Description

Technical Field

[0001] This utility model relates to optical fiber transmission connection devices, specifically to an optical fiber flange and an optical fiber splitter module. Background Technology

[0002] In optical module-related equipment, fiber optic flanges need to be installed on fiber optic discs to achieve functionality. Currently, there are two mainstream installation methods in existing technologies: one is to use double-sided adhesive bonding. Although this method is simple to operate, the double-sided adhesive is prone to failure and detachment after long-term use, which may cause serious problems such as the fiber optic flange separating from the fiber optic disc, fiber breakage, and optical module failure, affecting the normal use of the optical module; the other is to install using plastic molds. Although this method is more stable than bonding, the mold cost is higher, and the installation capacity of the fiber optic flanges in the molded products is limited, typically only two can be installed.

[0003] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an optical fiber flange and an optical fiber splitter module, aiming to solve the problem that the optical fiber flange is prone to detaching from the optical fiber disc in existing technologies.

[0005] The technical solution adopted by this utility model is as follows: an optical fiber flange, the optical fiber flange including a flange base plate, a limiting frame and a limiting plate; the flange base plate and the limiting plate are respectively fixed on both sides of the limiting frame, and there are two sets of limiting plates, which are respectively arranged at both ends of the limiting frame; the limiting frame is provided with a limiting groove adapted to the optical fiber flange, one end of the bottom of the optical fiber flange is located on the flange base plate, and the other end of the optical fiber flange is limited by the two sets of limiting plates.

[0006] According to the above scheme, anti-slip protrusions are provided on both sides above the limiting groove.

[0007] According to the above scheme, the anti-slip protrusion includes a first anti-slip protrusion and two second anti-slip protrusions, which are located on both sides of the limiting groove.

[0008] According to the above scheme, the flange base plate is provided with flange threaded holes.

[0009] According to the above scheme, the flange has four threaded holes, which are arranged in pairs on both sides of the flange base plate.

[0010] According to the above scheme, the limiting groove is a rectangular groove.

[0011] According to the above scheme, the flange base plate is rectangular.

[0012] According to the above scheme, the limiting plate is rectangular.

[0013] This utility model also discloses an optical fiber splitter module, including an optical fiber flange and an optical fiber flange plate as described above; there are multiple sets of optical fiber flanges, which are arranged in sequence and installed in the limiting groove of the optical fiber flange plate.

[0014] According to the above scheme, there are 8 sets of fiber optic flanges.

[0015] The beneficial effects of this utility model are as follows: 1. In this utility model, the fiber optic flange is designed with a limiting frame, and the fiber optic flange is limited within the limiting groove of the limiting frame; the fiber optic flange is fixed to the fiber optic disc, and the fiber optic flange and the fiber optic disc are connected through the fiber optic flange. Compared with the prior art, this utility model physically limits the fiber optic flange through the limiting groove of the limiting frame, which can resist the influence of environmental factors such as temperature fluctuations and slight vibrations, effectively prevent the fiber optic flange from detaching from the fiber optic disc, and avoid fiber breakage and optical module failure.

[0016] 2. The flexible design of the limiting frame and limiting groove in this utility model is not limited by the fixed structure of opening plastic molds.

[0026] A fiber optic flange 1 is mainly used for the integration and installation of a fiber optic flange 2; the fiber optic flange 1 includes a flange base plate 1-5, a limiting frame 1-1, and a limiting plate 1-6; The flange base plate 1-5 and the limiting plate 1-6 are respectively fixed on both sides of the limiting frame 1-1, and there are two sets of limiting plates 1-6, which are respectively located at both ends of the limiting frame 1-1; The limiting frame 1-1 has a limiting groove adapted to the optical fiber flange 2. The optical fiber flange 2 passes through the limiting groove, and the bottom of one end of the optical fiber flange 2 is located on the flange base plate 1-5.

[0027] In this utility model, the dimensions (such as width and depth) of the limiting groove need to be designed synchronously according to the interface type, installation quantity and preset layout of the fiber optic flange 2 in actual application.

[0028] In this utility model, the limiting plates 1-6 on both sides play a certain protective role for the fiber optic flange 2, avoiding damage to the fiber optic flange 2 caused by bumps during assembly.

[0029] Example 1 like Figure 1 As shown, this embodiment includes the fiber optic flange 1 as described above, and also includes: flange threaded holes 1-4 opened on the flange base plate 1-5, for connecting to the fiber optic disc 3 described below by bolts or screws.

