Wealthy market prospects.However flexible mineral matter insulated cable enhances flexibility, but also the therefore property when resisting external impacts
Can be weaker, if cable conductor is easily deformed by biggish external force, cause conductive stability to be deteriorated, and have security risk, this
Outside, when traditional flexible mineral matter insulated cable uses mica as wrapped and insulating materials, mutability is de- at powder under burning
It falls and fails.
Application No. is the Chinese patents of CN201621207339.X, disclose a kind of flexible mineral matter insulated cable.It adopts
Technical solution is: a kind of flexible mineral matter insulated cable, including cable core, the mica wrapping layer being coated on outside cable core, cladding
PE waterproof layer outside mica wrapping layer, the thermal insulation layer being coated on outside PE waterproof layer, the protective metal shell being coated on outside thermal insulation layer, packet
Overlay on the external sheath layer outside protective metal shell；The cable core include elastic supporting member for supporting optical member and be looped around four of elastic supporting member for supporting optical member surrounding it is flat
Line core, the core include conductor, the composite insulation layer outside conductor, the fire-retardant shield being coated on outside composite insulation layer
Set is equipped between the cable core and wrapping layer and is filled with inorganic thermal insulation fire-proof packing.The utility model have good waterproofness,
Thermal insulation and bending property, structure is simple, not only meets the fire-proof and water-proof demand under general environment, to external force impact resistant performance
It is good, it is highly-safe.But there is also following shortcomings for above scheme:
1, external in thermal insulation layer coats protective metal shell, increases the weight of cable, and the condition for installing stringing improves, and
Reduce the flexibility of cable.
2, when cable bend in above scheme, the heat-insulating, fire-preventing filler in outside is squeezed and deforming leads to fire-retardant shield
Set is directly contacted with mica coiling covering, reduces cable volume fire line.
Utility model content
The purpose of this utility model is to provide flexible mineral matter insulated cables, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: flexible mineral matter insulated cable, including
Core, the external of the core coat wired set, and the line set is connected and fixed with supporting element, and the supporting element is located in cable
The heart, the supporting element are equipped with connector, and the connector is connect with wrapping layer, fill out between the wrapping layer and line set
Charge, the center of the supporting element are equipped with circular hole, and running through in the circular hole has strengthening core, and the outside of the wrapping layer is coated with anti-
Water layer, the outside of the waterproof layer are coated with thermal insulation layer, and the outside of the thermal insulation layer is coated with outer jointing jacket.
Preferably, the supporting element is made using elastic high-temperature resistant rubber material.
Preferably, the strengthening core is made using aramid fiber, and uses glue sticking between strengthening core and the circular hole of supporting element.
Preferably, the outer jointing jacket is the production of low-smoke halogen-free polyolefin material.
Preferably, the filler material is inorganic mineral rope.
Compared with prior art, the utility model has the beneficial effects that being connected to support on the outside of the core of the utility model
On part, when cable bend, supporting element plays good support fixed function, and non-uniform change will not occur because of bending for core
Shape reduces fireproofing of cable so that line set is directly directly contacted with wrapping layer, and the center of supporting element is equipped with strengthening core, reinforces
Core is made by aramid fiber, have it is light-weight, feature resistant to high temperature greatly improves the tensile strength of cable.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model supporting piece structure schematic diagram.
In figure: 1 core, 2 line sets, 3 supporting elements, 4 strengthening cores, 5 wrapping layers, 6 waterproof layers, 7 thermal insulation layers, 8 outer jointing jackets, 9
Connector, 10 filler materials.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution: flexible mineral matter insulated cable, including line referring to FIG. 1-2,
Core 1, the external of the core 1 coat wired set 2, and the line set 2 is connected and fixed with supporting element 3, and the supporting element 3 is located at cable
Center, the supporting element 3 is equipped with connector 9, and the connector 9 connect with wrapping layer 5, the wrapping layer 5 and line cover 2 it
Between be filled with filler material 10, the center of the supporting element 3 is equipped with circular hole, through having strengthening core 4, the wrapping layer in the circular hole
