Description

Technical Field

[0001] This application relates to the field of communication equipment technology, specifically to a pull-out patch panel and cabinet. Background Technology

[0002] In the field of communication technology, fiber optic distribution frames are typically used to integrate multiple fiber optic connectors to meet the fiber optic connection management needs of large-scale data centers. However, due to the limitations of the internal space layout of fiber optic distribution frames, when pursuing high integration to accommodate more fiber optic connectors, spatial interference can easily occur between adjacent fiber optic connectors during assembly and disassembly. This makes maintenance operations difficult and increases the complexity of cabling management, thus making it difficult for fiber optic distribution frames to effectively simplify cabling while increasing the capacity of fiber optic connectors. Utility Model Content

[0005] A pull-out patch panel according to an embodiment of this application includes a housing, a guide rail structure, and a tray assembly;

[0006] The housing has a wiring cavity;

[0010] The pull-out patch panel according to the embodiments of this application has at least the following beneficial effects: The pull-out patch panel adopts a multi-layer tray structure stacked arrangement, which allows the tray assembly to provide multiple mounting positions, each of which can install a module box, thereby accommodating more fiber optic connectors and helping to increase the fiber optic connector capacity of the pull-out patch panel. At the same time, each layer of the tray structure can independently carry the module box. During wiring and maintenance operations, the tray structure can be pulled out from the patch panel cavity, and the operator can perform fiber optic connection operations on the module box installed on the tray structure from outside the patch panel cavity.

The driving block is provided with a through groove, and the limiting protrusion extends into the through groove.

[0016] The drive block is configured such that when the limiting protrusion is spaced from the end of the through groove along the first direction, the drive block abuts against the spring block, so that the spring block undergoes elastic deformation to avoid the tray guide rail; or, when the limiting protrusion abuts against the end of the through groove along the first direction, the drive block is partially placed in the limiting groove, so that the spring block rebounds.

[0017] According to some embodiments of this application, the module box further includes a box body, a first protrusion and a second protrusion. Along a first direction, the first protrusion and the second protrusion are arranged at intervals. In two adjacent tray guide rails, one is provided with a first pressing groove and the other is provided with a second pressing groove.

[0041] The embodiments of this application are described below with reference to the accompanying drawings:

[0042] refer to Figures 1 to 3According to an embodiment of this application, a pull-out patch panel includes a housing 110, a guide rail structure 210, a tray assembly 300, and a module box 400. The housing 110 has a wiring cavity 111 for accommodating and arranging various wiring components and storing redundant cables. The guide rail structure 210 is located within the wiring cavity 111 and connected to the inner wall of the wiring cavity 111. The guide rail structure 210 has a guide groove 211 extending along a first direction, which can be understood as a horizontal direction. The guide groove 211 provides guidance for the tray structure 310 to be assembled within the wiring cavity 111. The groove wall of the guide groove 211 has a snap-fit ​​groove 212, which is a recessed groove structure formed by indentation from the groove wall of the guide groove 211. The tray assembly 300 is located inside the wiring cavity 111. The tray assembly 300 includes a multi-layer tray structure 310 arranged in layers, such as two, three, or four layers. Part of the tray structure 310 passes through the guide groove 211. The guide groove 211 guides and limits the movement of the tray structure 310. The tray structure 310 can move in the first direction and the opposite direction within the guide groove 211. Each tray structure 310 is provided with a mounting position 320. The shape of the mounting position 320 is adapted to the shape of the module box 400. The module box 400 is installed in the mounting position 320 by plugging and unplugging. The module box 400 is used to install components such as fiber optic connectors to realize the connection and conversion functions of optical fibers.

[0043] The tray structure 310 has a latching part 3123 on the side facing the latching groove 212. The latching part 3123 is an elastic protrusion. The latching part 3123 is placed in the latching groove 212, and a part of the latching part 3123 is exposed outside the latching groove 212, so that the operator can drive the latching part 3123 to generate elastic deformation. The latching part 3123 is configured to abut against the guide rail structure 210 to generate elastic deformation. When the tray structure 310 passes through the guide groove 211 in the first direction, the latching part 3123 first contacts the edge of the guide rail structure 210 and is squeezed. Since the latching part 3123 is an elastic protrusion, it will undergo elastic deformation under the action of the squeezing force to avoid the guide rail structure 210 from being vertically latched into the latching groove 212 in the first direction.

