Overhead line connecting device

The utility model relates to an overhead line connecting device. The overhead line connecting device comprises a fusiform conductive shell, two metal wire clamps, a conductive layer and a spring assembly. The fusiform conductive shell defines an accommodating cavity. And the two metal wire clamps are accommodated in the accommodating cavity, are respectively arranged at two ends of the fusiform conductive shell and are used for fixing wires to be connected. And the conductive layer covers one side, far away from the fusiform conductive shell, of the metal wire clamp and is used for increasing the conductive area. And the spring assembly is accommodated in the accommodating cavity, is arranged between the two metal wire clamps and is used for providing tension towards the two ends of the fusiform conductive shell for the two metal wire clamps. The overhead line connecting device can realize quick connection of the to-be-connected wires. When the overhead line connecting device is used, complex tools do not nee
