Problems solved by technology
[0008] The network cable has 8 cores in total. Correspondingly, there are 8 cores on the distribution frame, but only 4 cores are used for communication, and the other 4 cores are originally reserved for telephone lines, but in fact there are almost no network cables connected to the LAN at the same time. It is used to connect the phone, that is to say, the other 4 cores are completely free

The invention provides a 10M / 100M local area network distribution frame with a four-level lightning protection system and capable of displaying a working state. By setting four-level lightning protection means such as a lightning protection metal coil, a piezoresistor and the like, the lightning protection reliability is enhanced, the lightning protection effect is greatly improved, and the four-level lightning protection system has a simple structure, a low cost and relatively great practicality. Meanwhile, a detection circuit arranged in a connecting line can detect the connection state of each port and a jumper, and display the connection state through an indicator lamp; and when an information connection point is not working normally, the indicator lamp displays red, so that the faultyinformation connection point of the distribution frame can be conveniently searched, and the maintenance efficiency of the distribution frame is improved.
Description
Technical field [0001] The invention relates to integrated wiring technology, in particular to a 10M / 100M local area network distribution frame with a four-level lightning protection system that can display working status. Background technique [0002] The integrated wiring system is the foundation of the network system. Computers and communication networks rely on the wiring system as the physical basis of network connection and the channel for information transmission. For a modern building, the integrated wiring system is like the nerves in the body. It adopts a series of high-quality standard materials, in a modular combination, after a unified planning and design, integrated into a standard wiring system, The systems of modern buildings are organically connected to provide a physical transmission medium for the integration of modern buildings. [0003] After the construction of the integrated wiring system is completed, users have not had a better way to handle the maintenanc...
