[0026] like Figure 1 As shown, the embodiment of the utility model provides a samarium iron nitrogen flame retardant magnetic data line, including:

[0027] At least 2 thin SmFeN magnetic strips, multiple copper wires and a flame retardant outer coating; wherein,

[0033] See also Figure 1 Preferably, in the above-mentioned magnetically attracted data line, there are two thin samarium iron nitride magnetic strips, and the two thin samarium iron nitride magnetic strips are symmetrically distributed and arranged around the periphery of the plurality of copper wires.

[0039] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the solution provided by the embodiments of the present invention is described in detail with specific embodiments below.

[0040] Example 1

[0041] like Figure 1 As shown, this embodiment provides a samarium iron nitrogen flame retardant magnetic data line, including:

[0042] 2 thin samarium iron nitrogen magnetic strips 2, 5 copper wires 3 and a flame retardant outer coating 1; wherein,

[0043] Five copper wires and two thin SmFeN magnetic strips are arranged together in a flame-retardant outer coating layer, the five copper wires are located in the central part of the flame-retardant outer coating layer, and the two thin SmFeN magnetic strips are symmetrically distributed and arranged around the periphery of the plurality of copper wires.

[0044] The magnetic data cable of this embodiment is prepared in the following manner:

[0045] Step 1, extruding to prepare a thin samarium iron nitride magnetic strip of suitable size; preferably, the cross-section length of the thin samarium iron nitride magnetic strip is 2 to 5 mm, and the width is 2 to 5 mm.

[0046] Step 2, a thin samarium iron nitrogen magnetic strip and a copper wire are combined to form the inner core of the magnetic data line;

[0047] Step 3: Extruding and coating a flame-retardant outer coating layer on the outer layer of the inner core to obtain a data cable, wherein the flame-retardant outer coating layer may be any one of a TPE flame-retardant outer coating layer, a TPU flame-retardant outer coating layer, a PVC flame-retardant outer coating layer, a CPE flame-retardant outer coating layer, and a flame-retardant silicone outer coating layer;

[0048] Step 4, randomly magnetize the data line so that the spatial field 3mm of the magnetic performance is greater than 100-1000Gs, thus obtaining the SmFeN flame-retardant magnetic data line.

[0049] In the above-mentioned magnetic data cable, the thickness of the flame-retardant outer coating layer is 1 to 3 mm, which is sufficient to ensure that the magnetic field can attract each other and curl.

[0050] Example 2

[0051] like Figure 2 As shown, this embodiment provides a samarium iron nitride flame retardant magnetic data cable. The main difference from Embodiment 1 is that there are three thin samarium iron nitride magnetic strips, which are distributed in an equilateral triangle and surrounded by the periphery of the multiple copper wires. This magnetic data cable can ensure a better magnetic attraction effect without affecting the flame retardant performance.

[0052] Example 3

[0053] like Figure 3As shown, this embodiment provides a samarium iron nitride flame retardant magnetic data cable. The main difference from Embodiment 1 is that there are three thin samarium iron nitride magnetic strips, which are distributed in an equilateral triangle around the periphery of seven copper wires. This magnetic data cable can ensure a better magnetic effect without affecting the flame retardant performance.

[0054] Example 4

[0055] like Figure 4 As shown, this embodiment provides a samarium iron nitride flame retardant magnetic data cable. The main difference from Embodiment 1 is that there are four thin samarium iron nitride magnetic strips, which are distributed in a pentagon and surrounded by six copper wires. This magnetic data cable can ensure a better magnetic effect without affecting the flame retardant performance.

[0056] Example 5

[0057] like Figure 5 As shown, this embodiment provides a samarium iron nitride flame retardant magnetic data cable. The main difference from Embodiment 1 is that there are 6 thin samarium iron nitride magnetic strips, and the 6 thin samarium iron nitride magnetic strips are distributed in a pentagon and arranged around the periphery of 7 copper wires. This magnetic data cable can ensure a better magnetic attraction effect without affecting the flame retardant performance.

[0058] In summary, the present invention uses extruded thin strips of samarium iron nitrogen magnetic strips as the magnetic source of the magnetic data line, which reduces the overall proportion of magnetic materials and reduces the flame retardant risk caused by magnetic materials. At the same time, multiple thin strips of samarium iron nitrogen magnetic strips are distributed in a point-like manner, which is beneficial to the magnetic effect. The outer layer uses flame-retardant materials to achieve a combination of flame retardancy and skin-friendliness. Since the copper wire and the copper wire sheath are flame retardant, the outer layer is a flame retardant layer, and the middle magnetic material layer is small in volume, it has little effect on the overall flame retardant effect, thereby forming a new type of flame retardant data line appearance. The magnetic data line can achieve V0 level flame retardancy without affecting the magnetic effect.

Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model.
