Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0055] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0056] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0057] The terms “first,” “second,” and “third” (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0058] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0059] An optical module cage is a metal frame or housing designed for mounting and securing optical modules. The cage has an interface that connects the inside and outside of the housing. The optical module is inserted into the interface and connects to devices inside the housing.

[0060] The related technology discloses an installation architecture and communication equipment for a communication module. The various boards forming the interface in this architecture do not have heat dissipation structures such as heat dissipation vents. After the optical module is plugged into the interface, the heat generated by the optical module cannot be quickly conducted to the air. Therefore, the heat dissipation performance of the optical module cage in the related technology is poor, which affects the signal transmission efficiency.

[0061] This application provides an optical module cage 100, a switch housing 1000, and a switch. The optical module cage 100 has an interface 100b and a heat dissipation channel 100a. The interface 100b is used to plug in an optical module. The heat dissipation channel 100a connects the interface 100b and the outside of the optical module cage 100. Under the action of the heat dissipation channel 100a, the heat generated by the operation of the optical module can be quickly flowed to the outside of the optical module cage 100 through the heat dissipation channel 100a, or the cold air outside the optical module cage 100 can enter the interface 100b through the heat dissipation channel 100a to absorb the heat generated by the optical module, so that the optical module can dissipate heat quickly. The optical module cage 100 of this application has good heat dissipation performance, which ensures the efficiency of signal transmission in the optical module.

[0062] In the attached diagram, X represents the first direction, Y represents the third direction, and Z represents the second direction. The first, second, and third directions are perpendicular to each other.

[0063] The following describes in detail, with reference to the accompanying drawings, an optical module cage 100, a switch housing 1000, and a switch provided in the embodiments of this application.

[0064] like Figure 1 As shown, the optical module cage 100 has a heat dissipation channel 100a and a plurality of interfaces 100b for inserting optical modules. The plurality of interfaces 100b are arranged in an array along a first direction and a second direction, the first direction and the second direction being perpendicular. Along the first direction, a heat dissipation channel 100a is provided between two adjacent interfaces 100b, and / or, along the second direction, a heat dissipation channel 100a is provided between two adjacent interfaces 100b. The heat dissipation channel 100a connects the interfaces 100b and the outside of the optical module cage 100.

[0065] The optical module cage 100 can be made of various materials, including metals and non-metals. Metals include iron and copper, while non-metals include plastics and ceramics. This application does not impose any limitations on the materials used. Multiple interfaces 100b are provided, allowing multiple optical modules to be simultaneously connected to the optical module cage 100. One or more optical modules can be connected to a single interface 100b; this application does not impose any limitations on the materials used.

[0066] The array distribution of multiple interfaces 100b along the first and second directions means that the multiple interfaces 100b are spaced apart along both the first and second directions, resulting in a multi-row, multi-column array distribution. This array distribution of multiple interfaces 100b makes the interfaces more compact, helping to improve the space utilization of the optical module cage 100 and allowing the optical module cage 100 to accommodate more interfaces 100b.

[0067] Along the first direction, a heat dissipation channel 100a is provided between two adjacent interfaces 100b, and / or, along the second direction, a heat dissipation channel 100a is provided between two adjacent interfaces 100b. That is, along the first direction, a heat dissipation channel 100a is provided between two adjacent interfaces 100b; or, along the second direction, a heat dissipation channel 100a is provided between two adjacent interfaces 100b; or, along the first direction, a heat dissipation channel 100a is provided between two adjacent interfaces 100b, and along the second direction, a heat dissipation channel 100a is also provided between two adjacent interfaces 100b.

[0068] The heat dissipation channel 100a is set between two adjacent interfaces 100b, making use of the area between the two adjacent interfaces 100b. This makes the arrangement of the interfaces 100b and the heat dissipation channel 100a more compact, which helps to improve the space utilization of the optical module cage 100. This allows the optical module cage 100 to set more interfaces 100b and accommodate more optical modules.

