[0002] A lightning arrester is a device that is connected between a conductor and the ground to prevent lightning strikes, and is usually connected in parallel with the protected equipment. A lightning arrester can effectively protect electrical equipment. Once an abnormal voltage appears, the lightning arrester will take effect and play a protective role. When the protected equipment is running under normal operating voltage, the lightning arrester will not take effect, and it will be regarded as a circuit breaker to the ground. During the wiring process of the lightning arrester, the conductive strip is suspended after the wiring is completed, which poses a certain safety hazard. Utility Model Content

The operating ring and the piercing wire clamp are fixedly installed on the left and right sides of the upper bracket, the lightning arrester is fixedly installed at the center of the upper bracket, the mounting bracket and the disconnector are positioned and installed at the tail end of the lightning arrester, the disconnector is connected to the conductive belt, and the mounting bracket frame is vertically fixed with a wire management rack by screws.

[0005] Preferably, the wire management rack is composed of an installation frame, an insulating partition, a ceramic insulating limit pressure plate and a driving rotating rod. The insulating partition is fixedly installed at the upper end of the frame body in the installation frame, and the ceramic insulating limit pressure plate is positioned and installed directly below the insulating partition by the driving rotating rod.

[0006] Preferably, the driving rotating rod is composed of a screw bracket, a fixing screw and a rotating screw, the screw bracket is fixedly installed by the fixing screw, and the inner diameter of the screw bracket is connected to the thread of the rotating screw.

[0007] Preferably, the rotating shaft installed on the top of the rotating screw is connected and installed with the ceramic insulating limit pressure plate

[0008] Compared with the prior art, the beneficial effect of the utility model is that the conductive belt passes through the position between the ceramic insulating limit pressure plates of the insulating partition of the wire management rack, and the screw is manually turned to drive the ceramic insulating limit pressure plate to move upward to fix the position of the conductive belt, thereby preventing the conductive belt from being suspended after wiring.
