The content of the invention

The invention problem to be solved

However, in above-mentioned existing technology, needing to be kept with second by the first maintaining part in addition to terminal board, connector The cloth wire maintainer that portion is constituted, accordingly, there exist constitute the number of components increase of motor, cause this class of the increase of manufacturing cost Topic.In addition, it is necessary to electric wire is winding on cloth wire maintainer in existing technology, need to work there is also wiring operation and This problem of time.

The present invention completes to solve that above-mentioned problem, its object is to obtain wiring operation easily and wire Connection be difficult to depart from, manufacturing cost can be suppressed to relatively low motor.

Solve the technical scheme of problem

The motor of the present invention includes：Stator；Rotor, its rotary magnetic produced by the coil of teeth portion of stator is wound in Rotated in the presence of together with rotary shaft；Terminal board, it has compartment of terrain configuration on the coil of stator, the terminal board tool There is terminal, the terminal is bonded to multiple wires；And protection pipe, it is inserted for wire；Protection pipe is fixed on terminal board.

Invention effect

According to the present invention, due to the protection pipe inserted with wire is fixed on into terminal board, therefore wiring operation is easily, wire Connection be difficult to depart from.Further, since the part that only protection pipe inserted with wire is fixed on needed for terminal board, therefore wiring Manufacturing cost, can be suppressed to relatively low by negligible amounts.

Embodiment

Hereinafter, the embodiment of the motor of the present invention is described in detail based on accompanying drawing.

Fig. 1 is the partial sectional view of the motor of embodiment, and Fig. 2 is to represent to bow from the terminal board that Fig. 1 is observed in top View, Fig. 3 is top view of the enlarged representation located at the pipe fixed part of Fig. 1 terminal board, and Fig. 4 is the pipe fixed part shown in Fig. 3 Sectional view.

As shown in figure 1, the motor 1 of present embodiment includes：Framework 2；Bracket 3；Stator 4, it is pressed into and is fixed on frame Frame 2 and bracket 3；Rotor 5, it has the inner side for being inserted into stator 4 with gap；Terminal board 7, it has compartment of terrain configuration fixed On the coil 6 of son 4；Three wires 8 being for example connected with the terminal (not shown) located at insulator 10；And wire outlet 9, its Run through and be located at bracket 3.

Framework 2 is combined with bracket 3 using flange 2a, 3b located at both.Stator 4 circumferentially has with number of poles correspondingly Multiple teeth portion 4a of arrangement, and by the insulator 10,11 of the upper end located at teeth portion 4a and bottom, and by insulator 10th, 11 it is clipped in the middle and is wound in teeth portion 4a coil 6 and constitute.

Rotor 5 is integrated with the rotary shaft 14 that bearing 12,13 is supported in the way of rotating freely, and in the line of stator 4 Rotated in the presence of rotating excitation field produced by circle 6 together with rotary shaft 14, the bearing 12,13 is installed on framework 2 and bracket 3.

Wire outlet 9 is provided at the through hole of the flange 3a of distance bracket 3 toroidal of A position separated by a distance, and is provided with Bushing 15.Three wire 8 is inserted into protection pipe 16, and is drawn together with protection pipe 16 by wire outlet 9 to outside.Support Protection pipe 16 in frame 3 is tied band 17 and ties up and be fixed on the pipe fixed part 20 located at terminal board 7.In addition, in protection pipe 16 Fixation in used strapping 17, but be not limited to this, such as can also with sleeve line protection pipe 16 is tied up and solid Due to pipe fixed part 20.

Above-mentioned terminal board 7 is formed as ring-type as shown in Figure 2.In the circumferential relative with wire outlet 9 of terminal board 7 Part is provided with breach 30, and installs in the breach 30 above-mentioned pipe fixed part 20.Terminal board 7 is loaded and is fixed on located at stator 4 Teeth portion 4a upper end insulator 10 two side.As shown in figure 4, terminal board 7 passes through located at multiple claws of periphery 7a engages and fixed with the pawl carrier 10a of the side wall of the outer circumferential side located at insulator 10.

The internal perisporium 7b of terminal board 7 and the side wall of the circumferential both sides located at breach 30 are for example shaped to by pipe fixed part 20 One.That is, pipe fixed part 20 and terminal board 7 is integrally formed.As shown in Figure 3, Figure 4, pipe fixed part 20 has：Protrusion tab 22, It exports 9 sides from the guiding line of horizontal part 21 and protruded, and the horizontal part 21 is at right angles from the internal perisporium 7b and the two of breach 30 of terminal board 7 Side wall 31 extends；Vertical plate 23, it at right angles bends downwards from the top of protrusion tab 22；And jut 24, it is located at prominent The two ends in the corner of slice 22.The height of vertical plate 23 is formed must be longer than the thickness of strapping.This is in order that strapping 17 holds Easily by between pipe fixed part 20 and coil 6.The top ends of vertical plate 23 are connected to the upper end of the periphery wall of insulator 10.On Jut 24 is stated to prevent that strapping 17 from departing from and sets.

As described above, make three wires 8 by protection pipe 16 and be fixed on pipe fixed part 20 with strapping 17, form pipe The top ends of the vertical plate 23 of fixed part 20 are connected to the upper end of the periphery wall of insulator 10.Using the structure, in manufacture electricity During motivation, winding three wires 8 during other products are installed, the stress for putting on three wires 8 is reduced.Therefore, it is possible to provide one The coupling part of kind of three wires 8 will not be applied in stress (tensile stress) thus be difficult to depart from and motor best in quality 1。

Further, since being only to make three wires 8 by protection pipe 16 and be fixed on pipe fixed part 20 with strapping 17, therefore Number of components needed for wiring is less, can be suppressed to manufacturing cost relatively low.Further, since being conformed with pipe fixed part 20 Portion 24, therefore the strapping 17 of protection pipe 16 is tied up without departing from pipe fixed part 20.

In addition, in the present embodiment, by wire outlet 9 located at the flange 3a A separated by a distance of distance bracket 3 position, i.e. Making the position of wire outlet 9 turns into the position lower than pipe fixed part 20, but is not limited to this.For example, it is also possible to such as Fig. 5 institutes Show and like that separate the position of wire outlet 9 higher than apart from the A position apart from B located at the flange 3a of distance bracket 3.In addition, Fig. 5 It is the partial sectional view of the motor for the variation for representing embodiment.

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