Description

Technical Field

[0001] This utility model relates to the technical field of optical cable laying tools, and in particular to an optical cable distribution box that carries multiple services. Background Technology

[0002] Depending on the fiber optic cable laying method and user requirements, operators can offer a variety of services, such as FTTH, leased lines, and passive wavelength division multiplexing (WDM). Since fiber optic cable lines are generally long, fiber distribution boxes are needed along the route to perform fiber splicing, enabling long-distance cable laying and individual user connections. In traditional fiber optic services, each service has its own corresponding fiber distribution box, which suffers from poor resource integration and cumbersome management. For example, fiber optic cables laid in commercial buildings, due to the lack of resource integration, require on-site excavation and laying when users need to install cables for service activation. This leads to frequent excavation and serious duplication of construction, hindering the rapid activation of various services and making it impossible to meet users' service activation requirements in the shortest possible time. Therefore, the ability to quickly activate services according to user needs has become a test of operators' capabilities, directly impacting their competitiveness in the industry. Although there are a few fusion splicing methods that allocate various services to a single optical fiber distribution box, the wiring is generally messy and services are not arranged in a zoned manner, making it difficult to troubleshoot later and easily affecting the status of other optical fiber fusion splices, thus causing unnecessary secondary faults.

[0003] Therefore, improvements to the fiber optic distribution box are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a fiber optic distribution box that can meet the converged access of optical fibers in different types of services, with orderly service partitioning and neat wiring inside the box, which helps to improve the access integration capability of optical fibers and increase the service activation speed.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a fiber optic distribution box carrying multiple services, including a box body, a door that can be opened and closed is hinged on the box body, cable passage holes are provided at the bottom of the box body, and the box body is divided into a dedicated service area and a general service area.

[0006] The dedicated line service area is fixedly installed with an integrated melting and dispensing tray. The integrated melting and dispensing tray is rotatably equipped with a stacked flip-type structure. Fiber coil opening rings are fixedly installed on the periphery of the integrated melting and dispensing tray and on the flip-type structure, respectively.

[0007] At least two sets of optical splitter slots are arranged and installed in the general service area.

[0008] Fiber coiling devices are respectively provided on the side of the integrated fusion and distribution tray in the dedicated line service area and on the side of the optical splitter slot in the ordinary service area.

[0009] As a preferred technical solution, the dedicated line service area and the ordinary service area are arranged vertically within the enclosure; the two sets of optical splitter slots are arranged vertically within the enclosure; and the two sets of fiber coiling devices are arranged diagonally within the enclosure.

[0010] As a preferred technical solution, the fiber coiling device includes at least three open fiber coil rings arranged and installed.

[0011] As a preferred technical solution, a fiber distribution box mounting device is arranged and installed on the rear wall of the box.

[0012] As an improvement to the above technical solution, the fiber distribution box mounting device includes a box mounting folding plate and a mounting support folding plate that are matched for limiting. The upper part of the box mounting folding plate is attached to and fixedly connected to the surface of the box. A mounting gap is formed between the lower part of the box mounting folding plate and the box. The upper part of the mounting support folding plate extends into the mounting gap. A fixing hole is provided through the lower part of the mounting support folding plate. A gap is also formed between the lower part of the mounting support folding plate and the box.

[0013] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0014] 1. It can concentrate different fiber optic service types, such as leased line services, FTTH services, and passive wavelength division multiplexing services, into one fiber distribution box, which helps to quickly activate related services.

[0015] 2. Other services besides dedicated line services can be accessed from the optical splitter in the optical splitter slot, so that the remaining fiber core resources can be transferred to the next level of equipment for use with the help of the fiber removal process, thereby greatly improving the utilization rate of optical fiber core resources.

[0016] 3. Multiple services are physically partitioned within the enclosure, facilitating service differentiation and rapid activation. The neat and orderly cabling within the enclosure makes subsequent maintenance convenient, thereby greatly improving work efficiency and helping to reduce operation and maintenance costs.

[0017] 4. Because multiple services are integrated into one fiber distribution box, optical cable resources can be effectively managed and utilized. Quickly launching services also helps to enhance the operator's competitiveness. At the same time, it reduces the need for repeated laying of optical cables and excavation of municipal roads, indirectly reducing construction costs. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figures 1 to 7 As shown, a multi-service optical fiber distribution box is used to split and splice optical fibers in an optical cable. It can aggregate various services within a single box 1, improving the utilization rate of optical fiber core resources and facilitating rapid activation of related services. Specifically, it includes a box 1 with a hinged door 2 that can be opened and closed to provide enclosed protection for the internal components, fiber splice points, and fiber coils. The bottom of the box 1 has cable entry holes 3 for the introduction of optical cables and the exit of spliced ​​optical cables and drop cables.

[0029] In this embodiment, the enclosure 1 is divided into a dedicated line service area S1 and a general service area S2. The dedicated line service area S1 is used to complete the fusion splicing of optical fibers for dedicated line services, while the general service area S2 is used to complete the fusion splicing of optical fibers for FTTH services, passive wavelength division multiplexing services, etc. This realizes the physical partitioning of services within the enclosure, which facilitates rapid positioning when laying optical cables, thereby improving the integration effect of optical fiber access and the speed of activating related services.

