<p>PROBLEM TO BE SOLVED: To make it possible to visually confirm the charging condition. SOLUTION: In the high-tension rubber or a plastic molded terminal 2 having a semiconductive layer 1 on the outermost layer, a part 3 of the semiconductivity layer 1 is removed, and a metal plate or rod 5 narrower than the region removed is embedded into an insulating material layer 4 of the removed part. Then, a luminescent lamp, which is caused to light up and flick by a voltage induced between the metal plate or rod 5 and semiconductivity layer 1, is electrically connected between the metal plate or rod 5 and semiconductivity layer 1.</p> |
