Description

Technical Field

[0001] This application belongs to the field of optical fiber equipment technology, and specifically relates to an optical fiber storage box, cable reel and optical fiber panel. Background Technology

[0002] FTTR (Fiber to the Room) smart home networking service leverages the advantages of fiber optic transmission, such as high bandwidth and small size, to replace traditional network cables by laying fiber optic cables to every room, ensuring that every room is covered by Wi-Fi signals. Fiber optic panels are an indispensable and crucial device in the fiber optic signal transmission process, providing fiber optic access ports for optical signal transmission.

[0003] Existing fiber optic panels are typically terminal boxes equipped with fiber optic adapters, fusion splice slots, and fiber optic guards. The fiber optic guards are used to coil fiber optic cables of a limited length. During cable laying, an external fiber optic cable of appropriate length needs to be pre-customized based on the distance between the fiber optic home delivery box and the fiber optic panel. One end of the external cable is laid through a conduit in the wall to the fiber optic panel and connected to one end of the fiber optic adapter via a fusion splice. A heat-fusion tube is fitted over the splice and secured in the fusion splice slot. These fiber optic panels have limited space and cannot accommodate splices with fiber optic connectors at both ends. Furthermore, the cable length they can accommodate is limited, requiring fusion splicing of pigtails to connect the fiber optic home delivery box and the fiber optic adapter. The fusion splicing process is cumbersome and requires specialized fusion splicing equipment, making the cable laying process for existing fiber optic panels quite complicated. Summary of the Invention

[0004] This application provides an optical fiber storage box, cable reel, and optical fiber panel, which to some extent solves the problem of the cumbersome optical cable laying process in the use of existing optical fiber panels.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides an optical fiber storage box, which includes: a base box and a cover; a first cable inlet hole is provided on the bottom plate of the base box, and a first mounting component and at least one second mounting component are provided on the bottom plate, the first mounting component is used for detachably mounting a cable tray, and the second mounting component is used for detachably mounting an optical fiber adapter; the cover is closed on the base box and forms a receiving cavity of the optical fiber storage box with the bottom plate.

[0007] The fiber optic cable receptacle provided in this application has a large accommodating cavity. The bottom plate of the receptacle has a first cable inlet hole, a first mounting component for detachably mounting a cable reel, and a second mounting component for detachably mounting a fiber optic adapter. A relatively long optical cable can be wound on the cable reel, and the length of the cable meets the wiring requirements between the fiber optic cable receptacle and the information box. One end of the optical cable can pass through the first cable inlet hole and connect to the fiber optic home delivery information box. The other end connects to one end of the fiber optic adapter within the accommodating cavity. The other end of the fiber optic adapter provides an optical signal to the optical communication equipment, eliminating the need to pre-measure the distance between the fiber optic cable receptacle and the information box to customize the appropriate cable length. Furthermore, the optical cable wound on the cable reel can be a patch cord with fiber optic connectors at both ends. The fiber optic home delivery information box and the fiber optic adapter can be connected via cable plug-in, thereby providing an optical signal access port for the optical communication equipment, simplifying operation.

[0008] In one possible design, the bottom box also includes a perimeter provided at the edge of the bottom plate, on which at least one second cable entry hole is provided.

[0009] Based on this optional method, the optical cable on the cable reel can not only pass through the first cable inlet hole to exit the optical fiber storage box and be connected to the information box set in other rooms or outdoors through the concealed wiring method, but also pass through the second cable inlet hole to exit the optical fiber storage box and be connected to the information box set in other rooms or outdoors through the exposed wiring method.

[0010] Optionally, a removable filling component is provided at the second cable inlet.

[0011] Based on this optional approach, the second cable inlet can be sealed or partially sealed by a filling component, reducing the amount of external dust entering the fiber optic cable housing cavity through the second cable inlet. When the optical cable needs to pass through the second cable inlet, the filling component at the second cable inlet can be removed by pulling or cutting it, thereby freeing up the second cable inlet for cabling.

[0012] Optionally, the bottom box is provided with a second fixing bracket corresponding to the second cable inlet hole, which is used to fix the optical cable passing through the second cable inlet hole.

[0013] In one possible design, the first mounting component includes a limiting plate or multiple limiting plates spaced apart.

[0014] Optionally, the side wall of the limiting plate is provided with a boss for fixing a cable reel sleeved on at least one limiting plate.

[0015] Based on this optional method, the inner ring wall of the cable reel can be engaged with the outer ring wall of the limiting plate, or the outer ring wall of the cable reel can be engaged with the inner ring wall of the limiting plate. Correspondingly, the boss can be set on the outer ring wall or the inner ring wall of the limiting plate. The boss can increase the friction between the cable reel and the limiting plate, thereby fixing the cable reel on the limiting plate and preventing the cable reel from rotating relative to the limiting plate.

[0016] Optionally, at least one limiting plate is disposed around the first cable inlet hole.

[0017] Optionally, the limiting plate is arc-shaped.

[0018] In one possible design, at least two support posts are also provided on the base plate; the height of the support posts is less than the height of the limiting plate, and the at least two support posts are used to support the cable reel.

[0019] Based on this optional approach, the pad can support the cable reel installed on the first mounting assembly, so that a fiber-carrying space is formed between the bottom of the cable reel and the base plate, so that the optical cable on the cable reel can pass through the fiber-carrying space and pass through the first cable inlet hole, thereby avoiding the cable reel squeezing the optical cable.

[0020] Optionally, the limiting plate is provided with a first fixing frame, which is used to fix the optical cable passing through the first cable inlet hole.

