[0037] Reference Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the Ethernet interface module of an embodiment of the present application. Figure 2 This is a structural diagram of the Ethernet interface module from another angle according to an embodiment of the present application. Figure 3This is a schematic diagram of an Ethernet interface module according to an embodiment of the present application. The first embodiment of the present application provides an Ethernet interface module, comprising a substrate 100, a network interface connector 200, a network transformer 300, a chip 400, and a shielding cover 500. The end surface of the substrate 100 is provided with a first protrusion 110 and a second protrusion 120 at intervals, and a first recess 150 is formed between the first protrusion 110 and the second protrusion 120. The network interface connector 200 is mounted in the first recess 150. The network transformer 300 is mounted in the first recess 150, and the network transformer 300 is located on one side of the network interface connector 200. The chip 400 is provided on the bottom surface of the substrate 100, and the first protrusion 110, the second protrusion 120, the network interface connector 200, and the network transformer 300 are all located in the shielding cover 500, which is used to shield external electromagnetic signals.

[0038] The Ethernet interface module of the present embodiment integrates the network interface, network transformer 300, and chip 400 onto substrate 100, facilitating device miniaturization. Furthermore, the first and second protrusions 110, 120 protect the network interface connector 200 and the network transformer 300. The shielding cover 500 shields external electromagnetic signals, reducing electromagnetic interference from external electromagnetic signals on the network interface connector 200 and the network transformer 300, thereby improving the Ethernet interface module's ability to resist electromagnetic interference.

[0039] It is worth noting that the network interface connector 200 is a physical interface device used to connect a computer to a network, or between network devices. It plays a crucial role in network communications, enabling the conversion and transmission of digital data and analog signals. In one embodiment, the network interface connector 200 utilizes an RJ45 connector, a standardized eight-core cable plug commonly used to connect computers, switches, routers, and other network devices to implement Ethernet communications.

[0040] In one embodiment, the first and second protrusions 110, 120 are ceramic, and are covered with a copper metal layer. This allows the first and second protrusions 110, 120 to shield electromagnetic signals, thereby reducing interference from external electromagnetic signals to the network interface connector 200 and network transformer 300 located within the first recess 150. The multiple shielding effects of the first and second protrusions 110, 120, and shielding cover 500 provide the Ethernet interface module of this embodiment with a high degree of resistance to electromagnetic interference.

[0041] In one embodiment, the shielding cover 500 is made of metal, such as copper or stainless steel, so that the shielding cover 500 can shield external electromagnetic signals.

[0042] In one embodiment, referring to Figure 3 The bottom surface of the substrate 100 is provided with a third protrusion 130 and a fourth protrusion 140, with a second recess 160 formed between the third protrusion 130 and the fourth protrusion 140. The chip 400 is disposed in the second recess 160. Since the chip 400 is disposed in the second recess 160, when the bottom surface of the substrate 100 is mounted on a circuit board or a printed circuit board, the chip 400 is not squeezed, and the second recess 160 facilitates heat dissipation of the chip 400.

[0043] In one embodiment, a capacitor and a resistor are further included. Both the capacitor and the resistor are disposed on the bottom surface of the substrate 100 , and both are located in the second recess 160 .

[0044] In one embodiment, the substrate 100 is a ceramic substrate 100 , which is beneficial for heat dissipation of the chip 400 .

[0045] In one embodiment, referring to Figure 3 The shielding cover 500 defines a first opening 510 , which is opposite to the first recess 150 . The network interface connector 200 is located on a side of the first recess 150 close to the first opening 510 .

[0046] It should be noted that the network interface connector 200 needs to be connected to an external device. In the present application, the shielding cover 500 is provided with a first opening 510, which is opposite to the first recess 150. The network interface connector 200 is located on the side of the first recess 150 close to the first opening 510. In this way, the plug of the external device can pass through the first opening 510 and be inserted into the slot of the network interface connector 200, so as to facilitate electrical connection between the network interface connector 200 and the external device.

[0047] In one embodiment, referring to Figure 2 and Figure 3 The bottom of the shielding cover 500 is provided with a second opening. The bottom of the shielding cover 500 is provided with an abutting member 530 . The abutting member 530 is provided at the edge of the second opening, and the abutting member 530 abuts against the second recess 160 .

[0048] Specifically, two opposing sides of the shielding cover 500 are provided with abutment members 530, which are perpendicular to the sides of the shielding cover 500. The abutment members 530 abut against the second recess 160, thereby securing the shielding cover 500 relative to the substrate 100. It is worth noting that the shape of the shielding cover 500 matches that of the substrate 100, and the abutment members 530 are provided at the edge of the second opening at the bottom of the shielding cover 500. The shielding cover 500 covers the end faces and side faces of the substrate 100, but does not cover the bottom face of the substrate 100.

[0049] Specifically, the number of the abutting members 530 is four, wherein two abutting members 530 are disposed on one side surface of the shielding cover 500 , and the other two abutting members 530 are disposed on the other opposite side surface of the shielding cover 500 .

[0050] In one embodiment, a spring piece 520 is disposed on a side surface of the shielding cover 500 , and one end of the spring piece 520 is disposed in the first opening 510 , while the other end of the spring piece 520 passes through the first opening 510 .

[0051] It should be noted that the number of spring clips 520 is two, and the two spring clips 520 are respectively arranged on opposite sides of the first opening 510. When the plug of the external device is inserted into the slot of the network interface connector 200 from the first opening 510, the plug of the external device squeezes the spring clip 520. Since the force is mutual, the spring clip 520 generates pressure on the plug of the external device. Therefore, the two spring clips 520 can clamp the plug and stabilize the connection between the plug and the slot.

[0052] In one embodiment, referring to Figure 4 , Figure 4 2 is a schematic structural diagram of the network interface connector 200. The inner side wall of the slot of the network interface connector 200 is provided with a groove 210 that matches the spring 520.

[0053] Specifically, grooves 210 matching the spring piece 520 are respectively provided on opposite sides of the slot of the network connector. When the plug of the external device is inserted into the slot of the network interface connector 200 from the first opening 510, the plug of the external device squeezes the spring piece 520. Under the squeezing action of the plug, the spring piece 520 is squeezed into the groove 210 corresponding to the slot of the network interface connector 200, so that the spring piece 520 can clamp the plug of the external device without hindering the connection between the external plug and the slot.

[0054] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features of the embodiments can be combined with each other unless there is a conflict.
