In addition, "first", "second", "third", and "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0028] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, or a connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figures 1 to 3 As shown, an embodiment of the utility model provides a magnetic wire, including a control wire core unit 10, a power wire core unit 20 and a braided mesh layer 30 wrapping the control wire core unit 10 and the power wire core unit 20, and the gap between the control wire core unit 10, the power wire core unit 20 and the braided mesh layer 30 is filled with cotton thread 40, which can enhance the mechanical properties and insulation properties of the wire.

[0030] The cotton thread 40 is filled along the length direction of the control wire core unit 10 and the power wire core unit 20. The outer surface of the cotton thread 40 is coated with a magnetic powder layer 41. The magnetic material layer can be continuously distributed in the wrapping material layer, so that the upper and lower layers of wires or adjacent wires can be magnetically attracted to each other by the magnetic material layer. Under the action of the magnetic field, the wires can be conveniently stacked, sorted, and wound for storage.

[0031] In this embodiment, the control wire core unit 10 includes a twisted wire pair 11, a ground wire 12, and a shielding layer 13 that wraps the twisted wire pair 11 and the ground wire 12.

The twisted wire pair 11 is formed by twisting two wires, and both wires are composed of a signal wire twisted inner conductor 111 and a second insulating layer 112 provided on the outer surface of the signal wire twisted inner conductor 111. The ground wire 12 includes a ground wire conductor 121 and a third insulator 122 provided on the outer surface of the ground wire conductor 121.
