Description

Technical Field

[0001] This invention relates to the field of motor technology, specifically to a motor wiring device, a motor, and a compressor. Background Technology

[0002] Wiring devices have a wide range of applications, used during assembly to connect multiple important components. For example, inside a motor, the wires leading from the motor need to be connected to external equipment, requiring a wiring device to secure and connect the wires. In existing technology, the connection between the wiring device and the terminal block inside the compressor often requires manual alignment and connection. This step wastes a lot of time, and for manual connection, the compressor casing cannot be fully sealed, posing a challenge to the compressor's sealing performance.

[0003] Because existing compressors have technical problems such as the motor lead wire assembly occupying compressor space, resulting in a heavy compressor, this invention studies and designs a motor fixing device, a motor, and a compressor. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the motor lead wire assembly of the compressor in the prior art requires space in the compressor, resulting in a heavy compressor, thereby providing a motor fixing device, a motor and a compressor.

[0005] To address the above problems, the present invention provides a motor wiring fixing device, comprising:

[0006] The device comprises a wire fixing body, a snap-fit ​​part, and a limiting part. The snap-fit ​​part is connected to the wire fixing body and faces the insulating frame of the motor. The snap-fit ​​part can snap onto the insulating frame. The limiting part is connected to the wire fixing body and faces the stator core of the motor. The limiting part can cooperate with the stator core to limit movement. The wire fixing body is also provided with a terminal block channel and a terminal channel to fix and guide the lead wires of the motor.

[0007] In some implementations...

[0008] The wire fixing body includes a first side and a second side facing away from each other. The first side is opposite to and fits against the insulating frame. The snap-fit ​​part is disposed on the first side and has an opening groove facing both the axial direction and the circumferential direction of the motor. The snap-fit ​​part can be snapped onto the insulating frame along the axial direction and the circumferential direction through the opening groove.

[0009] In some implementations...

[0010] The radial direction of the fixed wire body is the same as that of the motor. The snap-fit ​​part includes a connecting part and a slot part. The connecting part is connected to the first surface and protrudes radially inward towards the motor. The slot part includes an axially outer part and a radially inner part. The axial length of the axially outer part is less than the axial length of the connecting part and is connected to one circumferential side of the axially outer section of the connecting part. The radial length of the radially inner part is less than the radial length of the connecting part and is connected to one circumferential side of the radially inner section of the connecting part. The axially outer part, the radially inner part, the connecting part, and the first surface together form an opening slot that opens axially and circumferentially.

[0011] In some implementations...

[0012] The depth of the opening groove along the motor axis is a1, where a1 is 5-8mm, and the ratio of the area occupied by the slot portion on the first surface to the area of ​​the first surface is 1 / 5 to 1 / 3.

[0013] In some implementations...

[0014] The terminal block channel is opened on the second surface;

[0015] The first surface is an arc surface that matches the insulating frame, and the second surface is a plane.

[0016] In some implementations...

[0017] The axial direction of the wire fixing body is the same as that of the motor. The limiting part is disposed at one end of the axial direction of the wire fixing body. The snap-fit ​​part is disposed on the first surface and connected to the other end of the axial direction of the wire fixing body. The limiting part includes a protrusion facing the stator core. The stator core is provided with a groove that cooperates with the protrusion, so that the protrusion can be snapped in the groove to provide circumferential limiting for the motor wire fixing device.

[0018] In some implementations...

[0019] The main body of the fixed wire is provided with a third surface at the position where the first surface and the limiting part meet. The third surface is closer to the second surface than the first surface. The third surface can fit against the outer peripheral surface of the stator core to form a first stepped surface at the junction of the third surface and the first surface. The first stepped surface is engaged with the insulating frame.

[0020] In some implementations...

[0021] The first step surface is the end face of one axial end of the first surface, and its width along the radial direction of the motor is b7, where b7 is 3-4mm; the axial end face of the third surface away from the first step surface is the second step surface, and the second step surface is engaged with the shaft end face of the stator core; the limiting part is provided on the second step surface, and the width along the radial direction of the second step surface where the limiting part is not provided is b8, where b8 is 3-4mm, the limiting part is provided to protrude axially from the second step surface, and the axial end face of the limiting part away from the second step surface is the third step surface, and the width along the radial direction of the third step surface is b9, where b9 is 5-6mm.

[0022] In some implementations...

