Abstract
Novel optical cable. The utility model provides a simple structure improves life's novel optical cable. The cross -section of optical cable is the ellipse, including PVC sheath, kevlar silk, spring wire and a pair of optic fibre, optic fibre include the fibre core with and seal the PE sheath outside the fibre core, a pair of optic fibre is established symmetrically in the PVC sheath, kevlar silk and spring wire establish respectively in the PVC sheath, and be located between a pair of optic fibre. The utility model discloses set up the kevlar silk in the optical cable, strengthened the tension stress and the compliance of optical cable, set up spring wire and have better elasticity and design function, avoid the optical cable crooked impaired many times. A pair of optic fibre is connected through gomphosis structure (being the sawtooth gomphosis), has improved joint strength between them, forms wholly, has improved life. The utility model provides an optical cable is with low costs, light in weight and tensile can the reinforces.
Description
Technical field
The utility model relates to communication technical field, particularly relates to optical cable.
Background technology
Optical cable is that the optical fiber of some forms the cable heart according to certain way, is surrounded by sheath outward, the also coated outer jacket had, in order to realize a kind of communication line of optical signal transmission.Along with informationalized development, the conveying capacity of information increases rapidly, and optical fiber cable obtains a large amount of application.The cable configuration used at present is comparatively simple, this optical cable is made up of single core tight tube fiber and the restrictive coating being coated on single core tight tube fiber surface, the production technology of this optical fiber is comparatively simple, the bad mechanical property of optical fiber, in construction or use procedure, easily cause the bending of optical fiber or fracture, finally cause the Transmission of light signal, have a strong impact on the long-time stability of optical fiber transmission property.
Utility model content
The utility model, for above problem, provides a kind of structure simple, improves the Novel optical cable in serviceable life.
The technical solution of the utility model is: the ellipsoidal cross section of described optical cable, comprise PVC sheath, Kevlar fiber, spring steel wire and a pair optical fiber, described optical fiber comprise fibre core and and the PE sheath that is encapsulated in outside fibre core, optical fiber described in a pair is located in described PVC sheath symmetrically, and described Kevlar fiber and spring steel wire to be located in described PVC sheath and respectively between a pair optical fiber.
Connected by embedded structure between the PE sheath of a pair optical fiber, described embedded structure is: the inner side of a pair PE sheath is respectively equipped with the sawtooth staggered.
Described fibre core material is polymethylmethacrylate.
Described PE sheath is provided with the storage tank placing Kev wire drawing.
The utility model arranges Kevlar fiber in optical cable, enhances tension stress and the flexibility of optical cable; Spring steel wire is set there is good retractility and shapping function, avoid optical cable repeatedly bending impaired.A pair optical fiber is connected by embedded structure (namely sawtooth is fitted together to), improves both strength of joint, is formed overall, improve serviceable life.Optical cable cost in the utility model is low, lightweight and resistance to tension is strong.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the structural representation of embedded structure in the utility model,
Fig. 3 is the syndeton schematic diagram of PE sheath and Kevlar fiber in the utility model;
In figure, 1 is PVC sheath, and 2 is Kevlar fibers, and 3 is optical fiber, and 31 is fibre cores, and 32 is PE sheaths, and 4 is sawtooth, and 5 is storage tanks, and 6 is spring steel wires.
Embodiment
The utility model as Figure 1-3, the ellipsoidal cross section of described optical cable, comprise PVC sheath 1, Kevlar fiber 2, spring steel wire 6 and a pair optical fiber 3, described optical fiber 3 comprise fibre core 31 and and the PE sheath 32 that is encapsulated in outside fibre core 31, optical fiber 3 described in a pair is located in described PVC sheath 1 symmetrically, and described Kevlar fiber 2 and spring steel wire 6 to be located in described PVC sheath 1 and respectively between a pair optical fiber 3.Kevlar fiber and spring steel wire can be symmetrical arranged, and also can be arranged on homonymy.
Kevlar fiber 2 improves tension stress, the flexibility of optical cable, weight reduction; Spring steel wire has good retractility and shapping function, avoids optical cable repeatedly bending impaired.
Connected by embedded structure between the PE sheath 32 of a pair optical fiber 3, described embedded structure is: the inner side of a pair PE sheath 32 is respectively equipped with the sawtooth 4 staggered; Be fitted together to by the sawtooth staggered, make a pair optical fiber form entirety, improve intensity, improve serviceable life.
Described fibre core 31 material is polymethylmethacrylate.
Described PE sheath 32 is provided with the storage tank 5 placing Kev wire drawing, is placed on by Kevlar fiber in storage tank, reliably locates, and improves optical cable flexibility.
