Layer and inner sheath combine together.
Further, the insulation braiding layer is woven and layer by aramid yarn high density gapless.
Further, the core further includes a wire core.
Further, the wire core is identical with the structure of the power core and control core.
Further, extruded insulation layer or semi-conductive layer.
Further, the multiple conducting wires are made of copper wire, and tin is coated with the copper wire.
Further, the multiple conducting wires are twisted to the right two-by-two first, and then stranded conducting wire twists again together two-by-two again
Into a cable core.

Further, the wire sheathing is woven and layer by stainless guiding principle silk, and the mesh number of the wire sheathing is 10 mesh.
Compared with prior art, the interior protective layer is directly extruded in after being wrapped in due to cable core extruding in insulation braiding layer
In, to fix insulated wire cores, so as to prevent from sliding between cable insulation core, add the resistance to torsion of cable.In addition, inside
Increase stainless steel wire braiding layer between oversheath, and interior protective layer is made with outer protective jacket of same material so that prevent outside
Outer protective jacket, stainless steel wire and interior protective layer combine together when sheath extrudes, so that it is guaranteed that cable entirety tension, the property of tear-proof
It can be improved.
Brief description of the drawings
The embodiment of the utility model is described below in conjunction with attached drawing, wherein：
Fig. 1 is a kind of structure diagram of mine cable provided by the utility model.
Embodiment
Specific embodiment of the utility model is further elaborated below based on attached drawing.It should be appreciated that herein
Described specific embodiment is only used as embodiment, is not used to limit the scope of protection of the utility model.
Referring to Fig. 1, it is a kind of structure diagram of mine cable provided by the utility model.The mine cable bag
Include a core 10, one layer is coated on the outer protective jacket 20 in the outside of core 10, and be filled in the outer protective jacket 20 with
Wire sheathing 30 between core 10.It is envisioned that according to the difference of practical use, the mine cable can also wrap
Include other functional layers, such as shielded layer, and using in some special occasions when be arranged on cable two special joint or
Plug etc., its technology known by those skilled in the art, no longer describes in detail herein.
The core 10 includes at least a power core 11 and a control core 12.In the present embodiment, the core 10
A wire core 13 is further included, the wire core 13 has identical structure with the power core 11 and control core 12.It is described dynamic
Power core, control core and wire core 11,12,13 include protective layer 14 in one layer respectively, and one layer is wrapped in the interior protective layer 14
In insulation braiding layer 15, and extruding is wrapped in cable core 16 in the insulation braiding layer 15.The cable core 16 is by multiple conducting wires
It is twisted to the right.Specifically, when making the cable core 16, conducting wire is twisted to the right two-by-two first, then again by this two-by-two
Stranded conducting wire is twisted into a cable core again together.The conducting wire can be made of copper wire, and be coated with tin on the copper wire.It is described
The twisted lay ratio of cable core 16 is 8-10, i.e. the ratio of pitch length and twisted wire outside diameter, wherein, pitch length is in twisted wire axis
The complete spiral spacing of one of a twisted wire on direction.The insulation braiding layer 15 is non-porous braiding layer, it can be by aramid fiber
The braiding of yarn high density gapless forms.The insulation braiding layer 15 is wrapped in the outside of the cable core 16 by extruding, so as to
To play the role of fixed insulated wire cores, and then prevent from sliding between cable insulation core, add the resistance to torsion of cable.Most
The cable core 16 for having wrapped up insulation braiding layer 15 is extruded into the interior protective layer 14 together afterwards.The interior protective layer 14 is by polyurethane warm
Thermoplastic elastic is made, i.e., is that the polyurethane with certain fluidity is wrapped in institute by frock extruding in the production process
State and be enclosed with the cable core 16 of insulation braiding layer 15, so as to form one in the power core 11, control core 12, wire core 13
Bar.As for the power core 11, the difference of core 12, wire core 13 is controlled, it is the specification of conducting wire each used, quantity,
And in outside protective layer 14 color it is different, so as to achieve the purpose that differentiation.
