In order to achieve the purpose, the technical scheme of the invention is realized as follows:

the utility model provides a wiring optical cable of many defence functions, includes the optical fiber core to and the outside of optical fiber core from inside to outside in proper order the cladding fibre yarn that blocks water, armor, ceramic fiber area, inner sheath and oversheath.

Furthermore, the thickness of each sheath layer coated on the outer side of the optical fiber core is uniform.

Further, the armor layer is a threaded armor pipe.

Furthermore, the armor layer is formed by lapping stainless steel bands with the compression capacity of 5000N/100 mm.

Furthermore, a rat bite preventing capsaicin is arranged between the inner sheath and the outer sheath.

Further, the outer sheath is a nylon sheath.

Further, the inner sheath is a PE sheath.

Compared with the prior art, the invention has the following advantages:

the invention has the advantages of simple structure, long service life, rat bite prevention, ant prevention, lightning protection performance, wide application range, simple operation, suitability for laying and using under various severe conditions, no need of reworking after laying and high use reliability of products, and can be used in any indoor and outdoor scenes.

Detailed Description

It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings, which are merely for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following examples.

A multi-prevention-function wiring optical cable is shown in figure 1 and comprises an optical fiber core 1, and a fiber water-blocking yarn 2, an armor layer 3, a ceramic fiber tape 4, an inner sheath 5 and an outer sheath 6 which are sequentially coated on the outer side of the optical fiber core from inside to outside. The whole waterproof performance is good, can be applied to outdoor operating mode.

Preferably, each sheath layer coated outside the optical fiber core has uniform thickness, stable integral structure and easy laying. The rat bite preventing capsaicin can be arranged between the inner sheath and the outer sheath, and the rat bite preventing capsaicin and the ant bite preventing capsaicin can be arranged to a certain extent.

Preferably, the armor layer is formed by lapping stainless steel bands with the compression capacity of 5000N/100mm, the bearing capacity is high, and the rat bite prevention function is good.

In another alternative embodiment, the armor layer adopts a threaded armor pipe, so that the armor layer not only has good pressure bearing capacity and is rat-bite-proof and ant-proof, but also has good deformation resistance and bending resistance, and a certain range of deformation can be generated when the armor layer is pulled or pressed in the length direction, so that damage is avoided.

Preferably, the outer sheath is a nylon sheath. The inner sheath adopts a PE sheath. In order to further improve the tensile capacity of this optical cable, can block water the yarn outer circumference equipartition and set up several tensile piece 8 at the fibre, tensile piece can adopt hemp rope or nylon rope, owing to the equipartition sets up in the outside of the yarn sheath that blocks water by spacing, very big improvement the life of optic fibre. It should be noted that the tensile member can be embedded between the armor layer and the fiber water-blocking yarn, and the tensile member has a stable structure and cannot fall off.

In an alternative embodiment, as shown in figure 2, a tensile member is provided to separate the armour layer from the fibre water-blocking yarn into an expansion joint 7 (this gap is typically within 1 mm). That is, the tensile piece separates into the gap (because the tensile piece has certain volume space, can separate armor and fibre yarn that blocks water on the radial direction of optical cable, and the expansion joint that forms not only is favorable to the optical cable to lay tensile, shock resistance when using, simultaneously, still is favorable to the heat dissipation of inside device, has improved the stability when using to, for the addition of other structures and new function, established structural basis.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
