Conventionally, a motor in which a terminal pin is held by an insulator is known (for example, see patent document 1).
Hereinafter, the motor will be described with reference to fig. 8.
As shown in fig. 8, the conventional motor includes: an insulator 102 for forming an insulating layer on the surface of the stator core 101; a winding 103 wound around the stator core 101 via an insulator 102; and a molded body 104 that integrally molds them. Here, the terminal pins are held by the insulating material 102, the winding end portions are bundled at the bases of the terminal pins and electrically connected thereto, and the tip ends of the terminal pins are exposed from the mold body 104. A printed circuit board 105 built in the motor is electrically connected to terminal pins exposed from the mold body 104.
Here, in order to expose the tip of the terminal pin from the mold body 104, when the mold is brought into contact with the insulating material 102 in the integral molding, the winding end portion is sandwiched and the wire breakage occurs. Therefore, only the tip of the terminal pin is brought into contact with the molding die, and the molding material does not flow into the tip of the terminal pin. Alternatively, after the molding material is poured into the tip of the terminal pin and molded, the tip of the terminal pin is exposed from the molded body by removing the molding material from the tip of the terminal pin.
Further, there is a motor having a protective member for exposing the tip of the terminal pin from the molded body (see, for example, patent document 2).
Hereinafter, the motor will be described with reference to fig. 9 and 10.
As shown in fig. 9, the related art motor includes: an insulator 202 having an insulating layer formed on the surface of the stator core 201; a winding 203 wound around the stator core 201 via an insulator 202; and a molded body 204 in which they are integrally molded. Here, as shown in fig. 10, the terminal pin 205 is held by the insulating material 202, the winding end portion 206 is bundled at the base of the terminal pin 205 and electrically connected thereto, the protective member 207 is inserted into the terminal pin 205 at a portion closer to the winding end bundled portion than the winding end bundled portion, and the tip end of the terminal pin protruding from the protective member 207 is exposed from the mold body 204.
By providing the protective member 207, the tip of the terminal pin can be prevented from coming into contact with the mold and the molding material can be prevented from flowing into the tip of the terminal pin when the terminal pin is integrally molded. Thus, the stator can be easily arranged in the mold during molding, and the molded terminal pin does not require processing such as removal of the molding material from the tip end thereof.

In addition, when only the top surface is shown, the top side of fig. 1 is shown, and when only the bottom surface is shown, the bottom side of fig. 1 is shown.
The shaft 11 constitutes a rotation shaft J of the rotor 7, and 2 bearings 12a and 12b are provided on the top surface side and the bottom surface side (vertical direction in fig. 1) of the rotor 7, respectively.
The bearings 12a and 12b are rotatably held around the shaft 11 as a central axis.
The stator 2 includes a stator core 15, an insulator 3, a winding 4, a terminal portion 8, a molded body 6, and a bracket 13, and is disposed on the outer periphery of the rotor 7.
The stator core 15 is formed in a hollow cylindrical shape, and a through hole 52 is provided in a wall portion of the cylindrical shape from the top surface to the bottom surface. In the present embodiment, the upper side of fig. 1 is defined as the top surface of the stator 2, and the lower side is defined as the bottom surface of the stator 2. The stator core 15 is disposed such that an inner peripheral surface 54 formed in a circular shape in a hollow cylindrical shape faces an outer peripheral surface of the rotor 7.
The through holes 52 are provided at equal intervals in the circumferential direction, and the insulator 3 is inserted from the top surface side and the bottom surface side so as to cover the inner surface of the through hole 52.
The insulators 3 are made of an insulating material, and are wound with the windings 4 in a state of being inserted into the stator core 15. Further, the insulator 3 has a protruding portion 9 protruding from the top surface toward the outer peripheral side on the top surface side of the stator core 15. As shown in fig. 2, in the present embodiment, the insulating member 3 has at least 1 protruding portion 9.