[0021] Based on this optional method, after the optical cable between the optical fiber storage box and the information box is laid, the optical cable passing through the first cable inlet hole can be fixed on the first fixing frame by binding with fasteners such as cable ties and straps to prevent the remaining optical cable on the cable reel from becoming loose.

[0022] In one possible design, the base box is further provided with at least one first baffle, which is located around at least one limiting plate; the at least one first baffle is used to limit the position of the optical cable on the cable reel sleeved on at least one limiting plate.

[0023] Based on this optional method, when the cable reel is placed around the limiting plate, the optical cable on the cable reel is located between the limiting plate and the first baffle. The first baffle can be used to limit the position of the optical cable and prevent the optical cable wrapped on the cable reel from popping out of the optical fiber storage box due to its elasticity.

[0024] Optionally, the first baffle has a first protrusion and / or a first clearance hole on the side wall facing away from the receiving cavity, and the lid has a second clearance hole and / or a second protrusion for engaging with the first protrusion on the side wall, for locking the bottom box and the lid that is closed on the bottom box.

[0025] In one possible design, the second mounting assembly includes: a first side plate and a second side plate disposed opposite to each other; a mounting groove is formed between the first side plate and the second side plate for detachably mounting a fiber optic adapter.

[0026] Optionally, the first side plate has at least one first slot on the side wall facing the second side plate, and the second side plate has at least one second slot on the side wall facing the first side plate; the at least one first slot and the at least one second slot are used to attach at least one lug of the fiber optic adapter.

[0027] Based on this optional method, according to the number and position of the lugs provided on the flange of the fiber optic adapter, a first slot and a second slot adapted to the number and position of the lugs are respectively provided on the side wall of the first side plate and the side wall of the second side plate, so that when the fiber optic adapter is installed in the mounting slot, the lugs engage with the first slot and / or the second slot, thereby fixing the fiber optic adapter in the mounting slot.

[0028] Optionally, the cover is provided with a pressure plate, which is positioned opposite to the mounting groove.

[0029] Based on this optional method, when the cover is placed on the bottom box, the pressure plate can abut against the side of the fiber optic adapter installed in the mounting slot facing the cover, thereby applying pressure to the fiber optic adapter in the height direction of the bottom box to further fix the fiber optic adapter in the mounting slot, and avoiding misalignment between the external port of the fiber optic adapter and the first socket when the fiber optic storage box with the fiber optic adapter installed is installed on the wall.

[0030] In one possible design, at least one first notch is provided on the edge, and a second notch corresponding to the first notch is provided on the side wall of the cover; when the cover is closed on the bottom box, the first notch and the corresponding second notch are connected to form a first socket, and the external port a of the fiber optic adapter installed on the second mounting assembly faces the first socket.

[0031] In one possible design, at least one guide post is provided on the side of the perimeter facing the receiving cavity, and the height of the guide post is greater than the height of the perimeter.

[0032] Based on this optional method, the guide post can guide the inner sidewall of the lid to close the box along the height direction of the guide post, making it easy for the sidewall of the lid to quickly align with the edge of the bottom box.

[0033] Optionally, the guide post has a third protrusion on the side wall facing away from the receiving cavity, and the side wall of the lid has a third clearance hole for engaging with the third protrusion, for locking the bottom box and the lid that is closed on the bottom box.

[0034] In one possible design, a groove is provided on the side wall of the rim facing away from the receiving cavity; when the lid is closed on the bottom box, the side wall of the lid and the groove form an unlocking groove.

[0035] Based on this optional method, when the lid is closed on the bottom box, a tool such as a flathead screwdriver can be inserted into the unlocking slot to unlock the lid and bottom box using the lever principle, thus separating the lid and bottom box.

[0036] Optionally, a second baffle is provided on the side of the perimeter facing the receiving cavity. The side wall of the second baffle facing away from the receiving cavity C is adjacent to the groove, and the height of the second baffle is greater than the height of the perimeter.

[0037] Based on this optional method, if the groove extends through the surrounding edge, when using a tool such as a flathead screwdriver to insert into the unlocking slot to unlock, the end inserted into the unlocking slot can abut against the side wall of the second baffle facing the surrounding edge, thereby providing more support during unlocking and using the lever principle to separate the lid and the bottom box.

[0038] Optionally, the second baffle has a guide groove on the side wall facing away from the receiving cavity, and the guide groove is connected to the groove.

[0039] Based on this optional method, if the groove extends through the surrounding edge, when using a tool such as a flathead screwdriver to insert into the unlocking groove to unlock, the end inserted into the unlocking groove can abut against the side wall of the second baffle facing the surrounding edge, thereby providing more support during unlocking, so as to apply force along the extension direction of the guide groove based on the lever principle, thereby separating the lid and the bottom box.

[0040] Optionally, a fourth clearance hole is provided on the second baffle, and a fourth protrusion is provided on the side wall of the box cover for engaging with the fourth clearance hole.

[0041] In one possible design, the base plate also has at least two mounting holes, through which self-tapping screws or expansion screws can be passed to fix the fiber optic storage box to the wall.

[0042] Secondly, this application provides a cable reel, which includes a cable reel body, a first annular disk and a second annular disk. The cable reel body includes a third annular disk and a fourth annular disk. The inner ring wall of the first annular disk is detachably sleeved on the outer ring wall of the third annular disk, and the inner ring wall of the second annular disk is detachably sleeved on the inner ring wall of the fourth annular disk.

[0043] The inner ring wall of the first annular disk is provided with at least one first connecting plate, and the inner ring wall of the second annular disk is provided with at least one second connecting plate.

[0044] The first annular disk includes an inner annular disk and an outer annular disk located around the inner annular disk. An annular baffle is provided between the inner annular disk and the outer annular disk. A through hole is provided on the annular baffle. A third notch is provided on the side of the outer annular disk away from the third annular disk. A slot is protruding on the inner annular disk. The third notch is connected to the slot through the through hole.

