However, prior art 1 only insulates the dropper installed on the hull line to prevent an electric shock accident, and there is a problem in that the part of the dropper coupled to the connecting line and the catenary is exposed to the outside, resulting in a risk of an electric shock accident. As the catenary flows up and down, an impact is applied to the connecting line, and fatigue is accumulated, and there is a problem in that the connecting line is disconnected.

In particular, when a railroad car passes a catenary, since the connecting line has to support the catenary, the connecting line is not easily bent due to its rigidity. There was a problem in that the connection line was disconnected as it went down.

In addition, since the catenary clamp and the clamshell clamp are fixed by the bolt and nut, the bolt and nut are loosened according to the vibration generated as the railroad vehicle passes, and there was a problem in that the catenary is dropped off or is separated from the clamshell.

In addition, if the deflection amount of the catenary is changed, the length of the connecting line supporting the catenary must also be adjusted. However, it is difficult to easily understand the gap between the pavilion and the catenary. there was a problem with
