[0005] Patent Document 1: Japanese Patent Application No. 2015-516797 Summary of the Invention

[0006] Problems to be solved by the invention

[0007] In the above-mentioned conventional motor, if the MAG-MATE plate terminal is unexpectedly deformed or moved due to the pressure of the resin during injection molding, for example, the contact area between the MAG-MATE portion and the MAG-MATE terminal becomes smaller, and the contact resistance may increase.

[0008] The present invention provides a motor, a compressor, and a fan motor capable of suppressing an increase in contact resistance between terminals.

[0009] Means for solving problems

[0010] A motor according to one embodiment of the present invention is characterized in that the motor includes:

[0011] an annular stator core;

[0012] a coil wound around the teeth of the stator core;

[0013] a first terminal electrically connected to the coil;

[0014] a receiving portion for receiving the first terminal; and

[0015] The second terminal, at least a portion of which is inserted into the first terminal accommodated in the accommodation portion,

[0016] The second terminal has an electrical connection portion, which is inserted into the first terminal and electrically connected to the first terminal.

[0017] The housing portion includes a first restricting portion that restricts movement of a portion of the second terminal other than the electrical connecting portion in a circumferential direction of the stator core.

[0018] According to the present invention, since the portion of the second terminal other than the electrically connected portion inserted into the first terminal is restricted from moving circumferentially around the stator core, unintended movement of the second terminal relative to the first terminal and deformation caused by such movement are less likely to occur. This prevents changes in the contact state between the first and second terminals, which could reduce the contact area. Consequently, an increase in contact resistance between the first and second terminals can be suppressed.

[0019] In one embodiment, the housing portion includes a housing portion body for housing the first terminal.

[0020] The first restricting portion is a protrusion protruding from the housing portion body.

[0021] In one embodiment, the housing portion includes a second restricting portion that restricts movement of a portion of the second terminal other than the electrical connecting portion in at least one direction in the axial direction of the stator core.

[0022] According to the above embodiment, the second limiting portion restricts movement of the portion of the second terminal, excluding the electrical connection portion inserted into the first terminal, in at least one direction of the stator core axial direction. This reduces the likelihood of unintended movement of the second terminal relative to the first terminal or deformation caused by such movement. This prevents changes in the contact state between the first and second terminals, which could reduce the contact area. Consequently, an increase in contact resistance between the first and second terminals can be suppressed.

[0023] In one embodiment,

[0024] The second terminal is bent at the bent portion.

[0025] The second terminal includes a wiring connection portion provided on the opposite side of the electrical connection portion relative to the bent portion.

[0026] The first restriction portion is provided at a position in the housing portion closer to the wiring connection portion than to the bent portion.

[0027] In the above embodiment, since the electrical connection portion is inserted into the first terminal, when a circumferential force acts on the wiring connection portion side of the second terminal, the portion of the second terminal on the wiring connection portion side tends to move about the bent portion. According to the above embodiment, since the first limiting portion is provided closer to the wiring connection portion than to the bent portion, the movement of the portion of the second terminal on the wiring connection portion side or deformation caused by such movement can be suppressed compared to a case where the first limiting portion is provided closer to the bent portion than to the wiring connection portion.

[0028] A motor according to one embodiment includes an insulator mounted on the stator core.

[0029] The housing portion is integrally provided with the insulator.

[0030] A compressor according to another aspect of the present invention includes:

[0031] the aforementioned motor; and

[0032] A compression mechanism driven by the motor.

[0033] A fan motor according to another embodiment of the present invention includes:

[0034] the aforementioned motor; and

[0035] A fan driven by the above motor. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 In FIG. 1 , the right half shows an external view of the motor 1 as viewed from the central axis direction, and the left half shows a cross-sectional view of the motor 1 taken along a cross section perpendicular to the central axis direction.

[0046] Reference Figure 1 The motor 1 of this embodiment is a so-called outer rotor type three-phase AC motor and includes an annular stator 2 and an annular rotor 3 disposed so as to surround the stator 2 .

[0047] In the following description, "axial direction" may refer to the direction of the central axis of the motor 1, "radial direction" may refer to the radial direction centered on the central axis C of the motor 1, and "circumferential direction" may refer to the circumferential direction centered on the central axis C of the motor 1. In this embodiment, the central axis of the stator 2 and the central axis of the rotor 3 coincide with the central axis C of the motor 1. In other words, the terms "axial direction," "radial direction," and "circumferential direction" may refer to the "axial direction," "radial direction," and "circumferential direction" of the stator 2 or the rotor 3, respectively.

