[0019] like Figure 1 As shown, the pressed busbar assembly includes three composite layers 1. The composite layer 1 is made of insulating material. After special formula design and curing treatment, the composite layer 1 has high strength, heat resistance and excellent electrical insulation properties. Reinforcement blocks 8 are installed on both sides of the composite layer 1. The reinforcement blocks 8 are welded and fixed to the composite layer 1, and blind holes 9 are opened on the reinforcement blocks 8.

[0020] Two PP cured insulating sheets 2 are installed between adjacent composite layers 1. The PP cured insulating sheets 2 are made of PP resin material. The PP resin material is prepared, molded and cured to obtain two PP cured insulating sheets 2. The two PP cured insulating sheets 2 are respectively covered on adjacent composite layers 1, and one side of the PP cured insulating sheet 2 is connected to one side of the composite layer 1.

[0021] A conductive main layer 3 is installed between the two PP cured insulating sheets 2. The conductive main layer 3 is prepared with a predetermined thickness and size. Both sides of the conductive main layer 3 are connected to one side of the two PP cured insulating sheets 2. Connection holes 4 are opened on the composite layer 1, the PP cured insulating sheet 2 and the conductive main layer.

[0022] The composite layer 1, the PP cured insulating sheet 2 and the conductive main body layer are pressed and cured using a dedicated pressing device. The pressure and temperature applied during the pressing process are precisely controlled according to the characteristics of the PP cured insulating sheet 2 to ensure good interface bonding while avoiding excessive compression that may lead to a decrease in insulation performance.

[0023] The laminated PP cured insulating sheets 2 have structures that engage with each other, ensuring that stable mechanical bonding and good electrical isolation can be formed after lamination.

[0024] A supporting plate 5 is installed on the conductive main body layer 3, and the supporting plate 5 is fixedly connected to the conductive main body layer 3. An extension block 6 is installed on the supporting plate 5, and the extension block 6 is perpendicular to the supporting plate 5. One side of the extension block 6 is welded and fixed to one side of the supporting plate 5. A through hole 7 is opened on the extension plate, and the through hole 7 is connected to the connecting hole 4.

[0025] Working principle: 1. By introducing PP cured insulation sheet 2 as the insulating medium and using the pressing process to connect the various parts of the busbar, it not only simplifies the assembly process of the busbar and reduces the production cost, but also improves the overall insulation performance and stability of the busbar, effectively preventing safety hazards caused by insulation failure during operation.

[0026] 2. Greatly improve the electrical performance of the busbar and extend its service life.

[0027] 3. The long-term use temperature of the PP cured insulating sheet 2 itself can reach 120°C under normal conditions, and it can withstand higher temperatures in the short term, for example, up to 150°C instantly, while maintaining good strength and performance. Therefore, the busbar pressed with the PP cured insulating sheet 2 as the insulating medium has better heat resistance.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
