Description

Technical Field

[0001] This application relates to the field of fiber optic socket box technology, and particularly to a fiber optic socket box. Background Technology

[0002] In fiber-to-the-home (FTTH) cabling scenarios, pre-defined patch cords are commonly used for connections. To account for construction errors, a certain amount of redundant cable is usually coiled and stored in the socket box. Meanwhile, the fiber optic connectors attached to these patch cords are prone to end-face contamination or mechanical damage during long-term insertion and removal, requiring on-site repair. Existing repair solutions suffer from insufficient reliability in on-site connector assembly, while replacing the entire patch cord involves a large amount of work and is costly. Furthermore, the internal space of the fiber optic socket box is limited; if a splice protection structure is installed for splice repair, it will encroach on cable storage space. Conversely, if cable storage requirements are met, it is difficult to provide reliable protection and a fixed position for splicing operations. Utility Model Content

[0003] The main purpose of this application is to propose a fiber optic socket box that aims to at least solve the problem that existing fiber optic socket box products cannot simultaneously satisfy the needs of redundant cable storage and fiber optic splice fixing and protection.

[0004] To achieve the above objectives, this application proposes a fiber optic socket box, which includes:

[0005] Box body; and

[0006] A positioning shaft is provided on the inner wall of the housing. At least a portion of the positioning shaft is detachably inserted into the shaft hole of the wire storage reel to be installed. The positioning shaft is provided with a snap-fit ​​channel for setting a welding protection sleeve.

[0007] In the technical solution of this application embodiment, the fiber optic socket box integrates both the fiber storage function and the fiber optic splice protection function by providing a positioning shaft with a snap-fit ​​channel on its inner wall. On the one hand, the positioning shaft can be detachably inserted into the shaft hole of the fiber storage tray, enabling the positioning and installation of the fiber storage tray within the fiber optic socket box, thus achieving the coiling and storage of redundant optical fibers. On the other hand, when the fiber storage tray is detached from the positioning shaft, a splice protection sleeve can be directly installed in the snap-fit ​​channel on the positioning shaft, without the need for an additional independent fixing structure for the fiber optic splice. Therefore, within a limited space, the fiber optic socket box simultaneously fulfills the functions of redundant fiber storage and fiber optic splice fixing and protection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] In fiber-to-the-home (FTTH) cabling scenarios, pre-defined patch cords are commonly used for connections. To account for construction errors, a certain amount of redundant cable is usually coiled and stored in the socket box. Meanwhile, the fiber optic connectors attached to these patch cords are prone to end-face contamination or mechanical damage during long-term insertion and removal, requiring on-site repair. Existing repair solutions suffer from insufficient reliability in on-site connector assembly, while replacing the entire patch cord involves a large amount of work and is costly. Furthermore, the internal space of the fiber optic socket box is limited; if a splice protection structure is installed for splice repair, it will encroach on cable storage space. Conversely, if cable storage requirements are met, it is difficult to provide reliable protection and a fixed position for splicing operations.

[0023] In view of this, this application proposes a fiber optic socket box. Figures 1 to 7These are some embodiments of the present application. The fiber optic socket box is applicable to various fiber optic cabling scenarios, including Fiber To The Home (FTTH), Fiber To The Machine (FTTM), Fiber To The Desk (FTTD), Fiber To The Room (FTTR), and Fiber To The Room - Business (FTTR-B).

[0024] Please see Figures 1 to 3 In some embodiments of this application, the fiber optic socket box 1000 includes a box body 1 and a positioning shaft 2. The positioning shaft 2 is disposed on the inner wall of the box body 1. At least a portion of the positioning shaft 2 is detachably inserted into the shaft hole 31 of the cable storage tray 3 to be installed. The positioning shaft 2 is provided with a snap-fit ​​channel 4, which is used to set the fusion splice protection sleeve 16.

[0025] In the technical solution of this application embodiment, the fiber optic socket box 1000 integrates both the fiber storage function and the fiber optic splice protection function on its inner wall by providing a positioning shaft 2 with a snap-fit ​​channel 4. On the one hand, the positioning shaft 2 can be detachably inserted into the shaft hole 31 of the fiber storage tray 3, which can complete the positioning and installation of the fiber storage tray 3 in the fiber optic socket box 1000, so as to realize the coiling and storage of redundant optical fibers. On the other hand, when the fiber storage tray 3 is removed from the positioning shaft 2, the splice protection sleeve 16 can be directly installed in the snap-fit ​​channel 4 on the positioning shaft 2, without the need to add an additional independent fixing structure for the fiber optic splice. Thus, within a limited space, the fiber optic socket box 1000 can simultaneously satisfy the functions of redundant optical fiber storage and fiber optic splice fixing and protection.

