Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing technology, and in particular relates to a lead wire assembly for an aluminum wire motor of an air conditioner compressor. Background Technology

[0002] As is well known, the main raw materials for air conditioner compressor motors include copper, silicon steel sheets, and some insulating auxiliary materials. In recent years, the price of copper has remained high, posing a dual challenge to air conditioner compressor motor manufacturers: heavy cost pressure and supply chain transformation. This has forced them to accelerate material substitution, technological innovation, and market strategy adjustments. In contrast, aluminum is only one-third the price of copper. If the wire used in an air conditioner compressor motor is changed from copper to aluminum, the motor cost can be reduced by 30%-50%.

[0003] However, the chemical properties of aluminum prevent the enameled wire from being welded to the lead wire; therefore, crimping is commonly used in the industry. A key quality indicator for crimping is the compression ratio, which is typically required to be between 60% and 80%.

[0004] In a single-phase motor, the primary and secondary phases work together to generate a rotating magnetic field, thereby starting and running the motor. The primary phase is typically made of thicker enameled wire, capable of withstanding a larger current load; the secondary phase is typically made of thinner enameled wire, with higher resistance, capable of generating a larger current during startup. It is precisely because of this significant difference in wire diameter between the primary and secondary phases that, after crimping, the compression ratio of the primary phase in some aluminum wire motor models meets the requirements, while the compression ratio of the secondary phase does not. An excessively low compression ratio cannot guarantee an effective connection between the enameled wire and the lead wires, jeopardizing the motor's reliability, safety, and lifespan.

[0005] Therefore, we propose a lead wire assembly for an aluminum wire motor of an air conditioner compressor. Utility Model Content

[0006] The purpose of this invention is to provide a lead wire assembly for an aluminum wire motor of an air conditioner compressor. This assembly can simultaneously ensure that the compression ratio of both the main phase and the auxiliary phase of the aluminum wire motor meets safety requirements, thereby ensuring the safe and stable operation of the motor and improving its service life.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a lead wire assembly for an aluminum wire motor of an air conditioner compressor, comprising a flag-shaped crimp terminal, a main phase red lead wire, a first binding knot, a secondary phase white lead wire, a second binding knot, and a common phase black lead wire. The main phase red lead wire and the common phase black lead wire are internally made of 1.25mm² soft copper wire, and the secondary phase white lead wire is internally made of 1.5mm² soft copper wire.

[0008] In one embodiment, the main phase red lead, the secondary phase white lead, and the common phase black lead are arranged in a triangular pattern.

[0009] In one embodiment, the length of the main phase red lead is 150-154 mm; the length of the secondary phase white lead is 136-140 mm; and the length of the common phase black lead is 122-126 mm.

[0010] In one embodiment, the distance between the first ligature and the second ligature is 15-19 mm; the distance from the top of the main phase red lead to the first ligature is 43-47 mm; and the distance from the top of the secondary phase white lead and the common phase black lead to the first ligature is 33-37 mm.

[0011] In one embodiment, the stripping length of the tail of the main phase red lead, the secondary phase white lead, and the common phase black lead is 15-16 mm.

[0012] This utility model has the following beneficial effects: This invention uses 1.5mm² soft copper wire inside the white lead wire of the secondary phase, compared to the original three lead wires that all use 1.25mm² soft copper wire. This allows it to simultaneously meet the compression ratio requirements of the main and secondary phases of the aluminum wire motor, ensuring the safe and stable operation of the motor, while effectively reducing the heat generated by the motor and improving its service life.

[0013] This invention only adjusts the specifications of the secondary phase wire, without requiring any additional processes, and has advantages such as simple structure, convenient processing, and low cost.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
