[0029] According to the network cable of the embodiment of the first aspect of the present invention, the network cable includes a core wire 100, an inner sheath 200, a shielding structure and an outer sheath 500; the core wire 100 includes a conductor 110, a wire sheath 120 and a first anti-oxidation layer; the conductor 110 is arranged in the wire sheath 120, and the first anti-oxidation layer is coated on the circumference of the conductor 110; the inner sheath 200 is sleeved on the outside of the core wire 100; the shielding structure includes an aluminum foil protective layer 300, a copper mesh braided layer 400 and a second anti-oxidation layer; the aluminum foil protective layer 300 is sleeved on the outside of the inner sheath 200, the copper mesh braided layer 400 is sleeved on the outside of the aluminum foil protective layer 300, and the second anti-oxidation layer is coated on the outer surface of the copper mesh braided layer 400; the outer sheath 500 is sleeved on the outside of the shielding structure.

[0030] In an embodiment of the present invention, the two ends of the core wire 100 of the network cable are used to electrically connect to two electronic devices respectively; the inner sheath 200 is sleeved on the outside of the core wire 100, and the core wire 100 can be protected by setting the inner sheath 200; the outer sheath 500 is sleeved on the outside of the shielding structure, and the shielding structure can be protected by setting the outer sheath 500; the copper mesh braided layer 400 is sleeved on the outside of the aluminum foil protective layer 300, and the copper mesh braided layer 400 can protect the aluminum foil protective layer 300, and a second anti-oxidation layer is coated on the outer surface of the copper mesh braided layer 400, and the copper mesh braided layer 400 can be protected by setting the second anti-oxidation layer, so that when the outer sheath 500 of the network cable is damaged and a gap appears due to accidental factors, the degree of oxidation of the copper mesh braided layer 400 can be reduced. , ensuring that the copper mesh braided layer 400 can work normally, so as to reduce the impact on the network cable, and the aluminum foil protective layer 300 is sleeved on the outside of the inner quilt 200. By setting the aluminum foil protective layer 300, it is possible to block external signals from entering the inner quilt 200, reduce the degree of electromagnetic interference of external signals on the core wire 100, and improve the working stability of the core wire 100. The conductor 110 of the core wire 100 is coated with a first anti-oxidation layer on the surrounding side. By setting the first anti-oxidation layer, the conductor 110 can be protected, so that when the outer quilt 500, the wire sleeve 120 and the shielding structure of the network cable are damaged and gaps appear due to accidental factors, the degree of oxidation of the conductor 110 can be reduced, so as to reduce the impact on the normal operation of the core wire 100, so as to reduce the impact on the network cable.

[0031] Specifically, the aluminum foil protective layer 300 is made of aluminum foil and polyester tape to improve the cohesiveness and adhesion of the aluminum foil protective layer 300 , so that the connection between the aluminum foil protective layer 300 and the inner quilt 200 and the copper mesh braided layer 400 is more stable.

[0032] Specifically, the aluminum foil protective layer 300 is aluminum foil Mylar.

[0033] It can be understood that the first anti-oxidation layer is a first tin-plated layer.

[0034] The first tin plating layer can be plated on the outside of the conductor 110 by chemical tin plating to form a first protective layer. The first tin plating layer can prevent the conductor 110 from directly contacting oxygen, thereby reducing the degree of oxidation of the conductor 110.

[0035] Of course, the first anti-oxidation layer may also be other protective layer structures coated around the conductor 110 , which physically separates the conductor 110 from oxygen to achieve an anti-oxidation effect.

[0036] It can be understood that the second anti-oxidation layer is a second tin-plated layer.

[0037] The second tin-plated layer can be plated on the outside of the copper mesh braided layer 400 by chemical tin plating to form a second protective layer. The second tin-plated layer can prevent the copper mesh braided layer 400 from direct contact with oxygen, thereby reducing the degree of oxidation of the copper mesh braided layer 400.

[0040] Specifically, the inner quilt 200 , the aluminum foil protective layer 300 , the copper mesh braided layer 400 and the outer quilt 500 are stacked in sequence along a direction away from the central axis of the inner quilt 200 and abut against each other in sequence.

[0041] Reference Figure 1 It can be understood that, since the core wire 100 is generally cylindrical, the inner sheath 200 , the aluminum foil protective layer 300 , the copper mesh braided layer 400 and the outer sheath 500 are all cylindrical so as to be able to match the core wire 100 .

[0042] Specifically, the diameter of the inner quilt 200, the diameter of the aluminum foil protective layer 300, the diameter of the copper mesh braided layer 400 and the diameter of the outer quilt 500 increase successively; the central axis of the inner quilt 200, the central axis of the aluminum foil protective layer 300, the central axis of the copper mesh braided layer 400 and the central axis of the outer quilt 500 are collinearly arranged.

[0045] By providing the filling line 600 , the positions between the plurality of core wires 100 can be defined, and the degree to which the core wires 100 approach the central axis of the inner blanket 200 can be reduced, thereby improving the stability of the core wires 100 in the inner blanket 200 .

[0046] Reference Figure 1 It can be understood that there are four core wires 100.

[0047] The stability of the transmission signal of the network cable can be improved by providing four core wires 100 ; specifically, the wire sheaths 120 of the four core wires 100 have different colors.

[0048] It is understandable that the outer cover 500 is made of thermoplastic polyurethane rubber to improve the wear resistance of the outer cover 500 and has high softness, which can meet the use requirements in harsh environments and reduce the possibility of the outer cover 500 being damaged due to unexpected factors.

[0049] refer to Figure 1 According to the electric device of the second embodiment of the present invention, the electric device includes the network cable of the first embodiment mentioned above.

[0050] By adopting the network cable of the embodiment of the first aspect of the above-mentioned utility model, in the embodiment of the present utility model, the two ends of the core wire 100 of the network cable are used to be electrically connected to two electronic devices respectively; the inner sheath 200 is sleeved on the outside of the core wire 100, and the core wire 100 can be protected by setting the inner sheath 200, and the outer sheath 500 is sleeved on the outside of the shielding structure, and the shielding structure can be protected by setting the outer sheath 500; the copper mesh braided layer 400 is sleeved on the outside of the aluminum foil protective layer 300, and the copper mesh braided layer 400 can protect the aluminum foil protective layer 300, and the outer surface of the copper mesh braided layer 400 is coated with a second anti-oxidation layer, and the copper mesh braided layer 400 can be protected by setting the second anti-oxidation layer, so that when the outer sheath 500 of the network cable is damaged and a gap appears due to unexpected factors, the copper mesh braided layer can be reduced. The degree of oxidation of the layer 400 ensures that the copper mesh braided layer 400 can work normally, so as to reduce the impact on the network cable, and the aluminum foil protective layer 300 is sleeved on the outside of the inner sheath 200. By setting the aluminum foil protective layer 300, it is possible to block external signals from entering the inner sheath 200, reduce the degree of electromagnetic interference of external signals on the core wire 100, and improve the working stability of the core wire 100. The conductor 110 of the core wire 100 is coated with a first anti-oxidation layer. By setting the first anti-oxidation layer, the conductor 110 can be protected, so that when the outer sheath 500, the wire sleeve 120 and the shielding structure of the network cable are damaged and gaps appear due to unexpected factors, the degree of oxidation of the conductor 110 can be reduced, so as to reduce the impact on the normal operation of the core wire 100 and reduce the impact on the network cable.
