[0038] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0039] In order to solve the technical problem of single function of multifunctional optical cable switching box in the prior art, the embodiment of the utility model provides a multifunctional optical cable switching box, which combines the functions of optical fiber splicing and switching, and has independent partitions to prevent interference between the optical fiber splicing area and the optical fiber switching area.

[0040] The utility model embodiment provides a multifunctional optical cable adapter box, referring to Figure 1 The multifunctional optical cable switching box includes a box body 1, which includes a blocking structure 11, an optical fiber splicing area 12 and an optical fiber switching area 13. The optical fiber splicing area 12 includes: at least one group of optical cable inlets and outlets 121, a first storage compartment 122 and an optical fiber splicing assembly installed in the first storage compartment 122. The optical fiber switching area 13 includes: a second storage compartment 131 and an optical fiber switching assembly installed in the second storage compartment 131. Along the length direction of the box body 1, the optical fiber splicing area 12 and the optical fiber switching area 13 are located on both sides of the blocking structure 11, and the blocking structure 11 has at least one optical fiber channel for connecting the first storage compartment 122 and the second storage compartment 131. The optical fiber splicing assembly is used to connect the first optical fiber group of the optical cable entering the optical fiber splicing area 12 through the optical cable inlet and outlet 121 to form a complete optical cable line. The optical fiber switching assembly is used to switch the second optical fiber group of the optical cable entering the optical fiber switching area 13 from the optical fiber splicing area 12 through the optical fiber channel to form a quick-connect interface.

[0041] Specifically in this embodiment, the optical cable enters the optical fiber connection area 12 of the box body 1 through the optical cable entrance and exit 121. Here, the outer skin of the optical cable needs to be removed to expose the optical fiber inside. The optical cable can be divided into an input optical cable and an output optical cable. The first optical fiber group in the input optical cable is coiled in the first storage compartment 122 and connected with the optical fiber connection assembly and the optical fiber in the output optical cable; the second optical fiber group in the input optical cable passes through the optical fiber channel to enter the second storage compartment 131 and is transferred to the optical fiber switching assembly, which is convenient for the external optical fiber equipment to quickly connect with the optical fiber switching assembly. It should be noted that some optical fibers in the output optical cable can also pass through the optical fiber channel to enter the second storage compartment 131 and be transferred to the optical fiber switching assembly; after the threading is completed, the optical fiber channel is sealed, and the barrier structure 11 separates the optical fiber connection area 12 and the optical fiber switching area 13, each forming an independent space to prevent mutual interference between the optical fiber connection area 12 and the optical fiber switching area 13, meet various forms of configuration and transfer, and ensure that the internal optical fiber signal is not affected by the external environment.

[0042] It is understandable that the second optical fiber can also be connected to the pigtail in the first accommodating chamber 122, and the pigtail is transferred to the optical fiber switching assembly after passing through the optical fiber channel. The multifunctional optical cable switching box in the above embodiment can realize the three functions of optical fiber fusion, optical fiber switching and optical fiber terminal in one, and is physically divided into independent connection area and switching area, which effectively avoids mutual interference during operation. This design not only meets the needs of various configurations and switching, but also ensures the safety, stability and reliability of the optical fiber in the box in harsh external environments. The switching box is made of high-quality materials, has excellent corrosion resistance, external impact resistance and waterproof performance, is suitable for complex outdoor environments, can be quickly opened and plugged in under outdoor conditions, and is quick and efficient to operate and maintain, so as to meet the special needs of quickly establishing a field optical transmission system. In addition, its wall-mounted installation method and large-size horizontal polypropylene (PP) material buckle design make installation and sealing operations convenient and reliable.

[0043] It should be noted that the shape of the box body 1 can be selected as a rectangular structure, the length can be 500-600mm, the width can be 200-250mm, and the height can be 100-120mm. The material of the box body 1 can be selected from polypropylene (PP) and glass fiber (GF), and the reference standard is the YDT / T814.1 standard. The optical cable entrance and exit 121 can be set to 1-4 groups as needed, and the applicable optical cable diameter is 10-14mm, which is convenient for the connection and switching of multiple groups of optical cables, and increases the capacity of the box body 1. The number of optical fiber channels can be set to 1-4 as needed, which is convenient for multiple groups of optical fibers to pass through the barrier structure 11 to connect different types of optical fiber switching components.

[0044] In some embodiments, the barrier structure 11 is integrally formed with the box body 1, and the barrier structure 11 is extended along the width direction of the box body 1. The box body structure can be manufactured by a customized mold, which is convenient for integral molding and improves the strength of the box body structure. Figures 3 - 5 , reinforcing ribs can be provided on the outer surface of the box body 1 to further enhance the strength of the box body and make it more suitable for outdoor environments.

