Description
Technical field
The present invention relates to a kind of optical cable of the anti-unfirmly closing of protection against rodents.
Background technology
Now society, with the fast development of optical communications industry, cable manufactures are widely used, but circuit often because
A variety of causes is destroyed, and such as natural calamities such as earthquake, mud-rock flows, these are not that manpower can control, we do not discuss temporarily,
But in some areas, as northeast is meagrely-populated, mouse is various, and the plague of rats is serious, the south in south east asia and China, because gas
It is suitable to wait, and animal reproduction is very fast, and the plague of rats is also very serious.
Anti-mouse ant-proof optical cable in the market is existing several, 1, steel wire it is wrapped, but weight is big, and of high cost, optical cable is once old
Mouse is destroyed, and cannot can be used quickly in the place that rainfall is plentiful；2nd, filament winding bag is peeled off, shortcoming is, if after rat poison is bad, just not
It can reuse, cannot be used after being snapped；3rd, irritating additive is put into, allows mouse ant not like；Shortcoming be taste can with when
Between it is thin out, the protection against rodents time is shorter.
The content of the invention
The purpose of the present invention is to solve defect existing in the prior art, there is provided one kind can effective, long-term protection against rodents prevent
The optical cable of unfirmly closing.
In order to achieve the above object, the present invention provides a kind of compound light current rodent-resistant cable of photoelectricity, including optical cable inner core
And oversheath；Light current rodent-resistant cable of the present invention further includes inner sheath and conductive metal mesh；Inner sheath is arranged on optical cable inner core and outer shield
Between set；Conductive metal mesh is arranged between inner sheath and oversheath.
Inner sheath selects soft sheath material, such as PVC and PE materials.Oversheath selects conventional jacket material,
Such as PE materials.Conductive metal mesh uses uncorruptible material, such as stainless steel cloth or copper mesh.
Optical cable core arrangement can use various different desired structures, such as layer-twisted type, central tubular.
Further, conductive metal mesh grid assumes diamond in shape, and length of side 0.5-2cm, angle is 25-60 °.
Further, the thickness of inner sheath is 0.8-1.0cm；The thickness of oversheath is 1.5-3cm；Form conductive metal mesh
The diameter of wire be less than 0.2mm.
Present invention also offers the above-mentioned preparation method for stating light current rodent-resistant cable, comprise the following steps：
（1）Make optical cable inner core；
（2）Sheath shaping：Inner sheath is wrapped up in optical cable inner core periphery；
（3）Secondary sheath shaping：By more conductive wires successively by rotating forward cage and reversion cage to step（2）Once protect
Optical cable inner core after sleeve forming is wound, and conductive metal mesh is formed in inner sheath outer circumferential side, subsequently into oversheath extruder
Carry out outer oversheath extrusion molding.
Further, the rotating speed for rotating forward cage and reversion cage is 10-80rpm, and the extrusion molding of oversheath extruder is fast
Spend for 10-50m/min.
The present invention has the following advantages compared with prior art：
1st, the present invention is passed through light current, effectively to destroying the mouse of optical cable, bird carries out by setting conductive metal mesh after optical cable construction
Electric shock, prevents the further destruction of optical cable in time；Conductive wire uses net structure at the same time, even if certain one metal wire is snapped
It is disconnected, power effect will not be influenced.
2 at the same outer protective sleeve use duplex sheath form, when oversheath is destroyed, inner sheath also ensures that optical cable leads to
The normal operation of letter.
3rd, the present invention is automated, one-pass molding when carrying out conductive metal mesh and oversheath is molded using bipacking-auger,
Efficiency is improved, and ensure that the integrality of conductive metal mesh, preparation process is simple.

Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the compound light current rodent-resistant cable of photoelectricity of the present invention includes cable core, inner sheath 3, leads successively from the inside to the outside
Electric metal net 2, oversheath 1.Inner sheath 3 selects soft sheath material, such as PVC and PE materials, thickness 0.8-
1.0cm.Oversheath 1 selects conventional jacket material, such as PE materials, thickness 1.5-3cm.2 use of conductive metal mesh is not perishable
The material of erosion, such as stainless steel cloth or copper mesh, can select the material of metal mesh, group according to the soil environment of place to use
Wire diameter into metal mesh is advisable less than 0.2mm.Optical cable core arrangement can use various different desired structures, such as layer
Strand formula, central tubular etc..As shown in Figure 1, the optical cable inner core selected in the present embodiment includes metal reinforcement 6 and is stranded in metal
Multiple casings 4 of 6 outer circumferential side of reinforcer, the quantity of casing 4 and its quantity of internal optical fiber 5 are determined as requested.It is conductive
2 grid of metal mesh assumes diamond in shape, and length of side 0.5-2cm, angle is 25-60 °.
The preparation process of the light current rodent-resistant cable is as follows：
（1）As requested, optical cable inner core is made using conventional method；
（2）Sheath shaping：Inner sheath is wrapped up in optical cable inner core periphery using conventional method；
（3）Secondary sheath shaping：As shown in Fig. 2, by more conductive wires 10 successively by rotating forward cage 8 and reversion cage 9
To step（2）Optical cable inner core 7 after sheath shaping is wound, and forms conductive metal mesh in inner sheath outer circumferential side, then
Outer oversheath extrusion molding is carried out into oversheath extruder 11.In forming process, the rotating speed for rotating forward cage and reversion cage is
10-80rpm, the extrusion molding speed of oversheath extruder is 10-50m/min.
Light current is passed through after optical cable construction（Direct current is less than 36V, and exchange is less than 32V）, this voltage moves most of small-sized lactations
Thing has electric shock effect.When running into mouse（Or birds etc.）When destroying optical cable, teacher breaks by the teeth oversheath, when contacting conductive metal mesh,
It can be electrically shocked, so that abandon destroying, and light current will not have harm to people, even if mouse breaks by the teeth, oversheath electric leakage can not produce people
It is raw to influence, animal life will not be endangered.
