Abstract
The utility model discloses a silicon rubber insulated and sheath flexible type flat cable, which comprises a plurality of conductors, wherein a plurality of conductors are arranged in parallel side by side on one plane and are formed by twisting a plurality of thin copper wires which are coated with tin-plating layers; insulating layers, isolating layers and fire-resistant layers are wrapped outside a plurality of conductors sequentially; the fire-resistant layers are formed by overlaying and winding fire-resistant mica tapes, and the winding overlaying rate is more than or equal to 48 percent; sheath layers are extruded to be formed outside a plurality of conductors which are wrapped with the fire-resistant layers, the cross section of each sheath layer is in a flat shape, and a plurality of thin steel wires of which the cross sections are in a fusiform shape are arranged in the sheath layers; the diameters of the thin steel wires range from 0.85 to 2.5 millimeters; and protective layers are wrapped outside a plurality of thin steel wires sequentially. According to the silicon rubber insulated and sheath flexible type flat cable, the thin steel wires which are wrapped with the protective layers are arranged additionally in the sheath layers of the cable, so that the tensile strength of the cable in special occasions of corrosion prevention, fire prevention and the like is enhanced; and the fire-resistant layers are arranged outside a plurality of conductors of the cable, so that the fire-resistant performance of the cable is improved, and the service life of the cable is prolonged.
Description
Technical field:
The utility model relates to control cable, relates in particular to a kind of silicon rubber insulation and sheath soft type flat cable.
Background technology:
Cable is in order to transmit electricity (magnetic) ability, information and the wire product of realizing the electromagnetic energy conversion.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.Electric wire comprises that mainly bare wire, electromagnetic wire and electrical equipment and electrical are with insulated electric conductor, power cable, telecommunication cable and optical cable.
Round relatively cable; Flat cable more has advantages such as the installing space of saving and cost; And under the identical situation of heart yearn radical, its bending radius is littler than round cable, but in the operational environment of reality; Have such as industries such as metallurgy, electric power, petrochemical industry and to move in the specific (special) requirements occasion such as anticorrosion, tensile strength, the fire resistance of cable do not reach requirement.
The utility model content:
The utility model purpose provides a kind of silicon rubber insulation and sheath soft type flat cable; Be applicable to 450/750V and followingly move or fixedly lay that the electrical appliance instrument connects or signal transmits, solved cable and had special occasions tensile strength and the relatively poor defectives of fire resistance such as mobile, anticorrosion.
The utility model technical scheme is following:
Silicon rubber insulation and sheath soft type flat cable comprise several conductors, and several conductors in one plane are parallel to each other and place side by side; It is characterized in that: described several conductors all adopt the stranded bunchy of many thin copper wires that scribble tin coating to constitute; The many outer diameter ranges of thin copper wire are 0.15-0.3mm, and the outer difference of several conductors is wrap insulate layer, separator, flame retardant coating successively, and flame retardant coating adopts the overlapping wrapped formation of fire-resistant isinglass belt; Wrapped Duplication is not less than 48%; The outer extrusion moulding of several conductors of parcel flame retardant coating has restrictive coating, and the restrictive coating cross section is a flat, and being provided with the cross section in the restrictive coating is several finer wires of fusiformis; Several finer wire diameter ranges are 0.85-2.5mm, and many finer wires are enclosed with protective layer outward successively respectively.
Described silicon rubber insulation and sheath soft type flat cable, it is characterized in that: described insulating barrier, restrictive coating, protective layer material adopt equal silicon rubber.
The utility model has the advantages that:
The utility model is set up the finer wire that is enclosed with protective layer in the restrictive coating of cable; Strengthened cable and had special occasions tensile strength such as anticorrosion, fire prevention, cable adopts silicon rubber insulation and sheath simultaneously, makes cable have good cold-resistant, grease proofing, anti-wear performance; Several conductors of this outer cable are provided with flame retardant coating outward; Improve the fire resistance of cable, improved the overall performance of cable, prolonged useful life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
Silicon rubber insulation and sheath soft type flat cable comprise several conductors, and several conductors in one plane are parallel to each other and place side by side; Several conductors all adopt the many thin copper wires 2 stranded bunchys that scribble tin coating 1 to constitute; Many thin copper wire 2 outer diameter ranges are 0.15-0.3mm, and the outer difference of several conductors is wrap insulate layer 3, separator 4, flame retardant coating 5 successively, and flame retardant coating 5 adopts the overlapping wrapped formation of fire-resistant isinglass belts; Wrapped Duplication is not less than 48%; The outer extrusion moulding of several conductors of parcel flame retardant coating 5 has restrictive coating 6, and restrictive coating 6 cross sections are flat, and being provided with the cross section in the restrictive coating 6 is several finer wires 7 of fusiformis; Several finer wire 7 diameter ranges are 0.85-2.5mm, the many finer wire 7 outer protective layers 8 that are enclosed with respectively successively.
