is, pipe fixed part 20 is shaping integratedly with terminal board 7.As shown in Figure 3, Figure 4, pipe fixed part 20 has: protrusion tab 22, and it exports 9 sides from horizontal part 21 guiding line and gives prominence to, and this horizontal part 21 at right angles extends from the internal perisporium 7b of terminal board 7 and the two side 31 of breach 30; Vertical plate 23, it at right angles bends downwards from the top of protrusion tab 22; And jut 24, it is located at the two ends in the bight of protrusion tab 22.The height of vertical plate 23 is formed longer than the thickness of strapping.This is to make strapping 17 easily by between pipe fixed part 20 and coil 6.The top ends of vertical plate 23 is connected to the upper end of the periphery wall of insulator 10.Above-mentioned jut 24 is arranged to prevent strapping 17 from departing from.

As described above, make three wires 8 by protection tube 16 and be fixed on pipe fixed part 20 with strapping 17, the top ends forming the vertical plate 23 of pipe fixed part 20 is connected to the upper end of the periphery wall of insulator 10.Utilize this structure, winding three wires 8 when manufacturing motor, when installing other products, reduce the stress putting on three wires 8.Thus be difficult to depart from and colory motor 1 therefore, it is possible to provide a kind of coupling part of three wires 8 can not be applied in stress (tensile stress).

In addition, owing to being only make three wires 8 by protection tube 16 and be fixed on pipe fixed part 20 with strapping 17, the required number of components that therefore connects up is less, manufacturing cost can be suppressed for lower.In addition, owing to being provided with jut 24 at pipe fixed part 20, the strapping 17 therefore tying up protection tube 16 can not depart from pipe fixed part 20.

In addition, in the present embodiment, the position of flange 3a wire outlet 9 being located at distance bracket 3 A separated by a distance, that is, make the position that the position of wire outlet 9 becomes lower than pipe fixed part 20, but be not limited thereto.Such as, the flange 3a that also as shown in Figure 5 the position of wire outlet 9 can be located at distance bracket 3 separates the position of the distance B higher than distance A.In addition, Fig. 5 is the partial sectional view of the motor of the variation representing execution mode.

In this case, make the position that the position of wire outlet 9 becomes higher than pipe fixed part 20, but due to as described above, terminal board 7 is fixed on insulator 10, therefore, it is possible to provide a kind of coupling part of three wires 8 can not be applied in stress (tensile stress) and colory motor by multiple claw 7a with the engaging of pawl carrier 10a.
