A kind of light-duty anti-unfirmly closing aerial optical cable is disclosed in the present embodiment, including cable core 1,1 periphery of the cable core cladding
There is stainless steel wire mesh 2,2 periphery of stainless steel wire mesh is coated with oversheath 3.
The stainless steel wire mesh 2 includes：First stratum reticulare 201, the second stratum reticulare 202, third stratum reticulare 203, first net
Layer 201 and the thickness that the third stratum reticulare 203 is stainless steel cored yarn layer, first stratum reticulare 201 and the third stratum reticulare 203
Spend equal, the thickness of 201 and second stratum reticulare 203 of the first stratum reticulare is 0.5-1.5mm.
The network of first stratum reticulare 201 and the third stratum reticulare 203 is different, the latitude of first stratum reticulare 201
The distance between yarn is that the distance between a, the warp thread of first stratum reticulare 201 is b, with the weft yarn of the third stratum reticulare 203 it
Between distance be the distance between a, the warp thread of the third stratum reticulare 203 be b, the b<a.In the present embodiment, stainless ladle
Spacing between the warp thread and weft yarn of heart yarn layer is unequal, and spacing and the angle α of warp thread and weft yarn influence each other, and are tested by experiment
Card, a 3-5mm, b 1-2mm, when α is 0-90 °, flexibility, shielding properties and the mechanical property of stainless steel wire mesh
Preferably.
In the present embodiment, a is 3-5mm, b 1-2mm, the weft yarn of first stratum reticulare 201 and the third net
Angle between the weft yarn of layer 203 is α, and the α is 0-90 °.
It is detected by reflectance factor, when the α is 0-45 °, the reflectance factor of the stainless steel wire mesh is gradually reduced, institute
State α for 45-90 ° when, the reflectance factor of the stainless steel wire mesh gradually increases.When α is 45 °, reflectance factor is minimum, that is, shields
Covering that performance is worst, reflectance factor when at 0 ° with 90 ° is consistent, individually for the shielding properties of stainless steel wire mesh, the first net
Alignment is consistent with rotation between layer and third stratum reticulare, but when α is 0-90 °, the soft bending property of stainless steel wire mesh increases
By force, therefore, the shielding properties of the stainless steel wire mesh of the utility model and soft bending property are preferable.
Second stratum reticulare 202 is blended yarn layer, and first stratum reticulare 201 is arranged on described second with third stratum reticulare 203

The Grid Align of layer 202 and the third stratum reticulare 203.
Above-mentioned stainless steel wire mesh uses three-decker, the first stratum reticulare and third stratum reticulare as stainless steel cored yarn layer, and second
Stratum reticulare is blended yarn layer, and the outer longitudinal wrap of cable core or wrapped stainless steel metal guipure and polyethylene outer sheath, such optical cable not only have
There are good flexibility and bendability etc., and the light-weight outer diameter of optical cable is small, and can effectively prevent birds and favore with and peck.
As shown in figure 5, the angle between the weft yarn and warp thread of first stratum reticulare 201 is β, the β is 30-90 °.And
And first stratum reticulare is contacted with the external sheath layer.By detection, there is netted lines on metal mesh belt surface in the present embodiment,
Production, which extrudes the sheath material melted during oversheath, can be embedded in metal mesh gap, oversheath can be made preferably to coat, and bond more
Closely, be not in bond the loosely bad phenomenons such as easy, cracking；The close structure between oversheath, the impermeable (ordinary steel belts in longitudinal direction
Armouring lap-joint easily seeps water)；Reticular zone has elasticity, with shock resistance, can there is the function of certain anti-air gun shot；Netted material
Material more saves metal material than traditional steel band or wire armoring, economizes on resources；Reduce product material cost, outer diameter is more
Small, weight, which is gentlier constructed, transports more convenient, aerial laying of being more convenient for.
Weft yarn and warp thread are orthogonal in the first stratum reticulare 201 in comparative example, when the first stratum reticulare is contacted with oversheath, oversheath
Covering property than the difference in the present embodiment.
In the present embodiment, the distance between 202 weft yarn of the second stratum reticulare and warp thread are equal.Second stratum reticulare 202
The distance between weft yarn and warp thread are 0.5-1mm.
In the present embodiment, by the line space design of 202 weft yarn of the second grenadine layer and warp thread into less than the first stratum reticulare 201 and
Three stratum reticulares 203, the flexibility of stainless steel wire mesh, shielding properties and mechanical property are preferable.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the utility model, the utility model
Protection domain it is without being limited thereto.The equivalent substitute or change that those skilled in the art are made on the basis of the utility model
It changes, is within the protection scope of the utility model.The scope of protection of the utility model is subject to claims.