The protrusion 9 holds the terminal portion 8, and the terminal portion 8 penetrates the protrusion 9 in parallel with the rotation axis direction. The terminal portion 8 has an exposed end portion 8a on the top surface side (upper side in fig. 1) of the protruding portion 9 and a molded end portion 8b on the bottom surface side (lower side in fig. 1) of the protruding portion 9. Further, the 1 protruding portion 9 may have a plurality of terminal portions 8.
The winding 4 is wound around the stator core 15 via the insulator 3. The winding end portion 4a (end portion) of the winding 4 is connected to the molded end portion 8b of the terminal portion 8 by being bundled.
The molded body 6 integrally molds the stator core 15, the insulator 3, the winding 4, and the molded end portion 8b of the terminal portion 8. The exposed end portion 8a of the terminal portion 8 is exposed from the mold 6. Examples of the material of the molded body 6 include thermosetting resins.
The printed circuit board 5 is disposed on the exposed end portion 8a side of the terminal portion 8 and connected to the exposed end portion 8 a. The printed circuit board 5 is connected to a power source so that the winding 4 is energized. Further, the molded end portion 8b is provided at a position facing the printed circuit board 5 via the protruding portion 9.
The terminal portion 8 is made of a conductive material, and may be formed in a rectangular tube shape, a cylindrical shape, or a so-called plate shape having a wide front side with respect to a side surface having a small thickness.
In such an arrangement, the top-side opening of the molded body 6 is press-fitted and sealed by the holder 13, and the outer peripheries of the 2 bearings 12a and 12b are fixed to the molded body 6 and the holder 13, whereby the rotor 7 is rotatably fixed to the stator 2.
Here, in order to insulate the printed circuit board 5 from the holder 13, an insulating film 10 is disposed so as to cover the printed circuit board 5 from the top surface side. Further, a drive IC (Integrated Circuit) 14 for driving the motor 1 is mounted on the printed Circuit board 5, and the drive IC14 generates heat during driving. In order to efficiently dissipate heat of the driver IC14 to the chassis 13, an insulating heat sink 16 is interposed between the driver IC14 and the chassis 13.
The above is the structure of the motor 1.
Next, a process of manufacturing the molded body 6, that is, a process of integrally molding the insulating material 3, the winding 4, and the molded end portion 8b of the terminal portion 8 with a resin and exposing the exposed end portion 8a of the terminal portion 8 from the molding will be described with reference to fig. 4, 5, and 6.
Fig. 4 is a sectional view showing a mold for molding according to an embodiment of the present invention. Fig. 5 is a sectional view showing a state in which a stator is disposed in the mold X shown in fig. 4. Fig. 6 is a sectional view showing a state where a stator is disposed in a mold. In fig. 4 to 6, the top surface side shown in fig. 1 to 3 is the lower side of the respective drawings, and the bottom surface side is the upper side of the respective drawings. In fig. 6, hatching is omitted in some portions for simplification.
The mold for molding includes a mold X and a mold Y. The mold X includes a first mold portion 22 and a second mold portion 23.
The first mold portion 22 is a portion for integrally curing the top surfaces of the stator core 15, the insulator 3, and the winding 4 and the molded end portion 8b of the terminal portion 8.
The second mold portion 23 is engaged with the first mold portion 22, and the second mold portion 23 is not in contact with the exposed end portion 8a of the terminal portion 8 but in contact with the top surface 9a of the protruding portion 9 so as to provide a space around the terminal portion 8. The top surface 9a is in contact with the second mold portion 23 over the entire circumference of the terminal portion 8. That is, the top surface 9a and the second mold portion 23 are in contact with each other without a gap, and the exposed end portion 8a cannot be contacted (injected) with the thermosetting resin.
The mold Y is a portion for integrally curing the bottom surfaces of the stator core 15, the insulator 3, and the winding 4.
The first mold portion 22 and the second mold portion 23 are described as separate bodies, but may be an integral mold.
