Abstract

The utility model discloses a bend resistant wire. The bend resistant wire comprises a wire body which is composed of conductive core beams, reinforcement ribs and an insulation layer, wherein the conductive core beams are integrally stranded or braided with the reinforcement ribs, and the insulation layer is peripherally arranged around the conductive core beams and the reinforcement ribs. According to the utility model, the conductive core beams are made by winding copper wires on aramid fiber yarns, thereby improving the linear bend resistant capacity of the conductive core beams and prolonging the services life of the wire; the conductive core beams are integrally stranded with the reinforcement ribs, so that the flexibility and pull resistance of the wire are improved, and the wire is easy to be bended and twisted, thereby effectively preventing the wire from being broken by bending or stretching and ensuring the safety in the use of the wire; and the wire has a light weight, and is particularly suitable for frequently moving electric appliances.

Description

Bending resistant electric wire

Technical field

The utility model relates to a kind of electric wire, particularly relates to a kind of bending resistant electric wire.

Background technology

As everyone knows, the electric wire of prior art mostly is to be conductor by solid or many stranded copper cash, aluminum steels, extrudes by mould with pvc material to form, and is widely used in electric power, communication and correlated current transmission field.In recent years, along with the day by day variation of household electrical appliance, the scope that electric wire is used was also more and more extensive, and various household electrical appliance, power board all need electric wire to connect.Electric wire in use, often need to move, in mobile process, unavoidably can be subject to distortion, twine, and the hardness of copper, aluminium is larger, mechanical strength is lower, regular distortion, winding are fractureed easily, and this will cause the situations such as electric current shakiness, resistance increase, and more serious problem is the accident that meeting generation short circuit or electric wire catch fire.

The utility model content

In order to solve the above problems, the purpose of this utility model is to provide a kind of stretching resistance and flexibility is good, mechanical strength is high bending resistant electric wire.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of bending resistant electric wire, comprise the line body, described line body is comprised of conductive cores bundle, reinforcement and insulating barrier, described conductive cores bundle and reinforcement is stranded or integrated by weaving, described insulating barrier is arranged at the periphery of described conductive cores bundle and reinforcement.

As improvement of the present utility model, described conductive cores bundle is to twine 2～20 tinned copper wires, bare copper wire or nickel plating copper wires by the periphery of aramid fiber yarn to be integrally formed.

As further improvement of the utility model, described reinforcement is aramid fibre or FRP fiber.

Further improve as of the present utility model, the diameter of described conductive cores bundle is greater than the diameter of reinforcement.

The beneficial effects of the utility model are: conductive cores Shu Caiyong twines copper wire at the aramid fiber yarn, thereby has strengthened the counter-bending ability of its linearity, the useful life of having improved electric wire.And conductive cores bundle and reinforcement are twisted into one, have further improved flexibility and the pull resistance of electric wire, so that electric wire is easier to bending and distortion, effectively prevent the phenomenon of electric wire because bending or stretching and fracture, and have ensured the safety in the electric wire use procedure.And electric wire weight is little, is specially adapted to roving electrical equipment and uses.
