The center of upper three crimpings in first separated time portion is located at three vertex of an equilateral triangle.
The horizontal component of crimping and vertical portion are hollow tubulose, and the internal diameter of pipe is greater than diameter of wire, sets on tube wall It is equipped with threaded hole, fastening bolt is set in threaded hole.
The inner wall of the pipe is provided with and the consistent spiral groove of conducting wire spiral.
First separated time portion and the second separated time portion use integral structure.
The surface in the first separated time portion and the second separated time portion is provided with zinc coat.
Crimping and conductor contact surface are provided with the conductive bed course for increasing the two contact area.
Compared with prior art, the present invention at least has the advantages that the present invention is provided with the first separated time portion and the Equinoctial line portion, the first separated time portion be include three crimpings, three crimpings are fixedly connected using first connecting rod between any two; Three crimpings and first connecting rod in the first separated time portion form inverted triangle, and the second separated time portion includes two crimpings, Two crimpings in the second separated time portion are in the same plane with the first two, separated time portion top crimping, and crimping is T-type, institute The horizontal component of T-type is stated along conducting wire axial direction, the vertical direction of T-type is vertical with conducting wire;It is adopted with the second separated time portion in the first separated time portion It is fixedly connected with the second connecting rod;In-site installation is convenient, and worker's working strength is small;" positive triangle " type tripartition conducting wire divides spacing It is easy to guarantee;Cracking separation rod can be doubled as, the usage amount of cracking separation rod is reduced, greatlys improve field erected safety.
Further, crimping and conductor contact surface are provided with the conductive bed course for increasing the two contact area, enhancing Its electric conductivity and conductive stability.
Further, the surface in the first separated time portion and the second separated time portion has zinc coat to can effectively prevent fitting and is corroded, It prolongs its service life, improves the safety of power supply line.
Further, crimping and conductor contact surface setting mention simultaneously for increasing the conductive bed course of the two contact area The stability of high conducting wire connection.
