Description

Technical Field

[0001] This utility model relates to the field of optical cable technology, and in particular to a double-protected distribution optical cable. Background Technology

[0002] Double-sheathed distribution optical cable is an optical cable with a double-layer protection structure. The inner sheath is close to the optical fiber to provide basic protection, while the outer sheath and reinforcing elements provide additional mechanical strength and environmental adaptability, enabling it to maintain excellent durability and reliability in a variety of harsh environments. It is suitable for various occasions such as indoor and outdoor communication networks.

[0003] Double-protected optical fiber cables are typically installed in outdoor overhead, underground pipeline, direct burial, or underwater environments, as well as indoor environments such as data centers and office buildings. They are used to lay long-distance communication lines and connect network equipment between or within buildings. Their installation locations are diverse, aiming to provide a stable and reliable communication network.

[0004] However, the following problems were found in the implementation of the relevant technology: In general, most buildings inevitably have animals such as insects and rodents, and the material of the outer sheath of the optical cable has a certain attraction to these animals, or the optical cable destroys their habitat during the installation process. This causes them to attack the optical cable in order to find food or nesting materials, resulting in damage to the optical cable. In view of this, a double-sheathed distribution optical cable is provided to overcome the above defects. Utility Model Content

A round hole is provided on one side of the locking block, and the round hole on one side of the locking block is located on one side of the fixing hole.

A filling layer 8 is in contact with the surface of the optical fiber body 9. The filling layer 8 is located inside the inner sheath 7, and its outer side is in contact with the inner side of the inner sheath 7. The inner sheath 7 is located inside the reinforcing layer 6, and its outer side is in contact with the inner side of the reinforcing layer 6. The reinforcing layer 6 is located inside the outer sheath 5, and its outer side is in contact with the inner side of the outer sheath 5. An elastic sleeve 1 is in contact with the surface of the outer sheath 5, and the inner side of the elastic sleeve 1 has an opening. The device includes a fixing groove 10, an inner side of an elastic sleeve 1 containing a reagent sac 4, a connecting block 2 glued to one side of the elastic sleeve 1, a locking block 3 glued to one side of the elastic sleeve 1, and a fixing block 12 on one side of the elastic sleeve 1. In this invention, the reagent sac 4 is fixed in place by the elastic sleeve 1, and then the elastic sleeve 1 is fixed to the surface of the outer sheath 5. In this way, when insects and rodents gnaw on the optical cable, they will first gnaw on the reagent sac 4, and when the reagent sac 4 breaks, the reagent inside the reagent sac 4 will leak out, thereby driving away the surrounding insects and rodents and preventing them from gnawing on the optical cable again and damaging it.

[0023] As a further implementation of the above technical solution: the bottom end of the connecting block 2 is fixedly connected to the top end of the fixing block 12, and the inner side of the card block 3 is provided with a card groove 11. The fixing block 12 is slidably connected to the card groove 11. By setting the fixing block 12, it is convenient to fix the elastic sleeve 1 on the outer sheath 5 by sliding between the fixing block 12 and the card block 3.

[0024] As a further implementation of the above technical solution: a fixing hole 13 is provided on one side of the fixing block 12, and a threaded groove is provided on the inner side of the fixing hole 13. A round hole is provided on one side of the locking block 3. The round hole on one side of the locking block 3 is located on one side of the fixing hole 13. By setting the locking block 3, it is convenient to accommodate the fixing block 12 through the locking block 3.

[0025] As a further implementation of the above technical solution: the length of the reagent bag 4 is consistent with the length of the fixing groove 10, the reagent bag 4 is engaged with the fixing groove 10, and the inside of the reagent bag 4 is filled with repellent reagent. By setting the reagent bag 4, it is convenient to contain the reagent for repelling insects and rodents.

[0026] As a further implementation of the above technical solution: the vertical cross section of the slot 11 is consistent with the vertical cross section of the fixing block 12, and the number of the slot 3 fixedly connected by the connecting block 2 is two. The slot 11 is opened at the top of the slot 3. By setting the connecting block 2, it is convenient to fix the fixing block 12 through the block.

[0027] As a further implementation of the above technical solution: the bottom end of the connecting block 2 contacts the top end of the card block 3, the outer sheath 5 is made of polyethylene, and the inner sheath 7 is also made of polyethylene. By setting the outer sheath 5, it is convenient to protect the optical cable through the outer sheath 5.

[0028] As a further implementation of the above technical solution: a reinforcing element is added to the inner side of the outer sheath 5. The reinforcing element added to the inner side of the outer sheath 5 is aramid fiber. Aramid fiber is also added to the inner side of the inner sheath 7. By adding aramid fiber to the inner side of the outer sheath 5, the strength of the outer sheath 5 can be improved by adding aramid fiber.

[0029] Working principle:

[0030] When using this invention, the user should first install the reagent bag 4 manually or mechanically into the fixing groove 10 inside the elastic sleeve 1. The inside of the reagent bag 4 contains insect and rodent repellents, such as capsaicin, eucalyptus oil, peppermint oil, insecticides, or rat poison. The specific substances added can be determined by the user based on the specific situation. After the reagent bag 4 is installed, the user should open the elastic sleeve 1 and allow it to cover the outer sheath 5. Then, the connecting block 2 fixed to the elastic sleeve 1 should be moved towards the locking block 3 fixed to the elastic sleeve 1, causing the fixing block 12 fixed to the connecting block 2 to slide against the locking groove 11 at the top of the locking block 3. This fixes the elastic sleeve 1 to the surface of the outer sheath 5. At this point, the user can use a screw, inserting it into the inside of the locking block 3 through a round hole on one side. The elastic sleeve 1 is spirally connected to the fixing block 12 with fixing holes 13, thereby further strengthening the fixing effect of the elastic sleeve 1. When the optical cable is attacked by rodents and insects after a long period of use, the outermost elastic sleeve 1 will be the first to be attacked. When the rodents and insects have finished attacking the elastic sleeve 1 and the reagent sac 4, the reagent stored inside the reagent sac 4 will flow out and repel the rodents and insects in the surrounding area, preventing them from further attacking the optical cable and causing greater damage. Then the user can remove and replace the damaged elastic sleeve 1 separately, thereby speeding up the replacement process. The outer sheath 5 is reinforced with aramid fiber, which effectively strengthens the outer sheath 5. The inner side of the outer sheath 5 is provided with a reinforcing layer 6, the inner side of the reinforcing layer 6 is provided with an inner sheath 7, and the inner side of the inner sheath 7 is provided with a filling layer 8. The filling layer 8 contacts the optical fiber body 9.

[0031] In this utility model, the elastic sleeve 1, outer sheath 5, inner sheath 7 and other components are all existing technologies, and their working principle is the same as that of similar products on the market, so they will not be described in detail here.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
