The technical scheme of the utility model is that: an optical fiber armored protective type photoelectric composite cable for a base station comprises: feeder line, optical cable unit, filling rope, sheath. The base station uses the compound cable of optic fibre armor protection type photoelectricity, by 2 feeder, 2 optical cable units and many packing ropes twisted together, reuse band around wrap on the twisted body to the fixed twisted body structure, add the tear rope when increasing the sheath outside the twisted body at last, thus form the mixed cable of photoelectricity.

Specifically, two feeder lines and two optical cable units are arranged at intervals to form a bundle structure, and filling ropes are additionally arranged in gaps of the bundle structure to be stranded into a bundle cable. The bunched cable is bundled and tightened through the wrapping tape and then wraps the outer sheath, and the tearing rope is pre-buried on the inner wall of the outer sheath.

The feeder comprises a conductor and an insulating layer coated outside the conductor; the feeder is a fifth multi-strand copper conductor flexible wire of the national standard.

The optical cable unit comprises a colored optical fiber, an aramid yarn layer, a threaded armor layer and a unit sheath layer; the optical cable unit comprises one or two colored optical fibers, and a first aramid yarn layer is coated outside the colored optical fibers; the thread armor layer is sleeved outside the first aramid yarn layer; a second aramid yarn layer is coated outside the threaded armor layer; the unit sheath layer is sleeved on the second aramid yarn layer.

Preferably, the two feeder lines are arranged in a circumscribed positional relationship; the optical cable units are arranged on two sides of the section, and each optical cable unit is respectively in circumscribed position relation with the two feeder lines.

Preferably, the feeder line contains a plurality of conductors; and the conductors are arranged in an array form as a conductor bundle having a regular hexagonal cross section.

Preferably, the wrapping tape is a polyester tape or a non-woven fabric.

The utility model has the advantages that: the optical fiber armored protective type photoelectric composite cable for the base station has the advantages of small wire diameter, good flexibility, convenience in construction, reduction in purchase and construction cost, good mechanical property and temperature property, and suitability for indoor laying.

wherein: 1. an optical cable unit; 2. a PP filling rope; 3. wrapping belts; 4. a conductor; 5. an insulating layer; 6. tearing the rope; 7. an outer sheath; 11. coating the optical fiber; 12. a first aramid yarn layer; 13. a threaded armor tube; 14. a second aramid yarn layer; 15. and (4) sheathing the optical cable unit.

Detailed Description

The utility model discloses a preferred embodiment:

an optical fiber armored protective photoelectric composite cable for a base station is formed by twisting 2 feeder lines, 2 optical cable units 1 and a plurality of PP filling ropes 2 together according to a structure shown in the figure, wrapping the twisted body with a wrapping tape 3 to fix the twisted body structure, and finally adding a tearing rope 6 when an outer sheath 7 is added outside the twisted body, so that a photoelectric mixed cable is formed.

Structure of the optical cable unit 1: firstly, 1-core or 2-core coated optical fiber 11 (or tightly sleeved optical fiber) and a first aramid yarn layer 12 (or aramid yarn-free) are wrapped in a threaded armor tube 13, and then a second aramid yarn layer 14 is added outside the threaded armor tube 13, and then a layer of optical cable unit sheath 15 is extruded.

In the optical cable unit 1 of flexible screw armor, the armor that has the coiling of one deck metal thread wraps up optic fibre in the centre, and this metal screw armor 13 has very strong anti side pressure ability, simultaneously, can also keep splendid gentle bending nature for the optical cable is when having outstanding anti side pressure ability, still is keeping fine gentle bending nature.
