Description
Technical field
The present invention relates to a kind of cables, more particularly to a kind of photoelectric compound cable that can transmit electricity but also transmit optical signal.
Background technique
Currently, proposing new want to traditional electrical power transmission cables in certain fields with the fast development of technology
It asks, it is desirable that integrate fiber optic communication and power transmission, and intensity is good, not pliable, advantages of good shielding performance.Existing plastic optical fiber
Composite cable is made of oversheath, the insulating power core wire for being located in oversheath and twisting together and fiber unit,
Middle electric power core wire and fiber unit are just twisted together after each self-forming respectively, in the process, optical fiber occur often
The case where relatively fractureing not only causes scrapping for composite cable, while wasting the material of fiber unit；Even if being twisted into simultaneously
Function, there is also larger problems for whole intensity, there is tensile strength insufficient caused the problems such as being broken often.Therefore it needs to design
A kind of transmission performance is stable, the excellent composite cable of physical structure.
Summary of the invention
In order to solve the problems, such as involved in background technique, the present invention provides a kind of photoelectric compound cables.
The technical solution of the present invention is as follows: a kind of photoelectric compound cable, including external protection coating, the external protection coating is interior to be equipped with 4
Equipped with filled layer in the gap of root power transmission cable and 1 optical cable, the external protection coating and power transmission cable and optical cable, described 4
The line footpath of root power transmission cable is all different, any one line footpath in less than 4 power transmission cables of line footpath of the optical cable, described
Optical cable is located at 4 power transmission cable middle positions and the optical cable axis and the external protection coating axis coincide,
The sum of line footpath maximum and the line footpath taken second place are the sum of remaining power transmission cable and optical cable line footpath in 4 power transmission cables
0.85-1.15 times.
Preferably as one kind of the invention, the filled layer include the center-filled layer for wrapping up the optical cable and
Four be arranged on the center-filled layer radially fill layer, and described four radially fill layer, center-filled layer and outer protection
Layer surrounds four installation cavitys, and 4 power transmission cables are arranged in four installation cavitys, fills out in the installation cavity equipped with edge
Fill layer.
Preferably as one kind of the invention, it is 7 core cables that line footpath is the smallest in 4 power transmission cables, remaining is 19
The line of centres of core cable, 4 power transmission cables is square.
Preferably as one kind of the invention, the external protection coating is formed by multi-layer nonwoven fabrics coiling.
Preferably as one kind of the invention, the maximum cable diameter of line footpath is minimum line footpath electricity in 4 power transmission cables
1.5-3 times of cable diameter.
Preferably as one kind of the invention, the smallest cable diameter of line footpath is the line of optical cable in 4 power transmission cables
1-1.5 times of diameter.
In conclusion the invention has the following advantages that
The configuration of the present invention is simple, transmission performance are stablized, and good physical properties, cable entirety tensile strength and bending strength are equal
More outstanding, service life is longer.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
With embodiment, the invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of photoelectric compound cable, which is cylindrical body, including external protection coating 1, the external protection coating 1
4 power transmission cable 2 and 1 piece optical cables 3 are inside equipped with, are equipped in the external protection coating 1 and the gap of power transmission cable 2 and optical cable 3
The line footpath of filled layer 4,4 power transmission cables 2 is all different, and is appointed in less than 4 power transmission cables 2 of line footpath of the optical cable 3
The line footpath of root one by one, the optical cable 3 are located at 42 middle positions of power transmission cable and 3 axis of the optical cable and described
1 axis of external protection coating coincides, with the optical cable 3 be 4, center power transmission cable 2 be distributed in the counterclockwise direction and line footpath successively
Increase, in 4 power transmission cables 2 the sum of line footpath maximum and the line footpath taken second place for remaining power transmission cable 2 and 3 line footpath of optical cable it
0.85 or 0.9 or 0.95 or 1 or 1.05 or 1.1 or 1.15 times of sum.It is 7 cores electricity that line footpath is the smallest in 4 power transmission cables 2
Cable, remaining is 19 core cables.The external protection coating 1 is formed by 8 or 9 or 10 layers of non-woven fabrics coiling.4 power transmission cables 2
The middle maximum cable diameter of line footpath is 1.5 or 2 or 2.5 or 3 times of minimum line footpath cable diameter.4 power transmission cables, 2 middle line
The smallest cable diameter of diameter is 1 or 1.2 or 1.5 times of the line footpath of optical cable 3；The filled layer 4 includes wrapping the optical cable 3
The center-filled layer to wrap and four be arranged on the center-filled layer radially fill layer, and center-filled layer is positive six sides
Shape, described four radially fill layer, center-filled layer and external protection coating 1 and surround four installation cavitys, and 4 power transmission cables 2 are set
