Abstract

The utility model belongs to the field of novel communication optical cables, specifically, discloses a composite optical cable. A cable core of the optical cable is composed of an optical fiber and a protective layer sleeved outside the optical fiber. The protective layer tightly covers the optical fiber, so, the optical cable is free from being filled with a cable compound, and various troubles caused by use of the cable compound in the prior art are avoided; additionally, two sides of the cable core are provided with conductor lines, which are excellent in tolerance and impact resistance to the pressure in any direction, and are beneficial for protecting the cable core.

Description

A kind of composite cable

Technical field

The utility model relates to the communications optical cable field, specifically refers to a kind of composite cable.

Background technology

Optical cable is as the carrier of optical fiber communication, distinguishes by its structure, can be divided into central beam tube type, layer-twisted type, skeleton etc., and it is widely used in the communication of industries such as post and telecommunications, telecommunications, railway, military affairs, satellite, broadcasting and TV.For common resident family, except the optical cable that inserts, also have telephone line, household electricity circuit, so just produced the problem of multi-thread house lead in.The loose nested structure that common outdoor optical cable uses; No matter tubular sheath is rigid plastics or protection metal pipe, all exist the hard characteristics of sleeve structure, though the hard protection that helps self; The lateral pressure resistant aspect is had certain effect, but the performance of anti-bending strength extremely is short of.For example when adopting metal tube, when very likely under the little bending radius in school, constructing, cause the pipe cracking or fracture, influence the communication of fiber waveguide; And loose nested structure; Between tubular sheath and fiber waveguide, paste certainly will will be packed into, and the greatest drawback of paste is not suit in indoor use, because paste is liquid; In certain temperature range, have bigger mobile influenced by ambient temperature big; And be difficult for hitting and remove, in addition, also extremely inconvenient to the welding construction.If, do not fill, then can't guarantee its permeability performance again, in case there is pressure differential, cable cream just possibly flow when reaching uniform temperature, and this kind optical cable protection also be short of to the lateral pressure resistant of optical fiber, thereby influence is communicated by letter.

The utility model content

The utility model purpose is to solve the deficiency of existing optical cable said structure, and a kind of simple in structure, composite cable that the lateral pressure resistant bending effect is good is provided.

The utility model composite cable; Comprise cable core, lay respectively at the cable core both sides the conductor lines with electric conductivity, parcel said cable core and conductor lines (rubber; Said cable core also comprises optical fiber and is nested with the protective layer outside optical fiber; Wherein said protective layer is wrapped in optical fiber closely, and the material of said protective layer is any one in PVC or polyester material or the nylon, the centre of said cable core between at least one pair of conductor lines.

Preferably, said conductor lines is any one in copper conductor wire rod or the aluminium conductor wire rod.

Further, be coated with the layer of protecting lacquer on described copper conductor wire rod or the aluminium conductor wire rod.

The diameter of the said conductor lines that is wrapped in rubber is greater than the said cable core that is wrapped in rubber.

The beneficial effect of the utility model composite optical cable is: the cable core of said optical cable is made up of optical fiber and the protective layer that is nested with outside optical fiber; Because of protective layer is wrapped in optical fiber closely; And need not to fill by cable cream, avoided the various troubles of prior art because of using cable cream to cause; The both sides of said cable core are provided with conductor lines in addition, no matter to the pressure from which direction, all have good tolerance and anti-impact force, help protecting cable core.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Be to be understood that practical implementation instance described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Ginseng Fig. 1, shown in Figure 2; Embodiment for the utility model composite cable; Said cable core 10 comprises protective layer 102 and optical fiber 101, and optical fiber 101 is closely wrapped up by protective layer 102, and the material of protective layer 102 is PVC or one of nylon or polyester material; Directly tightly be enclosed within outside the optical fiber 101 with one deck or two layers or multilayer ground; Inclined to one side because of optical fiber 101 diameters own, apply shearing force above that so be provided with the weight that can reach opposing optical fiber I01 behind the protective layer 102 fully outside, overcome the residual stress of optical fiber 101.Optical fiber 101 can have one or two or many.The side arrangement of said cable core 10 has at least one pair of exposed material to can be any one lead in copper conductor wire rod or the aluminium conductor wire rod as conductor lines 20.The size of the sectional area of conductor lines 20 is different according to purposes, but the diameter of said on the whole conductor lines 20 should in order to distinguishing and protection cable core 10, also be beneficial to the external shock power of eliminating side greater than the diameter of cable core 10; Said cable core 10 and the conductor lines 20 outer rubber 30 that together coat; Rubber 30 adopts has fire-retardant polythene material, thereby whole optical cable forms the offset flat shape global shape, when applying certain pressure above that; Can not exert all one's strength affacts on the cable core 10, can protect optical fiber 101 effectively.In addition, optical fiber 10 is tight tube structure, and optical fiber 101, protective sleeve 102 itself can bear certain strain, the centre of said cable core 10 between at least one pair of conductor lines 20, bending property and lateral pressure resistant performance in the time of therefore satisfying installation fully and lay.

In addition, in order to prolong the useful life of the utility model, be coated with layer of protecting lacquer 201 on the described copper conductor wire rod of said conductor lines 20 or the aluminium conductor wire rod.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
