DETAILED DESCRIPTION

[0030] See also Figures 1 to 7 As shown, according to an embodiment of the present application, the lead-out structure includes a first clip 1 and a second clip 2, and a wire fixing structure 3 is provided on the first clip 1. The first clip 1 can be fixedly connected to the second clip 2 and limit the lead-out wire 21 within the wire fixing structure 3. The second clip 2 is made of a rigid material, and the wire fixing structure 3 is made of a flexible material.

[0031] The second clip 2 of the lead-out structure is made of a rigid material, which can ensure that the lead-out structure is reliably fixed and will not fall out. The fixed wire structure 3 is made of a flexible material, which can avoid the problem of hard contact between the fixed wire structure 3 and the lead-out wire 21 causing the angle edge of the fixed wire structure to scratch the lead-out wire. At the same time, the flexible material can effectively reduce the vibration of the lead-out wire 21 and prevent the vibration of the lead-out wire 21 from being transmitted to the wiring structure, thereby effectively reducing the vibration noise caused by the vibration of the lead-out wire.

[0032] When the lead-out wire structure is applied to an air conditioner, it can effectively reduce the vibration of the lead-out wire 21 and prevent the vibration of the lead-out wire 21 from being transmitted to the air conditioner, thereby effectively avoiding noise problems.

[0033] In order to ensure that the connection and fixation between the outlet structure and the plastic-encapsulated stator are more reliable, the first clip 1 and the second clip 2 are preferably made of rigid material, and only the fixed wire structure 3 is made of flexible material, so that only the material for contact limiting the lead wire 21 is made of flexible material. The first clip 1 and the second clip 2, which are fixedly matched with the external structure, are made of rigid material, which can avoid deformation during the connection process and improve the connection stability of the outlet structure. In one embodiment, the first clip 1 and the second clip 2 are both made of nylon 66.

[0034] In one embodiment, a limiting groove 4 is provided in the middle of the second clip 2, and the wire fixing structure 3 is provided in the limiting groove 4. The first connecting structure is provided on both sides of the wire fixing structure 3 of the first clip 1, and the second connecting structure is provided on both sides of the limiting groove 4 of the second clip 2. When the first clip 1 and the second clip 2 are attached, the first connecting structure and the second connecting structure are fixedly connected. In this embodiment, the first clip 1 and the second clip 2 can be fixedly connected by the first connecting mechanism and the second connecting structure, so that the connecting force between the two can play the role of clamping the lead wire 21, and play a better role in limiting and guiding the lead wire 21.

[0035] In one embodiment, the first connecting structure includes a hook 5, and the second connecting structure includes a slot 6, so that the first connecting structure and the second connecting structure can form a snap connection, which can facilitate the connection and disassembly of the first clip 1 and the second clip 2, with a simple structure and easy operation.

[0036] In one embodiment, guide posts 7 are provided on both sides of the first clip 1, guide holes 8 are provided on both sides of the second clip 2, and the guide posts 7 are arranged in the guide holes 8. By utilizing the guiding cooperation of the guide posts 7 and the guide holes 8, the matching positions of the first clip 1 and the second clip 2 can be limited, ensuring that the matching positions of the first clip 1 and the second clip 2 correspond accurately, improving the better matching effect when the first clip 1 and the second clip 2 are connected together, and effectively ensuring the limiting effect of the lead-out wire 21.

[0037] In an embodiment not shown in the figure, the wire fixing structure 3 includes a protrusion arranged on the first clip 1, a wire groove 9 is arranged on the protrusion, and the lead wire 21 is arranged in the wire groove 9. The protrusion presses the lead wire 21 onto the second clip 2 through the wire groove 9. In this embodiment, the overall structure of the first clip 1 also adopts a flexible material, and the wire groove 9 is directly opened on the first clip 1. When the first clip 1 is pressed on the second clip 2, the wire groove 9 of the first clip 1 presses the lead wire 21 onto the bottom surface of the limiting groove 4 of the second clip 2, thereby limiting the lead wire 21.

[0038] In one embodiment, the wire fixing structure 3 can be detachably connected to the first clamping piece 1, so that the wire fixing structure 3 can be easily replaced and repaired on the first clamping piece 1. The wire fixing structure 3 adopts an independent and detachable structure, which can enhance the versatility of the lead-out structure. When replacing the lead-out wires 21 of different wire diameters, it is only necessary to replace the wire fixing structure 3 of the corresponding slot width, and it is not necessary to re-open the mold and replace the entire lead-out structure like the traditional lead-out structure. Therefore, the adaptability and versatility of the lead-out structure can be improved, and the mold opening cost can be reduced.

[0039] The wire fixing structure 3 is made of flexible material. Since the volume of the outlet structure is small, silicone rubber with good flexibility can be used. At the same time, silicone rubber also has good thermal stability and electrical insulation, which is more suitable for the outlet structure. The wire fixing structure 3 can also be made of other flexible materials with good thermal stability and electrical insulation, which can also meet the material requirements of the wire fixing structure 3 of this application.

[0040] In addition, since the wire fixing structure is made of flexible material, one groove width can adapt to lead wires 21 of various wire diameters, thereby enhancing the versatility of the wire fixing structure.

