Description

Technical Field

[0001] This utility model relates to the field of motor technology, and more specifically to a solderless wiring structure. Background Technology

[0002] In the manufacturing and repair of electric motors, the connection between the enameled wire and the power cord is a crucial step. Traditionally, this connection is primarily achieved through soldering. This method requires melting solder bars at high temperatures, adding flux, and then soldering the enameled wire and power cord together to secure them for power supply. However, this soldering method has several significant drawbacks and potential hazards. First, the molten solder at high temperatures can easily cause burns to operators, increasing safety risks during the work process. Second, even when using so-called lead-free solder, it may still contain a certain amount of lead. During the soldering process, the release of lead fumes poses a potential threat to the health of operators. Long-term exposure to lead fumes can lead to chronic poisoning, affecting the nervous and hematopoietic systems. Furthermore, the flux used in the soldering process releases slightly toxic gases when heated. These gases not only irritate the operator's respiratory tract and eyes, but long-term exposure may also cause other health problems. This necessitates that soldering operations be carried out in a well-ventilated environment with appropriate personal protective equipment, increasing the complexity and cost of the operation. Another concern is the consistency of soldering quality. The quality of soldering largely depends on the skill and experience of the operator. The soldering quality can vary between different operators, and even among the same operator at different times. This can lead to unstable electrical performance at the connection points, affecting the overall performance and reliability of the motor. Finally, traditional soldering methods are inefficient in mass production. Each connection point requires individual soldering, which is time-consuming and hinders production efficiency. Furthermore, the waste generated during soldering, such as waste solder dross and used flux, can also cause environmental pollution.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Summary of the Invention

[0004] The purpose of this utility model is to provide a stable, reliable, and non-detachable connection structure between the enameled wire and the power cord of a motor, which avoids environmental pollution and harm to human health, in order to overcome the shortcomings of the existing technology.

[0005] The present invention achieves the above-mentioned objective by adopting the following technical solution: a connection structure between an enameled wire and a power supply wire of a motor, characterized in that it includes an enameled wire and a power supply wire, the enameled wire is provided with a riveting section that has undergone enamel removal treatment, the metal core of the power supply wire is riveted to the riveting section by a metal strip, and after riveting and fixing, an insulating sleeve is inserted for insulation protection treatment.

[0006] As a further explanation of the above scheme, the riveting section of the enameled wire is stacked with the power wire and fixed by riveting within the die slot of the riveting equipment.

[0007] Furthermore, the length of the riveted section after paint removal is 3-8mm, and the stacking length of the metal core of the power cord is consistent with that of the riveted section to ensure stable contact between the two.

[0008] Furthermore, the riveting section of the enameled wire is wound around the power cord and fixed by riveting within the die slot of the riveting equipment.

[0009] Furthermore, the metal strip is 5-10mm long and is clamped between the riveted section of the enameled wire and the outside of the metal core of the power cord.

[0010] Furthermore, the metal strip is a copper strip with a thickness of 0.5-2mm.

[0011] Furthermore, an insulating sleeve is pre-installed outside the power cord. The insulating sleeve is a heat-shrink tubing with a diameter larger than that of the enameled wire. The insulating sleeve is heated and shrunk to secure it at the riveting position between the enameled wire and the power cord.

[0012] The beneficial effects that can be achieved by adopting the above-mentioned technical solution in this utility model are as follows.

