Description

Technical Field

[0001] This utility model relates to the field of network equipment technology, and in particular to a network port module. Background Technology

[0002] In the field of network communication, network port modules are widely used in network devices such as computers, switches, and routers, serving to connect networks and transmit data. One end of the network port module connects to the internal circuitry or motherboard of the device, while the other end connects to external network devices or transmission media. However, currently available network port modules have some limitations, making it difficult to simultaneously meet requirements for grounding performance, compact size, and ease of installation.

[0003] Currently, there are two main types of network port modules commonly found on the market: rectangular metal network port modules and circular non-metal network port modules. Rectangular metal network port modules have a thick metal layer surrounding the insulating block, which effectively enables grounding and ensures the stability of signal transmission. However, they are bulky, expensive, and can only be fitted with rectangular housings, not circular housings, resulting in limited installation space and making it difficult to meet diverse installation needs.

[0004] On the other hand, although the circular non-metallic network port module can be connected to the housing with the circular hole, its material is entirely non-metallic, which cannot achieve grounding and conduction, and cannot guarantee the stability of signal transmission, thus failing to meet the actual use requirements.

[0005] In conclusion, how to effectively resolve the contradiction between the grounding function of traditional network port modules and actual installation requirements has become an urgent problem for those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a network port module that can both achieve grounding function to ensure stable signal transmission and meet actual installation requirements.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A network port module includes a module body, an elastic support frame, and a metal flange housing. The module body includes an insulating block and a metal sheet surrounding the outer periphery of the insulating block. At least one side of the insulating block has a groove communicating with both sides thereon. The metal sheet extends at the side of the groove to form a limiting piece. The elastic support frame is installed in the groove to support the limiting piece. The elastic support frame has a limiting part for limiting. The metal flange housing has an inner hole along the axial direction and a limiting hole on the side wall. After the elastic support frame is installed in the groove, the entire module is pressed into the inner hole, so that the limiting part is inserted into the limiting hole and the limiting piece contacts the inner wall of the metal flange housing. The metal flange housing is connected to the mounting hole of the housing.

[0009] Optionally, the limiting part is a boss provided on the surface of the elastic support frame. After the elastic support frame is installed in the groove, the surface of the elastic support frame is flush with the surface of the module body and the boss protrudes from the surface of the module body.

[0010] Optionally, the boss is provided with a guide slope at one end where it is inserted into the inner hole. The guide slope starts from a diameter position perpendicular to the axis of the inner hole and gradually slopes downwards towards the insertion point along the axis of the inner hole.

[0011] Optionally, the elastic support frame includes a bracket and a support foot located at the corner of the bracket. The groove includes a receiving groove adapted to the bracket and a limiting groove adapted to the support foot. During installation, the support foot is embedded in the limiting groove, the bracket is embedded in the receiving groove, and a limiting piece is provided on the outside of the limiting groove. The width of the limiting groove is smaller than the width of the support foot.

[0012] Optionally, the bottom surface of the bracket is provided with a recessed groove opposite to the receiving groove, the bottom surface of the recessed groove is spaced from the surface of the column in the receiving groove, the bottom surface of the support foot contacts the bottom surface of the limiting groove, and the receiving groove and the recessed groove are configured to provide clearance space for the elastic deformation of the boss when the elastic support frame is pressed into the inner hole.

[0013] Optionally, the limiting piece is located at the position of the limiting groove, the limiting piece is in contact with the outer wall of the support foot, and the two ends of the limiting piece form a spacer groove.

[0014] Optionally, the upper end of the limiting piece is bent inward to form a locking piece, which presses against the surface of the elastic support frame.

[0015] Optionally, the outer wall of the support foot forms a gradually expanding arc surface from the root to the end, the limiting piece contacts the arc surface of the support foot, and the limiting groove reserves clearance space at the end of the support foot to provide elastic deformation of the support foot length.

