Description

A kind of high intensity armouring field optical cable

Technical field

Field optical cable is the utility model is related to, more particularly to a kind of high intensity armouring field optical cable.

Background technology

High intensity armouring field optical cable is mainly used in wild environment, instead of traditional outdoor optical cable, volume is big, construction The shortcomings that complicated, environmental suitability difference, there is small high tensile strength, resistance to side pressure, external diameter, in light weight, good environmental adaptability, quick Lay and repeatedly folding and unfolding the characteristics of, the extensive use in emergency communication, emergency dealing, field construction.Laid in above-mentioned environment When, in time, effectively establishing stabilized communication has striven for the quality time.The laying environment of high intensity armored type field optical cable can be present Stone or surface car roll, and great side pressure are caused to optical cable, while complicated wild environment can also be made to optical cable The corrosion of acid-forming base salt.Existing high intensity armouring field optical cable generally use is directly in the wrapped nonmetallic reinforcement in the outside of optical fiber The mode of material or wrapped steel band increases lateral pressure resistant ability as enhancement layer, and its tensile strength is low, lateral pressure resistant poor performance, optical cable Larger resistance during being pulled when middle field is laid be present and be easy to be suspended to sharp objects makes optical cable moment by larger drawing Power, next conventional cable bear rolling on optical cable in incessantly larger lateral pressure especially vehicle tyre or crawler belt, cause to strengthen Layer rupture, subsequent optical fiber is exposed from breaking point, causes fibre loss therein to increase, be even broken, makes whole optical communication system Failure.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of high intensity armouring field optical cable, the optical cable have compared with Big tensile strength, and side pressure or radial pressure can be resisted, avoid optical fibre damage.

To achieve the above object, the utility model provides following technical scheme：A kind of high intensity armouring field optical cable, bag Loose tube is included, bend insensitive fiber is provided with the Loose tube, the bend insensitive fiber is provided with 1~12, the pine Be filled with material water-proof material in sleeve pipe, process layer of steel wire on the outside of Loose tube, steel wire is covered in the outside composition armor of Loose tube, The steel wire twist twists has extruded one layer of sheath in the outside of Loose tube, the armor outer layer.

Preferably, material water-proof material uses greasy for preventing water or the yarn that blocks water.

Preferably, the external diameter of Loose tube is 1.0~Ф of Ф 2.4mm.

Preferably, the steel wire of armor uses mild steel wire or bullet wire, high-carbon steel wire.

Preferably, sheath is made of flame retardant polyurethane or halogen-free anti-flaming polyolefin class material.

Preferably, Loose tube is made of stainless steel material.

Using above-mentioned technical proposal, the utility model compared with prior art, has the advantages that：1. with good Structure design and metal armouring technique, the use of high-tensile steel wires, optical cable is also had in addition to excellent transmission performance There is good tensile strength；2. there is excellent lateral pressure resistant performance, rigid structure of the optical fiber by spiral armor steel wire Protection, when by side pressure or grinding pressure, can make lateral pressure along rigid structure body be distributed and conduct in the shape of a spiral to ground or its Its object, effectively improve the side pressure tolerance of optical cable；3. have excellent decay resistance, solve in the wild and harsh and unforgiving environments Under, the requirement of quickly retracting, Reusability, while this product also has external diameter small, in light weight, loss is small, and electromagnetism interference is strong The features such as.

Brief description of the drawings

Fig. 1 is the cable configuration schematic diagram of the utility model background technology；

Fig. 2 is structural representation of the present utility model.

Embodiment

Below in conjunction with the accompanying drawings, by the description to embodiment, the utility model is described further：

As shown in Fig. 2 a kind of high intensity armouring field optical cable of the utility model, including Loose tube 1, Loose tube 1 are external diameter For 1.0~Ф of Ф 2.4mm stainless steel tube, Loose tube 1 is interior to be provided with bend insensitive fiber 2, and bend insensitive fiber 2 is provided with 1 ~12, Loose tube 1 is interior to be filled with material water-proof material 3, and material water-proof material 3 uses greasy for preventing water or the yarn that blocks water.The outside of Loose tube 1 twists Layer of steel wire processed, the outside that steel wire is covered in Loose tube 1 form armor 4, and steel wire is twist twisted in the outside of Loose tube 1, The outer layer of armor 4 has extruded one layer of sheath 5, and steel wire can use mild steel wire or bullet wire, high-carbon steel wire, such steel wire tool There is the characteristics of high intensity, be advantageous to protect Loose tube 1.Sheath 5 uses flame retardant polyurethane or halogen-free anti-flaming polyolefin class material system Into cost-effective.

The utility model twists outside Loose tube 1 armor 4, and armor is twist distributed in outside Loose tube 1, When Loose tube 1 bears side pressure or radial pressure, pressure can be conducted along steel wire, the conduction orientation of pressure is also helically Shape, so as to protect the bend insensitive fiber 2 inside Loose tube 1 without prejudice, it ensure that the unimpeded of optic communication.

Reference in Fig. 1 of the present utility model is respectively that 1a is optical fiber, and reinforcer centered on 2a, 3a is enhancement layer, 4a is sheath.

Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to In the scope of protection of the utility model.
