Some embodiments, the utility model provides a PCB board that net gape is compatible, refer to fig. 1, including hundred million network transformer interfaces 110, giga network transformer interface 120, net gape interface 130, hundred million network transformer interface 110 is used for connecting hundred million network transformers, and giga network transformer interface 120 is used for connecting giga network transformer, and net gape interface 130 is connected with hundred million network transformer interface 110, and net gape interface 130 is connected with giga network transformer interface 120, and net gape interface 130 is used for connecting net gape connector.

In a specific example, in an actual assembly production process, a PCB board for producing a router with a hundred mega interface and a PCB board for producing a gigabit interface are basically the same in connection relationship of components on the PCB boards, but the specific soldered components are different when soldering. Therefore, by arranging the hundreds of megabits of network transformer interfaces 110 and the giga of network transformer interfaces 120 on the same PCB and electrically connecting the hundreds of megabits of network transformer interfaces and the same gigabit of network interface interfaces 130 with the same PCB, the routers with hundreds of megabits of interfaces or the routers with giga of interfaces can be assembled by selecting different components to assemble the circuits of the PCBs when the routers are assembled and produced. In the production line equipment production process of reality, only need prepare the PCB board of a type, just can produce the router of two kinds of types, need not arrange different PCB materials according to the different output of different grade type router, make things convenient for management and control production, avoid the material surplus to cause the loss. In some other embodiments, the network transformer interface may also be used to connect other types of network transformers, such as gigabit network transformers.

In some embodiments, a hundred mega network transformer interface 110 is interleaved with a gigabit network transformer interface 120. Because only one type of network transformer can exist on the PCB during actual welding and assembling, after the welding and assembling process is finished, the interface of the other type of network transformer is in an idle state. Therefore, in order to reduce the size of the whole PCB board, the hundreds of megabytes of network transformer interfaces 110 and the gigabytes of network transformer interfaces 120 are arranged in a crossed manner, that is, the installation positions of two different network transformers are designed in an overlapped manner, and in the design of the crossed position, the same effect can be achieved only by ensuring that the connecting lines between the network transformers and other elements are not affected. The connecting line arrangement can be set arbitrarily according to the actual design. Through the cross design, the total area of the PCB is saved, and the material cost for producing the PCB is reduced. In some other embodiments, the hundreds of megabytes network transformer interface 110 and the gigabytes network transformer interface 120 may be separately provided in case of high requirements for transmission signal line layout.

In some embodiments, the number of portal interfaces 130 is provided in two sets for connecting two portal connectors. Fig. 1 includes a first network interface 131 and a second network interface 132, and correspondingly, in order to output two gigabit networks, because the gigabit network transformer chip used in this embodiment can only output one gigabit network, the gigabit network transformer interfaces 120 are also set as two sets, including a first gigabit network transformer interface 121 and a second gigabit network transformer interface 122, which are respectively connected to the first network interface 131 and the second network interface 132. The hundred million network transformer chip used in this embodiment can output two hundred million networks, so that the effect of outputting two hundred million networks can be achieved only by setting one hundred million network transformer interface 110. For a specific example, please refer to fig. 2 to 4 for specific connection relationships between the pins. In fig. 2, J1 shows two sets of the net-port interfaces 130, which include 8 connection pins B1 to B8 of the first net-

port interface

131, and 8 connection pins a1 to a8 of the second net-port interface 132. In fig. 3, T1 and T2 are two same gigabit network transformers, and pin 12 to pin 15 and pin 17 to pin 20 on the right side of the gigabit network transformer T1 are output ports thereof for connecting pins B1 to B8 in the first network port interface 131, and pin 1 to pin 4 and pin 6 to pin 9 on the left side are input ports for connecting a switch chip in a router and receiving signals of the switch chip. The connection relationship of the gigabit network transformer T2 is the same as that of the gigabit network transformer T1, and is not described herein any more, and the connection manner of the network transformer and the switch chip is well known to those skilled in the art. Fig. 4 is a connection relationship diagram of one hundred mega network transformer T3 connected to two sets of network port interfaces 130, and pin 20, pin 19, pin 17, and pin 16 in the output port on the right side of the network transformer T3 are connected to B6, B3, B2, and B1 interfaces of the first network port interface 131, respectively. The pin 15, the pin 14, the pin 12, and the pin 11 of the network transformer T3 are respectively connected to the a6, A3, a2, and a1 interfaces of the second network port interface 132. The left input interface of the network transformer T3 is correspondingly connected to the input interfaces of the network transformer T1 and the network transformer T2, so that the hundreds of megabytes of network transformer 110 and gigabytes of network transformer 120 are electrically connected by a short connection line during the cross design. The connection relationship of other pins of the network transformer interface can be accurately obtained from the figure by those skilled in the art, and is not described in detail herein. By setting two sets of network interface 130, the router can extend two sets of local area networks in a wired manner, in some other embodiments, any number of sets of network interface 130 can be set according to design requirements, and the specific output and connection relation of the network transformer pins can be set arbitrarily according to the use method of the network transformer chip.

In some embodiments, the network port interface 130 includes 8 connection ports for connecting RJ45 network port connectors. The RJ45 network interface connector is composed of a plug and a socket, and the network interface 130 in this embodiment is specifically an interface for connecting an RJ45 socket, and can be connected with other devices by using a network cable with a standard crystal plug to complete a signal exchange function. RJ45 is the most popular network connector used at present, and can meet the use requirements of most users. Referring to fig. 1, the first network port interface 131 includes 8 ports B1 to B8, four ports of the hundreds mega network transformer need to be connected, and all 8 ports of the giga network transformer need to be connected, so as to increase the signal transmission rate.
