Description

Technical Field

[0001] This utility model relates to the field of enameled wire technology, and more specifically, to a copper-clad aluminum enameled wire with a composite shielding layer. Background Technology

[0002] Aluminum-clad enameled wire is an advanced electromagnetic wire product. It uses a copper-clad aluminum conductor as its core, coated with an insulating varnish layer. The copper-clad aluminum material combines the excellent conductivity of copper with the lightweight properties of aluminum, effectively transmitting electrical energy while reducing wire weight and production costs. The insulating varnish layer isolates the conductor from the external environment, ensuring the normal operation of electrical equipment. This type of enameled wire is widely used in the manufacturing of various electromagnetic equipment such as motors, transformers, and solenoid valves, playing a crucial role in improving equipment performance and reliability. Copper-clad aluminum enameled wire with a composite shielding layer takes this a step further. The composite shielding layer effectively shields against external electromagnetic interference while reducing its own electromagnetic radiation, improving electromagnetic compatibility and meeting the high requirements of modern electronic equipment for signal transmission stability and anti-interference capabilities.

[0003] Currently, copper-clad aluminum enameled wires mostly adopt a single-layer shielding design, which has many shortcomings. Due to the limitations of materials and thickness, single-layer shielding is difficult to achieve deep shielding and cannot meet the requirements for comprehensive suppression of electromagnetic interference in complex electromagnetic environments. For high-frequency and high-intensity interference signals, single-layer shielding is prone to shielding effectiveness attenuation, leading to equipment failure or performance degradation. At the same time, in complex scenarios with multiple frequency bands and multiple interference sources, single-layer shielding, due to its simple structure, cannot simultaneously suppress interference of different frequencies and types.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] To address the problems in related technologies, this utility model proposes a copper-clad aluminum enameled wire with a composite shielding layer to overcome the aforementioned technical problems existing in the prior art.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A copper-clad aluminum enameled wire with a composite shielding layer includes copper-clad aluminum wire cores arranged at equal intervals. An insulation layer is provided around the copper-clad aluminum wire cores. A shielding component and an auxiliary component are provided around the copper-clad aluminum wire cores. The shielding component includes shielding component one and shielding component two, which are respectively disposed between the outer periphery of the copper-clad aluminum wire cores and the insulation layer. The auxiliary component includes an auxiliary component, which is disposed between the inner wall of the insulation layer and the outer wall of shielding component one and shielding component two.

[0008] Furthermore, to better ensure the shielding effect, the shielding component includes a first composite layer, which is disposed on the outer wall of the copper-clad aluminum wire core. A conductive layer is disposed directly below the first composite layer and is disposed on the copper-clad aluminum wire core.

[0009] Furthermore, for better multi-layer shielding effect, the first composite layer includes shielding layer one and shielding layer two, with shielding layer two disposed inside shielding layer one and adapted to shielding layer one.

[0010] Furthermore, to better ensure the shielding effect, the shielding component two includes a second composite layer, which is disposed on the outer wall of the six shielding layers two and the shielding layer one.

[0011] Furthermore, for better multi-layer shielding effect, the second composite layer includes shielding layer three and shielding layer four. A mounting groove is provided on one side of shielding layer three, and shielding layer four is disposed inside the mounting groove, with shielding layer three in contact with the inner wall of the insulating layer.

[0012] Furthermore, in order to better ensure the support effect of the copper-clad aluminum wire cores, the auxiliary component includes a support part, which is disposed on the outer wall of one of the copper-clad aluminum wire cores, and the outer wall of the support part is in contact with the other six copper-clad aluminum wire cores.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting up shielding components, the problem of insufficient shielding effectiveness of traditional copper-clad aluminum enameled wire single-layer shielding is effectively solved. Shielding layer one and shielding layer two in shielding component one work together, and shielding layer three and shielding layer four in shielding component two work together to provide all-round shielding against electromagnetic interference of different frequencies and types. This multi-layer composite shielding structure not only improves shielding effectiveness, but also enhances the adaptability of enameled wire in complex electromagnetic environments, ensuring that the equipment can still operate stably under high frequency and high intensity interference signals, significantly improving electromagnetic compatibility, and ensuring the stability and anti-interference capability of signal transmission.

[0015] (2) By setting auxiliary components, reliable support and fixation are provided for the shielding layer. The support part in the auxiliary components is made of high-strength insulating material. Its ring structure fits tightly against the outer periphery of the copper-clad aluminum wire core, effectively preventing the shielding layer from shifting or deforming during use. This not only enhances the stability of the shielding layer, but also extends the service life of the enameled wire, ensuring the long-term effectiveness of the shielding effect. The addition of auxiliary components enables the copper-clad aluminum enameled wire to maintain good electrical and mechanical properties under complex working conditions, further improving the reliability and operating efficiency of the equipment.

A conductive layer 7 is disposed directly below the first composite layer 6. The conductive layer 7 is made of a copper-nickel alloy with excellent conductivity.

The conductive layer 7 is tightly fitted to the copper-clad aluminum wire core 1, ensuring a good electrical connection, and simultaneously...

Shielding layer 8 is a copper layer, which mainly shields high-frequency interference signals, while shielding layer 9 is an aluminum layer, which mainly shields low-frequency interference signals. The two cooperate to provide preliminary all-round shielding against electromagnetic interference of different frequencies. Subsequently, shielding layer 11 and shielding layer 12 work together.
