Technical Field

The utility model relates to an armor optical cable technical field specifically is a special seamless single mode twin-core field operations armor optical cable of fire control.

Background

Armored optical cables have important applications in telecommunication optical fiber long-distance lines and primary and secondary trunk transmission. However, armored optical fibers usually contacted by a general network management are mostly used for connecting two optical fiber network devices used in a machine room building, armored optical cables are sometimes needed to be used in some fire-fighting devices, the armored optical cables used for fire-fighting are sometimes needed to be pulled in the using process, some existing armored optical cables mainly comprise structures such as an outer layer sheath, stainless steel armors and cable cores in the optical cables, the anti-pulling effect of the cables is not good, certain positions of the cables are likely to be broken in the pulling process, and therefore the seamless single-mode double-core field-operation armored optical cable special for fire-fighting is provided.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a not enough to prior art, the utility model provides a special seamless single mode twin-core field operations armor optical cable of fire control possesses to be equipped with the one deck tensile on the surface of armor optical cable and pulls out the structure, has improved the tensile advantage of pulling out the ability of optical cable, has solved the problem that proposes among the above-mentioned background art.

(II) technical scheme

The utility model provides a following technical scheme: the utility model provides a special seamless single mode twin-core field operations armor optical cable of fire control, includes the optical cable main part, the optical cable main part is including outer jacket, stainless steel armour, flexible filling layer and sinle silk, the outer jacket is located outmost, the stainless steel armour is located the inside of outer jacket, the flexible filling layer is located the inside of stainless steel armour, the fixed surface cover of optical cable main part is equipped with the spacing ring, be equipped with the reinforced pipe on the spacing ring, the inside grafting of reinforced pipe has the strengthening rib.

Furthermore, the surface of sinle silk is equipped with the sheath, the sheath is located the inside of flexible filling layer, through the effect of sheath, is convenient for further protect the surface of sinle silk, then through the effect of flexible filling layer, can carry out buffer protection to the sinle silk of its inside and the surface of sheath.

Furthermore, the quantity of spacing ring is a plurality of, and is a plurality of spacing ring evenly distributed is on the surface of optical cable main part, and the interval between two adjacent spacing rings is equal.

Furthermore, the depressed part has all been seted up around the spacing ring, strengthen the inside at the depressed part of pipe joint, through the setting of depressed part, be convenient for fix the side at the spacing ring with strengthening the pipe joint, and the junction of reinforcing pipe and depressed part is further fixed through the welded mode.

Compared with the prior art, the utility model provides a special seamless single mode twin-core field operations armor optical cable of fire control possesses following beneficial effect:

this special seamless single mode two-core field operations armor optical cable of fire control, surface through at the cable main part is equipped with the spacing ring, all be equipped with the reinforced pipe around the spacing ring, then be equipped with the strengthening rib in the inside of reinforced pipe, when this cable main part of pulling, a part pulling force can be undertaken to reinforced pipe and inside strengthening rib, make the power that cable main part self received less relatively, and then improved the anti-drawing ability of this cable main part, reinforced pipe and strengthening rib are located around the cable main part simultaneously, also can form protection one to the surface of cable main part when using.