[0044] Alternatively, when it is necessary to pull the tray structure 310 away from the guide rail structure 210 in the reverse direction of the first direction, the operator can press the part of the latching part 3123 exposed in the latching groove 212, so that the latching part 3123 is subjected to driving force to produce elastic deformation and exit the latching groove 212, thereby enabling the tray structure 310 to be pulled away from the guide rail structure 210 in the reverse direction of the first direction.

[0045] In summary, the pull-out patch panel of this application adopts a multi-layer tray structure 310 stacked arrangement, which allows the tray assembly 300 to provide multiple mounting positions 320. Each mounting position 320 can install a module box 400, thereby accommodating more fiber optic connectors and helping to increase the fiber optic connector capacity of the pull-out patch panel. At the same time, each layer of tray structure 310 can independently support the module box 400. During wiring and maintenance operations, the tray structure 310 can be pulled out from the patch panel cavity 111. Operators can perform fiber optic connection operations on the module box 400 installed on the tray structure 310 from outside the patch panel cavity 111. The operating space is larger and the line of sight is clearer. After the wiring is completed, the tray structure 310 is pushed back into the patch panel cavity 111 along the first direction and fixed by the cooperation of the snap-fit ​​part 3123 and the snap-fit ​​slot 212. Compared with direct wiring in the narrow patch panel cavity 111, this operation method helps to simplify the wiring difficulty and improve the wiring efficiency and accuracy.

[0046] refer to Figures 1 to 3 In other embodiments, the pull-out patch panel includes a housing 110, two guide rail structures 210, a tray assembly 300, and a module box 400. The housing 110 also has a wiring cavity 111, with a first direction, a second direction, and a third direction that are mutually perpendicular. The first direction can be a horizontal front-back direction, the second direction can be a horizontal left-right direction, and the third direction can be a vertical up-down direction.

[0047] Along the second direction, the housing 110 has two oppositely arranged sidewalls, both of which are part of the inner wall of the wiring cavity 111. Two guide rail structures 210 are respectively connected to the side of the two sidewalls near the wiring cavity 111. Each guide rail structure 210 is provided with multiple guide grooves 211 extending along the first direction. The guide grooves 211 are arranged sequentially and alternately along the third direction. The spacing between adjacent guide grooves 211 is adapted to the thickness of the tray structure 310, forming a load-bearing structure with the same number of layers as the tray assembly 300. The multi-layer tray structure 310 of the tray assembly 300 is respectively inserted into the corresponding guide grooves 211 of the two guide rail structures 210 on opposite sides.

[0048] Specifically, the left edge of each pallet structure 310 is inserted into a guide groove 211 of the left guide rail structure 210, and the right edge is inserted into the corresponding guide groove 211 of the right guide rail structure 210. The groove wall of the guide groove 211 limits the two sides of the pallet structure 310. Each pallet structure 310 is provided with a snap-fit ​​part 3123 facing the groove wall of the guide groove 211 on both sides. The snap-fit ​​part 3123 is an elastic protrusion. Correspondingly, the groove wall of the guide groove 211 is provided with a snap-fit ​​groove 212 that matches the snap-fit ​​part 3123. The snap-fit ​​parts 3123 on both sides of the pallet structure 310 can be snapped into the snap-fit ​​grooves 212 on both sides respectively, and a part of the snap-fit ​​part 3123 is exposed outside the snap-fit ​​groove 212. The working principle of the latching part 3123 is the same as that of the aforementioned embodiment. When the tray structure 310 enters the guide groove 211 along the first direction, the latching part 3123 abuts against the guide rail structure 210 to generate elastic deformation to avoid it, and then smoothly enters the latching groove 212. When it is necessary to remove it, press the exposed latching part 3123 to make it elastically deform and exit the latching groove 212, and the tray structure 310 can be removed in the opposite direction along the first direction.

