With the rapid development of electronic technology, electronic devices face increasingly complex electromagnetic environments, and electromagnetic interference (EMI) has become one of the key factors affecting the normal operation of the controller. To effectively suppress EMI and improve the controller's anti-interference capability, various shielding technologies have emerged.

[0003] Existing shielding technologies have the following drawbacks:

[0004] (1) Complex Structure: Some shielding designs employ complex structures, such as multi-layer shielding and labyrinth shielding. For example, patent application CN202817654U discloses a busbar trunking device that can reduce electromagnetic interference. It is a busbar trunking body with multiple metal conductors inside, each metal conductor is separated and insulated by an insulating material, and a magnetically conductive component is located inside the busbar trunking to block the magnetic lines of force generated by the busbar trunking. Although it can theoretically effectively shield electromagnetic interference, in actual manufacturing and assembly processes, problems such as difficulty in ensuring processing accuracy and assembly difficulties may arise, affecting the stability and reliability of the shielding effect.

[0005] (2) Heat dissipation problem: The shielding structure may hinder the heat dissipation of the controller, causing the controller temperature to rise during operation, affecting its performance and lifespan.

[0006] (3) Poor compatibility: The controller structures and working environments of different electronic devices vary, and some existing shielding designs may be difficult to adapt to various application scenarios, lacking versatility and compatibility. Utility Model Content

[0008] The objective of this utility model can be achieved through the following technical solutions:

[0009] A BUSBAR with integrated insulation and shielding functions includes: a conductive BUSBAR, an insulating layer, and a shielding layer, wherein the shielding layer is coated on the conductive BUSBAR, and an insulating layer is disposed between the shielding layer and the conductive BUSBAR.

[0014] Furthermore, a groove structure is provided on the surface of the shielding layer connected to the wide surfaces on both sides of the insulating layer, and the groove structure is uniformly arranged along the conductive direction of the conductive BUSBAR.

[0015] Furthermore, the insulating layer and the shielding layer are connected by the micro-platform structure and the groove structure, and the shape of the micro-platform structure matches that of the groove structure.

[0016] Furthermore, the shielding layer is aluminum foil, and the thickness of the aluminum foil matches the frequency of the electromagnetic interference.

[0017] Furthermore, when the frequency of the electromagnetic interference is high, the shielding layer is a highly conductive aluminum foil with a thickness of 0.01-0.03 mm; when the electromagnetic interference is low, the shielding layer is a high-resistivity aluminum foil with a thickness of 0.05-0.1 mm.

The micro-platform structure and the groove structure are matched in shape, and the insulating layer and the shielding layer are connected by the micro-platform structure and the groove structure. This structurally improves the mechanical interlocking force between the insulating layer and the shielding layer, thereby ensuring a reliable connection between the insulating layer and the shielding layer and effectively preventing relative displacement between the insulating layer and the shielding layer due to external forces or environmental factors during use.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This embodiment is based on the technical solution of the present invention and provides detailed implementation methods and specific operating procedures; however, the scope of protection of the present invention is not limited to the following embodiments.

[0028] Example 1

[0029] This embodiment provides a BUSBAR with integrated insulation and shielding functions, such as Figure 1 As shown, it includes: a conductive BUSBAR1, an insulating layer 2 and a shielding layer 3. The shielding layer 3 is coated on the conductive BUSBAR1, and the insulating layer 2 is disposed between the shielding layer 3 and the conductive BUSBAR1.

[0030] One end of the conductive BUSBAR1 is provided with a limit installation interface 4 and an electrical connection interface 5, and the other end is provided with an electrical connection interface 5. The limit installation interface 4 is rectangular and is used for limit during installation. The electrical connection interface 5 is circular and is used for reliable connection with other electrical components.

[0031] The conductive BUSBAR1 is made of high-purity copper, which has excellent conductivity, ensuring high efficiency in current transmission and reducing energy loss. At the same time, its good mechanical properties enable the BUSBAR1 to maintain a stable structure under various operating conditions, providing reliable physical support for electrical connections.

[0032] Insulation layer 2 is an insulating material, including polyester film. Polyester film has excellent insulation properties, which can effectively prevent current leakage and ensure the safe operation of electrical systems. It also has good heat resistance, chemical corrosion resistance and mechanical strength, which can effectively protect conductive BUSBAR1 under complex environmental conditions and extend its service life.

[0033] A cross-sectional diagram of the BUSBAR, which integrates insulation and shielding functions, is shown below. Figure 2 As shown, micro-platform structures 6 are provided on the surface of the insulating layer 2 connected to the wide sides of the shielding layer 3, such as... Figure 3 As shown, the micro-platform structures 6 are uniformly arranged along the conductive direction of the conductive BUSBAR1. Groove structures 7 are provided on the surface of the shielding layer 3, which is connected to the wide surfaces on both sides of the insulating layer 2, such as... Figure 3 As shown, the groove structure 7 is uniformly arranged along the conductive direction of the conductive BUSBAR1.

[0034] For the insulating layer 2 and the shielding layer 3, the insulating layer 2 and the shielding layer 3 are connected by a micro-platform structure 6 and a groove structure 7. The shapes of the micro-platform structure 6 and the groove structure 7 are matched, which structurally enhances the mechanical interlocking force between the insulating layer 2 and the shielding layer 3, thereby ensuring a reliable connection between them. This interlocking connection method not only enhances the physical connection strength between the two, but also effectively prevents relative displacement between the insulating layer 2 and the shielding layer 3 due to external forces or environmental factors during use, further improving the overall structural stability of the BUSBAR. At the same time, this design also helps to achieve more precise assembly during the manufacturing process, improving production efficiency and product quality.

[0035] The third shielding layer is made of aluminum foil. When selecting the aluminum foil material, its conductivity, shielding effectiveness, and mechanical properties are fully considered. The thickness of the aluminum foil is matched to the frequency of electromagnetic interference. For high-frequency electromagnetic interference environments, ultra-thin aluminum foil with high conductivity and a thickness of 0.01-0.03 mm is preferred. At high frequencies, its excellent conductivity allows it to quickly respond to interference waves, generating a strong reflected current and effectively blocking high-frequency interference. For environments dominated by low-frequency interference, aluminum foil with a thickness of 0.05-0.1 mm can be used, utilizing its higher resistance loss characteristics to better absorb low-frequency interference energy. Simultaneously, the aluminum foil is ensured to have sufficient flexibility and strength to prevent damage during processing and use, guaranteeing the durability of the shielding effect.

[0036] Meanwhile, to address the heat generated by excessive losses when current flows through the conductive BUSBAR1, heat dissipation holes 8 are evenly distributed on the narrow surfaces of the insulating layer 2 and the frequency blocking layer 3 coated on the conductive BUSBAR1, without affecting the shielding effect. This solves the overheating problem caused by excessive current. The position and number of holes can be adjusted according to the actual location to meet heat dissipation requirements without affecting the shielding effect. This heat dissipation design fully considers the thermal management needs of the BUSBAR in actual operation. By rationally arranging the heat dissipation holes 8, the heat exchange area between the conductive BUSBAR1 and the surrounding environment is effectively increased, accelerating heat dissipation and keeping the operating temperature of the conductive BUSBAR1 within a safe range, extending its service life. At the same time, it ensures that the shielding performance of the shielding layer 3 is not affected by the heat dissipation holes, achieving an organic combination of heat dissipation and shielding functions, and improving the overall performance and reliability of the BUSBAR.

[0037] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
