It should be noted that the transmission distance of the optical fiber is 100Mbit/s for a speed of up to 2km, 1Gbit/s for 1000m and 10Gbit/s for 550 m; meanwhile, the optical fiber has the advantages of good bending: can be installed under the condition of radius less than 7.5mm, the bending loss of the cable is less than 0.2dB at 850nm and 1300nm, and the cable has very low macrobending sensitivity. Therefore, the composite connecting wire 10 is prepared by mixing the optical cable 122 and the electric wire mainly using copper as a conductor, namely, the optical cable 122 replaces part of copper wires, so that the signal transmission speed can be improved, and the dead weight and the outer diameter of the overall connecting wire can be reduced;
furthermore, two first ground wires 111 are used as the supporting wire group 110 and arranged in the middle of the cable assembly 100, which can play a similar role of filling, uniform supporting and protecting, and meanwhile, the optical cable 122 is arranged between the two power wires 121, and the power wires 121 also play a role of supporting the optical cable 122, so that the tensile property of the optical cable 122 in the drag chain process is improved, the probability that the fiber core 1221 in the optical cable 122 is torn off is reduced, and similarly, the second ground wire 132 is arranged in front of the two signal wires 131 to enhance the tensile property of the signal wires 131 and ensure that the signal wires 131 cannot break; meanwhile, the positions of the first ground wire 111/second ground wire 132 and the power line 121/signal line 131 cannot be replaced with each other, in the structural design of the present invention, the exchange of the positions of the first ground wire 111/second ground wire 132 and the power line 121/signal line 131 can lead to the increase of the outer diameter of the cable assembly 100, and the inventor of the present application finds through tests that the broken core of the power line 121/signal line 131 can occur after the exchange of the positions after 2-3 thousands of bending, and mainly because the wire rod stress and the bending degree of the composite connecting wire 10 in the middle position during bending are the largest, the ground wire with the large wire diameter and the large number of strands is selected to be placed in the middle position, so as to ensure the stability and the bending performance of the integral composite connecting wire 10, so that the mechanical performance of the integral composite connecting wire 10 is improved by the special position design, and the composite connecting wire 10 finally prepared can be tested through 500 ten thousand drag chains.

It should be noted that, because the wire diameters of the various wires are different, the positional relationships of the various wires need to be arranged, so that the outer diameter of the entire connection wire can be reduced, and the structure of the cable assembly 100 is more stable and the outer diameter can be reduced as much as possible under the adjustment of the positional relationships of the present application.
