Description

Technical Field

[0001] This application relates to communication equipment technology, and more particularly to an anti-vibration bracket for an optical cable junction box and an optical cable connection device. Background Technology

[0002] Optical fiber splice closures are key equipment in the communications industry used to connect and protect optical fiber splices. Their core function is to achieve physical connection of multiple optical cables and continuity of signal transmission, while also providing mechanical protection, sealing and moisture protection, and organization and storage for the optical fiber splices.

[0003] In rail transit scenarios such as high-speed rail and subway, the continuous vibration generated by the operation of high-speed trains can easily cause the optical fiber in the optical cable junction box to vibrate and fail, affecting the transmission of optical signals. It can also cause the fusion splice in the optical cable junction box to fall off and damage the optical fiber. Summary of the Invention

[0004] This application provides an anti-vibration bracket for an optical cable splice box and an optical cable connection device to solve the problem that optical cable splice boxes are prone to failure due to vibration in related technologies.

[0005] On the one hand, this application provides a vibration-damping bracket for an optical cable splice closure, comprising:

[0006] The support body has a set of support members on each of its opposite sides;

[0007] A buffer element is elastically connected to the support body. The buffer element is located between the two sets of support elements and is configured to elastically displace along the extension direction of the support elements. The buffer element is used to install an optical cable junction box.

[0008] The mounting component is connected to the support component to slide along the extension direction of the support component. There is a gap between the mounting component and the buffer component. The mounting component is used to fix the optical cable extending from the optical cable junction box.

[0009] In some possible implementations, the support body includes a bottom frame, the support member is disposed on the bottom frame, a plurality of elastic components are spaced apart on the bottom frame, and the buffer member is horizontally supported on the elastic components.

[0010] In some possible implementations, the elastic component includes a support rod and an elastic element sleeved in the support rod, one end of the support rod being connected to the bottom frame and the other end being connected to the buffer, and the elastic element being sandwiched between the buffer and the bottom frame.

[0011] In some possible implementations, the support rod has a mounting end that extends through the buffer member, and the mounting end is connected to a fixing member that prevents the buffer member from detaching from the support rod. The position of the fixing member on the support rod is adjustable to adjust the pre-compression of the elastic member.

[0012] In some possible implementations, the mounting component is provided with a limiting component for engaging the optical cable, the limiting component being used to limit the axial displacement of the optical cable extending from the optical cable junction box.

[0013] In some possible implementations, the limiting component includes a first slot fixed to the mounting member and a second slot detachably connected to the first slot, the first slot and the second slot forming a receiving cavity through which the optical cable passes;

[0014] The first slot and / or the second slot are provided with a protruding limiting member on one side of the optical cable, and the limiting member prevents the optical cable from moving in the axial direction.

[0015] In some possible implementations, each set of the support members is connected to a mounting member, and each set of the support members has two members spaced apart. The two ends of the mounting member are slidably connected to one of the support members.

[0016] In some possible implementations, the mounting member is detachably connected to the support member, the buffer member is detachably connected to the optical cable junction box, the buffer member is detachably connected to the bottom frame, and there is a receiving space between the buffer member and the bottom frame.

[0017] On the other hand, this application provides an optical cable connection device, including an optical cable junction box and an anti-vibration bracket for the optical cable junction box as described in any of the preceding claims, which is connected to the optical cable junction box.

[0018] In some possible implementations, along the direction of optical cable transport, the optical cable junction box is provided with at least two sets of fiber fusion splice tray assemblies at intervals, each of the fiber fusion splice tray assemblies including multiple stacked fiber fusion splice trays, and the multiple fiber fusion splice trays are connected by a common mounting shaft.

[0019] In some possible implementations, the optical cable junction box includes an outer shell and a support plate disposed in the outer shell, the support plate being used to support the fiber fusion splice assembly, and the outer shell and the support plate being elastically connected.