[0048] The stator 2 includes an annular stator core 10, a plurality of coils 20 (twelve in this embodiment) wound around the stator core 10, and a plurality of insulators 30 (twelve in this embodiment) disposed between the stator core 10 and the coils 20. Although not shown, the stator 2 is resin-molded by coating it with BMC (Bulk Molding Compound) resin, a thermosetting resin material.

[0049] The stator core 10 is formed of laminated steel plates made of a conductive soft magnetic material and includes an annular back yoke 11 and a plurality of (twelve in this embodiment) teeth 12 extending radially outward from the outer circumference of the back yoke 11 .

[0050] The stator core 10 is composed of a plurality of (twelve in this embodiment) stator core blocks 10P connected in the circumferential direction. One tooth 12 is provided on each stator core block 10P.

[0051] The coil 20 is a copper wire covered with an insulating material such as an enamel resin, and is wound around the teeth 12 of the stator core 10 with the axis along the radial direction serving as the winding axis.

[0052] The insulator 30 is formed of an insulating resin material and insulates the stator core 10 from the coil 20 so that the current flowing through the coil 20 is not transmitted to the stator core 10 .

[0053] The stator 2 of this embodiment is composed of a plurality of (twelve in this embodiment) stator units 2U connected in the circumferential direction. Each stator unit 2U includes one stator core block 10P, one coil 20 , and one insulator 30 .

[0054] The rotor 3 has a cylindrical shape and is rotatably arranged radially outside the stator 2. The rotor 3 is multi-polarly magnetized so that north poles and south poles are alternately arranged in the circumferential direction.

[0055] Figure 2 This is an exploded perspective view of the stator unit 2U of this embodiment. Figure 2 In the example, the coil 20 is omitted. Figure 1 ) as shown in the figure.

[0056] Reference Figure 2 As described above, the stator unit 2U includes the stator core block 10P, the insulating member 30 covering a portion of the stator core block 10P, and the coil 20 wound around the teeth 12 of the stator core block 10P ( Figure 1 In addition, the stator unit 2U has a coil 20 ( Figure 1 As shown in FIG. 1 , a first terminal 40 electrically connected to the first terminal 40 and a second terminal 50 inserted into and engaged with the first terminal 40 are provided.

[0057] The insulator 30 is provided with: a first side ( Figure 2 and the first insulator 31 mounted on the other axial side of the stator core block 10P ( Figure 2 The first insulator 31 and the second insulator 32 are attached to the stator core block 10P so as to cover the teeth 12 of the stator core block 10P.

[0058] The first insulator 31 includes a housing portion 60 for housing the first terminal 40. The housing portion 60 of this embodiment is box-shaped with a bottom and is integrally provided with the first insulator 31. The housing portion 60 is provided at the radially inner end of the first insulator 31.

[0059] The first terminal 40 is a female terminal made of conductive metal. The first terminal 40 is housed in the housing portion 60 provided in the first insulator 31. In addition, the first terminal 40 has a female terminal for connecting to the coil 20 ( Figure 1The first terminal 40 is electrically connected to the coil 20 by engaging the lead wire (not shown) led out of the coil 20 and the receiving portion 42.

[0060] The second terminal 50 is a male terminal made of conductive metal and corresponds to the first terminal 40, which is a female terminal. The second terminal 50 is L-shaped and bent at a bend 51. The second terminal 50 includes a wiring connection portion 52 connected to the wiring 70 and an electrical connection portion 53 electrically connected to the first terminal 40. The wiring connection portion 52 is located on the side of the bend 51 opposite the electrical connection portion 53. The second terminal 50 also includes a plate-like flat portion 54 extending from the bend 51 toward the wiring connection portion 52.

[0061] The second terminal 50 is inserted and connected to the first terminal 40. Specifically, the electrical connection portion 53 is inserted and fitted into the receiving portion 42 of the first terminal 40, thereby connecting the second terminal 50 and the first terminal 40. Thus, the first terminal 40 and the second terminal 50 are electrically connected.

[0062] Figure 3 : is a perspective view showing the periphery of the storage portion 60 of this embodiment. Figure 3 , the second terminal 50 is indicated by a two-dot chain line.

[0063] Reference Figure 3 The storage portion 60 of this embodiment includes: a storage portion main body 61; a side from the storage portion main body 61 toward the axial direction (at Figure 3 and a pair of second limiting portions 63 provided in the storage portion body 61.

