Abstract
The invention discloses a lightning protection signal connecting line. The lightning protection signal connecting line is composed of a copper core wire, a metal woven mesh and a lightning protection device. The metal woven mesh is located around the copper core wire. The lightning protection device is arranged around the metal woven mesh. The lightning protection device comprises shielding housing and a grounding PCB board and a capacitor which are located in the shielding housing. The grounding PCB board is composed of a thick wire, a thin thick and a multilayer structure. The multilayer structure is formed by superposing metal sheets and metal power-ceramic material mixed layers alternately. According to the invention, the grounding PCB board is used to guide a large current generated by lightning into the multilayer structure through the thick wire, the metal power-ceramic material mixed layers are melted rapidly under the action of the large current to absorb most of the lighting energy, the shielding housing, the grounding PCB board and the capacitor can be use to form the lightning protection device to play the lightning protection role in thunderstorm weather conditions, and the whole lightning protection signal connecting line has advantages of good safety and good practicability.