[0016] Optionally, the elastic support frame is made of nylon, the support includes an outer frame and a cross connected to the outer frame, the boss is located at the center of the cross, and the elastic support frame is integrally formed.

[0017] Optionally, the metal sheet covers the bottom surface and two sides of the module body, and the thickness of the metal sheet is 0.2mm-0.4mm.

[0018] The beneficial effects of this utility model are as follows: the network port module provided by this utility model has an insulator block with a groove on at least one side, and an elastic support frame is installed in the groove. The metal flange shell has an inner hole along the axial direction to accommodate the module body and the elastic support frame. When the elastic support frame is installed in the groove, the limiting plate is opened by the elastic support frame. Subsequently, the elastic support frame and the module body are pressed together into the inner hole of the metal flange shell. Through the elastic deformation of the elastic support frame, the limiting plate can be opened to an appropriate position and make tight contact with the inner wall of the metal flange shell, thereby realizing the grounding function. After installation, the limiting plate of the network port module will form an interference contact with the metal flange shell to ensure the realization of the grounding function, thereby ensuring the stability of signal transmission.

[0019] The flexible support frame also features a limiting part, with limiting holes on the side wall of the metal flange housing. When the module is press-fitted into the inner hole, the limiting part of the flexible support frame can precisely insert into the limiting hole of the metal flange housing, achieving the functions of fixing and limiting the flexible support frame to the metal flange housing. The module body can be naturally fixed inside the metal flange housing, ensuring that it will not loosen or shift during use.

[0020] The metal flange housing also features a structure adapted to the mounting holes of the outer housing, connecting the network module to the outer housing to achieve reliable network connectivity. The shape and size of the mounting holes on the metal flange housing are adapted to the shape and size of the mounting holes on the outer housing. For example, when the connecting end of the metal flange housing is cylindrical, it can be connected to an outer housing with round mounting holes, thereby fixing the rectangular network module to the housing with round mounting holes. This allows for diverse connection options for the network module and further expands its applicability.

[0021] The network module provided by this utility model achieves grounding through the contact between the limiting plate and the metal flange shell, effectively guiding the electromagnetic interference and static electricity generated by the module to the grounding system, ensuring the stability of signal transmission and the safety of the equipment. The elastic support frame and the limiting hole cooperate to fix the module, making the installation process simple, quick, and secure, reducing installation time and cost. The overall design has a small size, meeting the needs of compact installation, while ensuring functionality and reliability. Attached Figure Description

[0034] The core of this utility model is to provide a network port module that can both achieve grounding function to ensure stable signal transmission and meet actual installation requirements.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please refer to Figures 1 to 9 , Figure 1 This is a schematic diagram of a network port module provided in a specific embodiment of the present invention; Figure 2 for Figure 1 Schematic diagram of the structure of the medium elastic support frame 2; Figure 3 for Figure 1 A schematic diagram of the structure of module 1; Figure 4 for Figure 1 Schematic diagram of the structure of the metal flange housing 3; Figure 5 This is a schematic diagram showing the connection between the elastic support frame 2 and the module body 1; Figure 6 This is a side view showing the connection between the elastic support frame 2 and the module body 1; Figure 7 This is a schematic diagram showing the connection between the elastic support frame 2, the module body 1, and the metal flange shell 3. Figure 8 A side view showing the connection between the elastic support frame 2, the module body 1, and the metal flange housing 3; Figure 9 This is an overall schematic diagram of the elastic support frame 2, the module body 1, and the metal flange shell 3.

