PROBLEM TO BE SOLVED: To provide a support frame for a rigid electric train wire, capable of achieving easy miniaturization and cost reduction.SOLUTION: A support frame P1 for a rigid electric train wire includes a support frame body 11 of a T-shaped cross section, a trolley wire support part 12 at the lower end of a web 11a of the support frame body 11, and a connection plate fitting shoulder part 13 also serving as an ear protruding to the side in the midway of the web 11a of the support frame body 11. A connection plate 16 is fitted between a slope 21 on the lower surface of a flange 11b and a slope 22a of the shoulder part to be fixed by a bolt 17, so as to be mechanically and electrically connected to the support frame body in its longitudinal direction. A trolley line a is supported and fixed to the support frame body 11 by fixing an ear 14 by a bolt 15. Thus, as the fitting-in slope of the connection plate 16 and the fitting surface of the ear 14 are formed in one shoulder part 13, the support frame can be compact, and materials can be reduced to achieve cost reduction.SELECTED DRAWING: Figure 2
【課題】小型化が容易であるとともに、コストダウンを図り得る剛体電車線用架台を提供する。【解決手段】断面T字状の架台本体11と、その架台本体11のウェブ11a下端のトロリー線支持部12と、架台本体11のウェブ11aの途中に側方に突出するイヤー兼接続当板取付用肩部13とを有する剛体電車線用架台P1である。フランジ11b下面の傾斜面21と肩部の傾斜面22aの間に接続当板16を嵌めてボルト17止めして架台本体をその長さ方向に機械的及び電気的に接続する。トロリー線aはイヤー14をボルト15止めして架台本体11に支持固定する。この構成であると、接続当板16の嵌め込み用傾斜面とイヤー14の取付面を一の肩部13に形成するので、架台をコンパクトにし得るとともに、材料も少なくなってコストダウンを図ることができる。【選択図】図2
