Description

[0001] This application claims priority to Chinese Patent Application No. 202210797978.X, filed with the China National Intellectual Property Administration on July 6, 2022, entitled “FIBER RECEPTION BOX, CABLE STORAGE AND FIBER PLATE,” which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] This application relates to the field of fiber device technologies and, more particularly, to a fiber receiving box, a cable tray, and a fiber plate. BACKGROUND

[0003] Because fiber has advantages such as wide transmission bandwidth and small size, in an FTTR (Fiber to the Room) smart home network service, fiber replaces traditional network cables, and an optical cable is laid in each room, allowing every room to be covered by a Wi-Fi signal. A fiber plate is an indispensable and important device in fiber signal transmission and is configured to provide an optical fiber access port for optical signal transmission.

[0004] An existing fiber board is usually a termination box equipped with a fiber adapter, a fiber splice seat, and a fiber stopper. The fiber stopper can be configured to wind a fiber of a limited length. In an optical cable laying process, an external optical cable of an appropriate length must be customized in advance based on a distance between a fiber to the home information box and the fiber board. One end of the external optical cable is laid on the fiber board through a pipeline on a wall and is connected to one end of the fiber adapter by a spliced ​​fiber patch cord. A splice point between the external optical cable and the fiber patch cord must be covered with a hot-melt tube and fixed in the fiber splice seat.Such a fiber optic board has limited space, cannot accommodate a fiber optic patch cord with both ends equipped with optical fiber connectors, can accommodate an optical cable of limited length, and can only be connected to the fiber optic adapter and the home information box by splicing a drop cable. The splicing process is cumbersome and requires a professional splicing device. Consequently, the installation process for optical cables is cumbersome when using the existing fiber optic board. SUMMARY

For like parts in embodiments of this application, only a part or component marked with a reference number may be used as an example in the figure. It is understood that the reference number is also applicable to another like part or component.

[0058] In FTTR (Fiber to the Room, Fiber to the Room) smart home networking, fiber optics replace traditional network cables with advantages such as wide transmission bandwidth and small size. Fiber optic cables are laid in each room, allowing Wi-Fi signal coverage throughout the entire network. Fiber optic cables are an essential and important device in fiber optic signal transmission, providing access to optical fibers for optical signal transmission. Fiber optic cables are typically small and thin, measuring approximately 86 x 86 mm. Therefore, when installed on a wall, fiber optic cables can be better integrated into the home improvement environment, keeping the home improvement environment coordinated and aesthetically pleasing.

[0059] There are two types of existing fiberboard. As in Fig. One type, shown in Figure 1, is an 86 x 86 mm plate equipped with a fiber adapter. The 86 x 86 mm plate can be installed on a cassette in a wall. The cassette has a small accommodation space and cannot accommodate a long optical cable. Therefore, in the process of laying an optical cable based on such a fiber plate, a drop cable of an appropriate length must be customized in advance based on the length of an optical cable pipeline between the cassette in the wall and a fiber to the home information box (hereinafter referred to as the information box). A fiber connector at one end of the drop cable is plugged into the fiber adapter on the 86 x 86 mm plate. The other end is spliced ​​with another drop cable after passing through the pipeline and is configured to be connected to the information box.The optical cable cabling process is cumbersome.

[0060] Fig. Figure 2 is a diagram of the structure of a fiberboard receptacle box 10 in conventional technology. Another type is a fiberboard equipped with a fiber adapter 11, a fiber splice seat 12, and a plurality of fiber stop teeth 14. The fiber stop tooth 14 can be configured to be wound with a fiber patch cord of a specific length. In an optical cable laying process, an external optical cable connected from an information box is laid into the receptacle box 10 through a pipeline on a wall, enters the fiber receptacle box 10 through a cable insertion hole 13 provided on the receptacle box 10, and is plug-connected to one end of the fiber adapter 11 by a spliced ​​fiber patch cord. A splice point between the external optical cable and the fiber patch cord must be covered with a hot-melt tube and fixed in the fiber splice seat 12.However, such a fiber board has limited space, cannot accommodate a fiber patch cord with both ends equipped with optical fiber connectors, can accommodate an optical cable of limited length, and can only be connected to the information box and the fiber adapter by splicing a connecting cable. The splicing process is cumbersome and requires a professional splicing device. Consequently, the optical cable connection process is cumbersome when using such a fiber board.