[0023] The terminal block channel includes three channels, all of which are circular channels. The centers of the three circular channels are located on the same circle, and the three circles are spaced 120° apart. The terminal block channel has a chamfer.

[0024] In some implementations...

[0025] The terminal channel is provided on one circumferential side of the fixed wire body, and a terminal can be disposed in the terminal channel. The terminal channel extends from one circumferential side of the fixed wire body to the other circumferential side, and the terminal channel communicates with the terminal block channel inside the fixed wire body.

[0026] In some implementations...

[0027] The terminal channel includes a first channel and a second channel that are connected in its extending direction. The width of the second channel is greater than the width of the first channel in the axial direction of the motor, and the height of the second channel is less than the height of the first channel in the radial direction of the motor.

[0028] In some implementations...

[0029] Inside the terminal channel, the first channel and the second channel are connected, and a first step in the direction of the height and a second step in the direction of the width are formed at the connection point. The height b6 of the first step is greater than 1 / 2 of the height of the terminal, and the width b5 of the second step is 0.5 to 0.8 mm.

[0030] In some implementations...

[0031] The terminal channel includes three terminals, which are arranged sequentially at intervals along the axial direction of the motor, and each terminal channel is connected to a corresponding terminal post channel. Between two adjacent terminal channels, the first channel in one terminal channel is connected to one circumferential end face of the wire fixing body, and the second channel is connected to the other circumferential end face of the wire fixing body; the second channel in the other terminal channel is connected to one circumferential end face of the wire fixing body, and the first channel is connected to the other circumferential end face of the wire fixing body.

[0032] The present invention also provides an electric motor, which includes the aforementioned motor wiring device.

[0033] The present invention also provides a compressor that includes the aforementioned motor.

[0034] The motor wiring device, motor, and compressor provided by this invention have the following beneficial effects:

[0035] 1. This invention, by configuring the motor wiring device as including a wiring body, a snap-fit ​​part, and a limiting part, enables the motor wiring device to be snapped onto the insulating frame via the snap-fit ​​part, and to form a limiting connection with the stator core of the motor via the limiting part. This fixes the motor wiring device to the insulating frame and the stator core, effectively positioning and limiting it. This effectively eliminates the compressor space required for the lead wire assembly, reducing compressor weight and solving the problem of existing compressors where the motor lead wire assembly occupies compressor space, resulting in a heavy compressor. Furthermore, by connecting the wiring device to the insulating frame and stator core and installing it into the compressor along with the motor, this invention avoids contact with the external environment, reducing the risk of short circuits caused by external impurities entering the wiring device. It also simplifies the terminal assembly process, offering advantages of simple assembly and high efficiency.

[0036] 2. Preferably, the present invention configures the snap-fit ​​portion as having an opening groove facing both the axial and circumferential directions of the motor. This opening groove allows the snap-fit ​​portion to be snapped onto the insulating frame along both the axial and circumferential directions, effectively positioning and limiting the motor wire fixing device in the axial and radial directions. The structure is simple, the installation is secure, and disassembly is convenient. Further preferably, the present invention configures the limiting portion of the wire fixing device as a protruding structure facing the stator core, with a corresponding groove on the stator core that fits in a concave-convex manner. This allows the protruding limiting portion to snap into the groove of the stator core, effectively limiting the wire fixing device in the circumferential direction and preventing it from sliding along the circumferential direction, further improving the positioning and fixing effect of the wire fixing device.

[0037] 3. The present invention further preferably uses a first stepped surface of the wire fixing device in the axial direction to form an axial engagement and limit with the insulating frame, thereby further improving the positioning and limiting effect with the insulating frame; the second stepped surface can engage with the shaft end face of the stator core, thereby further improving the positioning and limiting effect of the wire fixing device; the present invention further uses a terminal channel structure with first and second channels of different widths and heights to achieve the effect of limiting the terminal and avoid poor contact between the terminal and the terminal block.

Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0053] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0054] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.

[0057] like Figure 1-11 As shown, the present invention provides a motor wiring fixing device, which includes:

[0058] The device comprises a wire fixing body 1, a snap-fit ​​part 2, and a limiting part 3. The snap-fit ​​part 2 is connected to the wire fixing body 1 and faces the insulating frame 4 of the motor. The snap-fit ​​part 2 can snap onto the insulating frame 4. The limiting part 3 is connected to the wire fixing body 1 and faces the stator core 5 of the motor. The limiting part 3 can cooperate with the stator core 5 to limit the movement. The wire fixing body 1 is also provided with a terminal block channel 6 and a terminal channel 7 to fix and guide the lead wires of the motor.

