Therefore, Ethernet technology has become the most important local area network networking technology today, and network switches have become the most popular switches;

[0003] Currently, each module of the existing switch is plugged into the backplane of the switch. When the existing switch is in use, the network cable connectors at the data ports are manually plugged and unplugged. During the process of manually inserting the connectors, in order to ensure stable insertion between the connectors and the ports, a relatively large force is used for insertion, which easily leads to excessive contact force between the connectors and the inside of the ports, damaging the ports. At the same time, the existing switch has multiple interfaces for connecting multiple network cables. When there are many network cables, the heat dissipation performance of the switch and its ports is poor, resulting in an increase in the internal temperature of the machine, causing components to burn out.

As shown in the figure, the data ports 11 are located at the longitudinal front end of the switch body 1, and a plurality of protective shells 2 are installed on the outer side of the data ports 11 and located on the switch body 1. The number of the protective shells 2 and the number of the data ports 11 are in a one-to-one correspondence. The protective shells 2 are fastened to the outer side of the data port 11 by a sealant, and the outer side is the longitudinal front end of the data port 11;

[0035] The protective shell 2 is provided with an opening 23 connected to the data port 11, the opening 23 is located at the longitudinal front end of the data port 11, and the size of the opening 23 is not less than the size of the data port 11. A protective member 3 is provided inside the protective shell 2, and the protective member 3 protects the data port 11 when the plug connector is not connected. The use of the protective member 3 can improve the protection effect of the data port, so that the data port can be protected when it is not in use, and reduce the damage to the data port 11 by debris.

[0036] A guide member 4 is provided at the protective shell 2, and the guide member 4 includes two threaded sleeves 41 arranged at the top of the protective shell 2, and an air inlet hole connected to the threaded sleeve 41 is provided on the protective shell 2, a protective cover 42 is provided on the outside of the threaded sleeve 41, and a plurality of filter holes are provided on the top of the protective cover 42 to connect it with the air inlet hole, and a waterproof breathable membrane is installed inside the protective cover 42 and at the bottom corresponding to the hole, so as to prevent moisture contained in the air from entering the inside of the receiving groove 22, and the guide member 4 is used to introduce external gas into the protective shell, and the gas flows out through the outflow pipe 21 provided at the bottom of the protective shell 2, each of the outflow pipes 21 corresponds to a protective shell 2, and an air inlet shell 5 is provided between the plurality of outflow pipes 21, and further, the head ends of the plurality of outflow pipes 21 are connected to the respective corresponding protective shells, and the ends of the plurality of outflow pipes 21 are connected to the air inlet shell 5;

[0037] The air inlet shell 5 is installed at the bottom of the switch body 1. Two supporting feet 51 are provided at the bottom of the switch body 1 and located on the lateral outside of the air inlet shell 5. The two supporting feet 51 are both L-shaped. At the same time, anti-slip grooves are provided on the bottom of the supporting feet 51 to increase friction and improve the stability of the switch body 1. Fixing holes are provided on the supporting feet 51, which makes it convenient for the two supporting feet 51 of the switch body 1 to be fastened and connected with the corresponding equipment, thereby ensuring the stability of the switch body 1. The two supporting feet 51 are respectively provided with air guide holes 511 connected to the air inlet shell 5; a heat sink 6 is provided inside the air inlet shell 5, and the heat sink 6 includes a heat dissipation fan 61 installed inside the air inlet shell 5, and the heat dissipation fan 61 guides the airflow into the interior through multiple outflow pipes 21 and outputs it through the air guide holes 511.

[0038] An accommodation groove 22 is provided inside the protective housing 2, and the accommodation groove 22 communicates with the bottom of the rectangular opening 23;

