A connection apparatus of a light arm for an electric cable is provided to install the electric cable on the light arm without the limit of regulation of the electric cable by selectively adjusting a height between a first connection ring body and a second connection ring body. A first connection ring body(110) is installed on an upper part of an electric pole so that a light arm is installed on an upper end of the electric pole, and includes a plurality of connection pieces(112) having connection holes(111) and protrusively formed on an upper plane, a couple of first stepped units(114) having first fixed holes(113) connected with an installation hole(H) so that the light arm having the installation hole(H) on an outer circumferential plane is connected by a bolt, a plurality of first connectors(116) having first coupling holes(115), and a couple of connection pipes(118) having opened first bolt holes(117). A couple of supporting bolts(120) are connected to cross with the connection hole(111) to install the first connection ring body(110) at an upper part of the electric pole. A plurality of first pressing bolts(130) are connected to each of the first coupling holes(115) to fix the first connection ring body(110) on an outer circumferential plane of the electric pole. A first cross groove(131) is formed on a side of the first pressing bolt(130). A first rubber pad(133) for closely adhering the electric pole to the other end is attached to the plurality of first pressing bolts(130). A second connection ring body(140) is installed on a lower part of the first connection ring body(110) to install the light arm having a different height from the first connection ring body(110). A plurality of second pressing bolts(150) are connected to a second coupling hole(145) to fix the second connection ring body(140) on an outer circumferential plane of the electric pole. |