[0037] In one specific embodiment, the network module provided by this utility model includes a module body 1, an elastic support frame 2, and a metal flange shell 3. The module body 1 includes an insulating block and a metal sheet wrapped around the outer periphery of the insulating block. At least one side of the insulating block is provided with a groove 11 communicating with both sides thereon. The metal sheet extends at the side of the groove 11 to form a limiting piece 12. The elastic support frame 2 is installed in the groove 11 to support the limiting piece 12. The elastic support frame 2 is provided with a limiting part for limiting. The metal flange shell 3 is provided with an inner hole 32 along the axial direction and a limiting hole 31 provided on the side wall. After the elastic support frame 2 is installed in the groove 11, the entire module is pressed into the inner hole 32, so that the limiting part is inserted into the limiting hole 31 and the limiting piece 12 contacts the inner wall of the metal flange shell 3. The metal flange shell 3 is connected to the mounting hole of the shell.

[0038] In the above structure, the insulator block can be made of insulating materials such as nylon, plastic, or ceramic, which can effectively prevent abnormal current conduction inside the network port module, thereby ensuring the safety and reliability of the network port module. A metal sheet wraps around the outer perimeter of the insulator block, serving as grounding and shielding. It can conduct electromagnetic interference or static electricity generated by the module body 1 to the grounding system, avoiding interference with signal transmission, thus ensuring the stability of signal transmission and the safety of the equipment.

[0039] The metal flange housing 3 has an inner hole 32 along the axial direction. The shape and size of the inner hole 32 match the module body 1 to accommodate the module body 1 and the elastic support frame 2. The inner wall of the inner hole 32 serves to support and position the module body 1, ensuring that the module can be stably fixed therein after installation. For example, when the insulating block is the insulating block of a rectangular network port module currently on the market, the shape of the inner hole 32 is designed to be rectangular or nearly rectangular in order to accurately accommodate the entire network port module.

[0040] The insulating block has a groove 11 on at least one side, extending to both sides of the insulating block. The groove 11 provides an installation position for the elastic support frame 2, and its shape and size allow for the positioning and fixing of the elastic support frame 2. The number of grooves 11 depends on the specific structure and installation requirements of the module body 1, and is generally one or more, distributed on different side walls of the insulating block. A metal sheet extends from the side of the groove 11 to form a limiting piece 12. The limiting piece 12 is part of the metal sheet and can cooperate with the elastic support frame 2 and the metal flange housing 3 to achieve the fixing and limiting functions of the module body 1.

[0041] The elastic support frame 2 can be made of nylon or special elastic plastics, which not only have good elasticity but also sufficient strength. Located between the insulating block and the metal flange housing 3, the elastic support frame 2's structure considers the range and stability of elastic deformation to ensure reliable expansion of the limiting plate 12 and reliable connection with the metal flange housing 3 during installation and use, while maintaining a stable limiting function to guarantee reliable connection and support.

[0042] When the elastic support frame 2 is installed in the groove 11, the limiting piece 12 will be expanded by the elastic support frame 2. Subsequently, the elastic support frame 2 and the module body 1 are pressed together into the inner hole 32 of the metal flange housing 3. Through the elastic deformation of the elastic support frame 2, the limiting piece 12 can be expanded to the appropriate position and make tight contact with the inner wall of the metal flange housing 3, thereby realizing the grounding function. After installation, the limiting piece 12 of the network module will form an interference contact with the metal flange housing 3 to ensure the grounding function and thus ensure the stability of signal transmission.

[0043] The elastic support frame 2 is also equipped with a limiting part, and the side wall of the metal flange housing 3 is provided with a limiting hole 31. The position, shape, and size of the limiting part correspond precisely to the limiting hole 31. When the module is pressed into the inner hole 32, the limiting part of the elastic support frame 2 can be accurately inserted into the limiting hole 31 of the metal flange housing 3, realizing the fixing and limiting functions of the elastic support frame 2 and the metal flange housing 3. The shape and size of the limiting hole 31 match the limiting part, ensuring that the limiting part can be accurately inserted into the limiting hole 31, and after installation, the limiting part can maintain a stable state and will not easily loosen or fall off. The module body 1 can be naturally fixed in the metal flange housing 3, ensuring that there will be no loosening or displacement during use. This design can adapt to metal flange housings 3 of different sizes and shapes, and has strong versatility and adaptability.