[0069] One side of the heat dissipation channel 100a connects to the interface 100b, and the other side connects to the outside of the optical module cage 100. This design allows the interface 100b to communicate with the outside air, enabling airflow between the interface 100b and the outside of the optical module cage 100. Specifically, air inside the interface 100b can flow through the heat dissipation channel 100a to the outside of the optical module cage 100, and air outside the optical module cage 100 can flow through the heat dissipation channel 100a back into the interface 100b. In this way, when the optical module is plugged into the interface 100b, the heat generated by the optical module can be quickly dissipated through the heat dissipation channel 100a to the outside of the optical module cage 100, or cool air outside the optical module cage 100 can enter the interface 100b through the heat dissipation channel 100a to absorb the heat generated by the optical module, thus rapidly dissipating heat. The optical module cage 100 of this application has good heat dissipation performance, ensuring the efficiency of signal transmission within the optical module.

[0070] like Figure 15As shown, it should be noted that interface 100b extends through the optical module cage 100. When the optical module cage 100 is installed on the switch housing 200, interface 100b connects the inside and outside of the housing 200. The optical module is plugged into interface 100b and connected to the port of the corresponding component inside the housing 200, such as the switch SFP+ port.

[0071] The heat dissipation device, circuit board, management engine, system controller, switching module, and other components of the switch are installed inside the housing 200, which provides protection for the components installed therein. The shape and structure of the housing 200 are diverse and are not limited in this application. In some embodiments, such as... Figure 15 As shown, the housing 200 is rectangular and has six sides, and the optical module cage 100 is mounted on the front side of the housing 200.

[0072] Optical modules come in various types, and this application does not limit them. Optical modules can be divided into optical receiver modules, optical transmitter modules, optical transceiver modules, and optical repeater modules, etc. The main function of optical transceiver modules is to realize photoelectric / electro-optic conversion, including optical power control, modulation and transmission, signal detection, and limiting, amplification, decision, and regeneration functions. Common types include SFP, SFP+, XFP, SFP28, QSFP+, and QSFP28.

[0073] In some embodiments, interface 100b extends along a third direction.

[0074] like Figure 1 and Figure 5 As shown, in some embodiments, the optical module cage 100 includes an outer frame assembly 110 and a partition mechanism 120. The outer frame assembly 110 has a mounting cavity 110a; the partition mechanism 120 is disposed within the mounting cavity 110a and connected to the outer frame assembly 110; the partition mechanism 120 has an interface 100b and a heat dissipation channel 100a, and the partition mechanism 120 and the outer frame assembly 110 also enclose the interface 100b.

[0075] The intermediate partition mechanism 120 is fixedly connected within the mounting cavity 110a of the outer frame assembly 110, and can be fixedly connected by bolts, adhesive, snap-fit, or other methods. The intermediate partition mechanism 120 itself has an interface 100b. After the intermediate partition mechanism 120 and the outer frame assembly 110 are fixedly connected, the intermediate partition mechanism 120 and the outer frame assembly 110 together form the interface 100b. When using the optical module cage 100, the outer frame assembly 110 can be connected to the switch housing 200 or other components, or the intermediate partition mechanism 120 can be connected to the switch housing 200 or other components; this application does not impose any limitations. Dividing the optical module cage 100 into two parts, the outer frame assembly 110 and the intermediate partition mechanism 120, allows the outer frame assembly 110 and the intermediate partition mechanism 120 to be manufactured separately, and then connected to form the optical module cage 100, thus facilitating the manufacturing of the optical module cage 100.

[0076] In some embodiments, the outer frame assembly 110 has a heat dissipation hole 110b, which is connected to the interface 100b and the outside of the optical module cage 100.

[0077] The heat dissipation hole 110b is a through hole that penetrates the outer frame assembly 110. The heat dissipation hole 110b connects the interface 100b and the outside of the optical module cage 100, allowing the heat generated by the optical module during operation to flow quickly to the outside of the optical module cage 100 through the heat dissipation hole 110b. Alternatively, cool outside air can enter the interface 100b through the heat dissipation hole 110b and absorb the heat from the optical module. With this design, the optical module cage 100 can dissipate heat not only through the heat dissipation channel 100a but also through the heat dissipation hole 110b, enabling rapid heat dissipation of the optical module and further improving the heat dissipation performance of the optical module cage 100 in this application, thus ensuring the efficiency of signal transmission within the optical module.

[0078] like Figure 1 and Figure 3 As shown, in some embodiments, the outer frame assembly 110 includes a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114. The first plate 111 and the second plate 112 are spaced apart along a second direction; the third plate 113 and the fourth plate 114 are spaced apart along a first direction and are both connected to the first plate 111 and the second plate 112; the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 enclose a mounting cavity 110a, and a partition mechanism 120 is connected to at least one of the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114.

