Description
【０００１】[0001]
本考案は電車線におけるトロリ線を接続するためのトロリ線接続金具に関する ものである。 The present invention relates to a trolley wire connecting fitting for connecting a trolley wire in a train line.
【０００２】[0002]
一般に長距離である電車線に用いられるトロリ線は適宜長さのものを接続して 使用されており、また、集電上における硬点の発生などにより局所的に磨耗が増 大したときにはそれらの部分を張り替えて使用されている。 In general, trolley wires used for long-distance train lines are used by connecting wires of appropriate length, and when local wear increases due to the occurrence of hard spots on the current collector, these trolley wires are used. It is used by replacing the part.
【０００３】 そのため、従来から図６および図７に示すようにいわゆるスプライザーと称さ れているトロリ線接続金具を用いてトロリ線同士を接続している。Therefore, conventionally, as shown in FIGS. 6 and 7, the trolley wires are connected to each other using a trolley wire connecting fitting called a so-called splicer.
【０００４】 このスプライザーと称されているトロリ線接続金具６１は互いに接続するトロ リ線６２，６３のそれぞれの先端面を中央部分で突き合わせてボルト６４で締め ることにより挟持片６５，６６でトロリ線６２，６３を挟持するとともに斜め上 方から螺入させた押しボルト６７，６８でトロリ線６２，６３を更に固定するも のである。The trolley wire connecting fitting 61, which is called a splicer, has end portions of the trolley wires 62 and 63 which are connected to each other butted at the central portions thereof and tightened with bolts 64 so that the contact pieces 65 and 66 are clamped. The trolley wires 62 and 63 are clamped and the trolley wires 62 and 63 are further fixed by push bolts 67 and 68 screwed obliquely from above.
【０００５】 しかしながら、前記スプライザーと称されているトロリ線接続金具６１は押し ボルト６７，６８でトロリ線６２，６３を直接固定する構成であるため、押しボ ルト６７，６８の先端によってトロリ線６２，６３が傷つけられて、その箇所が 断線する心配もある。However, since the trolley wire connecting fitting 61 called the splicer has a structure in which the trolley wires 62 and 63 are directly fixed by the push bolts 67 and 68, the trolley wire 67 is attached by the tips of the push bolts 67 and 68. There is a concern that 62 and 63 will be damaged and that part will be disconnected.
【０００６】[0006]
本考案が解決しようとする課題は、従来使用されているトロリ線接続金具はト ロリ線が損傷する心配がある、という点である。 The problem to be solved by the present invention is that the conventional trolley wire connecting metal fittings may damage the trolley wire.
【０００７】[0007]
前記課題を解決するため、本考案は、トロリ線の上部両側に形成された係止溝 条に係合する係止爪を内側下端縁に沿って形成した一対の挟持片を互いに対向配 置させてなり、互いに接続するトロリ線の接続先端を中央部分で突き合わせて前 記挟持片で接続するトロリ線接続金具において、挟持片によって挟持したトロリ 線を押圧固定するためのコッタが備えられていることを特徴とする。 In order to solve the above-mentioned problems, the present invention has a pair of sandwiching pieces, which have locking claws formed along the inner bottom edge, which engage with the locking groove formed on both upper sides of the trolley wire. In the trolley wire connecting metal fitting in which the connecting tips of the trolley wires to be connected to each other are abutted at the central portion and are connected by the clamping piece, a cotter for pressing and fixing the trolley wire clamped by the clamping piece is provided. Is characterized by.
【０００８】 前記の構成に加えて、ちょう架線への吊り具の係着部を設けることが好ましい 。In addition to the above-mentioned structure, it is preferable to provide an engaging portion of the hanging tool to the catenary line.
【０００９】[0009]
互いのトロリ線を中央部分で突き合わせて両挟持片でそれぞれを挟持させ、コ ッタによってトロリ線を押圧密着させて固定する。 The trolley wires are butted against each other at the central part, and are clamped by the two clamping pieces, and the trolley wires are pressed and brought into close contact with each other by a cotter to fix them.
