[0001] The present application claims priority to the Chinese patent application No. 202421263804.6, filed on June 4, 2024, and entitled "Optical fiber box and optical distribution network device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] Embodiments of the present application relate to the field of optical communication technology, in particular to an optical fiber box and an optical distribution network device. BACKGROUND

[0003] With the development of the optical distribution network (ODN) industry, box-type optical fiber boxes such as pre-connection joint boxes and pre-connection fiber access terminals (FAT) are widely used.

[0004] The current large-capacity pre-connection fiber access terminal includes more than 16 ports. Due to the dense arrangement of the ports, the adapter ports cannot be integrated on the panel, but multiple adapters are molded one by one and fixed on the panel by screwing, which makes the overall material and assembly cost too high.

[0005] Utility model content

[0006] Embodiments of the present application provide an optical fiber box and an optical distribution network device, which solve the problem of high cost of the optical fiber box.

[0007] To achieve the above-mentioned purpose, the embodiments of the present application adopt the following technical solutions:

[0008] In a first aspect, the present application provides an optical fiber box, comprising: a shell, a first optical fiber adapter assembly, and a first connection panel; the first connection panel is connected with the shell; the first connection panel comprises: a plurality of first optical fiber adapters, wherein the plurality of first optical fiber adapters are integrally arranged with the first connection panel, and the first optical fiber adapter assembly is connected with the first connection panel. Thus, the connection panel is divided into two parts, which only need to be molded and connected together, wherein the first connection panel and the plurality of first optical fiber adapters are integrally arranged, without the need to install optical fiber adapters one by one on the first connection panel, thereby reducing material and labor costs. The first optical fiber adapter assembly can adjust its installation position and the number of optical fiber adapters according to demand, thereby reducing assembly difficulty.

[0009] In an optional implementation, the first fiber adapter assembly comprises a second fiber adapter. Thus, the first fiber adapter assembly has a simple structure, and the injection molding difficulty and the assembly difficulty are reduced.

[0010] In an optional implementation, the first fiber adapter assembly comprises a second connecting panel and a plurality of second fiber adapters, and the second connecting panel and the plurality of second fiber adapters are integrally arranged. Thus, the second connecting panel and the plurality of second fiber adapters are integrally arranged, and it is not necessary to install the fiber adapters one by one on the second connecting panel, thereby reducing the material cost and the labor cost. In addition, the first fiber adapter assembly can adjust the installation position and the number of fiber adapters according to requirements, thereby reducing the assembly difficulty.

[0011] In an optional implementation, the plurality of first fiber adapters are arranged along a first direction, and the first fiber adapters and the second fiber adapters are arranged along a second direction. Thus, the first fiber adapters and the second fiber adapters are arranged in different rows. The first part of the first connecting panel and the first fiber adapter assembly are independently formed, that is, the first fiber adapters and the second fiber adapters are separately formed. In this way, the fiber adapters in different rows that are close to each other are separately formed, thereby reducing the injection molding demolding difficulty.

[0012] In an optional implementation, the first fiber adapters and the second fiber adapters are staggered arranged along the first direction. The staggered arrangement means that the first fiber adapters and the second fiber adapters are alternately arranged along the first direction, thereby increasing the spacing between the first fiber adapters and the second fiber adapters, and reducing the assembly difficulty.

[0013] In an optional implementation, the plurality of first fiber adapters are arranged in an arc shape. Thus, in the case of a fixed size of the connecting panel, the plurality of first fiber adapters are arranged in an arc shape, thereby saving space. Compared with the case where the plurality of first fiber adapters are arranged in a straight line, more first fiber adapters can be arranged, and the space of the connecting panel is fully utilized.

[0014] In an optional implementation, the fiber box further comprises a second fiber adapter assembly, and the second fiber adapter assembly is connected to the first connecting panel. Thus, the connecting panel is divided into three parts, and only the three parts need to be separately formed and then connected together, thereby reducing the material cost and the labor cost. In addition, the second fiber adapter assembly can adjust the installation position and the number of fiber adapters according to requirements, thereby reducing the assembly difficulty.

[0015] In an optional implementation, the second fiber adapter assembly comprises a third fiber adapter. Thus, the second fiber adapter assembly has a simple structure, and the injection molding difficulty and the assembly difficulty are reduced.

[0016] In an optional implementation, the second fiber adapter assembly comprises a plurality of third fiber adapters and a third connection panel, and the third connection panel and the plurality of third fiber adapters are integrally arranged. In this way, the third connection panel and the plurality of third fiber adapters are integrally arranged, and it is not necessary to install the fiber adapter units on the third connection panel one by one, thereby reducing material costs and labor costs, and the second fiber adapter assembly can adjust its installation position and the number of fiber adapters according to requirements, thereby reducing assembly difficulty.

