Abstract

The utility model discloses a kind of compound telephone wire, including line to be made up of to two and Wire sheath, the line to one, line to one two mutually twisted cables one of rotation, and the line is made up of to two two mutually twisted cables two of rotation；The cable one is combined by screen layer, the insulating barrier coated successively outside conductor one and conductor one；The cable two is combined by screen layer, the insulating barrier coated successively outside conductor two and conductor two；The Wire sheath be extruded in the line to one and line to two periphery；The conductor one（7）For single oxygen-free copper, the conductor two（5）It is to be twisted by more copper free wires.The combination that conductor of the present utility model is twisted using single oxygen-free copper and Duo Gen copper free wires, strengthens its versatility, and combines both advantages, more conforms to the demand of user.

Description

A kind of compound telephone wire

Technical field

The utility model belongs to technical field of electric wires and cables, more particularly to a kind of compound telephone wire.

Background technology

The common specification of telephone wire has two cores and four cores, based on to the long-range consideration of user, typically selects four cores.And core Line is divided into rigid line and flexible cord again, and so-called rigid line is exactly single thick conductor, and flexible cord is exactly that more soft structure conductor strands form.Firmly Line has its respective advantage with flexible cord, and the tension and resistance to corrosion of rigid line are strong compared with flexible cord, the cross-sectional area of flexible cord, antifatigue energy Power, anti-Kelvin effect are strong compared with rigid line.The selection of rigid line and flexible cord is typically determined according to application places.In current telephone wire In production, a kind of line is typically only selected as conductor, so that it cannot the defects of avoiding its each.So it is badly in need of developing one kind Telephone wire, the advantage of comprehensive rigid line and flexible cord, preferably meets the needs of people.

Utility model content

To overcome drawbacks described above, the purpose of this utility model is to provide a kind of compound telephone wire.

A kind of compound telephone wire, including line are mutually rotated to two and Wire sheath, the line to one, line to one by two Twisted cable one is formed, and the line is made up of to two two mutually twisted cables two of rotation；The cable one by Screen layer, the insulating barrier coated successively outside conductor one and conductor one combines；The cable two is by conductor two and leads Screen layer, the insulating barrier coated successively outside body two combines；The Wire sheath is extruded in the line to one and line to two Periphery.

Further, the conductor one is single oxygen-free copper, and the conductor two is twisted by more copper free wires.

A kind of compound telephone wire of the utility model, compared with prior art, its advantage is：It is of the present utility model Conductor uses rigid line and flexible cord combination, strengthens its versatility, and with the stronger tension of rigid line and resistance to corrosion, flexible cord The demand that cross-sectional area is big, anti-fatigue ability is strong, anti-Kelvin effect is good advantage, more conforms to user.

Brief description of the drawings

Fig. 1 is the structural representation of the compound telephone wire of the utility model.

Shown in figure, 1- lines to one, 2- lines to two, 3- Wire sheaths, 4- cables two, 5- conductors two, 6- cables one, 7- conductors one, 8- screen layers, 9- insulating barriers.

Embodiment

Principle of the present utility model and feature are described with reference to embodiments, illustrated embodiment is served only for explaining this Utility model, it is not intended to limit the scope of the utility model.

As shown in figure 1, a kind of compound telephone wire, including line to one 1, line to 22 and Wire sheath 3, the line is to 1 It is made up of two mutually twisted cables 1 of rotation, the line mutually rotates 24 groups twisted of cable to 22 by two Into；The cable 1 is combined by screen layer 8, the insulating barrier 9 coated successively outside conductor 1 and conductor 1；It is described Cable 24 is combined by screen layer 8, the insulating barrier 9 coated successively outside conductor 25 and conductor 25；The Wire sheath 3 be extruded in the line to 1 and line to 22 periphery.

Further, the conductor 1 is single oxygen-free copper, and the conductor 25 is twisted by more copper free wires.

The scope of protection of the utility model is not limited to the technical scheme disclosed in embodiment, every according to this practicality Any modification, equivalent substitution and improvements that new technical spirit is made to above example etc., each fall within guarantor of the present utility model Protect scope.
