Abstract
The utility model relates to a kind of multicore cable.The utility model comprises plural conductive core, each described conductor wire core is coated with insulating barrier, a plurality of described conductor wire core being coated with insulating barrier is sheathed in a protective layer, wherein, also comprise a plurality of inductance coil, each described inductance coil is around conductor wire core described in, and between the described insulating barrier being arranged at corresponding described conductor wire core and described protective layer, described protective layer is drawn at the two ends of described inductance coil; Between a plurality of described inductance coil, stagger in position.Its beneficial effect is: by surrounding the inductance coil of conductor wire core, responding to the state of conductor wire core thus carrying out on-line checkingi to cable easily; Structure is simply easy to implement.
Description
Technical field
The utility model relates to technical field of cable, particularly relates to a kind of multicore cable of convenient test.
Background technology
Cable (electric cable, power cable) normally forms by several or several groups of conductor wire cores are stranded around center, the similar rope of its shape, simultaneously outer cover height insulating barrier.Common cable comprises conductor wire core, the insulating barrier of protection conductor wire core, and the protective layer be coated on outside insulating barrier is formed.
Cable once mounted use, then is wanted to pull down very difficult, is therefore difficult to carry out open-loop test to its performance to the cable in use, carries out the work that closed loop test then can affect whole networking.
Summary of the invention
For the problems referred to above that existing cable exists, now provide a kind of multicore cable being intended to realize convenient test.
To achieve these goals, the utility model have employed following technical scheme:
A kind of multicore cable, comprise plural conductive core, each described conductor wire core is coated with insulating barrier, a plurality of described conductor wire core being coated with insulating barrier is sheathed in a protective layer, wherein, also comprise a plurality of inductance coil, each described inductance coil is around conductor wire core described in, and between the described insulating barrier being arranged at corresponding described conductor wire core and described protective layer, described protective layer is drawn at the two ends of described inductance coil; Between a plurality of described inductance coil, stagger in position.
Another aspect of the present utility model, is provided with filler layer between described insulating barrier and described protective layer, and described inductance coil is arranged in described filler layer.
Another aspect of the present utility model, described inductance coil is embedded in described protective layer.
Another aspect of the present utility model, described inductance coil is wrapped in outside described insulating barrier.
Another aspect of the present utility model, described inductance coil is printed on a film, outside insulating barrier described in described film coated or be covered on inside described protective layer.
Another aspect of the present utility model, described inductance coil is made up of copper or aluminium.
By the enforcement to technical solutions of the utility model, following technique effect can be obtained:
1, by surrounding the inductance coil of conductor wire core, responding to the state of conductor wire core thus easily on-line checkingi being carried out to cable;
2, structure is simply easy to implement.
Accompanying drawing explanation
Fig. 1 is the sectional structure chart of a kind of multicore cable of the utility model;
Fig. 2 is the end view of a kind of multicore cable of the utility model.
Embodiment
Be described the technical solution of the utility model below by way of specific embodiment, with under the conflict free prerequisite of utility model object of the present utility model, the technical characteristic in the embodiment hereinafter mentioned and embodiment can combine mutually.
As shown in Figure 1-2, the technical scheme that the utility model adopts is, a kind of multicore cable, comprise plural conductive core 1, each conductor wire core 1 is coated with insulating barrier 2, a plurality of conductor wire core 1 being coated with insulating barrier 2 is sheathed in a protective layer 3, wherein, also comprise a plurality of inductance coil 4, each inductance coil 4 is around a conductor wire core 1, and between the insulating barrier 2 being arranged at corresponding conductor wire core 1 and protective layer 3, the two ends 41 of inductance coil 4 are by extraction protective layer 3; Stagger along position on cable length direction between a plurality of inductance coil 4.
Technique scheme is by arranging the inductance coil 4 around conductor wire core 1; electric current in conductor wire core 1 and voltage is responded to by inductance coil 4; and the two ends 41 of inductance coil 4 are drawn outside protective layer 3, by being measured electric current and the voltage of conductive cable cores 1 by the two ends 41 of the inductance coil 4 outside extraction protective layer 3 when making cable use online.Meanwhile, between a plurality of inductance coil 4, stagger in position, thus make can not mutually disturb between inductance coil 4.
In further execution mode, simple electric current or voltage check device can be set outside protective layer 3, and by display unit, as LED shows, the operating state of conductor wire core 1 in the current cable of real-time instruction.
In a kind of embodiment of the present utility model, can arrange filler layer 5 between insulating barrier 2 and protective layer 3, inductance coil 4 is arranged in filler layer 5.
In a kind of embodiment of the present utility model, inductance coil 4 can be embedded in protective layer 3.
In a kind of embodiment of the present utility model, inductance coil 4 can be wrapped in outside insulating barrier 2.
In a kind of embodiment of the present utility model, inductance coil 4 can be printed on a film, outside film coated insulating barrier 2 or be covered on inside protective layer 3.
In a kind of embodiment of the present utility model, inductance coil 4 can be made up of copper or aluminium.
The above embodiments are only that part of the present utility model embodies; can not contain all of the present utility model; on the basis of above-described embodiment and accompanying drawing; those skilled in the art can obtain more execution mode under the prerequisite not paying creative work, and therefore these execution modes obtained under not paying the prerequisite of creative work all should be included in protection range of the present utility model.