[0064] The housing body 61 has a substantially rectangular parallelepiped shape. The housing body 61 is provided with a holding hole 61 a for housing and holding the first terminal 40. An opening is formed in the upper surface 61 b of the housing body 61 through the holding hole 61 a.

[0065] A slit 61d is provided on a radially outer side surface 61c of the housing body 61. The slit 61d is formed so as to communicate with the holding hole 61a.

[0066] The pair of first restricting portions 62 of this embodiment is formed from the upper surface 61b of the housing body 61 toward one side in the axial direction (at Figure 3The pair of first restricting portions 62 are positioned radially outward from the retaining hole 61a. Furthermore, the pair of first restricting portions 62 are spaced apart in the circumferential direction. More specifically, the pair of first restricting portions 62 are positioned on either side of the circumferential direction, separated by a gap 61d provided in the housing body 61. Furthermore, the pair of first restricting portions 62 are integrally formed with the housing body 61.

[0067] The pair of first limiting portions 62 of this embodiment limit the circumferential movement of the second terminal 50. Specifically, the first limiting portion 62 limits the circumferential movement of the portion (for example, the flat plate portion 54) of the second terminal 50 other than the portion (specifically, the electrical connection portion 53) inserted and fitted into the first terminal 40 (see Figure 3 arrow A).

[0068] In this embodiment, the electrical connection portion 53 of the second terminal 50 is engaged with the first terminal 40 and fixed thereto. Therefore, if a circumferential force acts on the wiring connection portion 52 of the second terminal 50, the portion of the second terminal 50 that is closer to the wiring connection portion 52 than the curved portion 51 attempts to move circumferentially with the curved portion 51 as the base point. When the portion of the second terminal 50 that is closer to the wiring connection portion 52 attempts to move circumferentially with the curved portion 51 as the base point, the first limiting portion 62 interferes with the flat plate portion 54 of the second terminal 50, thereby limiting such movement. Thus, when a circumferential force acts on the wiring connection portion 52 of the second terminal 50, the first limiting portion 62 suppresses deformation of the second terminal 50.

[0069] The pair of second restricting portions 63 in this embodiment are platform-shaped and disposed on the housing body 61. The second restricting portions 63 are arranged to protrude from a pair of inner surfaces 61e of the housing body 61, which define a gap 61d. In other words, the second restricting portions 63 are arranged to protrude into the gap 61d. The pair of second restricting portions 63 are arranged to oppose each other and spaced apart in the circumferential direction. Each of the pair of second restricting portions 63 has a restricting surface 63a.

[0070] The second limiting portion 63 limits the second terminal 50 from moving to one side in the axial direction ( Figure 3 Specifically, the second limiting portion 63 limits the movement of the portion of the second terminal 50 (for example, the flat plate portion 54) other than the portion inserted into and fitted into the first terminal 40 (specifically, the electrical connection portion 53) toward one side in the axial direction.

[0071] In this embodiment, as described above, the electrical connection portion 53 of the second terminal 50 is fitted and fixed to the first terminal 40. Therefore, when the wiring connection portion 52 of the second terminal 50 acts on one side (in the axial direction) Figure 3When a force is applied (downward in the middle), the portion of the second terminal 50 closer to the wiring connection portion 52 than the bent portion 51 intends to move downward with the bent portion 51 as the base point. When the portion of the second terminal 50 closer to the wiring connection portion 52 intends to move downward with the bent portion 51 as the base point, the limiting surface 63a of the second limiting portion 63 interferes with the flat plate portion 54 of the second terminal 50, thereby limiting the movement. As a result, a force is applied to the wiring connection portion 52 of the second terminal 50 in the axial direction (in the middle). Figure 3 When the force is downward (in the middle), the second restricting portion 63 suppresses the deformation of the second terminal 50.

[0072] Figure 4 It is along Figure 1 A cross-sectional view taken along line IV-IV.

[0073] Reference Figure 4 In this embodiment, the first restricting portion 62 is provided in the housing portion 60 closer to the wiring connection portion 52 than to the bent portion 51. Specifically, the distance D1 between the first restricting portion 62 and the wiring connection portion 52 is shorter than the distance D2 between the first restricting portion 62 and the bent portion 51.

[0074] In addition, the restriction surface 63a of the second restriction portion 63 is arranged on the axial side (at the position of the upper surface 61b of the housing body 61) of the second restriction portion 63. Figure 4 On the other hand, the upper surface 62a of the first restricting portion 62 is arranged to be closer to the other side in the axial direction than the upper surface 61b of the storage portion main body 61 (at Figure 4 (center is the upper side).