[0026] The fixed protection method of the fiber optic fusion splice in this application is described below. When the connector at the end of the prefabricated fiber is damaged and cannot be repaired by cleaning, it is not necessary to replace the entire fiber. Instead, after disconnecting the damaged part, a new pigtail is spliced ​​and the fusion splice is protected by a heat-shrinkable fusion splice protection sleeve 16.

[0027] Specifically, the operator can remove the cable storage tray 3 from the positioning shaft 2 inside the fiber optic socket box 1000, and complete the fusion splicing operation between the pigtail and the original cable in the freed-up space. The heat-shrinkable protective sleeve is then placed in the pre-set snap-fit ​​channel 4 on the positioning shaft 2. This snap-fit ​​channel 4 can effectively fix the fusion splice protective sleeve 16, preventing it from loosening or being stressed.

[0028] Please see Figure 3In some embodiments of this application, two fusion splice protection sleeves 16 are provided, correspondingly, the fiber optic socket box 1000 simultaneously accommodates two fiber optic splices that need protection. This corresponds to a dual-core cabling scenario, such as a drop cable typically containing two fibers, used for different services or to achieve primary / backup redundancy.

[0029] Please see Figure 4 In some embodiments of this application, the box body 1 includes a base 101 and a cover 102. The positioning shaft 2 is disposed on the inner wall of the base 101, and the cover 102 covers the base 101 and provides cover protection for the positioning shaft 2.

[0030] It should be further noted that the limiting method is not the only one during the assembly process of the wire storage reel 3 and the positioning shaft 2: the positioning shaft 2 itself can be used to limit and fix the wire storage reel 3, for example, by using a snap-fit ​​structure; or the wire storage reel 3 can be limited by other auxiliary structures on the cover 102 or the base 101. All of the above implementation methods are within the protection scope of this application, and the specific method can be flexibly selected according to actual production and assembly needs.

[0031] In some embodiments of this application, the positioning shaft 2 has a first end 2A and a second end 2B disposed opposite to each other. The first end 2A is the end connected to the inner wall of the housing 1. The snap-fit ​​channel 4 is an opening that is recessed from the end face of the second end 2B of the positioning shaft 2 into the first end 2A and penetrates through the side of the positioning shaft 2. In this embodiment, since the opening penetrates through the end face of the second end 2B, the operator does not need to perform a sleeve operation and can directly snap the welding protective sleeve 16 into the snap-fit ​​channel 4 from the end face of the second end 2B, which significantly improves the ease of installation during on-site welding operations.

[0032] In some embodiments of this application, the positioning shaft 2 includes a plurality of ring-shaped retaining arms 21 protruding from the inner wall of the housing 1, forming a receiving space 41 between the plurality of retaining arms 21; a retaining gap 42 is formed between two adjacent retaining arms 21, and the engaging channel 4 includes the receiving space 41 and two opposing retaining gaps 42; in this structure, the positioning shaft 2 with a plurality of retaining arms 21 can engage and fix the wire storage tray 3, ensuring the stable installation of the wire storage tray 3, and the hollow receiving space 41 can provide... The fusion splice protection sleeve 16 is inserted to provide a place for the fusion splice protection sleeve 16, while the clamping gap 42 can effectively limit the fusion splice protection sleeve 16, so that the fusion splice protection sleeve 16 can be limited on the positioning shaft 2; that is, the structure of the positioning shaft 2 can simultaneously realize the functions of installing the cable storage tray 3, accommodating and limiting the fusion splice protection sleeve 16, thereby realizing multi-functional integration in a limited space, avoiding the space occupation caused by setting up independent structures for each function, and improving the space utilization and structural compactness of the fiber optic socket box 1000.

[0033] It should be further explained that, since the welding protective sleeve 16 is usually straight, in order to ensure that it can be stably accommodated within the positioning shaft 2 along the straight direction, two opposing clamping gaps 42 need to be formed in this straight direction to effectively limit the ends of the welding protective sleeve 16. Therefore, the number of clamping arms 21 is even, so that two opposing clamping gaps 42 can be formed between the ring-shaped clamping arms 21, ensuring that the welding protective sleeve 16 is evenly supported and fixed in the same straight direction.

[0034] Furthermore, the arrangement of the receiving space 41 provides clearance for the deformation of the holding arm 21, allowing the cable storage reel 3 to be smoothly installed into the shaft hole 31. For example, the holding arm 21 can elastically deform towards the receiving space 41 under external force, thereby allowing the cable storage reel 3 to be pressed in; after the cable storage reel 3 is installed in place, the holding arm 21 elastically returns to its original position, and the latching part on the side opposite to the receiving space 41 can engage the edge of the shaft hole 31 of the cable storage reel 3, achieving a secure engagement of the cable storage reel 3.

