Abstract
The utility model relates to a termiteproof photoelectric mixing cable. Optical fibers are arranged in a loose tube; a fiber paste is arranged in the loose tube; copper conductors are arranged in copper wire insulated layers; and the optical fibers, the loose tube, the copper conductors, and the copper wire insulated layers encircle a central reinforced element. A water-blocking tape, a steel-plastic composite tape, and a nylon outer sheath layer successively wrap the outsides of the loose tube with coated optical fibers, the insulated layers with sleeved copper conductors, and the central reinforced element; and water-blocking yarns are arranged among the loose tube, the insulated layers and the central reinforced element. The outer sheath employs the nylon sheath material, thereby achieving objectives of enhancing the mechanical strength of the optical cable and preventing erosion of termites. And because the employed nylon sheath material is a non-toxic and harmless high-molecular polymer, no harm on the environment and the human body is caused.
Description
Technical field
The utility model relates to the optical cable technology field, and it is that a kind of physical method that utilizes reaches termite-proof purpose, and its characteristics are that photoelectric mixed cable adopts the nylon sheath wire material to reach termite-proof effect.
Background technology
Along with developing rapidly of power communication cause, the demand of photoelectric mixed cable increases severely day by day, and direct burial fiber cable is most economical system of laying, but investigate factually proof, termite is the formidable enemy who destroys the photoelectric mixed cable sheath, and termite is liked in the photoelectric mixed cable gateway and nests on every side, moth food photoelectric mixed cable outer layer plastic sheath, cause electric leakage, short circuit, communication disruption, even can blast and cause fire.Present anti-ant photoelectric mixed cable great majority adopt the anti-ant method of chemistry, utilize the toxic of chemical substance to kill termite, but therefore this chemical repellent agent serious environment pollution and being detrimental to health is researched and developed a kind of the utilization and nontoxicly can be prevented that again the physical method of ant is the development trend of industry.
Summary of the invention
The purpose of this utility model provides a kind of nontoxic termite-proof photoelectric mixed cable, the outer protective sleeve material that it is characterized in that optical cable adopts the nylon sheath wire material to replace original PE sheath, utilizes hardness and the smoothness on the surface purpose that reaches termite-proof infringement of himself.
The technical solution of the utility model: optical fiber is in loose sleeve pipe, in the pine sleeve pipe fine cream is arranged, copper conductor is in the copper cash insulating barrier, they evenly are centered around around the central reinforce member, it is characterized in that: the loose sleeve pipe, the cover that are surrounded by optical fiber have the insulating barrier of copper conductor and central reinforce member outside to be surrounded together by waterstop, composite steel-plastic belt, nylon outer sheath layer successively.Also accompany water blocking yarn between pine sleeve pipe, insulating barrier and the central reinforce member.The outer surface cover of central reinforce member has the reinforcement bed course.Be centered around the gasket for packing that has around the central reinforce member.
The beneficial effects of the utility model:
1. adopt the nylon sheath wire material to have performance wear-resisting, cold-resistant, heat-resisting, drug-resistant, increase optical cable useful life
2. its hardness of nylon sheath wire material that adopts is higher than Shao Shi D70, and has good processing characteristics.
3. fill extraordinary fine cream in the loose sleeve pipe, 100% cable core is filled total cross-section and is blocked water, and humidity resistance is good.
4. the utility model photoelectric mixed cable adopts directly buried installation, and construction operation is simple, convenient.
5. optical cable, cable composite construction can spread out of powerful electric energy and communicate optical signal simultaneously.
6. the nylon sheath wire material that adopts is a kind of nontoxic high molecular polymer, plays environmental-protection function.

Embodiment
Termite-proof photoelectric mixed cable by 1 loose sleeve pipe, 2 optical fiber, 3 fine cream, 4 copper cash insulating barriers, 5 copper conductors, 6 water blocking yarns, 7 central reinforce members, 8 reinforcement bed courses, 9 gasket for packings, 10 waterstops, 11 steel mould composite rope, 12 restrictive coatings form.The copper conductor that wherein contains the loose sleeve pipe 1 of optical fiber 2 and be comprised of copper conductor 5 and copper cash insulating barrier 4 is centered around around the central reinforce member 7 in the stranded mode of SZ, in the pine sleeve pipe 3 fine cream 2 is arranged, pine sleeve pipe 3 and copper conductor are pricked the yarn wrapping, the fixed bed structure that tangles, between the twisting element that central reinforce member and sleeve pipe and copper conductor form a water blocking yarn 6 is arranged, has good waterproof action, waterstop 10 closed pouch are rolled in around the twisting element, reach the purpose that blocks water, waterstop 10 outer vertical bag one deck composite steel-plastic belts 11, arrive the armouring effect, last outer jacket 12, wherein nylon outer sheath layer 12 adopts the nylon sheath wire material, and twisting element may have gasket for packing 9, plays the effect of interstitital texture.
This product selects the layer-twisted type structure to produce:
1, optical fiber pine cover coating
For optical property and the mechanical property of protecting optical fiber itself is not subjected to extraneous destruction, outside optical fiber coating, squeeze into the suitable polymer pine cover of one deck and the process of filled composite resilient coating.
2, copper conductor adds the insulating barrier sheath
This process is to extrude uniformly one deck insulating sleeve around copper conductor, makes the copper conductor External Insulation.
3, stranding
Stranded around central reinforce member with loose sleeve pipe, copper conductor, presumable gasket for packing, nature, and certain twisting pitch will be arranged, guarantee that the generation secondary of optical cable is remaining long.
4, oversheath
The restrictive coating of optical cable is to protect sheath; make inner member avoid the impact of extraneous mechanism and environmental condition; here we select the nylon sheath wire material to finish oversheath production; utilize that it is wear-resisting, heat-resisting, cold-resistant, drug-resistant, tough, nontoxic, absorbability is low, the hardness high, effectively arrives termite-proof purpose.
