Abstract
The invention discloses a special high-hardness anti-tortuous optical cable strengthening core and an optical cable using the strengthening core; the optical cable comprises a sheathed cable body, a strengthening piece and optical fibers; the sheathed cable body made of environmentally friendly halogen-free flame retardant high-elastic polyolefin materials has non-toxic environmentally friendly flame-retardant properties and can be applied to indoor laying; the strengthening piece takes aramid fibers as matrix material which then enters a die hole after being impregnated into the ultra-violet composite liquid, finally the material is extruded, stretched and solidified through UV into 0.5mm rod-shaped matrix, with the tensile force reaching more than 1800MPa; a layer of 0.2mm high-hardness bending-resistant and flame-retardant PVC high-elastic material is arranged on the rod-shaped matrix through plastic coating; the layer of material is integrated into the sheathed cable body in a parallel and symmetrical way; the fibers can be one or more in number, with a diameter of 250um; the fibers are made of easily tortuous and insensitive fiber materials; therefore, through the combination of the processes and technologies, the indoor wiring optical cable with the specification of 2 multiplying 3mm achieves high-hardness and anti-tortuous practical effects.
Description
Affiliated technical field
The present invention relates to the house wiring communications optical cable of a kind of apparent size 2 * 3MM, be applicable to the small size optical cable of the terminal wiring of FTTH.
Background technology
Develop rapidly along with society; people increase day by day to the dependence of communication network and information transmission; communication network develops to high capacity and high density direction; in case destroyed; can suffer serious economy loss immediately; make troubles for our life, thereby should take certain measure that optical cable is protected and strengthen improvement, guarantee the long-term unimpeded and reliability of communication network optical cable.
Optical cable product in the market generally includes sheath two parts of cable core and cable core periphery, and it in use usually can run into two kinds of problems, and the one, meeting meets with the biting destruction of animals such as mouse, termite and causes disconnected cable or look-at-me etc.; The 2nd, the tensile force of itself is low, the creasing resistance difference also can cause fibercuts in the cable body and the transmission of interrupting information.
Because the formation Main Ingredients and Appearance of cable core optical fiber is a high-purity quartz glass, the physical property of its stretch-proof, anti-complications is very fragile, thereby ordinary optical cable very easily causes the fibercuts in the sheath in using installation process, and this also is to influence the major obstacle of optical cable to the family popularization and application for many years.
Equally, indoor 2 * 3MM small size optical cable commonly used, the formation Main Ingredients and Appearance of its cable core optical fiber equally also is a high-purity quartz glass, diameter only has 0.25 millimeter, with the general thickness of human body hair, the physical property of its stretch-proof, anti-complications is also very fragile, thereby uses in the installation process and very easily cause fibercuts and damage.Industry is in order to overcome above-mentioned shortcoming; a lot of effort have been done; comprise the optical cable of having invented the aramid fiber strengthening core protection that is added with the replacement glass fibre of using on the present market in the optical fiber both sides; the main composition of this aramid fiber strengthening core be a kind of be reinforcing material with the aramid fiber; thermoset resin is a matrix material; thermoplasticity PE is the fiber reinforced plastics pole body of protective cover material; as Chinese patent CN200410017783.0; its aromatic polyamide optical cable reinforcing core promptly is to adopt above-mentioned structure; its diameter is approximately 0.5MM-0.8MM; this aromatic polyamide optical cable reinforcing core can improve the integrally stretching intensity of optical cable to a certain extent; guarantee that optical cable high-tension performance owing to the aramid fiber in the cable body in construction is used is difficult for being broken; thereby protected the optical fiber in the optical cable to be difficult for being broken; but the anti-tortuous poor performance of this aromatic polyamide optical cable reinforcing core; in construction, run into knotting; bending; during situations such as extruding, above-mentioned aramid fiber strengthening core still can not effectively be protected optical fiber in the cable protecting body.Analyze its chief reason: optical fiber the bending fracture place the R angle less than 1 millimeter, two parallel strengthening cores in its sheath are also fracture simultaneously when the doubling of optical cable angle and curved, because the inside cable sectional dimension is little, cable body sheath elastic force deficiency, can't recover straightened condition rapidly, thereby cause fibercuts in the cable body, its major function of aramid fiber strengthening core in the now general employed house wiring optical fiber cable is for strengthening the tensile force of cable body, prevent that optical cable from pullling fracture, but its weakness is that (less than 30 millimeters) very easily rupture and lose again straight elasticity when bending radius is too small.Therefore, the optical cable of existing aromatic polyamide optical cable reinforcing core protection exists shortcomings such as anti-tortuous poor performance, the little easy fracture of bending angle.
Summary of the invention
In order to solve the problem described in the background technology, the present invention's a kind of special high-strength bend resistance optical cable strengthening core and use the optical cable of this strengthening core, the constituent material of described strengthening core comprises the elasticity height, the polyester aramid fiber wire material that the coefficient of tension is big, to be matrix enter die hole extrusion stretching UV ultraviolet light polymerization equipment to described strengthening core behind ultraviolet light polymerization complex liquid dipping be cured as the shaft-like matrix of 0.5mm with the aramid fiber tow, its pulling force is reached more than the 1800mpa, and the flame-proof PVC highly elastic material of the anti-bending of high rigidity of the plastic one deck 0.2mm of heat on shaft-like matrix, being integrated in the sheath cable body of its parallel symmetry; The optical cable of described this strengthening core of use roughly becomes rectangular parallelepiped, and it comprises being integrated in two special high-strength bend resistance aromatic polyamide optical cable reinforcing cores in the sheath cable body and being integrated in the optical fiber that is used to protect in the sheath cable body between the cable strengthening core of sheath cable body, symmetry.Its sheath cable body selects for use environmental protection grade non-halogen flame-retardant high-tension polyolefine material to make, its optical fiber can be one or for many, all adopting diameter is 250um, easily shellfish bend-insensitive fiber optic materials is made, the use of comprehensive above technology makes this specification to be that the house wiring optical fiber cable of 2 * 3mm has been realized extraordinary, the practical function of high strength, anti-complications.
The invention has the beneficial effects as follows, this special high-strength bend resistance aromatic polyamide optical cable reinforcing core and use the optical cable of this strengthening core, it is little to have bending radius, anti-folding, and size is little by (2 * 3mm), weight is slim and graceful, transport information capacity is big, speed is fast, and installation is laid very convenient, long service life, more be applicable to building, hotel, office, indoor scenarios such as warehouse.
