Abstract
The utility model discloses an anti-extrusion optical cable links to a home. The cable comprises a cable core which is formed by two fiber optics bundles in an elastic layer. A waterproof and damp-proof layer is disposed outside the cable core. A packing layer formed by waterproof paste is disposed between the waterproof and damp-proof layer and the cable core. Strengthening cores formed by stranding carbon fiber yarns are disposed in the packing layer on two sides of the cable core. The cable is reasonable in structure and design. The cable core is distributed in the elastic layer, so resistance to external extrusion is improved. The cable is suitable to be used outdoors, and meets indoor wiring requirements, and has excellent waterproof, moistureproof, and tensile property. After construction, the cable has long service life and good stability.
Description
Technical field
The utility model relates to optical cable, specifically is a kind of anti-extrusion type optical cable of registering one's residence.
Background technology
In the comprehensive optical fiber wiring of residential quarter and building, the outdoor optical cable that originally all adopts the 4-6 core is as the light signal leading in cable of getting involved section, outside the building carry out the welding of an optical fiber after, light signal is incorporated into indoor by the special optical cable of registering one's residence; Perhaps directly outdoor optical cable is introduced mode lead-in light signals such as machine room, commercial building.
Have certain defective mostly in the present optical cable of registering one's residence, only be adapted to house wiring mostly, outside run is registered one's residence impaired easily, such as it is impaired easily to be subjected to extraneous extruding cable core, causes optical signal transmission to be interrupted, and brings enormous economic loss to the user.
The utility model content
The purpose of this utility model provides a kind of anti-extrusion type optical cable of registering one's residence, and reasonable in design not only is fit to outdoor application but also meets the house wiring requirement, and anti-extrusion performance and water resistance are superior, good stability.
The technical solution of the utility model is as follows:
The anti-extrusion type optical cable of registering one's residence, comprise cable core, it is characterized in that: described cable core is made of two fibre bundles that are distributed in the elastic layer, cable core is provided with waterproof and dampproof layer outward, in the waterproof and dampproof layer and be filled with the packed layer that waterproof paste constitutes between the cable core, be provided with the strengthening core that the stranded bunchy of carbon fiber wire constitutes in the packed layer of cable core both sides, outer screen layer, armor, the crosslinked polyethylene restrictive coating of being provided with successively of waterproof and dampproof layer.
The described anti-extrusion type optical cable of registering one's residence is characterized in that: described elastic layer adopts the thermoplastic elastic material extrusion moulding to constitute, and the cross section is 8 fonts.
The described anti-extrusion type optical cable of registering one's residence is characterized in that: described armor adopts the steel wire spiral to twine to constitute, and twines spacing and is not more than 3 times of steel wire diameter.
Advantage of the present utility model:
Reasonable in design of the present utility model is distributed in cable core in the elastic layer, makes it anti-extraneous extrusion performance and gets a promotion, not only be fit to outdoor application but also meet the house wiring requirement, have superior waterproof and dampproof, tensile property, construction back long service life, good stability.
Description of drawings
Fig. 1 is structural representation of the present utility model.
