Abstract
The utility model discloses a copper core polyvinyl chloride insulating parallel connection soft wire which includes two conductors arranged in parallel. The outside of the conductor is coated with a tinned layer, and the thickness of the tinned layer is 0.15 to 0.8 mm. The outside of the conductor is coated with a fire-proof layer, and the outside of the fire-proof layer is coated with an insulating layer. The outside of the insulating layers of the conductors which are arranged in parallel is coated with a cladding layer, and upper and lower sides of the cladding layer are provided inward with arc grooves in symmetry. The outside of the cladding layer is coated with a sheath layer, and an inner wall of the sheath layer is provided with bulges which match with the grooves. The inside of the bulge in the sheath layer is provided with two steel ropes which are twisted with each other. The copper core polyvinyl chloride insulating parallel connection soft wire is simple in structure, and because an outer wall of the cladding layer is provided with the arc grooves which match with the bulges on the inner wall of the sheath layer coating the cladding layer, and the steel ropes are arranged in the sheath layer, the mechanical performance of the wire is improved. At the same time, the wire has excellent heat resistance, high insulation resistance, excellent flame retardant property, excellent low smoke property, and excellent low toxicity property.
Description
Technical field:
The utility model relates to building field and uses electric wire, relates in particular to the parallel connection cord of a kind of copper core polyvinyl chloride insulation.
Background technology:
Along with scientific and technical innovation, the continuous lifting and the development of technological innovation, people improve constantly the understanding of environmental protection, and the product that requires to use must meet the Environmental Safety requirement, and greenization is nuisanceless.For this reason, develop the low smoke halogen-free flame-retardant polyolefin insulated electric conductor,, enterprise, society have all been gained merit now the great meaning of profit is in the future thousands of years as the regeneration product of polyvinyl chloride insulated electric conductor cable.
Therefore; Use the device wire connecting for ac rated voltage 450/750V and following household electrical appliance, small-sized electric instrument, instrument and meter and power and lighting; Not only need consider environmentally safe; Also should guarantee product adaptation simultaneously in the actual environment demand, the insufficient strength of original electric wire, structure inadequately problems affect such as compactness the useful life of actual electric wire.
The utility model content:
To the prior art problem, the purpose of the utility model provides the parallel connection cord of a kind of copper core polyvinyl chloride insulation, has solved the not enough defective of insufficient strength, mechanical strength of electric wire effectively.
The technical scheme of the utility model is following:
The parallel connection cord of copper core polyvinyl chloride insulation comprises it is characterized in that the conductor of two parallel placements: the conductor outside scribbles tin coating; Tin coating thickness is 0.15-0.8mm; Conductor is wrapped with flame retardant coating, and flame retardant coating is wrapped with insulating barrier, and the conductor of two parallel placements of wrap insulate layer is wrapped with lapping layer; The lapping layer upper and lower sides inwardly is arranged with the groove of arc; The lapping layer outside is enclosed with restrictive coating, and the restrictive coating inwall is provided with the convexity that matches with groove, is positioned at the steel wire rope that convexity is provided with two mutual stranded formations in the restrictive coating.
The parallel connection cord of described copper core polyvinyl chloride insulation is characterized in that: described insulating layer material adopts polyvinyl chloride.
The parallel connection cord of described copper core polyvinyl chloride insulation is characterized in that: described restrictive coating material adopts low smoke halogen-free flame-retardant polyolefin.
The material that the utility model adopted is following:
(1) conductor: conductor adopts copper free wire, surface of conductors cleaning, smooth.Conductor should satisfy among the GB/T3956 the 1st, the performance requirement of 2 kind of conductor.
(2) insulation: because the rated voltage of electric wire is lower, be generally 450/750V, used insulation crosslinked polyethylene (XLPE) material adopts the crosslinked with silicane type to get final product, and does not need the dry cross-linking type.Organosilane crosslinked polyethylene is higher than PVC temperature resistant grade, can reach 90 ℃, and uses common screw rod to extrude, and the warm water environment is crosslinked, processes very convenient.Also used vapour is crosslinked, to enhance productivity.
The advantage of the utility model:
The utlity model has simple in structure; The groove that is provided with arc at the lapping layer outer wall matches with the convexity of the restrictive coating inwall in its outside of parcel; In restrictive coating, set up steel wire rope; Improved the mechanical performance of electric wire, simultaneously, electric wire also has heat-resistant quality excellence, insulation resistance height, good flame retardant property, low cigarette, low toxicity performance.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The parallel connection cord of copper core polyvinyl chloride insulation comprises the conductor 1 of two parallel placements, and conductor 1 outside scribbles tin coating 2; Tin coating 2 thickness are 0.15-0.8mm, and conductor 1 is wrapped with flame retardant coating 3, and flame retardant coating 3 is wrapped with insulating barrier 4; The conductor 1 of two parallel placements of wrap insulate layer 4 is wrapped with lapping layer 5, and lapping layer 5 upper and lower sides inwardly are arranged with the groove 6 of arc, and lapping layer 5 outsides are enclosed with restrictive coating 7; Restrictive coating 7 inwalls are provided with the convexity 8 that matches with groove 6; Be positioned at the steel wire rope 9 that convexity 8 is provided with two mutual stranded formations in the restrictive coating 7, insulating barrier 4 materials adopt polyvinyl chloride, and restrictive coating 7 materials adopt low smoke halogen-free flame-retardant polyolefin.