[0079] The first plate 111 and the second plate 112 are arranged sequentially along a second direction, with a certain distance between them. The third plate 113 and the fourth plate 114 are arranged sequentially along a first direction, with a certain distance between them. The third plate 113 is fixedly connected to the first plate 111 and to the second plate 112; the fourth plate 114 is fixedly connected to the first plate 111 and to the second plate 112. The fixing method is varied, such as snap-fitting, bonding, welding, etc. After connection, the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 form a quadrilateral frame structure, which can be rectangular, square, trapezoidal, etc. The partition mechanism 120 can be connected to one of the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114, or it can be connected to multiple of them simultaneously. The outer frame assembly 110 includes a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114, which allows the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 to be processed individually and then connected to form the outer frame assembly 110, thus facilitating the manufacturing of the outer frame assembly 110.

[0080] In some embodiments, the third plate 113 is snapped into the first plate 111, the third plate 113 is snapped into the second plate 112, the fourth plate 114 is snapped into the first plate 111, and the fourth plate 114 is snapped into the second plate 112.

[0081] In some embodiments, the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 are all rectangular, and the first plate 111 and the second plate 112 have the same dimensions, as do the third plate 113 and the fourth plate 114. The first plate 111 and the second plate 112 are both perpendicular to the second direction, and the third plate 113 and the fourth plate 114 are both perpendicular to the first direction. The first plate 111, the second plate 112, the third plate 113, and the fourth plate 114 are connected end to end, so that the outer frame assembly 110 has a rectangular frame structure.

[0082] In some embodiments, both the third plate 113 and the fourth plate 114 are provided with a plurality of heat dissipation holes 110b.

[0083] In some embodiments, a plurality of heat dissipation holes 110b are provided on the first plate 111, the second plate 112, the third plate 113 and the fourth plate 114.

[0084] In some embodiments, the partition mechanism 120 is connected to the first plate 111, the second plate 112, the third plate 113 and the fourth plate 114 to ensure the connection strength between the partition mechanism 120 and the outer frame assembly 110.

[0085] like Figure 1, Figure 2 , Figure 9 and Figure 10 As shown, in some embodiments, the outer frame assembly 110 further includes a first clamping member 115, which is mounted on at least one of the first plate 111, the second plate 112, the third plate 113, and the fourth plate 114; the first clamping member 115 has a first elastic portion 1151 located within the interface 100b for abutting against the optical module.

[0086] The first clamping member 115 can be provided only on the first plate 111, the second plate 112, the third plate 113, or the fourth plate 114, or the first clamping member 115 can be provided on all of them simultaneously. The first elastic portion 1151 of the first clamping member 115 can undergo elastic deformation under external force, and after the external force is removed, the first elastic portion 1151 can return to its state before deformation. The first elastic portion 1151 is located inside the interface 100b. When the optical module is inserted into the interface 100b, the first elastic portion 1151 and the outer wall of the optical module press against each other to prevent the optical module from loosening.

[0087] In some implementations, the first plate 111, the second plate 112, the third plate 113 and the fourth plate 114 are all provided with a first clamping member 115.

[0088] In some embodiments, the first clamping member 115 further includes a first snap-fit ​​portion 1153 and a second elastic portion 1152. The first elastic portion 1151 and the second elastic portion 1152 are connected, and the first snap-fit ​​portion 1153 is connected to the first elastic portion 1151. The first elastic portion 1151 and the second elastic portion 1152 are disposed opposite to each other along a first direction. Under the action of an external force, the second elastic portion 1152 can undergo elastic deformation. After the external force is removed, the second elastic portion 1152 can return to its state before deformation. The first elastic portion 1151 is located inside the interface 100b and is used to abut against the optical module. The second connecting portion is located outside the interface 100b and is used to abut against the housing 200 of the switch. The first plate 111, the second plate 112, the third plate 113, or the fourth plate 114 are provided with first snap-fit ​​holes 110c at corresponding positions, and the first snap-fit ​​portion 1153 snaps into the first snap-fit ​​hole 110c.

[0089] In some embodiments, the first clamping member 115 is formed by bending a metal plate with a certain elasticity, the first elastic portion 1151 protrudes outward toward the side away from the second elastic portion 1152, and the second elastic portion 1152 protrudes outward toward the side away from the first elastic portion 1151.