[0059] This invention, by configuring the motor wiring device as including a wiring body, a snap-fit ​​part, and a limiting part, enables the motor wiring device to be snapped onto the insulating frame via the snap-fit ​​part, and to form a limiting connection with the stator core of the motor via the limiting part. This fixes the motor wiring device to the insulating frame and stator core, effectively positioning and limiting it. This effectively eliminates the compressor space required for the lead wire assembly, reducing compressor weight and solving the problem of existing compressors where the motor lead wire assembly occupies compressor space, resulting in a heavy compressor. Furthermore, by connecting the wiring device to the insulating frame and stator core and installing it into the compressor along with the motor, this invention avoids contact with the external environment, reducing the risk of short circuits caused by external impurities entering the wiring device. It also simplifies the terminal assembly process, offering advantages of simple assembly and high efficiency.

[0060] In some implementations...

[0061] The wire fixing body 1 includes a first surface 11 and a second surface 12 facing away from each other. The first surface 11 is opposite to and fits against the insulating frame 4. The snap-fit ​​part 2 is disposed on the first surface 11 and has an opening groove 20 that faces both the axial direction and the circumferential direction of the motor. The snap-fit ​​part 2 can be snapped onto the insulating frame 4 along the axial direction and the circumferential direction through the opening groove 20.

[0062] The present invention preferably sets the snap-fit ​​part to have an opening groove facing both the axial direction and the circumferential direction of the motor. The snap-fit ​​part can be snapped onto the insulating frame along the axial and circumferential directions through the opening groove, thereby effectively positioning and limiting the motor fixing device in the axial and radial directions. The structure is simple, the installation is firm, and the disassembly and assembly are convenient.

[0063] In some implementations...

[0064] The radial direction of the fixed wire body 1 is the same as that of the motor. The snap-fit ​​part 2 includes a connecting part 21 and a slot part 22. The connecting part 21 is connected to the first surface 11 and protrudes radially inward toward the motor. The slot part 22 includes an axially outer part 23 and a radially inner part 24. The axial length of the axially outer part 23 is less than the axial length of the connecting part 21 and is connected to one circumferential side of the axially outer segment of the connecting part 21. The radial length of the radially inner part 24 is less than the radial length of the connecting part 21 and is connected to one circumferential side of the radially inner segment of the connecting part 21. The axially outer part 23, the radially inner part 24, the connecting part 21 and the first surface 11 together form an opening slot 20 that opens axially and circumferentially.

[0065] This is a preferred structural form of the snap-fit ​​part of the present invention, which includes a connecting part and a snap-fit ​​part connected to the first surface. The snap-fit ​​part preferably includes an axially outer part and a radially inner part. The axially outer part is connected to the connecting part to form a groove structure that axially limits the wire fixing device relative to the insulating frame, while the radially inner part is connected to the connecting part to form a groove structure that radially limits the wire fixing device relative to the insulating frame. This forms an open groove structure that can limit the wire fixing device both axially and radially, thereby improving the snap-fit ​​stability of the wire fixing device.

[0066] In some implementations...

[0067] The depth of the opening slot 20 along the motor axis is a1, where a1 is 5-8mm. The ratio of the area occupied by the slot portion 22 on the first surface 11 to the area of ​​the first surface 11 is 1 / 5 to 1 / 3.

[0068] like Figure 3 As shown, the buckle is located at the top of the wire fixing device and is shaped like an arc-shaped groove (open groove) with the same curvature as the back of the wire fixing device. The depth a1 is 5-8mm, and the area of ​​the arc-shaped groove occupies 1 / 5 to 1 / 3 (preferably 1 / 4) of the first surface of the wire fixing device. The left side of the arc-shaped groove is open and the right side is closed. The right side hangs on the insulating frame, thus axially limiting the wire fixing device. The depth and area of ​​the arc-shaped groove are designed to ensure that it can firmly hang on the insulating frame and will not move downward. After the wire fixing device is installed in place, the motor enameled wire will be connected to the terminal and enter from the direction of the first channel of the terminal. The enameled wire is bound by the binding rope, so that the wire fixing device will not move upward, thus achieving the effect of axially limiting the wire fixing device.

[0069] In some implementations...

[0070] The terminal channel 6 is provided on the second surface 12;

[0071] The first surface 11 is an arc surface that matches the insulating frame 4, and the second surface 12 is a plane.