[0049] This embodiment employs two guide rail structures 210, with each layer of tray structure 310 engaging with guide grooves 211 on both sides. When the tray structure 310 moves along the first direction or carries the module box 400, the guide grooves 211 on both sides simultaneously provide support and guidance, reducing the tilting or swaying that may occur due to unilateral force on the tray structure 310, thus improving the stability of each layer of tray structure 310 after assembly. Simultaneously, the snap-fit ​​parts 3123 on both sides engage with the snap-fit ​​grooves 212, achieving positioning and fixation from both sides of the tray structure 310. Compared to single-sided snap-fit, this double-sided snap-fit ​​method more effectively restricts the displacement of the tray structure 310 in the second and third directions, making the installation position 320 of the tray structure 310 within the wiring cavity 111 more stable. This reduces the risk of accidental movement of the tray structure 310 due to external vibration or accidental contact, helping to ensure the stability of the fiber optic connection.

[0050] refer to Figures 1 to 3 In some embodiments, along the first direction, the guide groove 211 has two interlocking grooves 212 spaced apart on its groove wall. The tray structure 310 has two interlocking parts 3123 spaced apart on the side facing the interlocking grooves 212. The interlocking parts 3123 are placed in the interlocking grooves 212 in a one-to-one correspondence, that is, each interlocking part 3123 is placed in the corresponding interlocking groove 212. The groove wall on the side of the two interlocking grooves 212 that are close to each other is provided with an interlocking inclined surface 2123. The interlocking inclined surface 2123 is an inclined planar structure. Both interlocking inclined surfaces 2123 extend towards the guide rail structure 210 and are close to the tray structure 310. This direction is consistent with the second direction. The two interlocking inclined surfaces 2123 gradually approach each other from both ends to the middle along the first direction, forming an interlocking groove 212 that is wide at the entrance and narrow inside.

[0051] Specifically, the two snap-fit ​​slots 212 can be divided into a first snap-fit ​​slot 2121 and a second snap-fit ​​slot 2122, and the two snap-fit ​​parts 3123 can be divided into a first snap-fit ​​part 3124 and a second snap-fit ​​part 3125. The first snap-fit ​​part 3124 is placed in the first snap-fit ​​slot 2121, and the second snap-fit ​​part 3125 is placed in the second snap-fit ​​slot 2122. A portion of the second snap-fit ​​part 3125 is exposed in the guide groove 211, which facilitates direct contact and operation by the operator. Both the first snap-fit ​​part 3124 and the second snap-fit ​​part 3125 are elastic protrusions that can deform under external force and return to their original shape after the external force is removed. When assembling the pallet structure 310, the pallet structure 310 is pushed along the first direction to allow it to pass through the guide groove 211. The first engaging part 3124 enters the area of ​​the guide rail structure 210 before the second engaging part 3125. As the pallet structure 310 continues to advance, the first engaging part 3124 first contacts the groove wall of the second engaging slot 2122. Since the first engaging part 3124 has not yet reached the corresponding first engaging slot 2121, it will temporarily enter the second engaging slot 2122. As the pallet structure 310 continues to be pushed, the first engaging part 3124 and the second engaging slot 2122 approach the first engaging part 3125. The first locking part 3124 contacts the locking inclined surface 2123 on one side of the locking groove 2121. The inclination angle of the locking inclined surface 2123 causes the first locking part 3124 to slide along the inclined surface under the action of the thrust, thereby generating elastic deformation and gradually withdrawing from the second locking groove 2122. When the tray structure 310 is pushed to the preset position, the first locking part 3124 just reaches the first locking groove 2121 and bounces into the first locking groove 2121 under the action of its own elastic restoring force. At the same time, the second locking part 3125 also enters the second locking groove 2122, completing the precise cooperation between the two locking parts 3123 and the two locking grooves 212.

