Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in figure 1, the novel wall corner wiring rat-proof composite cable comprises optical fibers 1, a water-blocking material 2, a loose tube 3 and a flame-retardant sheath 7. A plurality of optical fibers 1 and a plurality of water-blocking materials 2 are coated with loose tubes 3 to form a loose tube optical unit, as shown in figure 2. The loose tube optical unit is provided with two feeder lines 4, a layer of non-metal wires 5 is coated outside the loose tube optical unit, a right-angled triangular metal composite belt 6 is coated outside the non-metal wires 5, and a right-angled fan-shaped flame-retardant sheath 7 is coated outside the metal composite belt 6. The optical fiber 1 is a single-mode or multi-mode optical fiber after being colored, a bending loss insensitive optical fiber should be selected as much as possible, and the optical fiber is convenient to distinguish in the production, construction and use processes after being colored. The water-blocking material 2 is water-blocking yarn. The water blocking yarn expands in the presence of water, preventing water from penetrating and diffusing into the loose tube light unit. The loose tube 3 is made of polybutylene terephthalate or modified polypropylene. The heat resistance of the cable is improved. The feeder 4 is an insulated wire, and once a mouse bites the feeder, the mouse gets an electric shock, thereby protecting the intercom optical unit. The flame-retardant jacket 7 is low-smoke halogen-free polyolefin or flame-retardant polyvinyl chloride with the thickness of 1.0-1.5 mm. And the flame retardant effect of the cable is improved.

The non-metal wires 5 are water-blocking glass yarns and have a certain rat-proof effect, and in case that a rat bites the non-metal wires, the water-blocking glass yarns can sting the rat, so that the rat does not bite any more, and the damage probability of the sleeve loosening optical unit is reduced.

The metal composite belt 6 is a double-sided film-coated stainless steel belt with the thickness of 0.2-0.23mm, and in case that the flame-retardant sheath 7 is bitten and damaged, the inner-layer double-sided film-coated stainless steel belt protects internal optical fibers and wires from being corroded, has good toughness and improves the protection capability.

The working process is as follows: and paying off the optical fibers 1 and the water blocking materials 2, and extruding the loose tube 3 to form a loose tube optical unit. And then paying off a loose tube optical unit, two feeder lines 4 and a plurality of non-metallic wires 5, longitudinally wrapping a metal composite belt 6 outside, and pressing the metal composite belt 6 into a triangle through a die. The loose tube light unit is located at the right angle of the flame retardant jacket 7. And finally, extruding the flame-retardant sheath 7 outside, wherein the flame-retardant sheath 7 is extruded into a right-angled fan shape by a die, and the shape of the flame-retardant sheath is attached to a corner, so that the flame-retardant sheath is suitable for wiring at the corner. The non-metallic wires 5 and the metallic composite tape 6 provide good mechanical and ratproof properties. The optical fiber 1 is protected at the wall corner by the two feeder lines 4 arranged at the inner layer, so that even if a mouse can damage the outer layer protection, the mouse can gnaw the feeder lines to be electrically shocked, thereby protecting the internal communication optical unit.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
