[0011] Through the above technical solutions, O-rings and gaskets can ensure the sealing effect between the terminal and the insulating shell.

[0012] Furthermore, the terminal block is made of metal material, specifically copper metal material with conductivity and corrosion resistance, preferably copper metal material with high conductivity.

[0013] Through the above technical solutions, the copper material can ensure good corrosion resistance and stable conductivity of the terminals.

[0014] Furthermore, the number of terminals is increased to one, and it is located in the middle of the insulating shell of the reactor body.

[0015] Furthermore, the wiring terminals are fixedly installed on the outer end of the reactor body by bolts, and the bolts are made using a tin-plating process.

[0016] Through the above technical solutions, the tin plating process gives the bolts good corrosion resistance and strength.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] In this application, the reactor body and its insulating shell, along with the additional terminals added to the outer end of the insulating shell, effectively expand the application range and effect of the air-core reactor through the combined action of the internal copper washers, terminal parts, O-rings, terminals, gaskets, connecting plates, cap nuts, thin nuts, pressure rings, and nut parts.
