Abstract
A cylindrical insulating rod 2 and a connecting rod 3 are connected to each other by a metallic shield ring 5 and a connecting pin 4. The metallic shield ring 5 has second shield portions 51 and 52 for electrical field relaxation on the external surface, and in which an inserted end receiving portion 21 of the insulating rod 2 is inserted. The connecting pin 4 is inserted through the metallic shield ring 5, the inserted end receiving portion 21 of the insulating rod 2 and an end portion of the connecting rod 32. The insulation-operating rod is capable of being small-sized, and has stable mechanical and electrical characteristics.