[0020] The anti-vibration bracket and optical cable connection device for optical cable splice boxes provided in this application utilize a buffer component that is elastically connected to the bracket body. The buffer component absorbs the impact force and energy of track vibration through elastic displacement, preventing track vibration from directly impacting the optical cable splice box. In addition, the mounting component and the support component are slidably connected, and there is a gap between the mounting component and the buffer component. When the mounting component fixes the optical cable extending from the optical cable splice box, the vibration impact of the external optical cable is slowed down and absorbed by the mounting component, thereby reducing the impact of external optical cable vibration on the optical cable splice box and helping to ensure the connection stability of the optical cable splice box.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

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

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In the description of this application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0038] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0039] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0040] As mentioned in the background technology, in rail transit scenarios such as high-speed rail and subway, the continuous vibration generated by the operation of high-speed trains can easily cause the optical fiber in the optical cable junction box to vibrate and fail, affecting the transmission of optical signals. Therefore, in the frequent vibration environment, more frequent maintenance and repair are required, increasing maintenance costs.

[0041] Conventional fiber optic splice closure structures are prone to screw loosening and reduced sealing performance under high-frequency vibration, leading to water ingress, icing, and damage to the optical fiber, thus failing to meet the requirements of special application environments. Therefore, related technologies typically place a cushioning rubber or sponge layer under the splice closure. However, the lifespan of this cushioning material is limited, requiring frequent replacement. Furthermore, the cushioning material undergoes non-uniform compressive deformation under load, causing localized stress concentration at the bottom of the splice closure, potentially leading to microbending loss in the optical fiber or delamination of the encapsulation layer.

[0042] Based on the above description, one or more embodiments of this application provide an anti-vibration bracket for an optical cable junction box and an optical cable connection device. The following describes the solutions of the embodiments of this application in conjunction with the accompanying drawings.

[0043] like Figure 1 and Figure 2 As shown in the figure, this application provides a vibration-damping bracket for an optical cable junction box, including a bracket body 100, a buffer 200, and an installation component 300.

[0044] A set of support members 101 is provided on each of the opposite sides of the bracket body 100. A 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 member 101. The buffer member 200 is used to install the optical cable junction box 400. The mounting member 300 is connected to the support member 101 and slides along the extension direction of the support member 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 junction box 400.

[0045] As can be seen from the above description, the optical cable junction box vibration-damping bracket provided in this application embodiment utilizes a buffer 200 that is elastically connected to the bracket body 100. The buffer 200 absorbs the impact force and energy of track vibration through elastic displacement, thus preventing track vibration from directly impacting the optical cable junction box 400.

[0046] Furthermore, the sliding connection between the mounting component 300 and the support component 101 enhances the flexibility of the mounting component 300. There is a gap between the mounting component 300 and the buffer component 200. The mounting component 300 fixes the optical cable extending from the optical cable junction box 400. While the buffer component 200 is elastically displaced, the vibration of the external cable will drive the mounting component 300 to slide synchronously. The vibration impact of the external optical cable is slowed and absorbed by the mounting component 300, thereby reducing the impact of the external optical cable vibration on the optical cable junction box 400, which is conducive to ensuring the connection stability of the optical cable junction box 400.

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

[0048] like Figure 2 As shown in the embodiment of this application, the bracket body 100 includes a bottom frame 102, a support member 101 is disposed on the bottom frame 102, a plurality of elastic components 103 are spaced apart on the bottom frame 102, and a buffer member 200 is horizontally supported on the elastic components 103.

[0049] In the above embodiment, the bottom frame 102 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 a stable connection between the bracket body 100 and the support member 101. Here, the support member 101 can be a support column or other columnar support structure, and the buffer member 200 can be a flat plate structure, as long as it can support the optical cable junction box 400. This embodiment does not impose an absolute limitation on this.

[0050] The buffer 200 is supported on multiple elastic components 103. The multiple elastic components 103 are distributed at intervals on the bottom frame 102 to form a multi-point discontinuous support structure. As a result, the vibration load can be evenly distributed to multiple independent elastic components 103 to avoid local vibration.

[0051] Furthermore, the aforementioned elastic component 103 includes a support rod 1031 and an elastic element 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 200. The elastic element 1032 is sandwiched between the buffer 200 and the bottom frame 102.

[0052] The aforementioned elastic element 1032 can be a metal steel spring. The support rod 1031 and the elastic element 1032 constitute an axial guiding constraint. The support rod 1031 restricts the elastic element 1032 to only compress or pop out in the axial direction. In complex vibration scenarios, the direction of vibration energy is uncertain. By guiding the elastic deformation direction of the elastic element 1032 through the support rod 1031, it can be ensured that the vibration energy is efficiently transmitted to the elastic element 1032 along the axial direction of the support rod 1031. Thus, the elastic element 1032 absorbs vibration energy and enhances the buffering effect of the elastic element 1032.

