Shielding band, shielding band effectively protects cable when cable is hung on fixed point.Cable can be equipped in above-mentioned zone
In pipe.International application WO 2004/006272A1 describe a kind of cable, the shielding strip band with partially electronically conductive material, should
Shielding strip band is laid in the region between insulated electric conductor and cable sheathing along cable.Conductor wire is in band along it
Whole length and lay and formed effectively protection with when cable is penetrated by conductive body cut off cable voltage.Moreover, pipe
It can be disposed in this cable.
The cable of the above-mentioned type is highly suitable for their purpose, but if they are equipped with the pipe for optical cable, then
It is present with problem.When manufacture or processing cable, pipe may deform, and this deformation causes that optical fiber can not possibly be installed.Such as when
Cable is hung or by binding apparatus along cable when cable end is held by suspension equipment, it is possible that this
Deformation.The cable on embedment ground may be deformed due to stone, and the cable for being even placed in seabed may be subjected to becoming pipe
The power of shape.Pipe can be made very strong so that it is resistant to deformation force.This can have the disadvantages that：Pipe can become very just
Hard and all cables will be rigid and be difficult to handle.
The content of the invention
Based on solving the above problems, the present invention provides a kind of resistant to bending flexible cable, it includes electrical transmission unit, sequentially
Ground is coated on water barrier, inner sheath, armor, the oversheath of electrical transmission unit Outer cylindrical, the quantity of the electrical transmission unit
There are 3-7, independently of one another and with being placed in water barrier, each electrical transmission unit includes point being co-located in a flexible sleeve
Be not coated with 2 power transmission conductors of insulating layer, the electrical transmission unit is cylinder, and all with water barrier inscribe；Its feature exists
In：Further include along water barrier center line extension section be n-shaped flexible core, wherein N be 3-7, the electrical transmission
Unit offers the fan groove opened up along its center line to flexible core, N number of apex angle difference of the n-shaped of the flexible core respectively
In the embedded fan groove, and the central angle of the fan groove is less than the apex angle.
According to an embodiment of the invention, the elasticity modulus of the flexible sleeve is less than the elasticity modulus of the flexible core.
According to an embodiment of the invention, the electrical transmission unit is located at being provided at the position of the water barrier phase inscribe
Elastomer inside flexible sleeve.
According to an embodiment of the invention, 2 power transmission conductors are located at the angle bisection of its corresponding central angle respectively
Line both sides.
According to an embodiment of the invention, in the spatial domain between the same each electrical transmission unit being placed in water barrier
Filled with filler material.
According to an embodiment of the invention, the filler material is any one in mineral wool rope and polypropylene fibre.
According to an embodiment of the invention, filler is filled in the flexible sleeve.
According to an embodiment of the invention, the elasticity modulus of the filler is less than the elasticity modulus of the flexible core.
Advantages of the present invention is as follows：
（1）Bending force is buffered using flexible core, prevents missing one another for electrical transmission unit；
（2）The elastomer of each electrical transmission unit can be buffered to greatest extent from extraneous stress, avoid generation pair
The excessive distortion of power transmission conductor；
（3）The fan groove of casing can cause the pressure transmission suffered by casing to flexible core, and cause casing to both sides
Pressure is discharged, internal power transmission conductor is avoided to be damaged.
Description of the drawings
Fig. 1 is the cross-sectional view of the cable of the present invention；
Fig. 2 is the force analysis figure of the cross section of the cable of the present invention.
Specific embodiment
Referring to Fig. 1, the present invention provides a kind of resistant to bending flexible cables, it includes electrical transmission unit 6, is coated in order
Water barrier 4, inner sheath 3, armor 2, the oversheath 1 of 6 Outer cylindrical of electrical transmission unit, the quantity of the electrical transmission unit 6 have
3-7, independently of one another and with being placed in water barrier 4, each electrical transmission unit 6, which includes, to be co-located in a flexible sleeve 9
Be respectively coated by 2 power transmission conductors 13 of insulating layer 12, the electrical transmission unit 6 is cylinder, and all with 4 inscribe of water barrier；
Further include the center line along water barrier 4（That is the central axis of cable）The section of extension be n-shaped flexible core 7, wherein N
For 3-7, the electrical transmission unit 6 offers the fan groove 14 opened up along its center line to flexible core 7, the flexible core 7 respectively
N number of apex angle of n-shaped be respectively embedded into the fan groove 14, and the central angle of the fan groove 14 is less than the apex angle.
Wherein, filled with filler 11 in the flexible sleeve 9, and the elasticity modulus of the flexible sleeve 9 is less than institute
