Abstract
【解決手段】 曲線引金具1を、電車線路の側部に設けられた電車線柱などの構築物に支持部材を介して結合される支持部材2と、支持部材2に一端が固着されるアームパイプ3と、アームパイプ3の他端に一端が接続される絶縁体4と、絶縁体4の他端に固着されるイヤー取付金具5と、トロリ線を把持するイヤー6とで構成する。絶縁体4の一端部はアームパイプ3の先端部の大径部3aに挿入て圧縮接続し、他端部はイヤー取付金具5に挿入して圧縮接続する。
【選択図】 図1
Description
本発明は、孔加工を施すことなく絶縁体をアームパイプに接続することで、接続部での絶縁体の強度低下を無くすと共に、軽量化及びコストダウンを図り、また破断の原因となる雨水の侵入を防ぎ、さらに組み付けの作業時間を短縮する曲線引金具を提供することを課題としてる。
図において、曲線引金具1は、支持部材2、アームパイプ3、絶縁体4、イヤー取付金具5、イヤー6で構成される。

Claims (1)
- 電車線路の側部に設けられた支持構造物に支持金具を介して連結される支持部材と、基端部が支持部材に固着されて上方に湾曲しつつ延びるアームパイプと、アームパイプの先端部に固着された絶縁体と、絶縁体に固着されるイヤー保持金具と、このイヤー保持金具に保持されトロリ線を把持するイヤーとを具備し、
前記絶縁体の一端部はアームパイプに、他端部はイヤー保持金具に挿入され圧縮接続されることを特徴とする曲線引金具。
