Description

Technical Field

[0001] This utility model belongs to the field of enameled aluminum wire welding technology, specifically relating to a welding wire structure for enameled aluminum wire of a DC brushless motor. Background Technology

[0002] Brushless motors are a common type of motor structure, consisting of a stator and a rotor, with enameled wire coils wound on the stator. In existing technologies, the enameled wire is pierced when the power cord terminal is inserted into the mating terminal for connection. While this can achieve connection and positioning, the piercing of the enameled wire's coating can cause instability, and the exposed aluminum wire and terminal can lead to corrosion. Furthermore, the pierced connection has a small contact area, which is difficult to meet market demands and limits the stability of use. Summary of the Invention

[0003] The purpose of this invention is to provide a welding wire structure for enameled aluminum wire in a DC brushless motor that has a reasonable structural design and is conducive to improving the stability of use.

[0004] The technical solution to achieve the purpose of this utility model is a welding wire structure for enameled aluminum wire of a DC brushless motor, including a stator with enameled aluminum wire and a power line connected to the enameled aluminum wire, with the end of the power line extending out of the power line insulation layer;

[0005] The end of the enameled aluminum wire is provided with a de-enameled wire head;

[0006] The enameled aluminum wire is wound around the power cord insulation layer of the power cord. The de-enameled wire end is twisted and connected to the end of the power cord. After the de-enameled wire end and the end of the power cord are wound together, they are fitted into the terminal piece and fixed with solder.

[0007] A further preferred embodiment is that the terminal component is an aluminum structural component or a copper structural component.

[0008] A further preferred embodiment is that the number of power lines is two-phase or three-phase.

[0009] A further preferred embodiment is that the number of turns of the enameled aluminum wire wound around the power cord insulation layer is three to six.

[0010] This utility model has positive effects: The structure of this utility model is reasonable. The enameled aluminum wire is wound on the insulation layer of the power cord, and the wire end without enameled layer is wound and connected to the terminal of the power cord, which can improve the stability of the connection. Then, it is sleeved in the terminal and welded and fixed, which not only ensures the reliability of the welding, but also helps to increase the contact area between the enameled aluminum wire and the power cord, ensuring the connection effect. It also helps to prevent the enameled aluminum wire from rusting, improves the connection strength of the overall structure, and has strong applicability. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] See Figures 1 to 2 As shown, a welding wire structure for enameled aluminum wire in a DC brushless motor includes a stator 2 with enameled aluminum wire 1 and a power line 3 connected to the enameled aluminum wire. The end of the power line extends out of the power line insulation layer 4. In this embodiment, the stator and the enameled aluminum wire are conventional structures of the prior art, and are simply applied. The power line insulation layer of the power line is a conventional structure of the prior art, and can be either copper wire or aluminum wire.

[0017] Furthermore, in this embodiment, the end of the enameled aluminum wire is provided with a de-enameled wire head; the de-enameled wire head is a knot where the enameled layer on the surface of the enameled aluminum wire has been scraped off, which can ensure the effectiveness and stability of conductivity when connected to the power line.

[0018] Furthermore, the enameled aluminum wire is wound around the power cord insulation layer of the power cord, with three to six turns. The de-enameled wire end is twisted and connected to the end of the power cord, and after being wound together, the de-enameled wire end and the power cord end are fitted into the terminal piece 5 and fixed with solder. The enameled aluminum wire wound around the power cord insulation layer ensures the stability of the connection and also protects the insulation layer. The twisted connection between the de-enameled wire end and the power cord end ensures the contact area and stability of the connection. The fitting and soldering of the terminal piece ensures the reliability and effectiveness of the connection, and also helps prevent oxidation and corrosion of the de-enameled wire end, extending its service life. The terminal piece is made of aluminum or copper.

[0019] In this embodiment, the number of power lines is either two-phase or three-phase. This is a conventional structure in the prior art and therefore not described in detail.

[0020] This utility model has positive effects: The structure of this utility model is reasonable. The enameled aluminum wire is wound on the insulation layer of the power cord, and the wire end without enameled layer is wound and connected to the terminal of the power cord, which can improve the stability of the connection. Then, it is sleeved in the terminal and welded and fixed, which not only ensures the reliability of the welding, but also helps to increase the contact area between the enameled aluminum wire and the power cord, ensuring the connection effect. It also helps to prevent the enameled aluminum wire from rusting, improves the connection strength of the overall structure, and has strong applicability.

[0021] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0022] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
