Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

As shown in fig. 1, a composite cable comprises a power cable 1 and a signal cable 2, wherein the power cable 1 comprises a power line 11 and at least two first jackets 12, and the first jackets 12 are wrapped outside the power line 11; the signal cable 2 is provided with at least one, the signal cable 2 comprises a signal wire 21, a shielding net 22 and a second sheath 23, the signal wire 21 is provided with at least one, the shielding net 22 is wrapped outside the signal wire 21, and the second sheath 23 is wrapped outside the shielding net 22; the power cable 1 and the signal cable 2 are independently provided, and the first sheath 12 is detachably connected to the second sheath 23. The composite cable is connected through the power cable 1 and the signal cable 2 to form a composite cable structure, and the power cable 1 and the signal cable 2 are respectively independent but mutually and detachably connected, so that the composite cable of the utility model simplifies the wiring process while meeting the requirements of signal transmission and power supply, has neat and beautiful wiring, avoids the waste caused by different lengths of the existing cables, reduces the signal interference caused by the intersection between the cables, and is an optimal wiring scheme for an executive element leaving the main body equipment. The composite cable designed by the utility model can be widely applied to signal transmission and power supply between main equipment and a separation executing element, and has the advantages of convenient construction wiring and good safety performance.

In one embodiment, the power cord 11 is composed of a plurality of first wires 111 and a first insulating layer 112 wrapped around the plurality of first wires 111. The three power lines 11 are divided into a live wire (brown), a neutral wire (blue) and a ground wire (yellow or green) according to national standard, and the connecting lines of the centers of the three power lines 11 form an equilateral triangle, so that the three power lines 11 are uniformly distributed in the first sheath 12. The first conductive line 111 is a copper conductive line.

In one embodiment, the signal line 21 is composed of a plurality of second wires 211 and a second insulating layer 212 wrapped around the plurality of second wires 211. The two signal wires 21 are identical in diameter, and the centers of the two signal wires 21 and the center of the second sheath 23 are on the same straight line. The shielding net 22 is a metal woven net and can play a role in shielding interference.

In one embodiment, two signal cables 2 are respectively located at two sides of the power cable 1, the centers of the signal cable 2 and the power cable 1 are on the same straight line, the signal cable 2 and the power cable 1 are close to each other but are not in direct contact, as can be seen from fig. 1, the signal cable 2 and the power cable 1 are connected through a narrow connecting bridge 3, so that the signal cable 2 and the power cable 1 are close to each other, and indirect contact is realized. The connecting bridge 3 can be made of the same material as the first sheath 12 or the second sheath 23, and is conveniently connected with the first sheath and the second sheath by adopting the prior known bonding method; and in order to make the first sheath and the second sheath be peeled off and separated easily, the connecting bridge 3 is thinner to facilitate manual tearing or easy cutting and separation by a cutter.