[0017] In an optional implementation, the plurality of first fiber adapters are arranged along a first direction, and the first fiber adapters and the third fiber adapters are arranged along a third direction. In this way, the first fiber adapters and the third fiber adapters are arranged in different rows. The first part of the first connection panel and the second fiber adapter assembly are independently formed in the application, that is, the first fiber adapters and the third fiber adapters are separately formed, and the fiber adapters in different rows are separately formed, thereby reducing injection molding demolding difficulty.

[0018] In an optional implementation, the first fiber adapters and the third fiber adapters are staggered arranged along the first direction. The staggered arrangement refers to that the first fiber adapters and the third fiber adapters are alternately arranged along the first direction, which can increase the spacing between the first fiber adapters and the third fiber adapters, thereby reducing assembly difficulty.

[0019] In an optional implementation, the first connection panel is provided with a first through hole, and the first fiber adapter assembly is arranged in the first through hole. In this way, the connection stability of the first fiber adapter assembly and the first connection panel is improved.

[0020] In an optional implementation, the connection manner of the first fiber adapter assembly and the first connection panel comprises mechanical fixing, welding and gluing. In this way, the first fiber adapter assembly and the first connection panel can be better connected.

[0021] In an optional implementation, the first fiber adapter assembly is integrally formed by injection molding. In this way, material costs and labor costs are reduced.

[0029] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings.

[0030] Hereinafter, the terms "first", "second", etc. are only used for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0031] In addition, in the present application, the orientation terms such as "upper", "lower", etc. are defined with respect to the orientation of the components shown in the drawings,

[0032] It should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0033] The present application provides an optical distribution network system, which is used to provide an optical transmission channel between an optical line terminal (OLT) of a local device and an optical network unit (ONU) of a remote device in an optical access network (OAN). The optical access network refers to an information transmission function of an access network using optical fiber as the main transmission medium.

[0034] From the functional point of view, the optical distribution network system can be divided into four parts from the local end to the user end, i.e. a feeder cable subsystem, a distribution cable subsystem, a drop cable subsystem and an optical fiber terminal subsystem.

[0035] The optical distribution network system includes an optical distribution network device, which for example includes optical fibers and an optical fiber box, the optical fiber box including an adapter, and the optical fibers being connected with the optical fiber adapters.

[0036] Fig. 1 is a structural schematic diagram of an optical fiber box, and Fig. 2 is a top view of the optical fiber box in Fig. 1. As shown in Fig. 1 and Fig. 2, the optical fiber box 10 comprises a shell 100, a connection panel 101, and a plurality of optical fiber adapters 102. The shell 100 is connected with the connection panel 101, and the plurality of optical fiber adapters 102 are connected with the connection panel 101.

[0037] The shell 100 and the connection panel 101 can surround a first area, and the optical fiber adapters 102 are used to connect with optical fibers in the first area, so that the optical fiber adapters 102 and the optical fibers can be better protected, and the connection stability of the optical fiber adapters 102 and the optical fibers is improved.

[0038] Embodiments of the present application do not limit the connection mode of the optical fiber adapters 102 and the connection panel 101. In some embodiments, each optical fiber adapter 102 is threadedly connected with the connection panel 101.

[0039] In order to further improve the connection stability, a sealing ring is arranged between each optical fiber adapter 102 and the connection panel 101, so that a torque can be applied to the optical fiber adapter 102 to lock the optical fiber adapter 102 on the connection panel 101. However, the assembly cost of a single optical fiber adapter is high.

[0040] Embodiments of the present application do not limit the forming mode of the optical fiber adapters 102. The optical fiber adapters 102 can be formed by high-molecular material injection molding. However, the optical fiber adapters 102 are injection molded individually, and the assembly process requires high requirements, takes a long time, and has high cost.

[0041] Therefore, embodiments of the present application provide an improved optical fiber box. The connection panel is split into two or more parts for injection molding, and then spliced, so that an integrated structure of the optical fiber adapters and the panel is realized, and the material cost and the labor cost are reduced.

[0042] Fig. 3 is a structural schematic diagram of an optical fiber box provided by an embodiment of the present application. As shown in Fig. 3, the optical fiber box comprises a shell 100, a first connection panel 11, a first optical fiber adapter assembly 12, and a plurality of first optical fiber adapters 110.

[0043] The first connection panel 11 is connected with the shell 100, the plurality of first optical fiber adapters 110 are integrally arranged with the first connection panel 11, and the first optical fiber adapter assembly 12 is connected with the first connection panel 11.

[0044] Embodiments of the present application do not limit the connection mode of the connection panel and the shell 100. In some embodiments, the connection mode of the connection panel and the shell 100 comprises mechanical fixing or welding. The mechanical fixing can comprise screw fixing connection, buckle clamping, etc.

