[0035] The following detailed description and drawings of the embodiments of the present application are used to illustrate the principles of the present application, but cannot be used to limit the scope of the present application, that is, the present application is not limited to the described embodiments.

[0036] In the description of the present application, it should be noted that, unless otherwise specified, the terms "first" and "second" etc. are used for descriptive purposes only and shall not be understood as indicating or implying relative importance; "plurality" means two or more; the terms "inside", "outside", "top", "bottom" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore shall not be understood as limiting the present application.

[0037] See also Figure 1 and Figure 2 The embodiment of the present application provides a switch dustproof device, which includes a first wire shielding cover 1. In actual application, the first wire shielding cover 1 is connected to one end of the switch 4 to cover the interface of the network cable 5 and the optical fiber line 6. A first opening 11 is provided at one end of the first wire shielding cover 1, and a second opening 12 is provided at the other end of the first wire shielding cover 1. Specifically, the first opening 11 is provided toward the end surface of the switch 4 where the interface of the network cable 5 and the optical fiber line 6 is provided. A filling piece 13 is provided at the second opening 12. The size of the filling piece 13 is larger than the size of the second opening 12, so that the filling piece 13 and the second opening 12 are interference-fitted, thereby preventing dust from entering the first wire shielding cover 1 through the gap between the filling piece 13 and the second opening 12.

[0038] See also Figure 1 In the coordinate direction, x represents the thickness direction of the filler 13, y represents the width direction of the filler 13, and z represents the length direction of the filler 13. In a specific implementation, the filler 13 has a first surface and a second surface opposite to each other along its thickness direction, and has a third surface along its width direction, such as Figure 3As shown, the filling piece 13 is provided with a mounting hole 131, a first through groove 132 and a second through groove 133, wherein the mounting hole 131 extends from the first surface to the inside of the filling piece 13 along the thickness direction of the filling piece 13. The first through groove 132 extends from the first surface to the second surface along the thickness direction of the filling piece 13, and the first through groove 132 extends from the third surface along the width direction of the filling piece 13 to communicate with the mounting hole 131. The second through groove 133 corresponds to the mounting hole 131 in the thickness direction of the filling piece 13, and the second through groove 133 extends from the second surface along the thickness direction of the filling piece 13 to communicate with the mounting hole 131, and the second through groove 133 is communicated with the first through groove 132. Exemplarily, the filling piece 13 can be made of silicone material, which has good deformation and weather resistance, and the filling piece 13 is suitable for long-term use as an external part of the product. The thickness of the filling piece 13 can be 1 to 10 mm. For example, if the thickness of the filling piece 13 is 5 mm, the thickness at the corresponding mounting hole 131 can be 1 mm (i.e., the hole depth of the mounting hole 131 is 4 mm), and the dimensions of the first through groove 132 and the second through groove 133 along the length direction of the filling piece 13 can be 0.1 mm (i.e., the groove width is 0.1 mm, and the first through groove 132 and the second through groove 133 are a narrow gap).

[0039] In practical applications, when installing the network cable 5, the network cable 5 (with a crystal plug) and the filler 13 can be installed together first. Specifically, Figure 4 , Figure 5 and Figure 6 As shown, the filler 13 is opened along the first through slot 132, so that the network cable 5 passes through the first through slot 132 and the second through slot 133 and falls into the mounting hole 131, thereby putting the filler 13 on the network cable 5. Then, the filler 13 and the first wire shielding cover 1 are installed together. Specifically, the filler 13 is embedded in the second opening 12, and the second opening 12 squeezes the filler 13, the filler 13 is deformed, and the first through slot 132 and the second through slot 133 are closed, thereby playing a dustproof role and preventing dust from entering the first wire shielding cover 1. Then, the network cable 5 is plugged into the network cable interface of the switch 4, and the first wire shielding cover 1 is installed on the switch 4. When the number of network cables 5 is large, the number of second openings 12 can be multiple, and the number of fillers 13 is the same as the number of second openings 12. By using multiple fillers 13 to be respectively put on the network cables 5, the dustproof effect can be improved. Figure 1 The example shows a case where there are four second openings 12 and four filling members 13 .

