One side of the thermally conductive layer 5 is attached to the bottom of the first copper layer 2, and the other side of the thermally conductive layer 5 is attached to the top of the aluminum core 4. One side of the magnetic shielding layer 6 is attached to the bottom of the aluminum core 4, and the other side of the shielding layer 6 is attached to the top of the second copper layer 3. The thermally conductive layer 5 is made of alumina ceramic material with high thermal conductivity, and the magnetic shielding layer 6 is made of permalloy soft magnetic material with high magnetic permeability. More specifically, the first copper layer 2 and the second copper layer 3 are wrapped around the outside of the aluminum core 4 and composited by rolling. This design ensures a tight bond between the first copper layer 2, the second copper layer 3, and the aluminum core 4, thereby guaranteeing high efficiency and stability of current transmission. Simultaneously, a heat-conducting layer 5 and a magnetic shielding layer 6 are positioned between the first copper layer 2, the second copper layer 3, and the aluminum core 4. The heat-conducting layer 5 is made of high thermal conductivity alumina ceramic material, which enhances the heat dissipation capacity of the conductor and effectively reduces the operating temperature of the laminated busbar body 1. The magnetic shielding layer 6 is made of high permeability permalloy soft magnetic material, which reduces electromagnetic interference generated by the laminated busbar body 1 and improves electromagnetic compatibility, making it suitable for electronic equipment with strict electromagnetic environment requirements.

This enables quick docking of the stacked busbar body 1 with each module via the pluggable connector 8. The pluggable connector 8 uses multiple pins 10, and the surface of the pins 10 is specially gold-plated or silver-plated to reduce contact resistance. At the same time, the anti-misinsertion collar 9 sleeved on the outside of the pluggable connector 8 uses different colors to ensure more accurate connection, thereby greatly improving the installation and maintenance efficiency of the stacked busbar body 1.

Then, anti-misinsertion collars 9 of different colors are fitted onto the outside of the pluggable connector 8. When the stacked busbar body 1 is connected to each module, the color of the anti-misinsertion collars 9 on the outside of the pluggable connector 8 enables quick and accurate docking, thereby greatly improving the installation and maintenance efficiency of the stacked busbar body 1. Simultaneously, the stacked busbar body 1 is compositely rolled from a first copper layer 2, a second copper layer 3, and an aluminum core 4.
