Abstract
The invention provides an 8-wiring-system network card. After an 8-core network cable is connected with a network card interface, four idle core wires are in parallel connection with four non-idle core wires and then are connected with a network card chip. The 8-wiring-system network card is characterized in that when one core wire of the 8-core network cable is disconnected, the network card work is not influenced. The four idle core wires can be in parallel connection with the four non-idle core wires before being led into a network card isolation transformer, and then are connected with the network card chip through the network card isolation transformer. In addition, the four idle core wires can be led into a network card isolation transformer, then are in parallel connection with the four non-idle core wires, and finally are connected with the network card chip. The two design ideas are identical, namely the four idle core wires are in parallel connection with the four non-idle core wires and then are connected with the network card chip.
Description
Affiliated technical field
The present invention relates to a kind of RJ-45 interface network adapter of computer networking, i.e. usual said network interface card.
Background technology
At present, known the most widely used RJ-45 interface network interface card is comprised of network card chip, network interface card isolating transformer, and the network interface card connection is that the computer PCI bus connects network card chip, and network card chip connects extraneous grid line by the network interface card isolating transformer.Extraneous grid line has 8 cores, but only has 4 heart yearns to be connected with network card chip, other 4 cores be at first for telephone wire reserved, but in fact at present almost without any the netting twine of connection local area network (LAN) simultaneously for connecting phone, that is to say that other 4 heart yearns are idle fully.In addition, just as we all know, grid line adopts twisted-pair feeder can prevent that stop signal crosstalks mutually, but facts have proved, computer adopts new network interface card of the present invention to work, and that is to say that the present invention is rational fully.
Summary of the invention
Can cause the deficiency of net card failure in order to overcome a certain heart yearn loose contact of existing network interface card, the invention provides a kind of 8 line network interface card processed, this 8 line network interface card processed has avoided a certain heart yearn loose contact can cause the situation of net card failure.
The technical solution adopted for the present invention to solve the technical problems is: due to extraneous 8 core grid lines with after the network interface card interface is connected, only have 4 heart yearns to be connected with network card chip, the present invention respectively with in the 4 heart yearn parallel connections of using, connects network card chip by 4 heart yearns of free time afterwards again.
The invention has the beneficial effects as follows, this 8 line network interface card processed has avoided a certain heart yearn loose contact can cause the situation of net card failure.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the circuit theory diagrams that common network interface card is connected with 8 core grid lines.In Fig. 1, the 1st, extraneous grid line, the 2nd, RJ45 network interface card interface, the 3rd, the network interface card isolating transformer, the 4th, network card chip, 8 core grid lines, with after the network interface card interface is connected, only have 4 heart yearns to be connected with network card chip by the network interface card isolating transformer.
Fig. 2 is the circuit theory diagrams that 8 new gauze cards are connected with 8 core grid lines.In Fig. 2, the 1st, extraneous grid line, the 2nd, RJ45 network interface card interface, the 3rd, the network interface card isolating transformer, the 4th, network card chip, 8 core grid lines are with after the network interface card interface is connected, 4 idle heart yearns and 4 busy heart yearn parallel connections, then be connected with network card chip by the network interface card isolating transformer.
Embodiment
As shown in Figure 2,4 idle heart yearns and 4 busy heart yearns directly weld in parallel getting final product to embodiment.
Claims (2)
1. the present invention's 8 gauze cards, 8 core grid lines are with after the network interface card interface is connected, and 4 idle heart yearns and 4 busy heart yearn parallel connections, then be connected with network card chip.It is characterized in that: a certain heart yearn of 8 core grid line disconnects, and does not affect network interface card work.
2. 8 gauze cards according to claim 1,4 idle heart yearns can be before entering the network interface card isolating transformer and 4 busy heart yearn parallel connections, then by the network interface card isolating transformer, with network card chip, is connected; In addition, 4 idle heart yearns also can be after entering the network interface card isolating transformer, then with 4 busy heart yearn parallel connections, finally with network card chip, be connected, in this case, 8 heart yearns are all by the network interface card isolating transformer, then 4 idle heart yearns and 4 busy heart yearn parallel connections, then connect network card chip.
