Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor with a built-in terminal block which is suitable for a capacitor induction motor or the like, and more particularly to an improved assembling means, and a method of manufacturing the same.

[0002]

2. Description of the Related Art FIG. 6 is a longitudinal sectional view showing a capacitor induction motor having a terminal block provided in a motor frame, cut at a main portion. Conventionally, this type of motor 1 includes a stator 3 in a motor frame 2 forming an outer shell as is well known.
Is mounted by press fitting, and a rotating shaft 4
Is provided. And, it is disposed and fixed so as to cover a disk-shaped terminal block 6 which forms a power supply circuit to the motor 1 adjacent to the stator 3 in the axial direction.

The terminal block 6 has a circular opening 6a having the same center as the stator core 3a at the center so that the inside is not hermetically sealed. The opening 6a has an inner diameter of the stator core 3a and further has an inner diameter. The outer diameter of the rotor core 5a is smaller than the outer diameter to secure an area as large as possible on the circumference as the upper surface. For example, two or three capacitors 7 (only one is shown) are provided by sealing by potting, or provided to an external power supply. The terminal connector 8 to be connected is mounted and formed integrally. However, the terminal block 6 is made of, for example, PBT (polybutadiene terephthalate), which is an insulating resin material, and has a conductive member (not shown) forming a circuit pattern embedded therein. It is electrically connected to the capacitor 7, the terminal connector 8, and the like to form a so-called power supply circuit for the motor 1.

[0004]

As described above, in the conventional configuration, the area of the upper surface of the terminal block 6 is made as large as possible so that the capacitor 7 and the terminal connector 8 can be mounted. When the terminal block 6 is arranged and fixed on the stator 3 and the stator coil 3b and the circuit pattern inside the terminal block 6 are soldered, since the central opening 6a is small in diameter, the stator When the terminal 3 and the terminal block 6 are assembled in the motor frame 2 first, the rotor 5 cannot be mounted thereafter. Therefore, in such a configuration, the rotor 5 having the rotating shaft 4 is assembled first, and then the stator 3 and the terminal block 6 are assembled. Alternatively, although the assembling work is troublesome, it is also possible to separately arrange and fix the terminal blocks 6 by separately soldering after mounting the stator 3 and the rotor 5.

However, in any case, after disassembly with the rotor 5 is required after the assembly and manufacture of the motor 1 for quality inspection and internal inspection, etc., the stator 3 and the terminal block 6 must be removed integrally. Take out the rotor 5 or
In addition, most of the disassembly is required, such as removing the soldered terminal block 6 and then removing the rotor 5 and the stator 3, which is troublesome, and the repair work (assembly) is also troublesome and not easy. .

When the rotor 5 is pre-attached as described above, the rotating shaft 4 and the bearing 9 may be damaged by the stator 3 which is press-fitted later, and the pre-installed rotor 5 may be temporarily held. It is not an efficient assembly work because care must be taken to ensure it.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a motor with a built-in terminal block, which can load a rotor even after a stator or a terminal block is installed, and which can be efficiently disassembled and assembled. It is to provide a manufacturing method thereof.

[0008]

In order to achieve the above object, a motor with a built-in terminal block according to the present invention comprises: a stator having a stator frame in which a stator coil is wound into a motor frame; A rotor having a rotor core provided on the circumferential side and having a rotating shaft, and a conductive member forming a circuit pattern connected to the stator coil embedded therein, and a terminal connector connected to a capacitor or an external power supply mounted thereon. In a device provided with a disk-shaped terminal block, the terminal block is provided with an opening having a diameter larger than that of the rotor core at a central portion, and is arranged adjacent to the stator in the axial direction. (The invention of claim 1).

According to such a configuration, particularly in the disassembling and assembling operations involving the attachment and detachment of the rotor, there is no need for a troublesome operation of removing the stator or the terminal block incorporated by the fixing means such as press-fitting. It can be easily inserted and removed from the opening of the table, and thus can be disassembled and assembled efficiently.

According to the first aspect of the present invention, the opening of the terminal block has a circular shape and is formed at a center position eccentric to the center of the outer diameter of the terminal block. Invention).

According to this configuration, substantially the same operation and effect as those of the first aspect can be expected, and in addition, the capacitor and the terminal connector can be appropriately utilized by making use of the particularly wide peripheral area of the terminal block due to the eccentricity of the opening. This has the advantage that relatively large components and devices such as the above can be effectively arranged.

Further, according to the second aspect, the center position of the opening of the terminal block is shifted in a direction opposite to the terminal connector, and the capacitor provided in connection with the circuit pattern of the terminal block is connected to the terminal connector. (See the invention of claim 3).

