Description
Technical field
The utility model relates to a kind of computer networking linking device, in particular to a kind of RJ45 network information module.
Background technology
Network information module is the one of junctor in wiring system, and two netting twines can be connected to get up by it, to facilitate network to connect up, it is achieved the electrical continuity of wire. RJ45 network information module is one the most frequently used in network information module, and known RJ45 network information module is eight metal wires, and eight heart yearn one_to_one corresponding in extraneous grid line. For a local area network, general duration of service is longer, in long-time use procedure, it is easy to aging circuit,, especially using network information module this kind of grid line wiring place position, more easily there is the situation of loose contact aging circuit in the situation of loose contact, and circuit is once there is loose contact, network fault will be caused.
Extraneous grid line has 8 cores, but only 4 heart yearns and network chip connect, and other 4 cores are for telephone wire is reserved at first, but in fact at present almost without any the netting twine connecting local area network simultaneously for connecting phone, that is other 4 heart yearns are idle completely. In addition, road as known, grid line adopts twisted-pair feeder to be possible to prevent the mutual crosstalk of signal, but facts have proved, 4 idle heart yearns can also be used for communication.
A network twisted-pair cable has 8 cores, and 8 heart yearn order are such, and upwards, line mouth, to oneself, is followed successively by 1,2,3,4,5,6,7,8 to netting twine crystal head plane from left to right, and wherein, 1,2,3,6 for communication, and 4,5,7,8 is idle. Circuit intermediate connection point is numerous, is easy to occur the situation of loose contact, particularly the Web vector graphic time permanent after, the bad situation of wiring circuit contact more easily occurs.
Finding in practice, grid line 8 heart yearn occurs that the probability of loose contact is not impartial. In 8 heart yearns, 1,8 heart yearns occur that the probability of loose contact is maximum, and 2,7 heart yearns take second place, and 3,6 heart yearns are third, 4,5 heart yearns occur that the probability of loose contact is minimum, this is because netting twine is in repeated multiple times plug process, 1,8 heart yearns are positioned at two ends, the situation bent, be shifted more easily occur, thus loose contact the most easily occurs, conversely, 4,5 heart yearns are positioned at centre, occur that the probability of loose contact is just minimum.
In addition, existing network information module does not have pilot lamp, and this is inconvenient to find network fault. Meanwhile, existing network information module does not have lightning protection device yet, and terminal device is easily struck by lightning.
In order to solve once the middle a certain point cantact of circuit is bad, just likely cause this technical problem of network fault, simultaneously, there is no pilot lamp to solve existing network information module and there is no the problem of lightning protection device, the utility model discloses the RJ45 network information module that a kind of novel lightning protection two-wire in parallel has pilot lamp, this kind of new network information module enhances wiring circuit contact reliability, as long as single line loose contact can be avoided just to there will be the situation of network fault, and add lightning protection device, it is provided with in order to judge the LED pilot lamp whether communication signal is unimpeded simultaneously, by the detection module of wiring board, the working order of control LED, detection module is prior art, widespread use, when detection module detects that network adapter terminal device communication is normal, LED is bright, when detection module detects that network adapter terminal device cannot normally communicate, LED extinguishes, when part circuit breaks down, contribute to finding out fast fault cause, decrease the time of investigation needed for fault and workload.
Practical novel content
