Background technology
A kind of self-supporting cable is described in international application WO 97/40504, it has around insulated electric conductor
Shielding band, when cable is hung on fixing point, shielding band effectively protects cable.Cable can be equipped with above-mentioned zone
Pipe.International application WO 2004/006272 describes a kind of cable, and it has the shielding strip band of partially electronically conductive material, the shielding
Band lays in the region between insulated electric conductor and cable sheathing along cable.Conductor wire is whole along its in band
Length and lay and formed effectively protection with when cable is penetrated by conductive body cut off cable voltage.And, pipe also can cloth
It is placed 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
Problem occurs.When manufacturing or processing cable, pipe may deform, and this deformation causes that optical fiber can not possibly be installed.For example when
Cable is hung or by binding apparatus along cable by suspension equipment when cable end holds, it is possible that this
Deformation.The cable for imbedding ground may deform due to stone, and be even placed in the cable in seabed and may undergo to become pipe
The power of shape.Pipe can be made very strong so that its tolerance deformation force.This can have the disadvantages that：Pipe can become very firm
Hard and all cables would is that rigid and be difficult to process.
The content of the invention
Based on solving the above problems, the invention provides a kind of resistant to bending flexible cable, it includes electrical transmission unit, sequentially
Be coated on water barrier, inner sheath, armor, the oversheath of electrical transmission unit Outer cylindrical, the quantity of the electrical transmission unit
There is 3-7, independently of one another and with being placed in water barrier, each electrical transmission unit is included and is co-located in dividing in a flexible sleeve
Be not coated with 2 power transmission conductors of insulating barrier, the electrical transmission unit is cylinder, and all with water barrier inscribe；Its feature exists
In：Also include that the section extended along the center line of water barrier is the flexible core of n-shaped, wherein N is 3-7, the electrical transmission
Unit offers the fan groove opened up to flexible core along its center line, N number of drift angle difference of the n-shaped of the flexible core respectively
In the insertion fan groove, and the central angle of the fan groove is less than the drift angle.
Embodiments in accordance with the present invention, the elastic modelling quantity of the elastic modelling quantity less than the flexible core of the flexible sleeve.
It is provided with embodiments in accordance with the present invention, the electrical transmission unit and the position of the water barrier phase inscribe and is located at
Elastomer inside flexible sleeve.
Embodiments in accordance with the present invention, 2 power transmission conductors are respectively positioned at the angle bisection of its corresponding central angle
Line both sides.
Embodiments in accordance with the present invention, in the spatial domain between described same each electrical transmission unit being placed in water barrier
Filled with inserts.
Embodiments in accordance with the present invention, described inserts is any one in mineral wool rope and polypropylene fibre.
Embodiments in accordance with the present invention, are filled with filler in described flexible sleeve.
Embodiments in accordance with the present invention, the elastic modelling quantity of the elastic modelling quantity less than the flexible core of the filler.
Advantages of the present invention is as follows：
（1）Bending force is buffered using flexible core, missing one another for electrical transmission unit is prevented；
（2）The elastomer of each electrical transmission unit can be buffered from extraneous stress to greatest extent, it is to avoid be produced to transmission of electricity
The excessive distortion of conductor；
（3）The fan groove of sleeve pipe can cause the pressure transmission suffered by sleeve pipe to flexible core, and cause that sleeve pipe discharges to both sides
Pressure, it is to avoid internal power transmission conductor is damaged.
Brief description of the drawings
Fig. 1 is the cross-sectional view of cable of the invention；
Fig. 2 is the force analysis figure of the cross section of cable of the invention.
Specific embodiment
Referring to Fig. 1, the invention provides a kind of resistant to bending flexible cable, it includes electrical transmission unit 6, is coated in order