According to such a configuration, the terminal connector can be provided on a wide peripheral area of the terminal block due to the eccentricity, so that the degree of freedom in design is increased, and the connector configuration is sufficient in function and strength. In addition, the peripheral area orthogonal to the peripheral area does not largely change in the area width or the like in the intermediate area. Therefore, it is convenient to secure a required area and is suitable for disposing a relatively large capacitor.

According to another aspect of the present invention, there is provided a method of manufacturing a motor with a built-in terminal block, wherein a stator having a stator coil wound thereon is press-fitted into a motor frame; A rotor having a rotor core disposed on the side and having a rotating shaft, and a disk having a conductive member constituting a circuit pattern connected to the stator coil embedded therein and having a terminal connector connected to a capacitor or an external power supply mounted thereon Terminal block, the terminal block having an opening larger in diameter at the center than the rotor core and disposed adjacent to the stator in the axial direction. The stator and the terminal block are mounted on a motor frame. After that, the rotor is loaded and assembled from the opening of the terminal block (the invention of claim 4).

According to such a manufacturing method, in the conventional configuration, the stator or the like is press-fitted in a state where the rotor is inserted and held first, so that the rotor and the bearing may be damaged at that time. Since the rotor is assembled after the stator and the terminal block are mounted, the rotor does not need to be maintained in an unreasonable holding state and no complicated work is required. Therefore, there is no danger of damaging the rotor during assembly, and the motor can be manufactured efficiently.

The terminal block 28 has an outer diameter and a circular opening 29 formed in the center, and has a concentric shape with the center position A, and a circuit pattern for supplying power to the stator coil 19 (not shown). A conductive member is inserted and formed integrally with PBT which is an insulating resin material. In addition, the opening 29 is formed in the rotor core 21 (FIG. 3) inserted in the stator core 16.

The terminal block 28 is provided with through-hole-shaped connection portions 31 at, for example, four places where coil terminals (not shown) derived from the main coil and the auxiliary coil constituting the stator coil 19 are inserted. , 32, 33, and 34 are provided so as to partially expose the conductive members, and are connected to the internal circuit pattern by inserting the coil terminals and soldering. In addition, a terminal connector 35 electrically connected to such a circuit pattern and connected to an external power supply is integrally protruded, and has a box shape opened to the side as shown in FIG. It has a configuration in which four terminals 35a, 35b, 35c, and 35d protrude inside, and is formed so as to protrude upward as a whole shape, and does not protrude at least to the inside of the opening 29 side.

Further, for example, two capacitors 36 and 37 (shown by broken lines in FIG. 3) connected to the circuit pattern are potted and sealed with potting resin portions 38 and 38 which are also capacitor storage portions. ing. Although these capacitors 36 and 37 are set to predetermined capacitor capacities in accordance with the rated capacity of the motor 11, in the case of this embodiment, two capacitors 36 and 37 are used in order to reduce the size per one. Are connected in parallel. Therefore, as in the present embodiment, this type of capacitors 36, 3
The number 7 is not limited to two and may be three. In addition, thermal fuse connecting portions 38 and 39 for mounting thermal fuses (not shown) are formed on the extended ends of the internal conductive members on the terminal block 28, and are electrically connected via the thermal fuses. A part of the circuit pattern is formed.

As described above, the terminal block 28 has an opening 29 having a diameter larger than that of the rotor core 21 at the center, and a conductive member (not shown) for forming a circuit pattern therein. By effectively utilizing the surface area on the periphery of the terminal block 28, a terminal connector 35 provided integrally, capacitors 36 and 37 sealed by potting, a thermal fuse (not shown), and the like can be mounted.

However, such a terminal block 28 is disposed and fixed adjacent to the stator 15 in the axial direction as shown in FIG.
In this embodiment, as the fixing means, on the stator 15 side, three places (only one place is shown) on the periphery of the synthetic resin upper cover 17 project upward in a bifurcated manner so as to be elastically deformable. The engaging claw 40 is provided, and a rectangular engaging cylinder 41 whose lower surface is opened protrudes from the back surface of the terminal block 28 in a positional relationship facing the engaging claw 40. .

Therefore, the engagement claw 4 is provided in the engagement cylinder 41.
By inserting 0, the movement in the lateral direction is prevented, and the terminal block 28 is elastically engaged with the claw so that the terminal block 28 is retained in a retaining state. Attached to. Although a specific description is omitted, it is easy to insert a coil terminal from the stator coil 19 into the connection portions 31 to 34 of the terminal block 28 by attaching and fixing the terminal block 28 to the stator 15. Consideration has also been given to positioning.

