[0026] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the protection scope of this utility model.

[0027] In the description of the embodiments of this utility model, the term "several" means one or more, and the term "multiple" means two or more. The terms "greater than," "less than," and "exceeding" should be understood as excluding the stated number, while the terms "above," "below," and "within" should be understood as including the stated number. The terms "first" and "second" should be understood as distinguishing technical features and not as indicating or implying relative importance, the number of indicated technical features, or the order of the indicated technical features.

[0028] Reference Figure 1This utility model provides an anti-interference cable, comprising a protective layer 100, an MXene-based sponge shielding layer 200, an insulation layer 300, a filling layer 400, and multiple core units 500. The multiple core units 500 are respectively fixed to the central region of the main body of the anti-interference cable, thus providing better protection for the core units 500 used for transmitting electrical signals. This prevents the core units from contacting external objects, directly causing wear and tear, which could lead to unstable electrical signal transmission and the risk of safety accidents. In this embodiment, the multiple core units 500 are respectively wrapped and fixed by the filling layer 400. The outer surface of the filling layer 400 is attached with the insulation layer 300 to prevent the electrical signals transmitted by the multiple core units 500 from contacting the external environment and causing safety accidents. An MXene-based sponge shielding layer 200 is attached to the outer surface of the insulation layer 300. This MXene-based sponge shielding layer 200 is used to shield against external electromagnetic interference signals, preventing interference from external electromagnetic interference signals that could interfere with the electrical signals transmitted in the multiple core units 500, causing instability in the transmitted electrical signals and thus failing to meet the power supply requirements of the signal receiving equipment. A protective layer 100 is attached to the outer surface of the MXene-based sponge shielding layer, effectively protecting the internal MXene-based sponge shielding layer 200 and preventing it from being directly scratched or damaged by external objects, thus degrading its electromagnetic shielding effect. This embodiment of the invention provides an anti-interference cable that solves the technical problems of heavy cables and difficulties in cable transportation and wiring caused by using traditional metal materials as electromagnetic shielding layers, by incorporating an MXene-based sponge shielding layer to shield against external electromagnetic interference signals.

[0029] Reference Figure 2 In some embodiments, to reduce the weight per unit length of the anti-interference cable of this utility model embodiment, thereby facilitating cable transportation and laying, and to reduce manufacturing costs, the MXene-based sponge shielding layer 200 in this embodiment has an interwoven mesh structure. By attaching the interwoven mesh structure of the MXene-based sponge shielding layer 200 to the outer surface of the insulation layer 300, the weight per unit length of the anti-interference cable proposed in this utility model embodiment can be reduced while effectively shielding external electromagnetic interference signals, which is beneficial for cable transportation and construction wiring.

[0030] In some embodiments, to enhance the applicability of the anti-interference cable proposed in this utility model embodiment to special occasions, the mechanical strength of the anti-interference cable is improved. In this embodiment, the anti-interference cable further includes an armor layer. In some specific embodiments, the armor layer is disposed between the protective layer 100 and the MXene-based sponge shielding layer 200 to enhance the mechanical strength of the anti-interference cable. In other specific embodiments, the armor layer is disposed between the MXene-based sponge shielding layer 200 and the insulation layer 300, also to enhance the mechanical strength of the anti-interference cable. By providing an armor layer in this embodiment, the mechanical strength of the cable is guaranteed when applied to underground direct burial, pipeline laying, or submarine cable laying, meeting the application requirements of various special scenarios.

[0031] In one specific embodiment, the armor layer described in the above embodiments is made of any of the following materials: steel strip, steel wire, aluminum alloy or glass fiber, all of which have good mechanical strength and corrosion resistance.

[0032] Reference Figure 3 In some embodiments, the multiple core units 500 each include a wire formed by winding multiple small-section conductors 510. The wire formed by winding multiple small-section conductors has good conductivity, flexibility, and high mechanical strength. In this embodiment, each wire is wrapped with a wire insulation layer 520, and a wire shielding layer 530 is also wrapped around the wire insulation layer. Thus, the wire insulation layer 520 further achieves insulation between the wire and the outside world; in addition, the wire shielding layer 530 is used to further shield external electromagnetic interference signals, further enhancing the electromagnetic interference resistance performance of the anti-interference cable proposed in this embodiment of the present invention.

[0033] In some specific embodiments, the conductor shielding layer 520 described in the above embodiments is made of MXene-based sponge material, and in order to reduce cost and weight, the conductor shielding layer 520 is also set as an interwoven mesh structure.