[0061] Therefore, to address a problem that an optical cable laying process in an existing fiber optic cable utilization process is cumbersome, this application provides a fiber accommodation box. A first installation assembly configured to detachably install a cable tray and a second installation assembly configured to detachably install a fiber adapter are arranged in the fiber accommodation box. The fiber accommodation box has a large accommodation space and can accommodate a cable tray wound with an optical cable having a long length. One end of the optical cable is connected to the fiber adapter, and the other end can penetrate from the fiber accommodation box through a first cable insertion hole, is laid in an information box, and is connected to the information box.When the optical cable is laid using the fiber reception box, a distance between a fiber to the home information box and the fiber reception box does not need to be measured in advance to adjust the optical cable with an appropriate length in advance, so that an optical cable laying process becomes more convenient.

[0062] The fiber receiving box provided in embodiments of this application can be used in a fiberboard. For example, Fig. 3 is a diagram of an overall structure of a fiberboard according to an embodiment of this application. Fig. 4 is an exploded diagram of a fiberboard according to an embodiment of this application. The fiberboard includes a fiber receiving box 100, a cable tray 200, and a fiber adapter 300. The cable tray 200 and the fiber adapter 300 are detachably disposed in a receptacle C of the fiber receiving box 100. The cable tray 200 includes a cable tray body 210.

[0063] As in Fig. 3 and Fig. As shown in Figure 4, an internal connector 300b of the fiber adapter 300 is located in the receptacle C, and an external connector 300a of the fiber adapter 300 is exposed from the fiber receptacle box 100. The external connector 300a is configured to be connected to an optical communication device such as an optical network unit (ONU) or an optical network terminal (ONT) to provide an optical signal to the optical communication device. The optical network unit is a device provided with an optical receiver, an optical uplink transmitter, and a plurality of bridge amplifiers for network monitoring, and the optical network terminal (i.e., an optical modem) is a network device that transmits an optical signal through an optical fiber medium to modulate and demodulate the optical signal into a signal of a different protocol.An optical cable wound on the cable tray 200 may be a fiber patch cable whose two ends are both provided with optical fiber connectors, or a drop cable whose only one end is provided with an optical fiber connector. For example, the fiber patch cable is used as an example. An optical fiber connector at one end of the fiber patch cable is configured to be plug-connected to the internal terminal 300b of the fiber adapter 300 through the optical fiber connector, and an optical fiber connector at the other end can penetrate from the fiber receiving box 100 and is plug-connected to an information box. The information box and the fiber adapter can be connected by plugging the optical cable, thus providing an optical signal access port for another optical communication device and making operation more convenient.

[0064] Optionally, a specification of the fiber accommodation box 100 provided in this embodiment of this application may be 86 x 86 mm.

[0065] In the following, the fiber receiving box 100 and the cable tray 200 provided in this application are described in detail using specific embodiments.

Fig. 6 is a diagram of an exploded structure of a fiber accommodation box from another perspective according to an embodiment of this application. Fig. 7 is a diagram of a structure of a box bottom of a fiber accommodation box according to an embodiment of this application. Fig. 8 is a main view of a box bottom of a fiber receiving box and an enlarged view of a partial structure according to an embodiment of this application. As shown in Fig. 5 to Fig. 8, a fiber receiving box 100 provided in this embodiment of this application includes a box bottom 110 and a box cover 120.

The first installation assembly 130 is configured to removably install a cable tray 200, and the second installation assembly 140 is configured to removably install a fiber adapter 300. The box cover 120 covers the box base 110 and defines a receptacle C of the fiber receptacle box 100 with the bottom plate 111. The receptacle C is configured to receive the cable tray 200 and the fiber adapter 300.

