However, in practical applications, the design of flexible PINs is a significant factor affecting network interface performance. Existing network interface designs often struggle to ensure stable high-frequency signal transmission while also avoiding a large footprint. Utility Model Content

[0003] The purpose of the utility model is to provide a network interface, aiming to improve the stability of data transmission of the network interface.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] A network interface comprises an interface housing, wherein the interface housing is provided with a slot for connecting an adapter plug;

[0006] A seesaw spring is provided in the slot, the seesaw spring comprising a mounting portion and a spring portion arranged at an angle to each other, the mounting portion being connected to the interface housing, and the spring portion being elastically deformed toward the inner wall of the slot under the action of an external force;

[0007] The spring portion is provided with a flexible circuit board, and the flexible circuit board has a plurality of metal contacts, and the plurality of metal contacts are used for signal connection with the adapter plug.

[0008] In one embodiment, the bottom wall of the slot is further configured with a mounting guide groove, and the mounting portion is plugged into and engaged with the mounting guide groove.

[0009] In one embodiment, the network interface further comprises a PCB board, and the flexible printed circuit board is signal-connected to the PCB board;

[0010] The PCB board is mounted with filter components.

[0011] In one embodiment, the PCB board is further provided with a transformer.

[0012] In one embodiment, the network interface further comprises a dust cover;

[0013] The dust cover is provided with an electrostatic adsorption brush. When the dust cover is closed on the interface housing, the electrostatic adsorption brush contacts the metal contact.

[0014] In one embodiment, the dust cover is made of conductive rubber; the dust cover is further provided with a positioning piece, and the interface housing is further provided with an adapting groove adapted to the positioning piece for fixing the dust cover.

[0015] In one embodiment, a grounding conductive sheet is disposed in the adapting slot, and the positioning member is electrically connected to the grounding conductive sheet.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the technical solution of the present invention, a seesaw spring and a flexible circuit board are provided to replace the elastic PIN pins in traditional network interfaces. Compared to traditional elastic PIN pins, which occupy a large space and have low electromagnetic compatibility and poor heat dissipation performance, the present technical solution uses a flexible circuit board, which is placed in the spring portion of the seesaw spring. Because the flexible circuit board can bend and fold, it can better adapt to limited structural design space and reduce the space occupied by the network interface.

They also make it easier to add shielding layers to flexible printed circuits, improving the electromagnetic compatibility of network interfaces. Flexible printed circuits are also less prone to breakage or fatigue, whereas metal pins can experience elastic fatigue or breakage after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0029] An embodiment of the utility model provides a network interface.

[0030] See also Figure 1 、 Figure 2 and Figure 4In one embodiment of the present invention, the network interface 100 includes an interface housing 110 , wherein the interface housing 110 is provided with a slot 110 a , and the slot 110 a is used to connect an adapter plug;

[0031] A rocker spring 120 is disposed in the slot 110a. The rocker spring 120 includes a mounting portion 121 and a spring portion 122 that are arranged at an angle to each other. The mounting portion 121 is connected to the interface housing 110. The spring portion 122 elastically deforms toward the inner wall of the slot 110a under the action of an external force.

[0032] The elastic member 122 is provided with a flexible circuit board 130 . The flexible circuit board 130 has a plurality of metal contacts 131 . The plurality of metal contacts 131 are used for signal connection with the adapter plug.

[0033] It is understandable that in the technical solution of the present invention, a seesaw spring 120 and a flexible circuit board 130 are provided to replace the elastic PIN pin in the traditional network interface 100. Compared with the traditional elastic PIN pin, which occupies a large space and volume, has low electromagnetic compatibility and poor heat dissipation performance. The technical solution of the present invention uses a flexible circuit board 130, which is provided on the spring portion 122 of the seesaw spring 120. Since the flexible circuit board 130 can be bent and folded, it can better adapt to the limited structural design space and reduce the space occupied by the network interface 100. Furthermore, providing the flexible circuit board 130 on the spring portion 122 of the seesaw spring 120 can improve the reliability of the connection between the adapter plug and the metal contact 131 of the flexible circuit board 130, thereby improving the stability of data transmission.

[0034] Furthermore, during high-speed data transmission, the flexible circuit board 130 has a larger surface area than traditional elastic PIN pins, providing better heat dissipation and contributing to more stable data transmission. This also makes it easier to add a shielding layer to the flexible circuit board 130, improving the electromagnetic compatibility of the network interface 100. Furthermore, the flexible circuit board 130 is less prone to breakage or fatigue, whereas metal PIN pins may experience elastic fatigue or breakage after long-term use.

[0035] See also Figure 2 In a specific embodiment of the present invention, in order to fix the elastic seesaw, the bottom wall of the slot 110a is further configured with a mounting guide groove 110b, and the mounting portion 121 is plugged into and matched with the mounting guide groove 110b.

[0038] Optionally, the mounting portion 121 of the elastic seesaw and the elastic piece portion 122 are arranged at an acute angle.

[0041] The PCB board 140 is mounted with filter components 141 .

[0042] It is understandable that the network interface 100 is provided with a filter component 141 , and the filter component 141 can improve the electromagnetic compatibility of the network interface 100 , thereby further improving the stability of data transmission.

[0043] Optionally, the filtering component 141 may be an inductor or a capacitor.

[0044] Optionally, to meet higher performance requirements, the PCB board 140 is further provided with a transformer 142. It is understood that the designer of the transformer 142 can protect the circuit, prevent electrostatic discharge from damaging the device, reduce electromagnetic interference, and improve system reliability.

[0045] See also Figure 1 、 Figure 3 In a preferred embodiment, the network interface 100 further includes a dust cover 150;

[0046] The dust cover 150 is provided with an electrostatic adsorption brush 151 . When the dust cover 150 is closed on the interface housing 110 , the electrostatic adsorption brush 151 contacts the metal contact 131 .

[0047] It is understood that the dust cover 150 can prevent dust from entering the slot 110a, which could affect the stability of the data connection. The dust cover 150 is equipped with an electrostatic adsorption brush 151, which can contact the metal contacts 131 to release static electricity, thus preventing static electricity from accumulating on the flexible circuit board 130 and damaging the connected device.

[0048] Furthermore, if Figure 1As shown, the dust cover 150 is made of conductive rubber; the dust cover 150 is further provided with a positioning member 152 , and the interface housing 110 is further provided with an adapting groove 110 c adapted to the positioning member 152 for fixing the dust cover 150 .