[0052] When it is necessary to pull the tray structure 310 away in the reverse direction of the first direction, the operator can press the exposed second locking part 3125 to make the second locking part 3125 elastically deform and exit the second locking groove 2122. At the same time, pull the tray structure 310 outward. The first locking part 3124 will abut against the locking slope 2123 on the side of the first locking groove 2121 near the second locking groove 2122. Under the action of the pulling force, it slides along the locking slope 2123 and generates elastic deformation, thereby exiting the first locking groove 2121. At this time, the tray structure 310 can be smoothly pulled away from the guide rail structure 210.

[0053] Therefore, a matching structure of two snap-fit ​​parts 3123 and two snap-fit ​​slots 212 is adopted. The matching of the double snap-fit ​​positions can more effectively limit the displacement of the tray structure 310 in the first direction, further enhance the overall stability of the tray structure 310 after installation, and ensure the reliability of the optical fiber connection in the module box 400.

[0054] refer to Figures 1 to 3In other embodiments, the portion of the snap-fit ​​part 3123 that snaps into the snap-fit ​​groove 212 is configured as an inclined structure, including but not limited to triangular or trapezoidal shapes. For example, the end of the snap-fit ​​part 3123 that snaps into the snap-fit ​​groove 212 has a triangular protrusion, and one side of the triangle forms an inclined surface facing the snap-fit ​​direction. This inclined surface is adapted to the snap-fit ​​inclined surface 2123 of the snap-fit ​​groove 212. The inclination angle of the inclined surface structure matches the inclination angle of the snap-fit ​​inclined surface 2123 of the snap-fit ​​groove 212, ensuring that the two can fit smoothly when in contact. This helps to reduce the frictional resistance between the snap-fit ​​part 3123 and the snap-fit ​​groove 212, making the assembly and disassembly operations easier and improving assembly efficiency.

[0055] refer to Figures 1 to 3 In some embodiments, the tray structure 310 is provided with a groove 3126 on the side facing the guide rail structure 210. The groove 3126 is a groove structure extending along a first direction. The width of the groove 3126 is adapted to the thickness of the upper groove wall of the snap-fit ​​groove 212. The upper groove wall of the snap-fit ​​groove 212 can be inserted into and placed in the groove 3126. The inner sidewall of the groove 3126 fits against the outer side of the upper groove wall of the snap-fit ​​groove 212, forming a limiting fit along a third direction. The end of the groove 3126 corresponding to the insertion of the upper groove wall of the snap-fit ​​groove 212 is provided with a slope of the groove 3126. The slope of the groove 3126 is an inclined surface extending from the opening end of the groove 3126 inward. Along the first direction, the slope of the groove 3126 gradually extends inward toward the direction away from the lower groove wall of the groove 3126, so that the opening end of the groove 3126 shows a gradually increasing trend, that is, the width of the groove at the opening end is greater than the width of the groove inside.

[0056] When assembling the pallet structure 310, the pallet structure 310 is pushed along the first direction. The upper wall of the locking groove 212 first contacts the inclined surface of the slide groove 3126. As the opening of the slide groove 3126 gradually increases, the upper wall of the locking groove 212 can more easily align with the entrance of the slide groove 3126. As the pallet structure 310 continues to advance, the upper wall of the locking groove 212 slides along the inclined surface of the slide groove 3126, gradually entering the interior of the slide groove 3126 until it is completely placed in the slide groove 3126, completing the mating installation of the slide groove 3126 and the upper wall of the locking groove 212. Thus, the inner wall of the slide groove 3126 forms a constraint on the upper wall of the locking groove 212 along the third direction, limiting the displacement amplitude of the pallet structure 310 in the third direction. When the pallet structure 310 is subjected to external vibration, it can reduce the swaying of the pallet structure 310 along the third direction, which is beneficial to further improve the stability of the pallet structure 310 along the third direction.