[0068] It should be noted that in this embodiment of this application, the cable tray 200 is configured to be wound with an optical cable. For example, the optical cable may be a drop cable of the optical cable or a fiber patch cable of the optical cable.

[0069] The first cable insertion hole 1111 is configured to: allow the optical cable wound on the cable tray 200 to enter from the fiber accommodation box 100, or allow an external optical cable to enter the fiber accommodation box 100. A shape of the first cable insertion hole 1111 is not limited in this application. The shape of the first cable insertion hole 1111 may be a circle, a square, a sector, or a combination of a variety of shapes. For example, as shown in Fig. As shown in Figure 5, the shape of the first cable insertion hole 1111 includes a circular hole and a sector hole that communicate with each other. Furthermore, a hole diameter of the first cable insertion hole 1111 is larger than an outer diameter of the optical fiber connector to ensure that an optical cable provided with an optical fiber connector can penetrate through the first cable insertion hole 1111.

[0070] As in Fig. 6, the box bottom 110 further includes a peripheral edge 112 disposed on an edge of the bottom plate 111, and the peripheral edge 112 is disposed on a side associated with the bottom plate 111 and facing the box cover 120. At least one first notch 1121 is disposed on the peripheral edge 112, and a second notch 121, corresponding to each first notch 1121, is disposed on a side wall of the box cover 120. As shown in Fig. As shown in Figure 3, when the box cover 120 covers the box bottom 110, each first notch 1121 communicates with the corresponding second notch 121 to form a first socket 160. A set of first sockets 160 is the same as a set of second installation assemblies 140. The external connector 300a of the fiber adapter 300 installed on the second installation assembly 140 faces the first socket 160, and the internal connector 300b is located in the receptacle C.

[0071] The fiber-receiving box 100 provided in this embodiment of this application can be installed on a wall and can communicate with an optical cable pipeline arranged on the wall through the first cable introduction hole 1111 to guide the optical cable home, thus implementing a hidden wiring method. Specifically, when the fiber-receiving box 100 is installed on the wall, an outer side surface (i.e., a side corresponding to the box bottom 110 and opposite to the box cover 120) of the box bottom 110 faces the wall, and the first cable introduction hole 1111 on the bottom plate 111 communicates with the optical cable pipeline arranged on the wall.When the cable tray 200 is installed on the first installation assembly 130 and the cable tray 200 is wound with the fiber patch cord of the optical cable, an optical fiber connector at one end of the fiber patch cord of the optical cable can penetrate from the first cable insertion hole 1111, enter the optical cable pipeline, and is connected to an information box located at the other end of the optical cable pipeline. The optical fiber connector at the other end of the fiber patch cord of the optical cable is configured to be connected to the internal connector 300b of the fiber adapter 300, and another optical cable can be connected to the external connector 300a of the fiber adapter 300 through the first socket 160.

[0072] Furthermore, at least two installation holes 1114 are arranged on the base plate 111. For example, a self-tapping screw or an expansion screw can penetrate through the installation hole 1114 to firmly install the fiber receiving box 100 on the wall.

[0073] As in Fig. 5 and Fig. As shown in Figure 6, the first installation assembly 130 includes one or more boundary plates 131 arranged at intervals. In particular, if the first installation assembly 130 includes one boundary plate 131, the boundary plate 131 may be semicircular to form a semi-sealed first installation position. If the first installation assembly 130 includes at least two boundary plates 131 arranged at intervals, all boundary plates 131 may enclose the first installation position.

