【考案の詳細な説明】
本考案は、鉄塔の如き支持体に架空線と平行して布設さ
れる架空地線のジャンパー装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jumper device for an overhead ground line installed on a support such as a steel tower in parallel with an overhead line.
この種のジャンパー装置は、支持体に接続金具を介して
機械的に接続された２つの架空地線の相応する接続金具
間に接続され支持体に押え金具で固定されたジャンパー
線から戒っている。This type of jumper device is designed to prevent the jumper wire from being connected between the corresponding connecting fittings of two overhead ground wires mechanically connected to the support via a connecting fitting and fixed to the support with a holding fitting. There is.
従来技術では、このジャンパー線は両接続金具と押え金
具との間で上向きに彎曲していたので特に押え金具付近
の短い部分で無理な姿勢で強制的に平行に折返すように
曲げなければならないため架空地線に種々の原因で発生
する振動によってジャンパー線に大きな応力が作用しジ
ャンパー線が折損する事故が生じていた。In the conventional technology, this jumper wire was curved upward between both connection fittings and the holding fitting, so it had to be bent in an unreasonable position, especially at the short part near the holding fitting, so that it was bent parallel to the other side. As a result, vibrations generated on the overhead ground wire for various reasons cause large stress to act on the jumper wires, resulting in accidents in which the jumper wires break.
本考案の目的は、ジャンパー線に大きな応力がかかるこ
とがないようにした架空地線のジャンパー装置を提供す
ることにある。An object of the present invention is to provide a jumper device for an overhead ground wire in which large stress is not applied to the jumper wire.
本考案の実施例を図面を参照して詳細にのべると、図面
は本考案に係る架空地線のジャンパー装置１０を示し、
架空地線１２．１２’は鉄塔の如き支持体１４に接続金
具１６．１６’によって機械的に接続されて鉄塔間に所
定の弛度で支持されている。An embodiment of the present invention will be described in detail with reference to the drawings. The drawings show an overhead ground wire jumper device 10 according to the present invention,
The overhead ground wire 12.12' is mechanically connected to a support 14 such as a steel tower by a connecting fitting 16.16' and is supported between the steel towers with a predetermined slack.
ジャンパー装置１０は、接続金具１６．１６’間に接続
された撚線から戊るジャンパー線１８を備えている。The jumper device 10 comprises a jumper wire 18 that is cut from a strand of wire connected between fittings 16, 16'.
接続金具１６．１６’はジャンパー線１８の両端を圧縮
接続する斜上向きで相互に対向する方向に突出する口出
部分１６ａ、１６’ａを有する。The connecting fittings 16, 16' have outlet portions 16a, 16'a projecting obliquely upward and in mutually opposing directions for compressively connecting both ends of the jumper wire 18.
ジャンパー線１８は、接続金具１６゜１６′間で上向き
に彎曲する第１と第２の２つの彎曲部２０．２０’を有
し、またこれらの第１と第２の彎曲部２０．２０’の間
に一体に連続するコイル状部２２を更に有する。The jumper wire 18 has two curved portions 20.20', a first and a second curved portion, which curve upward between the connecting fittings 16° 16', and these first and second curved portions 20.20'. It further includes a coiled portion 22 which is integrally continuous therebetween.
押え金具２４はこのコイル状部２２の下方部分を支持体
１４の上面に固定している。A presser fitting 24 fixes the lower portion of the coiled portion 22 to the upper surface of the support 14.
このように、ジャンパー線１８が第１と第２の彎曲部２
０．２０’に一体に連続するコイル状部２２を有し、押
え金具２４がこのコイル状部２２の下方部分で支持体１
４に固定すると、ジャンパー線１８は押え金具２４の前
後で従来の平行折返のように無理な姿勢で曲げられるこ
とがなく撚線を長くしてその可撓性を充分に利用して取
付けられるので押え金具付近で好ましくない歪みが加わ
ることがない。In this way, the jumper wire 18 connects the first and second curved portions 2.
It has a coiled part 22 integrally continuous with 0.20', and a presser metal fitting 24 is attached to the support body 1 at the lower part of this coiled part 22.
4, the jumper wires 18 will not be bent in an unreasonable position before and after the presser metal fitting 24 as in conventional parallel folding, and the strands can be lengthened and installed by fully utilizing their flexibility. Undesirable distortion is not applied near the presser fitting.
本考案によれば、上記のように、ジャンパー線は押え金
具で固定される部分ではコイル状部として全体的に長く
してその可撓性を利用しつつ曲げるので押え金具付近の
部分で大きな応力を発生することがないから架空地線に
振動が発生してもジャンパー線が折損する事故を発生す
ることがない。According to the present invention, as mentioned above, the part of the jumper wire that is fixed with the presser metal fitting is lengthened as a whole as a coiled part and bent while taking advantage of its flexibility, so there is a large stress in the part near the presser metal fitting. Therefore, even if vibration occurs in the overhead ground wire, there will be no accident of breakage of the jumper wire.