[0045] The cable reel provided in this application has detachable first and second annular disks respectively provided on the outer ring walls of the third and fourth annular disks in the main body of the cable reel. This allows more optical fibers to be wound on the cable reel. During the routing process using the optical cable on the cable reel, the optical cable is continuously consumed from the outside to the inside. After the routing is completed, if the ring width of the third and fourth annular disks is greater than the thickness of the wound optical cable, the first and second annular disks can be removed, thereby reducing the volume of the cable reel and making it easier to install the cable reel on other components.

[0046] In addition, the first end of the optical cable wound on the cable reel can be passed through the third notch, so that the optical fiber connector at the first end can be snapped into the outer ring disk. The optical fiber connector at the second end of the optical cable can also be inserted into the slot, thereby fixing both ends of the optical cable on the first ring disk and preventing the optical cable wound on the cable reel from becoming loose.

[0047] Thirdly, this application provides an optical fiber panel that includes an optical fiber storage box and an optical fiber adapter provided by various possible designs of the first aspect.

[0048] Optionally, the fiber optic panel may also include the cable reel provided in the second aspect above. Attached Figure Description

[0065] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include at least one of that feature.

[0067] In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise expressly and specifically limited.

[0068] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0072] It should also be noted that in the embodiments of this application, the same reference numerals are used to represent the same component or part. For the same part in the embodiments of this application, the reference numerals may only be used to mark one part or component as an example. It should be understood that the reference numerals are also applicable to other identical parts or components.

[0073] FTTR (Fiber to the Room) smart home networking service leverages the advantages of fiber optic transmission, such as high bandwidth and small size. It replaces traditional network cables by laying fiber optic cables to every room, ensuring Wi-Fi coverage in every room. Fiber optic panels are an indispensable component in this process, providing fiber optic access ports for signal transmission. Typically, fiber optic panels are small and thin, usually 86mm, allowing them to blend seamlessly into the interior design when installed on walls, maintaining a harmonious and aesthetically pleasing look.

[0074] There are two types of existing fiber optic panels, such as Figure 1 As shown, one type is an 86 panel equipped with a fiber optic adapter, which can be installed in a junction box on the wall. The junction box has a small capacity and cannot accommodate long fiber optic cables. Therefore, when laying fiber optic cables based on this type of fiber optic panel, it is necessary to pre-customize a pigtail of the appropriate length according to the length of the fiber optic cable conduit between the junction box in the wall and the fiber optic home information box (hereinafter referred to as the information box). The fiber optic connector at one end of the pigtail is plugged into the fiber optic adapter on the 86 panel, and the other end is passed through the conduit and then spliced ​​with another section of pigtail for connection to the information box. The fiber optic cable wiring process is cumbersome.

[0075] refer to Figure 2The diagram shows a structural schematic of the fiber optic panel storage box 10 in the prior art. Another type is a fiber optic panel equipped with a fiber optic adapter 11, a fusion splice slot 12, and multiple fiber-stop teeth 14, where the fiber-stop teeth 14 can be used to coil a jumper of a certain length. During the laying of optical cables, the external optical cable from the information box is laid through a pipe on the wall to the storage box 10, enters the fiber optic storage box 10 through the cable inlet 13, and is connected to one end of the fiber optic adapter 11 by a fusion splice. The fusion splice between the external optical cable and the jumper needs to be fitted with a heat fusion tube and fixed in the fusion splice slot 12. However, this type of fiber optic panel has limited space and cannot accommodate jumpers with fiber optic connectors at both ends. The length of optical cable that can be accommodated is also limited. The information box and the fiber optic adapter can only be connected by fusion splicing pigtails. The fusion splicing process is relatively cumbersome and requires professional fusion splicing equipment, making the connection operation of optical cables in the use of this type of fiber optic panel quite complicated.

[0076] Therefore, to address the cumbersome fiber optic cable laying process in existing fiber optic panels, this application provides a fiber optic cable storage box. This box includes a first mounting component for detachably installing a cable reel and a second mounting component for detachably installing a fiber optic adapter. The box has a large capacity to accommodate a cable reel wound with a relatively long fiber optic cable. One end of the cable connects to the fiber optic adapter, and the other end passes through the first cable inlet hole, exits the box, and is laid to and connected to the information box. Laying the cable using this box eliminates the need to pre-measure the distance between the fiber optic access box and the information box to pre-customize the cable length, making the cable laying process more convenient.

[0077] The fiber optic storage box provided in this application embodiment can be applied to fiber optic panels. For example, such as... Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the overall structure of the fiber optic panel provided in an embodiment of this application. Figure 4 This is an exploded view of the optical fiber panel provided in the embodiment of this application. The optical fiber panel includes an optical fiber storage box 100, a cable reel 200, and an optical fiber adapter 300. The cable reel 200 and the optical fiber adapter 300 are detachably disposed in the receiving cavity C of the optical fiber storage box 100. The cable reel 200 includes a cable reel body 210.