[0096] like Figure 5 and Figure 7As shown, in some embodiments, the partition mechanism 120 includes a plurality of upright plate assemblies 121 and a plurality of horizontal plate assemblies 125. The plurality of upright plate assemblies 121 are spaced apart along a first direction and located within a mounting cavity 110a, and connected to the outer frame assembly 110. The plurality of horizontal plate assemblies 125 are all located within the mounting cavity 110a, and are respectively located between two adjacent upright plate assemblies 121 and between the outer frame assembly 110 and the upright plate assemblies 121. The horizontal plate assemblies 125 are connected to two adjacent upright plate assemblies 121, or connected to the upright plate assembly 121 and the outer frame assembly 110. The plurality of horizontal plate assemblies 125 between two adjacent upright plate assemblies 121 are spaced apart along a second direction, and the plurality of horizontal plate assemblies 125 between the outer frame assembly 110 and the upright plate assemblies 121 are also spaced apart along a second direction. The upright plate assemblies 121 and / or the horizontal plate assemblies 125 have heat dissipation channels 100a.

[0097] Some horizontal plate assemblies 125 are located between two adjacent vertical plate assemblies 121, and some horizontal plate assemblies 125 are located between the vertical plate assemblies 121 and the outer frame assembly 110. One side of the horizontal plate assembly 125 located between two adjacent vertical plate assemblies 121 is connected to one of the vertical plate assemblies 121, and the other side is connected to the other vertical plate assemblies 121. One side of the horizontal plate assembly 125 located between the vertical plate assemblies 121 and the outer frame assembly 110 is connected to the vertical plate assembly 121, and the other side is connected to the horizontal plate assembly 125. In these embodiments, some interfaces 100b are formed by the vertical plate assemblies 121 and horizontal plate assemblies 125, and some interfaces 100b are formed by the vertical plate assemblies 121, horizontal plate assemblies 125, and outer frame assembly 110. The vertical plate assemblies 121 and horizontal plate assemblies 125 space the various interfaces 100b apart. The upright plate assembly 121 has a heat dissipation channel 100a, or the horizontal plate assembly 125 has a heat dissipation channel 100a, or both the upright plate assembly 121 and the horizontal plate assembly 125 have heat dissipation channels 100a. The horizontal plate assembly 125 and the upright plate assembly 121 can be connected by snap-fit, bolt connection, or other means. Similarly, the outer frame assembly 110 and the upright plate assembly 121 can be connected by snap-fit, bolt connection, or other means. Likewise, the horizontal plate assembly 125 and the outer frame assembly 110 can also be connected by snap-fit, bolt connection, or other means. This application does not impose any limitations on these methods. In these embodiments, the partition mechanism 120 includes multiple upright plate assemblies 121 and multiple horizontal plate assemblies 125. Each upright plate assembly 121 and each horizontal plate assembly 125 can be manufactured separately and then assembled to form the partition mechanism 120, which facilitates the manufacturing of the partition mechanism 120.

[0098] Specifically, in embodiments where the outer frame assembly 110 includes a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114, a portion of the horizontal plate assembly 125 is located between the vertical plate assembly 121 and the third plate 113, and a portion of the horizontal plate assembly 125 is located between the vertical plate assembly 121 and the fourth plate 114. One side of the horizontal plate assembly 125 located between the vertical plate assembly 121 and the third plate 113 is connected to the vertical plate assembly 121, and the other side is connected to the third plate 113. Similarly, one side of the horizontal plate assembly 125 located between the vertical plate assembly 121 and the fourth plate 114 is connected to the vertical plate assembly 121, and the other side is connected to the fourth plate 114. Figure 1 and Figure 2 As shown, some interfaces 100b are formed by a first plate 111, a third plate 113, a horizontal plate assembly 125, and a vertical plate assembly 121; some interfaces 100b are formed by a first plate 111, a fourth plate 114, a horizontal plate assembly 125, and a vertical plate assembly 121; some interfaces 100b are formed by a second plate 112, a third plate 113, a horizontal plate assembly 125, and a vertical plate assembly 121; and some interfaces 100b are formed by a third plate 113, a fourth plate 114, a horizontal plate assembly 125, and a vertical plate assembly 121. The plate assembly 125 and the upright plate assembly 121 are enclosed together. Some interfaces are enclosed by the first plate 111, the horizontal plate assembly 125 and the upright plate assembly 121. Some interfaces 100b are enclosed by the second plate 112, the horizontal plate assembly 125 and the upright plate assembly 121. Some interfaces 100b are enclosed by the third plate 113, the horizontal plate assembly 125 and the upright plate assembly 121. Some interfaces 100b are enclosed by the fourth plate 114, the horizontal plate assembly 125 and the upright plate assembly 121.

