[0028] The utility model provides an optical fiber access terminal box 10.

[0029] Combination Figure 1 As shown, in one embodiment of the utility model, the fiber optic access terminal box 10 includes a cover plate 12 and a box body 11, the box body 11 is provided with an installation cavity 111 with an opening at one end, the cover plate 12 is movably covered on the opening, and a connecting portion is provided on the side of the cover plate 12 facing the installation cavity 111, and the connecting portion is used to connect the optical network unit 20, and a plurality of connectors 60 are provided on the outer side of the box body 11; the plurality of connectors 60 are respectively used to connect the optical network unit 20 and the optical fiber access unit 50.

[0030] In this embodiment, a rotating shaft and a rotating shaft hole are provided on one side of the cover plate 12 and the box body 11, so that the cover plate 12 and the box body 11 are rotatably connected, thereby facilitating the cover plate 12 to open or cover the installation cavity 111. Furthermore, a door lock is also provided on the side of the cover plate 12 and the box body 11 away from the rotating shaft, so as to fix the cover plate 12 and the box body 11, thereby improving the protection of the optical fiber connection components arranged inside the optical fiber access terminal box 10. The optical network unit ONU (Optical Network Unit) is an optical network device connected to the branch optical fiber of the splitter, which plays the role of converting the optical fiber signal into a network signal available to the family. The optical network unit 20 and the cable 30 are arranged in the optical fiber access terminal box 10, thereby improving the convenience and reliability of optical fiber connection and signal transmission.

[0031] Furthermore, the connection part provided on the cover plate 12 is used to connect the optical network unit 20, which saves the space of the installation cavity 111 occupied by the optical network unit 20, so as to facilitate the wiring and fiber storage of the cable 30 in the installation cavity 111, and also facilitate the miniaturization of the structure of the optical fiber access terminal box 10. When the cover plate 12 is opened, the optical network unit 20 is driven to rotate relative to the box body 11, so that the optical network unit 20 and the box body 11 are separated, which facilitates the wiring and maintenance of the cable 30 and improves the convenience of operation. Specifically, the connection method between the connection part and the optical network unit 20 can be a snap connection, a threaded connection, a plug-in connection, etc.

[0032] Combination Figure 1-Figure 3 As shown, in one embodiment of the present invention, the connecting portion is a latching protrusion 121 , and the latching protrusion 121 is used to be latched in a latching slot provided on the surface of the optical network unit 20 , so that the optical network unit 20 can be detachably mounted on the cover plate 12 .

[0033] In this embodiment, the optical network unit 20 and the cover plate 12 are detachably connected to facilitate the installation and maintenance of the optical network unit 20. The shape and size of the protrusion 121 protruding from the surface of the cover plate 12 are adapted to the card slot so that the protrusion 121 can be inserted into the card slot. When the optical network unit 20 is installed on the cover plate 12, under the action of gravity, the optical network unit 20 is hung on the protrusion 121 of the cover plate 12 through the card slot; when it needs to be disassembled for maintenance, it is only necessary to lift the optical network unit 20 and move it in a direction away from the cover plate 12, which further improves the convenience of installation and disassembly of the optical network unit 20. In other embodiments, the optical network unit 20 and the cover plate 12 can also be threaded.

[0034] Combination Figure 1 As shown, in one embodiment of the present invention, a cable management groove 40 is provided on the surface of the cover plate 12 facing the installation cavity 111 , and the cable management groove 40 is used to accommodate the cables 30 connected to the optical network unit 20 .

[0035] In this embodiment, since one end of the optical network unit 20 is connected to the cable 30, one end of the cable 30 needs to extend out of the outside of the installation cavity 111. Therefore, when the cover plate 12 is opened and closed, the cable 30 is prone to shaking. The cable management groove 40 provided on the cover plate 12 plays a role in fixing and limiting the cable 30, thereby improving the stability of the cable 30. The cable management groove 40 can be convexly provided on the surface of the cover plate 12, or can be formed by a concave surface of the cover plate 12, as long as it can fix and limit the cable 30.

[0036] Combination Figure 1-Figure 3 As shown, in one embodiment of the present invention, a surface of the cover plate 12 facing the installation cavity 111 is provided with a first side plate 43 and a second side plate 44 which are arranged opposite to each other. The first side plate 43 , the second side plate 44 and the cover plate 12 are enclosed to form a wire management groove 40 .

[0037] In this embodiment, the first side panel 43 and the second side panel 44 are spaced apart on the surface of the cover plate 12, and one end of the cable 30 is arranged between the first side panel 43 and the second side panel 44. The first side panel 43 and the second side panel 44 limit the cable 30 so that the end of the cable 30 connected to the optical network unit 20 is extended along the extension direction of the cable management groove 40, thereby improving the aesthetics of the cable 30.

[0038] Please continue to refer to Figure 1-Figure 3 In one embodiment of the present utility model, the shape of the cable management groove 40 is L-shaped, and the cable management groove 40 is arranged near a corner of the cover plate 12;

[0039] And / or, a plurality of wire clips 41 are protrudingly provided on one side of the second side plate 44 and the first side plate 43 opposite to each other, and the plurality of wire clips 41 are sequentially spaced apart along the extending direction of the wire management groove 40 .

