Description

Technical fields:

[0001] This utility model relates to the field of motors, and in particular to a stable and fixed connection structure for motor connecting wires. Background technology:

[0002] Existing motors, especially those for fan lights, consist of a motor shaft and a stator module. The wires pass through the motor shaft and extend to the side. Copper wires on the stator module are connected to the wires. Then, connectors are attached using cable ties, and the metal ring inside the connector is pressed tightly with pliers. Two or three connectors are then bundled together with plastic cable ties to complete the wire connection. The problem with this method is that the motor heats up during operation, causing the plastic cable ties and connectors to soften, leading to them loosening or breaking, thus reducing the motor's lifespan. Utility model content:

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a stable and fixed connection structure for motor connection wires, which solves the problem in the prior art that the plastic cable ties and wiring nipples are prone to softening due to the heat generated by the motor during operation, resulting in them falling off or breaking, thus reducing the service life of the motor.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The purpose of this utility model is to provide a stable and fixed connection structure for a motor connecting wire, including a motor shaft and a stator module. A first through hole is provided at the axial center of the stator module, and the motor shaft is inserted into the first through hole. A second through hole is provided at the axial center of the motor shaft.

A wire is provided inside the motor shaft, and the wire extends from the second through hole to the third through hole and extends out. Several winding blocks are arranged around the axial center of the stator module, and coils are wound on the winding blocks. A fourth through hole is provided on the stator module, and the wire is electrically connected to the coil and then inserted into the fourth through hole for clamping and fixing the wire.

[0006] Furthermore, the fourth through hole is located near the third through hole.

[0007] Furthermore, the surface of the stator module is coated with an insulating coating.

[0008] Furthermore, the wire fixing clip is provided with a slot.

[0009] Furthermore, the fifth through hole is located at the axial position of the wire fixing clamp.

[0011] Furthermore, a scratch-resistant sleeve is provided inside the motor shaft, and the wire is placed inside the scratch-resistant sleeve.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] 1) This utility model describes a stable and fixed connection structure for a motor connecting wire, including a motor shaft and a stator module. A first through hole is provided at the axial center of the stator module, and the motor shaft is inserted into the first through hole. A second through hole is provided at the axial center of the motor shaft.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0023] like Figures 1 to 5 As shown, this embodiment provides a stable and fixed connection structure for a motor connecting wire, including a motor shaft 1 and a stator module 2. A first through hole 21 is provided at the axial center of the stator module 2, and the motor shaft 1 is inserted into the first through hole 21. A second through hole 11 is provided at the axial center of the motor shaft 1, and a third through hole 12 is provided on the surface of the motor shaft 1 near the stator module 2. The third through hole 12 is close to the stator module 2 so that the wire does not need to extend too far. The second through hole 11 and the third through hole 12 communicate. A wire is disposed inside the motor shaft 1, extending from the second through hole 11 to the third through hole 12 and then extending out. A [missing information - likely a typo, should be "…"] is provided around the axial center of the stator module 2. Several winding blocks 22 are provided, with coils wound on each winding block 22. The stator module 2 is provided with a fourth through hole 23. The wires are electrically connected to the coils. When energized, a magnetic field is generated to make the rotor rotate. The wire fixing clip 3 is used to clamp the wires and then inserted into the fourth through hole 23 to clamp and fix the wire fixing clip 3. The front diameter of the wire fixing clip 3 is smaller and the rear diameter is larger to facilitate insertion into the fourth through hole 23. As long as the wire fixing clip 3 clamps the wires and coils and inserts them into the fourth through hole 23 for fixation, there is no need for plastic cable ties and wiring nipples. This avoids the motor heating up and melting the plastic cable ties and wiring nipples, which would shorten the motor's life.

[0024] As an optional embodiment, the fourth through hole 23 is located close to the third through hole 12 in order to reduce the distance of the wires.

[0025] As an optional embodiment, the surface of the stator module 2 is coated with an insulating coating that can isolate the stator module 2 from the coil and prevent electrical conduction between them.

[0026] As an optional embodiment, the wire fixing clip 3 is provided with a slot 31, which is designed to facilitate opening and inserting the wire.

[0027] As an optional embodiment, the fifth through hole 32 is located at the axial center of the wire fixing clip 3. The fifth through hole 32 is designed to facilitate the insertion of the wire and prevent displacement.

[0028] As an optional embodiment, there are 2-3 fourth through holes 23, and each fourth through hole 23 is provided with a wire fixing clip 3. If a three-phase circuit is involved, three wire fixing clips 3 will be involved.

[0029] As an optional embodiment, a scratch-resistant sleeve is provided inside the motor shaft 1, and the wire is placed inside the scratch-resistant sleeve. The scratch-resistant sleeve plays a protective role in preventing the motor shaft 1 from scratching the wire and causing safety hazards.

[0030] In existing technologies, the heat generated by the motor during operation can cause plastic cable ties and connectors to soften, leading to loosening, detachment, or breakage, thus reducing the motor's lifespan. Therefore, a new method for connecting the motor's wiring is provided. A fourth through-hole 23 is provided on the stator module 2. The wire extends from the second through-hole 11 to the third through-hole 12 and is clamped using a wire clamp 3. The wire clamp 3 is then inserted into the fourth through-hole 23 for clamping and securing. When the wire clamp 3 holds the wire, its diameter is larger than the diameter of the fourth through-hole 23, while its end is smaller than the diameter of the fourth through-hole 23. This provides a secure connection, eliminating the need for plastic cable ties and connectors, and preventing the motor's heat from melting these components and shortening the motor's lifespan.

[0031] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
