Description
Technical field
The utility model relates to a kind of indoor optical cable, more particularly to a kind of nonmetallic indoor optical cable of helix tube type,
Belong to optical cable technology field.
Background technique
Inside cable is the optical cable being laid in building, the communication equipment being mainly used in building, computer, exchange
Machine and the equipment of terminal user etc. are also high to performance requirement by building or use environment is limited.
Existing inside cable, typical structure have butterfly-type optical cable, covered wire cable, and the ribbon spiral pipe developed in recent years
The inside cable of formula.Butterfly-type optical cable, flexibility, bendability and lateral pressure resistant are all poor；Covered wire cable, flexibility, good bandability resist
Side pressure is poor；The inside cable of ribbon spiral tubular type, flexibility, bendability and lateral pressure resistant are all preferable, but the easy injured in joint
Optical fiber, and because containing steel, be not suitable for applying in strong-electromagnetic field environment, exist if steel part electrification when being contacted with equipment metal
Electrical safety problem.In addition, butterfly-type optical cable, covered wire cable all are also easy to be bitten by mouse that fiber optic communication is caused to interrupt, and
The inside cable of ribbon spiral tubular type has excellent mouse bite preventing ability.
For this purpose, being directed to the deficiency of existing indoor optical cable technology, a kind of flexibility, bendability and lateral pressure resistant are developed all
Good, electrical safety is good, is suitble to the nonmetallic inside cable applied in strong-electromagnetic field environment, becomes and develops production in recent industry
A kind of trend of product.
Summary of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of nonmetallic room of helix tube type
Interior to use optical cable, flexibility, bendability and lateral pressure resistant are all good, Electrical Safety, are suitble to the non-gold applied in strong-electromagnetic field environment
Belong to inside cable, to improve the safety and reliability of system.
According to technical solution provided by the utility model, the nonmetallic indoor optical cable of helix tube type comprising helix tube, tight
Packet optical fiber, aramid fiber, reinforcer and oversheath include one or several tightly packaged fibers and aramid fiber, the spiral shell in the helix tube
Successively packet carries out reinforcer and oversheath from inside to outside outside coil: the aramid fiber is longitudinally placed in parallel with tightly packaged fiber；The spiral shell
The cross section of coil is rectangular ribbon, is wound into hollow tube in a helical pattern, and there are equidistant between ribbon
Gap.
As a further improvement of the utility model, the equidistant gap be ribbon rectangle length four/
Between 3/1sts to four.
The helix tube material therefor includes nylon, polyester, nylon and aramid fiber as a further improvement of the utility model,
Or one or more of combinations of the compound, carbon fiber of compound, polyester and the aramid fiber or Polyester Yarns of Polyester Yarns.
The oversheath is to extrude plastics or Polyurethane or rubber-plastic elastomer as a further improvement of the utility model,.
As a further improvement of the utility model, the reinforcer be aramid fiber or polyester or terylene one or more or
A combination thereof.
It is wrapped or braiding that the reinforcer packet, which carries out mode, as a further improvement of the utility model,；Its wrapped side
To opposite with the hand of spiral of helix tube.
Compared with the prior art the utility model has the advantage that
Utility model has the advantages that providing a kind of nonmetallic indoor optical cable of helix tube type, on the one hand, use
The helix tube of high-intensitive, good toughness nonmetallic materials, it is anti-improving optical cable for protecting the tightly packaged fiber of cable interior structure
Optical cable is made to be provided with excellent bending property again while side pressure strength；On the other hand, aramid fiber and reinforcer conduct are used
Load-carrying unit further improves the endwise tensile strength and whole mechanical and physical performance of optical cable.In another aspect, due to including spiral shell
All material including coil is all nonmetallic insulator, and the optical cable enable uses in the environment of strong-electromagnetic field, especially suitable
Share the places such as high voltage power transmission and transforming institute；Simultaneously again because light-weight, outer diameter is small, it is suitable as the indoor optical cable with Optical fiber plug.Separately
Outside, so that mouse stings the helix tube of motionless high intensity, make the anti-rat that optical cable is excellent.
The advantage of above-mentioned several respects, the nonmetallic indoor optical cable of helix tube type, existing excellent flexibility, bending
Property, lateral pressure resistant and the advantages of Electrical Safety, facilitate construction lay and it is mobile use, be suitble to large-scale promotion application, have and produce
Very high utility value in industry.
