架空線保持装置及びこれを用いた架空線保持方法

Retainer for overhead wire and method of retaining overhead wire using the same

Abstract

【課題】電線に装着されるブッシュを、スペーサに容易に着脱できるようにすることでスペーサの架空線への取付作業や付け直し作業を容易に行え、作業時間の短縮化を図り、また、ブッシュがスペーサから容易に脱落する恐れのない構成を提供する。 【解決手段】電線保持用の収容凹部3を備えたフック部4を有するスペーサ5と、フック部4に対して分離可能に構成され、電線2に装着されるブッシュ6とを備える。ブッシュ6を、電線2に着脱可能に装着される円筒状の本体部15と、本体部15から径方向に突設されてフック部4を挿通可能に開口された開口部16を具備する係止部17とを有して構成し、電線2をブッシュ6を介してフック部4の収容凹部3に収容した後に、係止部17の開口部16にフック部4を挿通させると共に係止部17をフック部4の外周面に形成された溝部11に係合させてブッシュ6をフック部4に装着する。 【選択図】 図3
PROBLEM TO BE SOLVED: To provide a structure capable of easily performing a work to attach/detach a spacer to/from an overhead wire, reducing work time, and eliminating the possibility of a bushing to be attached to the overhead wire easily dropping from the spacer, by making the bushing easily detachable from the spacer.SOLUTION: The retainer for an overhead wire comprises: a spacer 5 having a hook part 4 including a recessed housing part 3 for retaining a wire; and a bushing 6 having a detachable structure from the hook part 4, and to be attached to an electric wire 2. The bushing 6 comprises: a body part 15 having a cylindrical shape and detachably attached to the electric wire 2; and a locking part 17 projecting from the body part 15 in the radial direction and having an opening part 16 being opened so that the opening part can be inserted to the hook part 4. After the electric wire 2 is housed into the recessed housing part 3 of the hook part 4 through the bushing 6, the bushing 6 is mounted to the hook part 4 by inserting the hook part 4 into the opening part 16 of the locking part 17, and locking the locking part 17 to a groove 11 formed on the outer peripheral surface of the hook part 4.
