The utility model discloses a kind of cable, comprise four conductors, interior insulating case is had outside every root conductor, this cable also comprises a square external insulation sleeve and an oversheath, said four conductors are positioned at said external insulation sleeve, oversheath is positioned at outside external insulation sleeve, said oversheath outer surface is rounded, inner surface is match with external insulation sleeve square, a soft obturator is provided with in the center of external insulation sleeve, this soft obturator has four inner concaves, each inner concave and conductor match between one of them drift angle of merging and conductor being limited in inner concave and external insulation sleeve, at soft obturator center, there is cavity.The advantage of this cable is as follows: four each root conductors of conductor are all limited between one of them drift angle of its inner concave and external insulation sleeve by soft obturator, position is relatively fixing, and not easily movable, conductor adjacent is like this separated all the time, greatly reduce the generation of short circuit accident, fail safe is better.
Description
Technical field
My invention's is a kind of cable.
Background technology
Cable is used a lot at electric field, and its effect transmits electric power.The structure of general cable is that the inside is conductor, outside is sheath, insulating barrier, braid, screen etc. are had in conductor and oversheath, the problem of present cable is conductor is can be movable in oversheath, once the insulation outside conductor is gone wrong in use procedure, adjacent conductor one contacts, and just forms short circuit, after short circuit, just easily accidents caused, the most fearful just such as fire is exactly that cable short circuit causes in a lot of situation; Cable short circuit is also easy to be impacted feeder ear and electricity consumption end, and damage equipment, therefore will overcome this defect.
Utility model content
Goal of the invention of the present utility model is: invent the cable being not easy short circuit between a kind of conductor.
The cable that the utility model is invented, comprise four conductors, interior insulating case is had outside every root conductor, this cable also comprises a square external insulation sleeve and an oversheath, said four conductors are positioned at said external insulation sleeve, oversheath is positioned at outside external insulation sleeve, said oversheath outer surface is rounded, inner surface is match with external insulation sleeve square, a soft obturator is provided with in the center of external insulation sleeve, this soft obturator has four inner concaves, each inner concave and conductor match between one of them drift angle of merging and conductor being limited in inner concave and external insulation sleeve, at soft obturator center, there is cavity.
Further scheme is provided with four dovetail grooves up and down at said oversheath outer surface, is filled with glimmering agent in dovetail groove.
The advantage of this cable is as follows: four each root conductors of conductor are all limited between one of them drift angle of its inner concave and external insulation sleeve by soft obturator, position is relatively fixing, and not easily movable, conductor adjacent is like this separated all the time, greatly reduce the generation of short circuit accident, fail safe is better.

Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
Cable as shown in Figure 1, comprise four conductors 1, interior insulating case 2 is had outside every root conductor 1, this cable also comprises a square external insulation sleeve 3 and an oversheath 4, said four conductors 1 are positioned at said external insulation sleeve 3, oversheath 4 is positioned at outside external insulation sleeve 3, said oversheath 4 outer surface is rounded, inner surface is match with external insulation sleeve 3 square, a soft obturator 5 is provided with in the center of external insulation sleeve 3, this soft obturator 5 has four inner concaves 6, each inner concave 6 and conductor 1 match between one of them drift angle of merging and conductor 1 being limited in inner concave 6 and external insulation sleeve 3, at soft obturator 5 center, there is cavity 7.
In cable above: conductor 1 selects aluminum steel, copper cash or steel aluminium doublet cord; Oversheath 4 adopts rubber; External insulation sleeve 3 and interior insulating case 2 adopt wear-resisting type polythene material or low halogen type polythene material, and soft obturator 5 adopts silicones.Significantly, such material is not unique, and also have other selection in prior art, such as Taobao just discloses the insulating case of unlike material.
In cable above, its benefit is: four each root conductors 1 of conductor 1 are all limited between its inner concave 6 and one of them drift angle of external insulation sleeve 3 by soft obturator 5, position is relatively fixing, not easily movable, conductor 1 adjacent is like this separated all the time, greatly reduce the generation of short circuit accident, fail safe is better; Again on the one hand, soft obturators 5 in the center of four conductor 1 layouts, soft obturator 5 has cavity 7 simultaneously, like this when Exterior cable pressurized, will there is deformation in soft obturator 5, plays cushioning effect on the one hand, make conductor 1 and insulate not easily damaged, on the other hand, because obturator 5 soft under impaction state is also between four conductors 1 all the time, thus short circuit accident can be avoided as far as possible.
Embodiment 2:
Cable as shown in Figure 2, as different from Example 1: be provided with four dovetail grooves 8 up and down at said oversheath 4 outer surface, in dovetail groove 8, be filled with glimmering agent 9.Glimmering agent 9 is cold light sources, can be luminous, but can not generate heat, and can adopt ethylene type fluorescer, can by employing other glimmering agent commercially availabie.The distinguished place of this cable is, has four luminous zones up and down, comprehensively shows exterior feature, can be luminous when night uses, and plays warning function, especially when construction, can improve construction safety and send out.The structure of dovetail groove 8 is fine, and glimmering agent 9 spirt goes to be not easy to drop out, and easily solidifies production; Teacher auditor careful in addition and broad masses can find; if the place of dovetail groove 8 is thicker especially, and be that thick middle both sides are thin, the degree of depth of dovetail groove 8 is also just in time narrowing toward each end broad in the middle; do not destroy the thickness of whole oversheath 4 like this, thus guarantee its protective value.
Embodiment 3:
I have also thought a kind of cable, but display of not drawing, and substantially say, and be also fill fire-retardant powder in external insulation sleeve 3 from two different places above, the fail safe of such cable is better.
Significantly, the protection range that teacher auditor it should be understood that patent certainly than I write larger, literally can not understand by dead reason, protection range should be determined according to the accommodation after the understanding of technical staff.
