Abstract
The utility model relates to a layered stranded type ratproof photoelectric mixed cable comprising optical fibers, a loose tube, a filler inside the tube, a central reinforced element, copper conductors, copper conductor cushion layers, a water-blocking tape, a stainless steel band, and a flame-retardant sheath. The photoelectric mixed cable is characterized in that the loose tube and copper leads formed by the copper conductors and the copper conductor cushion layers encircle the reinforced element and are twisted; the loose tube, the copper leads and the central reinforced element are arranged in the water-blocking tape; the optical fibers and the loose tube filling compound are arranged in the loose tube; and the stainless armoured layer is arranged outside the water-blocking tape; and the flame-retardant sheath is arranged outside the armoured layer. Therefore, the stainless armoured layer is used to realize a rat biting-based damage prevention effect; and the sheath material has the flame retardant effect.
Description
Technical field
The utility model relates to the optical cable technology field, and it is a kind of layer-twisted type protection against rodents photoelectric mixed cable in definite saying.
Background technology
At present, in Communication in China, computer information industry field, the optoelectronic composite cable with broadband data transmission and function of supplying power is widely used in the communication equipment remote electric power system.And recent years; Because biting of rodent such as being subject to mouse stung; Bring very burden for design and the maintenance of photoelectric mixed cable; The destruction of mouse to photoelectric mixed cable; May cause electric leakage; Short circuit; Communication disruption; Even can blast and cause fire; Bring threat for people's life and health; Traditional photoelectric mixed cable; Adopt common steel-tape armouring; Can not effectively keep out the infringement of mouse; Finally cause twisting element destroyed; Cause inevitable loss; How effectively to avoid the infringement of the rodents such as mouse; Become the problem of communications industry joint research.
Summary of the invention
The purpose of this utility model is to provide a kind of layer-twisted type protection against rodents photoelectric mixed cable with rodent-proof characteristic.
Its characteristics are to utilize the stainless steel band armouring to replace original steel-tape armouring, utilize high wear resistance, corrosion resistance and the stable purpose that reaches the rodent destructions such as protection against rodents of stainless steel band.The technical solution of the utility model is: 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 central reinforce member, it is characterized in that: loose sleeve pipe, the cover that is surrounded by optical fiber has the insulating barrier of copper conductor and central reinforce member outside to be surrounded together by waterstop, stainless steel band armour, external sheath layer successively.Also accompany water blocking yarn between pine sleeve pipe, insulating barrier and 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 central reinforce member.External sheath layer adopts flame-retardant sheath material.
The utility model has the advantages that:
1, the stainless steel band armour that adopts has very strong wear-resisting, decay resistance, can prevent effectively that the biting of rodent such as mouse sting, and prevents that photoelectric mixed cable is destroyed, can increase the useful life of photoelectric mixed cable simultaneously;
2, the protective cover material that adopts has fire resistance, can stop or delay fire spreading with the naked light combustion;
The series of problems that 3, generally could solve with many cables can replace with a photoelectric mixed cable at this;
4, can satisfy long Distance Transmission, also sectional uses;
5, the physical characteristic that still keeps optical cable is as anti-collapse, stretching etc.;
6, have superior bending property and good anti-side pressure performance, easy construction;
7, provide simultaneously multiple transmission technology, high with the adaptability of equipment, extensibility is strong, product is widely applicable;
8, provide huge bandwidth access, guarantee the remote power feeding demand.
Description of drawings
Fig. 1 is plane structure chart of the present utility model;
Fig. 2 is production technological process of the present utility model;
In Fig. 1,1 is optical fiber, and 2 is fine cream, and 3 is loose sleeve pipe, 4 be copper cash insulating barrier, 5 for copper conductor, 6 is water blocking yarn, reinforcement centered by 7,8 is presumable reinforcement bed course, 9 is presumable gasket for packing, 10 is waterstop, 11 is stainless steel band, 12 is restrictive coating.
Embodiment
The utility model embodiment: layer-twisted type protection against rodents photoelectric mixed cable is comprised of 1 optical fiber, 2 fine cream, 3 loose sleeve pipes, 4 copper cash insulating barriers, 5 copper conductors, 6 water blocking yarns, 7 central reinforce members, 8 presumable reinforcement bed courses, 9 presumable gasket for packings, 10 waterstops, 11 stainless steel bands, 12 restrictive coatings.The copper conductor that wherein contains the loose sleeve pipe 3 of optical fiber 1 and be comprised of copper conductor 5 and copper cash insulating barrier 4 is centered around around central reinforce member 7 in the stranded mode of SZ; In 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 twisting element; Reach the purpose that blocks water; The outer vertical bag one deck stainless steel band 11 of waterstop 10; Arrive vertical bag armouring effect; Last outer jacket 12; Wherein outer jacket 12 adopts flame-retardant sheath material; Flame retardant effect.
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, squeeze into the suitable polymer pine cover of one deck and the process of filled composite resilient coating outside optical fiber 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 inner member, makes inner member avoid the impact of extraneous mechanism and environmental condition, and here we select flame-retardant sheath material to complete oversheath production, arrives fire-retardant purpose.
