Abstract
The utility model relates to an electric wire comprising a guide core, an inner insulation layer, a conductor bar, a fiber braided layer and an outer insulation layer; the guide core is solid conductor and wrapped by the inner insulation layer; the conductor bar wind on the inner insulation layer in a spiral manner and is wrapped by the fiber braided layer; the fiber braided layer is wrapped by the outer insulation layer. The electric wire is good in anti-bending property, can be normally used after light damage, and is safe and reliable.
Description
Technical field
The utility model relates to a kind of electric wire, belongs to technical field of electric wires and cables.
Background technology
Electric wire refers to the material for electric power, communication and associated transport purposes.Electric wire and cable does not have strict boundary.Conventionally product few core number, that product diameter is little, simple in structure is called to electric wire, not insulation be called bare wire, other be called cable.Electric wire is made up of one or a few soft wire, and outer bread is with light and soft sheath.Along with the raising day by day of living standard, people have proposed higher performance requirement to the electric wire of electric equipment, require tensile strength high, and resistance to bending performance is good, durable in use.
At present, part adopts copper rod is drawn into after the copper wire of certain wire diameter as the wire of power line and electric heating wire, processes as insulating polymeric materials such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) in outer cladding.Although this wire also can meet the instructions for use in certain limit, in use procedure very easily due to mechanical damage or overheatedly cause that any place damages, and causes whole electric equipment to use.
Chinese patent 200920263845.4 discloses a kind of LED flexible neon, comprise heart yearn, be coated on heart yearn outside crust, be arranged on LED bulb in heart yearn and through the copper twisted wire in heart yearn, the lamp base of described LED bulb is electrically connected with copper twisted wire, in described copper twisted wire, be provided with a carbon fiber wire, described carbon fiber wire and described copper twisted wire are isometric.Though this stranded wire strength strengthens to some extent, reliability fail safe is still not good.
Summary of the invention
The technical problems to be solved in the utility model is, provides a kind of resistance to bending performance good, still can normally use safe and reliable electric wire after slightly losing.
The utility model is that the technical scheme that solves the problems of the technologies described above proposition is: a kind of electric wire, comprises and lead core, inner insulating layer, conductor bar, fiber braiding layer and external insulation layer; The described core of leading is solid conductor, described in described inner insulating layer is coated on, leads outside core, and described conductor bar is spirally wound on described inner insulating layer, and described fiber braiding layer is coated on outside described conductor bar, and described external insulation layer is coated on outside described fiber braiding layer.
The one of technique scheme is preferably: above-mentioned conductor bar has 2 to 5, and above-mentioned each conductor bar is spirally wound on described inner insulating layer side by side.
The one of technique scheme is preferably: above-mentioned conductor bar is that width is 1mm to 4mm, and thickness is 0.08mm to 0.15mm metal tape.
The one of technique scheme is preferably: the above-mentioned wire diameter of leading core is 0.3mm to 5mm.
The utlity model has positive effect: electric wire of the present utility model adopt metal coil tape around conductor as inner core, outer wrapping fiber braid, and inside and outside double insulating layer is set, and the resistance to bending performance of electric wire is promoted greatly, fatigue resistance improves more than 100% than the electric wire of common electric equipment.This wire structure adds up to rationally, and conductor adopts unlike material can make power line or electric heating wire.This electric wire has good electrical insulation capability, and higher serviceability temperature and good bending resistance folding endurance are safe and reliable when use.