[0075] (Manufacturing Method of Stator)

[0076] Below, refer to Figure 5 A method for manufacturing the stator 2 of the motor 1 according to the present embodiment will be described. Figure 5 Schematic diagram for explaining the method for manufacturing the stator 2 of this embodiment, showing the stator 2 as viewed from the axial direction. Figure 5 , only a portion of the plurality of wirings 70 are shown.

[0077] The stator 2 of this embodiment is a stator core 10 ( Figure 1 ), the coils 20, the insulator 30 and other components are arranged in the mold M and are molded by injecting BMC resin into the mold M. That is, the stator 2 is manufactured by insert molding the stator core 10, the coils 20 and the insulator 30 and other components.

[0078] First, the insulator 30 is mounted on the stator core 10 ( Figure 1(as shown), the coil 20 is wound around the teeth 12 of the stator core 10. Next, the first terminal 40 is inserted into the retaining hole 61a of the insulator 30. At this point, the first terminal 40 is electrically connected to the conductive wire of the coil 20. Specifically, the second terminal 50, to which the wiring 70 is connected at the wiring connection portion 52, is then engaged with the first terminal 40, thereby connecting the first terminal 40 and the second terminal 50.

[0079] In the mold M of this embodiment, BMC resin is injected radially inward from two locations separated in the circumferential direction relative to the components of the stator 2 such as the stator core 10, the coil 20, and the insulator 30 (see FIG. Figure 5 In the present embodiment, the flow of the resin inside the mold M has a direction intersecting the axial direction. In addition, the injection direction of the resin is not limited to the direction intersecting the axial direction (in the present embodiment, the radial direction), and may also be a direction along the axial direction.

[0080] According to the motor 1 of this embodiment, the following effects are achieved.

[0081] (1) For example, when a force acts on the second terminal 50 due to the pressure of the resin during insert molding or the tension of the wiring 70 during wiring work, the second terminal 50 may move relative to the first terminal 40 or deform due to this movement. When the second terminal 50 moves and / or deforms relative to the first terminal 40, the contact area between the first terminal 40 and the second terminal 50 may decrease, and the contact resistance between the first terminal 40 and the second terminal 50 may increase. In contrast, in the motor 1 of this embodiment, the first limiting portion 62 limits the circumferential movement of the portion of the second terminal 50 other than the electrical connection portion 53 inserted into the first terminal 40. Therefore, when a circumferential force acts on the second terminal 50, it is possible to suppress the unintended movement and / or deformation of the second terminal 50 relative to the first terminal 40. As a result, it is possible to suppress an increase in the contact resistance between the first terminal 40 and the second terminal 50. For example, when the flow of the resin during insert molding has a direction intersecting the axial direction, as in this embodiment, the resin flowing in the circumferential direction acts on the second terminal 50 in the circumferential direction. The technology of the present invention is particularly effective in such cases.

[0082] (2) In the motor 1 of this embodiment, the first limiting portion 62 limits the portion of the second terminal 50 other than the electrical connection portion 53 inserted into the first terminal 40 from moving toward one side in the axial direction. Therefore, when a force toward one side in the axial direction is applied to the second terminal 50, the second terminal 50 can be prevented from unexpectedly moving relative to the first terminal 40 or deforming due to the movement. Thus, an increase in the contact resistance between the first terminal 40 and the second terminal 50 can be suppressed. For example, when the direction of injection of the resin during insert molding is toward one side in the axial direction (in Figure 3When the direction of the mold is downward, the flow of the resin in the mold is axially oriented. In this case, the resin flowing axially acts on the second terminal 50 in an axially oriented direction. The technology of the present invention is effective in this case.

[0083] (3) In this embodiment, the electrical connection portion 53 of the second terminal 50 is inserted into and fitted into the first terminal 40. Therefore, if a circumferential force acts on the wiring connection portion 52 of the second terminal 50, the portion of the second terminal 50 that is closer to the wiring connection portion 52 than the bent portion 51 tends to move with the bent portion 51 as the base point. Since the first restricting portion 62 is provided in the housing 60 at a position closer to the wiring connection portion 52 than the bent portion 51, the movement of the wiring connection portion 52 or the deformation caused by the movement can be suppressed compared to a case where the first restricting portion 62 is provided in the housing 60 at a position closer to the bent portion 51 than the wiring connection portion 52.