[0044] The metal flange housing 3 also features a structure adapted to the mounting holes of the outer housing, connecting the network port module to the outer housing (such as the panel of a network device or the enclosure of other mounting components) to achieve reliable network connectivity. The connection end of the metal flange housing 3 is adapted to the shape and size of the mounting holes of the outer housing. For example, when the connection end of the metal flange housing 3 is cylindrical, it can be connected to an outer housing with round mounting holes, thereby fixing the rectangular network port module to the housing with round mounting holes, enabling diverse connection options for the network port module and further expanding the applicability of the rectangular network port module.

[0045] During assembly, firstly, the elastic support frame 2 is installed in the groove 11 on the side of the insulator block. At this time, the limiting part of the elastic support frame 2 is in the state of being inserted into the limiting hole 31.

[0046] Then, the entire module body 1 and the elastic support frame 2 are press-fitted into the inner hole 32 of the metal flange housing 3. During the press-fitting process, the elasticity of the elastic support frame 2 will cause the limiting piece 12 to open and contact the inner wall of the metal flange housing 3, thereby achieving grounding and conduction.

[0047] At the same time, when the module is fully press-fitted into place, the limiting part of the elastic support frame 2 is inserted into the limiting hole 31 on the side wall of the metal flange housing 3, thus completing the fixing and limiting of the module.

[0048] Finally, the network module is installed onto other devices or components by connecting the metal flange housing 3 to the mounting holes of the housing, thus completing the entire assembly process.

[0049] The network module provided by this utility model achieves grounding through the contact between the limiting piece 12 and the metal flange shell 3, effectively guiding the electromagnetic interference and static electricity generated by the module to the grounding system, ensuring the stability of signal transmission and the safety of the equipment. The elastic support frame 2 cooperates with the limiting hole 31 to fix the module, making the installation process simple, quick, and secure, reducing installation time and cost. The overall design has a small size, meeting the requirements of compact installation, while ensuring functionality and reliability.

[0050] Based on the above specific embodiments, the limiting part is a boss 21 provided on the surface of the elastic support frame 2. After the elastic support frame 2 is installed in the groove 11, the surface of the elastic support frame 2 is flush with the surface of the module body 1 and the boss 21 protrudes from the surface of the module body 1.

[0051] In practical applications, the overall shape of the elastic support frame 2 matches the groove 11 on the side of the insulator block, allowing it to be tightly embedded. It is typically a sheet-like or frame-like structure with a certain degree of elastic deformation capability, enabling it to adapt to the size requirements of the module body 1 and the metal flange shell 3 during installation, while also accommodating certain installation errors, thereby further improving the convenience of installation.

[0052] The limiting part is a boss 21 structure on the surface of the elastic support frame 2. After installation, it protrudes from the surface of the module body 1, serving to limit and fix the module. The shape and size of the boss 21 match the limiting hole 31. Its height and width ensure smooth insertion into the limiting hole 31 and provide sufficient limiting force during module pressing to prevent the module from coming out of the limiting hole 31 due to vibration or external force, thus firmly fixing the module. The boss 21 can have various shapes, such as circular, square, or other shapes. Its position can be set in the middle of the elastic support frame 2 to distribute the force evenly, or located on the edge or side to align with the limiting hole 31.

[0053] During installation, the elastic support frame 2 is first placed into the groove 11. At this time, the elastic support frame 2 will undergo a certain elastic deformation to adapt to the shape and size of the groove 11. When the elastic support frame 2 is fully installed, its surface is flush with the surface of the module body 1, which means that the elastic support frame 2 is tightly fitted with the insulating block and metal sheet to form a stable overall structure.