[0041] In one embodiment, the wire fixing structure 3 includes a first wire clamp 10 and a second wire clamp 11. When the first wire clamp 10 and the second wire clamp 11 are pressed together, a wire groove 9 is formed between the first wire clamp 10 and the second wire clamp 11. The lead wire 21 is located in the wire groove 9. The first wire clamp 10 and the second wire clamp 11 are connected by a connecting portion 12. The connecting portion 12 is provided with a wire hole 13 for the lead wire 21 to pass through. In this embodiment, the wire fixing structure 3 is provided with two wire clamps, which can be used to cooperate and clamp the lead wire 21. Since both wire clamps are supported by flexible materials, the lead wire 21 can be fixed more effectively.

[0042] In one embodiment, the first wire clamp 10 is provided with convex strips 22, and the second wire clamp 11 is provided with wire grooves 9. The convex strips 22 on the first wire clamp 10 correspond to the wire grooves 9 on the second wire clamp 11 in position and shape. In this embodiment, the first wire clamp 10 is connected to the second wire clamp 11 at the tail by a connecting portion 12. The curved connecting portion 12 fits the first wire clamp 10 on the second wire clamp 11. The first wire clamp 10 is provided with convex strips 22 that are consistent with the groove shape but smaller in width than the groove width, so as to compress the lead wire 21, allow the rubber member to wrap the lead wire 21, and more effectively reduce the vibration of the lead wire 21, thereby effectively protecting the lead wire 21.

[0043] In an embodiment not shown in the figures, the first wire clamp 10 and the second wire clamp 11 are respectively provided with wire grooves 9 , and the wire grooves 9 on the first wire clamp 10 correspond in position to the wire grooves 9 on the second wire clamp 11 .

[0044] In one embodiment, the wire slot 9 is provided with an inclined slot section 14 at the wire inlet end. By providing an inclined slot section 14 at the wire inlet end of the wire slot 9, the lead wire 21 can be bent at the wire inlet end, and the bent lead wire 21 can reduce the force on the lead wire 21 at the welding point. When the lead wire 21 is pulled forcefully, the force point is set at the bending point of the lead wire 21, which can reduce the force at the welding point and prevent the lead wire 21 from falling off due to excessive force on the welding point. Moreover, the second wire clamp 11 is made of elastic material, and its friction coefficient to the lead wire 21 is greater than that of hard material, so the friction force is greater, which can further reduce the force on the welding point.

[0045] The number of slots 9 on the second wire clamp 11 is the number of motor lead wires 21 , and the slot width is set according to the wire diameter of the lead wires 21 . The slot width needs to have a tolerance of -0.2 or -0.3 mm so that the slot 9 can clamp the lead wires 21 .

[0046] In one embodiment, a mounting seat 15 is disposed at the bottom of the first wire clamp 10 , a mounting hole 16 is disposed on the first clamping piece 1 , and the mounting seat 15 is detachably disposed in the mounting hole 16 .

[0047] In one embodiment, the mounting seat 15 is fixedly engaged with the mounting hole 16 .

[0048] In this embodiment, the wire fixing structure 3 is an independent detachable structure, and utilizes the mounting seat 15 to cooperate with the mounting hole 16 on the first clip 1. The mounting seat 15 is T-shaped, and the tail size is larger than the size of the mounting hole 16. The elasticity of silicone rubber can be utilized to plug the tail of the mounting seat 15 through the mounting hole 16, and the interference fit can be used to fix the wire structure to prevent it from falling off. The interference fit will affect the difficulty and strength of assembly. According to the size of the mounting hole 16, the single-sided interference fit can generally be set to 1.5-2.5mm.

[0049] In one embodiment, the first wire clamp 10 and the second wire clamp 11 are an integrated structure, which can reduce the difficulty of forming the two and effectively avoid the loss of one of the wire clamps.

[0050] In one embodiment, a clamping block 17 is provided on the second clip 2, and the clamping block 17 is provided corresponding to the wire slot 9, and the structure of the clamping block 17 is adapted to the structure of the wire slot 9. In this embodiment, when the first clip 1 and the second clip 2 are clamped, the clamping block 17 on the second clip 2 can be used to further clamp the lead wire 21, thereby more effectively reducing the loosening of the lead wire 21.

[0051] In one embodiment, the first clip 1 and the second clip 2 are connected by a connecting strip 18. The connecting strip 18 can be made of the leftover material of the outlet structure itself, which can facilitate the connection and separation of the first clip 1 and the second clip 2.

[0052] According to an embodiment of the present application, the motor includes a housing 19 and a wire outlet structure. The housing 19 is provided with a wire outlet 20 . The wire outlet structure is the above-mentioned wire outlet structure. The first clip 1 of the wire outlet structure is fixed on the wire outlet 20 .

[0053] When assembling the lead-out structure on the motor, press the mounting seat 15 of the wire fixing structure 3 into the mounting hole 16 of the first clip 1 to fix the wire fixing structure 3 on the first clip 1; install the first clip 1 on the lead-out port 20 of the motor stator; set the lead-out wire 21 in the wire groove 9 of the second wire clamp 11; close the first wire clamp 10 so that the convex strip 22 on the first wire clamp 10 is inserted into the wire groove 9 and pressed on the lead-out wire 21; close the second clip 2 to clamp it; finally, press the motor end cover to compress the second clip 2.

[0054] It is easy for those skilled in the art to understand that the above-mentioned advantageous methods can be freely combined and superimposed without conflict.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application.
