Detailed Description of the Embodiments

[0035] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals denote the same or similar components or components with the same or similar functions throughout. The described embodiments are some but not all of the embodiments of the present application. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as a limitation to the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0036] In the description of the present application, it should be noted that, unless otherwise clearly specified and defined, the terms "mounted", "connected", and "connected" should be understood in a broad sense. For example, it may be a fixed connection, or an indirect connection through an intermediate medium, or the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0037] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0038] The terms "first", "second", "third", "fourth", etc. in the description and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein, for example, can be implemented in an order other than those illustrated or described herein.

[0039] In addition, the terms "comprising", "having", and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0040] As described in the background art, in rail transit scenarios such as high-speed railways and subways, the continuous vibration generated by the operation of high-speed trains easily causes the optical fiber in the optical cable splice enclosure to vibrate and fail, affecting the optical signal transmission. Therefore, in an environment with frequent vibrations, more frequent maintenance and inspections are also required, increasing the maintenance cost.

[0041] In a conventional optical cable splice enclosure structure, in an environment with high-frequency vibrations, it is easy to cause the screws of the optical cable splice enclosure to loosen, and the sealing performance of the enclosure decreases, resulting in situations such as water ingress and icing, damaging the optical fiber, and being unable to meet the usage requirements of special application environments. Based on this, in related technologies, a buffer rubber layer or sponge layer is generally laid under the optical cable splice enclosure. However, the service life of the cushioning material is limited and needs to be frequently replaced, and non-uniform compression deformation will occur after the cushioning material is loaded, resulting in local stress concentration at the bottom of the optical cable splice enclosure, which may cause optical fiber microbending loss or encapsulation layer peeling.

[0042] Based on the above related descriptions, in one or more embodiments of the present application, an anti-vibration bracket for an optical cable splice enclosure and an optical cable connection device are provided. The solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0043] As Figure 1 and Figure 2 shown, an anti-vibration bracket for an optical cable splice enclosure is provided in an embodiment of the present application, which includes a bracket body 100, a buffer member 200, and a mounting member 300.

[0044] A set of support members 101 are respectively arranged on opposite sides of the bracket body 100. The buffer member 200 is elastically connected to the bracket body 100. The buffer member 200 is located between the two sets of support members 101 and is configured to elastically displace along the extension direction of the support members 101. The buffer member 200 is used to mount the optical cable splice enclosure 400; the mounting member 300 is connected to the support members 101 to slide and displace along the extension direction of the support members 101. There is a gap between the mounting member 300 and the buffer member 200. The mounting member 300 is used to fix the optical cable extending from the optical cable splice enclosure 400.

[0045] From the above description, it can be seen that in the anti-vibration bracket for an optical cable splice enclosure provided in the embodiment of the present application, in the anti-vibration bracket for an optical cable splice enclosure, the buffer member 200 is elastically connected to the bracket body 100, and the buffer member 200 uses elastic displacement to absorb the impact force and energy of track vibration, avoiding direct impact of track vibration on the optical cable splice enclosure 400.

[0046] In addition, the sliding connection between the mounting member 300 and the support member 101 enhances the flexibility of the mounting member 300. There is a gap between the mounting member 300 and the buffer member 200. The mounting member 300 fixes the optical cable extending from the optical cable joint box 400. While the buffer member 200 undergoes elastic displacement, the vibration of the external cable will drive the mounting member 300 to perform synchronous sliding displacement. The vibration impact of the external optical cable is buffered and absorbed by the mounting member 300, thereby reducing the impact of the external optical cable vibration on the optical cable joint box 400 and facilitating the stable connection of the optical cable joint box 400.

[0047] It should be noted that the anti-vibration bracket for the optical cable joint box can be wall-mounted in the trough through bolts or directly floor-mounted on the trough floor with bolts. For different installation scenarios, the installation method of the anti-vibration bracket can be adjusted accordingly. In addition, the orientation terms such as "up and down", "horizontal", and "vertical" mentioned in the embodiments of the present application are described with reference to the orientation of the anti-vibration bracket installed in the trough. Generally, the optical cable joint box 400 is located on the buffer member 200, and the support member 101 extends along the height direction.