[0053] In this embodiment, the support rod 1031 has an installation end that penetrates the buffer member 200. A fixing member 1033 is connected to the installation end to prevent the buffer member 200 from detaching from the support rod 1031. 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, the fastener 1033 and the support rod 1031 can be connected by a threaded fit. To ensure that the position of the fastener 1033 on the support rod 1031 is not affected by vibration and shifts, the fastener 1033 uses a self-locking nut. The deeper the fastener 1033 is screwed into the support rod 1031, the greater the pre-compression of the elastic element 1032; the shallower the fastener 1033 is screwed into the support rod 1031, the smaller the pre-compression of the elastic element 1032.

[0055] By adjusting the pre-compression of the elastic element 1032, the overall stiffness coefficient and damping threshold of the vibration-resistant bracket can be adjusted. For example, in the high-frequency vibration section of the track and rail resonance, the pre-compression of the elastic element 1032 can be appropriately increased to keep the elastic element 1032 in the medium-high stiffness range, suppressing the transmission of small-amplitude high-frequency vibrations. In the low-frequency large-amplitude scenario of the bridge, the pre-compression can be appropriately reduced to release the flexible space of the elastic element 1032, making it easier for the elastic element 1032 to absorb large-amplitude impact energy.

[0056] In some embodiments, staff can directly adjust the pre-compression of the elastic element 1032 by rotating the fixing member 1033 without removing the optical cable junction box 400 or interrupting the optical fiber communication. This facilitates rapid on-site adjustment and maintenance. In addition, after a period of use, the elastic life of the elastic element 1032 decreases. During regular maintenance, staff can directly increase the pre-compression of the elastic element 1032 to ensure the normal elastic potential energy of the elastic element 1032, so that the elastic element 1032 is always in a stable and normal elastic expansion and contraction state. There is no need to replace the elastic element 1032 for a period of time. This design facilitates inspection and maintenance and can reduce maintenance costs.

[0057] In some embodiments, a distance scale is also provided on the support column, for example, with distances defined in 0.5mm increments. This distance scale extends from the area where the elastic element 1032 is located to the mounting end of the buffer 200. Workers can observe and determine the pre-compression of the spring through this distance scale, thereby facilitating the adjustment of the pre-compression of multiple elastic components 103 to ensure consistency. Of course, adjusting the pre-compression of the elastic components 103 by observing the distance scale is based on the premise that the material, size, and elastic parameters of the elastic element 1032 used in each elastic component 103 are consistent. This design ensures that the buffer 200 is always in a horizontal state, thereby guaranteeing the horizontal stability of the optical cable junction box 400.

[0058] In addition, after long-term service, the elastic element 1032 will undergo permanent deformation due to metal fatigue. During routine inspection and maintenance, staff can directly judge whether the elastic element 1032 is at risk of failure by observing the offset of the elastic element 1032 on the distance scale, so as to avoid the sudden breakage of the elastic element 1032 causing the optical cable junction box 400 to fall with the buffer 200.

[0059] like Figure 3 and Figure 4 As shown, the anti-vibration bracket for the optical cable splice box in this embodiment of the application has a limiting component 301 for clamping the optical cable on the mounting component 300. The limiting component 301 is used to limit the axial displacement of the optical cable extending from the optical cable splice box 400.

[0060] In the above embodiment, the support member 101 is provided with a sliding groove extending along the height direction, and a bolt is inserted through the mounting member 300. The bolt is confined within the sliding groove. By adjusting the tightness of the bolt within the sliding groove, the sliding or locking state of the mounting member 300 and the support member 101 can be adjusted accordingly, thus forming a sliding connection between the mounting member 300 and the support member 101. Of course, other sliding connection structures can also be used between the mounting member 300 and the support member 101; this embodiment is merely an example.

[0061] The mounting component 300 is exemplarily an "L"-shaped metal plate. Specifically, the limiting component 301 includes a first slot 3011 fixed on the mounting component 300 and a second slot 3012 detachably connected to the first slot 3011. The first slot 3011 and the second slot 3012 form a receiving cavity for the optical cable to pass through. The first slot 3011 and / or the second slot 3012 have a protruding limiting member 3013 on the side for abutting the optical cable. The limiting member 3013 prevents the optical cable from moving in the axial direction.

