Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to a threaded optical cable reinforcement core. Background Art

[0002] An optical cable is a communication line consisting of a number of optical fibers arranged in a certain pattern, surrounded by a sheath, and sometimes also covered with an outer sheath, to transmit optical signals. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. To enhance the strength of the optical cable, a reinforcing core is required. The basic structure of an optical cable generally consists of a cable core, reinforcing core, filler, and sheath. In some special cases, a higher strength reinforcing core is required. To this end, polyester yarn can be wrapped around the existing reinforcing core, thus creating a spiral reinforcing core. In addition, according to actual needs, there are also components such as waterproof layers, buffer layers, and insulated metal conductors. Optical cables play an indispensable role in the process of information construction. Once damaged, optical cables will suffer serious economic losses and bring inconvenience to our work and life. Therefore, certain measures are taken to protect and improve optical cables to ensure the stability and reliability of communication networks. Traditional optical cable reinforcing cores are mostly internally set, which makes them prone to damage during use. To this end, we propose a threaded optical cable reinforcing core. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a threaded optical cable reinforcement core. The use of a first core body in combination with a second core body can effectively improve the tensile strength and compressive strength, making it less prone to damage, and the corrugated steel belt in combination with a protective sleeve can prevent the optical cable from being worn and punctured during long-term use, which can effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a threaded optical cable reinforcement core, comprising a fixing sleeve and an optical fiber tube;

[0005] Fixed sleeve: A first core body is inserted inside. The first core body is made of wound iron wire. The fixed sleeve and the interior of the plastic-coated aluminum strip form a cavity. The interior of the cavity is filled with a filler. The filler is high-temperature resistant and flame-retardant aramid. The optical fiber tube is evenly inserted into the filler. The interior of the optical fiber tube is filled with grease.

[0006] The second core is evenly distributed inside the filler and is woven from glass fiber and aramid fiber.

[0007] The first core is made of iron wire, which makes the threaded optical cable have higher tensile strength and compressive strength. It is combined with the second core to increase the service life of the threaded optical cable. The filling material can play a role of high temperature resistance and flame retardancy.

[0008] Furthermore, it also includes an electromagnetic shielding sleeve and anti-electromagnetic shielding fiber. The electromagnetic shielding sleeve is sleeved on the outside of the plastic-coated aluminum tape, and the anti-electromagnetic shielding fiber is evenly inserted into the inside of the electromagnetic shielding sleeve. The electromagnetic shielding sleeve and the anti-electromagnetic shielding fiber can effectively resist electromagnetic interference and lightning damage, thereby ensuring the stability and safety of communication, so that the threaded optical cable can be used in different environments.

[0009] Furthermore, it also includes a water-blocking tape, which is evenly distributed on the outside of the electromagnetic shielding sleeve. The water-blocking tape is a non-woven fabric. The water-blocking tape can prevent liquid from penetrating, so that the threaded optical cable has good waterproof performance, corrosion resistance and material safety performance, and can provide protection for the optical threaded cable.

[0010] Furthermore, it also includes a corrugated steel belt, which is fixed on the outer side of the water-blocking belt. The corrugated steel belt is a galvanized steel belt. The corrugated steel belt can effectively prevent the threaded optical cable from being punctured and damaged by sharp objects.

[0011] Furthermore, it also includes a protective sleeve, which is sleeved on the outside of the corrugated steel belt. The protective sleeve is a polyethylene sleeve. The provision of the protective sleeve can increase the service life of the threaded optical cable, thereby preventing the threaded optical cable from being worn.

[0012] Furthermore, it also includes an insect repellent coating, which is evenly coated on the surface of the protective sleeve. The insect repellent coating is a silica inorganic coating. The coated insect repellent coating can prevent the threaded optical cable from being eaten by insects and ants, thereby preventing ants and insects from approaching the threaded optical cable, thereby achieving the purpose of preventing ants and insects from eating the threaded optical cable.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the threaded optical cable reinforcement core has the following advantages:

[0014] 1. The first core is wound with iron wire, which makes the threaded optical cable have higher tensile strength and compressive strength. The second core is used to improve the service life of the threaded optical cable. The filling material can play a role of high temperature resistance and flame retardancy.

[0015] 2. The electromagnetic shielding sleeve and anti-electromagnetic shielding fiber can effectively resist electromagnetic interference and lightning damage, thereby ensuring the stability and security of communication, so that the threaded optical cable can be used in different environments, and the water-blocking tape can prevent liquid penetration, so that the threaded optical cable has good waterproof performance, corrosion resistance and material safety performance, which can provide protection for the optical threaded cable.

[0016] 3. The corrugated steel belt can effectively prevent the threaded optical cable from being punctured and damaged by sharp objects. The protective cover can increase the service life of the threaded optical cable, thereby preventing the threaded optical cable from being worn. BRIEF DESCRIPTION OF THE DRAWINGS