[0035] Please see Figure 2 , Figure 3 and Figure 5 In some embodiments of this application, the fiber optic socket box 1000 further includes at least one limiting buckle 5, which is disposed within the snap-fit ​​channel 4 to limit the fusion splice protective sleeve 16. In this embodiment, the limiting buckle 5 can provide auxiliary fixation for the fusion splice protective sleeve 16 inserted into the snap-fit ​​channel 4, preventing it from shifting or coming out when subjected to vibration or external force, further improving the reliability of the fusion splice fixation. Secondly, the limiting buckle 5 and the snap-fit ​​channel 4 work together to enhance the axial and radial limiting ability of the fusion splice protective sleeve 16 without the need to add additional fixing components, making the installation of the fusion splice protective sleeve 16 on the positioning shaft 2 more stable.

[0036] The limiting buckle 5 can be installed within the receiving space 41 to provide auxiliary fixation for the middle part of the welded protective sleeve 16; such as Figure 3 As shown, the limiting buckle 5 can also be provided at the holding gap 42 to limit the end of the welded protective sleeve 16.

[0037] Furthermore, since the two opposing clamping gaps 42 and the receiving space 41 together constitute a clamping channel 4, one or more independent clamping channels 4 can be formed on the positioning shaft 2 by increasing or decreasing the number of clamping arms 21. For example, as shown... Figure 3As shown, two snap-fit ​​channels 4 are provided on the positioning shaft 2, and correspondingly, limit buckles 5 can be provided in each snap-fit ​​channel 4. Since the layout direction of the snap-fit ​​channels 4 can be flexibly adjusted according to the annular arrangement of the clamping arms 21, there is no restriction on the installation angle of the fusion splice protection sleeve 16. Operators can choose a suitable installation position according to the on-site wiring direction, further improving the flexibility of fiber optic cabling.

[0038] Furthermore, within a single locking channel 4, the number of limiting latches 5 can be one or more. For example... Figure 5 As shown, two limiting clips 5 are provided within a snap-fit ​​channel 4, located in two opposite snap-fit ​​gaps 42, with a pre-reserved space between each limiting clip 5 and the adjacent snap-fit ​​arm 21. This design allows the limiting clips 5 and the snap-fit ​​arms 21 on both sides to work together to effectively limit the splice protection sleeve 16, ensuring its stable installation. Simultaneously, this structure also supports the side-by-side installation of two splice protection sleeves 16 within the same snap-fit ​​channel 4, further improving the space utilization of the fiber optic socket box 1000 and its applicability in multi-core fiber scenarios.

[0039] In some embodiments of this application, at least two limiting buckles 5 are provided and are spaced apart along the width direction of the locking channel 4, so that each limiting buckle 5 can independently limit one welded protective sleeve 16. For example, when the limiting buckle 5 is provided in the receiving space 41, it can independently limit and fix the welded protective sleeve 16; when the limiting buckle 5 is provided at the holding gap 42, it can cooperate with the adjacent holding arm 21 to jointly clamp and limit the welded protective sleeve 16.

[0040] Please see Figure 3 and Figure 6 In some embodiments of this application, the limiting buckle 5 is disposed within the holding gap 42 and includes a main body 51 and a buckle protrusion 52. The main body 51 is fixed to the positioning shaft 2, and the buckle protrusion 52 is disposed on the side of the main body 51 near the adjacent holding arm 21, so that the gap between the limiting buckle 5 and the holding arm 21 has a structural feature of being larger at the bottom and smaller at the top in the direction away from the base 101, that is, the opening end is narrower and the bottom is wider, so as to form an effective anti-detachment limiting for the welding protective sleeve 16, making it difficult for the welding protective sleeve 16 to slide out towards the second end 2B of the positioning shaft 2 after installation.

[0041] In some embodiments of this application, the limiting buckle 5 is capable of elastic deformation. Two adjacent limiting buckles 5 are spaced apart, so that the gap between them forms a clearance space 17, making it easier for the limiting buckle 5 to undergo elastic deformation when subjected to external force, thereby providing deformation margin for the welding protective sleeve 16 to smoothly enter the gap between the limiting buckle 5 and the adjacent holding arm 21.

[0042] It should be noted that the positioning shaft 2 is installed on the inner wall of the box 1. The connection method can be either a fixed connection, such as by integral molding or fasteners, or a non-fixed connection, such as by snap-fit ​​or plug-in to achieve detachable installation.