[0013] This invention uses enameled wire and power cord to be fixed by riveting. The enameled wire has a riveting section that has undergone enamel stripping treatment. The metal core of the power cord is riveted to the riveting section with a metal strip. After riveting and fixing, an insulating sleeve is inserted for insulation protection. This connection method avoids the high-temperature operation of traditional soldering methods, eliminates the generation of lead fumes and toxic gases, and improves the stability of connection quality and production efficiency through a standardized riveting process. It has the advantages of improving operational safety, reducing health risks, and improving connection quality stability and production efficiency. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] like Figures 1-2As shown, this utility model relates to a connection structure between an enameled wire and a power cord for a motor, aiming to solve the problems of high-temperature burns and lead fume hazards. The connection structure includes an enameled wire 1 and a power cord 2. The enameled wire 1 has a riveted section 1-1 that has undergone enamel stripping treatment. The metal core 2-1 of the power cord is riveted to the riveted section 1-1 using a metal strip 3. After riveting and fixing, an insulating sleeve 4 is inserted for insulation protection. Direct contact between the riveted section 1-1 of the enameled wire 1 and the metal core 2-1 of the power cord 2 avoids the need for high-temperature treatment during welding. The metal strip 3 riveting between the metal core 2-1 of the power cord 2 and the riveted section 1-1 eliminates the need for high-temperature heating, thus avoiding the risk of high-temperature burns. The insulating sleeve after riveting and fixing not only provides electrical insulation but also further ensures the mechanical stability and safety of the connection.

[0023] In specific implementation, the riveting section 1-1 of the enameled wire is stacked with the power line and fixed by riveting within the die slot 5-1 of the riveting equipment 5. It is worth noting that, besides stacking, the riveting section of the enameled wire and the power line can also be connected by winding. The metal strip is 6mm long and is clamped around the outside of the riveting section of the enameled wire and the metal core of the power line. The metal strip is preferably a copper strip with a thickness of 1mm. The length of the riveting section after the enamel removal treatment is 5mm, and the stacking length of the metal core of the power line is consistent with the riveting section, ensuring stable contact between the two to guarantee good conductivity and mechanical strength. Simultaneously, the material and thickness of the metal strip can be selected to adapt to different current load requirements, ensuring the reliability and stability of the electrical connection. As a preferred implementation, the metal strip can be precisely positioned and clamped through the die slot during the riveting process, ensuring the consistency and reliability of the riveting effect. An insulating sleeve is pre-placed outside the power line, and the diameter of the insulating sleeve is larger than that of the enameled wire. The insulating sleeve can be made of polyolefin material with good heat shrinkage properties, ensuring that no harmful gases are generated during heating, and possessing good insulation performance and mechanical strength. This material shrinks upon heating, tightly wrapping around the riveting position. Heating can be achieved using a hot air gun or other heating equipment to ensure the insulating sleeve shrinks evenly and secures itself at the riveting position. As a preferred embodiment, the insulating sleeve can be pre-placed outside the power cord before riveting and then heated after riveting. This ensures that the insulating sleeve will not move during the heating and shrinking process, guaranteeing the reliability of the insulation effect. This connection structure, using metal strip riveting, avoids the high-temperature burns and lead fume hazards that may occur during high-temperature welding. After riveting and fixing, the insulating sleeve is inserted for insulation protection, which not only improves the safety and reliability of the connection but also simplifies the operation process and reduces operational difficulty and danger.

[0024] Specifically, the riveted section of the enameled wire undergoes a stripping process, allowing it to directly contact the metal core of the power cord, thus avoiding the need for high-temperature welding. The metal strip riveting method not only simplifies the connection process but also improves the mechanical strength and stability of the connection. The use of an insulating sleeve further ensures electrical insulation and mechanical protection. The overall structure is simple and easy to operate, making it suitable for various motor manufacturing and maintenance scenarios.

[0025] Compared with existing technologies, this invention employs a riveting section that has undergone enamel stripping treatment, allowing for better contact between the enameled wire and the metal core of the power cord, thereby improving connection reliability. The use of metal strip riveting provides a reliable mechanical connection, avoiding the hazards of high-temperature soldering. Insulation protection through the insertion of an insulating sleeve ensures effective insulation at the connection point, further enhancing safety. Thus, this solution solves the problems of high-temperature burns and toxic gas emissions associated with traditional soldering methods, providing a safer and more reliable connection structure between the motor's enameled wire and the motor's power cord.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