[0030] In this embodiment, anti-slip protrusions are provided on both sides above the limiting groove. The fiber optic flange 2 is installed in the limiting groove. After the flange base plate 1-5 is installed on the fiber optic disc 3, the binding strap 4 connects the fiber optic flange 1 and the fiber optic disc 3 into a whole for the next installation. The binding strap 4 is fixed by the anti-slip protrusions above. The two sides of the binding strap 4 will form a mechanical engagement with the anti-slip protrusions, increasing the friction of the binding strap 4.

[0031] In this embodiment, the anti-slip protrusion includes a first anti-slip protrusion 1-2 and two second anti-slip protrusions 1-3, with the first anti-slip protrusion 1-2 and the second anti-slip protrusions 1-3 located on both sides of the limiting groove.

[0032] In this embodiment, the limiting groove is a rectangular groove; both the flange base plate 1-5 and the limiting plate 1-6 are rectangular.

[0033] In this embodiment, there are four threaded holes 1-4 on the flange, which are arranged in pairs on both sides of the flange base plate 1-5. Example 2 like Figure 2 The fiber optic splitter module shown includes a fiber optic flange 2 and a fiber optic flange 1 as described in Embodiment 1. The fiber optic flange 2 has multiple sets, which are arranged in sequence and installed in the limiting groove of the fiber optic flange 1, and are fixed by binding straps. The bottom of the fiber optic flange 1 is fixedly connected to the fiber optic disc 3.

[0034] In this embodiment, the top of the fiber optic flange 2 is provided with a limiting protrusion 2-1 and a spring piece 2-2. When installing the fiber optic flange 2, the spring piece 2-2 on the top is pressed down so that it passes through the limiting groove together. After being released, the limiting protrusion 2-1 and the spring piece 2-2 of the fiber optic flange 2 are located on both sides of the limiting frame 1-1, respectively. The fiber optic flange 2 can be limited and fixed in the limiting groove through the cooperation of the limiting protrusion 2-1 and the spring piece 2-2. The fiber optic flange 2 is an existing structure and will not be described in detail here.

[0035] In this embodiment, there are 8 sets of fiber optic flanges 2. In this embodiment, the fiber optic flange 2 is installed in the limiting groove. After the flange base plate 1-5 is installed on the fiber optic disc 3, the two are fixed together by the binding strap 4 before subsequent installation.

[0036] In this embodiment, to achieve a stable connection between the fiber optic splitter module and the fiber optic disc 3 and facilitate subsequent maintenance, the fiber optic splitter module is fixedly mounted on the fiber optic disc 3. Specifically, the flange base plate 1-5 of the fiber optic flange 1 is provided with flange threaded holes 1-4, and the corresponding installation area of ​​the fiber optic disc 3 has multiple matching mounting holes of appropriate size. The two are detachably connected by bolts passing through the corresponding holes in sequence, which ensures that the fiber optic flange 1 does not shift during equipment operation and facilitates disassembly, replacement, or adjustment according to maintenance needs.

[0037] The specific process of assembling and installing the fiber optic disk 3 in this embodiment is as follows: 1. Confirm that the model and quantity of the fiber optic flange 2 to be installed are compatible with the size of the limiting groove of the fiber optic flange 1. 2. Align the fiber optic flanges 2 one by one with the corresponding limiting slots on the limiting frame 1-1. After pressing down the spring piece 2-2, slowly insert it along the slot direction until the spring piece 2-2 passes through the limiting slot of the limiting frame 1-1 and pops out. At this time, the limiting protrusion 2-1 of the fiber optic flange 2 and the spring piece 2-2 are located on both sides of the limiting frame 1-1, and the two work together to limit the fiber optic flange 2 in the limiting slot. At this time, one end of the fiber optic flange 2 is supported on the flange base plate 1-5.

[0038] 3. After completing the installation of fiber optic flange 2, fiber optic flange 1 forms a fiber optic splitter module. Align it with the preset installation position of fiber optic disc 3, so that the flange thread holes 1-4 on the flange base plate 1-5 are aligned with the corresponding installation holes on the fiber optic disc 3. Use bolts or screws to pass through the flange thread holes 1-4 and the installation holes of the fiber optic disc 3, and tighten them to the preset torque to achieve a stable connection between fiber optic flange 1 and fiber optic disc 3, thus completing the overall installation of fiber optic flange 2.

[0039] After the fiber optic flange 1 and the fiber optic disc 3 are bolted together, they are further fixed together with the strap 4 to form a whole for subsequent installation. The two sides of the strap 4 engage with the first anti-slip protrusion 1-2 and the second anti-slip protrusion 1-3 on both sides above the limiting groove. The anti-slip protrusions increase the friction between the strap 4 and the limiting frame 1-1 to prevent the strap 4 from sliding axially.

[0040] Other contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