[0048] As Figure 2 shown, in the embodiment of the present application, the bracket body 100 includes a bottom frame 102, the support member 101 is arranged on the bottom frame 102, and a plurality of elastic components 103 are arranged at intervals on the bottom frame 102. The buffer member 200 is horizontally supported on the elastic components 103.

[0049] The bottom frame 102 in the above embodiment is a rectangular frame. Both the bottom frame 102 and the support member 101 are made of metal materials, such as steel plates or iron plates. The bottom frame 102 and the support member 101 are connected by welding to ensure the stable connection of the bracket body 100 and the support member 101. Here, the support member 101 can adopt a support column or other columnar support structures, and the buffer member 200 can adopt a flat plate-like structure, as long as it can support the optical cable joint box 400. There is no absolute limitation in this regard in the embodiments of the present application.

[0050] The buffer member 200 is integrally supported on a plurality of elastic components 103. The plurality of elastic components 103 are spaced apart on the bottom frame 102 to form a multi-point discontinuous support structure. Thus, the vibration load can be evenly distributed to a plurality of independent elastic components 103 to avoid local vibration.

[0051] Further, the above elastic component 103 includes a support rod 1031 and an elastic member 1032 sleeved in the support rod 1031. One end of the support rod 1031 is connected to the bottom frame 102, and the other end is connected to the buffer member 200. The elastic member 1032 is clamped between the buffer member 200 and the bottom frame 102.

[0052] The above elastic member 1032 can be a metal steel spring. The support rod 1031 and the elastic member 1032 form an axial guiding constraint. The support rod 1031 restricts the elastic member 1032 to only undergo compressive or popping deformations in the axial direction. For complex vibration scenarios where the direction of vibration energy is uncertain, by guiding the elastic deformation direction of the elastic member 1032 through the support rod 1031, it can ensure that the vibration energy is efficiently transmitted along the axis of the support rod 1031 to the elastic member 1032, thereby using the elastic member 1032 to absorb the vibration energy and enhancing the buffering effect of the elastic member 1032.

[0053] In the embodiment of the present application, the support rod 1031 has an installation end that penetrates through the buffer member 200, and a fixing member 1033 for preventing the buffer member 200 from detaching from the support rod 1031 is connected to the installation end. The position of the fixing member 1033 on the support rod 1031 is adjustable to adjust the pre-compression amount of the elastic member 1032.

[0054] Here, a threaded fit connection can be adopted between the fixing member 1033 and the support rod 1031. To ensure that the position of the fixing member 1033 on the support rod 1031 does not shift due to vibration, the fixing member 1033 is a self-locking nut member. The deeper the fixing member 1033 is screwed into the support rod 1031, the greater the pre-compression amount of the elastic member 1032. When the fixing member 1033 is screwed into the support rod 1031 at a shallower position, the pre-compression amount of the elastic member 1032 is smaller.

[0055] By regulating the pre-compression amount of the elastic member 1032, the overall stiffness coefficient and damping threshold of the anti-vibration bracket can be adjusted. For example, in the high-frequency vibration section of track and channel wheel-rail resonance, appropriately increasing the pre-compression amount of the elastic member 1032 enables the elastic member 1032 to be in the medium-high stiffness range to suppress the transmission of micro-amplitude high-frequency vibrations; for the low-frequency large-amplitude scenario of a bridge, appropriately reducing the pre-compression amount releases the flexible space of the elastic member 1032 to facilitate the elastic member 1032 to absorb a large amount of impact energy.

[0056] In some embodiments, the staff can directly adjust the pre-compression amount of the elastic member 1032 by rotating the fixing member 1033 without having to remove the optical cable splice box 400 or interrupt fiber optic communication, which is beneficial for on-site rapid adjustment and maintenance. In addition, after being used for a period of time, the elastic life of the elastic member 1032 decays. When the staff performs regular maintenance, they can directly increase the pre-compression amount of the elastic member 1032 to ensure the normal elastic potential energy of the elastic member 1032, so that the elastic member 1032 is always in a stable and normal elastic telescopic state and does not need to be replaced for a period of time. This design is convenient for maintenance and can reduce the maintenance cost.