[0030] A miniaturized fusion splicing tray 4 is fixedly installed within the dedicated line service area S1. A stacked, flip-type structure 5 is rotatably mounted on the fusion splicing tray 4. Fiber coil opening rings 6 are fixedly installed on the periphery of the fusion splicing tray 4 and on the flip-type structure 5. The flip-type structure 5 can be a plate-like structure, with multiple layers assembled via pivots to allow for flipping, thereby increasing the capacity of the fiber distribution box and its fiber splicing capability. It also helps to avoid interference during lower-layer fiber splicing operations, contributing to ensuring the efficiency of fiber splicing operations. The fiber coil opening rings 6 are used to constrain the fiber layout during splicing, preventing misaligned wiring from being pulled by the flip-type structure 5, thus helping to ensure the robustness and stability of the fiber splicing.

[0031] At least two sets of optical splitter slots 7 are installed within the ordinary service area S2, and these slots 7 are used for plugging in and installing optical splitters. The ordinary service area S2 is used for activating FTTH services, passive wavelength division multiplexing (WDM) services, etc. In this embodiment, the leased line service area S1 and the ordinary service area S2 are arranged vertically within the enclosure 1, and the two sets of optical splitter slots 7 are also arranged vertically within the enclosure 1, making it easy to locate various services, facilitating fiber optic splicing during service activation, and subsequent maintenance.

[0032] In this embodiment, fiber coiling devices are respectively provided on the side of the fusion splicing tray 4 in the dedicated line service area S1 and on the side of the optical splitter slot 7 in the ordinary service area S2. The two sets of fiber coiling devices are arranged diagonally within the housing 1, which helps to meet the standard requirement for the coiling radius of the pigtails, i.e., a coiling radius greater than 50mm. Simultaneously, it ensures that the optical fiber cabling within the housing 1 is neat and orderly, facilitating subsequent troubleshooting or maintenance. Specifically, the fiber coiling device includes at least three open coiling rings 6, which are arranged in a triangular or rectangular pattern depending on the number installed, to facilitate the coiling of the pigtails.

[0033] like Figure 3 and Figure 4As shown, a fiber distribution box mounting device is installed on the rear wall of the housing 1 to achieve the installation and fixation of the fiber distribution box. The fiber distribution box mounting device includes a housing mounting folding plate 8 and a mounting support folding plate 9 with limiting cooperation. The housing mounting folding plate 8 is used to fixally connect to the housing 1, and the mounting support folding plate 9 is used to fixally connect to a support body. Then, the two are locked together by limiting engagement, so that the fiber distribution box can be easily removed from the support body. To ensure the stability of the fiber distribution box mounting, the length of the housing mounting folding plate 8 and the mounting support folding plate 9 can correspond to the width of the housing 1, and two sets are arranged vertically opposite each other on the rear wall of the housing 1 to balance the mounting effect and installation cost.

[0034] Specifically, the upper part of the box-mounting folding plate 8 is fitted and fixedly connected to the surface of the box body 1, and a mounting gap 10 is formed between the lower part of the box-mounting folding plate 8 and the box body 1. The upper part of the mounting support folding plate 9 extends into the mounting gap 10, and a gap is also formed between the lower part of the mounting support folding plate 9 and the box body 1. When used outdoors, this prevents rainwater flowing along the support from seeping into the box. A fixing hole 11 is provided through the lower part of the mounting support folding plate 9, which is used to connect it to the support through cooperation with expansion bolts, etc.

[0035] like Figure 5 , Figure 6 and Figure 7 As shown, when activating various services, the optical fiber is laid out in an orderly manner within the enclosure 1, facilitating fiber coiling and splicing operations during service activation, and also simplifying subsequent troubleshooting and routine maintenance. Figure 5 For example, the external dimensions of the box 1 are 400×580×140mm, and it is designed for indoor wall mounting. First, the box mounting plate 8 is welded to the back of the box 1. Then, the mounting support plate 9 is installed and fixed to the cavity wall. Finally, the box mounting plate 8 is hung onto the corresponding mounting support plate 9. The installation operation is simple and convenient. Figure 5 The diagram shows two of the aforementioned flip-type structures 5 and two sets of the aforementioned optical splitter slots 7, with each set of optical splitter slots 7 having three 1-to-8 optical splitters plugged in, which can respectively meet the carrying and rapid activation of each set of 24-core services.

[0036] Therefore, by using a single 48-core optical cable entering the enclosure 1, the rapid activation of 24-core leased line services, 24-core FTTH services, and 24-core passive wavelength division multiplexing (WDM) services can be simultaneously achieved. Furthermore, since the FTTH and passive WDM services are accessed from the optical splitter, there are still 18 optical cable cores available for transfer to the next level of equipment using the fiber stripping function, thus significantly improving the utilization rate of optical fiber core resources. Excess fiber length can be coiled around the fusion splicing tray 4 in the upper left corner. The terminated pigtails of the leased line service area S1, after being managed by the outer ring of the flip structure 5, run from the outside of the flip axis of the flip structure 5 to the upper right corner of the enclosure 1 for excess length storage, and finally exit the enclosure 1 through the cable passage 3 at the lower right side.

[0037] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
