Connecting structure of ceramic high-voltage direct-current contactor

The utility model provides a connecting structure of a ceramic type high-voltage direct-current contactor. The connecting structure comprises a ceramic arc extinguishing cover, a binding post, a plastic arc extinguishing cover, a connecting wire, a circuit board, a gasket, a magnetic conductive plate and a coil. According to the utility model, the two connecting columns on the arc extinguishing chamber are welded with the corresponding wiring column connecting holes on the circuit board, and then the four binding posts on the ceramic arc extinguishing chamber are respectively inserted into the corresponding four binding post connecting holes on the circuit board. Then the gasket, the magnetic conductive plate and the coil are assembled in sequence, the outgoing lines on the coil also penetrate into the two corresponding outgoing line connecting holes of the circuit board, and finally all the bonding pads on the circuit board are welded. According to the design structure, positions of all welding procedures ca
