[0031] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Embodiment 1

[0033] As Figures 1-4 shown, the present invention relates to an optical fiber disk optical fiber splice closure, which includes an extended optical fiber disk 1, a clamping member 2, a transfer hinge 3, and an extended optical fiber disk extension support 4. The present invention aims to solve the technical limitation that the assembly position of the traditional optical fiber splice closure is fixed, and through an innovative modular design, flexible positioning and precise adjustment of heat shrinkable sleeves or optical device PLCs are achieved.

[0034] As Figures 1-4As shown in the figure, the extended fiber optic disc 1 of the present invention is one of the core components of the present invention, and its design embodies the technical characteristics of precise guidance and flexible connection. A first guiding hole 1.1 extending along the X-axis direction is provided in the middle of this component. The main function of the first guiding hole 1.1 is to realize the sliding guidance of the clamping member 2 in the X-axis direction. On both sides of the first guiding hole 1.1, a plurality of clamping member connection hole groups arranged at intervals along the X-axis direction are evenly provided. Each clamping member connection hole group is composed of two key elements: a second guiding hole 1.2 arranged in one-to-one correspondence with the guiding slide 2.3, and a clamping member fixing hole 1.3 arranged in correspondence with the connecting boss 2.4. The second guiding hole 1.2 extends along the Y-axis direction and communicates with the first guiding hole 1.1, while the clamping member fixing hole 1.3 is located between the two second guiding holes 1.2 and does not communicate with the first guiding hole 1.1. This carefully designed structure enables the second guiding hole 1.2 to realize the sliding guidance of the clamping member 2 in the Y-axis direction, and at the same time limits the smooth embedding of the connecting boss 2.4 in the X-axis direction into the clamping member fixing hole 1.3.

[0035] As Figures 5-6 As shown in the figure, the clamping member 2 of the present invention includes a substrate 2.1. On one side end face of the substrate 2.1, a plurality of clamping pieces 2.2 arranged in parallel and at intervals along the X-axis direction are provided. On the other side end face, 2 guiding slides 2.3 and 1 connecting boss 2.4 are symmetrically arranged. Each clamping piece 2.2 is composed of a vertical plate portion 2.2.1 arranged perpendicular to the substrate 2.1. On both sides of the vertical plate portion 2.2.1, mirror-symmetrical retaining pieces 2.2.2 are provided, and an obtuse angle is designed between the two. Rubber clamping bosses 2.2.3 are provided on the side end faces of the retaining pieces 2.2.2, and clamping bosses 2.2.4 arranged at intervals along the Z-axis direction are also provided on at least one side end face of the vertical plate portion 2.2.1. These carefully designed details not only enhance the fixing ability of the clamping piece 2.2, but also provide good shock absorption and anti-slip performance. It should be noted that the clamping piece 2.2 is made of an elastically deformable material, further improving its adaptability and flexibility.

[0036] The retaining plate 2.2 of the present invention is normally tilted downward. When a heat shrink tubing or PLC device is inserted, the baffle is stretched open, and the elastic deformation of the baffle holds the heat shrink tubing or device in place, preventing it from easily falling out. The rubber retaining boss 2.2.3 of the present invention increases friction, securing the heat shrink tubing or device more securely. The retaining boss 2.2.4 of the present invention prevents the heat shrink tubing or device from easily popping out of the slot. Compared to conventional slots currently used on the market, this slot has a more rational structural design and more available internal space, allowing the holder to accommodate more heat shrink tubing (conventional equivalent slots currently hold two heat shrink tubing per slot, for a total of six slots, for a total of 12 heat shrink tubing; this new holder holds three heat shrink tubing per slot, for a total of six slots, for a total of 18 heat shrink tubing). This increases the disc's load-bearing capacity and enhances the product's market potential. At the same time, compared with conventional discs, the first guide hole 1.1 of the present invention facilitates the installation of the clamping member, and the clamping member can be more easily placed in the guide rail groove, which facilitates the installation of the clamping member; the two rows of second guide holes 1.2 involved in the present invention can guide the clamping member into the clamping slot, so as to meet the installation requirements of the clamping member from two directions and adapt to different product installation requirements; the disc of the present invention can be more compact in use, and the heat shrink tubing clamping member can be adapted to different positions according to the actual product situation, making the application of the disc more flexible.

[0037] like Figures 7-9 As shown, the design of the transfer hinge 3 and the extended fiber optic disc extension bracket 4 of the present invention further expands the functionality of the fiber optic splice box. The extended fiber optic disc extension bracket 4 is composed of a base plate 4-1 and a support plate 4-2 arranged at an angle thereto. The support plate 4-2 is provided with a plurality of hinge mounting grooves 4-3 equidistantly spaced along its inclination direction, and a limit baffle 4-4 is also provided at one end of each hinge mounting groove 4-3. This design not only enhances the stability of the structure, but also provides a precise positioning mechanism for the subsequent installation of the fiber optic disc bracket 5. The fiber optic disc bracket 5 includes a support portion and two bosses 5.1 spaced apart along the X-axis direction. Its design precisely matches the size and spacing of the hinge mounting groove 4-3, ensuring the accuracy and reliability of the installation.

