Further, the non-conductive wire rod includes one or more in nylon yarn, cotton thread, anti-elater, cellosilk.

Further, the quantity of the electric wire is at least two strands, and/or, the quantity of the elastic core is one Or multiply.

Compared to prior art, this utility model has the advantages that：

1st, because the conductor wire core of the electric wire is formed by the covered wire plying of many conductive filaments, tension so that lead The tensile strength of electric wire material is greatly improved, and fracture is less likely to occur conductive layer electric wire when telescoping collapse repeatedly, significantly Improve the service life of elastic conducting electric wire；It is filled by arranging non-conductive wire rod, not only contributes to reduce material cost And overall weight, make product lighter, frictional force can also be increased using non-conductive wire rod, play the work for tightening elastic core With, it is to avoid in telescopic process, there is delamination with elastic core in conductive layer.

2nd, because the conductive layer outer wall is coated with insulating protective layer, and the insulating protective layer preferably using insulation braiding Layer, can not only play protection, decoration function to conductive layer, can also according to actual needs by the braiding of the control 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 telescoping collapse repeatedly, abrasion is less likely to occur the insulating barrier conductive layer, solves the conductor of existing scalable wire On insulating barrier repeatedly stretch when easily because friction falls off, ultimately cause interiors of products short circuit problem.

4th, because electric wire includes many conductive filaments, at least one covered wire and insulating barriers so that per share electric wire Possess certain current capacity, can use separately as conductor, also, when the quantity of the electric wire is at least two strands, A conductor wire of the present utility model need to be only adopted during concrete application.

This utility model is described in further detail below in conjunction with drawings and Examples；But one kind of the present utility model has The multicore conductor wire of elasticity is not limited to embodiment.