[0057] refer to Figures 2 to 5In some embodiments, the tray structure 310 includes a carrier plate 311 and multiple tray rails 312. The carrier plate 311 is a flat structure used to support the module box 400 and the tray rails 312. Each tray rail 312 is connected to the carrier plate 311. Along the second direction, adjacent tray rails 312 are spaced apart, and the spacing is adapted to the width of the module box 400 along the second direction. The upper surface of the carrier plate 311 and the inner sidewalls of the multiple tray rails 312 together enclose the mounting position 320, so that the shape and size of the mounting position 320 match the shape of the module box 400. The module box 400 has a first elastic part 410 and a second elastic part 420 on opposite sides, and both the first elastic part 410 and the second elastic part 420 can undergo elastic deformation under external force.

[0058] When installing the module box 400, align the module box 400 with the entrance of the mounting position 320 and push it into the mounting position 320 in the first direction. The first elastic part 410 and the second elastic part 420 on both sides of the module box 400 contact and are squeezed with the tray guide rails 312 on both sides, generating elastic deformation. As the module box 400 is fully inserted into the mounting position 320, the first elastic part 410 abuts against the inner wall of one side of the tray guide rail 312, and the second elastic part 420 abuts against the inner wall of the other side of the tray guide rail 312. The elastic restoring force generated by the two abuts the module box 400 from both sides and fixes it in the mounting position 320.

[0059] When the module box 400 needs to be removed, the first elastic part 410 and / or the second elastic part 420 are manipulated to deform and disengage from the tray guide rail 312. The module box 400 can then be removed from the mounting position 320 by pulling in the opposite direction of the first direction. When the tray structure 310 moves or is subjected to vibration, the elastic fixing method can reduce the shaking of the module box 400. At the same time, the installation and removal of the module box 400 can be completed manually without the need for additional tools, which helps to simplify the replacement and maintenance process of the module box 400 and improve operational efficiency. In addition, the elastic force of the first elastic part 410 and the second elastic part 420 can also accommodate the small dimensional deviations between the module box 400 and the mounting position 320, enhancing the compatibility of the structure.

[0060] refer to Figures 2 to 5In some embodiments, one of the two adjacent tray guide rails 312 is provided with a first limiting part 3121 and the other is provided with a second limiting part 3122. Along the first direction, the module box 400 includes a first end and a second end opposite to each other. A first elastic part 410 is arranged at the first end and a second elastic part 420 is arranged at the second end. The first limiting part 3121 abuts against the first elastic part 410 and the second limiting part 3122 abuts against the second elastic part 420. Both the first limiting part 3121 and the second limiting part 3122 can adopt a limiting groove structure. The groove of the first limiting part 3121 is opened along the first direction, and the groove of the second limiting part 3122 is opened in the opposite direction to the first direction. The grooves are both tapered structures, that is, the width of the outer side of the groove is greater than the width of the inner side. As it extends into the limiting groove, the groove width gradually decreases, which facilitates the abutment and alignment between the first elastic part 410 and the first limiting part 3121, and between the second elastic part 420 and the second limiting part 3122. The first limiting part 3121 and the first elastic part 410 abut against each other to restrict the module box 400 from moving along the first direction, and the second limiting part 3122 and the second elastic part 420 abut against each other to restrict the module box 400 from moving in the opposite direction to the first direction.

[0061] When the module box 400 needs to be pulled out from the first direction, the first elastic part 410 is driven to deform and disengage from the first limiting part 3121. At this time, the movement of the module box 400 along the first direction is no longer restricted by the first limiting part 3121, and the module box 400 can be pulled out from that direction by pulling it. When the module box 400 needs to be pulled out from the reverse direction of the first direction, the second elastic part 420 is driven to deform and disengage from the second limiting part 3122. The movement of the module box 400 in the reverse direction of the first direction is no longer restricted by the second limiting part 3122, and the module box 400 can be pulled out from that direction by pushing it. Thus, the operator can choose to pull out the module box 400 from either end according to the space of the wiring cavity 111 or the operator's habits, which helps to improve the flexibility of disassembling and assembling the module box 400.

[0062] refer to Figure 3 In some embodiments, along a third direction, the carrier plate 311 is provided with heat dissipation through holes 3111. The heat dissipation through holes 3111 are hole structures that penetrate the upper and lower surfaces of the carrier plate 311. Multiple heat dissipation through holes 3111 can be provided, and the specific number can be matched with the number of mounting positions 320. That is, each mounting position 320 is provided with a corresponding heat dissipation through hole 3111. The shape of the heat dissipation through holes 3111 can be circular, rectangular or other suitable shapes.