[0074] A shape and a size of the first installation position correspond to a shape and a size of the cable tray 200. For example, when the cable tray 200 includes a cable tray cylinder body and the cable tray 200 has a cylindrical structure, a shape of the limiting plate 131 may be an arc or a circle to form a cylindrical first installation position. As shown in Fig. 7, when a diameter of the first installation position is larger than an outer diameter of the cable tray 200, the cable tray 200 may be placed in the first installation position such that an outer annular wall of the cable tray 200 is clamped to an inner side wall 131a of the restriction plate 131; or when a diameter of the first installation position is smaller than a diameter of the cable tray cylinder body, the cable tray cylinder body may be fitted onto a periphery of the restriction plate 131 such that an inner wall of the cable tray cylinder body is clamped to an outer side wall 131b of the restriction plate 131.

[0075] Optionally, a protrusion 132 is arranged on a side wall of the limiting plate 131, and the protrusion 132 is configured to fix the cable tray 200 that is plugged onto the at least one limiting plate 131. Whether the protrusion 132 is arranged on the inner side wall 131a or the outer side wall 131b of the limiting plate 131 can be determined based on an installation position of the cable tray 200 on the limiting plate 131 in order to fix the cable tray 200 to the limiting plate 131 and prevent the cable tray 200 from rotating relative to the limiting plate 131. For example, when the cable tray cylinder body 213 of the cable tray 200 is plugged onto the periphery of the limiting plate 131, as shown in Fig. 7, the projection 132 is correspondingly disposed on the outer side wall 131b of the restriction plate 131; or when the cable tray 200 is placed in the first installation position, the projection 132 is correspondingly disposed on the inner side wall 131a of the restriction plate 131.

[0076] For example, a width of the protrusion 132 may be 1 mm to 2 mm, and the width is a relative distance between a side belonging to the protrusion 132 and being away from the restriction plate 131 and a side belonging to the protrusion 132 and being close to the restriction plate.

[0077] In one example, the first cable insertion hole 1111 may alternatively be remote from the limiting plate 131 and is arranged on an outer side of the limiting plate 131. In another example, when the first cable insertion hole 1111 has a shape of a circle, a square, or the like, the limiting plate 131 may be arranged on a periphery of the first cable insertion hole 1111, and the optical cable on the cable tray 200, which is plugged onto the periphery of the limiting plate 131, may penetrate through the first cable insertion hole 1111 through a gap between two adjacent limiting plates 131. As shown in Fig. 5 to Fig. 8, when the first cable insertion hole 1111 includes a circular hole and a sector hole communicating with each other, the restriction plate 131 may be arranged on a periphery of the circular hole, and the sector hole extends to an outside of the restriction plate 131. The cable tray 200 fitted on the periphery of the restriction plate 131 does not shield the sector hole, so that the optical cable on the cable tray 200 can penetrate from the fiber accommodation box 100 through the sector hole.

[0078] Based on the above example, in order to prevent the cable tray 200 from pressing against the optical cable penetrating through the first cable insertion hole 1111 when the cable tray 200 is installed on the first installation assembly 130, as shown in Fig. 6 and Fig. As shown in Figure 7, at least two sealing columns 150 may be arranged on the bottom plate 111. A height of the sealing column 150 is less than a height of the limiting plate 131. When the cable tray 200 is installed on the first installation assembly 130, the sealing column 150 is configured to support the cable tray 200 to form a fiber space between the bottom of the cable tray 200 and the bottom plate 111, so that the optical cable on the cable tray 200 penetrates through the fiber space through the first cable insertion hole 1111 to prevent the cable tray 200 from compressing the optical cable.

[0079] Optionally, a first fixing bracket 133 is arranged on the limiting plate 131, and the first fixing bracket 133 is configured to fix the optical cable passing through the first cable insertion hole 1111. The optical cable passing through the first cable insertion hole 1111 may be the optical cable on the cable tray 200 or may be another optical cable entering the receptacle C through the first cable insertion hole 1111.

[0080] In one example, the first fixing bracket 133 may be a bracket protruding from the restriction plate 131, and the optical cable penetrating through the first cable insertion hole 1111 may be fixed to the first fixing bracket 133 by tying using a fixing piece such as a tape or a binding band, or by winding the optical cable on the first fixing bracket 133.