[0045] In some embodiments, a seal 111 is provided in the optical fiber channel for sealing the optical fiber channel before or after the optical fiber is inserted. The seal 111 can be fixedly connected to the optical fiber channel, and a sealing joint can be used for the seal 111. The sealing joint has good dustproof and waterproof performance. Before or after the optical fiber enters the sealing joint, the gap at the optical fiber channel can be well sealed and protected with a sealant, and the protection level can reach IP65, so that the first accommodating chamber 122 and the second accommodating chamber 131 form an independent space.

[0046] In some embodiments, the optical fiber splicing assembly includes at least one splicing tray 123 fixedly arranged in the box body 1, and the splicing trays 123 are stacked along the thickness direction of the box body 1. Specifically, the number of splicing trays 123 can be selected as 2 - 4, and the number of fusion splicing cores of each splicing tray 123 is 24 - 48 cores. The optical fibers of different optical cables can be fusion spliced or cold spliced on different splicing trays 123. The fusion splicing connection method is to fuse the end faces of two optical fibers together by high-temperature melting to form a permanent connection, with low loss, stable signal transmission, and firm connection. It is usually used in long-term stable optical fiber networks with low loss and high signal transmission quality. The cold splicing connection method is to connect the optical fibers using special connectors and adhesives without heating, and the connection is relatively simple. It is suitable for temporary or convenient occasions and is relatively easy to operate. The multifunctional optical cable adapter box of this embodiment is suitable for various optical fiber splicing methods.

[0047] In the above embodiment, an optical cable fixing member is arranged in the first accommodation chamber 122, and the position of the optical cable fixing member is close to the optical cable entrance / exit 121. Refer to Figure 1 , the optical cable fixing member includes a conductive sheet 124 and a hose clamp 125. The conductive sheet 124 is fixedly connected to the box body 1. The conductive sheet 124 is used to support the optical cable, and the hose clamp 125 is used to fix the optical cable on the conductive sheet 124 to prevent the optical cable from shifting. The conductive sheet 124 is connected to the box body 1 through a ground wire to prevent electric shock and leakage.

[0048] In some embodiments, the optical fiber adapter assembly includes at least one set of slide rails 132 and at least one aviation adapter 133. One set of slide rails 132 is fixedly arranged in the second accommodation chamber 131. The set of slide rails 132 is arranged at intervals, and the mutually facing sides thereof have sliding grooves, such that the aviation adapter 133 can be slidably disassembled and assembled in the sliding grooves. The input end of the aviation adapter 133 can be spliced with multiple optical fibers in the second optical fiber group, and its output end is a quick-connect socket for male head docking or female head docking. Refer to Figure 2 , two sets of slide rails 132 can be arranged, which are respectively located on both sides of the second accommodation chamber 131. The number of aviation adapters 133 is the same as the number of sets of slide rails 132. The second optical fiber group entering the second accommodation chamber 131 from the optical fiber channel can be connected to the input end of the aviation adapter 133. When it is necessary to connect the second optical fiber group to an external optical fiber device, only need to mutually plug the aviation adapter 133 and the adapter suitable for it. After use, reinstall the aviation adapter 133 on the slide rails 132, which is very convenient.

[0049] In some embodiments, the optical fiber adapter assembly includes a mounting plate 135 and at least one FC adapter 134. The mounting plate 135 is fixedly installed in the second accommodation chamber 131, and the FC adapters 134 are arranged and fixed on the mounting plate 135. The mounting part of the mounting plate 135 and the FC adapter 134 is a bevel structure, so that the main body of the FC adapter 134 is arranged at an angle with the bottom surface of the box body 1. The number of FC adapters 134 is not less than the number of optical fibers in the second optical fiber group. Both ends of the FC adapter 134 have quick-insert interfaces. Its input end is used to be connected to the optical fibers in the second optical fiber group one by one, and its output end forms a one-to-one quick-connection interface.

[0050] In the above embodiments, the mounting plate 135 is fixed in the second accommodation chamber 131 by screws, the FC adapter 134 is fixed on the mounting plate 135, the FC adapters 134 can be arranged in a linear array, the end of the optical fiber in the second optical fiber group is connected to the input end at the bottom of the FC adapter 134, and the bevel structure provides space for the combination part of the optical fiber and the FC adapter 134. At the same time, it makes the side of the FC adapter 134 facing the box body 1 convenient for an external optical fiber device to be connected to the FC adapter 134. The output end of the FC adapter 134 has a detachable cap structure to protect the optical fiber.

[0051] In some embodiments, the box body 1 includes a lower box body 101, a first upper box body 102 and a second upper box body 103.