[0040] In this embodiment, since the shape of the cover plate 12 is rectangular, the shape of the cable management groove 40 is designed to be L-shaped, and the cable management groove 40 is set at a corner close to the cover plate 12, so that the area of ​​the cover plate 12 occupied by the first side panel 43 and the second side panel 44 is smaller, and a avoidance is formed for the optical network unit 20. At the same time, in the present application, the cable 30 interface of the optical network unit 20 is located at the bottom of the cover plate 12, and the connector 60 arranged on the outside of the box body 11 is also located at the bottom of the box body 11. Therefore, the shape of the cable management groove 40 is designed to be L-shaped, and the optical network unit 20 is close to the L-shaped cable management groove 40, so that the cable 30 passes through the cable management groove 40, is guided from the bottom of the cover plate 12 to the top of the cover plate 12, and enters the installation cavity 111 from the top position of the box body 11, and then connects to the connector 60 at the bottom of the box body 11, that is, a cable 30 wiring similar to an S shape is formed. Compared with the method of directly connecting the cable 30 from the interface of the optical network unit 20 to the connector 60 on the outside of the box body 11, the structural design of the cable management groove 40 of this embodiment reduces the bending degree of the cable 30 and extends the service life of the cable 30.

[0041] In the case where the shape of the cable management trough 40 is limited or not limited to be L-shaped, the wire clamp 41 protruding from the first side plate 43 and the second side plate 44 further plays a role in limiting the position of the cable 30, preventing the cable 30 from falling out of the cable management trough 40. At the same time, the wire clamps 41 on the first side plate 43 and the second side plate 44 are sequentially arranged at intervals along the extension direction of the cable management trough 40, so as to facilitate the wiring of the cables 30 in the cable management trough 40. It can be understood that the wire clamp 41 can be arranged at one end of the first side plate 43 and the second side plate 44 away from the cover plate 12, and the wire clamp 41 can also be arranged at both ends close to the cover plate 12 and away from the cover plate 12.

[0042] Please continue to refer to Figure 1-Figure 3 In one embodiment of the utility model, an interface is provided at one end of the optical network unit 20, and the interface is used to connect the cable 30. A side of the cable management trough 40 facing the interface of the optical network unit 20 is provided with an avoidance gap 42, and the avoidance gap 42 is used to avoid the cable 30 from the interface of the optical network unit 20 to the cable management trough 40.

[0043] In this embodiment, the width of the L-shaped cable management trough 40 on the side facing the interface of the optical network unit 20 is close to the width of the optical network unit 20. At the same time, an avoidance gap 42 is opened on the side of the cable management trough 40 facing the optical network unit 20, so that the cable 30 arranged in the cable management trough 40 can pass through the avoidance gap 42 and be connected to the interface of the optical network unit 20. The setting of the avoidance gap 42 reduces the degree of bending of the cable 30 when it is connected to the interface of the optical network unit 20, and also improves the limiting effect of the cable management trough 40 on the cable 30.

[0044] Combination Figure 1As shown, in one embodiment of the present invention, a surface of the cover plate 12 facing the installation cavity 111 is recessed to form an installation groove 122 , and the installation groove 122 is used to install the optical network unit 20 .

[0045] In this embodiment, the cover plate 12 is concave to form a mounting groove 122, and the optical network unit 20 is installed in the mounting groove 122 to reduce the area of ​​the optical network unit 20 protruding from the cover plate 12, thereby reducing the occupation of the optical network unit 20 in the mounting cavity 111 inside the box body 11 when the cover plate 11 is closed. At the same time, when the cover plate 11 is opened, the mounting groove 122 also protects the optical network unit 20 and can prevent the optical network unit 20 from being hit to a certain extent.

[0046] Combination Figure 1-Figure 2 As shown, in one embodiment of the present invention, a plurality of buckles 112 are disposed in the box body 11 . The plurality of buckles 112 are spaced apart around the installation cavity 111 , and the buckles 112 are used to limit the cable 30 .

[0047] In this embodiment, four buckles 112 may be provided, and they are respectively located at the four corners of the box body 11. When wiring the cable 30, one end of the cable 30 is connected to the interface of the optical network unit 20, and the other end passes through the cable management slot 40 and the buckle 112 at a corner of the top of the box body 11 near the cable management slot 40 and the box body 11, and then passes through other buckles 112 in sequence and is connected to the connector 60. By providing the buckle 112, the stability of the cable 30 in the box body 11 is further improved. In other embodiments, one or two buckles 112 may also be provided, and the number is not further limited here.

[0048] The utility model also provides a fiber optic access device. The fiber optic access device includes an optical network unit 20, a cable 30, a fiber optic access unit 50, and a fiber optic access terminal box 10. The specific structure of the fiber optic access terminal box 10 refers to the above embodiment. Since the fiber optic access device adopts all the technical solutions of all the above embodiments of the fiber optic access terminal box 10, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0050] In this embodiment, the optical network unit 20 is also provided with a plurality of interfaces to respectively connect the power line, the optical fiber and the network transmission line, and the cable management slot 40 is also provided with a plurality of avoidance gaps 42, and a plurality of cables 30 respectively pass through the cable management slot 40 through the avoidance gaps 42 to enter the installation cavity 111 and are connected with different connectors 60. Through the structural design of the present application, the optical network unit 20 is arranged on the cover plate 12, thereby saving the internal space of the box body, so that different cables 30 can be arranged in the optical fiber access terminal box 10 in an aesthetically pleasing and convenient manner, thereby improving the convenience of wiring and maintenance.

[0051] The fiber access unit 50 is arranged at the center of the box body 11. The fiber access unit 50 includes a fixed structure and an adapter 60 for connecting the optical fibers, which improves the convenience of fiber access. At the same time, the optical fiber can be accessed inside the box body 11. Since the optical network unit 20 is arranged on the cover plate 12 in the present application, there is more space inside the box body 11 to arrange the fiber access unit 50 and the connection of the optical fibers, which also improves the convenience of fiber access. Furthermore, since the optical network unit 20 is arranged on the cover plate 12, there is a larger space on the periphery of the fiber access unit 50 for storing the optical fibers.
