Abstract

The utility model relates to a sheath pipe for an optical cable, wherein, a sheath pipe body made of soft and flexible material is of a tube shape. The sheath pipe made of the flexible material presents a collapse thin shape, and is convenient to penetrate through a large pipe; when the optical cable penetrates through the sheath pipe, the sheath pipe can also be pulled off, thereby not only avoiding the effect on the construction of cable penetration, but also effectively penetrating through more cables by utilizing the internal diameter of the large pipe. The soft and flexible material is weaved into a net-shaped structure by compounding nylon 6 and polyester yarn and has higher tensile strength and wear resistance; the cable-through speed is quicker, and the cables can penetrate through a curved passage with curvature radius, thereby reducing the labor intensity and saving the construction time; the cable-through rate is higher, and more cables can penetrate through the large pipe with an equal aperture, thereby saving resources; and the pressure to raw oil resources can also be lightened through replacing the material.

Description

A kind of optical cable protecting casing

Technical field:

The utility model relates to a kind of communication cable sheath, especially a kind of protective casing of soft flexibility.

Background technology:

Optical cable protecting casing is not worn or damages as the term suggests be used for protecting optical cable, especially optical cable to wear cable when construction protection epidermis, influences optical cable serviceable life.The optical cable construction method generally is: pre-buried bassoon in the face of land, also be referred to as underground pipe, and then the protecting pipe number that can hold according to bassoon wears protecting pipe; When specifically laying optical cable, optical cable number as required passes protecting pipe with the optical cable traction.Existing communication cable sheath generally adopts tygon (PE) light wall pipe and tygon silicon core pipe, these two kinds of product main materials produce by tygon (PE), quality is harder, pulling strengrth is low, in the practice of construction process, can not fully use space in the bassoon, have a large amount of gaps, it is low to wear the cable rate; And produce the starting material of these two kinds of products, and polyvinyl resin cost height, it is bigger to be subjected to the crude oil price influence.Fig. 1 and Fig. 2 are existing bassoon 1, protecting pipe 2 and optical cable 3 triadic relations figure, when protecting pipe 2 passes bassoon 1, need to consider the gap surplus, otherwise protecting pipe 2 can't draw and passes bassoon 1; Moreover 2 of optical cable 3 and protecting pipes will be considered the gap surplus equally, otherwise it is big to wear the cable resistance, are difficult to construction.Because protecting pipe 2 is material such as hard polyethylene and makes with the cable protection epidermis, fusing point is low, and local easily frictional heating when wearing cable produces defectives such as epidermis wearing and tearing, damage.

Summary of the invention:

The purpose of this utility model is a kind of cable jacket of being made by soft compliant material of design.

Technical solutions of the utility model are achieved in that a kind of optical cable protecting casing, it is characterized in that the protecting pipe main body is that soft compliant material is made the cast shape.The protecting pipe of flexible material becomes the lack of filling power shape, conveniently passes bassoon, and when wearing optical cable, can be strutted again, does not influence and wears the cable construction, and can effectively utilize big bore to wear more optical cable number.

Described soft compliant material is by nylon 6 and the composite braided network management framework that forms of PE yarn.Nylon 6 and polyester have higher fusing point, and friction factor is littler, and optical cable is easier to be passed.

The cast shape of described protecting pipe can be sewn to together by two to three protecting pipes, forms a group, makes things convenient for the identification and the shunt of optical cable.

The cast shape of described protecting pipe is by nylon 6 and the composite braided netted cylinder structure that forms of PE yarn.Directly, have higher standardization, alleviate the technology of secondary processing by the woven cylinder structure that forms.

The utlity model has the characteristics of design uniqueness, reasonable in design, utilize the composite braided protecting pipe of nylon 6 and polyester, have higher pulling strengrth and wearing quality, it is more convenient to wear cable, and can pass the bend of small curvature radius, reduce labour intensity and save the engineering time; It is higher to wear the cable rate, and equal bassoon bore can pass more optical cable, saves resource; Replacement by material also can alleviate the pressure to crude resources.

Wherein

1-bassoon 2-protecting pipe 3-optical cable

Embodiment:

With reference to Fig. 3, a kind of optical cable protecting casing, its protecting pipe 2 main bodys are that soft compliant material is made the cast shape.This soft compliant material is by nylon 6 and the composite braided reticulate texture that forms of PE yarn, and wherein the cast shape of protecting pipe 2 is to be made by the soft flexible Web materials doubling of sheet to form.Make by the soft flexible Web materials doubling of sheet and to form protecting pipe 2, can be sewn into one group, in figure, two one group and three one group, discern when being convenient to wear cable, and multichannel is divided cable identification by many protecting pipes 2.Protecting pipe can also be by nylon 6 and the composite braided netted cylinder structure that forms of PE yarn except flaky material is made, and also promptly directly by the woven tubular structure that forms, can be sewn to together by two to three protecting pipes equally, forms a group.Perhaps protecting pipe 2 can to show differentiation, make things convenient for the identification and the shunt of optical cable with versicolor yarn braiding.

With reference to Fig. 4 and Fig. 5, flexible shroud pipe 2 penetrates the structure in the bassoon 1, because flexible shroud pipe 2 is not when penetrating optical cable, it is folding lack of filling power shape, is very easy to pass bassoon 1, and traction gets final product slightly, does not have difficulty of construction.

With reference to Fig. 6 and Fig. 7, when wearing the cable construction, optical cable 3 one ends are drawn in the protecting pipe 2, because flexible shroud pipe 2 is but that folding is the lack of filling power shape, so the bore of protecting pipe 2 is machinable bigger, optical cable 3 is easier to be passed after it is strutted, and the nylon material of protecting pipe 2 has certain lubricity, optical cable 3 is highly susceptible to passing, and the protecting pipe 2 of redundance is nature lack of filling power shape, do not account for bassoon 1 space, and slightly plus-pressure also can squeeze unnecessary protecting pipe 2 flatly, perhaps extends to naturally in the gap between the optical cable 3, makes that 3 on optical cable is very near reliably, very closely knit, on the bassoon 1 of equal bore and optical cable 3 times, adopt the cable rate of wearing of flexible shroud pipe 2 can more traditional hard protecting pipe many.

The flexible shroud pipe that this practicality provides also can use in original underground pipe and be installed with on the pipeline of hard protecting pipe and optical cable, utilize gap or redundant space in the bassoon, pass the flexible shroud pipe once more, and select suitable optical cable to penetrate wherein, also be that a kind of of existing hard protecting pipe replenishes, reach and save then resource and the quantities of stringing again.