[0078] See Figure 3 and Figure 4The inner port 300b of the fiber optic adapter 300 is located inside the receiving cavity C, while the outer port 300a of the fiber optic adapter 300 protrudes from the fiber optic receiver 100. The outer port 300a is used to connect to optical communication devices such as optical network units (ONUs) or optical network terminals (ONTs), thereby providing optical signals to the optical communication devices. An optical network unit is a device equipped with an optical receiver, an uplink optical transmitter, and multiple bridging amplifiers for network monitoring. An optical network terminal (i.e., an optical modem) is a network device that transmits optical signals through optical fiber media, modulating and demodulating the optical signals into other protocol signals. The optical cable wound on the cable reel 200 can be a patch cord with fiber optic connectors at both ends or a pigtail with a fiber optic connector at only one end. For example, taking a patch cord as an example, the fiber optic connector at one end of the patch cord is used to plug into the internal port 300b of the fiber optic adapter 300, and the fiber optic connector at the other end can pass through the fiber optic storage box 100 and plug into the information box. The information box and the fiber optic adapter can be connected by plugging in the optical cable, thereby providing an access port for optical signals for other optical communication devices, making the operation more convenient.

[0079] Optionally, the fiber optic storage box 100 provided in this application embodiment can be of specification 86.

[0080] The fiber optic storage box 100 and cable reel 200 provided in this application will be described in detail below with reference to specific embodiments.

[0081] Figure 5 This is an exploded view of an optical fiber storage box provided in an embodiment of this application. Figure 6 This is an exploded view of the optical fiber storage box provided in an embodiment of this application. Figure 7 This is a schematic diagram of the bottom box of the optical fiber storage box provided in the embodiments of this application. Figure 8 This is a front view and enlarged view of some structures of the bottom box of the optical fiber storage box provided in the embodiments of this application. Figures 5 to 8 As shown, the optical fiber storage box 100 provided in this embodiment of the application includes a bottom box 110 and a box cover 120.

[0082] The bottom plate 111 of the base box 110 has a first cable inlet hole 1111, and the bottom plate 111 is provided with a first mounting component 130 and at least one second mounting component 140. The first mounting component 130 is used for detachably mounting the cable reel 200, and the second mounting component 140 is used for detachably mounting the fiber optic adapter 300. The cover 120 closes to the bottom box 110 and, together with the bottom plate 111, defines the receiving cavity C of the fiber optic storage box 100, which is used to receive the cable reel 200 and the fiber optic adapter 300.

[0083] It should be noted that, in this embodiment of the application, the cable reel 200 is used to wind the optical cable. For example, the optical cable can be an optical cable pigtail or an optical cable jumper.

[0084] The first cable inlet hole 1111 is used to allow optical cables wound on the cable reel 200 to exit the optical fiber storage box 100 or to allow external optical cables to enter the optical fiber storage box 100. This application does not limit the shape of the first cable inlet hole 1111; the shape of the first cable inlet hole 1111 can be circular, square, fan-shaped, or a combination of multiple shapes. For example, ... Figure 5 As shown, the first cable inlet hole 1111 is a combination of a circular hole and a fan-shaped hole. Furthermore, the diameter of the first cable inlet hole 1111 is larger than the outer diameter of the fiber optic connector, thereby ensuring that the optical cable with the fiber optic connector can pass through the first cable inlet hole 1111.

[0085] like Figure 6 As shown, the bottom box 110 also includes a perimeter 112 disposed on the edge of the bottom plate 111, the perimeter 112 being located on the side of the bottom plate 111 facing the lid 120. The perimeter 112 has at least one first notch 1121, and the side wall of the lid 120 has a second notch 121 corresponding to each first notch 1121. Figure 3 As shown, when the cover 120 is closed on the bottom box 110, each first notch 1121 is connected to the corresponding second notch 121 to form a first socket 160. The number of first sockets 160 is the same as the number of second mounting components 140. The outer port 300a of the fiber optic adapter 300 installed on the second mounting component 140 faces the first socket 160, and the inner port 300b is located in the receiving cavity C.

[0086] The fiber optic cable storage box 100 provided in this embodiment can be installed on a wall and can be connected to a fiber optic cable conduit installed on the wall through the first cable inlet hole 1111 for fiber optic cable entry and exit, thereby realizing a concealed wiring method. Specifically, when the fiber optic cable storage box 100 is installed on the wall, the outer side of the bottom box 110 (i.e., the side of the bottom box 110 facing away from the box cover 120) faces the wall, and the first cable inlet hole 1111 on the bottom plate 111 is connected to the fiber optic cable conduit opened on the wall. If a cable reel 200 is installed on the first mounting assembly 130 and a fiber optic jumper is wound on the cable reel 200, the fiber optic connector at one end of the fiber optic jumper can pass through the first cable inlet hole 1111 into the fiber optic cable conduit and connect to the information box located at the other end of the fiber optic cable conduit. The fiber optic connector at the other end of the fiber optic jumper is used to connect to the inner port 300b of the fiber optic adapter 300. Other fiber optic cables can be connected to the outer port 300a of the fiber optic adapter 300 through the first socket 160.

[0087] Furthermore, the base plate 111 has at least two mounting holes 1114. For example, the fiber optic storage box 100 can be fixedly mounted on the wall by passing self-tapping screws or expansion screws through the mounting holes 1114.

[0088] like Figure 5 and Figure 6 As shown, the first mounting assembly 130 includes one limiting plate 131 or multiple limiting plates 131 spaced apart. Specifically, when the first mounting assembly 130 includes one limiting plate 131, the limiting plate 131 can be semi-circular, thereby forming a semi-enclosed first mounting position. When the first mounting assembly 130 includes at least two limiting plates 131 spaced apart, all the limiting plates 131 can be closed to form the first mounting position.

[0089] The shape and size of the first mounting position are adapted to the shape and size of the cable reel 200. For example, if the cable reel 200 includes a cable reel cylinder and the cable reel 200 is a cylindrical structure, then the shape of the limiting plate 131 can be arc-shaped or circular, thereby forming a cylindrical first mounting position, such as... Figure 7 As shown, if the diameter of the first mounting position is greater than the outer diameter of the cable reel 200, the cable reel 200 can be placed in the first mounting position, so that the outer ring wall of the cable reel 200 is engaged with the inner side wall 131a of the limiting plate 131; if the diameter of the first mounting position is smaller than the diameter of the cable reel body, the cable reel body can be sleeved on the periphery of the limiting plate 131, so that the inner wall of the cable reel body is engaged with the outer side wall 131b of the limiting plate 131.