[0057] In some embodiments, a distance scale is further provided on the support column. For example, the distance is demarcated at intervals of 0.5 mm. The distance scale extends from the area where the elastic member 1032 is located to the installation end side of the buffer member 200 passing through. The staff can determine the pre-compression amount of the spring by observing through the distance scale, so as to facilitate adjusting the pre-compression amounts of the plurality of elastic components 103 and making the pre-compression amounts of the plurality of elastic components 103 consistent. Of course, observing and adjusting the pre-compression amount of the elastic component 103 through the distance scale is based on the premise that the materials, dimensions, and elastic parameters of the elastic members 1032 used in each elastic component 103 are the same. This design can ensure that the buffer member 200 is always in a horizontal state, thereby ensuring the horizontal stability of the optical cable splice case 400.

[0058] In addition, after long-term service, the elastic member 1032 undergoes permanent deformation due to metal fatigue. During daily inspection and maintenance, the staff can directly judge whether the elastic member 1032 has a risk of failure by observing the offset amount of the elastic member 1032 on the distance scale, avoiding the sudden fracture of the elastic member 1032 resulting in the fall of the optical cable splice case 400 along with the buffer member 200.

[0059] As Figure 3 and Figure 4 shown, in the anti-vibration bracket of the optical cable splice case of the embodiment of the present application, a limiting component 301 for clamping the optical cable is provided on the mounting member 300, and the limiting component 301 is used to limit the axial displacement of the optical cable extending out of the optical cable splice case 400.

[0060] In the above embodiment, a chute extending in the height direction is provided on the support member 101, and a bolt member is passed through the mounting member 300 and is limited in the chute. When adjusting the tightness of the bolt member in the chute, the sliding or locking state of the mounting member 300 and the support member 101 can be adjusted accordingly, constituting a sliding connection between the mounting member 300 and the support member 101. Of course, other sliding connection structures can also be adopted between the mounting member 300 and the support member 101, and only examples are given in the embodiment of the present application.

[0061] The mounting member 300 is exemplarily an "L"-shaped metal plate member. Specifically, the limiting component 301 includes a first card slot 3011 fixed on the mounting member 300 and a second card slot 3012 detachably connected to the first card slot 3011. The first card slot 3011 and the second card slot 3012 enclose a receiving cavity for passing the optical cable; among them, a protruding limiting member 3013 is provided on one side of the first card slot 3011 and / or the second card slot 3012 for abutting against the optical cable, and the limiting member 3013 blocks the axial displacement of the optical cable.

[0062] The receiving cavity enclosed by the first card slot 3011 and the second card slot 3012 is approximately elliptical. This design is convenient for adapting to optical cables of different diameters and improving the versatility of the limiting component 301.

[0063] Preferably, limiting members 3013 are provided in both the first card slot 3011 and the second card slot 3012. Taking the first card slot 3011 as an example, the limiting member 3013 is a flexible pad clamped between the first card slot 3011 and the optical cable. The limiting member 3013 can be made of a rubber material, a silicone material or an engineering plastic material with a certain elasticity.

[0064] The side of the flexible pad for abutting against the optical cable has serrated protrusions 3015, and a plurality of convex points 3016 are arranged at intervals on the serrated protrusions 3015. The serrated protrusions 3015 and the convex points 3016 cooperate to embed into the surface of the outer sheath of the optical cable, thereby forming a local stress concentration area of the optical cable. In a vibration scenario, the axial slip of the optical cable is offset by the engagement and limitation between the limiting member 3013 and the optical cable.

[0065] Furthermore, as Figure 5 shown, a through hole 3014 is provided on the first card slot 3011, and a convex column for passing through the through hole 3014 is constructed on the limiting member 3013. The convex column is embedded in the through hole 3014 to fixedly connect the limiting member 3013 and the first card slot 3011. This design can further improve the fixing effect between the limiting member 3013 and the first card slot 3011, and prevent the limiting member 3013 from deviating from the first card slot 3011 due to vibration.