[0054] After installation, the boss 21 protrudes from the surface of the module body 1, allowing it to smoothly insert into the limiting hole 31 when the module is pressed into the metal flange housing 3. When the entire module body 1 and the elastic support frame 2 are pressed into the inner hole 32 of the metal flange housing 3, the boss 21 of the elastic support frame 2 will precisely align with the limiting hole 31 on the side wall of the metal flange housing 3. As the module is pressed in, the elastic support frame 2 undergoes elastic deformation, and the boss 21 gradually inserts into the limiting hole 31. When the module is fully pressed in place, the boss 21 is fully inserted into the limiting hole 31, serving to fix and limit the movement. Simultaneously, the elastic deformation of the elastic support frame 2 will also open the limiting piece 12 on the metal sheet, ensuring close contact between the limiting piece 12 and the inner wall of the metal flange housing 3, thereby achieving grounding conductivity. At this point, the module is firmly fixed within the metal flange housing 3, ensuring its stability during use.

[0055] As described above, a boss 21 is provided on the surface of the elastic support frame 2 as a limiting part, giving it the dual functions of grounding and limiting: grounding is achieved by expanding the limiting piece 12, and limiting is achieved by the cooperation of the boss 21 and the limiting hole 31. This design not only reduces the number of parts but also simplifies the structure, facilitates manufacturing and installation, and effectively improves the overall performance and reliability of the module. The boss 21 protrudes from the surface of the module body 1, facilitating quick alignment of the limiting hole 31 during press-fitting, thereby significantly reducing installation time and difficulty.

[0056] Based on the above specific embodiments, the boss 21 is provided with a guide slope 22 at one end of its insertion into the inner hole 32. The guide slope 22 starts from a diameter position perpendicular to the axis of the inner hole 32, which is the highest point of the boss 21. Along the axis of the inner hole 32, that is, the direction in which the boss 21 is inserted, the guide slope 22 gradually slopes downward, forming a ramp-like structure. At the insertion point, the height of the guide slope 22 is minimal, ensuring that the boss 21 can smoothly enter the limiting hole 31.

[0057] During actual installation, when the module body 1 and the elastic support frame 2 are press-fitted into the inner hole 32 of the metal flange housing 3, the guide ramp 22 of the boss 21 will first contact the edge of the limiting hole 31. As the pressing proceeds, the guide ramp 22 gradually guides the boss 21 into the limiting hole 31, ultimately achieving a precise fit between the boss 21 and the limiting hole 31. This process not only improves the success rate of installation but also ensures the stability and reliability of the module during use.

[0058] During module press-fitting, the guide ramp 22 at the insertion end of the boss 21 guides the module into the inner hole 32 of the metal flange housing 3 and guides the boss 21 into the limiting hole 31, reducing friction and insertion resistance during press-fitting and ensuring precise insertion of the boss 21 into the limiting hole 31, thus improving installation efficiency and reliability. The gradually downward sloping structure of the guide ramp 22 makes the insertion process smoother, simplifies installation steps, reduces operational difficulty, and improves production efficiency. In addition, the guide ramp 22 can automatically correct installation errors, allowing for smooth insertion through the ramp, reducing insertion resistance, improving installation accuracy, avoiding damage to the module body 1 and the metal flange housing 3, extending service life, and providing reliable protection for module installation and use.

[0059] Based on the above specific embodiments, the elastic support frame 2 includes a bracket and a support foot 23 located at the corner of the bracket. The groove 11 includes a receiving groove adapted to the bracket and a limiting groove adapted to the support foot 23. During installation, the support foot 23 is embedded in the limiting groove, and the bracket is embedded in the receiving groove.

[0060] In practical applications, the elastic support frame 2 includes a bracket and support feet 23, and the groove 11 of the insulating block includes a receiving groove and a limiting groove. The bracket and support feet 23 are made of elastic and strong materials, which can withstand a certain deformation force during installation and return to a stable state after installation.

