Components for motor wiring and motors equipped with such components

The present invention relates to a component for connecting motors, in particular to a component for connecting electric motors of home appliances such as air conditioner fan drives, and a motor equipped with the component.

In recent years, motors have been required to reduce costs and man-hours. In order to meet these strict requirements, motors equipped with wiring components as circuit boards have been widely used. Hereinafter, such a conventional motor will be described.

FIG. 3(a) described later shows a cross-sectional view of such a motor, especially a die-casting motor. Fig. 3(b) is a perspective view showing a stator assembly provided with wiring members for the motor shown in Fig. 3(a) before resin molding. Fig. 3(c) is a sectional view along line A-A of the wiring board in Fig. 3(b). In the figure, the rotor 24 is supported by the bearing 23 so as to be freely rotatable, the stator core 21 is disposed on the periphery of the rotor 24, and a predetermined gap is maintained between the outer peripheral surface of the rotor 24, and the coil 25 is wound on the bobbin 22. In the multiple slots of the stator core 21. The wiring board 26 is a component that surrounds the conductive metal 19 with a synthetic resin 18 and forms an integral part. The wiring board 26 is supported on the coil 25 with a bobbin 22, so that the coil 25 fuses and other burnout protection devices 27 and are used to communicate with the coil 25. The connecting portion of the lead wire 28 connected to the external electrical circuit is exposed to the outside. Carry out the assembling of rotor 24, the stator core 21 that has been wound on the coil and terminal board 26, after finishing the assembly of stator assembly (structure shown in Fig. 3 (b)), the exterior of this stator assembly is carried out with motor exterior molding resin. Die casting, made of Figure 3 (a) shown in the motor.

Fig. 4 shows an example of a wiring board as a conventional wiring part. As shown in Fig. 4 (a), the conventional wiring part is formed on a phenolic paper or a synthetic material substrate and forms a circuit board 8 and a bonding area (ラソド) by a conductive material. ) 9 of the printed circuit board 10, the terminal part 11 and the printed circuit board 10 for winding the electromagnetic wire 4 from the stator (not shown) are integrated, and as shown in Figure 4 (b), the electromagnetic wire 4 is wound On the terminal portion 11, it is fixed to the terminal portion 11 by soldering.

However, since the manufacture of such printed circuit boards requires specialized technology, and most of the manufacturing equipment is expensive and large-scale, the manufacturing equipment is required to be cheap and versatile.

In order to solve such a problem, as shown in FIG. 5, a conductive material such as a brass plate is press-worked, and the circuit board 12 is punched out (FIG. 5(a)), so that the circuit board 12 remains on the circuit board 12. In the state of the terminal part 13, the circuit board 12 is die-cast (Fig. 5(b)) with a synthetic resin 14 to eliminate unnecessary places 15 and form a wiring part (Fig. 5(c)), as shown in Fig. 6 As shown, the magnet wire 4 is wound around the terminal portion 13 and fixed to the terminal portion 13 by brazing.

However, since the wiring member as shown in FIG. 6 is a result of punching through press working as shown in FIG. 5, because it is a thin plate, edges 16, 17. Therefore, when the magnet wire 4 is wound on the terminal portion 13, the magnet wire 4 will be cut by the edges 16 and 17, and especially when the magnet wire has a small diameter, it is easy to cause a disconnection. .

Therefore, the present invention was established to solve the above-mentioned problems, and an object of the present invention is to provide a connecting member capable of preventing disconnection failure and a motor including the member.

In order to achieve the above object, the motor wiring part of the present invention is provided with a terminal plate having a conductive magnet wire terminal portion for winding a magnet wire on its outer side, and on the terminal plate, adjacent to the terminal portion, integrally Synthetic resin protruding parts are formed, and the magnet wire is wound around the protruding part and the terminal part at the same time, and fixed to the terminal part by brazing, thereby providing a motor connection component that does not cause disconnection failure. and motors with this part.

According to the present invention, since there is provided a terminal block having a terminal portion of a conductive magnet wire for winding a magnet wire on its outer side, and a protruding portion made of synthetic resin is integrally formed on the terminal plate adjacent to the terminal portion, The magnet wire can be wound around the projection of synthetic resin by winding the magnet wire around the protrusion and the terminal at the same time, and fixing it to the terminal by brazing. Accordingly, the magnet wire can be fixed to the terminal portion by soldering without being cut or damaged.

A brief description of the attached drawings,

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 shows an embodiment of the present invention motor wiring part, and Fig. 1 (b), (c) show the form when carrying out magnet wire winding,

The difference from the wiring member shown in FIG. 6 is that a synthetic resin protrusion 2 is integrally formed on the terminal board 3, and is brought close to the terminal part 1, and the magnet wire is connected between the protrusion 2 and the terminal part 1. 4. The winding is fixed to the terminal part by brazing.

According to this configuration, the magnet wire 4 can be wound around the terminal portion 1 without cutting or damaging the magnet wire 4 .

Even if this embodiment uses a structure punched out of a conductive material on the wiring board, it goes without saying that the present invention is applicable to such occasions where edges are generated on the terminal portion. In addition, due to the application of punching, the The terminal portion is thin, and a defect such as disconnection of the magnet wire is likely to occur. However, according to the present embodiment, even with such a thin plate, the defect of disconnection does not occur.

In addition, in this embodiment, since the resin molding is adopted, the surface of the wiring board is covered with a resin member 5 except for the terminal portion 1 as an electrical connection portion, and the protrusion 2 is integrally formed on the synthetic resin member 5, so that The present invention provides a component for motor connection with a simple structure.

In addition, by forming the outer periphery of the terminal portion 1 into a smooth shape, it is possible to better prevent disconnection.

In addition, in the above, the winding of the magnet wire starts from the terminal portion, but it is also possible to start from the protrusion. If the winding starts from the protrusion, the work can be facilitated, the work efficiency is good, and automation can be easily realized.

At this time, even if the magnet wire 4 is disconnected due to the facing edges on the protruding portion 2, since the magnet wire 4 is fixed to the terminal portion 1 by soldering, a disconnection defect will not be caused.
