| Zusammenfassung: | To provide a current terminal fixture capable of stably running an electric current with a large current-carrying capacity in replacement work of an electric cable with an insulated surface due to deterioration.SOLUTION: A current terminal fixture effective in electric wire extension work includes: a roller chain 11 of orbit shape structure connected with contact shoes 10 permitting a stable contact with the ground by breaking an insulation film of a surface of an electric wire 1; a pressure roller 13 for curving an electric wire for rubbing breakdown of insulation film of an electric wire surface.SELECTED DRAWING: Figure 1
【課題】劣化により表面が絶縁化した電線の張替作業において、安定的に通電容量の大きな電流を流すことのできる電流端子器具を提供する。【解決手段】電線延線時の有効な電流端子器具は、電線１の表面の絶縁皮膜を破壊して地金と安定的に接触させることのできる接触子１０が複数接続された軌道形状構造のローラチェン１１と、電線表面の絶縁皮膜を擦り破壊させる為、電線を湾曲させる押付けローラ１３を備えている。【選択図】図１ |