[0063] The module box 400 has an interface end, which is the end equipped with an optical fiber interface for plugging and unplugging optical fiber connections. The interface end of the module box 400 extends in the opposite direction of the first direction to the corresponding heat dissipation through hole 3111, and partially covers the heat dissipation through hole 3111. That is, the edge of the interface end extends beyond the edge of the heat dissipation through hole 3111, so that the interface end and the heat dissipation through hole 3111 have a partially overlapping positional relationship. The first direction, the second direction, and the third direction are mutually perpendicular, with the third direction being the vertical direction, so that the multi-layer tray structure 310 is arranged sequentially in the vertical direction.

[0064] Based on this, the uncovered portion of the heat dissipation through-hole 3111 forms a vertically connected channel. When the multi-layer tray structure 310 is stacked, the heat dissipation through-holes 3111 of each layer of carrier plate 311 correspond to each other, allowing air between each layer of tray structure 310 to form convection through the heat dissipation through-holes 3111. Heat can be transferred and diffused to the external environment between layers along a third direction through the heat dissipation through-holes 3111, which helps to improve the heat dissipation efficiency between layers. In addition, the setting of the heat dissipation through-hole 3111 allows the operator to observe the interface end of the lower module box 400 through the heat dissipation through-hole 3111 of the upper carrier plate 311. During assembly or maintenance operations, the operator can directly observe the fiber optic connection status of the lower interface end through the heat dissipation through-hole 3111, which helps to simplify the assembly inspection and troubleshooting process and improve maintenance convenience.

[0065] refer to Figures 3 to 6 In some embodiments, the module box 400 includes a box body 430, and the first elastic part 410 and / or the second elastic part 420 include a spring block 411, a driving block 412 and a limiting protrusion 413. The spring block 411 and the limiting protrusion 413 are both connected to the box body 430. The side of the spring block 411 away from the box body 430 is provided with a limiting groove 4111. The limiting groove 4111 is an inwardly recessed groove structure, such as a triangular groove, and the cross-sectional area of ​​its groove opening is larger than that of its bottom. Along the first direction, the driving block 412 is movably connected to the box body 430. For example, the driving block 412 is provided with a through groove 4121 extending along the first direction, and the box body 430 is provided with a protrusion 4122 adapted to the through groove 4121. The protrusion 4122 is embedded in the through groove 4121 to realize the movable connection between the driving block 412 and the box body 430.

[0066] The limiting protrusion 413 extends into the through groove 4121, and there is a gap between the outer wall of the limiting protrusion 413 and the inner wall of the through groove 4121, allowing the drive block 412 to move relative to the limiting protrusion 413 in the first direction. When it is necessary to make the spring block 411 elastically deform to avoid the tray guide rail 312, the drive block 412 is pulled in the opposite direction of the first direction. At this time, there is a gap between the limiting protrusion 413 and the end of the through groove 4121 in the first direction. The drive block 412 abuts against the spring block 411 and applies pressure. The spring block 411 undergoes elastic deformation due to the pressure and bends towards the box body 430, thereby avoiding the tray guide rail 312.

[0067] When it is necessary for the spring block 411 to rebound, the drive block 412 is pushed along the first direction until the limiting protrusion 413 abuts against the end of the through groove 4121 along the first direction. At this time, a part of the drive block 412 is placed in the limiting groove 4111, so that the spring block 411 rebounds under the action of its own elastic restoring force.

[0068] Therefore, in this application, the deformation and rebound of the spring block 411 can be controlled by moving the drive block 412. The deformation degree of the spring block 411 is more stable, avoiding uneven or excessive deformation that may be caused by manually directly turning the elastic part. This helps protect the spring block 411 and extend its service life. In addition, the operating direction of the drive block 412 is consistent with the pushing and pulling direction of the module box 400, which conforms to operating habits, helps to simplify the operation process, and improves the convenience of disassembling and assembling the module box 400.