[0081] In another example, as in Fig. 7, a first binding hole 1311 and a second binding hole 1312 are arranged on the restriction plate 131, so that the first fixing bracket 133 is formed between the first binding hole 1311 and the second binding hole 1312, and a fixing piece such as a tape or a binding band can penetrate through the first binding hole 1311 and the second binding hole 1312 to fix the optical cable penetrating through the first cable insertion hole 1311 to the first fixing bracket 133.

[0082] Optional is, as in Fig. 6 and Fig. 7, at least one first guide element 170 is further arranged on the box bottom 110, and the first guide element 170 is arranged on the periphery of the limiting plate 131. When the cable tray 200 is plugged onto the periphery of the limiting plate 131, the optical cable on the cable tray 200 is located between the limiting plate 131 and the first guide element 170, and the first guide element 170 can be configured to limit a position of the optical cable to prevent the optical cable wound on the cable tray 200 from being ejected from the fiber accommodation box 100 due to elasticity.

[0083] In this embodiment, the first guide element 170 may be arranged at an end belonging to the circumferential edge 112 and remote from the bottom plate 111, or may be arranged on an inner side belonging to the circumferential edge 112 and facing the receptacle C, or may be arranged on a side belonging to the bottom plate 111 and facing the box cover 120.

[0084] For example, assume that a specification of the fiber accommodation box 100 provided in this embodiment of this application is 86 x 86 mm, the bottom plate 111 is a square, and circumferential edges 112 are distributed in a square. In this case, one or more first guide elements 170 distributed at intervals may be arranged at an end corresponding to a circumferential edge 112 distributed in each direction and remote from the bottom plate 111, or one or more first guide elements 170 distributed at intervals may be arranged at an end corresponding to a circumferential edge 112 distributed in each of some directions and remote from the bottom plate 111. For example, as shown in Fig. 6 and Fig. 7, at least one first guide element 170 is arranged at one end corresponding to a circumferential edge 112 distributed in each of two directions near the boundary plate 131 and remote from the base plate 111. In particular, one first guide element 170 is arranged at a circumferential edge 112 distributed in one direction, and two first guide elements 170 are arranged at a distance from one another on a circumferential edge 112 distributed in the other direction.

[0085] When the first guide element 170 is arranged at an end that belongs to the circumferential edge 112 and that is remote from the base plate 111, a sum of a height of the first guide element 170 and a height of the circumferential edge 112 is less than a height of the receptacle C and is greater than a sum of a height of the cable tray 200 and a height of the sealing column 150. When the first guide element 170 is arranged on an inner side that belongs to the circumferential edge 112 and faces the receptacle C, or is arranged on a side that belongs to the base plate 111 and faces the box cover 120, a height of the first guide element 170 is less than a height of the receptacle C and is greater than a sum of a height of the cable tray 200 and a height of the sealing column 150.The height of the receptacle C is a relative distance between the side belonging to the bottom plate 111 and facing the box cover 120 and a side belonging to the box cover 120 and facing the bottom plate 111. The height of the first guide element 170 and the height of the peripheral edge 112 are both a relative distance between an end facing the bottom plate 111 and an end facing the box cover 120.

[0086] As in Fig. 6 and Fig. As shown in Figure 7, a first projection 171 and / or a first escape hole 172 are / is arranged on a side wall belonging to one or more of the at least one first guide element 170 and which is opposite the receptacle C, and a second escape hole 122 corresponding to the first projection 171 and / or a second projection 123 corresponding to the first escape hole 172 are / is arranged on a side wall of the box cover 120. When the box cover 120 covers the box bottom 110, the first projection 171 is clamped to the second escape hole 122, and the first escape hole 172 is clamped to the second projection 123, so that the box cover 120 is firmly clamped to the box bottom 110.

[0087] In another embodiment, as in Fig. 5 to Fig. 8, at least one second cable entry hole 1122 is further arranged on the peripheral edge 112.

