Moving contact and direct action type isolator

The utility model relates to a moving contact and direct action type isolator, direct action type isolator include moving contact, insulating pull rod, tee bend stationary contact seat, work and touch seat and run -on, and the moving contact passes through screw -thread fit with insulating pull rod and realizes the transmission, and the moving contact includes the sleeve of electrically conductive body and insulator material, and the moving contact transmission is realized with insulating pull rod screw -thread fit to the sleeve. The electrically conductive body of insulating pull rod and moving contact passes through that the insulating sleeve is indirect to be connected, and the insulating sleeve is the insulator, and in the moving contact motion process, piece on -conductive that the friction produced can not influence field distribution, has avoided the electrically conductive hidden danger of bringing of piece, and work is touched seat and run -on and has directly been cast an organic whole, better improvement the interior field distribution of air chamber, it is concentrated to locate can not form the field intensity at this, is favorable to through -flowly.
