Description

[Technical field]

[0001] The utility model relates to the technical field of optical fiber cables, in particular to a non-contact glass yarn hand-piercing and mouse-proof optical cable. [Background Technology]

[0002] With the development of the times, the awareness of protecting humanity and the environment during the construction of optical cables has been increasing year by year. Therefore, how the optical cables are friendly to the environment during their construction and how they enhance the "happiness" of construction personnel are also becoming more and more important to major operators.

[0003] Therefore, most optical cables currently use glass yarn as a cheap and effective reinforcement element, which can reduce costs and have a rat-proof function. However, glass yarn will bring a construction problem. During the construction process, it will produce flying silk or debris, which will cause environmental pollution and construction workers' hands to be pierced. It can be seen that a construction-friendly optical cable will become more and more popular in the market. The optical cable must be quickly deployed and have excellent mechanical properties. At the same time, the glass yarn reinforcement must not be exposed to the environment during the construction process, so as not to hinder the construction efficiency. The above points are the key to the development of this type. [Contents of the utility model]

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0034] The non-contact anti-glass yarn hand-piercing and anti-rat optical cable described in the utility model mainly includes an optical fiber unit, a basic reinforcement element, a main sheath element, a partitioned glass yarn reinforcement, a hot melt adhesive in a specially shaped cavity, a special funnel crack structure, and a polyester serrated belt that serves as a connecting belt structure. Among them, the optical fiber unit can use a thermoplastic elastomer tight-wrapped material, or a multi-core bare fiber structure can be used as a communication optical fiber unit. The basic reinforcement element can use traditional aramid as a reinforcement element, or a metal armor can be used as a basic reinforcement element. The specially shaped cavity is filled with a special low-temperature, easy-to-melt hot melt adhesive as a penetration material. The funnel direction of the special crack funnel structure points to the partitioned glass yarn reinforcement, and there can be one or more cracks in the area. The angle between the crack surface one and the crack surface two is preferably set to 60°. The polyester serrated connecting belt structure adopts a polyester film belt, and is serrated. The angle between the tooth structures is preferably 135°, and it is connected and spliced ​​with a special split funnel structure. The wall thickness of the film polyester belt is 0.1-0.3mm, and the thickness is preferably 0.2mm. The glass yarn area composed of the special shape cavity, the connecting belt structure, and the special split funnel structure has at least two reinforcement layers, and is layered and staggered to surround the optical fiber unit to form a 360° surrounding structure. The sheath structure can be made of low-smoke halogen-free material, polyethylene material, or other polymer cable sheath materials. The sheath structure seals the cavity filled with hot melt adhesive, the partitioned glass yarn and the optical fiber unit, and it can be integrally formed.

[0035] As attached Figure 1As shown, the basic reinforcement elements are distributed around the periphery of the optical fiber unit. The basic reinforcement elements, the cavity filled with hot melt adhesive, and the glass yarn partition unit are tightly wrapped by the outer sheath. The optical fiber unit can be set as a tight fiber structure or a multi-core bare fiber structure. The number of cores can range from single core to 12 cores. The basic reinforcement elements can be traditional aramid reinforcement elements or metal armor reinforcement elements. A fan-shaped area is arranged around the optical fiber unit and the basic reinforcement element. The fan-shaped area is composed of a partitioned glass yarn unit, a cavity filled with hot melt adhesive, a special crack unit, and a polyester toothed connecting belt. The fan-shaped structure composed of the above is evenly distributed around the central layer, and the fan-shaped area can be 2 to 8, providing tension for the optical cable. The polyester toothed connecting belt connects the special crack unit and the cavity filled with hot melt adhesive, and separates the partitioned glass yarn unit in half on the left and right. The outer sheath unit can be made of low-smoke halogen-free material or polyethylene material, or other polymer cable sheath materials.

[0036] As attached Figure 2 As shown, the cavity filled with hot melt adhesive, the special crack funnel unit and the glass yarn partition unit constitute the key part of the glass yarn anti-prick. First of all, the glass yarn is partitioned and completely wrapped by the sheath. This design method fully ensures that during the construction process, the glass yarn can be completely separated in clusters, rather than loose and in direct contact, which greatly reduces the risk of direct contact. In addition, the hot melt adhesive is set to become a fluid when heated, flow into the glass yarn, and soak the glass yarn. After room temperature, the soaked glass yarn will become a whole block instead of a loose state. The implementation method described above only requires the construction personnel to preheat the stripping section of the optical cable during the construction process, and construction can be carried out after cooling. If the glass yarn is accidentally exposed during the stripping process under special circumstances, the glass yarn will be in blocks due to the above mechanism, and there will be no slag or flying wires, avoiding the problem of pricking hands. In order to better infiltrate the glass yarn, a special slit funnel unit and a polyester toothed connecting belt are specially designed. The two angled surfaces of the special slit funnel unit form an angle of 60°, so that the hot melt adhesive can effectively and quickly penetrate into the direction of the glass yarn.

[0037] The polyester toothed connecting belt plays a role in drainage and helps the hot melt adhesive to infiltrate the glass yarn. The polyester belt is serrated, and the angle between the serrations is 135°. The above shape and angle design increase the contact surface and contact effect between the hot melt adhesive and the glass yarn, ensuring that the hot melt adhesive can completely infiltrate the glass yarn, so that the glass yarn will not fall off or have flying threads after cooling and solidification, achieving the purpose of preventing the glass yarn from being pierced. There is a synergistic effect between the polyester toothed connecting belt and the special slit funnel unit. During construction, the construction personnel heat the stripped section of the optical cable and squeeze the optical cable appropriately. During the squeezing process, the slit unit will crack, and the bond between the polyester belt and the sheath will also be separated. At this time, the hot melt adhesive in a fluid state will flow into the partitioned glass yarn along the polyester belt and fully infiltrate it. The polyester belt also divides the glass yarn into two parts for infiltration, greatly improving the infiltration efficiency.

[0038] The sheath structure can be made of low-smoke halogen-free material or polyethylene material, or other polymer cable sheath materials. It has the characteristics of high temperature resistance and oil corrosion resistance, ensuring the shape stability of the optical cable and the reliability of long-term use.

[0039] Compared with the traditional optical cable rod-proofing, the utility model has its own unique flexibility and can be used in various laying pipelines. Traditional optical cables are mostly flat FRP twisted around the optical fiber unit, but due to its strong rigidity, the bending performance of the entire cable is poor. Therefore, although the use of glass yarn can solve the bending performance problem, the problem of falling slag and flying threads is difficult to solve. The utility model takes a different approach. First, it uses a multi-layer glass yarn wrapping form to protect the optical fiber unit from being bitten by rats at 360°, achieving the effect of flat glass rod wrapping; secondly, the glass yarn has its softness and can adapt to the turning angles of various laying pipelines; the use of hot melt adhesive to solidify the glass yarn can also well solve the problem of glass yarn falling slag and flying threads.

[0040] The utility model optical cable is a kind of optical cable with humanized construction, low price, high strength and wide applicability. It has its own unique structure, fully demonstrates the utility model idea of ​​optical cable anti-prick hand, and achieves the design result.
