[0040] Specific plan:

[0041] The copper busbar fixing structure consists of four parts: copper busbar (1 piece), PET insulation film one (1 piece), PET insulation film two (1 piece), and gaskets (7 pieces), which are used as a set.

[0042] 1. Copper busbar:

[0043] The copper busbar is made of pure copper, grade T2Y; it is used for connecting the positive and negative terminals of each module, serving as a current collector; there is a 90° bend on the left side of the copper busbar, after which the copper busbar changes from a horizontal to a vertical state, and there are three through holes with a diameter of φ5.5 on it; there are three 90° bends on the side of the copper busbar, after which the copper busbar changes from a horizontal to a vertical state, and there are two M4 press-fit nut holes on each bend; there are two φ15 through holes on the right side of the copper busbar.

[0044] The copper T2Y has good electrical conductivity;

[0045] The φ5.5 diameter through hole is used for connection with other copper busbars;

[0046] The M4's press-fit nut hole is used for connection with other copper busbars;

[0047] The φ15 through hole is used to place the FR4 gasket.

[0048] 2. PET insulating film one:

[0049] The PET insulating film is made of PET and is used for surface insulation of copper busbars. The PET insulating film has two φ5.5 through holes on the right side.

[0050] The PET has good insulation properties;

[0051] The φ5.5 through hole is used to fix the copper busbar.

[0052] 3. PET insulating film II:

[0053] The second PET insulating film is made of PET and is used for surface insulation of copper busbars. The second PET insulating film has two φ5.5 through holes on the right side.

[0054] The PET has good insulation properties;

[0055] The φ5.5 through hole is used to fix the copper busbar.

[0056] 4. Gaskets:

[0057] The gasket is made of organic epoxy glass cloth board (FR4); it serves as support and insulation; the gasket has a diameter of 15mm and a φ5.5 through hole in the middle.

[0058] The organic epoxy glass cloth board (FR4) has good flame retardant and insulation properties;

[0059] The φ5.5 through hole is used to fix the copper busbar.

[0060] The preferred embodiment of the copper busbar fixing method of this utility model is as follows:

[0061] The copper busbar fixing structure consists of four parts: one copper busbar, one PET insulating film, one PET insulating film, and seven gaskets, used as a set. Figure 1 , Figure 2 , Figure 3 As shown.

[0062] The copper busbar has three φ5.5 through holes 1 for connection with other copper busbars; it also has six M4 press-fit nut holes 2 for connection with other copper busbars; and two φ15 through holes 3 for placing FR4 washers, such as... Figure 4 .

Two mounting holes with good insulation properties are formed on the copper busbar using FR4 gaskets, PET insulating film one, and PET insulating film two. These two mounting holes allow the copper busbar to be securely fixed to the housing. Two FR4 gaskets are heat-pressed onto PET insulating film one to prevent fasteners from scratching the insulating film during copper busbar fixing. Three FR4 gaskets are heat-pressed onto PET insulating film two to maintain a certain distance between the copper busbar and the housing for ventilation and heat dissipation. The recommended assembly method is as follows: Figure 8 , Figure 9 .

[0067] This copper busbar fixing structure is simple in design, easy to assemble and disassemble, has good manufacturability, and is neat and aesthetically pleasing. It satisfies the electrical parallel connection function while saving space.
