Description

A kind of anti-animal bites optical cable

Technical field

The utility model is related to the technical field of structure optical cable, and especially a kind of anti-animal bites optical cable.

Background technology

Some specific regions of optical fiber cable for direct burial and duct optical cable, are frequently subjected to biting of rodent and sting, to optical cable at present Design and maintenance bring very burden.It is from structure or material that optical cable manufacturer bites the Design Countermeasure stung to rodent Improve so as to have the function of preventing animal from biting.In prior art, more common two methods are to add in protective cover material Pungent agent and use multiple sheath armouring.

The first adds the anti-animal of pungent agent and bites method, be mediate in mass, add in the production process of granulation peppery Taste agent, this kind of mode can produce pungent smell in squeeze jacket production process, have impact on the healthy of operating personnel, and It is necessary that using protective gloves in work progress, preventing hand directly contact optical cable from having burning heat sensation, and pungent agent makes for a long time With migrating from protective cover material in environment and volatilizing, thus it is difficult to keep long-term effective time；Second method is to use multilayer The double-deck steel-tape armouring of armouring, such as GYTS53, after the wire armoring of GYTS333, cable outer diameter is big, in quality, not flexible, Manufacture difficulty is high and is difficult to construct.

Utility model content

The purpose of this utility model is the problems referred to above existing for existing technology, there is provided a kind of anti-animal bites light Cable, the utility model device solves the problems, such as that optical cable is bitten by animal, and cable outer diameter reduces, quality lightens, not flexible, appearance Easily manufacture and easy construction.

For this reason, the technical solution that the utility model is taken is：

A kind of anti-animal bites optical cable, including Fiber glass rod, optical cable, gasket for packing, ground floor nylon outer sheath, cable core resistance Water thing, armor steel wire, waterstop, steel band, second layer nylon outer sheath, are provided with least one optical cable and fill out outside Fiber glass rod Fill rope, be filled with cable core water-blocking material between Fiber glass rod, optical cable and gasket for packing gap, outside cable core water-blocking material, be enclosed with ground floor Nylon outer sheath, is laid with armor steel wire, is enclosed with waterstop, waterstop outside armor steel wire outside ground floor nylon outer sheath Outside is enclosed with steel band, is enclosed with second layer nylon outer sheath outside steel band.

As further preferred, described armor steel wire diameter is 0.1mm ~ 1mm.

As further preferred, described armor steel wire is that spiral is stranded to be laid on described ground floor nylon outer sheath.

The having the beneficial effects that of technique scheme：

1st, the utility model optical cable center adopts Fiber glass rod as support, rather than adopts metal wire, can be effective Reduce the weight of optical cable；

2nd, the utility model optical cable adopts double-decker, i.e. ground floor nylon outer sheath and second layer nylon outer sheath, by force Degree is higher, and no any peculiar smell, prevents ant from biting better performances；

3rd, it is laid with armor steel wire outside the utility model optical cable ground floor nylon outer sheath, optic cable diameter and fall can be reduced Low weight, according to the higher stainless steel wire of intensity, not only can prevent larger animal break by the teeth the structure beyond steel wire when, and Stainless steel wire will not be because of moisture corrosion, and armor steel wire lays using spiral is stranded, can prevent animal from biting further；

4th, the utility model Water-blocking tapes for fiber optic cable is wrapped with steel band, equally can keep out the corrosion of moisture, and the effect of steel band is Prevent general toy from optical cable is destroyed, for example the toy such as mouse, woodpecker；

5th, the utility model optical cable is provided with space due between armor steel wire, for longitudinal water-blocking, armor steel wire and steel band Between be provided with waterstop, waterstop is hydrolyzed into pasty masses after meeting water, and is expanded to each space, reaches the purpose blocking water.

Brief description

Fig. 1 is that anti-animal of the present utility model bites the structural representation of optical cable.

In figure：1st, Fiber glass rod；2nd, optical cable；3rd, gasket for packing；4th, ground floor nylon outer sheath；5th, cable core water-blocking material；6、 Armor steel wire；7th, waterstop；8th, steel band；9th, second layer nylon outer sheath.

Specific embodiment

For making feature of the present utility model and advantage clearer, it is described with reference to specific embodiment.

The optical cable as shown in figure 1, a kind of anti-animal bites, including Fiber glass rod 1, optical cable 2, gasket for packing 3, ground floor nylon Oversheath 4, cable core water-blocking material 5, armor steel wire 6, waterstop 7, steel band 8, second layer nylon outer sheath 9, outside Fiber glass rod 1 It is provided with least one optical cable 2 and gasket for packing 3, between Fiber glass rod 1, optical cable 2 and gasket for packing 3 gap, be filled with cable core water-blocking material 5, It is enclosed with ground floor nylon outer sheath 4 outside cable core water-blocking material 5, outside ground floor nylon outer sheath 4, be laid with armor steel wire 6, It is enclosed with waterstop 7 outside armor steel wire 6, be enclosed with steel band 8 outside waterstop 7, be enclosed with outside steel band 8 outside second layer nylon Sheath 9.

In the present embodiment, a diameter of 0.1mm ~ 1mm of described armor steel wire 6, armor steel wire 6 is the higher stainless steel of intensity Silk, can mitigate anti-animal and bite the diameter of optical cable and weight, be also possible to prevent larger animal simultaneously and break by the teeth the waterstop of optical cable 7th, when steel band 8, second layer nylon outer sheath 9, will not be because of moisture corrosion.

In the present embodiment, described armor steel wire 6 is that spiral is stranded to be laid on described ground floor nylon outer sheath 4, permissible Effectively prevent animal anti-animal is bitten optical cable from biting, the such as animal such as squirrel, wild boar, bear.

Production procedure, after Fiber glass rod 1, optical cable 2, gasket for packing 3 are stranded, fills cable core water-blocking material 5, wraps up ground floor Nylon outer sheath 4, lays armor steel wire 6 ground floor nylon outer sheath 4 external spiral is stranded, then parcel waterstop 7, steel band successively 8th, second layer nylon outer sheath 9, detects qualified rear stranding.

In addition to the implementation, the utility model can also have other embodiment.All employing equivalents or equivalent change Change the technical scheme of formation, all fall within protection domain of the present utility model.