[0088] It can be understood that in the fiber accommodation box 100 provided in this embodiment of this application, not only a hidden wiring manner can be implemented by communicating the optical cable pipeline arranged on the wall through the first cable introduction hole 1111, but also an open wiring manner can be implemented through the second cable introduction hole 1122.For example, when the fiber accommodation box 100 is installed on the wall, if the cable tray 200 is installed on the first installation assembly 130 and the cable tray 200 is wound with the fiber patch cable of the optical cable, one end of the fiber patch cable of the optical cable can penetrate from the fiber accommodation box 100 through the second cable insertion hole 1122 and is connected in an open wiring manner to an information box arranged in another room or outside, an optical cable located between the fiber accommodation box 100 and the information box is exposed from the wall, and an optical fiber connector at the other end of the fiber patch cable of the optical cable is connected to the internal terminal 300b of the fiber adapter 300.

[0089] A number of second cable insertion holes 1122 and arrangement positions of the second cable insertion holes 1122 are not limited in this application. Optionally, as in Fig. 6 and Fig. 8, the peripheral edges 112 are distributed in a square. One or more second cable entry holes 1122 may be arranged on the peripheral edge 112, distributed in any direction, so that the optical cable on the cable tray 200 installed on the first installation assembly 130 can penetrate from the fiber receiving box 100 through the second cable entry hole 1122 in any direction for cabling.

[0090] Optionally, as shown in an enlarged view of a local structure B on the box floor 110 in Fig. 8, a detachable filler assembly 113 is disposed in every second cable entry hole 1122. In this case, the second cable entry hole 1122 can be sealed or semi-sealed using the filler assembly 113 to reduce external dust entering the receptacle C of the fiber receptacle box 100 through the second cable entry hole 1122. When the optical cable on the cable tray 200 needs to penetrate from the fiber receptacle box 100 in one direction for cabling, or another optical cable needs to enter the fiber receptacle box 100 in one direction, a filler assembly 113 disposed in the second cable entry hole 1122 in the corresponding direction can be disassembled to expose the second cable entry hole 1122.

[0091] Optionally includes, as in Fig. As shown in Figure 8, the filling assembly 113 includes a filling column 1131, and two sides of the filling column 1131, each facing the circumferential edge 112, are connected to the circumferential edge 112 using one or more connecting columns 1132. An area of ​​a connection point between the filling assembly 113 and the circumferential edge 112 is small. The filling assembly 113 can be manually inserted from the second cable insertion hole 1122, or the connecting column 1132 can be cut off using a cutting tool such as scissors to expose the second cable insertion hole 1122.

[0092] Further, a second fixing bracket 1112 corresponding to the second cable insertion hole 1122 is disposed on the box bottom 110, the second fixing bracket 1112 is configured to fix an optical cable penetrating through the second cable insertion hole 1122, and the second fixing bracket 1112 is disposed adjacent to the second cable insertion hole 1122 on the box bottom 110.

[0093] In one example, the second fixing bracket 1112 may be a bracket that protrudes from the inner side corresponding to the peripheral edge 112 and that faces the receptacle C or the bottom plate 111, and the optical cable penetrating through the second cable insertion hole 1122 may be fixed to the second fixing bracket 1112 by tying using a fixing piece such as a tape or a binding band, or by winding the optical cable on the second fixing bracket 1112.

[0094] In another example, as in Fig. 7, a third binding hole 1113 corresponding to each second cable insertion hole 1122 is provided on the bottom plate 111, and the third binding hole 1113 communicates with the corresponding second cable insertion hole 1122. The second fixing bracket 1112 is disposed at an opening corresponding to the third binding hole 1113 and facing the box cover 120, and a fixing piece such as a tape or a binding band can penetrate through the third binding hole 1113 to fix the optical cable penetrating through the second cable insertion hole 1122 to the second fixing bracket 1112.

