Problems solved by technology

[0003] Optical fiber cables are the main materials used in communication cables at present. Among them, optical fibers with armored structures have important applications in telecommunication optical fiber long-distance lines and primary and secondary trunk line transmissions. However, the current armored structures or optical fibers with armored structures It is inconvenient to strip the optical cable, especially during daily installation, use or maintenance. The inconvenience of stripping will lead to a decrease in installation or maintenance efficiency

Embodiment 1

[0036] like figure 1 As shown, the present invention provides a composite armor structure, comprising a steel base strip 1, wherein one side of the steel base strip 1 has a composite structure 2, the composite structure 2 is convenient to install or connect with the outer sheath layer 3 of the optical fiber cable; In another preferred embodiment of the present invention, the other side of the steel base tape 1 has the same composite structure 2 for easy installation or connection with the filling layer 41 of the optical fiber tube core 4 or the inner sheath layer 5 .

[0037] The composite structure 2 includes a first layer of film 21, a second layer of film 22 and a third layer of film 33, wherein the first layer of film 21 and the steel base belt 1 are bonded by electromagnetic compounding, and the electromagnetic compounding is an electromagnetic heating system. A heating method from the inside to the outside. When heating the substrate, the heating source will not directly...

Embodiment 2

[0043] like figure 2 As shown, the present invention provides a kind of optical fiber cable, has the composite armor structure in embodiment 1, wherein, the composite armor structure is sleeved in the outer sheath layer 3, and the inner layer of the composite armor structure is sleeved with an optical fiber tube Core 4, the outer layer of the optical fiber tube core 4 is sleeved with a filling layer 41, in this embodiment, the filling layer 41 is between the optical fiber tube core 4 and the steel base tape 1 of the composite armor structure (the steel base tape 1 has only one side When there is a composite structure 2), or the filling layer 41 is between the fiber tube core 4 and the third layer of film 23 of the composite armor structure (when both sides of the steel base tape 1 have a symmetrical composite structure 2), the fiber tube protection of the core, while the peeling strength of the second layer of film 22 and the third layer of film 23 of the composite structure ...

Embodiment 3

[0046] The composite armor structure in Example 1 is used to make the pole plate of lithium battery or hydrogen battery. When it is applied to lithium battery, due to the metal characteristics of polymer material and base material, when the metal base material is immersed in acidic solution, the metal base material The material will generate positive ions. Since the composite material is a multi-layer polymer material, a negative polarity is formed, and a closed electric field is generated between the metal base material and the polymer material, forming a new type of polar battery structure. This material ( Composite armored structure) is used as a battery multi-level board, which has the characteristics of small size, simple structure, multiple groups can be used in parallel, and long service life.

[0047] The peeling strength of the second layer of film 22 and the third layer of film 23 of the composite armor structure of the present invention is relatively stable, convenie...

Abstract

The invention discloses a composite armoring structure and an optical fiber cable, and the structure comprises a steel base band, and one surface of the steel base band is provided with a composite structure. The composite structure comprises a first film layer, a second film layer and a third film layer, and the first film layer and the steel base band are bonded through electromagnetic compounding; the second-layer film is made of polyethylene; the third-layer film is made of modified polypropylene; the steel base band is made of low-carbon steel, and the thickness of the steel base band ranges from 0.1 mm to 0.3 mm; the outer surface of the steel base band is provided with a chromium-plated textured layer; the first layer of film is made of a propylene copolymer. The stripping strength of the second layer film and the third layer film is relatively stable, stripping is convenient, the third layer film and the outer sheath layer of the optical cable can be firmly bonded, and the optical cable can be used for stripping the outer sheath layer and an armored structure (without the third layer film) during installation or maintenance, so that the installation and use efficiency is improved; and the head of the optical cable can be conveniently used, and separation and connection (or installation) are facilitated.

Description

technical field [0001] The invention relates to an armored structure for an optical fiber cable, in particular to a composite armored structure and an optical fiber cable. Background technique [0002] A fiber optic cable is a communication cable consisting of two or more glass or plastic optical fiber cores within a protective cladding covered by a plastic PVC outer sleeve. Signal transmission along the internal fiber optics typically uses infrared light. [0003] Optical fiber cables are currently the main materials used in communication cables. Among them, optical fibers with armored structures have important applications in long-distance telecommunication optical fiber lines and primary and secondary trunk line transmission. However, the current armored structures or optical fibers with armored structures It is inconvenient to strip the optical cable, especially during daily installation, use or maintenance. The inconvenient stripping will lead to a decrease in installa...