[0072] The present invention preferably places the terminal block channel on the second surface of the wire-fixing body. This second surface is preferably flat, which can further reduce the space occupied by the wire-fixing device and reduce the weight of the compressor. The terminal block channel can accommodate the terminal block, thereby forming a wire connection with the terminal in the terminal channel, ensuring effective wiring to the motor. The first surface is preferably curved, which can form an effective fit with the outer peripheral surface of the insulating frame, further reducing the space occupied by the wire-fixing device and reducing the weight of the compressor. The front of the wire-fixing device of the present invention is a smooth flat surface (i.e., the second surface) and is provided with a terminal block channel, which further eliminates the compressor space required for the lead wire assembly and reduces the weight of the compressor.

[0073] In some implementations...

[0074] The axial direction of the wire fixing body 1 is the same as that of the motor. The limiting part 3 is disposed at one end of the axial direction of the wire fixing body 1. The snap-fit ​​part 2 is disposed on the first surface 11 and connected to the other end of the axial direction of the wire fixing body 1. The limiting part 3 includes a protrusion 8 facing the stator core 5. The stator core 5 is provided with a groove that cooperates with the protrusion 8, so that the protrusion 8 can be snapped in the groove to provide circumferential limiting for the motor wire fixing device.

[0075] In a further preferred embodiment of the present invention, the limiting part of the wire fixing device is configured as a protrusion facing the stator core, and the stator core is provided with a groove that is opposite to and fits the protrusion, so that the protrusion limiting part can be locked in the groove of the stator core, effectively limiting the wire fixing device in the circumferential direction and preventing it from sliding in the circumferential direction, thereby further improving the positioning and fixing effect of the wire fixing device.

[0076] The limiting post of the present invention preferably includes a protrusion, which is provided at the bottom end of the wire fixing device and connects to the three steps of the bottom surface. Its shape is preferably a semi-cylinder. A groove with the same curvature is provided at the corresponding position of the stator core, which cooperates with the groove to radially limit the wire fixing device.

[0077] In some implementations...

[0078] A third surface 13 is also provided on the main body 1 of the wire fixing body at the position where the first surface 11 and the limiting part 3 meet. The third surface 13 is closer to the second surface 12 relative to the first surface 11. The third surface 13 can fit with the outer peripheral surface of the stator core 5 to form a first stepped surface 14 at the junction of the third surface 13 and the first surface 11. The first stepped surface 14 is engaged with the insulating frame 4.

[0079] The present invention further preferably uses the first stepped surface of the wire fixing device in the axial direction to form an axial engagement and limit with the insulating frame, which further improves the positioning and limiting effect with the insulating frame. The third surface can be fitted to the outer peripheral surface of the stator core, which further reduces the space occupied by the wire fixing device and reduces the weight of the compressor.

[0080] In some implementations...

[0081] The first stepped surface 14 is the end face of one axial end of the first surface 11, and its width along the radial direction of the motor is b7, where b7 is 3-4 mm; the axial end face of the third surface 13 away from the first stepped surface 14 is the second stepped surface 15, and the second stepped surface 15 is engaged with the shaft end face of the stator core 5; the limiting part 3 is provided on the second stepped surface 15, and the width of the portion of the second stepped surface 15 without the limiting part 3 along the radial direction of the motor is b8, where b8 is 3-4 mm; the limiting part 3 is provided to protrude axially from the second stepped surface 15; the axial end face of the limiting part 3 away from the second stepped surface 15 is the third stepped surface 16, and the width of the third stepped surface 16 along the radial direction of the motor is b9, where b9 is 5-6 mm.

[0082] The present invention preferably uses a second stepped surface that can engage with the shaft end face of the stator core, further improving the positioning and limiting effect of the wire fixing device. The width b7 of the first step surface of the three-stage step is preferably 3-4 mm, which mates with the outer edge of the insulating frame; the width b8 of the second step surface is preferably 3-4 mm, which mates with the top surface of the stator core; and the width b9 of the third step surface is preferably 5-6 mm, which mates with the outer edge of the stator core. The length of the three steps is consistent with the width of the wire fixing device. The three-stage step design facilitates better engagement of the wire fixing device with the stator core and insulating frame, achieving precise positioning and facilitating subsequent connection of the terminals.

[0083] In some implementations...