[0095] As in Fig. 5 to Fig. As shown in Figure 7, the second installation assembly 140 includes a first side plate 141 and a second side plate 142 disposed opposite each other on the bottom plate 111. An installation slot 143 corresponding to the fiber adapter 300 is formed between the first side plate 141 and the second side plate 142 and is configured to detachably install the fiber adapter 300. One terminal of the installation slot 143 is aligned with the first notch 1121 located on the circumferential edge 112, and the other terminal is located in the receptacle C, so that an external terminal 300a of the fiber adapter 300 installed in the installation slot 143 faces the first notch 1121, and an internal terminal 300b is located in the receptacle C.

[0096] It should be noted that a plurality of second installation assemblies 140 may be arranged in the fiber accommodation box 100 provided in this application to install a plurality of fiber adapters 300, to provide more access ports for optical cables through external ports 300a of the plurality of fiber adapters 300, and further provide an optical signal to more optical communication devices such as optical network units (ONU) or optical network terminals (ONT).

[0097] Furthermore, the fiber adapter 300 is typically provided with a flange 310, and flanges 310 of different types of fiber adapters 300 are provided with different numbers of convex tabs 3101. A concave slot corresponding to the convex tab 3101 of the fiber adapter 300 can be arranged on the first side plate 141 and the second side plate 142 based on the number of convex tabs 3101 on the fiber adapter 300 and the arrangement positions of the convex tabs 3101 on the fiber adapter 300. When the convex tab 3101 of the fiber adapter 300 is clamped in the clamping slot, the fiber adapter 300 can be fixed in the installation slot 143.

[0098] For example, as in Fig. 5 to Fig. 7, the second installation assembly 140 provided in this application may correspond to the fiber adapter 300 provided with a single convex tab 3101 or symmetrically provided with two convex tabs 3101. Specifically, at least one first clamping slot 1411 is arranged on a side wall belonging to the first side plate 141 and facing the second side plate 142, and at least one second clamping slot 1421 is arranged on a side wall belonging to the second side plate 142 and facing the first side plate 141; and the at least one first clamping slot 1411 and the at least one second clamping slot 1421 are configured to clamp at least one convex tab 3101 of the fiber adapter 300. One of the at least one first clamping slot 1411 and one of the at least one second clamping slot 1421 are arranged symmetrically.

[0099] Optionally, a pressure plate 126 is arranged on the box cover 120, and the pressure plate 126 is arranged opposite the installation slot 143. When the box cover 120 covers the box bottom 110, the pressure plate 126 may abut on a side corresponding to the fiber adapter 300 installed in the installation slot 143 and facing the box cover 120 to further fix the fiber adapter 300 in the installation slot 143 and avoid mismatch between the external connector 300a of the fiber adapter 300 and the first socket 160 when the fiber receiving box 100 installed with the fiber adapter 300 is installed on the wall.

[0100] Optional, as in Fig. 5 and Fig. 7, the first side plate 141 may be disposed adjacent to a side corresponding to the circumferential edge 112 and facing the receptacle C. A height of the first side plate 141 is greater than the height of the circumferential edge 112. A fifth projection 1413 is disposed on a side wall corresponding to the first side plate 141 and opposite the receptacle C. Similarly, a hook 127 is disposed on a side wall corresponding to the box cover 120 and facing the receptacle C. When the box cover 120 covers the box bottom 110, the hook 127 is clamped to the fifth projection 1413 to firmly lock the box cover 120 and the box bottom 110. Further, the first side plate 141 may be tightly attached to the side corresponding to the circumferential edge 112 and facing the receptacle C.

[0101] Furthermore, as in Fig. 5 and Fig. 7, a third clamping slot 1412 is arranged on the side wall corresponding to the first side plate 141 and opposite to the receptacle C, the fifth projection 1413 is arranged at a side end corresponding to the third clamping slot 1412 and remote from the bottom plate 111, and when the hook 127 is clamped to the fifth projection 1413, an end corresponding to the hook 127 and close to the bottom plate 111 is located in the third clamping slot 1412.