[0045] The plurality of first fiber adapters 110 are integrally arranged with the first connection panel 11, that is, the plurality of first fiber adapters 110 and the first connection panel 11 are integrally injection molded, without the need to install the fiber adapter monomers one by one on the connection panel, thereby reducing material costs and labor costs.

[0046] The first fiber adapter assembly 12 is not limited in structure in the embodiments. In some embodiments, the first fiber adapter assembly 12 includes at least one second fiber adapter 121, and the first fiber adapter 110 and the second fiber adapter 121 are of the same structure.

[0047] The first fiber adapter assembly 12 includes at least one second fiber adapter 121, that is, the second fiber adapter 121 can include one or more second fiber adapters 121.

[0048] In some embodiments, as shown in FIG. 5, the second fiber adapter 121 is one, that is, the first fiber adapter assembly 12 includes only one second fiber adapter 121, and the second fiber adapter 121 can be injection molded independently.

[0049] In other embodiments, as shown in FIGS. 3 and 4, the first fiber adapter assembly 12 includes a second connection panel 122 and a plurality of second fiber adapters 121, and the second connection panel 122 and the plurality of second fiber adapters 121 can be integrally injection molded.

[0050] The connection panel is divided into two parts in the embodiments, and only the two parts need to be connected together after being molded respectively, wherein the first connection panel and the plurality of first fiber adapters are integrally arranged, without the need to install the fiber adapter monomers one by one on the first connection panel, thereby reducing material costs and labor costs. The first fiber adapter assembly can adjust the installation position and the number of fiber adapters according to requirements, thereby reducing assembly difficulty.

[0051] The arrangement of the plurality of first fiber adapters 110 is not limited in the embodiments. In some embodiments, the plurality of first fiber adapters 110 are arranged in an arc shape. Thus, under the condition that the size of the connection panel is fixed, the plurality of first fiber adapters 110 are arranged in an arc shape, thereby saving more space, and compared with the linear arrangement of the plurality of first fiber adapters 110, more first fiber adapters 110 can be arranged, and the space of the connection panel can be fully utilized. The arrangement of the second fiber adapter 121 can refer to the arrangement of the first fiber adapter 110 to fully utilize the space of the second connection panel 122, which will not be described herein.

[0052] In some related technologies, the first connection panel 11, the plurality of first fiber adapters 110 and the first fiber adapter assembly 12 are integrally injection molded. When the fiber adapters of adjacent rows are too close, the demolding difficulty is high, and the injection molding process is high.

[0053] Therefore, in some embodiments of the present application, the fiber adapters of different rows can be molded separately. For example, the first fiber adapters 110 and the second fiber adapters 121 can be arranged in different rows, and the first fiber adapters 110 and the second fiber adapters 121 can be molded separately.

[0054] In some embodiments, the plurality of first fiber adapters 110 are arranged along a first direction, the first fiber adapters 110 and the second fiber adapters 121 are arranged along a second direction, and the plurality of second fiber adapters 121 are arranged along a third direction, wherein the first direction is different from the second direction. That is, the first fiber adapters 110 and the second fiber adapters 121 are arranged in different rows. In some embodiments, the first direction and the third direction are substantially parallel, that is, the rows where the first fiber adapters 110 and the second fiber adapters 121 are arranged are parallel.

[0055] In the present application, the first part of the connection panel and the first fiber adapter assembly 12 are molded separately, the first fiber adapters 110 and the second fiber adapters 121 are molded separately, that is, the fiber adapters of different rows are molded separately, and the injection molding difficulty is reduced.

[0056] The present application does not limit the positional relationship between the first fiber adapters 110 and the second fiber adapters 121. In some embodiments, the projections of the first fiber adapters 110 and the second fiber adapters 121 in the x direction can be arranged in a staggered manner. Wherein, the staggered arrangement refers to the projections of the first fiber adapters 110 and the second fiber adapters 121 in the x direction are arranged alternately, which can increase the distance between the first fiber adapters and the second fiber adapters, reduce the mutual interference between the first fiber adapters and the second fiber adapters, and reduce the assembly difficulty.

[0057] The present application does not limit the connection structure of the first connection panel 11 and the first fiber adapter assembly 12. In some embodiments, the first fiber adapter assembly 12 is embedded in the first connection panel 11. For example, the first connection panel 11 is provided with a first through hole, the shape of the first fiber adapter assembly 12 is adapted to the shape of the first through hole, the first fiber adapter assembly 12 can be arranged in the first through hole and connected with the first through hole.

[0058] In some embodiments, the first connection panel 11 and the first fiber adapter assembly 12 are two parts of the connection panel. For example, the first connection panel 11 and the first fiber adapter assembly 12 are arranged in the y direction, and the first connection panel 11 and the first fiber adapter assembly 12 are connected to the housing 100 respectively.

