Abstract
An optical cable with corrugated metallic protection sheath is composed of bundle of optical fibrs, a corrugated metallic protection sheath, and a sleeve tube made of plastics. Its advantages are high torsion strength and high corrosion resistance.
Description
Technical field:
The present invention relates to a kind of optical element, particularly a kind of manufacturing of optical cable, especially a kind of optical cable with metal corrugated pipe protective sheath.
Background technology:
Can include one or more strands of light transmitting fibers in the boundling in the optical cable of prior art, these fibers are placed in the flexible anti sheath, usually the flexible anti sheath is made by tygon or Polyvinylchloride or other plastic materials, for strengthening the ability of the anti-tractive of optical cable, the someone proposes at rigid protection cover of the external increase of flexible anti sheath.
Summary of the invention:
Technical matters to be solved by this invention is: owing to can include one or more strands of light transmitting fibers in the boundling in the optical cable of prior art, these fibers are placed in the flexible anti sheath, usually the flexible anti sheath is made by tygon or Polyvinylchloride or other plastic materials, so the ability of anti-tractive is low, light transmitting fiber ruptures easily, cause communicating interrupt, for strengthening the ability of the anti-tractive of optical cable, someone proposes at rigid protection cover of the external increase of flexible anti sheath, but optical cable is when distortion, the rigid protection cover breaks easily, causes the permanent damage of optical cable.The technical scheme that the present invention is adopted for solution above-mentioned technical matters of the prior art provides a kind of optical cable with metal corrugated pipe protective sheath, described this optical cable with metal corrugated pipe protective sheath comprises a flexible anti sheath and the rigid protection cover in the prior art, wherein, be provided with the optical fiber boundling in the described flexible anti sheath, described optical fiber boundling includes one above optical fiber, described rigid protection is set on the excircle of described flexible anti sheath, described rigid protection cover adopts metal material to make, preferred metallic aluminium or the zinc of adopting, described rigid protection cover is metallic bellows, the cross section that described rigid protection is enclosed within on the length direction of optical cable is corrugated, arranged outside at described rigid protection cover has a sleeve pipe, and sleeve pipe adopts the plastics manufacturing.The present invention and prior art contrast, because be provided with the rigid protection cover that constitutes by metallic bellows on the excircle of the flexible anti sheath in prior art, so can improve the anti-twist ability of optical cable greatly, simultaneously, because the outside at described rigid protection cover is provided with plastic casing again, so can make the rigid protection cover that constitutes by metal material avoid corrosion.
Description of drawings:
Fig. 1 is a kind of synoptic diagram with optical cable of metal corrugated pipe protective sheath of the present invention.
Embodiment:
As shown in Figure 1, a kind of optical cable of the present invention with metal corrugated pipe protective sheath, comprise a flexible anti sheath 1 and the rigid protection cover 2 in the prior art, wherein, be provided with optical fiber boundling 3 in the described flexible anti sheath 1, described optical fiber boundling 3 includes one above optical fiber, described rigid protection cover 2 is arranged on the excircle of described flexible anti sheath 1, described rigid protection cover 2 adopts metal material to make, in a preferred embodiment of the invention, rigid protection cover 2 adopts Zinc material to make, described rigid protection cover 2 is a metallic bellows, the cross section of described rigid protection cover 2 on the length direction of optical cable is corrugated, in the arranged outside of described rigid protection cover 2 sleeve pipe 4 arranged, and sleeve pipe 4 adopts the Polyvinylchloride manufacturings.
Claims (2)
1, a kind of optical cable with metal corrugated pipe protective sheath, comprise one in the prior art the flexible anti sheath and the rigid protection cover in prior art, it is characterized in that: be provided with the optical fiber boundling in the described flexible anti sheath, described optical fiber boundling includes one above optical fiber, described rigid protection is set on the excircle of described flexible anti sheath, described rigid protection cover adopts metal material to make, described rigid protection cover is metallic bellows, the cross section that described rigid protection is enclosed within on the length direction of optical cable is corrugated, in the arranged outside of described rigid protection cover a sleeve pipe is arranged.
