Detailed implementation manners

[0020] 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.

[0021] Embodiment 1 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. Through an innovative modular design, flexible positioning and precise adjustment of heat shrinkable sleeves or optical device PLCs are realized.

[0022] As Figures 1-4 shown, the extended optical fiber disk 1 of the present invention is one of the core components of the present invention, and its design reflects the technical characteristics of precise guidance and flexible connection. A first guiding hole 1.1 extending along the X axis 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. On both sides of the first guiding hole 1.1, a plurality of clamping member connection hole groups are evenly arranged at intervals along the X axis. 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 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, and at the same time limits the connecting boss 2.4 to smoothly embed into the clamping member fixing hole 1.3 in the X axis.

[0023] As Figures 5-6As shown, the clamping member 2 of the present invention includes a base plate 2.1, and a plurality of clamping plates 2.2 arranged in parallel and spaced relation along the X-axis are arranged on one end face of the base plate 2.1, and two guide slides 2.3 and a connecting boss 2.4 are symmetrically arranged on the other end face. Each clamping plate 2.2 is composed of a vertical plate portion 2.2.1 arranged perpendicular to the base plate 2.1, and mirror-symmetrical baffles 2.2.2 are arranged on both sides of the vertical plate portion 2.2.1, and an obtuse angle is formed between the two. A rubber clamping boss 2.2.3 is arranged on the side end face of the baffle 2.2.2, and a clamping boss 2.2.4 arranged in spaced relation along the Z-axis is also arranged on at least one end face of the vertical plate portion 2.2.1. These carefully designed details not only enhance the fixing ability of the clamping plate 2.2, but also provide good shock absorption and anti-slip performance. It is worth noting that the clamping plate 2.2 is made of an elastically deformable material, which further enhances its adaptability and flexibility.

[0024] The holding piece 2.2 of the present invention is in a downward tilted state in a normal state. When a heat shrink tube or a PLC device is loaded, the baffle will be stretched open, and the heat shrink tube or the device will be held by the elastic deformation of the baffle, and it will not fall off easily. The rubber holding boss 2.2.3 of the present invention can increase the friction force, so that the heat shrink tube or the device is held more firmly. The holding boss 2.2.4 of the present invention can limit the heat shrink tube or the device from popping out of the slot easily. Compared with the conventional slot currently used on the market, the structural design of the slot is more reasonable, and there are more internal spaces available, so that the holder can bear more heat shrink tubes (the conventional equivalent slot currently has one slot that can carry 2 heat shrink tubes, and a total of 6 slots can carry 12 heat shrink tubes; the new holder has one slot that can carry 3 heat shrink tubes, and a total of 6 slots can carry 18 heat shrink tubes), so that the disk has a greater carrying capacity and the product has more 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 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 at the same time, the heat shrink tube clamping member can be adapted to different positions according to the actual product situation, making the application of the disc more flexible.

[0025] like Figures 7-9As shown in the figure, the design of the adapter hinge 3 and the extended optical fiber disk extension bracket 4 of the present invention further expands the functionality of the optical fiber splice enclosure. The extended optical fiber disk extension bracket 4 consists of a bottom plate 4-1 and a support plate 4-2 arranged at an angle thereto. A plurality of hinge mounting grooves 4-3 are equidistantly spaced along the inclined direction of the support plate 4-2, and a limiting baffle 4-4 is provided at one end of each hinge mounting groove 4-3. This design not only enhances the structural stability but also provides an accurate positioning mechanism for the subsequent installation of the optical fiber disk bracket 5. The optical fiber disk bracket 5 includes a support portion and two bosses 5.1 spaced along the X-axis, and its design is precisely matched with the size and spacing of the hinge mounting grooves 4-3, ensuring the accuracy and reliability of the installation.

[0026] Through the innovative combination of the extended optical fiber disk 1, the clamping member 2, the adapter hinge 3, and the extended optical fiber disk extension bracket 4, the present invention realizes the flexible adjustment of the assembly position of the optical fiber splice enclosure. 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 key connection devices in the optical fiber communication network. Compared with traditional fixed optical fiber splice enclosures, the present invention has significant advantages in terms of versatility, flexibility, and adaptability, providing important technical support for the refined and intelligent construction of optical fiber communication infrastructure.

[0027] Embodiment 2 In this embodiment, the structure of the clamping member 2 of the optical fiber disk optical fiber splice enclosure has been systematically innovated. The clamping piece 2.2 is made of a high-performance polyetheretherketone (PEEK) composite material with a composite ratio of 85% PEEK resin and 15% glass fiber, significantly improving the mechanical strength and temperature resistance of the material. The thickness of the vertical plate portion 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 portion 2.2.1, with each microgroove having a depth of 0.3 mm, a width of 0.2 mm, and a spacing of 0.5 mm. This microscopic structure can provide better dimensional stability in different temperature and humidity environments.

[0028] 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 of the optical cable 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.

[0029] The guiding slide table 2.3 is designed with precision machining technology, and its surface roughness is controlled below Ra0.4 micrometers. A self-lubricating titanium alloy coating is added to the slide table surface, reducing the friction coefficient to below 0.08 to ensure the smooth sliding of the clamping part 2 in the X-axis and Y-axis directions. The inner wall of the second guiding hole 1.2 adopts plasma spraying technology, and a ceramic zirconia wear-resistant coating is added, extending the service life of the guiding hole to more than 100,000 sliding cycles.

[0030] Example 3 The extended optical fiber disc 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 strengthening structure, significantly improving the overall rigidity while maintaining light weight.

[0031] The innovative design of the hinge mounting groove 4-3 lies in its built-in multi-stage damping buffer system. Each mounting 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, 0.5 mm thick; the middle layer is a nitinol micro spring with a wire diameter of 0.2 mm; the outermost layer is a silicone buffer pad, 0.3 mm thick. 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%.

[0032] The limit baffle 4-4 is made of a polymer composite material, with a honeycomb microporous structure designed inside, with a pore diameter of 0.1 - 0.3 mm and a porosity of 65%. This structure not only significantly reduces the weight of the baffle but also effectively attenuates the vibration frequency, with a vibration attenuation coefficient of up to 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 test.

[0033] The surface of the connecting boss of the optical fiber disc 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 with a friction coefficient as low as 0.1. The surface of the connecting 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.

[0034] These two extended embodiments comprehensively improve the performance and reliability of the optical fiber splice case through multi-dimensional innovations in materials, structures, processes, etc., providing more refined and reliable technical solutions for different application scenarios.
