<p><P>PROBLEM TO BE SOLVED: To obtain a grounding wire extraction fastener in which an earthing wire can be housed in an electric pole, measurement of grounding can be executed, by simply extracting the grounding wire from an earthing wire extraction hole, when the grounding is measured, whose installation work is easy and whose structure is simple, which can be manufactured inexpensively, and with which the grounding wire extraction hole can be covered neatly. <P>SOLUTION: The ground wire extracting fastener is composed of an openable/closable ground wire extracting fastener body, which can be detachably fitted to the earthing wire extraction hole of the electric pole and in which a hinge part is formed to the tip part capable of taking-out/putting-in the inserted ground wire from the ground wire extraction hole, an earthing wire insertion recessed part formed closely to the tip part of the ground wire extraction fastener, and a locking piece, which is formed to the rear end part of the ground wire extraction fastener body and for pulling out the ground wire extraction fastener body from the ground wire extraction hole by using a jig. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