FIG. 1 is a longitudinal sectional view for explaining the assembling procedure in the main part of the motor 11 described above. First, the terminal block 28 is sealed by potting as well as the terminal connector 35 provided integrally. Capacitor 3
6, 37, and a temperature fuse (not shown) are mounted and fixed to the stator 15 by elastic engagement between the engaging claw portion 40 and the engaging cylindrical portion 41. At this time, a coil terminal (not shown) of the stator coil 19 is connected to the connection portion 31.
To 34 (see FIG. 3), and are electrically connected to a power supply circuit pattern by soldering.

The stator 15 having the terminal block 28 adjacently fixed thereon as described above is mounted on the lower frame 14 of the motor frame 12.
Press in and fix. Thus, as described above, the stator core 16 and the disk-shaped terminal block 28 are substantially concentrically arranged, and the stator core 16
In this embodiment, a hollow portion is formed by connecting the inner peripheral portion of the core 16 and the opening 29 having a diameter larger than the inner diameter of the core 16 in this embodiment.

Next, the rotor 20 is loaded into the hollow portion. At this time, since the diameter of the rotor core 21 is smaller than that of the opening 29, the rotor core 21 can be inserted without any trouble in the hanging direction shown in the figure. In this case, a rotary shaft 23 is first press-fitted and fixed to the center of the rotor core 21 on the rotor 20. The rotary shaft 23 has bearings 24,
Needless to say, the outer diameter of the bearing 24 is smaller than that of the rotor core 21.

Accordingly, the lower bearing 24 is housed in the lower bracket 26 via the thrust receiving member 27 and is held at this position. And the upper frame 13
2 (see FIG. 2) is passed through the rotating shaft 23, and the upper bearing 24 is housed in the upper bracket 25 and put on the lower frame 14. In this case, the cylindrical upper frame 13
Are formed on the lower frame 14 by fitting the upper part of the stator core 16, and are formed as the motor frame 12 by burring caulking 13 at a plurality of locations on their outer peripheral edges and being joined together. After completion, the capacitor induction motor 11 including the terminal block 28 is completed.

As described above, according to the present embodiment, the capacitor 3 is used to form a power supply circuit for the stator coil 19.
6 and 37, a disk-shaped terminal block 28 having a terminal connector 35, etc., which is disposed adjacent to the upper part of the stator 15 in the axial direction. The configuration is such that an opening 29 to be large is provided. After the stator 15 and the terminal block 28 are mounted into the lower frame 14 of the motor frame 12 by press-fitting or the like according to the above configuration, the rotating shaft 23 is provided on the inner peripheral side of the stator core 16 from the opening 29 of the terminal block 28. The motor 11 is assembled by loading the rotor 20 thus assembled.

This makes it easy to disassemble and assemble. For example, when checking the balance of the bearing 24 and the rotor 20 in order to check factors such as operation noise (noise) in the quality inspection of the motor 11, for example. , Upper frame 13
By removing the rotor, the rotor 20 and the like can be easily taken out through the opening 29 of the terminal block 28. Since the terminal block and the stator are removed as in the above-described conventional configuration, there is no need for a troublesome work of removing the soldering and press-fitting portions. Of course, in the case of repairing (assembling) from this disassembled state, the rotor 20 is installed in the reverse procedure to cover the upper frame 13 so that disassembly and assembly can be easily performed. It is also possible to efficiently carry out quality inspections and the like involving work.

In the conventional configuration, the stator is press-fitted while the rotor is held, and the terminal block is mounted. Therefore, the rotor, the rotating shaft, the bearings, and the like may be damaged. According to the embodiment, since the rotor 20 is assembled after the stator 15 and the terminal block 28 are mounted, it is not necessary to maintain the rotor 20 and the rotating shaft 23 in an unreasonable holding state. The motor 11 can be assembled and manufactured efficiently.

(Second Embodiment) Next, FIGS. 4 and 5 show a second embodiment of the present invention. Only the different parts will be described below. FIG. 4 is a diagram corresponding to FIG.
FIG. 5 is a diagram corresponding to FIG. 1. First, the configuration of this embodiment will be described with reference to FIG. The terminal block 42 described here is the first
In the embodiment, an opening 43 and two capacitors 4 are provided.
The differences are only in the arrangements of 4, 45, and the others are substantially in common.

That is, first, the center position A where the center line indicated by the dashed line in the figure intersects is the position of the originally disk-shaped terminal block 42 (outer diameter), the stator core 16 (the inner diameter is shown in dashed line in the figure), etc. In contrast to the original center, the center line shown by the broken line in the figure is shifted by the dimension α only in the direction opposite to the position where the terminal connector 46 is provided, and based on the eccentric center position B, the circular opening 43 is formed. The other dimensions such as the inner diameter are the same as those of the first embodiment.

