Compared to prior art, the invention has the advantages that：
1st, because the conductor wire core of the electric wire is formed by the insulated wire plying of more conductive filaments, tension so that lead
The tensile strength of electric wire material greatly improves, and conductive layer is less likely to occur to be broken by electric wire during telescoping collapse repeatedly, significantly
Improve the service life of elastic conducting electric wire；By setting non-conductive wire rod to be filled, not only contribute to reduce material cost
And overall weight, make product lighter, non-conductive wire rod increase frictional force can also be utilized, play the work for tightening elastic core
With avoiding in telescopic process, delamination occur in conductive layer and elastic core.
2nd, because the conductive layer outer wall is coated with insulating protective layer, and the insulating protective layer is preferably using insulation braiding
Layer, can not only play protection, decoration function to conductive layer, can also be according to the braiding being actually needed by controlling the insulation braiding layer
Density adjusts the flexible ability of conductor wire.
3rd, because the insulating barrier outside the conductor wire core is abrasion-proof insulating layer, and preferably TPEE or PTEE materials so that
When conductive layer is by telescoping collapse repeatedly, the insulating barrier is less likely to occur to wear, and solves the conductor of existing scalable wire
On insulating barrier when stretching repeatedly easily because friction is fallen off, the problem of ultimately causing interiors of products short circuit.
4th, because electric wire includes more conductive filaments, at least an insulated wire and insulating barrier so that per share electric wire
Possess certain current capacity, can be used separately as conductor, also, when the quantity of the electric wire is at least two strands,
A conductor wire invented at all need to be only used during concrete application.
The present invention is described in further detail below in conjunction with drawings and Examples；But the present invention's is a kind of flexible more
Core conductor wire and preparation method thereof is not limited to embodiment.
