By the above it is seen that, due to being respectively provided with an elastic insulated core 1- in every bunch core of electric conductor 1 1-3, intensity of every bunch core 1-1 when being bent can be lifted by elastic insulated line 1-1-3, and due to the elastic insulated line 1-1-3 is located in every bunch core 1-1 centre, so that cable is when carrying out electric power output or signal transmission, bullet Property insulated wire 1-1-3 core 1-1 conductive characteristic can't be impacted so that removing insulated wire cores per bunch core 1-1 Outer current-carrying part can all using same metal material, to ensure the uniformity of every bunch core size of current after powered up, So as to ensure the stable output of signal and electric power, use feeling of the lifting user when operating elevator.
Specifically, it is carbon per the elastic insulated line 1-1-3 in bunch core 1-1 in order to meet different use demands Fibre-insulated wire or vinyl chloride PVC insulated wires.And when elastic insulated line 1-1-3 uses carbon fiber insulated wire, can further carry Per bunch core 1-1 intensity in highly conductive body 1.
Also, in the present embodiment, as shown in Fig. 2 the above-mentioned every bunch core 1-1 being previously mentioned also is wrapped in comprising several Each copper conductor 1-1-1 of corresponding elastic insulated line 1-1-3 outer surfaces, and mutual stranded structure between each copper conductor 1-1-1 Into the copper intertwist body for being coated on each corresponding elastic insulated line 1-1-3 outer surfaces.Because copper conductor 1-1-1 compares other materials The plain conductor of matter has more preferable conductive characteristic, so enabling to the transmission of electric power and signal more to stablize.
In addition, as shown in figure 1, the insulator 2 employed in present embodiment is carbon fiber insulator, while insulator 2 It is interior to form multiple accommodating cavity 2-1 for being used to accommodate each electric conductor 1.
Wherein, the quantity of the accommodating cavity 2-1 in electric conductor 1 is identical with the quantity of electric conductor 1, and corresponds.Also, it is each Be spaced from each other that not connect mutually be independent cavity between accommodating cavity 2-1, and the cross sectional shape of each accommodating cavity 2-1 cavity with it is each Cross sectional shape from corresponding electric conductor 1 is identical, after each electric conductor 1 is coated in insulated body 2, each accommodating cavity of insulator 2 The outer surface of 2-1 inner surface and respective corresponding electric conductor 1 is brought into close contact.
Thus it is seen that, the insulator 2 used by the cable of present embodiment is carbon fiber insulator, and carbon is fine Multiple accommodating cavity 2-1 for being used to accommodate electric conductor 1 that are internally formed of insulator are tieed up, and each accommodating cavity 2-1 cavity is It is separate, directly each electric conductor 1 is carried out by carbon fiber insulator itself it is mutually isolated, and due to carbon fibre material phase Than having higher intensity and more preferable pliability for traditional PVC material, it is possible to effectively prevent insulator in cable Occur the phenomenon of abrasion, cracking and aging during bending, may be used also while whole cable service life is safely and effectively improved Save the insulating barrier for being coated on each surface of electric conductor 1.Simultaneously because carbon fibre material compares traditional PVC material with lighter Weight and more preferable elastic resilience, so the steel wire rope being located in inside insulator can also be saved, are produced into saving This while, can also substantially reduce the weight of whole cable so that the power consumption of elevator operationally is greatly reduced, so that It reduce further the operation and maintenance cost of whole elevator.
In addition, it is noted that in the present embodiment, as shown in Fig. 2 each electric conductor 1 is also comprising overlaying on each bunch The insulating barrier 1-2 of core 1-1 outer surfaces is constituted, can be by single electrical body by the insulating barrier 1-2 for being coated on each core 1-1 outer surfaces Each core 1-1 in 1 is completely separated so that single electrical body 1 can the different electric signal of simultaneous transmission, to ensure elevator Normal operation.