[0039] The protective member 3 includes a protective plate 31 slidably connected to the accommodation groove 22. The running track of the protective plate 31 is to slide up and down in the accommodation groove so as to close or open the opening 23. Anti-slip patterns are provided on the lateral outer side of the protective plate 31, and a sealing gasket may also be provided on the outer side of the protective plate 31 to make the protective plate fit tightly with the opening 23, so as to facilitate the manual use of the finger to pull it down along the opening 23. The top of the protective plate 31 is located at the opening 23, and sealing members 32 are provided on both sides of the opening 23. When the protective plate 31 completely moves to the opening 23, the sealing members 32 seal the inside of the data port 11. The sealing members 32 include sealing strips 321 provided on both sides inside the opening 23, and the protective plate 31 is provided with a mating groove corresponding to the position of the sealing strip 321. When the top of the protective plate 31 moves to the top of the opening 23, the sealing strip 321 provided at the opening 23 is used to seal between the protective plate 31 and the port; further, the sealing strip 321 can also be arranged at the top of the opening 23, and a mating groove is also opened at the top of the corresponding protective plate 31 to further improve the sealing effect, which will not be elaborated here; this solution only shows one sealing method, that is, the sealing strips 321 are arranged on the lateral sides of the opening 23, and the protective plate 31 is provided with a mating groove corresponding to the position of the sealing strip 321, which will not be elaborated here;

[0040] A plurality of support members 33 for supporting the protective plate 31 are provided inside the accommodation groove 22. The support members 33 include a lifting block 331 fixedly installed at the bottom of the protective plate 31, and a support rod 332 slidably penetrates through the lifting block 331. Both the top and the bottom of the support rod 332 are fixedly connected to the inside of the accommodation groove 22. A buffer spring 333 is sleeved on the outer side of the support rod 332, and both ends of the buffer spring 333 are fixedly connected to the lifting block 331 and the accommodation groove 22 respectively; when the protective plate 31 is pulled down to expose the opening 23, the buffer spring 333 is stretched. At this time, the buffer spring 333 has a restoring force to reset the protective plate 31. However, in this state, the opening is blocked by the connector, and the restoring force of the buffer spring 333 acts on the connector to further fix the connector, ensuring stable insertion between the connector and the port;

[0041] The protective plate 31 is provided with an L-shaped connection hole 311. The bottom of the connection hole 311 is located on the side of the protective plate 31 close to the data port 11, and a negative pressure clamping member 7 is provided at the top of the connection hole 311. The negative pressure clamping member 7 includes a telescopic tube 71 with the bottom communicating with the connection hole 311. Further, the telescopic tube 71 can adjust its telescopic length to communicate the top of the connection hole 311 with the outlet hole 721. The top of the telescopic tube 71 is fixedly connected with a clamping block 72. The clamping block has an outlet hole 721 in a "T" shape, and a clamping hole is provided at the position corresponding to the clamping block 72 at the bottom of the network cable connector. Thus, during the process of pushing the connector into the data port 11, after the clamping block 72 is pressed, it relatively moves into the connection hole 311 until the clamping hole moves to the position of the clamping block 72. Then, under the reverse elastic force of the limiting spring 75, it is further clamped at the clamping hole of the network cable connector, realizing the positioning and clamping function of the network cable connector. At this time, it can not only ensure the secondary fixation of the network cable connector and the data port 11, prevent the network cable connector from detaching from the data port 11, but also play a role in prompting the operator, enabling the staff not to need to forcefully insert the network cable connector;

[0042] The clamping block 72 is provided with an outlet hole 721 communicating with the telescopic tube 71, and the outlet hole 721 is in a T shape (the cross-section in the height direction);

[0043] The top of the connection hole 311 is in a T shape (the cross-section in the height direction), so as to be able to accommodate the two limiting plates 73. Two limiting plates 73 are fixedly connected to the top of the clamping block 72. A limiting rod 74 slidably penetrates through the two limiting plates 73. The limiting rod 74 is fixedly connected with the connection hole 311. A limiting spring 75 is sleeved outside the limiting rod 74, and the two ends of the limiting spring 75 are respectively fixedly connected with the limiting plate 73 and the connection hole 311; when the clamping block 72 is pressed down, the limiting spring has an elastic force to reset it. When the clamping block 72 exactly coincides with the clamping hole of the network cable connector, the installation of the network cable connector on the switch is completed;

[0044] At the top of the opening 23, there is a moving hole for moving the top of the negative pressure clamping member 7. The purpose of this moving hole is to accommodate the clamping member 1 and adjust the connection between the connection hole 311 and the receiving groove 22. And at the top of the moving hole, there is a transfer member 34. The transfer member 34 adjusts the connection between the connection hole 311 and the receiving groove 22 through the negative pressure clamping member 7;

