Description
Technical field
The utility model relates to a kind of RJ45 interface network adapter of computer networking, i.e. usual said network interface card.
Background technology
At present, known the most widely used RJ45 interface network interface card is made up of RJ45 network card interface and network card chip, and extraneous grid line first connects RJ45 network card interface, then connects network card chip.Extraneous grid line has 8 cores, but only has 4 heart yearns to be connected with network card chip, and other 4 cores are for telephone wire is reserved at first, but in fact at present almost without any connecting the netting twine of local area network (LAN) simultaneously for connecting phone, that is other 4 heart yearns are idle completely.In addition, road as known, grid line adopts twisted-pair feeder can the mutual crosstalk of anti-stop signal, but facts have proved, 4 idle heart yearns also can 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 network wire crystal joint plane from left to right, and wherein, 1,2,3,6 for communication, and 4,5,7,8 is idle.For domestic consumer's online, communication line generally connects switch from router, connect user again, circuit intermediate connection point is numerous, be easy to the situation occurring loose contact, particularly the Web vector graphic time permanent after, the bad situation of wiring circuit contact more easily occurs, once a certain point cantact is bad in the middle of circuit, just likely cause network failure.
Find in practice, grid line 8 heart yearn occurs that the probability of loose contact is not impartial.In 8 heart yearns, 1, there is the maximum probability of loose contact in 8 heart yearns, and 2,7 heart yearns take second place, and 3,6 heart yearns third, 4,5 heart yearns occur that the probability of loose contact is minimum, this is because netting twine is in repeated multiple times swapping process, 1,8 heart yearns are positioned at two ends, more easily occur the situation of bending, being shifted, thus the most easily there is loose contact, conversely, 4,5 heart yearns are positioned at centre, occur that the probability of loose contact is just minimum.
In order to solve once the middle a certain point cantact of circuit is bad, just likely cause this technical problem of network failure, the utility model discloses a kind of redundant line 10M/100M adaptive net card.
Summary of the invention
Namely can cause the deficiency of network failure to overcome a certain heart yearn loose contact of existing network interface card, the utility model provides a kind of redundant line 10M/100M adaptive net card, and this new network interface card avoids the situation that namely a certain heart yearn loose contact can cause net card failure.
The utility model solves the technical scheme that its technical problem adopts: after extraneous 8 core grid lines are connected with network card interface, only have 1, 2, 3, 6 heart yearns are connected with network card chip and are used for communication, other 4 heart yearns that is 4, 5, 7, 8 heart yearns are idle, simultaneously, find in practice, grid line 8 heart yearn occurs that the probability of loose contact is not impartial, in 8 heart yearns, 1, there is the maximum probability of loose contact in 8 heart yearns, 2, 7 heart yearns take second place, 3, 6 heart yearns third, 4, 5 heart yearns occur that the probability of loose contact is minimum, this is because netting twine is in repeated multiple times swapping process, 1, 8 heart yearns are positioned at two ends, more easily occur bending, the situation of displacement.
For this reason, the utility model provides a kind of redundant line 10M/100M adaptive net card, comprises RJ45 network card interface, connecting line and network card chip, described connecting line has 8 heart yearns, is followed successively by 1,2,3,4,5,6,7,8, feature of the present utility model is, 1,7,8 heart yearns are in parallel, and 2,5 heart yearns are in parallel, 3,4 heart yearns are in parallel, like this, even if the most easily occur that 1,8 heart yearns of loose contact disconnect simultaneously, connect owing to also having the 7th heart yearn, network interface card also can normally work, and there will not be network failure.
The beneficial effects of the utility model are, a kind of redundant line 10M/100M of the utility model adaptive net card is in parallel by 1,7,8 heart yearns, 2,5 heart yearns are in parallel, 3,4 heart yearns are in parallel, like this, even if the most easily occur that 1,8 heart yearns of loose contact disconnect simultaneously, connect owing to also having the 7th heart yearn, thus network interface card also can normally work, and there will not be network failure, avoid the situation that namely a certain heart yearn loose contact can cause net card failure.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is common 10M/100M adaptive net card circuit theory diagrams, and in the drawings, 1,2,3,4,5,6,7,8 is 8 core connecting lines, and connecting line connects RJ45 network card interface and network card chip.
Fig. 2 is the circuit theory diagrams of a kind of redundant line 10M/100M of the utility model adaptive net card.In the drawings, 1,2,3,4,5,6,7,8 is 8 core connecting lines, and connecting line connects RJ45 network card interface and network card chip, and wherein, 1,7,8 heart yearns are in parallel, and 2,5 heart yearns are in parallel, and 3,4 heart yearns are in parallel.
Embodiment
Embodiment as shown in Figure 2, a kind of redundant line 10M/100M adaptive net card, comprise RJ45 network card interface, connecting line and network card chip, described connecting line has 8 heart yearns, be followed successively by 1, 2, 3, 4, 5, 6, 7, 8, wherein, 1, 2, 3, 6 for communication, 4, 5, 7, 8 is idle, find in practice, grid line 8 heart yearn occurs that the probability of loose contact is not impartial, in 8 heart yearns, 1, there is the maximum probability of loose contact in 8 heart yearns, 2, 7 heart yearns take second place, 3, 6 heart yearns third, 4, 5 heart yearns occur that the probability of loose contact is minimum, this is because netting twine is in repeated multiple times swapping process, 1, 8 heart yearns are positioned at two ends, more easily occur bending, the situation of displacement.