[0099] In some embodiments, the optical module cage 100 is provided with three upright plate assemblies 121 and 28 horizontal plate assemblies 125. There are 7 horizontal plate assemblies 125 between two adjacent upright plate assemblies 121, 7 horizontal plate assemblies 125 between an upright plate assembly 121 and a third plate 113, and 7 horizontal plate assemblies 125 between an upright plate assembly 121 and a fourth plate 114, forming a total of 24 interfaces 100b.

[0100] like Figure 6 and Figure 8 As shown, in some embodiments, the upright plate assembly 121 includes a first upright plate 122 and a second upright plate 123. The first upright plate 122 is connected to the outer frame assembly 110 and has a first heat dissipation hole 122a. The second upright plate 123 is connected to the outer frame assembly 110 and has a second heat dissipation hole 123a. Along a first direction, a first gap 121a is formed between the second upright plate 123 and the first upright plate 122; the first heat dissipation hole 122a, the second heat dissipation hole 123a, and the first gap 121a form a heat dissipation channel 100a.

[0101] A first gap 121a exists between the second upright plate 123 and the first upright plate 122, meaning that the second upright plate 123 and the first upright plate 122 are spaced apart along a first direction, with a gap between them along the first direction. A first heat dissipation hole 122a connects the interface 100b and the first gap 121a, and a second heat dissipation hole 123a also connects the interface 100b and the first gap 121a. Heat generated by the optical module in the interface 100b flows through the first heat dissipation hole 122a or the second heat dissipation hole 123a into the first gap 121a, and then flows along the first gap 121a to the outside of the optical module cage 100. Outside cold air can enter the interface 100b through the first gap 121a, the first heat dissipation hole 122a, and the second heat dissipation hole 123a, absorbing the heat from the optical module and enabling rapid heat dissipation from the optical module.

[0102] like Figure 1 , Figure 2 , Figure 4 , Figure 13 and Figure 14 In some embodiments, the upright plate assembly 121 further includes a second clamping member 124, which is mounted on the first upright plate 122 and / or the second upright plate 123. The second clamping member 124 has a third elastic portion 1241 and a fourth elastic portion 1242, which are respectively located in two adjacent interfaces 100b along the first direction.

[0103] The second clamping member 124 is connected to the first upright plate 122, or to the second upright plate 123, or simultaneously to both the first upright plate 122 and the second upright plate 123. The third elastic portion 1241 and the fourth elastic portion 1242 of the second clamping member 124 can both undergo elastic deformation under external force. After the external force is removed, the third elastic portion 1241 and the fourth elastic portion 1242 can return to their pre-deformation state. Both the third elastic portion 1241 and the fourth elastic portion 1242 are located within the interface 100b. When the optical module is inserted into the interface 100b, the third elastic portion 1241 and the optical module are pressed together, and the fourth elastic portion 1242 and the optical module are pressed together to prevent the optical module from becoming loose.

[0104] In some embodiments, the second clamping member 124 further includes a first connecting portion 1243, a second snap-fit ​​portion 1244, and a third snap-fit ​​portion 1245. The first connecting portion 1243 is located between and connected to the third elastic portion 1241 and the fourth elastic portion 1242. The second snap-fit ​​portion 1244 is connected to the third elastic portion 1241, and the third snap-fit ​​portion 1245 is connected to the fourth elastic portion 1242. A fourth snap-fit ​​hole 122b is provided on the first upright plate 122, and a fifth snap-fit ​​hole 123b is provided on the second upright plate 123. The second snap-fit ​​portion 1244 snaps into the fifth snap-fit ​​hole 123b, and the third snap-fit ​​portion 1245 snaps into the fourth snap-fit ​​hole 122b.

[0105] In some embodiments, a fifth heat dissipation hole 1243a is provided on the first connecting part 1243. The heat in the first interval 121a can be quickly discharged through the fifth heat dissipation hole 1243a, which helps to improve the heat dissipation performance of the optical module cage 100.