[0059] The embodiments of the present application do not limit the connection mode of the first connection panel 11 and the first fiber adapter assembly 12. The connection mode of the first connection panel 11 and the first fiber adapter assembly 12 includes mechanical fixing, welding, and gluing.

[0060] In the above embodiments, the connection panel is divided into two parts for separate molding. In some embodiments, the connection panel can also be divided into three parts for separate molding. The fiber box further includes a second fiber adapter assembly 13 connected to the first connection panel 11. Dividing the connection panel into three parts can reduce the size of a single adapter assembly and improve the structural stability of the fiber box.

[0061] In some embodiments, the second fiber adapter assembly 13 includes at least one third fiber adapter 131, that is, the third fiber adapter 131 can be one or more.

[0062] In some embodiments, the third fiber adapter 131 is one, that is, the second fiber adapter assembly 13 only includes one third fiber adapter 131, and the third fiber adapter 131 can be independently injection molded.

[0063] In other embodiments, the second fiber adapter assembly 13 includes a third connection panel 132 and a plurality of third fiber adapters 131, and the third connection panel 132 and the plurality of third fiber adapters 131 can be integrally injection molded.

[0064] In this way, the connection panel is divided into three parts, which only need to be molded separately and then connected together, thereby reducing material and labor costs. The first fiber adapter assembly 12 and the second fiber adapter assembly 13 of the connection panel can adjust their positions and the number of fiber adapters according to requirements, thereby reducing assembly difficulty.

[0065] The embodiments of the present application do not limit the connection structure of the first connection panel 11 and the second fiber adapter assembly 13. In some embodiments, the first connection panel 11 is provided with a second through hole, the shape of the second fiber adapter assembly 13 is adapted to the shape of the second through hole, the second fiber adapter assembly 13 can be arranged in the second through hole and connected to the second through hole.

[0066] The embodiments of the present application do not limit the position of the third fiber adapter 131. In some embodiments, the fiber adapters in different rows can be separated into different types. For example, the first fiber adapter 110 and the third fiber adapter 131 can be arranged in different rows and separated into different types.

[0067] For example, the plurality of first fiber adapters 110 are arranged along a first direction, and the first fiber adapters 110 and the third fiber adapter 131 are arranged along a third direction, and the first direction intersects the third direction. In some embodiments, the plurality of first fiber adapters 110 are arranged along the first direction, and the first fiber adapters 110 and the third fiber adapter 131 are arranged along the y direction. That is, the first fiber adapters 110 in the first connection panel 11 and the third fiber adapters 131 in the second fiber adapter assembly 13 are arranged in different rows. In the present application, the first connection panel 11 and the second fiber adapter assembly 13 of the connection panel are separated into different types, and the first fiber adapters 110 and the third fiber adapters 131 are separated into different types, that is, the fiber adapters in different rows are separated into different types, which reduces the difficulty of injection molding.

[0068] In some embodiments, the first fiber adapters 110 and the third fiber adapters 131 can be arranged in a staggered manner in the x direction. The staggered arrangement refers to that the projections of the first fiber adapters 110 and the third fiber adapters 131 in the x direction are arranged alternately, which can increase the spacing between the first fiber adapters and the third fiber adapters and reduce the assembly difficulty.

[0069] The structure of the fiber box of the present application will be described below in combination with FIGS. 3, 4 and 5.

The first fiber adapter assembly 12 comprises a second connection panel 122 and a plurality of second fiber adapters 121, and the plurality of second fiber adapters 121 are arranged integrally with the second connection panel 122.

[0071] The connecting panel is divided into two parts: a first connecting panel and a first fiber adapter assembly in this embodiment, and only two parts are connected together after being molded respectively, wherein the first connecting panel and the plurality of first fiber adapters are integrally arranged, and there is no need to install fiber adapter monomers on the first connecting panel one by one, thereby reducing material cost and labor cost. Moreover, the second connecting panel and the plurality of second fiber adapters are integrally arranged, and there is no need to install fiber adapter monomers on the second connecting panel one by one, thereby reducing material cost and labor cost, and the first fiber adapter assembly can adjust the installation position and the number of fiber adapters according to requirements, thereby further reducing assembly difficulty.

[0072] Next, with reference to FIG. 3, the plurality of first fiber adapters 110 are arranged in an arc shape, and the plurality of second fiber adapters 121 are also arranged in an arc shape. In the case of a fixed size of the connecting panel, the plurality of first fiber adapters 110 and the plurality of second fiber adapters 121 are arranged in an arc shape, thereby saving more space, and compared with linear arrangement of the plurality of fiber adapters, more first fiber adapters 110 can be arranged in the case of an unchanged size of the connecting panel, thereby fully utilizing the space of the connecting panel.
