Abstract
The present utility model relates to a flexible spiral optical cable. The cable comprises an oversheath and an optical communication unit wrapped inside the oversheath, the cable is characterized in that the oversheath is a spiral coil shape. An intermediate diameter of a spiral coil of the spiral coil shape is larger than or equal to 10mm. The cable has the following beneficial effects, first, the optical cable is a spiral coil structure, the structure is simple, the length of the optical cable is elastic, the optical cable is capable of bending freely, the use is convenient and flexible, and optical fiber inside the cable will never be damaged; second, a cable-opening rope (wire) is arranged inside the cable, and the optical cable can be divided and connected conveniently; and third, the optical cable can be widely applied to fiber-to-the-desk and other occasions in which mobile terminal equipment needs to be moved frequently.
Description
Technical field
The utility model relates to a kind of flexible screw optical cable for the optical communication transmission, applicable to the occasion of fiber to the desk and the more frequent mobile terminal device of need.
Background technology
Occasion such as light wire jumper field in frequent mobile optical transmission terminal equipment, need cable length that certain retractility is arranged, main use is the jumper wire optical cable of single core/multicore at present, adopts aramid fiber as reinforcement, perhaps utilizes steel wire wrapped to strengthen the tensile strength of optical cable.Because existing optical cable retractility is not enough, in use often be subject to instantaneous large stretching and make in the cable optical fiber impaired, the optical cable of the wrapped armouring of steel wire not only structure is comparatively complicated, and can not realize that the flexible and difference of cable length uses.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in structure, cable length retractable and flexible spiral optical cable for the deficiency of above-mentioned prior art existence.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include oversheath and the optical communication element that is coated in the oversheath, it is characterized in that described oversheath is the helix round.
Press such scheme, described oversheath is equal diameter helix round.
Press such scheme, the spiral winding central diameter of described helix round is more than or equal to 10mm.
Press such scheme, described oversheath xsect is rectangular or circular.
Press such scheme, described oversheath inner chamber is installed on out hawser.
Press such scheme, described optical communication element is optical fiber, tight tube fiber or fibre ribbon.
Press such scheme, termination, described optical cable one or both ends is set to straight-line segment.
Press such scheme, described optical fiber or the tight tube fiber that is coated in the oversheath is 1 ~ 6.
The beneficial effects of the utility model are: 1, optical cable is helical coil structure, and is not only simple in structure, but and the cable length elastic telescopic, bending freely, easy to use and flexible, and can not damage optical fiber in the cable; 2, hawser (line) is opened in setting in the cable, is convenient to the optical cable difference and continues; 3, the utility model can be widely used in the occasion of the frequent mobile terminal devices of need such as fiber to the desk.
Description of drawings
Fig. 1 is the one-piece construction figure of an embodiment of the utility model.
Fig. 2 is the transverse cross-sectional view of an embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing, include oversheath 3, described oversheath xsect is rectangular, is 5mm * 4mm, and the oversheath intracavity section is also rectangular, be coated with 6 tight tube fibers 2 in the oversheath, and be installed on 1 and open hawser 1, described oversheath is equal diameter helix round, and spiral winding 4 central diameters of helix round are 12mm, be spaced apart 0 ~ 2mm between each spiral, termination, described optical cable two ends is set to straight-line segment 5.Present embodiment is extruded square-section oversheath optical cable by the screw extrusion mould, realizes good elastic telescopic and the bending of cable length.