[0106] In some embodiments, the second clamping member 124 is formed by bending a metal plate with a certain elasticity, the third elastic portion 1241 protrudes outward toward the side away from the fourth elastic portion 1242, and the fourth elastic portion 1242 protrudes outward toward the side away from the third elastic portion 1241.

[0107] like Figure 6 and Figure 8 As shown, in some embodiments, the horizontal plate assembly 125 includes a first horizontal plate 126 and a second horizontal plate 127. The first horizontal plate 126 has a third heat dissipation hole 126a and is connected to two adjacent vertical plate assemblies 121, or to the vertical plate assembly 121 and the outer frame assembly 110. The second horizontal plate 127 has a fourth heat dissipation hole 127a and is connected to two adjacent vertical plate assemblies 121, or to the vertical plate assembly 121 and the outer frame assembly 110. Along a second direction, a second interval 125a is formed between the second horizontal plate 127 and the first horizontal plate 126, and the third heat dissipation hole 126a, the fourth heat dissipation hole 127a, and the second interval 125a form a heat dissipation channel 100a.

[0108] A second gap 125a exists between the second horizontal plate 127 and the first horizontal plate 126, meaning that the second horizontal plate 127 and the first horizontal plate 126 are spaced apart along a second direction, with a gap between them. A third heat dissipation hole 126a connects to the interface 100b and the second gap 125a, and a fourth heat dissipation hole 127a also connects to the interface 100b and the second gap 125a. Heat generated by the optical module in the interface 100b flows through the third heat dissipation hole 126a or the fourth heat dissipation hole 127a into the second gap 125a, and then flows along the second gap 125a to the outside of the optical module cage 100. Alternatively, cool air from the outside can enter the interface 100b through the second gap 125a, the third heat dissipation hole 126a, and the fourth heat dissipation hole 127a, absorbing the heat from the optical module and allowing for rapid heat dissipation.

[0109] A first horizontal plate 126 located between two adjacent upright plate assemblies 121 is connected to the two adjacent upright plate assemblies 121. A second horizontal plate 127 located between two adjacent upright plate assemblies 121 is connected to the two adjacent upright plate assemblies 121. A second horizontal plate 127 located between an upright plate assembly 121 and an outer frame assembly 110 is connected to the upright plate assembly 121 and the outer frame assembly 110. (The last sentence appears to be a repetition of the previous one and can be omitted.)

[0110] Specifically, in the embodiment where the outer frame assembly 110 includes a first plate 111, a second plate 112, a third plate 113, and a fourth plate 114, and the upright plate assembly 121 includes a first upright plate 122 and a second upright plate 123, the first horizontal plate 126 of the horizontal plate assembly 125 located between two adjacent upright plate assemblies 121 is connected to the two adjacent first upright plates 122 and the second upright plate 123, and the second horizontal plate 127 of the horizontal plate assembly 125 located between two adjacent upright plate assemblies 121 is also connected to the two adjacent first upright plates 122 and the second upright plate 123. The first horizontal plate 126 of the horizontal plate assembly 125 located between the third plate 113 and the upright plate assembly 121 connects the third plate 113 and the corresponding second upright plate 123 of the upright plate assembly 121, and the second horizontal plate 127 of the horizontal plate assembly 125 located between the third plate 113 and the upright plate assembly 121 connects the third plate 113 and the corresponding second upright plate 123 of the upright plate assembly 121. The first horizontal plate 126 of the horizontal plate assembly 125 located between the fourth plate 114 and the vertical plate assembly 121 connects the fourth plate 114 and the first vertical plate 122 of the corresponding vertical plate assembly 121. The second horizontal plate 127 of the horizontal plate assembly 125 located between the fourth plate 114 and the vertical plate assembly 121 connects the fourth plate 114 and the first vertical plate 122 of the corresponding vertical plate assembly 121.

[0111] like Figure 1 , Figure 2, Figure 4 , Figure 11 and Figure 12 As shown, in some embodiments, the cross plate assembly 125 further includes a third clamping member 128, which is mounted on the first cross plate 126 and / or the second cross plate 127. The third clamping member 128 has a fifth elastic portion 1281 and a sixth elastic portion 1282, which are respectively located in two adjacent interfaces 100b along the second direction.

