The utility model discloses compact structure, through the flame retarding construction who sets up different levels, the high temperature resistant ability and the flame retardant efficiency of improvement flat cable to use flexible construction to guarantee that the flat cable has the ability of better counter -bending, distortion.
Description
Technical field
The utility model belongs to the technical field of flat cable, especially a kind of flexible flame retardant flat cable.
Background technology
Flat cable is used in below operating voltage 450/750V level, the lifting that ambient temperature is-40 ~ 70 DEG C, transport, machinery, electrically, mine, etc. the power supply of the various mobile power set of industry connect and control signal illumination etc., can cable kinking be prevented.The basic structure of flat cable is arranged in parallel by multiply core, extrudes one deck rubber-type restrictive coating outward.But rubber sheath mechanical strength is relatively poor, is subject to external force and is easily destroyed, be very likely damaged to the structures such as built-in electrical insulation, cause cable bad, power failure.And the requirement of environment for use to cable self of flat cable is higher, requires that flat cable needs good flexibility, resistance to wear, high-low temperature resistant, anticorrosive property and anti-flammability.
Utility model content
The purpose of this utility model is to provide a kind of flat cable of flexible flame retardant, compact conformation, by arranging the flame retarding construction of different levels, improve the heat-resisting ability of flat cable and flame retardant effect, and flat cable has the ability of better counter-bending, distortion to use flexible structure to ensure.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of flexible flame retardant flat cable, comprise the sheath outside multiple core of parallel arrangement and core, described core is conductor from inside to outside successively, flame retardant insulation, screen and lapping layer, conductor is formed for the center of circle is stranded with aramid fiber bundle by multiply soft copper wire, flame retardant insulation comprises and is coated on the mica belt on conductor and the silastic-layer outside mica belt, described screen is worked out by tinned copper wire or copper wire, described lapping layer carries out wrapped formation by multi-layer nonwoven fabrics.
Preferably, described sheath is made up of butyronitrile polyvinyl chloride, and in sheath, bury the reinforcement that multiply is parallel to each other underground.
Preferably, hot galvanized layer is provided with outside described soft copper wire.
Preferably, described multi-layer nonwoven fabrics comprises the nonwoven layer of upper strata bonded to each other and lower floor and the glass layer in middle level.
Preferably, between the lapping layer of per share core and sheath, be equipped with colour band, and on each core, the color of colour band is different.
Preferably, described reinforcement is aramid fiber rope.
The utility model has following beneficial effect:
1, the utility model compact conformation, ingenious, the aramid fiber bundle buried underground in the aramid fiber bundle at conductor center and sheath is ensureing the intensity and the resistance to tension that strengthen cable while cable has enough flexibilities, relative to steel wire rope, again reduce the weight of cable.
2, sheath adopts butyronitrile polyvinyl chloride, there is good high-low temperature resistant, antiwear characteristic, and adopt the mode that the composite fire retardant insulating layer of mica tape and silastic-layer composition matches with nonwoven fabrics lapping layer, can effectively play fire-retardant effect, the mode that nonwoven fabrics used adopts three laminations to connect forms laminated-type nonwoven fabrics, drastically increase resistance to tension, can be wrapped tightr in wrapped process, and there will not be fracture.
3, the soft copper wire in conductor can improve the flexibility of cable, can bear and repeatedly deflect frequently, and surface is coated with hot tinning layer, can improve resistance to corrosion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1, core, 2, sheath, 3, conductor, 4, mica belt, 5, silastic-layer, 6, screen, 7, lapping layer, 8, reinforcement, 9, soft copper wire, 10, aramid fiber bundle.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
As shown in the figure: a kind of flexible flame retardant flat cable, comprise the sheath 2 outside multiple cores 1 of parallel arrangement and core 1, core 1 is from inside to outside successively by conductor 3, flame retardant insulation, screen 6 and lapping layer 7 form, conductor 3 adopts strengthened composite conductor, specifically stranded around one aramid fiber bundle 10 by multiply soft copper wire 9, and the surface of soft copper wire 9 is provided with hot galvanized layer, described flame retardant insulation comprises and is coated on the mica belt 4 on conductor 3 and the silastic-layer 5 outside mica belt 4, described screen 6 is worked out by tinned copper wire, described lapping layer 7 is with the wrapped formation of multi-layer nonwoven fabrics, described sheath 2 is made up of butyronitrile polyvinyl chloride, and in sheath 2, bury aramid fiber rope that multiply is parallel to each other underground as reinforcement 8.
Wherein, the manufacture method of described aramid fiber yarn fibre bundle 10 is: first three aramid fiber yarns are twisted into fiber element mutually, and then again carries out stranded by multiply through the stranded fiber element obtained, and finally obtains aramid fiber bundle 10.
The manufacture method of described multi-layer nonwoven fabrics is:
Method one: get two-layer nonwoven respectively as nonwoven fabrics upper strata and nonwoven fabrics lower floor, this three-decker, as intermediate layer, is then bonded together by adhesive by latticed glass layer, forms multi-layer nonwoven fabrics;
Method two: get two-layer nonwoven respectively as nonwoven fabrics upper strata and nonwoven fabrics lower floor, latticed glass layer, as intermediate layer, is then heated, pressurizes, the multi-layer nonwoven fabrics of hot pressing integralization.
Preferably, the aramid fiber rope in described sheath 2 is trapped among the outer framework forming protective wire core 1 of every root core 1.
