In the scheme, based on the design of the mature Ethernet interface circuit owned by the electronic equipment, the core components for realizing network data transmission are integrated into the network interface component, so that the network interface component with stable performance is provided, and the design cost for independently designing the Ethernet interface circuit by an electronic equipment manufacturing enterprise can be effectively reduced; and through standardized network interface assembly, can reduce the material supply complexity of electronic equipment manufacturing enterprise to reduce ethernet interface circuit's manufacturing cost.

In electronic equipment manufacturing industries such as network equipment manufacturing industry, computer PC manufacturers, network printer design manufacturers, network system security architecture industry and the like, a large number of enterprises provide professional electronic equipment for various application scenes of the small and numerous people, and the electronic equipment is usually professional. For such enterprises, products with high function matching degree can be provided in the application field, but for the underlying software and hardware design, for example, the related software and hardware design of the ethernet interface circuit is relatively short board, the integrated network interface component in the scheme is realized based on the existing ethernet interface circuit design, so that the investment of such enterprises on basic function software and hardware development can be reduced, the development of the application field matching function is concentrated, the development cost of such enterprises is reduced on the whole, the development period is shortened, and the stability of the basic software and hardware functions of the finally designed products and the consistency of the products are ensured.

For electronic products with high specialty, the order of magnitude of the market is far less than that of consumer electronic products, and the types of components required by the electronic equipment are not few, for this kind of enterprises, the relatively small market demands the number and the few components, so that the supply chain is relatively complex when producing the products, the stability of the supply chain cannot be guaranteed through the huge number, and the cost of the supply chain cannot be spread. Particularly, in the case that the whole chip manufacturing industry may suspend production and supply interruption at any time due to external reasons, such enterprises may not guarantee normal production, and the overall supply guarantee capability of the enterprises is weak.

When the original supply chain is interrupted, one processing way of the related manufacturing enterprises is to additionally search suppliers of the same kind or the same type of chips, continue to use the original design or fine-tune the original design to continue the production, but the process of searching for a new supplier is uncertain. In another processing mode, a core component is additionally found to design the ethernet interface circuit, but the redesign of the ethernet interface circuit is not performed after the core component is replaced, but the entire circuit needs to be completely updated and redesigned, and the design work is not a good development direction of related production enterprises generally. Either way, this will bring up the cost of the entire supply chain.

On the contrary, the production enterprise integrating the network interface component based on the scheme can integrate a plurality of enterprises with small demand for related components of the Ethernet interface circuit into an enterprise with huge demand, so that a stable supply chain is formed by relying on the huge demand, the integrated network interface component with stability and low cost is provided, and the design cost and the production cost can be effectively reduced for the enterprises producing electronic equipment with high professional degree.

In addition to the optimization of the effect of the supply chain, the network transformer 131, the PHY chip 132, the crystal oscillator 133, the peripheral circuit and the seat are all packaged together in the scheme, so that the space on the circuit board can be effectively saved. First casing 11 adopts the metal shielding shell, can effectively improve the interference killing feature to can not produce the interference to the components and parts on the circuit board. The packaged integrated network interface component 10 can be designed in a manner of being compatible with the pins and the structural dimensions of the hundred-million RJ45 socket and the gigabit RJ45 socket, so that the upgrading design of a network port is facilitated, and the overall cost is reduced.

When the interface for implementing a tera network is implemented, that is, when the network transformer 131 is a tera network transformer, the network transformer 131 is mounted on the outer board surface of the first circuit board 141, the second board surface of the substrate 122 is provided with two bosses, and the network transformer 131 is accommodated in a cavity defined by the second board surface of the substrate 122, the two bosses, and the outer board surface of the first circuit board 141. The boss is integrally formed with the substrate 122, and the network transformer 131 is held at a distance from the substrate when being accommodated in the enclosed cavity.

In a specific implementation of the integrated network interface assembly 10 of this embodiment, the crystal oscillator 133 is mounted on the inner board surface of the second circuit board, and the PHY chip 132 is mounted on the outer board surface of the second circuit board 143.

Of course, the crystal oscillator 133 and the PHY chip 132 may be mounted on the same board or on the same board in an interchangeable manner.

The connection line in this embodiment is provided inside the connection plate 142. This arrangement makes it possible to complete circuit connection of the first circuit board 141, the connection plate 142, and the second circuit board 143 to one upon assembly. Of course, the first circuit board 141 and the second circuit board 143 need to reserve corresponding holes for implementing electrical connection corresponding to the connection lines, which is a general technique for circuit board connection and is not described herein.

When the connection of the connection pins 162 is embodied, the connection pins 162 are connected to the first circuit board 141 through a boss.

The connection pins are connected to the first circuit board 141 by the bosses, which effectively enhances the connection firmness of the connection pins 162.

The first circuit board 141, the connection plate 142, and the second circuit board 143 are connected to form a U-shaped structure, which is entirely accommodated in the second housing 12 and has an opening facing the cable connection port.

The integrated network interface component 10 in the present embodiment may further include a network connection indicator 151 and a data transmission indicator 152;

the network connection indicator 151 and the data transmission indicator 152 are both mounted on the second circuit board 143, and the first housing 11 and the second housing 12 are both provided with light outlets corresponding to the network connection indicator 151 and the data transmission indicator 152. The network connection indicator light 151 and the data transmission indicator light 152 may identify the network connection status and the data transmission status of the integrated network interface component or even the entire electronic device.

The layout of the metal elastic sheet 161 is determined according to the type of the designed network interface of the integrated network interface component 10, in the scheme shown in the drawing, the metal elastic sheet 161 is a metal elastic sheet of an RJ45 interface, and if the metal elastic sheet is a network interface of other types, the layout of the metal elastic sheet 161 is adjusted correspondingly. Of course, the specific chip and the corresponding peripheral circuit also need to be adjusted according to the corresponding interface type.

Further referring to fig. 9 and 10, the integrated network interface component 10 in this embodiment may be used for gigabit network data transmission, in addition to hundred megabytes of network data transmission, that is, the network transformer 131 is a gigabit network transformer, which is larger than a hundred megabytes of network transformers, and the PHY chip 132 in the gigabit integrated network interface component 10 has a heat dissipation requirement, in order to control the size of the integrated network interface component 10 and ensure a heat dissipation effect, as shown in fig. 9 and 10, the network transformer 131 is mounted on the inner board surface of the first circuit board 141, that is, the network transformer 131 is entirely located inside the U-shaped structure and keeps a distance from the second circuit board 143. The other structures and layouts of the gigabit integrated network interface component and the hundred megabyte integrated network interface component are substantially the same, and the description thereof is not repeated here. Of course, in a specific implementation process, based on the architectures of fig. 9 and fig. 10, a hundred million network transformer may also be implemented, and for a giga network transformer, a hundred million network transmission may also be compatibly implemented.

When the circuit design is performed based on the integrated network interface component 10 in this solution, as shown in fig. 11, it is only necessary to complete the routing of the MAC controller of the MCU20 and the connection pins 162, and it is not necessary to process the layout design of the peripheral circuits of the PHY chip 132 and the network transformer 131. Compared with the prior art in fig. 12 that needs to deal with the design of the MCU20, the PHY chip 132 ', the network transformer 131', and various peripheral circuits, the integrated network interface component in this solution greatly simplifies the hardware design content of each manufacturing enterprise.