[0062] The receiving cavity enclosed by the first slot 3011 and the second slot 3012 is approximately elliptical. This design facilitates the adaptation of optical cables of different diameters and improves the versatility of the limiting component 301.

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

[0064] The flexible pad has a serrated protrusion 3015 on one side of the optical cable. Multiple protrusions 3016 are arranged at intervals on the serrated protrusion 3015. The serrated protrusion 3015 and the protrusions 3016 work together 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 the case of vibration, the axial slippage of the optical cable is counteracted by the engagement of the limiting member 3013 with the optical cable.

[0065] Furthermore, such as Figure 5 As shown, the first slot 3011 has a through hole 3014, and the limiting member 3013 has a protrusion for passing through the through hole 3014. The protrusion is embedded in the through hole 3014 so that the limiting member 3013 is engaged and fixed with the first slot 3011. This design can further improve the fixing effect between the limiting member 3013 and the first slot 3011, and prevent the limiting member 3013 from deviating from the first slot 3011 due to vibration.

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

[0067] It should be noted that in this embodiment of the application, a limiting member 3013 is fixedly engaged in both the first slot 3011 and the second slot 3012. The two limiting members 3013 together clamp the opposite sides of the optical cable and prevent the axial displacement of the optical cable.

[0068] With the above settings, the limiting component 301 on the vibration-damping bracket of the optical cable junction box directly bears the axial tension of the external optical cable, preventing the axial debris of the external optical cable from directly affecting the inside of the optical cable junction box 400 and affecting the vibration reduction effect.

[0069] Meanwhile, since the mounting component 300 is movably connected to the support component 101, and the limiting component 301 on the mounting component 300 fixes the optical cable extending from the optical cable junction box 400, when the external optical cable is subjected to environmental vibration, it first impacts the limiting component 301 on the mounting component 300. The impact energy is then absorbed and mitigated by the up-and-down movement of the mounting component 300, reducing the impact of the external optical cable on the internal structure of the optical cable junction box 400. Furthermore, the movable connection between the mounting component 300 and the support component 101 allows for easy adjustment of the actual height of the mounting component 300, facilitating compatibility with optical cable junction boxes 400 of different sizes and specifications. This eliminates the need for specially designed optical cable junction boxes 400 to fit different sizes and specifications, demonstrating strong versatility.

[0070] In some embodiments, such as Figure 2 As shown, each set of support members 101 is connected to a mounting member 300. Each set of support members 101 has two members spaced apart. The two 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, four support members 101 are fixed on the bottom frame 102. Each set of support members 101 is slidably connected to a mounting member 300. 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 swaying when the support member 101 is connected to the mounting member 300 on one side. On the two sets of support members 101 on opposite sides, a mounting member 300 is set on each side. The heights of the two mounting members 300 are not necessarily the same. This design also facilitates adaptation to various vibration scenarios, giving the cables extending from opposite sides of the optical cable junction box 400 a certain vibration redundancy and reducing the impact of the extending cables on the optical cable junction box 400.

[0072] It should be noted that, in this embodiment of the application, the mounting component 300 is detachably connected to the support component 101, the buffer component 200 is detachably connected to the optical cable junction box 400, the buffer component 200 is detachably connected to the bottom frame 102, and there is a receiving space 201 between the buffer component 200 and the bottom frame 102.

[0073] In the above embodiments, for example, the mounting component 300 and the support component 101 are connected by through bolts, the buffer component 200 and the optical cable junction box 400 are connected by bolts that pass through both, and the buffer component 200 and the bottom frame 102 are connected by an elastic component 103. Thus, the buffer component 200 is easier to disassemble and assemble.

[0074] Compared to related technologies that directly place the fiber optic splice box 400 on the channel, the design of the receiving space 201 utilizes the space originally occupied by the fiber optic splice box 400 to lay communication cables, power lines, etc., making full use of the installation space of the vibration-damping bracket. Furthermore, water accumulating at the bottom of the channel can be drained through the receiving space 201 of the vibration-damping bracket, preventing water accumulation in the channel from affecting the fiber optic splice box 400. Moreover, the design of the receiving space 201 creates an airflow channel under the vibration-damping bracket, accelerating heat dissipation from the fiber optic splice box 400.