[0084] The terminal channel 6 includes three channels, all of which are circular channels. The centers of the three circular channels are located on the same circle, and the three circles are spaced 120° apart. The terminal channel 6 has chamfers.

[0085] The present invention, through the above-mentioned terminal block channel arrangement, can match the terminal blocks and facilitate wiring; that is, the interface at the end (connecting the power supply and the motor), and the arrangement of the terminal block channel holes is also related to the position of the lead wires. According to the channel hole arrangement order of the present invention, two lead wires are distributed on the left and one lead wire is distributed on the right, which plays a role in fixing and limiting the wire fixing device; the terminal block channel holes are chamfered to preliminarily position the terminal blocks and make it easier to connect.

[0086] In some implementations...

[0087] The terminal channel 7 is provided on one circumferential side of the wire fixing body 1. A terminal can be installed in the terminal channel 7. The terminal channel 7 extends from one circumferential side of the wire fixing body 1 to the other circumferential side. The terminal channel 7 communicates with the terminal block channel 6 inside the wire fixing body 1.

[0088] This invention utilizes a terminal channel that extends from one circumferential side of the main body to the other circumferential side. This channel can accommodate terminals and connect with the terminal block channel, enabling wiring between the terminal block and the terminal block. This ensures effective wiring to the motor. Furthermore, the wiring is done from the inside, eliminating the need for complex external winding. This further reduces the volume occupied by messy winding, further reduces the space required for the compressor, and further reduces the weight of the compressor.

[0089] In some implementations...

[0090] The terminal channel 7 includes a first channel 71 and a second channel 72 connected in its extending direction. The width of the second channel 72 in the axial direction of the motor is greater than the width of the first channel 71, and the height of the second channel 72 in the radial direction of the motor is less than the height of the first channel 71.

[0091] The present invention further achieves the effect of limiting the terminal by setting the terminal channel into a structure with first and second channels of different widths and heights, thereby avoiding poor contact between the terminal and the terminal block.

[0092] In some implementations...

[0093] Inside the terminal channel 7, the first channel 71 and the second channel 72 are connected, and a first step 9 in the direction of the height and a second step 10 in the direction of the width are formed at the connection. The height b6 of the first step 9 is greater than 1 / 2 of the height of the terminal, and the width b5 of the second step 10 is 0.5 to 0.8 mm.

[0094] like Figure 6 and 11 As shown, the terminal channel of the present invention is divided into a first channel 71 and a second channel 72. The width b1 of the second channel is greater than the width b2 of the first channel, preferably 1-1.6 mm greater, to create a width difference with the first channel. This width difference is used to hold the terminal fins in place and prevent the terminal from coming out. The height b3 of the second channel is less than the height b4 of the first channel. The first and second channels intersect to form a first step 9 and a second step 10. The width of the second step is b5, and the height of the first step is b6. The height b6 is greater than half the height of the terminal. The width of b5 is required to be 0.5-0.8 mm, to create a height difference with the first channel. This height difference is used to block the front end of the terminal and prevent the terminal from coming out. The terminal enters from the first channel and stops at the first step. The terminal head fins are held in place by the second step, so that the terminal head stops at the junction of the first and second channels. The terminal post is assembled with the terminal post through the terminal post channel.

[0095] In some implementations...

[0096] The terminal channel 7 includes three terminals, which are arranged sequentially at intervals along the axial direction of the motor, and each terminal channel 7 is connected to a corresponding terminal post channel 6. Between two adjacent terminal channels 7, the first channel 71 of one terminal channel 7 is connected to one circumferential end face of the wire fixing body 1, and the second channel 72 is connected to the other circumferential end face of the wire fixing body 1; the second channel 72 of the other terminal channel 7 is connected to one circumferential end face of the wire fixing body 1, and the first channel 71 is connected to the other circumferential end face of the wire fixing body 1.

[0097] This invention, through the different structural arrangements of the adjacent terminal channels, ensures that the terminal channels arranged on the side of the wire fixing device are in a crisscross pattern. Specifically, one terminal channel of the wire fixing device, from left to right, is arranged as channel one, channel two, channel one, while the adjacent terminal channel is arranged as channel two, channel one, channel two. This crisscross arrangement of the terminal channels facilitates winding wiring and also effectively fixes the wire fixing device, preventing it from moving upwards.

[0098] The present invention also provides an electric motor, which includes the aforementioned motor wiring device 100.

[0099] The motor with a motor wiring device of the present invention can have the following effects:
