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
Technical field [0001] The invention relates to a network adapter with an RJ-45 interface for computer networking, which is commonly referred to as a network card. Background technique [0002] At present, the most widely known RJ-45 interface network card is made up of a network card chip and a network card isolation transformer. There are 8 cores in the external network cable, but only 4 cores are connected to the network card chip. The other 4 cores are originally reserved for telephone lines, but in fact, almost no network cables connected to the LAN are used to connect the phone at the same time, that is to say, the other 4 cores The core wire is completely free. In addition, as everyone knows, the use of twisted-pair wires in the network can prevent signal crosstalk, but practice has proved that the computer can work normally with the new network card of the present invention, that is to say, the present invention is completely reasonable.
