To provide a catenary wire protection cover which is constituted of an integrally-moldable single body, can reduce a manufacturing cost, and is easy in attachment work.SOLUTION: A catenary wire protection cover 1 is constituted which is interposed between a support metal fixture for suspending and supporting a trolley wire cabled at an upper part of a train track to a catenary wire M, and the catenary wire M, and prohibits mutual contact. The catenary wire protection cover 1 comprises: an elastic synthetic resin-made main body 2 which is formed into a cylindrical shape so as to surround the catenary wire M, is opened in an axial direction at both end edges, penetrates internally and externally, and has a spiral introduction groove 4 which is elastically and expansively deformed so as to accept the catenary wire M; and flange parts 3 which extend to the outside in a radial direction from both end parts of the main body 2, and constrain the support metal fixture in an axial direction between the flanges. The main body 2 comprises three threads of elongation/contraction grooves 5, 6 and 7 which are formed in parallel with the introduction groove 4, and expedite an elastic deformation of the introduction groove 4. The catenary wire M is inserted into the main body 2 through the introduction groove 4 while making the main body 2 rotate around the catenary wire M.SELECTED DRAWING: Figure 1

    【課題】 一体成形が可能な単一体で構成して制作コストの低廉化を図ると共に、装着作業が容易な吊架線保護カバーを提供する。【解決手段】 電車線路の上方に架設されたトロリ線を吊架線Mに吊支する支持金具と吊架線Mとの間に介設され、相互の接触を阻止する吊架線保護カバー1を構成する。この吊架線保護カバー1は、吊架線M周りを取り囲むように円筒状をなし、両端縁に軸線方向に開口し、内外に貫通して、吊架線Mを受け入れるように弾性的に拡開変形する螺旋状の導入溝4を備えた弾性合成樹脂製の本体2と、本体2の両端部から半径方向外側へそれぞれ延出し、相互間に支持金具を軸方向に拘束する鍔部3とを具備させる。本体2は、導入溝4に並行し、導入溝4の弾性変形を促進する三条の伸縮溝5,6,7を具備させる。本体2を吊架線M周りに回転させつつ導入溝4を通して吊架線Mを本体2に挿通させる。【選択図】 図1
