Lightning protection signal connecting line

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.

Description

technical field [0001] The invention relates to a signal line, in particular to a lightning protection signal connection line. Background technique [0002] TV is an indispensable electrical appliance in people's daily life. The signal required by TV is usually transmitted through signal lines. However, in thunderstorm weather, the signal line will be affected by lightning and lose its normal working ability. It can even cause dire consequences. Signal lines that cannot be protected against lightning not only cannot guarantee the safety of electrical appliances such as TVs, but also pose a threat to the safety of human life and property. [0003] It can be seen that there are still defects in the above-mentioned existing signal lines, which need to be improved urgently. [0004] In view of the defects of the above-mentioned existing signal lines, the designer has been engaged in the design and manufacture of such products for many years, has accumulated rich practical exper...

AI Technical Summary

Problems solved by technology

[0005] The main technical problem to be solved by the present invention is to overcome the defects of the existing signal lines and provide a lightning protection signal connection line, which overcomes the defects of the existing signal lines that reduce the safety of thunderstorms, and adds a grounding PCB board to absorb a large Part of the lightning strike energy, thereby improving the safety and reliability of the signal line