[0069] refer to Figure 1 In some embodiments, the module box 400 further includes a box body 430, a first protrusion 440 and a second protrusion 450. Along the first direction, the first protrusion 440 and the second protrusion 450 are arranged at intervals. In the two adjacent tray guide rails 312, one is provided with a first pressing groove 3127 and the other is provided with a second pressing groove 3128. The first pressing groove 3127 and the second pressing groove 3128 are both connected along the first direction. When the module box 400 is pushed in or pulled out along the first direction, the first protrusion 440 can slide along the first pressing groove 3127 and the second protrusion 450 can slide along the second pressing groove 3128, ensuring the smooth installation and disassembly of the module box 400. The first protrusion 440 is connected to one side of the box body 430, and the second protrusion 450 is connected to the opposite side of the box body 430. The first protrusion 440 is located in the first pressing groove 3127, and the second protrusion 450 is located in the second pressing groove 3128. The upper and lower surfaces of the first protrusion 440 are respectively in contact with the upper and lower groove walls of the first pressing groove 3127, and the upper and lower surfaces of the second protrusion 450 are respectively in contact with the upper and lower groove walls of the second pressing groove 3128, so as to restrict the movement of the module box 400 in a third direction and help to further improve the stability of the module box 400 installation.

[0070] It should be noted that the two ends of the first pressing groove 3127 are inclined. As it extends from the opening into the groove, the width of the groove gradually decreases to a size that matches the width of the first protrusion 440. The shape of the second pressing groove 3128 can be the same as that of the first pressing groove 3127, that is, the opening expands outward from both ends along the first direction. Thus, during the installation and disassembly of the module box 400, it can provide guidance for the first protrusion 440 and the second protrusion 450 to enter and exit the pressing groove.

[0071] refer to Figures 6 to 8 In some embodiments, the housing 110 includes a main body 112, a first plate 113, and a second plate 114. The main body 112, the first plate 113, and the second plate 114 enclose a wiring cavity 111. The housing 110 includes an inlet side and an outlet side arranged opposite to each other along a first direction. The first plate 113 is detachably connected to the inlet side, and the second plate 114 is detachably connected to the outlet side. The detachability of the two plates facilitates the installation and removal of the module box 400 by the tray assembly 300 from both ends. When it is necessary to install or remove the module box 400 from the inlet side, the first plate 113 can be removed. Similarly, when it is necessary to operate from the outlet side, the second plate 114 can be removed. When no operation is required, the first plate 113 and the second plate 114 are installed in place, forming a seal around the wiring cavity 111 and protecting the internal components from external dust or impact. Thus, the module box 400 can be installed or removed from both sides, which is beneficial to improving the flexibility of further operations.

[0072] refer to Figure 7 In some embodiments, the wiring cavity 111 includes a wiring sub-cavity 115. The housing 110 has a wiring hole 116 that communicates with the wiring sub-cavity 115. The housing 110, the second plate 114, and the tray assembly 300 enclose the wiring sub-cavity 115. Redundant cables can be stored in the wiring sub-cavity 115, which helps to keep the inside of the wiring cavity 111 neat and orderly.

[0073] refer to Figure 7 In other embodiments, the wiring sub-cavity 115 is provided with a cable tie 117. The cable tie 117 is a long strip-shaped protrusion structure. The number of cable ties 117 can be set to one or more according to the volume of the wiring sub-cavity 115 and the cable storage requirements. The cable tie 117 can fix redundant cables with cable ties, so that the redundant cables are arranged more orderly in the wiring sub-cavity 115.

[0074] refer to Figures 1 to 8According to the embodiments of this application, the cabinet includes the pull-out patch panel in any of the above embodiments. The cabinet also includes a cabinet body, and the cabinet body is provided with multiple spaced mounting beams. The pull-out patch panel is placed on the mounting beams. Multiple pull-out patch panels can be placed in the cabinet body. With the pull-out patch panel ensuring the capacity of fiber optic connectors and simplifying cabling, the cabinet can better adapt to the needs of large-scale data centers.
