Description

Technical Field

[0001] This utility model relates to the field of optical cable joint protection technology, specifically to a visual indoor optical cable joint termination connection protection tube. Background Technology

[0002] In today's era, existing indoor optical cable termination connections mainly employ optical cable terminal boxes, optical cable splice boxes, termination reels, and protective sleeve fusion splicing. However, these connection methods generally suffer from poor adaptability. In some scenarios, the terminal boxes are too bulky to fit due to limited space; fiber optic splices break under high-frequency vibrations; and the lack of waterproof and dustproof seals leads to signal attenuation, fiber breakage, and component corrosion, ultimately causing communication failures and increasing maintenance costs. Therefore, there is an urgent need for a compact, waterproof, and dustproof optical cable termination connection device that can stably connect fiber optic splices to solve the core problems of poor adaptability of existing terminal boxes and signal attenuation caused by the lack of shock absorption, waterproof, and dustproof seals in current technologies. Utility Model Content

[0003] The purpose of this utility model is to provide a compact, waterproof and dustproof optical cable connector termination device that can stabilize optical fiber splicing points, aiming to solve the problem of poor adaptability of existing terminal boxes and lack of shock absorption, waterproof and dustproof sealing considerations, which leads to signal attenuation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A visual indoor optical cable connector end-connection protection tube includes a transparent tube body open at both ends. Waterproof connectors are detachably connected to both ends of the transparent tube body. A waterproof cap is detachably connected to the end of each waterproof connector. One end of the waterproof connector connected to the waterproof cap has a tension section for the optical cable to pass through. The outer wall of the tension section is conical. The waterproof cap has a compression through-hole that mates with the tension section. The diameter of the compression through-hole is larger than the end face diameter of the tension section. The tension section includes several elastic ribs arranged in a spaced-around pattern, forming an installation through-hole for the optical cable to pass through. An elastic gasket is sandwiched between two adjacent elastic ribs.

[0005] Preferably, the inner wall of the mounting through hole is tapered, and the outer port diameter of the mounting through hole is larger than the inner port diameter.

[0006] Preferably, the transparent tube is threadedly connected to the waterproof connector; the waterproof connector is threadedly connected to the waterproof cap.

[0007] Preferably, the outer edge of the waterproof cap is a regular hexagon.

[0008] Preferably, the transparent tube is made of acrylic material.

[0009] Preferably, the transparent tube is filled with transparent optical fiber oil.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) The present application has a visual indoor optical cable connector termination connection protection tube. The tube is small and can adapt to various application scenarios. The waterproof connector can effectively fix the optical fiber and provide waterproof and dustproof sealing protection for the optical cable connector termination connection. It effectively solves the problems of signal attenuation, optical fiber breakage and component corrosion caused by contact with external water and dust.

[0011] (2) The present application visualizes the indoor optical cable connector termination connection protection tube, and sets the inner wall of the installation through hole as conical. The large diameter of the outer port makes it easier for the optical fiber to pass through. When the optical fiber passes through the installation through hole, the elastic rib of the tensioning part is tightened by the waterproof cap, so that the conical slope of the inner wall of the installation through hole is finally parallel to the optical fiber that has passed through, realizing a tight fit with the optical fiber that has passed through, effectively enhancing the tightness of the fit between the tensioning part and the optical fiber to enhance the waterproofness of the protection tube. At the same time, an elastic gasket is sandwiched between two adjacent elastic ribs to form a double waterproof guarantee, further enhancing the waterproof effect of the protection tube.