[0084] In the first embodiment described above, an outer rotor type motor was described. However, the technology of the present invention can also be applied to an inner rotor type motor.

[0085] (Second embodiment)

[0086] Figure 6 This is a longitudinal cross-sectional view of a compressor 100 equipped with a motor 101 according to a second embodiment. Motor 101 according to this embodiment differs from motor 1 according to the first embodiment in that it is an inner rotor type motor. On the other hand, motor 101 according to this embodiment is similar to motor 1 according to the first embodiment in that it applies the technology of the present invention. Specifically, motor 101 according to this embodiment also employs the structure for suppressing increases in contact resistance between terminals, as described in the first embodiment.

[0087] The motor 101 of the present embodiment includes an annular stator 102 and a rotor 103 surrounded by the stator 102 .

[0088] Reference Figure 6 The compressor 100 of this embodiment includes: a sealed container 110; a compression mechanism 111 disposed in the sealed container 110; and a motor 101 disposed in the sealed container 110 and driving the compression mechanism 111 via a shaft 112. The compressor 100 can be used in an air conditioner, for example.

[0089] Compressor 100 is a so-called vertical, high-pressure, dome-type rotary compressor. A compression mechanism 111 is disposed at the bottom of a sealed container 110, and a motor 101 is disposed above compression mechanism 111. Compression mechanism 111 is driven by a rotor 103 of motor 101 via a shaft 112. Motor 101 in this application example is an inner rotor type motor, and the technology of the present invention is applied.

[0090] When the compressor 100 is used in an air conditioner, the compression mechanism 111 draws refrigerant gas from the gas-liquid separator 113 through the suction pipe 114. This refrigerant gas is obtained by controlling the condenser, expansion mechanism, and evaporator (not shown) of the air conditioner as an example of a refrigeration system together with the compressor 100.

[0091] The compressor 100 discharges the compressed high-temperature and high-pressure refrigerant gas from the compression mechanism 111, filling the interior of the sealed container 110. The refrigerant gas passes through the gap between the rotor 103 and the stator 102 of the motor 101, and is discharged to the outside from the discharge pipe 115 provided on the upper side of the motor 101.

[0092] In the second embodiment, the same functions and effects as those of the first embodiment are achieved.

[0093] (Third embodiment)

[0094] Figure 7 It is a longitudinal sectional view of a fan motor 200 including a motor 201 according to the third embodiment.

[0095] The motor 201 of this embodiment is an outer rotor type. Specifically, the motor 201 of this embodiment includes an annular stator 202 and an annular rotor 203 disposed so as to surround the stator 202. The stator 202 of this embodiment has the same structure as the stator 2 of the first embodiment described above, and a detailed description thereof will be omitted. Similarly, the rotor 203 has the same structure as the rotor 3 of the first embodiment described above, and a detailed description thereof will be omitted.

[0096] The stator 202 of the motor 201 of this embodiment is covered with a resin mold portion 210. The resin mold portion 210 is formed of BMC resin, which is a thermosetting resin material.

[0097] Furthermore, the fan motor 200 of the present embodiment includes a fan 204 driven by the motor 201 .

[0098] The fan 204 of this embodiment is an axial flow fan. Figure 7 In FIG, the fan 204 is schematically shown, and may be different from the actual size.

[0099] The fan 204 is coupled to a shaft 211. The shaft 211 is supported by a bearing 210a fixed to the resin molded portion 210 so as to be rotatable relative to the resin molded portion 210. The shaft 211 is also fixed to the rotor 203.

[0100] The third embodiment has the same operational effects as those of the first embodiment.

[0101] Although the embodiment has been described above, it should be understood that various changes in form and details can be made without departing from the spirit and scope of the claims.

[0102] For example, in the first to third embodiments described above, the housing portion 60 is provided integrally with the first insulator 31 of the insulator 30 . However, the present invention is not limited thereto and may be provided separately from the insulator 30 .

[0103] In the first to third embodiments described above, the first restricting portion 62 is a protrusion, but the present invention is not limited thereto. The shape, position, and size of the first restricting portion 62 may be appropriately changed according to the shape of the second terminal and the like.

[0104] In the first to third embodiments, the stator core 10 is divided into a plurality of stator core blocks 10P, but the present invention is not limited thereto and the stator core 10 may be formed of a single member.

[0105] The motor of the present invention is not limited to compressor and fan motors, but can also be applied to other devices using motors.