[0090] Optionally, the side wall of the limiting plate 131 is provided with a boss 132. The boss 132 is used to fix the cable reel 200 sleeved on at least one limiting plate 131. The boss 132 can be located on the inner side wall 131a or the outer side wall 131b of the limiting plate 131 according to the installation position of the cable reel 200 on the limiting plate 131, thereby fixing the cable reel 200 on the limiting plate 131 and preventing the cable reel 200 from rotating relative to the limiting plate 131. For example, if the cable reel cylinder 213 of the cable reel 200 is sleeved on the periphery of the limiting plate 131, such as Figure 7 As shown, the boss 132 is correspondingly disposed on the outer side wall 131b of the limiting plate 131; if the cable reel 200 is placed in the first mounting position, the boss 132 is correspondingly disposed on the inner side wall 131a of the limiting plate 131.

[0091] For example, the width of the boss 132 can be 1mm to 2mm, where the width is the relative distance between the side of the boss 132 away from the limiting plate 131 and the side closer to the limiting plate.

[0092] In one example, the first cable inlet 1111 can also be located outside the limiting plate 131, away from it. In another example, if the first cable inlet 1111 is circular or square, the limiting plate 131 can be located around the first cable inlet 1111, and the optical cable on the cable reel 200 sleeved around the limiting plate 131 can pass through the first cable inlet 1111 through the gap between two adjacent limiting plates 131; Figures 5 to 8 As shown, if the first cable inlet 1111 includes a connected circular hole and a fan-shaped hole, then the limiting plate 131 can be located around the circular hole and the fan-shaped hole extends to the outside of the limiting plate 131. The cable reel 200 sleeved around the limiting plate 131 will not block the fan-shaped hole, so that the optical cable on the cable reel 200 can pass through the fan-shaped hole and exit the optical fiber storage box 100.

[0093] Based on the above example, to prevent the cable reel 200 from pressing against the optical cable passing through the first cable inlet 1111 when it is installed on the first mounting assembly 130, such as... Figure 6 and Figure 7 As shown, at least two pads 150 can be provided on the base plate 111. The height of the pads 150 is less than the height of the limiting plate 131. When the cable reel 200 is installed on the first mounting assembly 130, the pads 150 are used to support the cable reel 200, so that a fiber-carrying space is formed between the bottom of the cable reel 200 and the base plate 111, so that the optical cable on the cable reel 200 passes through the fiber-carrying space and passes through the first cable inlet hole 1111, thereby preventing the cable reel 200 from squeezing the optical cable.

[0094] Optionally, the limiting plate 131 is provided with a first fixing frame 133, which is used to fix the optical cable passing through the first cable inlet hole 1111. The optical cable passing through the first cable inlet hole 1111 can be the optical cable on the cable reel 200, or it can be other optical cables that enter the receiving cavity C from the first cable inlet hole 1111.

[0095] In one example, the first fixing frame 133 can be a bracket protruding from the limiting plate 131. It can be fixed to the first fixing frame 133 by binding with fasteners such as cable ties or straps, or by wrapping the optical cable around the first fixing frame 133.

[0096] In another example, such as Figure 7 As shown, a first binding hole 1311 and a second binding hole 1312 are provided on the limiting plate 131, thereby forming a first fixing frame 133 between the first binding hole 1311 and the second binding hole 1312. The optical cable passing through the first cable inlet hole 1111 can be fixed on the first fixing frame 133 by passing the first binding hole 1311 and the second binding hole 1312 through the cable tie, strap or other fixing components.

[0097] Optionally, such as Figure 6 and Figure 7 As shown, the bottom box 110 is also provided with at least one first baffle 170, which is located around the limiting plate 131. If the cable reel 200 is fitted around the limiting plate 131, the optical cable on the cable reel 200 is located between the limiting plate 131 and the first baffle 170. The first baffle 170 can be used to limit the position of the optical cable and prevent the optical cable wrapped on the cable reel 200 from popping out of the optical fiber storage box 100 due to its elasticity.

[0098] In this embodiment, the first baffle 170 can be disposed at the end of the perimeter 112 away from the bottom plate 111, or it can be disposed on the inner side of the perimeter 112 facing the receiving cavity C, or it can be disposed on the side of the bottom plate 111 facing the lid 120.

[0099] For example, assuming the fiber optic storage box 100 provided in this application embodiment has a specification of 86 boxes, the base plate 111 is square, and the surrounding edges 112 are distributed in a square shape, a first baffle 170 can be provided at the end of the surrounding edges 112 distributed in each direction away from the base plate 111, or multiple first baffles 170 can be distributed at intervals. Alternatively, a first baffle 170 can be provided at the end of the surrounding edges 112 distributed in some directions away from the base plate 111, or multiple first baffles 170 can be distributed at intervals. For example, as Figure 6 and Figure 7 As shown, at least one first baffle 170 is provided at the end of the perimeter 112 distributed in two directions closer to the limiting plate 131 that is away from the bottom plate 111. Specifically, one first baffle 170 is provided on the perimeter 112 distributed in one direction, and two first baffles 170 are provided at intervals on the perimeter 112 distributed in the other direction.

