Abstract
The utility model relates to a signal transmission line, in particular relates to a communication optical cable and is to provide a central bundle tube type 8-shaped communication optical cable which has the characteristics of high tensile strength, convenient installation and a simple structure. The technology scheme of the utility model is that the central bundle tube type 8-shaped communication optical cable comprises a loose bushing, a waterproof tape, a steel tape and an oversheath successively coated on a plurality of parallel optical fibers from inside to outside; and fiber paste is filled between the optical fibers and the loose bushing. The 8-shaped communication optical cable is characterized in that two steel wires and an optical cable axis are symmetrically mounted, the two steel wires are buried in the oversheath, a suspension wire with a coating sheath is disposed on the optical cable in parallel, the sheath of the suspension wire and the oversheath are integrated by a suspension neck.
Description
Technical field
The utility model relates to a kind of signal transmssion line, specifically is a kind of communications optical cable.
Background technology
Along with making rapid progress of the communication technology, have transmission contain much information, decay little, transmission range long and be not subjected to the optical cable of advantages such as Electromagnetic Interference to be widely used in the communications field, and progressively replaces traditional copper cable.But optical fiber is because tensile strength is limited and impaired easily, extra support apparatus need be set when arranging reinforce (for example self-supporting steel wire) built on stilts, not only increased wiring cost, also promoted installation workload.
The utility model content
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of central beam tube type 8 word communications optical cables are provided, and this optical cable should have tensile strength height, easy for installation and characteristic of simple structure.
The technical solution of the utility model is: central beam tube type 8 word communications optical cables, this optical cable comprises from inside to outside coated loose sleeve pipe, waterstop, steel band and oversheath outside some are arranged in parallel optical fiber successively, fill fine cream between described optical fiber and the loose sleeve pipe, it is characterized in that: bury two steel wires with this optical cable axis symmetric arrangement in the described oversheath underground; Also be arranged in parallel on this optical cable messenger wire of a coated sheath, the sheath of described messenger wire and described oversheath are connected as a single entity by hanging neck.
Described messenger wire and steel wire are the phosphatization steel wire.
Described oversheath is that tygon or low smoke and zero halogen protective cover material are made.
Described waterstop is that expansion water strip or water blocking yarn are made.
The beneficial effects of the utility model are: the utility model is by adding a load-supporting part at optical cable, make the tensile strength ability of optical cable significantly strengthen, can be laid on built on stilts zone separately, need not mounting support equipment separately, not only relatively simple for structure, saved production cost greatly, and installation process is very convenient, has also saved installation workload.
Description of drawings
Fig. 1 is main TV structure synoptic diagram of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, central beam tube type 8 word communications optical cables, this optical cable comprises optical fiber 1, loose sleeve pipe 3, waterstop 4, steel band 5 and oversheath 6.
Some optical fiber is arranged in parallel and is coated by loose sleeve pipe, and optical fiber is generally highly purified silicon dioxide and makes; Filled by fine cream 2 between optical fiber and the loose sleeve pipe, fine cream can improve the pliability of optical cable, optical fiber is freely stretched in loose sleeve pipe and is difficult for impaired.
The pine sleeve pipe is coated waterstop, steel band and oversheath successively outward; Waterstop is generally expansion water strip or water blocking yarn, and waterstop closely is wrapped in outside the loose sleeve pipe, can play waterproof action; Steel band is steel-plastic composite steel belt, can increase resistance to compression and the tensile strength of optical cable, and protection optical fiber is not subjected to external impacts and damages; Oversheath is that tygon or low smoke and zero halogen protective cover material are made, and by the extruded mould once-forming, whole plasticizing is good, smooth in appearance, thickness uniformity.
Above structure is same as the prior art.Improvements of the present utility model are:
Be embedded with two steel wires 7 with optical cable axis symmetric arrangement in the oversheath, steel wire is generally the phosphatization steel wire.A messenger wire 8 that also be arranged in parallel on the optical cable, the outer coaxial coated sheath 9 that has of messenger wire, sheath and oversheath are connected as a single entity by hanging neck 10; Messenger wire is identical to the distance of every steel wire, has strengthened bulk strength and the stability of optical cable greatly.
The utility model adds earlier and puts steel wire and messenger wire when making oversheath and sheath, then by 8 font extruded mould once-formings, has formed the xsect of 8 word structures; The utility model when mounted just separates optical cable and messenger wire by tearing oversheath with the neck that hangs between the sheath, and is very convenient.
