PROBLEM TO BE SOLVED: To alleviate impact to a slider caused by a pantograph, to suppress the transmission of the impact to a trolley line, to prevent vibration, and to prevent the fatigue fracture of the trolley line.SOLUTION: A connecting device 1 which connects a slider 22 of a section insulator and a trolley line T2 connects an ear 4 for gripping the trolley line T2 to a lower part of a connecting metal fitting 2, and supports a pair of slider support members 3 having slider grip ear 7 for gripping the slider 22 to an upper part. A buffer mechanism 5 having a viscoelastic body which is elongation/contraction- deformed by relative vertical movement between both the connecting metal fitting 2 and the slider support member 3 is interposed between the connecting metal fitting and the slider support part. The slider support part 3 comprises a slide rod 8 which protrudes upwardly from the slider grip ear 7, penetrates the connecting metal fitting 2, and screws a retention nut 9 to the metal fitting in the middle of the penetration. The viscoelastic body is accommodated in a lower holder 10 and an upper holder 11 around the slide rod 8, fixes the lower holder 10 to the slide rod 8, fixes the upper holder 11 to the connecting metal fitting 2, and fits it to an axial line direction in a nest shape.

    【課題】パンタグラフによるスライダへの衝撃を緩和して、トロリ線への伝達を抑制すると共に、振動を防止して、トロリ線の疲労破断を防止する。【解決手段】セクションインシュレータのスライダ22とトロリ線T2を接続する結合装置1は、結合金具2の下部にトロリ線T2を把持するイヤ4を結合し、上部にスライダ22を把持するスライダ把持イヤ7を有する一対のスライダ支持部材3を支持する。結合金具2とスライダ支持部材3との間に、両者間の相対上下動により伸縮変形する粘弾性体を具備する緩衝機構5を介在させる。スライダ支持部材3はスライダ把持イヤ7から上方に突出して結合金具2を貫通し、途上に抜け止め用のナット9を螺合させる摺動ロッド8を具備する。粘弾性体は、摺動ロッド8周りの下ホルダ10、上ホルダ11内に収容し、下ホルダ10を摺動ロッド8に、上ホルダ11を結合金具2に固定して軸線方向に入れ子式に嵌合させる。【選択図】図1
