Abstract
The present invention provides a kind of triangle cable with optical fiber, which is four triangle cable cores being twisted in triangular structure, including triangle oversheath and oversheath, and the cable core includes one to three core in triangle insulating layer and insulating layer.Optical cable core is located at innermost layer, can not only play the role of similar steel wire armoured, can play a very good protection to Cable Core; effectively mitigate and damaged by external force; and shielding action is may also function as, effectively reduce the electromagnetic interference to electrical equipment around, and extraneous electromagnetic interference.
Description
Technical field
The present invention relates to electric wire field, is specifically a kind of triangle cable with optical fiber.
Background technology
Quad in the prior art, usual structure are that the circular core for being extruded with two insulation is twisted, or two
Root segment conductor-core is twisted.Quad core include the identical four grade cores of two cross-sectional area of conductor or three cross-sectional area of conductor it is big, one
The small 3+1 cores of cross-sectional area of conductor.Two circular cores are twisted particularly two unequal section circle cores and are twisted, core gap compared with
Greatly, not only so that cable roundness is poor, but also during extruding and construct etc. easily loosely, and core is easily altered
, outer layer need to be tightened with band when being usually added into packing material for this and be twisted together, and being twisted, and be squeezed again after twisted or stranding
Jacket.This structure quad, not only cable core stability is poor, but also material utilization amount is big, also add cable weight and cost.
Two twisted segment conductor-core structures are such as used, although cable core stability improves, core is processed into sector structure, processes compared with round wires
Core is complicated, need to strictly control segment angle and fan-shaped height, and phenomena such as in uneven thickness, insulating layer splits easily occur；Its
Secondary, either which kind of is twisted the quad of form, lay configuration so that actual core length increase, waste of materials, increase weight
Amount, cable cost increase；Again, this structure also make it that the outside diameter of cable is larger, and especially big specification cable, big outside diameter not only increases
Manufacture, transport difficult are added, and it is big to take laying space.Besides, the quad electromagnetic interference of usual structure is larger.
The prior art circular configuration outside diameter of cable is big, is laid in wire casing, especially needs multi-cable is overlapping at the same time to apply
If when, take laying space still very greatly, use is limited in small space；Secondly, more round cables lay peace together
During dress, easily wound between cable, and identify difficult, working service trouble；Again, the identification of round cable core is difficult, especially
It is two cross-section conductors, it is necessary to which every core is identified；When besides, using round cable, due to it structurally
Feature, the torsional moment that make whole cable are zero to be more difficult to, and many occasions are also needed to move repeatedly, bent using cable, or
Torsion vertical to use, that when torsion and manufacture of cable itself adds, and installation do not pay attention to increased torsion, especially vertical
In use, cable lower superposition bears to discharge the twisting resistance transmitted above, therefore twisting resistance is maximum, therefore after using the several months
Can be distorted deformation, bulge, broken skin, until fractureing cored wire.These not only easily trigger accident, cause cable short circuit or damage to set
It is standby；And cable service life is caused to shorten.Therefore still there is worth improved place.
The content of the invention
The present invention is in order to solve problem of the prior art, there is provided a kind of triangle cable with optical fiber, Cable Core is positioned at most
Inner layer, can not only play the role of similar steel wire armoured, can play a very good protection to Cable Core, effectively mitigate by
External force is damaged, and may also function as shielding action, effectively reduces the electromagnetic interference to electrical equipment around, and extraneous electromagnetic
Interference.
The cable includes the triangle that a triangle optical cable and three triangle cores being twisted around optical cable are composed
Structure, the triangle optical cable include Cable Core and coat the triangle protective layer of cable line；The triangle core
Insulating layer including some cores and core outer cladding into triangle.
Further improve, the core is one to three.
Beneficial effect of the present invention is：
1st, core and Cable Core directly drag, and save packing material and band, reduce the waste of material of twisted increase length, subtract
Light weight.
2nd, will not wind, it is easy to be identified between cable, and working service is convenient.
3rd, Cable Core is located at innermost layer, can not only play the role of similar steel wire armoured, and Cable Core can be played very
Good protective effect, effectively mitigates and is damaged by external force, and may also function as shielding action, effectively reduces to electrical equipment around
Electromagnetic interference, and extraneous electromagnetic interference.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Structure of the present invention is as shown in Figure 1, the cable includes a triangle optical cable and three triangles being twisted around optical cable
The triangular structure that core is composed, the triangle optical cable include Cable Core and coat the triangle protection of cable line
Layer；The triangle core includes some cores and core outer cladding into the insulating layer of triangle.
Further improve, the core is one to three.
The core and Cable Core of the present invention directly drags, and saves packing material and band, reduces twisted increase length
Waste of material, alleviates weight；And it will not be wound between core and Cable Core, it is easy to be identified between cable, working service side
Just.Cable Core is located at innermost layer, can not only play the role of similar steel wire armoured, and good protection can be played to Cable Core
Effect, effectively mitigates and is damaged by external force, and may also function as shielding action, effectively reduces and the electromagnetism of electrical equipment around is done
Disturb, and extraneous electromagnetic interference.
Concrete application approach of the present invention is very much, and the above is only the preferred embodiment of the present invention, it is noted that for
For those skilled in the art, without departing from the principle of the present invention, some improvement can also be made, this
A little improve also should be regarded as protection scope of the present invention.