On the other hand, the two capacitors 44 and 45 indicated by broken lines in the figure are located on the periphery of the center where the terminal connector 46 is provided and are shifted by about 90 degrees to the left and right with respect to the center, as indicated by the broken lines. These capacitors are provided at positions corresponding to the lines, respectively, and are substantially the same as those of the first embodiment except for this arrangement. These capacitors 44, 45 are potting resin portions 47, 47 which are also capacitor storage portions. Sealed.

Next, the procedure for assembling the capacitor induction motor 48 having the terminal block 42 will be described with reference to FIG. 5. In this embodiment, similarly to the first embodiment, an opening 43 having a diameter larger than that of the stator core 16 is provided. After the stator 15 to which the terminal block 42 was attached and fixed was press-fitted into the lower frame 14 constituting the motor frame 12, the rotating shaft 23 and the bearing 24 were provided through the opening 43. It is possible to load and incorporate the rotor 20.

However, in this embodiment, as disclosed in FIG. 4, the center position B of the opening 43 is set to the terminal connector 46.
The eccentric configuration is shifted by the dimension α in the direction opposite to the position. Therefore, the center position A shown by the two-dot chain line in FIG.
The inner diameter of the stator core 16 and the opening 43 due to the center position B greatly differ from each other as seen in a plan view, which means that the deviation of the axial center from the stator 15 is also apparent in the longitudinal sectional view of FIG. It is.

That is, the inner diameter portion of the opening 43 on the terminal connector 46 side slightly protrudes inward as shown in FIG. 5 with respect to the inner diameter of the stator core 16, and conversely, the inner diameter portion on the opposite side is outside. It is incorporated in an eccentric state so as to form a retreated form. For this reason, since the opening 43 and the rotor 20 to be loaded are arranged so that the center positions, which are the axial centers thereof, are different from each other, as shown in the drawing, the rotor core 2
1 passes through the opening 43 while the rotor 20 and the rotating shaft 2
3 is inserted into the terminal connector 46 on the side opposite to the terminal connector 46 in a slightly inclined state so as to avoid contact with the upper portion of the stator 15.

The rotor core 21 is connected to the opening 4
After passing through the motor 3, the motor is inserted straight down in the same manner as in the first embodiment, and then the lower bearing 24 is loaded into the lower bracket 26, and the upper frame 13 (not shown) is attached. 48 are assembled and manufactured. Even if the rotor 20 is tilted and loaded, depending on the size (corresponding to α) of the center line being shifted as shown by the broken line in the figure.
If there is a possibility that the rotor core 21 may come into contact with the upper portion of the upper cover 17, a part of the upper cover 17 may be cut out to provide the cutout portion 17 a.

According to the above-described embodiment, the center of the opening 43 provided at the center of the terminal block 42 is eccentrically shifted by the dimension α. As a result, the upper surface of the disk-shaped terminal block 42 has a configuration in which a wide peripheral area continuously changes from a narrow peripheral area,
Therefore, it is convenient to arrange components or devices having a large occupied area in a wide peripheral area. Incidentally, in the illustrated embodiment, the terminal connector 46 is provided integrally, but in this case, the degree of design freedom is increased such that the terminal connector 46 can be further enlarged. Between the other terminal connector (not shown) which is inserted and connected as a pair, it is possible to adopt a connector with a lock function which is not easily disconnected simultaneously with the electrical connection. Is the terminal connector 46
May be attached separately.

Further, in the present embodiment, the capacitors 44 and 45 are provided at respective positions on the circumference developed approximately 90 degrees left and right about the terminal connector 46, respectively. The developed position shifted by 90 degrees is located in the middle where the above-mentioned wide peripheral area and narrow peripheral area change, and is an area where the area width or the like is small, in other words, the amount of eccentricity (corresponding to α).
On the other hand, it is convenient to always secure the required area without being particularly affected by a reduction in area, and therefore, two capacitors 44, which are relatively large components, in particular, are particularly large.
45 can be effectively arranged individually.

In addition, the opening 43 at the center of the terminal block 42 is larger in diameter than the rotor core 21, and the rotor 20 is loaded from the opening 43 after the stator 15 and the terminal block 42 are mounted. It goes without saying that the effect of the manufacturing method of assembling and the like, that is, easy and efficient disassembly and assembly can be expected as in the first embodiment.

The present invention is not limited to the embodiment described above and shown in the drawings. For example, the number and form of the capacitors and terminal connectors mounted on the terminal block can be specifically and variously changed. The present invention is not limited to the capacitor induction motor described in the above embodiments, and can be variously modified and implemented without departing from the gist of the present invention.

Further, according to the present invention, there is provided a method for manufacturing a motor with a built-in terminal block, wherein the stator and the terminal block are mounted in the motor frame by press fitting or the like, and then the rotor is loaded into the terminal block through the opening and incorporated therein.

In this manner, the disassembly and assembly can be easily performed.
