Specific implementation mode

Below with reference to the attached drawing in this practical embodiment, the technical solution in this practical embodiment is carried out clear, complete Site preparation describes, it is clear that described embodiment is only this practicality a part of the embodiment, instead of all the embodiments.It is based on Embodiment in this practicality, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment belongs to the range of this practicality protection.

It will be recognized by those of ordinary skill in the art that the orientation term such as " upper end ", " lower end ", "outside", "inner" is needle For the description term of attached drawing, it is not offered as the limitation of the protection domain limited the claim.

Embodiment one：Referring to Fig. 1, the utility model provides technical solution：Few high performance flexible insulation fire prevention of connector The inside of cable, including connection sheath 1, connection sheath 1 is coated with magnalium titanium armouring sheath 2, magnalium titanium armouring shield Set 2 increases the integral strength of entire cable, simplifies when cable itself needs to reach some strength and needs the extra of additional Structure makes the whole path length of entire cable reduce, and easily facilitates installation, and connection sheath 1 is around in magnalium titanium armouring sheath 2 Outside, can be by that will connect when needing to be attached work between cable for coating entire molding Exterior cable The connection sheath 1 at end is connected, and to avoid cable and cable or cable and conductor contact position interference effect caused by external force, increases The stability connected between strong cable, the axial wrapped formation insulating layer 4 in the inside of magnalium titanium armouring sheath 2, insulating layer 4 It forms for assorted mica tape dichroic layer, clearly and is easily recognized, the mica tape color of each layer indicates the internal diameter depth of cable, makes electricity Cable have excellent high temperature resistance and flame resistance energy, and can be very good increase cable itself flexibility and softness prolong Stretching property, while the volatilization that harmful vapors are substantially not present when open fire burning is being met, safety and environmental protection, insulating layer 4 is interior to be filled with fire resisting The material of filled layer 3, insulating layer 4 is flexible material, and singly it is with fixed winding or distribution arrangement and form, and fire resisting is filled out It is powdered or graininess to fill layer 3, has good filling capacity, can fully squeeze into the gap of structure and fill up, and is increased More than two twisted copper in pencil that are internally provided with of the connective stability of each structure, fire resisting filled layer 3 twist conductor lines 5, respectively A copper twists that conductor lines 5 are twisted to be intertwined as conductor cores, and is filled as copper twists conductor lines 5, tape glass 7 and inorfil Material 8 is twisted to be twisted stranding core assembly 11, is filled with mineral-filled layer 6 between each cable core component 11, mineral are filled out in process of production It fills layer 6 to be irradiated by high-power electron beam, and one by manufacturing instrument is to have spinning for height after class crosslinking Treatment Performance, the periphery that each copper twists conductor lines 5 are filled with inorfil filler material 8, can not burn, nature blocking can be carried out to fire, Inorfil filler material 8 is coated in tape glass 7, and the burning point of the two is extremely low or can not burn at all, and inorfil is filled out Charge 8 is coated in tape glass 7, it is determined that entire inorfil filler material 8 is not loose.

Referring to Fig. 1, Fig. 2, as shown in embodiment in attached drawing, the periphery of connection sheath 1 is surrounded with non-magnetic core gold in the shape of a spiral The elasticity for belonging to material is twisted connector 9, non-conductive, and in elasticity 9 fixedly embedded insulation and obturation of twisted connector set 10, in cable When both ends need connection, in order to avoid connector is largely using the bad influence brought, the cable core inside sheath 1 can will be connected first Component 11 is electrically connected each other, will then connect 1 peptization of sheath, if connection sheath 1 is unable to reach expected length, at connecting portion The twisted connector 9 of elasticity is penetrated, the twisted connector 9 of elasticity is pulled, so that the elasticity at two end cables is twisted connector 9 and links phase Even, simultaneously as the twisted connector 9 of elasticity is integrally formed formula elastic construction with insulation and obturation set 10, the electricity at need to connect two Elasticity on cable is twisted connector 9 when reaching secured connection status, and insulation and obturation set 10, which synchronizes, to fit together, by cable core component It closes 11 junctions so that connection status is stablized.

Compared with prior art, the utility model has the beneficial effects that：The anti-thermoelectricity of few high performance flexible insulation of connector The peripheral sheath of cable uses magnesium titanium armouring sheath, has intensity high, from heavy and light, the advantage of high temperature resistant and the corruption of resistance to forceful electric power, with The oversheath cable of other metal series is compared, and body construction is simplified, and outer diameter is shunk, weight saving, electric property Constant or even also enhancing, the utility model inside has mineral-filled layer, and hands in process of production mineral-filled layer Connection processing, so that the mineral for being difficult into fibre is passed through cross-linking reaction can make its low molecular weight brittleness precursor formation moon dimension reticular structure height poly- Object makes it have spinnability, the cable after being made is being protected to assign cable soft, high fire-resistant, heat-resisting and corrosion-resistant etc. characteristics Fire protecting performance is substantially increased again while holding softness, can bear high temperature three hours in the case where loading 1000V operating conditions, together When have the function of anti-spray and mechanical impact, the overload protection ability of the utility model is strong, to the impact of high current with good Tolerance, inorfil filler material and fire resisting filled layer make it not will produce burning and extend disaster, therefore do not spread fire Calamity does not propagate fire behavior, fire-resistance property while characteristic with flexible cable also with rigid mineral insulated cable.