First, the stator 2 is disposed at a predetermined position of the mold X. A core rod 21 is provided in the center of the die X, and the outer diameter of the core rod 21 matches the inner diameter of the stator core 15. That is, the stator 2 is disposed so that the outer periphery of the core rod 21 faces the inner periphery of the stator core 15. In this state, the top surface 9a of the protruding portion 9 of the stator 2 faces the second mold portion 23. The stator 2 is held in a state in which the exposed end 8a of the terminal portion 8 is not in contact with the second mold portion 23 and the top surface 9a of the protruding portion 9 is in contact with the second mold portion 23.
In the holding state, the concave portion 23c of the second mold portion 23 is provided so as to form the gap 8c around the terminal portion 8 between the second mold portion 23 and the terminal portion 8, whereby the arrangement of the mold X to the stator 2 becomes easy.
Next, after the stator 2 is disposed, the mold Y is disposed. In a state where the mold Y is disposed, an internal space formed by the mold X and the mold Y is closed. Further, a gate 24, which is an opening portion for injecting a molding material, is disposed at a side portion of the mold Y.
Here, when the winding end portion 4a is connected to the top surface 9a side of the protruding portion 9, that is, the exposed end portion 8a, the winding end portion 4a may be pinched between the second mold portion 23 and the top surface 9a of the protruding portion 9 and broken. In order to avoid disconnection and to prevent the second mold portion 23 from coming into contact with the top surface 9a of the protrusion 9, the exposed end portion 8a of the terminal portion 8 is opened to the internal space formed by the mold X and the mold Y, and the molding material is filled into the exposed end portion 8 a.
Therefore, as in the embodiment of the present invention, the winding overhang 4a is connected to the molded overhang 8b of the terminal portion 8, and the second mold portion 23 can be brought into contact with the top surface 9a of the protrusion 9 without breaking the winding overhang 4 a.
In this state, a molding material that is a thermosetting resin is pressed from the gate 24. The molding material is pressed into and filled in the internal space formed by the mold X and the mold Y by the pressing of the molding material. The stator core 15, the insulator 3, the protruding portion 9, the winding 4, and the molded end portion 8b of the terminal portion 8 are integrally cured and formed by the molded body 6 cured from a molding material by the first mold portion 22. Here, since the second mold portion 23 is not in contact with the exposed end portion 8a of the terminal portion 8 but in contact with the top surface 9a of the protrusion 9, the exposed end portion 8a of the terminal portion 8 can be exposed from the mold without using a protective member while preventing the mold material from filling the exposed end portion 8a of the terminal portion 8.
Next, a modified example of the structure of the terminal portion 8 will be described.
Fig. 7A and 7B are plan views showing the relationship between the exposed end portion and the molded body.
As shown in fig. 7A, the exposed end portion 8a may be exposed from the plurality of independent openings 81, 82, 83 of the molded body 6.
Accordingly, since only the vicinity of the terminal portion 8 is exposed from the mold 6, the number of portions of the protruding portion 9 covered by the mold increases, and a stronger structure can be obtained.
As shown in fig. 7B, the exposed end portion 8a may be exposed from the same opening 84 of the mold body 6.
This has the effect of simplifying the shape of the second mold portion 23 in which the end portion 8a is exposed.

Thus, the exposed end portion exposed from the molded body is positioned on the printed circuit board side disposed on the top surface side, and therefore, the effect of facilitating connection between the printed circuit board and the exposed end portion can be achieved.
In addition, the motor may be configured to include a plurality of protruding portions.
This makes it easy to bind the winding end portions of the respective phases to the molded end portions without touching the winding end portions, and therefore, the workability is improved.
The exposed end portions may be exposed from the plurality of openings of the molded body.
This structure exposes only the vicinity of the terminal portion from the mold, and therefore, the number of portions of the protruding portion covered by the mold increases, which can provide an effect of forming a stronger structure.
Further, the exposed end portion may be exposed from the same opening of the molded body.
This can provide an effect of simplifying the shape of the mold for forming the exposed end portion.
The molded article may be a thermosetting resin.
Accordingly, the thermosetting resin, once thermally cured, remains in a solid state even when heated again, and has excellent heat resistance and insulation properties, and thus can exhibit an effect of excellent long-term stability.
