In view of this, inventor's mat is engaged in relevant industries experience for many years, constantly concentrates on studies, and generation of the present utility model is arranged finally.That is, main purpose of the present utility model provides a kind of structure improved electric wire, it can cooperate the kelvin effect of electric current fully, and can bring into play the safe current of maximum electric wire unit cross-sectional area, and save the electric wire materials and reach, reduce the cost that electric wire is made significantly.

The purpose of this utility model is achieved in that according to a kind of structure improved electric wire of the utility model, mainly comprise an insulated hull and coat the electric wire main body that complex root conduction twisted wire constitutes, it is characterized in that: the twisted wire branch of this electric wire main body inner face is laid in the interior skin face of this insulated hull more nearby, and formation electric wire centre is hollow form, in view of the above, make its law of nature of complying with the electric current kelvin effect, make the safe traffic of the maximum unit cross-sectional area of this electric wire performance and the multinomial benifit of saving the electric wire materials significantly.

Establish with hollow or solid non-electric wire and flexual object in this electric wire body interior centre that is further characterized in that of the present utility model, makes the pliability of electric wire bending rather good.Can also the insulate plain conductor setting of appearance of electric wire main body of the present utility model.

For to the purpose of this utility model, effect and feature have further to be understood and approval, after concrete structure of the present utility model is closed accompanying drawing and is described in more detail in by following preferred embodiment mating.

Fig. 1 is the electric wire cross-sectional view strength of the utility model one preferred embodiment.

Fig. 2 is the electric wire cross-sectional view strength of another preferred embodiment of the utility model.

Fig. 3 is the electric wire cross-sectional view strength of another preferred embodiment of the utility model.

Fig. 4 is the electric wire cross-sectional view strength of another preferred embodiment of the utility model.

At first see also shown in Figure 1, the structure improved electric wire of the utility model, mainly comprise an electric wire main body 10, wherein this electric wire main body 10 coats complex root conduction twisted wire 12 by an insulated hull 11, and this conduction twisted wire 12 is located near skin face punishment cloth in this insulated hull 11 and is arranged for closely being twisted into, and the inner layer surface of close these electric wire main body 10 centers, if a wire spring 13 can support this conduction twisted wire 12, and formation electric wire main body 10 inside center places are hollow form.

The wire structure that the mat combinations thereof forms, and the kelvin effect when flowing through electric wire according to electric current, electric current flow through only on nearer several the electric twisted wires 12 of insulated hull 11, therefore very lack current flowing in the center at all, so electric wire main body 10 is made as hollow form, make the materials of electric wire save significantly, again often must be crooked to some extent according to construction environment because of this electric wire main body 10, therefore establish a wire spring 13 in the center of these electric wire main body 10 hollows, pliability in the time of can increasing by 10 bendings of electric wire main body, and can support inner conduction twisted wire.

See also shown in Figure 2 again, the wire structure of another preferred embodiment of the utility model, its mainly also comprise on the electric wire main body 10 insulated hull 11 and in this insulated hull 11 is nearer skin face punishment cloth arrange and be provided with complex root conduction twisted wire 12, and form the centre and be hollow form with first embodiment, and wherein staple line 14 is filled in this centre, also can clog chemicals (figure does not show), constitute the structure of electric wire main body 10.And establish staple line 14 because of this electric wire main body 10 hollow centre places plug, and can make the electric wire main body 10 needn't worried pliability problem, the support of inner conductive twisted wire 12 more is provided and has had elasticity concurrently.
