The connection component 2 is fixedly connected to one side of the switch component 1, and the expansion component 3 is plugged into one side of the connection component 2. The connection component 2 includes a connection sleeve mechanism 201 and an anti-disconnection mechanism 202. The connection sleeve mechanism 201 includes a connection sleeve body 2011 and a slot 2012 formed inside the connection sleeve body 2011. The connection sleeve body 2011 serves as the basic frame of the connection component 2, integrating the slot 2012 and the anti-disconnection mechanism 202. It is a physical bridge connecting the switch body 101 and the expansion component. The slot 2012 is used to accommodate the connection part 302 of the expansion component, providing insertion space and initial positioning for the expansion module. The anti-disconnection mechanism 202 includes a positioning frame 2021 fixedly connected to the top of the inner cavity of the connection sleeve body 2011 and a guide sleeve 2023 fixedly connected to one side of the positioning frame 2021. The expansion assembly includes a fitting groove 2024 on the inner wall of the guide sleeve 2023, a limiting groove 2022 at the bottom of the positioning frame 2021, and a splitter plate 2025 fixedly connected to one side of the positioning frame 2021 and extending into the interior of the switch assembly 1, with the top of the splitter plate 2025 extending to the outside of the switch assembly 1. The positioning frame 2021 is used to form a positioning after inserting into the positioning groove 305 of the expansion assembly, and also serves as a fixing carrier for the splitter plate 2025. The guide sleeve 2023 is used to guide the insertion direction of the expansion assembly, further improving the insertion and removal accuracy. The fitting groove 2024 is tightly fitted with the fitting protrusion 3011 of the expansion assembly to form a seal, preventing moisture and dust from entering from the connection. The limiting groove 2022 is used to engage with the limiting block 309 of the expansion assembly to form a locking structure, preventing the expansion module from accidentally falling off during vibration or accidental contact. The splitter plate 2025 is used to guide the airflow path and work with the cooling fan 104 to accelerate heat dissipation.The expansion component 3 includes a plug 301, a mating protrusion 3011 fixedly connected to one side of the plug 301, a connecting portion 302 fixedly connected to one side of the mating protrusion 3011, a positioning groove 305 formed on the top of the connecting portion 302, a metal spring 306 fixedly connected inside the plug 301, a pressing plate 307 fixedly connected to one end of the metal spring 306, a spring 308 fixedly connected to the top of the metal spring 306 and extending into the positioning groove 305, a limiting block 309 fixedly connected to the top of the spring 308, and an expansion groove 3010 connected to the other end of the plug 301 via a cable strip. The plug 301 serves as an expansion... The basic frame of the expansion component includes a fitting protrusion 3011 for tight contact with the fitting groove 2024 of the connecting component 2, providing a mechanical seal. The connecting part 302 is inserted into the slot 2012 of the connecting sleeve body 2011 and is the core part for the physical connection between the expansion component and the connecting component 2. It integrates electrical contacts that correspond to the pins in the slot 2012 to achieve data and power transmission. The positioning groove 305 accommodates the positioning frame 2021 of the connecting component 2, forming a longitudinal positioning. It works with the positioning frame 2021 to limit the vertical displacement of the module and improve the overall connection accuracy. The metal spring 306 is used when the press plate 307 is pressed. The spring 308 and the limiting block 309 move downwards, causing the limiting block 309 to disengage from the limiting groove 2022, thus unlocking the module and facilitating disassembly. The pressing plate 307 is used to easily press the metal spring 306, and the spring 308 provides continuous elastic force to the limiting block 309, ensuring its stable engagement in the limiting groove 2022; at the same time, it buffers the impact force during insertion and removal, protecting the structure. The limiting block 309, under the elastic force of the spring 308, engages with the limiting groove 2022 of the connecting component 2, forming a lock to prevent the module from falling off. The expansion slot 3010, located at the other end of the plug 301, is the functional interface for expanding the module, used to connect external devices or... The lower-level network expands the number and type of switch ports. This invention designs a connecting component 2 and an expansion component 3. When the connecting component 2 and the expansion component 3 are connected, the connecting part 302 is inserted into the slot 2012. At this time, the positioning bracket 2021 is located inside the positioning groove 305, and the limiting block 309 is engaged inside the limiting groove 2022, forming a stable limiting structure that effectively prevents the expansion module from loosening or falling off. Simultaneously, the fitting protrusion 3011 and the fitting groove 2024 are in a fitted state, preventing moisture and dust from entering and corroding the internal pins, thus improving the sealing at the connection between the connecting component 2 and the expansion component 3.

