Abstract
The utility model discloses a stranded optical cable, which belongs to the technical field of optical cable production. The utility model has the technical points that: the stranded optical cable comprises a water-blocking tape and a cable core, wherein the cable core is arranged in the water-blocking tape and consists of a central reinforcing core, water-blocking yarns and a plurality of optical fiber bundles wound on the central reinforcing core; and the cable core is also provided with filling yarns which are arranged among the optical fiber bundles at intervals. The stranded optical cable provided by the utility model is stable in structure, tight in longitudinal wrap and attractive in appearance and is used for transmitting communication signals.
Description
Technical field
The utility model relates to a kind of optical cable, more particularly, relates in particular to a kind of layer-stranding cable.
Background technology
At present, a kind of layer-stranding cable is arranged, because requirement of client, cable core structure is more special: the stranded unit of 1 central reinforce member (0.5mmFRP)+3 2.0mm.Each unit size great disparity of cable core is bigger, and each stranded cell gap is too big, and cable core is rounding not, and the 0.5mmFRP quality is softer.In the cable core production run, FRP runs out of outside the cable core by the gap from the cable core center easily, thereby has influence on the transmission and the mechanical property of optical cable in sheath operation production run.In addition, because structural instability, the cable core twisting pitch is difficult to control, if pitch control is bad, will certainly have influence on the machinery and the environmental performance (temperature cycling test) of optical cable.Because this optical cable core external demand bag one deck waterstop is used for vertically blocking water, vertical bag rear surface is rounding not, and the waterstop bag do not live cable core, and block-water effect is also undesirable.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, and a kind of Stability Analysis of Structures, the vertical layer-stranding cable that wraps tight and good looking appearance are provided.
The technical solution of the utility model is achieved in that a kind of layer-stranding cable, comprise waterstop and be located at the interior cable core of waterstop, cable core is made of around the stranded fibre bundle of center strengthening core center strengthening core, water blocking yarn and some, wherein, also be provided with the filling yarn in the described cable core, fill yarn and be disposed between the fibre bundle.
In above-mentioned a kind of layer-stranding cable, described center strengthening core is the fibre-reinforced plastics of Φ 0.5mm.
In above-mentioned a kind of layer-stranding cable, described fibre bundle and fill yarn and be respectively three is spaced and stranded around the center strengthening core.
In above-mentioned a kind of layer-stranding cable, described fibre bundle is made of bag optical fiber in the beam tube.
In above-mentioned a kind of layer-stranding cable, described fibre bundle is made of bag optical fiber in the gasket for packing.
After the utility model adopts said structure, fill yarn by increasing between fibre bundle, the center strengthening core is difficult for from middle position displacement to cable core, the cable core structure of producing is stable, the tight and outward appearance rounding of vertical bag; Twisting pitch is stable and easy to control.Greatly reduce the disqualification rate of light transmission and machinery and environmental performance behind the finished product; And finished product outward appearance rounding is attractive in appearance, saves the material cost of sheath, has reduced the wasting of resources.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the another kind of embodiment of the utility model.
Among the figure: waterstop 1, cable core 2, center strengthening core 3, water blocking yarn 4, fibre bundle 5, filling yarn 6, beam tube 4a, optical fiber 4b, gasket for packing 4c.
Embodiment
Consult shown in Figure 1, a kind of layer-stranding cable of the present utility model, comprise waterstop 1 and the cable core 2 that is located in the waterstop 1, cable core 2 mainly by center strengthening core 3, water blocking yarn 4 and, three fibre bundles 5, three fill yarn 6 and constitute, filling yarn 6 is disposed between the fibre bundle 5 also stranded around center strengthening core 3 together, fill the gap in the yarn 6 effectively filling groups water band 1, make center strengthening core 3 be difficult for being moved to the outside from the center of cable core, center strengthening core 3 is the fibre-reinforced plastics of Φ 0.5mm, has characteristics such as light weight, intensity height; Fibre bundle 5 is made of bag optical fiber 4b in the beam tube 4a.
Consult shown in Figure 2, a kind of layer-stranding cable of the present utility model, its structure is basic identical with embodiment 1, difference is that fibre bundle 5 is to constitute by wrapping optical fiber 4b in the gasket for packing 4c.This structure has the advantage identical with embodiment 1.
Claims (5)