[0012] (3) The present application has a visual indoor optical cable connector termination connection protection tube. The transparent tube body is made of acrylic material, which makes the tube body more rigid and less likely to break due to collision or vibration, and the safety during use is higher. Injecting transparent optical cable oil into the transparent tube body can reduce the reflection and scattering loss of light at the interface between the tube body and the air, and between the fiber core and the tube body, making the optical signal transmission more stable and efficient. Moreover, its transparent characteristics will not block the observation line of the tube body, and will not affect the real-time monitoring of the internal status, thus taking into account both the protection function and the visualization requirements.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example like Figure 1-4 As shown, this is the first embodiment of the present invention. A visual indoor optical cable connector end-connection protection tube includes a transparent tube 1 with two openings and a diameter of M20. Waterproof connectors 2 are detachably connected to both ends of the transparent tube 1. M16 internal threads are machined on both ends of the transparent tube 1 for threaded connection with the M16 external thread waterproof connectors 2. A waterproof cap 3 is detachably connected to the end of the waterproof connector 2. The end of the waterproof connector 2 connected to the waterproof cap 3 is provided with a tensioning part for the optical cable to pass through. The outer wall of the opening portion is conical. The waterproof cap 3 has a compression through hole 4 that matches the opening portion. The diameter of the compression through hole 4 is larger than the end face diameter of the opening portion. The opening portion includes several elastic ribs 5 arranged in a spaced-around pattern. The several elastic ribs 5 form an installation through hole 6 for the optical cable to pass through. An elastic gasket 7 is sandwiched between two adjacent elastic ribs 5. The waterproof cap 3 has a through hole that matches the opening portion. Preferably, the waterproof connector 2 is threadedly connected to the waterproof cap 3. In use, this invention features a waterproof connector 2 at one end of the optical cable. The mounting through-hole 6 on the hinged part has a large diameter tapered outer port, facilitating the passage of the optical fiber. When the optical fiber passes through the mounting through-hole 6, the elastic ribs 5 of the hinged part are tightened by the waterproof cap 3, making the tapered slope of the inner wall of the mounting through-hole 6 parallel to the passed optical fiber, achieving a tight fit with the passed optical fiber. This effectively enhances the tightness of the fit between the hinged part and the optical fiber, thereby enhancing the waterproofness of the protective tube. At the same time, an elastic gasket 7 is sandwiched between two adjacent elastic ribs 5, forming a double waterproof guarantee, further strengthening the waterproof effect of the protective tube. Afterward, the optical fiber at the tube body is heat-fused to the optical fiber at the other end and then inserted into the protective tube. Transparent optical cable oil is injected into the tube body, causing the threaded connection between the waterproof connector 2 and the waterproof cap 3 at the other end to gradually tighten to a tight fit. This allows the ribs to squeeze against each other, achieving a seal of the tube body and fixing of the optical fiber. This solves the core problems of poor adaptability and lack of shock absorption, waterproofing, dustproofing, and sealing considerations in existing optical cable connector termination devices, which lead to signal attenuation.

[0017] In this embodiment, the waterproof and dustproof seal of the optical cable connector termination device is achieved through the cooperation of the transparent tube 1, the waterproof connector 2, and the waterproof cap 3, which effectively avoids the core problems of poor adaptability and lack of shock absorption, waterproof and dustproof sealing considerations in the original optical cable connector termination device, which leads to signal attenuation.

[0018] As a preferred embodiment of this example, the transparent tube 1 is made of acrylic material, which makes the tube more rigid and less prone to breakage due to collision or vibration, thus ensuring higher safety during use.

[0019] As a preferred embodiment of this example, the transparent optical cable oil uses Yangtze Optical Fibre and Cable (YOFC) LARMOR® YIL000, which reduces the reflection and scattering loss of light at the interface between the tube and the air, and between the fiber core and the tube, making the transmission of optical signals more stable and efficient. Moreover, its transparency will not obstruct the view inside the tube and will not affect the real-time monitoring of the internal status, thus taking into account both protection and visualization requirements. In a preferred embodiment of this example, the elastic gasket 7 is made of silicone rubber or EPDM rubber.

[0020] In other embodiments of this utility model, the waterproof cap 3 at any end of the first embodiment is replaced with a transparent tube 1. The corresponding end of the transparent tube 1 is machined with an internal thread for engaging with the external thread at one end of the opening portion of the waterproof connector 2 to achieve threaded connection and sealing assembly. This achieves the extension of the protective tube to connect the external thread at one end of the opening portion of the waterproof connector 2 with the internal thread of the transparent tube 1.

[0021] In this embodiment, the waterproof cap 3 is flexibly replaced with a transparent tube 1 with internal threads, which precisely matches the external threads of the waterproof connector 2 to achieve a sealed connection. While ensuring waterproof sealing, the protective tube can be lengthened and extended according to actual needs. This not only retains the reliability of the original structure, but also improves the product's adaptability and ease of use in different scenarios.

[0022] In other embodiments of this utility model, a series of transparent tubes 1 (such as M16, M20, M25 diameter tubes) are designed, and waterproof connectors 2 of different sizes are matched (with reducing threads, such as M20 to M16).

[0023] It is compatible with different specifications of optical cables such as single-mode and multi-mode, and meets diverse joint protection needs through modular combination, reducing the types of spare parts and improving versatility.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
