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。
2 支持部材
3 アームパイプ
3a 大径部
4 絶縁体
5 イヤー取付部材
5a 円筒部
6 イヤー
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により、絶縁体の接続部の断面積を減少させることなく、アームパイプ及びイヤー保持金具に密着させて結合することを特徴とする曲線引金具。