[0100] Furthermore, the thickness of the first baffle 170 is less than the thickness of the perimeter 112, where the thickness refers to the relative distance between the sidewall away from the receiving cavity C and the sidewall facing the receiving cavity C. If the first baffle 170 is located at the end of the perimeter 112 away from the bottom plate 111, the sum of the heights of the first baffle 170 and the perimeter 112 is less than the height of the receiving cavity C, but greater than the sum of the heights of the cable reel 200 and the pad 150. If the first baffle 170 is located on the inner side of the perimeter 112 facing the receiving cavity C, or on the side of the bottom plate 111 facing the cover 120, the height of the first baffle 170 is less than the height of the receiving cavity C, but greater than the sum of the heights of the cable reel 200 and the pad 150. The height of the receiving cavity C is the relative distance between the side of the bottom plate 111 facing the lid 120 and the side of the lid 120 facing the bottom plate 111. The height of the first baffle 170 and the height of the surrounding edge 112 are the relative distances between the end facing the bottom plate 111 and the end facing the lid 120.

[0101] like Figure 6 and Figure 7As shown, at least one or more of the first baffles 170 have a first protrusion 171 and / or a first clearance hole 172 on the side wall facing away from the receiving cavity C. The side wall of the lid 120 has a second clearance hole 122 corresponding to the first protrusion 171 and / or a second protrusion 123 corresponding to the first clearance hole 172. When the lid 120 is placed on the bottom box 110, the first protrusion 171 engages with the second clearance hole 122, and the first clearance hole 172 engages with the second protrusion 123, thereby securing the lid 120 to the bottom box 110.

[0102] In another embodiment, such as Figures 5 to 8 As shown, at least one second cable inlet hole 1122 is also provided on the perimeter 112.

[0103] It is understood that the fiber optic storage box 100 provided in this application embodiment can not only connect to the optical cable duct installed on the wall through the first cable inlet 1111 to realize the concealed wiring method, but also realize the exposed wiring method through the second cable inlet 1122. For example, when the fiber optic storage box 100 is installed on the wall, if the first mounting component 130 is equipped with a cable reel 200 and the cable reel 200 is wrapped with an optical cable jumper, one end of the optical cable jumper can pass through the second cable inlet 1122 to exit the fiber optic storage box 100 and connect to the information box set in another room or outdoors through the exposed wiring method. The optical cable between the fiber optic storage box 100 and the information box is exposed on the wall, and the optical fiber connector at the other end of the optical cable jumper is connected to the inner port 300b of the optical fiber adapter 300.

[0104] This application does not limit the number or location of the second cable inlet holes 1122. Optionally, such as Figure 6 and Figure 8 As shown, the perimeter 112 is squarely distributed, and one or more second cable inlet holes 1122 can be opened on the perimeter 112 distributed in each direction, so that the optical cable in the cable tray 200 installed on the first mounting assembly 130 can pass through the second cable inlet hole 1122 in any direction to exit the optical fiber storage box 100 for routing.

[0105] Optionally, refer to Figure 8The enlarged view of the partial structure B on the bottom box 110 shown shows that each second cable inlet hole 1122 is provided with a removable filling component 113. In this way, the second cable inlet hole 1122 can be closed or partially closed by the filling component 113, reducing the amount of external dust entering the receiving cavity C of the fiber optic storage box 100 from the second cable inlet hole 1122. When it is necessary for the optical cable in the cable tray 200 to pass out of the fiber optic storage box 100 from one direction for routing, or when it is necessary for other optical cables to enter the fiber optic storage box 100 from one direction, the filling component 113 provided at the second cable inlet hole 1122 in the corresponding direction can be removed, thereby making the second cable inlet hole 1122 available.

[0106] Optionally, such as Figure 8 As shown, the filling component 113 includes filling posts 1131. Each side of the filling post 1131 facing the perimeter 112 is connected to the perimeter 112 via one or more connecting posts 1132. The connection point between the filling component 113 and the perimeter 112 has a small area, allowing the filling component 113 to be manually pulled out of the second cable inlet 1122, or the connecting posts 1132 to be cut off using scissors or other cutting tools, thereby making way for the second cable inlet 1122.

[0107] Furthermore, the bottom box 110 is provided with a second fixing bracket 1112 corresponding to the second cable inlet hole 1122. The second fixing bracket 1112 is used to fix the optical cable passing through the second cable inlet hole 1122. The second fixing bracket 1112 is arranged on the bottom box 110 adjacent to the second cable inlet hole 1122.

[0108] In one example, the second fixing frame 1112 can be a bracket protruding from the inner side of the perimeter 112 facing the cavity C or the base plate 111. It can be fixed by binding with fasteners such as cable ties or straps, or by wrapping the optical cable around the second fixing frame 1112 to fix the optical cable passing through the second cable inlet hole 1122.

[0109] In another example, such as Figure 7 As shown, the base plate 111 has a third binding hole 1113 corresponding to each second cable inlet hole 1122, and the third binding hole 1113 is connected to the corresponding second cable inlet hole 1122. The second fixing bracket 1112 is located at the opening of the third binding hole 1113 facing the cover 120. The optical cable passing through the second cable inlet hole 1122 can be fixed on the second fixing bracket 1112 by passing through the third binding hole 1113 with a cable tie, strap or other fixing component.

[0110] like Figures 5 to 7As shown, the second mounting assembly 140 includes a first side plate 141 and a second side plate 142 disposed opposite to each other on the base plate 111. A mounting groove 143 adapted to the fiber optic adapter 300 is formed between the first side plate 141 and the second side plate 142 for detachably mounting the fiber optic adapter 300. One end of the mounting groove 143 is aligned with a first notch 1121 opened on the perimeter 112, and the other end is located in the receiving cavity C, such that the outer port 300a of the fiber optic adapter 300 installed in the mounting groove 143 faces the first notch 1121, and the inner port 300b is located inside the receiving cavity C.