[0045] The transfer part 34 includes a limit cylinder 341 installed outside the moving hole. Two branch pipes 342 communicate with the bottom of the limit cylinder 341. A closing part 8 is arranged inside the limit cylinder 341. When the clamping block 72 is not connected to the limit cylinder 341, the closing part 8 keeps one end of the two branch pipes 342 closed with the inside of the limit cylinder 341. The closing part 8 includes a rubber plug 81 slidably connected inside the limit cylinder 341. The top of the rubber plug 81 is fixedly connected with a compression spring 82, and the compression spring 82 is installed at the top end inside the limit cylinder 341;

[0046] One end of each of the two branch pipes 342 away from each other is frustum-shaped. An adjusting part 9 is arranged at one end of the branch pipe 342. The adjusting part 9 includes an adjusting rod 91 slidably penetrating through the frustum-shaped end of the branch pipe 342. One end of the adjusting rod 91 located inside the branch pipe 342 is fixedly connected with a closing plug 92, and the closing plug 92 is frustum-shaped;

[0047] One end of the adjusting rod 91 away from the closing plug 92 is fixedly connected with a pushing plate 93. A guiding rod 94 slidably penetrates through the pushing plate 93. Both ends of the guiding rod 94 are fixedly connected with the inner wall of the accommodating groove 22 through guiding blocks 95 provided;

[0048] A tension spring 96 is sleeved outside the guiding rod 94. Both ends of the tension spring 96 are fixedly connected with the guiding block 95 and the pushing plate 93 respectively.

[0049] Specific implementation process: When connecting the network cable connector to the data port 11, manually push the protection plate 31 downward along the data port 11 by hand, and at the same time insert the network cable connector into the inside of the data port 11 along the opening 23 with the other hand. During the insertion process, on the one hand, the bottom of the protection plate 31 correspondingly moves to the bottom end inside the accommodating groove 22, and on the other hand, when the clamping hole at the bottom of the network cable plug moves to the clamping block 72, the clamping block 72 is pushed by the limit spring 75, and the top is clamped into the clamping hole to realize the function of limiting the network cable plug;

[0050] At this time, under the action of the compression spring 82, the rubber plug 81 moves to the two branch pipes 342. Then, through the limit cylinder 341, the opening 23 and the accommodating groove 22 are separated from each other. At this time, the heat dissipation fan 61 operates, and dry gas is introduced into the air inlet housing 5 through the filter holes, the accommodating groove 22 and the multiple outflow pipes 21. At the same time of introduction, the relatively low-temperature air flow flows through the accommodating groove 22, and further, the network cable connector and the data port 11 are cooled by the protection housing 2. At the same time, under the action of the heat dissipation fan 61, the switch body 1 is further cooled, and the relatively hot air flow is discharged through the air guiding holes 511.

[0051] When the network cable connector is not connected to the data port 11, the protection plate 31 is further moved upward along the opening 23 under the reverse elastic force of the plurality of buffer springs 333 at the support rod 332. When the protection plate 31 moves to the top of the opening 23, the clamping block 72 moves upward along the moving hole. While the clamping block 72 moves upward, it pushes the rubber plug 81 to move upward inside the limiting cylinder 341. Until the top of the clamping block 72 moves inside the limiting cylinder 341, at the same time, the lead-out hole 721 at the clamping block 72 communicates with the two branch pipes 342. At this time, the extrusion force of the compression spring 82 at the rubber plug 81 is the same as the supporting force of the limiting spring 75 at the clamping block 72, thereby ensuring that the clamping block 72 is stable inside the limiting cylinder 341;

[0052] At this time, the two branch pipes 342 are communicated with the connection hole 311 through the lead-out hole 721 and the telescopic spring. At the same time, the protection plate 31 separates the outside of the opening 23 from the data port 11. Then, when the cooling fan 61 sucks the outside air under negative pressure, the branch pipes 342 extract the gas between the protection plate 31 and the data port 11 through the connection hole 311. Until the negative pressure between the protection plate 31 and the data port 11 reaches a certain value, at this time, the closing plug 92 moves along the frustum end of the branch pipe 342 and closes one end of the branch pipe 342, further ensuring the negative pressure sealing inside the data port 11, and at the same time preventing the metal connectors at the data port 11 from being oxidized due to too much oxygen inside the data port 11.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
