<p>PURPOSE:To maintain an electric connection state of a connection piece and an energizing pole brace through the stable sandwiching force even when plastic deformation is caused in the connection piece by sandwiching the connection pieces of the respective electrode plates between an insulating side insertion port of the insulating plate of the electrode plates opposite to the respective electrode plates and the energizing pole brace. CONSTITUTION:An impressing electrode plate E1 has a connection side insertion port E15 for inserting a pole brace PV in one end and also has an insulating side insertion port E16 for inserting a pole brace PE in an insulating state in the other end. Similarly, a dust-collecting electrode plate E2 has an insulating side insertion port E26 and a connection side insertion port E25. The respective connection pieces E15a, E25a of the respective electrode plates E1, E2 are sandwiched between the insulating side insertion ports E26, E16 of the electrode pieces E2, E1 opposite to the respective electrode plates E1, E2 and the energizing pole braces PV, PE. Therefore the electric connection state of both the electroconductive members of the respective electrode plates and the electrode of a feeding unit is surely maintained in a long period.</p> |