[0111] It should be noted that the fiber optic storage box 100 provided in this application can be equipped with multiple second installation components 140 to install multiple fiber optic adapters 300, thereby providing more access ports for the optical cable through the external ports 300a of the multiple fiber optic adapters 300, and thus providing optical signals for more optical communication devices such as optical network units (ONUs) or optical network terminals (ONTs).

[0112] Furthermore, the fiber optic adapter 300 is generally provided with a flange 310, and different types of fiber optic adapters 300 have different numbers of lugs 3101 on the flange 310. Depending on the number and position of the lugs 3101 on the fiber optic adapter 300, slots that fit the lugs 3101 of the fiber optic adapter 300 can be provided on the first side plate 141 and the second side plate 142. When the lugs 3101 of the fiber optic adapter 300 are engaged in the slots, the fiber optic adapter 300 can be fixed in the mounting slot 143.

[0113] For example, such as Figures 5 to 7 As shown, the second mounting component 140 provided in this application can be adapted to an optical fiber adapter 300 having a single lug 3101 or two lugs symmetrically arranged. Specifically, at least one first slot 1411 is spaced apart on the side wall of the second side plate 142 facing the first side plate 141, and at least one second slot 1421 is spaced apart on the side wall of the second side plate 142 facing the first side plate 141. The at least one first slot 1411 and the at least one second slot 1421 are used to engage at least one lug 3101 of the optical fiber adapter 300. One of the at least one first slot 1411 and one of the at least one second slot 1421 are symmetrically arranged.

[0114] Optionally, the cover 120 is provided with a pressure plate 126, and the pressure plate 126 is arranged opposite to the mounting groove 143. When the cover 120 is placed on the bottom box 110, the pressure plate 126 can abut against the side of the fiber optic adapter 300 installed in the mounting groove 143 facing the cover 120, thereby further fixing the fiber optic adapter 300 in the mounting groove 143. This prevents the external port 300a of the fiber optic adapter 300 from being misaligned with the first socket 160 when the fiber optic storage box 100 with the fiber optic adapter 300 installed is fixed to the wall.

[0115] Optionally, such as Figure 5 and Figure 7 As shown, the first side plate 141 can be disposed adjacent to the side of the perimeter 112 facing the receiving cavity C. The height of the first side plate 141 is greater than the height of the perimeter 112. A fifth protrusion 1413 is provided on the side wall of the first side plate 141 facing away from the receiving cavity C. Correspondingly, a hook 127 is provided on the side wall of the lid 120 facing the receiving cavity C. When the lid 120 is placed on the bottom box 110, the hook 127 engages with the fifth protrusion 1413, thereby locking the lid 120 and the bottom box 110. Furthermore, the first side plate 141 can be tightly attached to the side of the perimeter 112 facing the receiving cavity C.

[0116] Furthermore, such as Figure 5 and Figure 7 As shown, a third slot 1412 is provided on the side wall of the first side plate 141 facing away from the receiving cavity C. A fifth protrusion 1413 is provided on the side end of the third slot 1412 away from the bottom plate 111. When the hook 127 is engaged with the fifth protrusion 1413, the end of the hook 127 near the bottom plate 111 is located in the third slot 1412.

[0117] Based on the above example, the fiber optic storage box 100 provided in this application also has at least one guide post 180 on the side of the perimeter 112 facing the receiving cavity C, and the height of the guide post 180 is greater than the height of the perimeter 112. This application does not limit the number of guide posts 180; for example, such as... Figures 5 to 7 As shown, the base box 110 has a square structure and four inner corners. A guide post 180 can be set at each inner corner. When the lid 120 is placed on the base box 110, the guide post 180 guides the inner side wall of the lid 120 to close along the height direction of the guide post 180, so that the side wall of the lid 120 can be quickly aligned with the edge 112 of the base box 110 when closing.

[0118] Optionally, such as Figure 5As shown, one or more guide posts 180 of the fiber optic storage box 100 have a third protrusion 181 on the side wall facing away from the receiving cavity C, and a third clearance hole 124 is provided on the side wall of the box cover 120. When the box cover 120 is placed on the bottom box 110, the third protrusion 181 and the third clearance hole 124 are engaged, thereby locking the box cover 120 and the bottom box 110.

[0119] Furthermore, the fiber optic storage box 100 provided in this application is also provided with an unlocking structure, which is used to unlock the locked box cover 120 and the bottom box 110. For example... Figure 3 and Figure 6 As shown, a groove 1123 is provided on the side wall of the perimeter 112 facing away from the receiving cavity C. When the lid 120 is closed on the bottom box 110, the side wall of the lid 120 and the groove 1123 form an unlocking groove 114. Tools such as a flathead screwdriver can be inserted into the unlocking groove 114 to unlock the lid 120 and the bottom box 110 using the lever principle, so that the lid 120 and the bottom box 110 are separated.

[0120] Optionally, the bottom wall of the groove 1123 facing the lid 120 is not perpendicular to the side wall of the rim 112 facing the receiving cavity C. That is, the end of the bottom wall of the groove 1123 facing the lid 120 near the receiving cavity C can be inclined toward the base plate 111 relative to the end away from the receiving cavity C, or the end of the bottom wall of the groove 1123 facing the lid 120 away from the receiving cavity C can be inclined toward the base plate 111 relative to the end near the receiving cavity C.

[0121] In one example, if the groove 1123 does not penetrate the edge 112, when using a tool such as a flathead screwdriver to unlock the box, the end of the tool inserted into the unlocking groove 114 can abut against the edge 112, thereby providing more support during unlocking and using the lever principle to separate the lid 120 from the bottom box 110.

