[0036] Embodiment:

[0037] Please refer to Figure 1, the optical cable protection device of the present utility model is used to protect the jumper cable. The jumper cable includes a main cable 1, a fan-out sub-cable 4, and a splitter 2. The main cable 1 branches out at least one optical fiber and at least one strength member 5. The fan-out sub-cable 4 includes a plurality of branch sub-cables and connectors 3 connecting each branch sub-cable. Each branch sub-cable includes an optical fiber branched out from the main cable 1 and a protective sleeve surrounding the optical fiber. The splitter 2 fixes the main cable 1, the fan-out sub-cable 4, and the strength member 5 at the branching position of the main cable 1. The branching position has a first end towards one end of the main cable 1 and a second end towards one end of the fan-out sub-cable 4.

[0038] The optical cable protection device includes a main housing 7. The main housing 7 is used to accommodate the fan-out sub-cable 4 and the splitter 2, and one end of it is fixed on the main cable 1, and the other end is fixed on the free end of the strength member 5. All the strength members 5 pass through the main housing 7, and the free ends of the strength members 5 have handles.

[0039] More specifically, in a preferred embodiment, as Figure 1 shown in, a is used to represent the front end of the entire optical cable device, and b is used to represent the end of the entire optical cable device. Some main components behind the splitter 2, such as the fan-out sub-cable 4, the connector 3, etc., are preferably first integrally accommodated in the secondary housing 6. The secondary housing 6 is used to at least accommodate the connector 3 of the fan-out sub-cable 4. One end of the secondary housing 6 is sealed, and the other end is fixed on the splitter 2, the main cable 1, or the fan-out sub-cable 4.

[0040] In a preferred embodiment, the other end of the secondary housing may be provided with an opening 61, and the strength member passes through the main housing 7 through the opening 61. Of course, the other end of the secondary housing 6 can be fixed on the fan-out sub-cable 4. At this time, the secondary housing 6 may not be provided with an opening, and the strength member 5 directly passes through the inside of the main housing 7 to form a handle. As an alternative, the other end of the secondary housing 6 can also be fixed at the position of the main cable 1 or the first end of the splitter 2. At this time, the secondary housing 6 needs to be provided with an opening.

[0041] Then, the main housing 7 continues to be sleeved outside the secondary housing 6. The strength member 5 extending from the inside of the main cable 1 can pass through the opening 61 of the secondary housing 6 and then pass through the main housing 7, and is knotted at the end to form a handle.

[0042] In a preferred embodiment, the other end of the main housing is fixed at the connection between the main housing and the handle or the knot of the handle. In this way, both the main housing can be fixed and the connection point can be covered. For example, the front end of the main housing 7 can be fixed by a first fixing member 71 such as a cable tie, and the end of the main housing 7 can also be fixed by a third fixing member 51 such as a heat shrinkable tube. Thus, both the main housing can be sealed, and the knot of the strength member is blocked, making the entire protection device more complete and beautiful.

[0043] In addition, to further improve the protection effect, a protection tube 8 may also be sleeved on the main cable 1 for protecting the main cable, and a second fixing member 81 such as a cable tie is used for fixing. In this way, using the protection tube is beneficial to protecting the optical fiber in the main cable from being damaged and can also make the binding of the main cover body more firm.

[0044] Through the above design, on the one hand, the main components such as the fan-out sub-cable and the optical fiber protector in the main cover body and the optional secondary cover body can be fully protected, and the sub-cable will not be damaged by external forces during the laying project, or the pipe threading operation will not be hindered by being hooked. Specifically, that is, the main cover body can protect the secondary cover body and the fan-out sub-cable and is suitable for use in various complex environments, while the secondary cover body can protect the fan-out sub-cable, avoid dust, and facilitate disassembly and assembly to improve efficiency. On the other hand, by making full use of the handle formed by the strengthening rope passing through the end of the main cover body, the force is effectively prevented from being applied to the optical fiber connector or the branch area during the wiring pulling process, and the optical cable and the optical fiber connector connected to the optical cable are also protected from possible hooking or vibration.

[0045] In a preferred embodiment, the free end of the strengthening rope forms the handle by tying a knot, or an external handle is connected to the free end of the strengthening rope. In addition, the strengthening rope is formed by twisting, braiding or adhering multiple strands of strengthening yarns together. In this way, the pulling force can be made more concentrated, the pulling operation is convenient, and the yarn handle is more beautiful.

[0046] In another preferred embodiment, the secondary cover body is strip-shaped, and its inner diameter is basically equal to the maximum outer diameter of the fan-out sub-cable. In this way, the moving space of the connector can be restricted to avoid the sub-cable from being broken or damaged during movement. In addition, the secondary cover body can be made of flexible plastic, for example.

[0047] In another preferred embodiment, the main cover body is strip-shaped, and its inner diameter is basically equal to the maximum outer diameter of the secondary cover body. In this way, the smaller size of the main cover body is easier to pass through the wall or the installation pipe. In addition, the main cover body is a woven structure, for example.

[0048] In summary, the optical cable protection device according to the present invention can safely and reliably connect optical cables in various complex construction environments, effectively prevent the force from being applied to the optical fiber connector or the branch area during the wiring pulling process, and also protect the optical cable and the optical fiber connector from possible hooking or vibration. The protection device has a compact structure, is convenient for processing and on-site operation, and has cost-effectiveness, so it has good practical value and application prospects.

[0049] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
