Description

Technical Field

[0001] The utility model relates to the technical field of routers, in particular to a lightning protection router shell. Background Art

[0002] Lightning protection is an important part of network management. Once a lightning attack occurs, network equipment may become scrap metal overnight and cause considerable economic losses. Routers are an important communication device in network equipment. Once attacked, they are likely to be damaged or burned, affecting the normal connection of the network. Although the power lines in the building are equipped with lightning protection equipment, in order to further ensure the safety of the router, lightning protection sockets are usually used to prevent the lightning induced voltage from being transmitted to the router through the power supply.

[0003] However, since lightning strikes can cause induced currents and generate strong electrical pulses and surges in the power supply, although the router can be protected from lightning to a certain extent through lightning protection sockets, the router itself has weak lightning protection capabilities, so it is still necessary to strengthen the router casing's ability to shield and guide lightning. To this end, we propose a lightning-proof router casing. Utility Model Content
