Description

Technical Field

[0001] The utility model relates to the technical field of optical communications, in particular to a multifunctional fiber splitting box. Background Art

[0002] The existing fiber splitter box is used for introducing or connecting the main optical fiber and performing fiber splitting inside the box. The multiple sub-optical fibers after fiber splitting are connected to each customer optical fiber to realize information transmission from the main optical fiber to each customer optical fiber.

[0003] Sub-fibers and customer fibers can usually be connected by fusion splicing or pre-termination. The fusion splicing method is to connect one end of the sub-fiber to one end of the customer fiber through a fusion splicing process. This method is relatively cheaper, but the customization flexibility is relatively low. It cannot be flexibly configured to connect with different numbers of clients. It is relatively complicated to make changes and requires re-fiber splitting and fusion splicing. The pre-termination method is to pre-customize each port inside the box, pre-customize the corresponding fiber splitting and fiber routing inside the box, and realize the connection between the main port and each sub-port inside the box. The main port and each sub-port are equipped with corresponding docking parts. The main fiber and each customer fiber can be directly and quickly docked with the docking parts, plug and play. During the actual connection, the main fiber is docked with the main port, and the client to be docked is docked with each sub-port to complete the signal transmission for each client. This method is relatively more convenient to operate and can flexibly adapt to various numbers of clients.

[0050] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Example 1:

[0052] This embodiment provides a multifunctional fiber distribution box, such as Figure 1-Figure 5 As shown, it includes: a box body 1, a welding panel 2 and a pre-terminated panel 3, wherein:

[0053] like Figure 1 As shown, the side end face of the box body 1 is a butt end face 13 , and the butt end face 13 has at least one first main fiber hole 11 and a plurality of first secondary fiber holes 12 .

[0054] In this embodiment, the box 1 is used to introduce or connect a main optical fiber, and performs fiber splitting within the box 1. The multiple sub-optical fibers after fiber splitting are connected to various client optical fibers to achieve information transmission from the main optical fiber to the various client optical fibers. The multiple first secondary fiber holes 12 are arranged in an array on the connecting end surface 13.

[0055] In this embodiment, the main optical fiber is used to transmit the total signal, the customer optical fiber leads to different clients, and the sub-optical fiber is obtained by splitting the main optical fiber and is used to transmit the corresponding signal to each customer optical fiber respectively, and finally to each client, completing the information transmission of each client.

[0056] In order to adapt to both fusion butt joint and pre-terminated butt joint, this embodiment provides both a fusion panel 2 and a pre-terminated panel 3, and the corresponding structural design is as follows:

[0057] like Figure 1-Figure 3As shown, at least one second main fiber hole 21 and multiple second secondary fiber holes 22 are provided on the welding panel 2; when welding is adopted, the welding panel 2 is fitted on the butt joint end face 13, and the first main fiber hole 11 and the corresponding second main fiber hole 21 are positioned correspondingly and interconnected, and the first secondary fiber hole 12 and the corresponding second secondary fiber hole 22 are positioned correspondingly and interconnected; the second main fiber hole 21 is used for introducing the main optical fiber, and the main optical fiber is divided into multiple sub-optical fibers inside the box 1, and the second secondary fiber hole 22 is used for introducing the customer optical fiber and welding it with the corresponding sub-optical fibers inside the box 1.

[0058] like Figure 1 、 Figure 4 and Figure 5 As shown, the pre-termination panel 3 is provided with a plurality of third secondary fiber holes 31, and each of the third secondary fiber holes 31 is provided with a pre-termination component 33; when pre-termination docking is adopted, the pre-termination panel 3 is fitted on the docking end face 13, and each of the third secondary fiber holes 31 is correspondingly communicated with the corresponding first secondary fiber hole 12; one of the pre-termination components 33 is used for docking with the main optical fiber, and the other pre-termination components 33 are used for docking with the customer optical fiber.

