To guard him painted optic fibre of pine cover, the pine sheathed tube outside sets up the reinforcement of being made by phosphating steel wire and the combination of high -modulus kaifula aramid fiber, and the outside of reinforcement is equipped with the oversheath layer. It has good resistance to compression, anti tensile strength, can hold more fiber core numbers, realizes large capacity transmit information, has good protection against the tide, the performance that blocks water.
Description
Technical field
This utility model relates to communications optical cable technical field, especially relates to a kind of high intensity indoor branching optical cable.
Background technology
Inside cable is applied in indoor environment, and size is little, lightweight, and softness, bending resistance are to facilitate wiring, it is easy to branch,
And there is good fire resistance etc..It is generally divided into multi-purpose indoor optical cable, branched cable and interconnection cable.Wherein, branch's light
Cable is conducive to each optical fiber separate cabling and branch, in the pipeline being generally laid between building under congealing point line, in building
In gug, under access floor and fiber to the desk is used.But, the structural strength of existing indoor branching optical cable is on the low side,
The optical fiber destruction from mechanical pressure cannot be effectively protected, and, block-water performance is poor, subjects to the shadow of the pernicious environment such as humidity
It is poor that pilot causes laser propagation effect.
Utility model content
This utility model is for the deficiencies in the prior art, and technical problem to be solved is to provide a kind of high intensity indoor and divides
Drawing optical cable, it has excellent resistance to compression, tensile strength, it is possible to accommodate more fiber number, it is achieved high capacity transmission is believed
Breath, the performance there is good protection against the tide, blocking water.
This utility model is to make above-mentioned technical problem be addressed by the following technical programs.
High intensity indoor branching optical cable, draws aramid fiber fine including colored optical fiber, Loose tube, phosphating steel wire, high-modulus Kev
Peacekeeping external sheath layer, is provided with some colored optical fibers and goes along with sb. to guard him the fine cream of colored optical fiber in Loose tube, the outside of Loose tube is arranged
Being drawn aramid fiber to combine the reinforcement made by phosphating steel wire and high-modulus Kev, the outside of reinforcement is provided with external sheath layer.
As preferably, external sheath layer is low smoke and low halogen soft PVC.
As preferably, a diameter of 0.5mm of phosphating steel wire.
As preferably, Loose tube uses the center beam tube of macromolecular material.
As preferably, between reinforcement and external sheath layer, it is provided with water blocking tape layer.
As preferably, water blocking tape layer is two-sided non-woven fabrics waterstop.
As preferably, being provided with enhancing yarn between water blocking tape layer and external sheath layer, strengthening yarn is aramid fiber yarn or glass fibers
Dimension yarn.
As preferably, strengthen yarn and be provided with tear rope.
As preferably, the outside of external sheath layer is provided with protection against rodents dope layer.
The beneficial effects of the utility model:
1. overall structure is the compactest, it is easy to processing and manufacturing, and production technology is simple, equipment investment low cost.
2. density is little, lightweight, and the reinforcement using phosphating steel wire and high-modulus Kev to draw aramid fiber combination to make makes
Structure is more stable, mechanical strength is higher, digital preservation optical fiber is from stress influence or bears extremely low stress, effectively avoids
Fibercuts damages, and significantly enhances resistance to compression and tensile strength, short-term and long-term tensile strength and can reach 2200 Ns
Above, the problem effectively solving the hot strength deficiency that single use reinforcement brings, the technology meeting house wiring is wanted
Ask.
3. use the Loose tube of macromolecule macromolecular material to possess effective comprcssive strength, and more light can be accommodated
Fibre core number, it is achieved jumbo transmission information.
4. filling fine cream in Loose tube to be conducive to protection against the tide, block water, blocking water in conjunction with two-sided non-woven fabrics further increases resistance
Aqueous energy, guarantee bare fibre it is decayed and transmits unaffected under certain External Force Acting simultaneously, has relative to tightly packaged fiber
There is bigger advantage.
5. external sheath layer uses low smoke and low halogen soft PVC, and uvioresistant, waterproof mildew-resistant, environmental stress resistance is opened
Splitting, good bandability, environmental protection flame retardant function admirable, service life is long.
6. the outside at external sheath layer arranges protection against rodents dope layer and has possessed certain rodent-proof characteristic.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-colored optical fiber, 2-Loose tube, 3-phosphating steel wire, 4-high-modulus Kev draws aramid fiber, 5-oversheath
Layer, 6-fibre cream.
Detailed description of the invention
Below by embodiment and combine accompanying drawing this utility model is described in detail.
This utility model high intensity indoor branching optical cable as shown in Figure 1, including colored optical fiber 1, Loose tube 2, phosphatization
Steel wire 3, high-modulus Kev draw aramid fiber 4 and external sheath layer 5, arrange some colored optical fibers 1 and go along with sb. to guard him in Loose tube 2
The fine cream 6 of coloured light fibre 1, Loose tube 2 preferably employs the central beam tubular construction of macromolecular material, makes optical cable possess effective pressure resistance
Degree, and more fiber number can be accommodated, thus realize jumbo transmission information.The outside of Loose tube 2 is arranged by phosphorus
Changing steel wire 3 and high-modulus Kev draws aramid fiber 4 to combine the reinforcement made, as a kind of embodiment, and phosphating steel wire 3 straight
Footpath uses 0.5mm, and the structure of such reinforcement is more stable, mechanical strength is higher, it is possible to digital preservation optical fiber is from stress shadow
Ringing or bear extremely low stress, effectively avoiding fibercuts to damage, effectively solve that single use reinforcement brings draws
Stretch the problem that intensity is not enough, meet the technology requirement of house wiring.External sheath layer 5, external sheath layer 5 are set in the outside of reinforcement
Using low smoke and low halogen soft PVC, its waterproof mildew resistance is excellent, and good bandability has good environmental protection flame retardant
Energy.In order to strengthen protection against the tide, block-water performance, between reinforcement and external sheath layer 5, set up water blocking tape layer, select two-sided non-woven fabrics to hinder