[0102] Based on the above example, at least one guide column 180 is further arranged on the side corresponding to the circumferential edge 112 of the fiber receiving box 100 provided in this application and facing the receptacle C, and a height of the guide column 180 is greater than the height of the circumferential edge 112. A number of guide columns 180 is not limited in this application. For example, as in Fig. 5 to Fig. As shown in Figure 7, the box bottom 110 has a square structure. The box bottom 110 has four inner corners, and a guide post 180 may be arranged at each inner corner. When the box cover 120 covers the box bottom 110, the guide post 180 may guide an inner side wall of the box cover 120 to cover the box along a height direction of the guide post 180, so that the side wall of the box cover 120 can be quickly aligned with the peripheral edge 112 of the box bottom 110 when the box is covered.

When the box cover 120 covers the box bottom 110, the third protrusion 181 is clamped to the third escape hole 124 to firmly lock the box cover 120 and the box bottom 110.

[0104] Furthermore, a release structure is arranged on the fiber receiving box 100 provided in this application, and the release structure is configured to release the box cover 120 and the box bottom 110, which are firmly locked. As shown in Fig. 3 and Fig. 6, a concave slot 1123 is arranged on a side wall corresponding to the peripheral edge 112 and opposite the receptacle C. When the box cover 120 covers the box bottom 110, the side wall of the box cover 120 and the concave slot 1123 form an unlocking slot 114. A tool, such as a screwdriver, can be inserted into the unlocking slot 114, and the box cover 120 and the box bottom 110 are unlocked based on a lever principle, so that the box cover 120 is separated from the box bottom 110.

[0105] Optionally, a bottom wall corresponding to the concave slot 1123 and facing the box cover 120 is not perpendicular to a side wall corresponding to the peripheral edge 112 and facing the receptacle C. In other words, an end of the bottom wall corresponding to the concave slot 1123 and facing the box cover 120 near the receptacle C may tilt toward the bottom plate 111 relative to an end away from the receptacle C, or an end of the bottom wall corresponding to the concave slot 1123 and facing the box cover 120 away from the receptacle C may tilt toward the bottom plate 111 relative to an end near the receptacle C.

[0106] In one example, if the concave slot 1123 does not intersect the circumferential edge 112, when the unlocking tool, such as the screwdriver, is inserted into the unlocking slot 114 for unlocking, an end belonging to the unlocking tool that is inserted into the unlocking slot 114 may abut the circumferential edge 112 to provide more support during unlocking and separate the box cover 120 from the box bottom 110 based on the lever principle.

Therefore, when the unlocking tool, such as the screwdriver, is inserted into the unlocking slot 114 for unlocking, an end corresponding to the unlocking tool and inserted into the unlocking slot 114 may abut against a side wall corresponding to the second guide element 190 and facing the circumferential edge 112 to provide more support during unlocking, and the box cover 120 from the box bottom 110 based on the lever principle.

[0108] It should be noted that the second guide element 190 may be arranged adjacent with a specific gap on the side corresponding to the circumferential edge 112 and facing the receptacle C, or the second guide element 190 may be arranged without a gap on the side corresponding to the circumferential edge 112 and facing the receptacle C.

[0109] Optionally, a guide slot 191 is arranged on the side wall belonging to the second guide element 190 and opposite the receptacle C (that is, the side wall belonging to the second guide element 190 and facing the circumferential edge 112), and the guide slot 191 extends along a height direction of the second guide element 190. As shown in Fig. 6, when the second guide member 190 is arranged without a gap on the side corresponding to the circumferential edge 112 and facing the receptacle C, the guide slot 191 communicates with the concave slot 1123. When the unlocking tool, such as the screwdriver, is inserted into the unlocking slot 114 for unlocking, an end belonging to the unlocking tool and inserted through the unlocking slot 114 into the guide slot 191 can abut against the side wall corresponding to the second guide member 190 and facing the circumferential edge 112 to provide more support during unlocking, exert force along a direction of the guide slot 191 based on the lever principle, and separate the box cover 120 from the box bottom 110.
