[0021] This application discloses a conductive connecting aluminum busbar, including an aluminum busbar body 1. The aluminum busbar body 1 is irregularly shaped. Side ears 2 are provided at both ends of the aluminum busbar body 1. A connecting structure is provided on the side ears 2 at both ends of the aluminum busbar body 1. The connecting structure includes a connecting hole 3 provided on the side ears 2 at both ends. A symmetrical first positioning post 4 is provided on one side of the side ear 2 above and below the connecting hole 3. A symmetrical first positioning hole 5 is provided on one side of the side ear 2 to the left and right of the connecting hole 3.

[0022] refer to Figure 1 and Figure 2 The first positioning post 4 on one side of the side ear 2 is adapted to the corresponding second positioning hole on the connection point of the frequency converter. The first positioning hole 5 on one side of the side ear 2 is adapted to the corresponding second positioning post on the connection point of the frequency converter. An elastic gasket 6 is also provided on one side of the side ear 2. The elastic gasket 6 is made of beryllium bronze elastic alloy material. The elastic gasket 6 is provided with two sets of symmetrical through holes. One set of through holes corresponds to the symmetrical first positioning post 4 on one side of the side ear 2, and the other set of through holes corresponds to the symmetrical first positioning hole 5 on one side of the side ear 2. A corresponding bolt hole is also provided on the side ear 2 near the edge of the connection hole 3. A fixing bolt 7 is provided inside the bolt hole. The other end of the fixing bolt 7 is adapted to the bolt hole on the connection point of the frequency converter. More specifically, by using the side ears 2 at both ends of the aluminum busbar body 1 A symmetrical first positioning post 4 and a symmetrical first positioning hole 5 are provided on one side, so that the first positioning post 4 can be matched with the second positioning hole provided at the inverter connection point, and the first positioning hole 5 can be matched with the second positioning post provided at the inverter connection point. This makes it easier and more precise for the operator to connect the aluminum busbar body 1 to the inverter. At the same time, an elastic gasket 6 is provided on one side of the side ear 2. The elastic gasket 6 is made of beryllium bronze elastic alloy material, which has high conductivity. In the connection between the aluminum busbar body 1 and the inverter, it can effectively conduct current, ensure the stable operation of the system, and has excellent elastic performance. It can provide reliable elastic contact pressure at the connection point between the aluminum busbar body 1 and the inverter, ensuring the tightness of the connection, thereby increasing the actual conductive contact area, which is conducive to electron conduction, reducing contact resistance, and thus improving conductivity.

[0023] refer to Figure 3The surface of the aluminum busbar body 1 is also provided with heat dissipation fins 8. The heat dissipation fins 8 adopt a thin and dense design and are connected to the aluminum busbar body 1 by die casting or welding. The outer surface of the aluminum busbar body 1 is also provided with an insulating sleeve 9. More specifically, by providing heat dissipation fins 8 on the surface of the aluminum busbar body 1, the heat dissipation area can be increased and the heat dissipation effect can be improved. At the same time, the insulating sleeve 9 on the outer surface of the aluminum busbar body 1 can effectively reduce the risk of electric shock to workers.

[0024] refer to Figure 3 The aluminum busbar body 1 is composed of a multi-layer composite structure, including a high-strength aluminum alloy layer 10, a heat dissipation layer 11, and a high-conductivity layer 12. The high-strength aluminum alloy layer 10 is located in the innermost layer, the heat dissipation layer 11 is located in the middle layer, and the heat dissipation layer 11 is made of a highly thermally conductive aluminum-based silicon carbide composite material. The high-conductivity layer 12 is located in the outermost layer, and the high-conductivity layer 12 is a modified layer rich in highly conductive elements. More specifically, the high-strength aluminum alloy layer 10, located in the innermost layer, provides good mechanical support, ensuring that the aluminum busbar body 1 is not easily deformed or damaged during installation and use. The heat dissipation layer 11, made of a highly thermally conductive aluminum-based silicon carbide composite material, can effectively absorb and conduct the heat generated by the aluminum busbar body 1 during operation, reducing the temperature of the aluminum busbar body 1 and improving its current carrying capacity. The high-conductivity layer 12, being a modified layer rich in highly conductive elements, can efficiently conduct current and reduce resistance loss.

[0025] The implementation principle of a conductive aluminum busbar according to an embodiment of this application is as follows: In use, the connection holes 3 on the side ears 2 at both ends of the aluminum busbar body 1 are aligned with the connection points of the frequency converter, so that the symmetrical first positioning posts 4 on the side ears 2 are matched with the second positioning holes on the connection points of the frequency converter, and the first positioning holes 5 are matched with the second positioning posts on the connection points of the frequency converter. This makes it easier and more accurate for workers to connect the aluminum busbar body 1 to the frequency converter. At the same time, an elastic gasket 6 is set between the side ears 2 and the connection points of the frequency converter body, which can effectively conduct current and ensure the stable operation of the system. It can also provide reliable elastic contact pressure at the connection points of the aluminum busbar body 1 and the frequency converter, ensuring the tightness of the connection, thereby increasing the actual conductive contact area, reducing the contact resistance, and improving the conductivity. Meanwhile, heat dissipation fins 8 are set on the surface of the aluminum busbar body 1, which can increase the heat dissipation area and improve the heat dissipation effect. At the same time, an insulating sleeve 9 is set on the outer surface of the aluminum busbar body 1, which can effectively reduce the risk of electric shock to workers.