[0122] In another example, if the groove 1123 extends through the perimeter 112, a second baffle 190 can be provided on the side of the perimeter 112 facing the receiving cavity C. The side wall of the second baffle 190 facing away from the receiving cavity C is adjacent to the groove 1123, and the height of the second baffle 190 is greater than the height of the perimeter 112. Then, when using an unlocking tool such as a flathead screwdriver to unlock the box by inserting it into the unlocking slot 114, one end of the unlocking tool inserted into the unlocking slot 114 can abut against the side wall of the second baffle 190 facing the perimeter 112, thereby providing more support during unlocking to separate the lid 120 and the bottom box 110 using the lever principle.

[0123] It should be noted that the second baffle 190 can be arranged at a certain interval on the side of the perimeter 112 facing the receiving cavity C, or the second baffle 190 can be arranged without gaps on the side of the perimeter 112 facing the receiving cavity C.

[0124] Optionally, a guide groove 191 is provided on the side wall of the second baffle 190 facing away from the receiving cavity C (i.e., the side wall facing the perimeter 112), and the guide groove 191 extends along the height direction of the second baffle 190. Figure 6 As shown, when the second baffle 190 is set without gap on the side of the perimeter 112 facing the receiving cavity C, the guide groove 191 is connected to the groove 1123. When an unlocking tool such as a flathead screwdriver is inserted into the unlocking groove 114 to unlock, the end of the unlocking tool inserted into the guide groove 191 through the unlocking groove 114 can abut against the side wall of the second baffle 190 facing the perimeter 112, thereby providing more support during unlocking, so as to apply force along the direction of the guide groove 191 based on the lever principle, thereby separating the cover 120 and the bottom box 110.

[0125] Optionally, the second baffle 190 is provided with a fourth clearance hole 192, and the side wall of the cover 120 is provided with a fourth protrusion 125. When the cover 120 is closed on the bottom box 110, the fourth protrusion 125 can engage with the fourth clearance hole 192 to further lock the cover 120 and the bottom box 110.

[0126] This application embodiment also provides a cable reel 200, which can be used to install on the first mounting component 130 of the optical fiber storage box 100 provided in the foregoing embodiment. Figure 9 This is a schematic diagram of the structure of the cable reel 200 provided in the embodiments of this application. Figure 8 This is an exploded structural diagram of the cable reel 200 provided in an embodiment of this application. Figure 9 and Figure 10 As shown, the cable reel 200 includes a cable reel body 210, a first annular disk 220, and a second annular disk 230.

[0127] The cable reel body 210 includes a third annular disk 211, a fourth annular disk 212, and a cable reel cylinder 213. The outer wall of the cable reel cylinder 213 is used to wind optical cables with fiber optic connectors. The inner ring wall of the first annular disk 220 is detachably fitted onto the outer ring wall of the third annular disk 211, and the inner ring wall of the second annular disk 230 is detachably fitted onto the outer ring wall of the fourth annular disk 212. The cable reel cylinder 213 is disposed between the third annular disk 211 and the fourth annular disk 212, and the first insertion hole 2111 of the third annular disk 211 is connected to the second insertion hole 2121 of the fourth annular disk 212 through the cable reel cylinder 213.

[0128] Optionally, such as Figure 10As shown, the inner ring wall of the first annular disk 220 is provided with at least one first connecting plate 240, and the inner ring wall of the second annular disk 230 is provided with at least one second connecting plate 250. The inner ring wall of the first annular disk 220 is connected to the outer ring wall of the third annular disk 211 through the first connecting plate 240, and the inner ring wall of the second annular disk 230 is connected to the outer ring wall of the fourth annular disk 212 through the second connecting plate 250. The first annular disk 220 and the second annular disk 230 can be manually pulled away from the third annular disk 211 and the fourth annular disk 212, respectively, or the first connecting plate 240 and the second connecting plate 250 can be cut off using scissors or other cutting tools, so that the third annular disk 211 and the fourth annular disk 212 are separated from the first annular disk 220 and the second annular disk 230, respectively.

[0129] Optionally, such as Figure 10 As shown, the first annular disk 220 includes an inner annular disk 221 and an outer annular disk 222 located around the inner annular disk 221. A first annular baffle 260 is provided between the inner annular disk 221 and the outer annular disk 222. The first annular baffle 260 has a through hole 261. The outer annular disk 222 has a third notch 2221 at its side end away from the third annular disk 211. The inner annular disk 221 has a protruding slot 2211. The third notch 2221 communicates with the slot 2211 through the through hole 261. A second annular baffle 2201 is provided on the outer annular wall of the first annular disk 220, and the second annular baffle 2201 is arranged parallel to the first annular baffle 260.

[0130] For optical cables with fiber optic connectors at both ends wound on the cable reel 200, the first end of the optical cable can be passed through the third notch 2221 so that the fiber optic connector at the first end is snapped into the outer annular disk 222. The second end of the optical cable can be passed through the cable reel cylinder 213 and the fiber optic connector at the second end can be inserted into the slot 2211, thereby fixing both ends of the optical cable on the first annular disk 220 and preventing the optical cable wound on the cable reel 200 from becoming loose.

[0131] It should be noted that during the process of routing the optical cable on the cable reel 200, the optical cable is continuously consumed from the outside to the inside. After the routing is completed, if the ring width of the third annular disk 211 and the fourth annular disk 212 is greater than the thickness of the optical cable wound on the cable reel body 213, the first annular disk 220 and the second annular disk 230 can be disassembled, thereby reducing the volume of the cable reel 200 and making it easier for the cable reel body 210 to be installed on the first mounting component 130 in the optical fiber storage box 100 provided in the above embodiment.

[0132] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
