Description
Technical field
The utility model is related to inside and outside a kind of rectangular chamber of the communications field more particularly to indoor and outdoor optical signal transmission two
With communication covered wire cable.
Background technology
With making rapid progress for the communication technology, small, long length of decaying to the large information capacity transmission of communication network and signal
Every technology requirement such as transmission is higher and higher；Meanwhile national resource of advocating thriftiness energetically, light entering and copper back, it would be desirable to find one kind
Good communication quality, cost is relatively low, and previous coaxial cable signal transmission is substituted convenient for the novel product of construction.
Communicate covered wire cable, is to carry out signal transmission with the optical signal of total reflection, there is transmission to contain much information, decay it is small,
The advantages of conveying length is long, from Electromagnetic Interference；However, outdoor aerial and interior can be applied to simultaneously by having not yet to see
The high-capacity optical cable of wiring；It is necessary to be researched and developed.
Utility model content
The purpose of the utility model is to overcome the deficiencies of above-mentioned background technology, provide a kind of indoor and outdoor dual-purpose communication rubber-insulated wire light
Cable, the optical cable should have the characteristics that indoor and outdoor is applicable in, is easily installed and highly practical simultaneously.
Technical solution provided by the utility model is：
Dual-purpose communication covered wire cable inside and outside rectangular chamber, including be arranged parallel to and be arranged in a row optical fiber, strengthen
Part and reinforcement self-supporting steel wire；It is characterized in that：The optical fiber includes three pairs of light arranged for interval between four groups of reinforcers
Fibre separately carries out injection positioning by section for rectangular oversheath.
Oversheath is fire-retardant PE oversheaths；Surface of outer sheath, which is provided with, several easily tears V-shaped groove.
Each easily tear V-shaped groove is correspondingly arranged a pair of of optical fiber respectively；To be easy to that optical fiber is exposed in the construction process, and it is unlikely
In destruction reinforcer.
The reinforcement material is nonmetallic materials or phosphating steel wire.
The reinforcement self-supporting steel wire is individual wire or steel wire strand；Branch during aerial laying can effectively be enhanced
Support force, protection optical fiber are unlikely impaired.
The beneficial effects of the utility model are：Three pairs of optical fiber combinations of rectangular configuration provided by the utility model, by room
Inside and outside cabling requirement perfect adaptation together, not only saves jacket material, but also construction is brought convenience, and practicability is stronger；Together
When can introduce 3 groups of optical signals, significantly increase working transmission；Trunk cable need not be re-introduced into, it is disposable to install, so that it may real
Existing signal of communication enters village and enters effective transmission that area registers one's residence.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
In figure：1 is reinforcer, and 2 be optical fiber, and 3 be fire-retardant PE sheaths, and 4 be V-arrangement tearing groove, and 5 be reinforcement self-supporting steel wire.
Specific embodiment
It is further illustrated below in conjunction with embodiment shown in the drawings.
Dual-purpose communication covered wire cable inside and outside rectangular chamber shown in the drawings, including optical fiber, the reinforcer being arranged parallel to
And strengthen self-supporting steel wire；These are similar with existing covered wire cable.
The improvement of the utility model is：The optical fiber includes three pairs of optical fiber and four groups of reinforcers, and each pair optical fiber is by two
Optical fiber composition side by side；Three pairs of optical fiber are arranged in a row with four groups of reinforcers, and (optical fiber is generally high-purity to spaced arrangement
Silica), separately injection positioning is carried out for rectangular oversheath by section.
Oversheath is fire-retardant PE oversheaths；Surface of outer sheath, which is provided with, several easily tears V-shaped groove.
Each easily tear V-shaped groove is correspondingly arranged a pair of of optical fiber respectively.Easily V-shaped groove will be torn in work progress to tear, it just can be easily
Ground is exposed by optical fiber, without destroying reinforcer；Thus convenience is brought to construction.
Reinforcement material can be nonmetallic materials or phosphating steel wire.The elasticity modulus of reinforcer 80GPa with
On, optical fiber can be made to be damaged from the influence of external force.
The reinforcement self-supporting steel wire, can be individual wire or steel wire strand；When can effectively enhance aerial laying
The mechanical performances such as tension, tension, it is ensured that internal optical fiber is without any damage.
During making, first optical fiber surface is coloured, coats layer protective layer；Then designed rectangle extrusion molding mould is passed through
Tool, by 6 core fibres, 4 reinforcements, a reinforcement self-supporting steel wire is parallel to enter mold, outside uniform one layer of fire-retardant PE of extrusion molding
Sheath, once-forming is rectangle；Sheath material can be effectively saved, while facilitates installation.
When the utility model manufactures, key is optical fiber coloring, multiply material extrusion molding simultaneously, rectangular die design.It will
It asks in optical fiber surface uniform coloring, bias is not allow in coloring process, optical fiber is damaged, section lines, and solidification effect will be got well.
During fire-retardant PE sheaths are extruded, sheath should be coated to optical fiber, cannot be damaged, while optical fiber, reinforcement
Part strengthens cannot having infiltration between self-supporting steel wire and sheath, and various assemblies are existed by designed square extruded mould uniform combination
Together.The plasticizing of sheath appearance requirement is good, smooth, uniform, consistent.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this practicality is new
Type is not limited to above example, can also there is many variations.Those of ordinary skill in the art can be from disclosed in the utility model
All deformations for directly exporting or associating in content, are considered as the scope of protection of the utility model.