[0040] By adopting the switch dustproof device of this embodiment, the network cable 5 does not need to be crimped with a crystal head on site, and the crystal head does not need to be reconnected during the operation and maintenance process. The installation and operation and maintenance of the network cable 5 are relatively convenient and efficient. The network port and wire connector of the switch 4 can be kept hidden, and the dustproof requirements of the network port of the switch 4 can be met, the dustproof level of the switch 4 can be improved, and the switch 4 can be compatible with multiple working conditions for installation, thereby increasing the value of the product.

[0041] As a possible implementation, Figure 3 As shown, the second through slot 133 may include a plurality of through slot structures 1331, each of which extends from the second surface along the thickness direction of the filler 13 to communicate with the mounting hole 131. Among the plurality of through slot structures 1331, one through slot structure 1331 is communicated with the first through slot 132, and the other through slot structures 1331 are arranged crosswise with the one through slot structure 1331. The arrangement of the plurality of through slot structures 1331 allows the network cable 5 to be more fully wrapped, and a gap is less likely to appear between the network cable 5 and the filler 13, and the dustproof effect is better. Figure 3 An example is given of a case where the second through slot 133 includes two through slot structures 1331, in which one through slot structure 1331 is connected to the first through slot 132, and the other through slot structure 1331 can cross and be vertically arranged with the one through slot structure 1331, that is, the second through slot 133 is embodied as a "cross" shaped structure.

[0042] In a possible embodiment, Figure 3 As shown, the filling piece 13 has a side surface connecting the first surface and the second surface, and the side surface is provided with a first positioning portion 134. The side wall of the second opening 12 is provided with a second positioning portion. One of the first positioning portion 134 and the second positioning portion is a protruding structure, and the other is a groove structure. The first positioning portion 134 and the second positioning portion are clamped to achieve the filling piece 13 being installed in the second opening 12.

[0043] In a specific implementation, the filling piece 13 has a side surface connecting the first surface and the second surface, and a third positioning portion 135 is provided on the side surface, and the third positioning portion 135 extends from the side surface to a direction away from the side surface. The size of the third positioning portion 135 is larger than the size of the second opening 12, which can limit the movement of the filling piece 13 relative to the second opening 12, and can improve the installation stability of the filling piece 13. The third positioning portion 135 is provided close to the second surface in the thickness direction of the filling piece 13, which can limit the filling piece 13 from sliding into the first wire shielding cover 1. Specifically, the third positioning portion 135 can be flush with the second surface.

[0044] In actual setting, there can be multiple mounting holes 131, and multiple mounting holes 131 are arranged in an array. The number of first through slots 132 and second through slots 133 is the same as the number of mounting holes 131, one first through slot 132 is connected to one mounting hole 131, one second through slot 133 corresponds to one mounting hole 131, and one second through slot 133 is connected to one first through slot 132. The filler 13 can fill the gap between the network cable 5 and the wires, and the number of network cables 5 can be flexibly adjusted, which can realize flexible application of multiple network ports and meet the dustproof requirements of multiple network ports of the switch 4.

[0045] As a possible implementation, Figure 2 As shown, one end of the first wire shielding cover 1 provided with the first opening 11 has a first connection end face, the first connection end face is used to connect with the end face of the switch 4, and the first connection end face is provided with a gasket 14, and the gasket 14 surrounds the first opening 11. When the first wire shielding cover 1 is connected to the switch 4, the gasket 14 is located between the first connection end face and the end face of the switch 4. The gasket 14 can prevent dust from entering the gap between the first wire shielding cover 1 and the end face of the switch 4. Specifically, the gasket 14 can be made of foam.