[0066] In addition, in some embodiments, serrated protrusions 3015 and convex points 3016 are also constructed on the side of the first card slot 3011 facing the limiting member 3013. The serrated protrusions 3015 and convex points 3016 on the first card slot 3011 cooperate with the serrated protrusions 3015 and convex points 3016 on the limiting member 3013 to enhance the limiting effect between the first card slot 3011 and the limiting member 3013.

[0067] It should be noted that in the embodiments of the present application, a limiting member 3013 is fixedly connected by clamping in both the first card slot 3011 and the second card slot 3012. The two limiting members 3013 jointly clamp the opposite sides of the optical cable and block the axial displacement of the optical cable.

[0068] Through the above settings, the limiting component 301 on the anti-vibration bracket of the optical cable joint box directly bears the axial tension of the external optical cable, avoiding the direct action of the axial force of the external optical cable on the inside of the optical cable joint box 400 and affecting the shock absorption effect.

[0069] Meanwhile, since the mounting member 300 is movably connected to the support member 101, the limiting component 301 on the mounting member 300 fixes the optical cable extending from the optical cable splice box 400. Thus, when the external optical cable is affected by environmental vibration, it first impacts the limiting component 301 on the mounting member 300, and the impact energy is absorbed and released by the up-and-down movement of the mounting member 300, reducing the impact of the external optical cable on the internal structure of the optical cable splice box 400. In addition, since the mounting member 300 is movably connected to the support member 101, the actual height of the mounting member 300 can be adjusted arbitrarily, facilitating the matching of optical cable splice boxes 400 of different sizes and specifications without the need to design dedicated optical cable splice boxes 400 for different sizes and specifications, with strong versatility.

[0070] In some embodiments, as Figure 2 shown, a mounting member 300 is respectively connected to each group of support members 101. Each group of support members 101 has two spaced apart ones, and both ends of the mounting member 300 are slidably connected to a support member 101.

[0071] Figure 2 When the bottom frame 102 is a rectangular frame, a total of four support members 101 are fixed on the bottom frame 102. Each group of support members 101 slidably connects a mounting member 300, and the mounting member 300 is restricted by the two support members 101 to slide only along the axial direction of the support member 101, avoiding lateral swing when a support member 101 is connected to the mounting member 300 on one side only. And a mounting member 300 is respectively arranged on two groups of support members 101 on opposite sides. The heights of the two mounting members 300 are not necessarily the same. This design also facilitates the adaptation to various different vibration scenarios, enabling the cables extending from opposite sides of the optical cable splice box 400 to have a certain vibration redundancy, reducing the impact of the extending cables on the optical cable splice box 400.

[0072] It should be noted that in the embodiments of the present application, the mounting member 300 is detachably connected to the support member 101, the buffer member 200 is detachably connected to the optical cable splice box 400, the buffer member 200 is detachably connected to the bottom frame 102, and there is an accommodation space 201 between the buffer member 200 and the bottom frame 102.

[0073] In the above embodiments, exemplarily, the mounting member 300 and the support member 101 are connected by a bolt member passing through them, the buffer member 200 and the optical cable splice box 400 are connected by a bolt member passing through both of them, and the buffer member 200 and the bottom frame 102 are connected by an elastic component 103. Thus, the above buffer member 200 is easier to disassemble and assemble.

[0074] Compared with directly arranging the optical cable joint box 400 on the cable duct in the related art, the design of the accommodating space 201 utilizes the space originally occupied by the optical cable joint box 400 to lay communication cables, power cables, etc., making full use of the installation space of the anti-vibration bracket. In addition, the accumulated water at the bottom of the cable duct can be discharged through the accommodating space 201 of the anti-vibration bracket, avoiding the influence of the accumulated water in the cable duct on the optical cable joint box 400. Moreover, the design of the accommodating space 201 forms a channel allowing air flow under the anti-vibration bracket, which can accelerate the heat dissipation of the optical cable joint box 400.

[0075] The embodiment of the present application further provides an optical cable connection device, including an optical cable joint box 400 and the optical cable joint box anti-vibration bracket in any of the above embodiments connected to the optical cable joint box 400. Since the optical cable connection device includes the optical cable joint box anti-vibration bracket in any of the above embodiments, it has all the advantages of the optical cable joint box anti-vibration bracket.