[0059] In this embodiment, when pre-terminated docking is used, the first secondary fiber hole 12 used for docking with the main optical fiber can be pre-docked with the other first secondary fiber holes 12 inside the box 1 through the pre-fabricated optical fiber through the fiber splitting, thereby ensuring that the first secondary fiber hole 12 is connected to the other first secondary fiber holes 12. After the pre-terminated panel 3 is affixed to the docking end face 13, since the third secondary fiber holes 31 on the pre-terminated panel 3 correspond to the first secondary fiber holes 12 on the docking end face 13, the main optical fiber and each customer optical fiber can be directly docked with the pre-terminated components 33 on the corresponding third secondary fiber holes 31, and can be docked with the pre-fabricated optical fiber inside the box 1, thereby achieving the fiber splitting effect inside the box 1. In this embodiment, the pre-terminated component 33 is a customized connector. The pre-terminated component 33 is docked with the corresponding pre-fabricated optical fiber on the inside of the box 1, and the pre-terminated component 33 is used to dock with the connector on the main optical fiber or the customer optical fiber on the outside of the box 1, and the docking is convenient and plug-and-play.

[0060] In this embodiment, the number of the first secondary pores 12 is the same as the number of the second secondary pores 22, and the aperture of the first secondary pores 12 is larger than the aperture of the second secondary pores 22; the number of the first secondary pores 12 is greater than the number of the third secondary pores 31, and the aperture of the first secondary pores 12 is smaller than the aperture of the third secondary pores 31.

[0061] In this embodiment, under different optical fiber docking requirements, by replacing the fusion panel 2 or the pre-terminated panel 3, the fiber splitter box can take into account both the fusion docking method and the pre-terminated docking method, thereby improving the compatibility and flexibility of the fiber splitter box for different application scenarios.

[0062] This embodiment takes into account that when the fusion splicing method is adopted, the number of clients that need to be connected may be small, and the main optical fiber does not need to split all the sub-optical fibers for connection. Therefore, in addition to the split sub-optical fibers, the main optical fiber generally has an unsplit part, which needs to be led out of the box 1. Therefore, this embodiment also involves the following designs:

[0063] like Figure 1 As shown, at least one fiber outlet hole 14 is further provided on the butt joint end face 13 ; when fusion splicing is adopted and the main optical fiber is divided into multiple sub-optical fibers and one auxiliary optical fiber, the fiber outlet hole 14 is used for leading the auxiliary optical fiber out from the inside of the box 1 .

[0064] In this embodiment, the arrangement of the holes on the docking end surface 13 can be: the first main fiber hole 11 is located on one side of the docking end surface 13, the fiber outlet hole 14 is located on the other side of the docking end surface 13, and the plurality of first secondary fiber holes 12 are arrayed between the first main fiber hole 11 and the fiber outlet hole 14.

[0065] Furthermore, in this embodiment, in order to ensure the neatness of the routing layout of each optical fiber in the box 1, this embodiment also involves the following designs:

[0066] like Figure 6 As shown, a wiring box 4 is further provided inside the box 1 , wherein: the wiring box 4 is provided on the lower surface of the inner side of the box 1 , and the wiring box 4 includes at least one first sub-fiber opening 41 and multiple second sub-fiber openings 42 .

[0067] The first sub-fiber port 41 and the second sub-fiber ports 42 are connected to each other. When different docking modes are used, the first sub-fiber port 41 and the plurality of second sub-fiber ports 42 need to be applied in different forms.

[0068] When fusion splicing is adopted, the second sub-fiber port 42 is used for introducing the customer optical fiber, and the first sub-fiber port 41 is used for leading out the customer optical fiber and fusion splicing it with the sub-fiber branched from the main optical fiber.

[0069] Further, in the embodiment, the main optical fiber is introduced from the first main fiber hole 11, and can be routed from one side outside the routing box 4 to a position close to the first sub-fiber port 41, and the main optical fiber is spliced and divided at the position to obtain a plurality of sub-optical fibers, thereby facilitating the fusion splicing of the sub-optical fibers and the customer optical fiber. Meanwhile, if there is a vice optical fiber after the division, the vice optical fiber can be routed from the other side outside the routing box 4 and introduced outside the box 1 from the fiber outlet hole 14.