[0046] In actual application, the optical fiber line 6 is led out from the cable management frame 3 on the bottom (back) of the switch 4 and inserted into the same port side of the switch 4 as the network cable 5. The gasket 14 can cover the optical fiber line 6. Since the diameter of the optical fiber line 6 is small, the gasket 14 can wrap the optical fiber line 6 and fill the gaps between the optical fiber lines 6 and the gaps between the optical fiber lines 6 and the structural parts. In addition, the first cable cover 1 can cover the optical fiber line 6 inside to hide the optical fiber line 6, achieve the effect of cable protection, and prevent the optical fiber line 6 from being exposed and damaged, worn, etc.

[0047] In a specific implementation, a partition 15 is provided inside the first wire shielding cover 1. The partition 15 extends from one end of the first wire shielding cover 1 to the other end. The internal space of the first wire shielding cover 1 is divided into a first space and a second space by the partition 15. The first space is used to accommodate the network cable 5, and the second space is used to accommodate the optical fiber 6. Thus, the second space can be used as an independent wiring space for the optical fiber 6 in the first wire shielding cover 1. The partition 15 has a second connection end face at one end corresponding to the first opening 11. The second connection end face is used to connect with the end face of the switch 4. The second connection end face is provided with a first gasket 16. The two ends of the first gasket 16 are respectively connected to the gasket 14. Specifically, the first gasket 16 can be made of foam. The first gasket 16 cooperates with the gasket 14 to form a circle of independent dustproof for the routing of the optical fiber 6 in the second space. Of course, it also forms a circle of independent dustproof for the routing of the network cable 5 in the first space, thereby improving the dustproof effect.

[0048] As a possible implementation, Figure 7 and Figure 8 As shown, the switch dustproof device also includes a wire management rack 3, which is used to be arranged on the bottom surface of the switch 4 to manage the optical-electrical hybrid cable, the electric wire, the optical fiber cable 6, etc. One end of the wire management rack 3 is connected to the first wire shielding cover 1, and the other end of the wire management rack 3 is connected to the second wire shielding cover 2. The second wire shielding cover 2 has a third connection end surface, and the third connection end surface is used to connect with the other end surface of the switch 4. The third connection end surface is provided with a second gasket 21. Specifically, the second gasket 21 can be made of foam.

[0049] In actual application, the wires are led out from the wire management rack 3 on the bottom of the switch 4, plugged into the other port side of the switch 4 (non-network port side), and plugged into the wire port. After the wires are connected, the second wire shielding cover 2 is connected to the switch 4, and the second gasket 21 can wrap the wires to prevent dust from entering the switch 4 from the wire port. In addition, a sealing sheet 41 can be provided at the corresponding wire port of the switch 4. The sealing sheet 41 can cover the gap between the wire terminal and the structural opening to prevent dust, and can cooperate with the second gasket 21 to fill the gaps between the wires and the wires to enhance the dustproof effect. Specifically, the sealing sheet 41 can be made of silicone.

[0050] In a specific implementation, one end of the second wire shielding cover 2 is connected to the wire management frame 3, and the other end of the second wire shielding cover 2 is provided with a buckle structure 22, which is used to be connected to the other end face of the switch 4, and the buckle structure 22 is sleeved with a sealing ring 23. The other end face of the switch 4 is provided with a mounting groove, and the mounting groove is used for the buckle structure 22 to be inserted, so that the second wire shielding cover 2 is buckled on the switch 4. After the second wire shielding cover 2 is buckled with the switch 4, the sealing ring 23 can block the gap between the buckle structure 22 and the mounting groove to prevent dust from entering the switch 4.

[0051] like Fig. 9 As shown, an embodiment of the present application also provides a switch, including a switch dustproof device as in the above embodiment, wherein a first wire shielding cover 1 is connected to an end face of the switch 4, a second wire shielding cover 2 is connected to the other end face of the switch 4, and a wire management rack 3 is arranged on the bottom face of the switch 4, which can improve the dustproof level of the switch 4, so that the switch 4 can be compatible with multiple working conditions installation.

[0052] Those skilled in the art should understand that the above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