[0061] The receiving groove is located at the center of the groove 11 and can be rectangular or square in shape. The shape and size of the bracket are adapted to the receiving groove. The limiting groove is located at the edge of the receiving groove, and the support foot 23 is the protruding part at the corner of the bracket, corresponding to the position of the limiting groove. Preferably, the limiting groove is distributed at the four corners of the receiving groove, and the support foot 23 is distributed at the four corners of the bracket, thereby providing uniform support and limiting effect. During installation, align the bracket of the elastic support frame 2 with the receiving groove on the side of the insulator block to ensure that the bracket can be smoothly inserted. At the same time, align the support foot 23 with the limiting groove. After the bracket is inserted into the receiving groove, the two fit tightly and stably, while the bracket retains a certain elastic deformation in the receiving groove. After the support foot 23 is inserted into the limiting groove, the support foot 23 retains a certain elastic deformation in the limiting groove, thereby realizing the fixing function of the elastic support frame 2.

[0062] Meanwhile, a limiting piece 12 is provided on the outer side of the limiting groove. The limiting piece 12 is part of a metal sheet, and its shape and size are adapted to the limiting groove. It is usually rectangular or square and can cover the outer side of the limiting groove. The shape of the support foot 23 is adapted to the limiting groove, and the width of the limiting groove is smaller than the width of the support foot 23. When the elastic support frame 2 is installed in place, the support foot 23 will open the limiting piece 12 and make the limiting piece 12 protrude from the metal sheet, so that it contacts the inner wall of the metal flange shell 3, realizing grounding and improving the stability of signal transmission. At this time, the surface of the elastic support frame 2 is flush with the surface of the module body 1, the support foot 23 is embedded in the limiting groove, and the bracket is embedded in the receiving groove.

[0063] By embedding the bracket and support foot 23 of the elastic support frame 2 into the receiving groove and limiting groove of the insulating block respectively, the entire module has a compact structure that meets the requirements of miniaturization. When the support foot 23 opens the limiting piece 12, only a small elastic force is required, which is sensitive and has a fast response speed.

[0064] Based on the above specific embodiments, the bottom surface of the bracket is provided with a recessed groove opposite to the receiving groove. The bottom surface of the recessed groove is spaced from the surface of the column in the receiving groove. The bottom surface of the support leg 23 is in contact with the bottom surface of the limiting groove. The receiving groove and the recessed groove are configured to provide clearance space for the elastic deformation of the boss 21 when the elastic support frame 2 is pressed into the inner hole 32.

[0065] In practical applications, the receiving groove contains uprights, and the recessed groove is vertically opposite to the receiving groove. The recessed groove is a concave area on the bottom surface of the support frame, used to accommodate the uprights within the receiving groove. The area of ​​the recessed groove is larger than the area enclosed by all the uprights, and is usually rectangular or circular. The depth design of the recessed groove ensures both the strength of the support frame and that an appropriate gap is maintained between the surface of the uprights and the bottom surface of the recessed groove after the support frame is embedded in the receiving groove.

[0066] The recessed groove ensures a proper distance between the bracket and the column during installation, preventing interference from the column with the elastic deformation of the boss 21. This provides necessary clearance for the elastic deformation of the boss 21 during the press-fitting process, ensuring that the boss 21 can be smoothly pressed into the inner hole 32 and reach directly below the limiting hole 31, thus ensuring a smooth installation process. Simultaneously, the receiving groove provides ample clearance for the elastic deformation of the boss 21, allowing for greater flexibility and preventing installation failure or component damage due to obstructed deformation. This design improves installation reliability and success rate, and extends the service life of the components.

[0067] When the elastic support frame 2 is pressed into the inner hole 32 of the metal flange housing 3, and the boss 21 reaches directly below the limiting hole 31, the boss 21 on the support restores its elastic deformation and inserts into the limiting hole 31, thus completing the installation.