[0070] When the pre-terminated butt joint is adopted, the box 1 is further provided with a prefabricated optical fiber, wherein one end of the prefabricated optical fiber is connected to the pre-terminated assembly 33 for butt joint with the main optical fiber, and the other end of the prefabricated optical fiber is introduced into the routing box 4 from one of the second sub-fiber ports 42, and the prefabricated optical fiber is divided into a plurality of prefabricated sub-fibers in the routing box 4. Each of the prefabricated sub-fibers is introduced from a corresponding second sub-fiber port 42, and the prefabricated sub-fiber introduced from the second sub-fiber port 42 is connected to the pre-terminated assembly 33 for butt joint with the customer optical fiber. Further, a limiting hole can be provided on each side of the routing box 4, one of which is used for the main optical fiber introduced from the first main fiber hole 11 to pass through and be limited, and the other is used for the vice optical fiber to pass through, be introduced from the fiber outlet hole 14 and be limited.

[0071] Further, the fusion panel 2 and the pre-terminated panel 3 need to be fixed on the butt joint end face 13 in a corresponding form, therefore the embodiment relates to the following design:

[0072] As shown in Figure 7-Figure 9 the butt joint end face 13 is further provided with a plurality of first threaded holes 15; the fusion panel 2 is provided with a plurality of first through holes 23, when the fusion butt joint is adopted, the first through holes 23 are used to correspond to the first threaded holes 15, the first threaded holes 15 and the first through holes 23 are matched by screws to attach the fusion panel 2 on the butt joint end face 13; the pre-terminated panel 3 is provided with a plurality of second through holes 32, when the pre-terminated butt joint is adopted, the second through holes 32 are used to correspond to the first threaded holes 15, the first threaded holes 15 and the second through holes 32 are matched by screws to attach the pre-terminated panel 3 on the butt joint end face 13.

[0073] Further, considering that the actual working environment of the fiber division box is relatively complex, it is necessary to ensure the waterproofness of the fiber division box and avoid liquid entering the box 1 through the holes on the butt joint end face 13 as much as possible to avoid damage to the optical fibers and elements inside the box 1, therefore the embodiment further relates to the following design:

[0074] The inner side walls of the first main fiber hole 11, the first vice fiber hole 12, the second main fiber hole 21, the second vice fiber hole 22 and the third vice fiber hole 31 are funnel-shaped.

[0075] In this embodiment, since the inner sidewalls of each hole are funnel-shaped (horizontally funnel), when liquid flows through the hole, it is difficult to flow into the interior of the box body 1 along the hole, thereby achieving a waterproof effect.

[0076] In order to further improve the overall waterproofness of the device, this embodiment also involves the following designs:

[0077] When welding is used for butt welding, a sealing ring is provided between the welding panel 2 and the butt end face 13 ; when pre-terminated butt welding is used, a sealing ring is provided between the pre-terminated panel 3 and the butt end face 13 .

[0078] Furthermore, in this embodiment, if Figure 10 As shown, the multifunctional fiber distribution box further includes a cover plate 5 , and the cover plate 5 is axially connected to the upper end of one side of the box body 1 .

[0079] At the same time, a limit lock is also provided on the periphery of the box body 1, and the limit lock is axially connected to the periphery of the box body 1, a first limit platform is provided on the inner side of the limit lock, and a second limit platform is provided on the upper surface of the cover plate 5. When the cover plate 5 is covered on the top of the box body 1 and the limit lock is flipped upward, the upper end of the limit lock is covered on the upper surface of the cover plate 5, and the first limit platform and the second limit platform are abutted, so that the cover plate 5 is locked. The locking member used in this locking method does not require a separate tool to open or lock, which further improves the flexibility of use of the device.

[0080] like Figure 11 As shown, a plurality of fusion limit plates 16 are provided inside the box 1. The plurality of fusion limit plates 16 are arranged parallel to each other on the lower surface inside the box 1. The space between two adjacent fusion limit plates 16 is used for fusion splicing the customer optical fiber and the corresponding sub-optical fiber.

[0081] like Figure 11 As shown, a plurality of fiber coiling limit platforms 17 are provided inside the box body 1. The plurality of fiber coiling limit platforms 17 are provided on the lower surface inside the box body 1 and are provided around the circumference of all the fusion limit plates 16. The fiber coiling limit platforms 17 are used for the main optical fiber to be coiled around.

[0082] In this embodiment, the fiber coiling limiting platform 17 is arc-shaped, and the optical fiber can be coiled around the periphery of each fiber coiling limiting platform 17 .

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
