Description
Technical field
The utility model belongs to optoelectrical cable technical field, and in particular to a kind of optoelectrical cable of night-viewable identification.
Background technology
Optoelectrical cable is that one kind integrates optical fiber, transmission of electricity copper cash, can solve broadband access, equipment electricity consumption, signal
The composite cable of transmission problem, there is the characteristics of cost is low, the few and pressure-resistant performance of space-consuming is strong, be mainly used in power communications system
In system.At present, the structure generally used for：The cable core that is twisted by optical fiber and transmission of electricity copper cash, coat successively on the outside of cable core
The armor and metal level and oversheath of its guaranteed support strength, the cable of this structure is by the larger pressure in side
When, armor and metal level can be caused directly to extrude cable core because of stress deformation, so as to be had undesirable effect to cable core, particularly
Oversheath and waterproof layer rupture are likely to result in, cable inner is intake；Secondly, in mutually twisted optical fiber and transmission of electricity copper cash,
Because the heating for copper cash of transmitting electricity can directly affect the transmission performance of optical fiber；3rd, existing optoelectrical cable does not all have night mostly
Between identification function, can be to operator in the case of being particularly badly in need of repairing or safeguarding when under night or the bad environment of illumination
Bring very big operation difficulty.
In view of the foregoing, it is necessary to design one kind can effectively waterproof and light unit will not mutual shadow with electric unit
Ring, while the night-viewable optoelectrical cable set.Therefore, the applicant has made actively effectively to explore, form down finally
The technical scheme that face will be introduced.
The content of the invention
Task of the present utility model is to provide for a kind of optoelectrical cable of night-viewable identification, advantageously improves cable core structure
Use the anti-pressure ability for improving cable core and eliminate electric unit and generate heat influence to light unit, help to improve outer jacket structure by
With the function of protecting sign and ensure its night vision identification.
What task of the present utility model was performed by, a kind of optoelectrical cable of night-viewable identification, including oversheath,
Metal level, protective layer, armor, thermal insulation layer and more than one optical transmission unit and electrical transmission unit, it is characterised in that：It is described
Optical transmission unit and electrical transmission unit be respectively separated and be arranged in thermal insulation layer, be filled with optical transport in the outside of optical transmission unit
Unit water blocking layer, electrical transmission unit water blocking layer is filled with the outside of electrical transmission unit, described armor is coated on thermal insulation layer
Outside, described protective layer pad is located between armor and metal level, and oversheath, institute are extruded with the outside of described metal level
The oversheath stated on the periphery of outside and be embedded with along its length more than at least one noctilucence identification bar.
In a specific embodiment of the present utility model, described jacket material be low density polyethylene (LDPE), in it is close
The one kind spent in polyethylene, high density polyethylene (HDPE), polyvinyl chloride or fire retardant polyolefin.
In another specific embodiment of the present utility model, described metal level be composite steel band, stainless steel band or
One kind in clad aluminum band.
In another specific embodiment of the present utility model, described protective layer is waterstop, non-woven fabrics, polyester
One kind in band, glass fibre, aramid yarn or glass fiber yarn.
In another specific embodiment of the present utility model, described armor is in metal steel wire or nonmetallic bar
One kind.
In an also specific embodiment of the present utility model, the material of described thermal insulation layer is polytetrafluoroethylene (PTFE).
In an of the present utility model and then specific embodiment, the quantity of described noctilucence identification bar is one~tri-
Bar.
Of the present utility model more and in a specific embodiment, the color of described noctilucence identification bar is one kind, two
Kind or three kinds.
It is of the present utility model and and then a specific embodiment in, described noctilucence identification bar height be slightly below institute
The outer surface for the oversheath stated.
After the utility model uses said structure, have the advantage that：Firstly, since by optical transmission unit and electrical transmission
Unit is embedded in thermal insulation layer respectively, thus when cable is by external impacts, thermal insulation layer serves the effect of buffering, counteracts
Substantial portion of pressure, considerably increase the lateral pressure resistant performance of cable；Secondly, when causing thermal insulation layer to ftracture when external force is excessive,
Water blocking layer can also prevent optical transmission unit and electrical transmission unit from intaking；3rd, because optical transmission unit and electrical transmission unit exist
It is spaced among thermal insulation layer, thus heat caused by electrical transmission unit can effectively be completely cut off by thermal insulation layer, make optical transmission unit
Transmission performance be not affected；4th, setting up for noctilucence identification bar, not only make cable that there is night identification function, and keep away
Exempt from destruction of the cable caused by towing abrasion and identifying bar to noctilucence, extend service life.
