Description
Technical field
The utility model relates to the Optical Fiber Transmission field, and espespecially a kind of optical fiber protecting equipment, be specifically related to a kind of optical fiber protecting equipment.
Background technology
The complete name of optical fiber is called light transmitting fiber, with pure quartz, with special technique, pulls into filament, and its diameter is also thinner than hairline.Light beam transmits in glass fibre, and signal is not subject to the interference of electromagnetism, and transmission is stable.Have dependable performance, quality is high, and speed is fast, the characteristics such as line loss is low, long transmission distance, suitable express network and backbone network.Optical fiber is a kind of transmission medium, is to manufacture according to the principle of the total reflection of light.Optical fiber is a kind of medium of the other end that message is sent to from an end, is one and usings glass or plastic cement fiber as the transmission medium that allows message pass through.Usually optical fiber and two nouns of optical cable can be confused.Most optical fiber must protect structure to coat by which floor before use, and the cable after coating is called as optical cable.The protection structure of fiber outer layer can prevent the injury of context to optical fiber, as water, and fire, electric shock etc.Optical cable is divided into: optical fiber, cushion and coating.Optical fiber is similar with concentric cable, just there is no the mesh shields layer.Center is the glass core that light is propagated.In multimode optical fiber, the diameter of core is 15mm ~ 50mm, roughly suitable with the thickness of people's hair.And the diameter of single-mode optics fibre core is 8mm ~ 10mm.The core surrounded the glass big envelope that one deck refractive index ratio core is low, so that optical fiber remains on in-core.Outside is the plastic wrapper that one deck is thin again, is used for protecting big envelope.Optical fiber is bundled into bundle usually, and there is the shell protection outside.The double-deck concentric cylinder that the cross-sectional area that fibre core is normally made by quartz glass is very little, its quality is crisp, and therefore easy fracture needs an additional protective seam.
In prior art, electric system is for building the strategic development target of strong intelligent grid, accelerate research application New Technologies of Electric Power Transmission and advanced control, measurement, information, the communication technology, further improve the ability of controlling short-term load, ensure power network safety operation.Electricity Departments are studied the T & D Technology that many nets merge in recent years for this reason, one of them is exactly the technology of transmission of electricity that research transmission of electricity, communication, observing and controlling etc. are merged, the optical fiber composite wire occurred for the transmission that takes into account light signal and electric energy, OPPC is exactly the technology that wherein represents, he is integrated the technological incorporation such as electricity, communication, observing and controlling, thermometric.Optical fiber composite wire obtains the use of power consumer just gradually, and the optical fiber in compound wire is in a metal tube, when continuing, fiber section need to be stripped out, and then carries out fused fiber splice and continues.The major defect that existing compound wire continuation method exists is: because metal pipe-wall is very thin, the opening's edge place forms blade, and optical fiber is very very thin and fragile, be easy to be cut off at metal tube opening's edge place, and compound wire can be used at the not a large amount of remaining cables of splicing point, once optical fiber is cut off, just likely cause whole strain section wire to scrap, need to again change whole strain section compound wire, material cost, executive cost all can have very large expenditure like this.Simultaneously due to the optical fiber protecting equipment tension of prior art and lateral pressure resistant intensity is low, thermal shrinkage large, optical fiber is worn fine difficulty, affected using and promoting of optical fiber.If it will be to need the basic defect solved in prior art that a kind of protective sleeve that can protect the optical fiber metal mouth of pipe can also protect inside of optical fibre simultaneously can be provided.
The utility model content
For above-mentioned technical matters; the utility model provides a kind of technological process simple; equipment is stable, safe and reliable to operation, there is tension simultaneously and lateral pressure resistant intensity is high, thermal shrinkage is little, optical fiber wear fine convenient, wear that fine efficiency is high guarantees that the pipeline metal mouth of pipe is difficult for the optical fiber protecting equipment cut off.
For solving the problems of the technologies described above; the utility model provides a kind of optical fiber protecting equipment; comprise body; it is characterized in that: described body is comprised of slim protective sleeve, the aramid fiber reinforcing sleeve arranged successively from outside to inside and the optical fiber protective tube of being made by thermoplastic elastic material; the tube chamber inside of described optical fiber protective tube arranges metal tube, and described metal tube arranged outside has joint protective sleeve.
As further improvement of the utility model, the external diameter of described optical fiber protective tube is 0.5 ~ 1.5mm.。
As further improvement of the utility model, the external diameter of described aramid fiber reinforcing sleeve is 1.0 ~ 2.5mm.
As further improvement of the utility model, the external diameter of described slim protective sleeve is 2.0 ~ 3.5mm.
As further improvement of the utility model, the lumen wall of described optical fiber protective tube is friction surface, with metal tube, adopts socket to be connected.
As further improvement of the utility model, that described joint protective sleeve shape comprises is trapezoidal, wherein a kind of in rectangle, stepped ramp type.
The utility model compared with prior art has following beneficial effect:
1. body of the present utility model is comprised of PVC protective sleeve, the aramid fiber reinforcing sleeve arranged successively from outside to inside and the optical fiber protective tube of being made by thermoplastic elastic material, the optical fiber protective tube band is useful on the tube chamber of placing protected optical fiber, adopt the stock of thermoplastic elastomer (TPE) material as optical fiber protective tube, make protection tube there is certain tension, lateral pressure resistant intensity; Optical fiber protective tube adopts tubular structure, makes the change in size of optical fiber protective tube very little, and it is fine convenient to wear, and thermal shrinkage is very little, there is tension and lateral pressure resistant intensity is high, thermal shrinkage is little, optical fiber wear fine convenient, to wear fine efficiency high.
2. joint protective sleeve of the present utility model is made by the PE material, has stronger shrinkability, thereby reduces along locating to form the elastic shock attenuation circle phenomenon of being cut off at metal tube opening's edge place caused because optical fiber metal tube head is very thin at the metal tube draught animals.
3. technological process of the present utility model is simple, and equipment is stable, safe and reliable to operation, is convenient to a large amount of production and applications.