[0068] During installation, the bottom surface of the support foot 23 is in close contact with the bottom surface of the limiting groove, providing support and ensuring that the elastic support frame 2 can be stably embedded in the groove 11 and remain stable after installation. The contact area between the support foot 23 and the limiting groove is moderate, which not only allows the elastic support frame 2 to be firmly fixed in the groove 11, enhancing the stability of the overall structure and preventing the elastic support frame 2 from shifting or even popping out of the groove 11 due to external forces during use, but also minimizes the restriction of the groove 11 on the elastic support frame 2, providing a sufficiently large degree of freedom for elastic deformation of the elastic support frame 2, especially the boss 21.

[0069] As can be seen from the above, the sink and the receiving groove provide clearance for the vertical elastic deformation of the boss 21, which not only improves the convenience and reliability of installation, but also enhances the structural stability of the entire module.

[0070] Based on the above specific embodiments, the limiting piece 12 is located at the position of the limiting groove, and its inner side contacts the outer wall of the support foot 23. When the elastic support frame 2 is installed in place, the support foot 23 will open the limiting piece 12, so that it is in close contact with the inner wall of the metal flange housing 3, thereby achieving grounding and ensuring the stability of signal transmission.

[0071] The limiting piece 12 is a thin metal sheet that is designed to be opened by the support foot 23 during the installation of the elastic support frame 2. The limiting piece 12 has an intermittent design with slots at both ends that transversely cut it off, leaving both ends free and connected only to the metal sheet at the lower end. This design allows the support foot 23 to more easily drive the limiting piece 12 to elastically deform in a direction perpendicular to the plate surface. Only a small elastic force is required to open the limiting piece 12, ensuring a tight fit between the limiting piece 12 and the inner hole 32 of the metal flange housing 3.

[0072] The limiting piece 12 and the spacer groove can be rectangular or square in shape, and their specific dimensions depend on the length of the limiting groove and the support foot 23, ensuring that the length and width of the limiting piece 12 can contact the outer wall of the support foot 23. The width of the spacer groove is less than the length of the limiting piece 12 to ensure that the limiting piece 12 has a large contact area with the support foot 23 and the inner hole 32 of the metal flange housing 3.

[0073] Based on the above specific embodiments, the upper end of the limiting piece 12 is bent inward to form a locking piece, which presses against the surface of the elastic support frame 2.

[0074] In practical applications, the locking piece is located at the upper end of the limiting piece 12, bent inward to form a protruding sheet-like structure. Its shape is typically rectangular or a triangle tapering from the root to the end, making it simple and easy to manufacture. The locking piece is parallel to the bottom surface of the groove 11. After the elastic support frame 2 is installed in place, the locking piece presses tightly against the surface of the elastic support frame 2, restricting its position during installation and ensuring accurate embedding within the groove 11. Simultaneously, the locking piece prevents the elastic support frame 2 from loosening, shifting, or detaching from the groove 11 during use, further enhancing the fixing effect and improving the stability and reliability of the module.

[0075] Based on the above specific embodiments, the outer wall of the support foot 23 forms a gradually expanding arc surface from the root to the end, the limiting piece 12 contacts the arc surface of the support foot 23, and the limiting groove at the end of the support foot 23 provides clearance space for elastic deformation of the length of the support foot 23.

[0076] In practical applications, the outer wall of the support foot 23 gradually expands outward from its root to its end, forming an arc surface. This arc surface structure concentrates the contact point between the support foot 23 and the limiting plate 12 at the protruding position of the arc surface, forming point contact rather than surface contact. During installation, the arc surface allows the limiting plate 12 to better adapt to elastic deformation. The limiting plate 12 slides along the arc surface of the support foot 23, further optimizing the installation process, improving installation efficiency, and reducing installation time and cost. During the process of the support foot 23 opening the limiting plate 12, the smaller contact area reduces friction, making the support foot 23 open the limiting plate 12 more smoothly and reducing the possibility of jamming or damage during installation. Although the contact point is small, the arc surface design still ensures stable contact between the support foot 23 and the limiting plate 12, ensuring the realization of the grounding function and thus guaranteeing the stability of signal transmission.