[0043] In some embodiments of this application, the fiber optic socket box 1000 further includes a chassis 6, and the positioning shaft 2 is detachably mounted on the inner wall of the box body 1 via the chassis 6; in this embodiment, the positioning shaft 2 and the box body 1 are detachably connected via the chassis 6, which makes it convenient for operators to replace the positioning shaft 2 of different specifications or structures according to on-site needs.

[0044] The specific form of the detachable connection is not limited and can be flexibly selected according to actual production and assembly needs, such as using snap-fit, plug-in, threaded connection or magnetic adsorption.

[0045] In some embodiments of this application, the inner wall of the box body 1 is provided with a groove 7, and at least one stop 8 is formed at the opening of the groove 7; the chassis 6 is accommodated in the groove 7, and the stop 8 restricts the chassis 6 from being dislodged from the groove 7; in this embodiment, the cooperation between the groove 7 and the stop 8 can effectively accommodate and limit the chassis 6, ensuring that the chassis 6 is firmly installed in the box body 1, avoiding displacement or dislodging of the chassis 6 due to vibration or external pulling, and improving the reliability of the overall structure.

[0046] Furthermore, this structural design allows for the rapid installation and fixation of the chassis 6 onto the housing 1 without the need for additional fasteners.

[0047] Please see Figure 2 In some embodiments of this application, a plurality of stop portions 8 are provided around the periphery of the groove 7. The plurality of stop portions 8 are distributed at intervals along the periphery of the groove 7, which can form a uniform limiting force on the chassis 6 from multiple directions, effectively preventing the chassis 6 from shifting or coming off in any direction, and significantly improving the stability of the chassis 6.

[0048] In some embodiments of this application, the side surface of the stop portion 8 away from the bottom of the groove 7 along the groove depth direction is set as an inclined surface. Simultaneously, at least one of the stop portion 8 and the chassis 6 is capable of elastic deformation. During assembly, the chassis 6 can be easily inserted into the groove 7 by being guided by the inclined surface and undergoing elastic deformation, making the operation simple. After insertion, the side surface of the stop portion 8 near the bottom of the groove 7 is parallel or nearly parallel to the bottom plane of the groove 7, thereby forming a stop in the groove depth direction and effectively preventing the chassis 6 from detaching from the groove 7.

[0049] In some embodiments of this application, the chassis 6 is rotatably and adjustablely mounted on the groove 7 so as to adjust the orientation of the snap-fit ​​channel 4. In this embodiment, by rotating the chassis 6, the operator can flexibly adjust the orientation of the snap-fit ​​channel 4 on the positioning shaft 2 according to the fiber introduction direction or wiring layout, so that the installation angle of the fusion splice protection sleeve 16 is more adapted to the actual wiring requirements, and the flexibility of operation is improved.

[0050] Meanwhile, the rotatable and adjustable chassis 6 design avoids fiber optic bending or inconvenient wiring caused by the fixed direction of the snap-fit ​​channel 4, which helps to optimize the bending radius of the fiber optic cable and ensure signal transmission performance.

[0051] For example, in one embodiment of this application, the groove 7 is circular, and the chassis 6 is also configured as a circular structure adapted to it, so that the chassis 6 can rotate within the groove 7.

[0052] Please see Figure 6 In some embodiments of this application, the bottom of the groove 7 is provided with a mating part 9, and the chassis 6 is provided with a positioning part 10 that mates with the mating part 9. One of the positioning part 10 and the mating part 9 is a positioning protrusion, and the other is a positioning groove. In this embodiment, the mating part 10 and the positioning groove are engaged to position the chassis 6 after it has been rotated and adjusted to the correct position. This prevents the chassis 6 from rotating on its own due to vibration or external force and changing the orientation of the snap-fit ​​channel 4, thus ensuring the stability of the installation direction of the welding protective sleeve 16.

[0053] The specific forms of the positioning part 10 and the mating part 9 can be flexibly interchanged: the positioning part 10 can be a positioning protrusion and the mating part 9 can be a positioning groove, or the positioning part 10 can be a positioning groove and the mating part 9 can be a positioning protrusion.

[0054] To facilitate easier insertion of the positioning protrusion into the positioning groove during rotation, at least a portion of the surface of the positioning protrusion is configured with an arcuate structure. For example, as... Figure 6 As shown, the positioning protrusion can be set to a hemispherical shape.