[0038] Through the innovative combination of the extended fiber optic disc 1, the clamping member 2, the transfer hinge 3, and the extended fiber optic disc extension bracket 4, the present invention realizes the flexible adjustment of the assembly position of the fiber optic splice case. Whether it is a heat shrinkable sleeve or an optical device PLC, precise positioning can be achieved through a precise guiding mechanism and a clamping structure. This modular and adjustable design concept not only meets the requirements of diverse application scenarios such as communication, network systems, and cable television, but also provides higher flexibility and reliability for the key connection devices in the fiber optic communication network. Compared with traditional fixed fiber optic splice cases, the present invention has significant advantages in terms of versatility, flexibility, and adaptability, providing important technical support for the refined and intelligent construction of fiber optic communication infrastructure.

[0039] Embodiment 2

[0040] In this embodiment, the structure of the clamping member 2 of the fiber optic disc fiber optic splice case has been systematically innovated. The clamping piece 2.2 is made of a high-performance polyetheretherketone (PEEK) composite material, and its composite ratio is 85% PEEK resin and 15% glass fiber, significantly improving the mechanical strength and temperature resistance of the material. The thickness of the vertical plate part 2.2.1 is designed to be 2.5 mm, ensuring sufficient structural strength while maintaining light weight. To enhance multi-scenario adaptability, a trapezoidal microgroove structure is designed on the side of the vertical plate part 2.2.1. Each microgroove is 0.3 mm deep, 0.2 mm wide, and spaced 0.5 mm apart. This microscopic structure can provide better dimensional stability in different temperature and humidity environments.

[0041] The rubber clamping boss 2.2.3 adopts a porous microfoamed silica gel process, and its surface microstructure presents a dandelion fluff shape, with pore diameters between 10 - 30 microns. This special structure not only increases the surface contact area but also significantly improves the grasping ability for optical cables and optical devices. By adding a hydrophilic nano-coating on the surface of the clamping boss 2.2.3, the adaptability to optical cables of different materials is further enhanced. The hardness of each clamping boss 2.2.3 is controlled at 45 ± 5 degrees Shore A, and it can adapt to temperature changes from -40°C to 85°C.

[0042] The design of the guiding slide 2.3 adopts a precision machining process, and its surface roughness is controlled below Ra0.4 microns. A self-lubricating titanium alloy coating is added to the slide surface, reducing the friction coefficient to below 0.08, ensuring the smooth sliding of the clamping member 2 in the X-axis and Y-axis directions. The inner wall of the second guiding hole 1.2 adopts a plasma spraying process, adding a ceramic zirconia wear-resistant coating, extending the service life of the guiding hole to more than 100,000 sliding cycles.

[0043] Embodiment 3

[0044] The extended optical fiber disk extension bracket 4 of this embodiment is integrally die-cast from aerospace-grade 7075 aluminum alloy, with a tensile strength reaching 572 MPa and a yield strength exceeding 503 MPa. The thickness of the bottom plate 4-1 is 4 mm, and the thickness of the support plate 4-2 is 3.5 mm. It adopts an internal honeycomb reinforcement structure, significantly improving the overall rigidity while maintaining light weight.

[0045] The innovative design of the hinge installation groove 4-3 lies in its built-in multi-stage damping buffer system. Each installation groove is 25 mm long, 10 mm wide, and 6 mm deep, with three layers of micro spring buffer units embedded inside. The first layer is a high-elastic polyurethane buffer pad with a thickness of 0.5 mm; the middle layer is a nitinol micro spring with a wire diameter of 0.2 mm; the outermost layer is a silicone buffer pad with a thickness of 0.3 mm. This multi-layer buffer design can effectively absorb vibration energy in the frequency range of 20 - 2000 Hz, with an attenuation rate as high as 85%.

[0046] The limit baffle 4-4 is made of a high molecular composite material, with a honeycomb microporous structure designed inside, the pore diameter is 0.1 - 0.3 mm, and the porosity is 65%. This structure not only significantly reduces the weight of the baffle but also effectively attenuates the vibration frequency, and the vibration attenuation coefficient can reach 0.2. The transfer hinge 3 is made of imported S32750 duplex stainless steel material, with a yield strength of 550 MPa and excellent corrosion resistance, and it can remain unchanged for 1000 hours in a salt spray corrosion experiment.

[0047] The surface of the connection boss of the optical fiber disk bracket 5 is coated with a plasma-sprayed ceramic coating with a thickness of 0.08 mm, which is composed of composite materials such as zirconia and alumina. The coating hardness can reach HV1200, significantly improving the wear resistance, and the friction coefficient is as low as 0.1. The surface of the connection boss is designed with micron-level anti-slip textures, with a texture depth of 0.05 mm and a spacing of 0.2 mm, further enhancing the connection stability.

[0048] These two extended embodiments comprehensively improve the performance and reliability of the optical fiber splice closure through multi-dimensional innovations in materials, structures, processes, etc., providing more refined and reliable technical solutions for different application scenarios.