[0077] The limiting groove provides clearance space on the outer side of the support leg 23, located at the outer end of the limiting groove, that is, at the outer end of the support leg 23 along the length of the limiting groove. This clearance space provides elastic deformation space in the length direction for the support leg 23 during installation. During installation, when the support leg 23 expands the limiting piece 12, the support leg 23 may undergo elastic deformation in the length direction. The existence of the clearance space ensures that this deformation can proceed smoothly, avoiding installation failure or component damage due to obstructed deformation.

[0078] The design of the clearance space not only improves the reliability of installation and ensures that the elastic support frame 2 can be installed smoothly, but also ensures that the support foot 23 is not restricted during deformation, thus maintaining stability during use and further improving the overall stability of the module.

[0079] Based on the above specific embodiments, the elastic support frame 2 can be made of nylon. Nylon is an engineering plastic with excellent comprehensive properties, possessing high mechanical strength and the ability to withstand certain pressure and deformation. It also has good elasticity, allowing it to undergo elastic deformation during installation and return to a stable state after installation, making it very suitable for use as the elastic support frame 2 in the network port module.

[0080] The bracket includes an outer frame and a cross joint connected to the outer frame, with a boss 21 located at the center of the cross joint. The shape and size of the outer frame are adapted to the receiving groove of the insulating block, allowing it to be tightly embedded within the groove. The cross joint is located inside the outer frame and connected to it. Its design not only increases the structural strength of the elastic support frame 2 but also maximizes the elastic deformation capacity of the elastic support frame 2, while providing a stable installation position for the boss 21. The boss 21, acting as a limiting part, is located at the center of the cross joint and is used to cooperate with the limiting hole 31 of the metal flange housing 3 to achieve the module's fixing and limiting functions.

[0081] The flexible support frame 2 can be manufactured using a one-piece molding process. Its support legs 23, outer frame, cross-shaped components, and bosses 21 are injection molded in one piece, eliminating the need for subsequent assembly. This one-piece molding process eliminates gaps between components, improves the structural strength of the flexible support frame 2, and reduces the risk of structural failure due to loose connections. Simultaneously, it avoids errors that may occur during assembly, thereby enhancing product reliability and consistency. Furthermore, the one-piece molding process simplifies the production process, improves production efficiency, reduces production costs, and allows for precise control of the dimensional accuracy of each component, ensuring accurate fit between the flexible support frame 2 and components such as the insulating block and metal flange housing 3.

[0082] Based on the above specific embodiments, the metal sheet covers the bottom surface and two sides of the module body 1 to ensure that the module forms a good grounding connection with the metal flange housing 3 when it is installed, thereby realizing the grounding function of the network port module, reducing electromagnetic interference and improving the stability of signal transmission. The top surface of the module body 1 does not need to be covered with the metal sheet, thus reducing the overall size of the module.

[0083] In addition, the metal sheet also serves as electromagnetic shielding, preventing external electromagnetic interference from affecting the signal transmission inside the module, and also preventing signals inside the module from interfering with external devices. The metal sheet also provides additional mechanical protection for the module body 1, preventing physical damage to the module during installation and use.

[0084] Since the module body 1 is connected to a metal flange shell 3, the metal sheet wrapped around the insulating block does not need to be too thick. The thickness of the metal sheet can be arbitrarily selected between 0.2mm and 0.4mm, including endpoint values, such as 0.3mm. This thickness design ensures that the metal sheet has good conductivity and grounding performance while also providing a certain degree of flexibility. This allows the metal sheet to adapt to the shape of the module body 1 during installation and to undergo elastic deformation when the support foot 23 expands the limiting piece 12. Compared with the thicker metal layers in the prior art, the thinner metal sheet thickness in this application can significantly reduce material costs and the overall weight of the module.
