Abstract
The utility model discloses a high-strength tensile communication cable, comprising wire pair cables, an insulating inner sheath, and an outer sheath. Outside of the wire pair cables is wrapped with the insulating inner sheath, and outside of the insulating inner sheath is wrapped with an armoured shielding layer. Outside of the armoured shielding layer is wrapped with the outer sheath. A plurality of reinforcing ribs which are parallel with a cable core are disposed between the armoured shielding layer and the outer sheath. In the communication cable, the armoured shielding layer and the reinforcing ribs are disposed between the insulating inner sheath and the outer sheath, thereby improving longitudinal tensile strength of the communication cable, making the communication cable withstand frequent pulling and bending, so that service life of the communication cable is prolonged.
Description
Technical field
The utility model relates to a kind of telecommunication cable, specifically relates to a kind of high strength tension telecommunication cable.
Background technology
At present, the telecommunication cable that in colliery gallery, inclined gallery and in the constructing tunnel, is provided with, usually by more frequent laying, pulling, bending with turn round and draw, therefore cause the life-span of cable not long, often fracture easily, thereby cause cable short circuit, cause that unnecessary accident takes place, therefore need have stronger tensile strength at these local telecommunication cables that use.The existing telecommunication cable that uses in the colliery and in the constructing tunnel, its structure is generally: comprise the copper cash core at the center of being arranged on, coat polyethylene layer outside the copper cash core, coat the polyvinyl chloride insulation sheath outside polyethylene layer.The cable of this structure, though transmission performance and insulation property are better, the tension dynamics is not enough, and useful life is short, and signal is subject to external magnetic field and disturbs, and the antijamming capability of transmission signals is poor.
The utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of high strength tension telecommunication cable is provided, to improve the tensile strength of telecommunication cable, prolonging the useful life of telecommunication cable.
To achieve these goals, the technical solution adopted in the utility model is: a kind of high strength tension telecommunication cable, comprise that line is to cable, insulation inner sheath and oversheath, described line is coated with the insulation inner sheath to cable, be coated with the armouring screen at the insulation inner sheath, be coated with oversheath at the armouring screen; Between described armouring screen and oversheath, be provided with the some reinforcements parallel with cable core.
Preferably, described reinforcement is a steel wire.
Adopt the utility model of the technical program, its beneficial effect is: telecommunication cable of the present utility model, between insulation inner sheath and oversheath, be provided with armouring screen and the some reinforcements parallel with cable core, reinforcement the endwise tensile strength that has strengthened telecommunication cable is set, make telecommunication cable can tolerate frequent pulling and bending, prolonged the useful life of telecommunication cable; The setting of armouring screen has not only improved the antijamming capability of telecommunication cable transmission signals, and strengthened the mechanical strength of telecommunication cable, improved the anti-erosiveness of telecommunication cable, in the higher colliery gallery of mechanical damage degree, inclined gallery and in the constructing tunnel, can directly lay this telecommunication cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, line is to cable; 2, insulation inner sheath; 3, armouring screen; 4, oversheath; 31, reinforcement.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, high strength tension telecommunication cable of the present utility model comprises line to cable 1, insulation inner sheath 2 and oversheath 4, and described line is coated with insulation inner sheath 2 to cable 1, be coated with armouring screen 3 at insulation inner sheath 2, be coated with oversheath 4 at armouring screen 3; Between described armouring screen 3 and oversheath 4, be provided with the some reinforcements parallel 31 with cable core.Described reinforcement 31 is a steel wire.
In use, because telecommunication cable of the present utility model is provided with armouring screen 3 and reinforcement 31 between its insulation inner sheath 2 and oversheath 4, therefore strengthened the endwise tensile strength of telecommunication cable, make telecommunication cable can tolerate frequent pulling and bending, prolonged the useful life of telecommunication cable; The setting of armouring screen 3 has not only improved the antijamming capability of telecommunication cable transmission signals, and strengthened the mechanical strength of telecommunication cable, improved the anti-erosiveness of telecommunication cable, in the higher colliery gallery of mechanical damage degree, inclined gallery and in the constructing tunnel, can directly lay this telecommunication cable.
Above-mentioned only is a kind of embodiment of the present utility model; not in order to restriction the utility model; those skilled in the art can make various changes and modifications to said structure; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
Claims (2)
1. a high strength tension telecommunication cable comprises line to cable, insulation inner sheath and oversheath, and it is characterized in that: described line is coated with the insulation inner sheath to cable, is coated with the armouring screen at the insulation inner sheath, is coated with oversheath at the armouring screen; Between described armouring screen and oversheath, be provided with the some reinforcements parallel with cable core.