[0076] As Figure 6 and Figure 7 shown, in some embodiments, along the conveying direction of the optical cable, at least two groups of fiber splicing tray assemblies are spaced in the optical cable joint box 400, and each fiber splicing tray assembly includes a plurality of stacked fiber splicing trays 401, and the plurality of fiber splicing trays 401 are connected by a common installation shaft 404 passing through.

[0077] Generally, three fiber splicing tray assemblies are provided in the above embodiments, and the three fiber splicing tray assemblies can adopt the same structural design. Taking one of the fiber splicing tray assemblies as an example, each fiber splicing tray assembly includes a plurality of stacked fiber splicing trays 401, and the plurality of fiber splicing trays 401 are fixed on the outer shell 402 of the optical cable joint box 400 through a common installation shaft 404 passing through. The upper end of the installation shaft 404 is threadedly matched with a nut to fasten the plurality of fiber splicing trays 401, avoiding gaps between the plurality of fiber splicing trays 401, thereby preventing the fiber splicing trays 401 from being damaged by vibration.

[0078] In the related art, the plurality of fiber splicing trays 401 are generally connected by a side shaft in a rotational connection manner, and the fiber splicing trays 401 are flipped for assembly and maintenance work. However, the rotational connection of the side shaft is affected by vibration, causing adjacent two fiber splicing trays 401 to collide with each other, easily resulting in the connection failure of the fiber splicing trays 401. Based on this, by passing a common installation shaft 404 through the plurality of fiber splicing trays 401, the problem of the fiber splicing trays 401 falling off caused by vibration can be effectively avoided.

[0079] In some embodiments, a buffer pad is clamped between two adjacent fiber splicing trays 401, and the buffer pad can be a sponge pad or a silica gel pad, etc., to further improve the seismic resistance effect of the fiber splicing trays 401.

[0080] In addition, since multiple fiber splicing tray assemblies are provided in the embodiments of the present application, each fiber splicing tray assembly can be respectively installed with optical cables of corresponding operators. For example, the optical cables of China Mobile, China Unicom, and China Telecom are respectively installed in three fiber splicing tray assemblies. The three operators are connected independently in separate areas. During the construction and maintenance process, only the area where the target fiber splicing tray assembly is located needs to be opened, without affecting the normal transmission of the optical fibers of other operators, without interference with each other, and there will be no problem of cross-maintenance. This improves the fiber density in the optical cable splice closure 400 and effectively improves the space utilization rate of the optical cable splice closure 400.

[0081] It should be noted here that there should be a certain gap between two adjacent fiber splicing tray assemblies. This gap should be sufficient to block the electromagnetic interference between the optical fibers of different operators. For actual application scenarios, this gap can be flexibly adjusted. In addition, different fiber splicing tray assemblies can correspond to exclusive identifiers or colors of the operators. For example, the red fiber splicing tray assembly corresponds to China Mobile, the blue fiber splicing tray assembly corresponds to China Unicom, and the yellow fiber splicing tray assembly corresponds to China Telecom, etc. Together with the QR code label, it can quickly locate the ports. This is not elaborated in the embodiments of the present application.

[0082] As Figure 7 shown, in some embodiments, the optical cable splice closure 400 includes an outer housing 402 and a support plate 403 disposed in the outer housing 402. The support plate 403 is used to support the fiber splicing tray assembly, and the outer housing 402 and the support plate 403 are elastically connected.

[0083] The above-mentioned elastic connection between the support plate 403 and the outer housing 402 can refer to the above-mentioned elastic component 103 method. Exemplarily, a connecting column 405 is connected between the support plate 403 and the outer housing 402, and a spring is sleeved on the connecting column 405 to form an elastic connection between the support plate 403 and the outer housing 402 by using the spring. Of course, the connecting columns 405 can be arranged at intervals along the circumferential direction of the support plate 403, and the support plate 403 is supported by the connecting columns 405 and the springs sleeved on the connecting columns 405.

[0084] The elastic connection between the support plate 403 and the outer housing 402 can reduce the vibration of the fiber splicing tray 401 on the support plate 403, thereby further improving the seismic resistance effect of the fiber splicing tray 401.