[0055] In some embodiments of this application, at least one of the mating part 9 and the positioning part 10 is configured as a plurality and distributed circumferentially along the positioning axis 2. The mating part 9 can selectively engage with the positioning part 10 to restrict the chassis 6 to multiple positions along its rotational stroke. In this embodiment, the plurality of mating parts 9 or positioning parts 10 are distributed circumferentially, so that the chassis 6 can be positioned at multiple preset angle positions during rotation. The operator can select the appropriate orientation of the snap-fit ​​channel 4 according to the on-site wiring requirements.

[0056] For example, when there are multiple positioning grooves, there can also be multiple positioning protrusions, so that multiple mating points are formed between the chassis 6 and the groove 7, thereby improving the connection stability between the chassis 6 and the groove 7.

[0057] In some embodiments of this application, the groove 7 has an elastic deformation part 11, and the mating part 9 is disposed on the elastic deformation part 11. In this embodiment, by providing the elastic deformation part 11, the mating part 9 can elastically avoid the chassis 6 during rotation, avoiding jamming or interference between the mating part 9 and the positioning part 10 due to rigid contact, ensuring the smoothness of chassis 6 rotation adjustment. When the chassis 6 rotates to the target position, the elastic deformation part 11 can use its elastic restoring force to make the mating part 9 automatically engage with the positioning part 10, thereby achieving automatic positioning of the chassis 6.

[0058] It should be noted that the specific configuration of the elastic deformation part 11 is not limited and can be flexibly selected according to actual design requirements. For example, elastic structures such as elastic pads, springs, elastic sheets, and elastic arms 111 can be used.

[0059] Please see Figures 6 to 7 In some embodiments of this application, the wall of the groove 7 is provided with an opening 12, and the elastic deformation part 11 includes an elastic arm 111 disposed in the opening 12. One end of the elastic arm 111 is connected to the side wall of the opening 12, and the other end is cantilevered. The mating part 9 is disposed on the cantilever of the elastic arm 111. In this embodiment, the elastic deformation part 11 is set as an elastic arm 111 so that the mating part 9 can elastically avoid the rigid interference with the positioning part 10 during the rotation of the chassis 6, thus ensuring the smoothness of the rotation adjustment of the chassis 6. When the chassis 6 rotates to the target position, the elastic arm 111 uses its elastic restoring force to make the mating part 9 automatically engage with the positioning part 10, thereby achieving automatic locking of the chassis 6 and automatic positioning of the chassis 6.

[0060] The groove 7 has an opening 12 on its wall and an elastic arm 111. This ensures that the mating part 9 can flexibly avoid obstacles, and that the chassis 6 can be smoothly adjusted and automatically locked. At the same time, it also effectively reduces the amount of material used in the fiber optic socket box 1000.

[0061] In some embodiments of this application, the housing 1 is provided with a plurality of adapter mounting portions 14 in a direction away from its communication interface 13; each adapter mounting portion 14 is provided with at least one guide rail 141, the guide rail 141 being used to guide the fiber optic adapter 15 to be installed to the corresponding adapter mounting portion 14; in this embodiment, the structure of the plurality of adapter mounting portions 14 allows the fiber optic adapter 15 to have multiple selectable installation positions within the housing 1, and the operator can install the fiber optic adapter 15 onto the corresponding adapter mounting portion 14 via the corresponding guide rail 141 according to different usage requirements.

[0062] For example, when frequent plugging and unplugging or quick wiring is required, operators can install the fiber optic adapter 15 in an exposed position near the communication interface 13, enabling operation without opening the cover and improving ease of use. When using relatively weak fiber optic cables such as transparent cables or indoor cables, the fiber optic adapter 15 can be installed internally. The internal installation not only provides basic wiring capabilities, but more importantly, it ensures that the fiber optic cable is close to the wall or attached surface when it is led out of the fiber optic socket box 1000. Compared to installing the fiber optic adapter 15 in an exposed position near the communication interface 13, this design ensures that the fiber optic cable is tightly attached to the surface from the lead-out point, greatly improving the aesthetics and reliability of indoor wiring and effectively avoiding accidental pulling and mechanical damage caused by the fiber optic cable being suspended or exposed.

[0063] Finally, it should be noted that the object secured by the snap-fit ​​channel 4 is not limited to the fusion splice protection sleeve 16 exemplified in the aforementioned embodiments. In practical applications, the snap-fit ​​channel 4 is also suitable for securing other forms of fiber optic splice protection structures, such as mechanical fiber optic splice protection structures, or directly for securing mechanical cold joints. Furthermore, various protection structures can be arbitrarily combined and placed within the snap-fit ​​channel 4 according to site requirements. This application does not impose any limitations on this; as long as the repair fiber can be secured through the snap-fit ​​channel 4, it falls within the scope of protection of this application.

[0064] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