[0112] The third clamping member 128 is connected to the first horizontal plate 126, or the second horizontal plate 127, or both. The fifth elastic portion 1281 and the sixth elastic portion 1282 of the third clamping member 128 can both undergo elastic deformation under external force, and can return to their original state after the external force is removed. Both the fifth elastic portion 1281 and the sixth elastic portion 1282 are located within the interface 100b. When the optical module is inserted into the interface 100b, the fifth elastic portion 1281 and the optical module are pressed together, and the sixth elastic portion 1282 and the optical module are pressed together to prevent the optical module from becoming loose.

[0113] In some embodiments, the third clamping member 128 further includes a second connecting portion 1283, a fourth locking portion 1284, and a fifth locking portion 1285. The second connecting portion 1283 is located between and connected to the fifth elastic portion 1281 and the sixth elastic portion 1282. The fourth locking portion 1284 is connected to the fifth elastic portion 1281, and the fifth locking portion 1285 is connected to the sixth elastic portion 1282. A second locking hole 126b is provided on the first horizontal plate 126, and a third locking hole 127b is provided on the second horizontal plate 127. The fourth locking portion 1284 is engaged in the second locking hole 126b, and the fifth locking portion 1285 is engaged in the third locking hole 127b.

[0114] In some embodiments, the third clamping member 128 is formed by bending a metal plate with a certain elasticity, the sixth elastic portion 1282 protrudes outward toward the side away from the fifth elastic portion 1281, and the fifth elastic portion 1281 protrudes outward toward the side away from the sixth elastic portion 1282.

[0115] In some embodiments, a sixth heat dissipation hole 1283a is provided on the second connecting part 1283. The heat in the second interval 125a can be quickly discharged through the sixth heat dissipation hole 1283a, which helps to improve the heat dissipation performance of the optical module cage 100.

[0116] In some embodiments, the second connecting portion 1283 is also provided with an LED light clearance hole (not shown in the figure). The LED light clearance hole is used to avoid the LED light, so that the LED light can be exposed and observed by the operator. The LED light is used to indicate the working status of the optical module. For example, when the optical module is working, the LED light is on; for example, when the optical module is not working, the LED light is off.

[0117] In some embodiments, along the first direction, the LED light clearance hole is provided on one side of the second connection portion 1283, and the LED light clearance hole is not provided in the middle area of ​​the second connection portion 1283, so as to prevent cables and other objects from blocking the LED light and affecting the operator's observation.

[0118] like Figure 15 As shown, based on the same inventive concept, this application embodiment also provides a switch housing 1000, including a housing 200 and an optical module cage 100. The housing 200 has a receiving cavity for accommodating components and a mounting port 200a communicating with the receiving cavity. The optical module cage 100 is installed in the housing 200 and located inside the mounting port 200. The interface 100b of the optical module cage 100 communicates with the receiving cavity and the outside of the housing 200.

[0119] The heat dissipation device, circuit board, management engine, system controller, switching module, and other components of the switch are installed in the housing cavity, which is used to house these components. The optical module cage 100 is connected to the outer shell 200 and located inside the mounting port 200. After the optical module cage 100 is installed, the interface 100b connects the mounting cavity 110a and the outside of the outer shell 200, so that after the optical module is plugged into the interface 100b, it can be connected to other components in the housing cavity.

[0120] The optical module cage 100 and the outer shell 200 can be connected by means of snap-fit, bolt connection or other methods, which are not limited in this application.

[0121] Since the switch housing 1000 includes the aforementioned optical module cage 100, it naturally possesses all the beneficial effects of the optical module cage 100, which will not be elaborated upon here.

The housing 210, the panel 220, and the management card 230 together form a receiving cavity.

[0125] The management card 230 can be equipped with multiple ports 230a, which can be used to avoid indicator lights, install USB ports, or serve as service ports for switching. The management card 230 is detachable and can be connected via snap-fit ​​or bolts. When the switch requires expansion later, the management card 230 can be replaced with one having different ports 230a to meet the expansion needs, thus simplifying the user experience.

[0126] In some embodiments, the management card 230 and the housing 210 are snap-fitted together and screwed together.

[0127] In some embodiments, the panel 220 is provided with three mounting ports 200a and three optical module cages 100, with the optical module cages 100 and the mounting ports 200 corresponding to each other, and each optical module cage 100 having 32 interfaces 100b.