[0014] Specifically, the switch component 1 includes a switch body 101, a connection port 103 fixedly connected to the front surface of the switch body 101, a mounting bracket 102 fixedly connected to the rear surface of the switch body 101, a cooling fan 104 screwed to one side of the switch body 101, and a through hole 105 opened on the top of the switch body 101 and cooperating with the splitter board 2025. The switch body 101 serves as the basic framework of the entire device, integrating key components such as the core switching engine, power module, and control system bus. It is the central hub for data forwarding, device control, and the collaborative work of various components. The connection port 103 is used to directly connect to external network devices and is the interface for the switch to establish an initial connection with the external network. The mounting bracket 102 is used to fix the switch body 101 in the installation position such as a cabinet or rack to prevent the device from shaking or tipping over and to ensure long-term stable operation. The cooling fan 104 is used to accelerate the dissipation of heat inside the device by forced airflow to avoid performance degradation or failure due to overheating. The through hole 105 is used to provide an outlet for the splitter board 2025 and also serves as part of the heat dissipation channel to help exhaust heat from inside the device.

[0015] More specifically, the inner cavity of the connecting sleeve body 2011 has a slot 2012 and guide grooves 2013 are provided on both sides. An arc-shaped spring piece 2014 is installed inside the guide groove 2013. Guide blocks 303 that cooperate with the guide groove 2013 are fixedly connected to both sides of the connecting part 302. An arc-shaped groove 304 that cooperates with the arc-shaped spring piece 2014 is provided on the surface of the guide block 303. The guide groove 2013 is used to ensure that the expansion module is pushed along a precise path when inserted to avoid misalignment. The arc-shaped spring piece 2014 is used to fit with the arc-shaped groove 304 of the guide block 303 and generate elastic deformation when inserted, which not only enhances the tightness of the connection, but also provides moderate damping and facilitates control of the insertion and removal force. The guide block 303 is used to cooperate with the guide groove 2013 of the connecting component 2 to ensure that the expansion module is accurately inserted along the preset path. The arc-shaped groove 304 is used to fit with the arc-shaped spring piece 2014 in the guide groove 2013, which enhances the tightness of the connection through elastic force, while buffering the impact during insertion and removal.

[0016] It is worth mentioning that the bottom of the inner cavity of the positioning groove 305 is provided with a movable groove that cooperates with the spring 308. The movable groove is used to provide extension and retraction space for the spring 308 and the limiting block 309, ensuring that the limiting block 309 can flexibly engage / disengage from the limiting groove 2022. The top surface of the plug 301 is provided with a clearance groove that cooperates with the metal spring 306. The clearance groove provides space for the deformation of the metal spring 306, avoiding interference between it and the outer shell of the plug 301, and ensuring the normal operation of the pressing plate 307.

[0017] It is worth noting that the splitter plate 2025 is designed in a wave shape, and the ripples of the splitter plate 2025 gradually increase in size from the inside to the outside. This design allows the air generated by the cooling fan to be distributed more evenly inside the switch body 101. The splitter plate 2025 is made of graphene material, which has excellent thermal conductivity. The part of the splitter plate 2025 that extends outside the switch body 101 is provided with heat dissipation holes 2026, which can directly exhaust heat from the device and enhance the heat dissipation effect.

[0018] Working principle: This embodiment provides an Ethernet switch with a modular expansion slot. When it is needed to connect the expansion component 3 to the connection component 2, the connection part 302 is aligned with the slot 2012, and the guide block 303 is aligned with the guide groove 2013 and inserted. During the insertion process, the arc-shaped spring piece 2014 contacts the arc-shaped groove 304 and generates elastic deformation, providing moderate damping. As the insertion depth increases, the positioning bracket 2021 gradually enters the positioning groove 305. After full insertion, the fitting protrusion 3011 fits tightly with the fitting groove 2024. At this time, the spring 308 pushes the limiting block 309 into the limiting groove 2022 to complete the locking. During the disassembly process, the pressing plate 307 is pressed down, and the metal spring piece 306 deforms, causing the spring 308 and the limiting block 309 to move down, so that the limiting block 309 disengages from the limiting groove 2022. At this time, the expansion component 3 can be pulled out from the connection component 2.
