To provide a trolley wire protective covering which is easy to lock and unlock with respect to a pair of assembled split bodies, excellent in operability, and convenient to handle.SOLUTION: A trolley wire protective covering is configured in a bobbin shape around a trolley wire by engaging a pair of split bodies 2, 2, respectively provided with a fitting concave part 8 and a fitting convex part 5, with a flange part 4 of a semi-cylindrical part 3 alternately in an axial direction of the semi-cylindrical part 3A. A first fixed part 9 projecting from an outside surface of the flange part 4 is provided with a guide hole 9a whose outlet is on a second fixed part 10 side. The second fixed part 10 projecting from an outside surface of the fitting convex part 5 is provided with an engaging concave part 10a for preventing relative movement in the axial direction by a stopper 11 entering thereto. The stopper 11 can be elastically contracted and deformed, penetrates the guide hole 9a with a narrow width, returns to its original shape when a tip thereof comes off, thereby preventing a locking projection 11d from coming off from the guide hole 9a, and locking the assembly of the split bodies 2, 2 at this position. In this state, a state display unit 11e is hidden by the first fixed part 9 and becomes invisible.SELECTED DRAWING: Figure 8
【課題】 組み付けた一対の分割体に対して簡単にロック及び解除操作できる操作性の良好で取扱いに好都合な吊架線保護カバーを提供する。【解決手段】 半円筒部3の鍔部4に嵌合凹部8と嵌合凸部5をそれぞれ備えた一対の分割体2,2を半円筒部3の軸線方向に互い違いに係合させて吊架線周りに糸巻状の吊架線保護カバーを構成する。鍔部4の外側面に突設した第1固定部9に、第2固定部10側を出口とするガイド孔9aを備える。嵌合凸部5の外側面に突設した第2固定部10に、ストッパ11が進入して軸線方向の相対移動を阻止する係合凹部10aを備える。ストッパ11は弾性的に縮小変形可能で、狭小幅のガイド孔9aを貫通し、先端部が抜け出たら原形に復帰してロック用突起11dがガイド孔9aから抜け止めされ、この位置で分割体2,2の組み付けをロックする。この状態で状態表示部11eが第1固定部9に隠れて目視不能となる。【選択図】 図8
