The utility model is further arranged to：The synthetic mica tape is provided with close to the side of locating shaft and supported with locating shaft
The setting layer connect, the setting layer setting is fluted, and the lateral parts of four locating shafts are caught in groove and are connected to groove
Notch in.
By using above-mentioned technical proposal, the structural strength of synthetic mica tape is poor, therefore synthetic mica tape is arranged on
Between setting layer and protective layer, fixed synthetic mica belt shape can be played a part of.And the side of locating shaft is caught in groove,
Rotated so as to further limit locating shaft around the center of circle of protective layer, enable locating shaft to keep fixing with respect to setting layer.
The utility model is further arranged to：The bottom land of the groove abuts with the side of every locating shaft.
By using above-mentioned technical proposal, the side of locating shaft is connected to the bottom land of groove, so as to strengthen locating shaft
Connection between setting layer.
The utility model is further arranged to：Antibiotic layer is provided between the synthetic mica tape and protective layer.
By using above-mentioned technical proposal, the setting of antibiotic layer can strengthen the anti-microbial property of electric wire.
The utility model is further arranged to：The material of the antibiotic layer is Tea Polyphenols.
By using above-mentioned technical proposal, Tea Polyphenols has polyhydroxy, has good antioxidant effect.
The utility model is further arranged to：The material of the setting layer, the material of insulating barrier and locating shaft is HDPE,
The material of the protective layer is PVC.
By using above-mentioned technical proposal, HDPE has higher rigidity and toughness, and mechanical strength is good, electrical insulation capability
It is good, meet its insulating requirements as insulating barrier and the intensity requirement as setting layer and locating shaft.PVC is cheap and easy to get, has
Good mechanical strength and electrical insulation capability, meet the requirement as protective layer.
In summary, the utility model has the advantages that：
The flame-proof wire makes to form the gap full of air between synthetic mica tape and conductor by setting locating shaft, from
And strengthen heat-proof quality using the characteristics of air low thermal conductivity, coordinate the heat-proof quality of synthetic mica tape, realize the anti-of electric wire
The enhancing of fiery performance.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
Reference picture 1, a kind of flame-proof wire, include protective layer 1, antibiotic layer 2, synthetic mica tape 3 successively from outside to inside and determine
Type layer 4.The material of protective layer 1 is PVC, and the material of antibiotic layer 2 is Tea Polyphenols, and the material of synthetic mica tape 3 is synthetic mica, fixed
The material of type layer 4 is HDPE.Wherein, antibiotic layer 2 is adhered on protective layer 1.Setting layer 4 is set away from the side of synthetic mica tape 3
It is equipped with four grooves 5.Circumferencial direction equidistantly distributed of four grooves 5 along setting layer 4.In the region that setting layer 4 surrounds
Four locating shafts 6 are provided with, the material of locating shaft 6 is HDPE.Four locating shafts 6 and four grooves 5 correspond, and four fixed
The lateral parts of position axle 6 are caught in groove 5.The side of four locating shafts 6 abuts with the bottom land of groove 5 and the notch of groove 5 simultaneously.
Reference picture 1, four conductors 7 are provided between four locating shafts 6, insulating barrier 8 is enclosed with outside every conductor 7.Absolutely
The material of edge layer 8 is HDPE.The side of the insulating barrier 8 of four conductors 7 abuts from beginning to end successively.The circle of the insulating barrier 8 of four conductors 7
The heart is located on same circumference.Circumferentially two adjacent insulating barriers 8 are connected to same root locating shaft 6.Circumferentially side
To two adjacent positioned axles 6 between minimum range be less than insulating barrier 8 external diameter.
Circumferentially minimum range is less than the diameter of conductor 7 between adjacent two locating shafts 6, therefore, when
After the circumferential length of synthetic mica tape 3 and protective layer 1 is fixed, four conductors 7 can be fixed for four locating shafts 6, avoid
Four conductors 7 are moved, so that it is guaranteed that gap be present between four conductors 7 and synthetic mica tape 3.Gap is along conductor 7
Bearing of trend it is closed at both ends, air is full of in gap.Air has the characteristics of thermal conductivity factor is small, heat-proof quality is good, therefore energy
Enough strengthen the fire protecting performance of electric wire.And the main material synthetic mica of synthetic mica tape 3 is to replace hydroxyl with fluorine ion, in normal pressure
Under the conditions of the size that synthesizes is big, the complete synthetic mica of crystal formation.Synthetic mica tape 3 removes the coefficient of expansion with natural mica band
It is small, dielectric strength is big, resistivity is high and dielectric constant is uniformly etc. beyond characteristic, its temperature classification is high, can reach A level fire resisting water
It is flat, so as to further improve the fire protecting performance of electric wire.
And the structural strength of synthetic mica tape 3 is poor, and antibiotic layer 2 is attached on protective layer 1.If it will directly synthesize cloud
Master tape 3 and locating shaft 6 are abutted, then space can be formed between synthetic mica tape 3 and antibiotic layer 2, so that the volume of air reduces,
Reduce effect of heat insulation.And setting layer 4 is arranged between synthetic mica tape 3 and locating shaft 6, then can be that the volume of air to the greatest extent may be used
It can increase, while increase the girth of synthetic mica tape 3.