[0075] This application also provides an optical cable connection device, including an optical cable splice box 400 and an anti-vibration bracket for the optical cable splice box connected to the optical cable splice box 400 in any of the above embodiments. Since the optical cable connection device includes the anti-vibration bracket for the optical cable splice box in any of the above embodiments, it possesses all the advantages of the anti-vibration bracket for the optical cable splice box.

[0076] like Figure 6 and Figure 7 As shown, in some embodiments, along the transmission direction of the optical cable, the optical cable splice box 400 is provided with at least two sets of fiber splicing tray assemblies at intervals. Each fiber splicing tray assembly includes multiple stacked fiber splicing trays 401, and the multiple fiber splicing trays 401 are connected by a common mounting shaft 404.

[0077] In the above embodiments, three fiber optic splice tray assemblies are generally provided. The three fiber optic splice tray assemblies can adopt the same structural design. Taking one fiber optic splice tray assembly as an example, each fiber optic splice tray assembly includes multiple stacked fiber optic splice trays 401. The multiple fiber optic splice trays 401 are fixed to the outer shell 402 of the optical cable splice box 400 by a common mounting shaft 404. The upper end of the mounting shaft 404 is fastened to the multiple fiber optic splice trays 401 by a nut thread engagement, avoiding gaps between the multiple fiber optic splice trays 401, thereby preventing vibration damage to the fiber optic splice trays 401.

[0078] In related technologies, multiple fiber optic tumblers 401 are generally connected by a side-mounted rotating shaft. Assembly and maintenance are performed by flipping the tumblers 401. However, this side-mounted rotating connection is susceptible to vibration, causing adjacent tumblers 401 to collide and potentially leading to connection failure. Therefore, by using a common mounting shaft 404 for multiple tumblers 401, the problem of tumblers 401 detaching due to vibration can be effectively avoided.

[0079] In some embodiments, a buffer pad is sandwiched between two adjacent fiber optic trolleys 401. The buffer pad may be a sponge pad or a silicone pad, etc., to further improve the shock resistance of the fiber optic trolley 401.

[0080] Furthermore, since multiple fiber fusion splice trays are provided in this embodiment, each fiber fusion splice tray can be installed with the optical cable of the corresponding operator. For example, the three fiber fusion splice trays can be installed with the optical cables of China Mobile, China Unicom and China Telecom respectively. The three operators are connected to each other in independent zones. During construction and maintenance, only the area where the target fiber fusion splice tray is located needs to be opened. It does not affect the normal transmission of optical fibers of other operators, does not interfere with each other, and does not involve cross-maintenance issues. This increases the optical fiber density in the optical cable junction box 400 and effectively improves the space utilization of the optical cable junction box 400.

[0081] It should be noted that there should be a certain gap between two adjacent fusion splice tray assemblies. This gap should be sufficient to block electromagnetic interference between optical fibers from different operators. For practical applications, this gap can be flexibly adjusted. Furthermore, different fusion splice tray assemblies can be equipped with operator-specific logos or colors. For example, a red fusion splice tray assembly corresponds to China Mobile, a blue fusion splice tray assembly to China Unicom, and a yellow fusion splice tray assembly to China Telecom, etc., which, in conjunction with QR code labels, allows for quick port location. This will not be elaborated further in this embodiment.

[0082] like Figure 7 As shown, in some embodiments, the optical cable junction box 400 includes an outer shell 402 and a support plate 403 disposed in the outer shell 402. The support plate 403 is used to support the fiber optic cable assembly, and the outer shell 402 and the support plate 403 are elastically connected.

[0083] The elastic connection between the support plate 403 and the outer shell 402 can be described with reference to the elastic component 103. For example, a connecting post 405 connects the support plate 403 and the outer shell 402, and a spring is sleeved on the connecting post 405, thus forming an elastic connection between the support plate 403 and the outer shell 402. Of course, multiple connecting posts 405 can be arranged at intervals along the circumference of the support plate 403, and the support plate 403 can be supported by the connecting posts 405 and the springs sleeved on the connecting posts 405.

[0084] The elastic connection between the support plate 403 and the outer shell 402 can reduce the vibration of the fiber fusion tray 401 on the support plate 403, thereby further improving the anti-vibration effect of the fiber fusion tray 401.
