[0020] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0021] The following describes a multi-layer shielded anti-interference connection cable according to an embodiment of the present invention in detail with reference to the accompanying drawings.

[0022] Example 1

[0023] For easier understanding, please refer to Figures 1 to 3This utility model provides an embodiment of a multi-layer shielded anti-interference connecting cable, comprising a plurality of wires 1, with a shielding mechanism disposed around the outer ring of the plurality of wires 1; the shielding mechanism comprises a first shielding layer 2, a second shielding layer 4, a second filling layer 5, a plurality of reinforcing strips 6, a third shielding layer 7, and a conductive adhesive layer 8. The first shielding layer 2 is disposed on the outer wall of the wires 1, the second shielding layer 4 is disposed on the outer ring of the plurality of wires 1, the third shielding layer 7 is disposed on the outer ring of the second shielding layer 4, the second filling layer 5 is disposed between the second shielding layer 4 and the third shielding layer 7, the plurality of reinforcing strips 6 are disposed in the second filling layer 5, and the conductive adhesive layer 8 is disposed on the outer wall of the third shielding layer 7. The wires (1) comprise conductors and an insulating layer wrapped around the outer wall of the conductors, the insulating layer being a material layer commonly used in the prior art.

[0024] It should be noted that by setting the first shielding layer 2, the second shielding layer 4, and the third shielding layer 7, the anti-shielding effect of the connecting wire is enhanced. The second filling layer 5 is set between the second shielding layer 4 and the third shielding layer 7, and the reinforcing strip 6 in the second filling layer 5 can increase the torsional resistance of the second shielding layer 4 and the third shielding layer 7, thus enhancing the protection of the second shielding layer 4 and the third shielding layer 7. Furthermore, by setting the conductive adhesive layer 8 to fill the gaps or contact surfaces of the third shielding layer 7, the conductivity of the third shielding layer 7 can be increased, so that the connecting wire can have a better anti-interference effect. In addition, the conductive adhesive layer 8 has a certain moisture-proof and protective performance, further enhancing the protective effect of the third shielding layer 7.

[0025] In some embodiments, such as Figure 1 , Figure 2 As shown, a first filling layer 3 is provided between the wire 1 and the second shielding layer 4, and the first filling layer 3 is wrapped around the outer wall of the first shielding layer 2.

[0026] It should be noted that the first shielding layer 2 can be a copper braided shielding layer, and the second shielding layer 4 and the third shielding layer 7 can be iron-silicon-aluminum alloy braided shielding layers, which have high wear resistance and hardness.

[0027] In some embodiments, such as Figure 1 , Figure 2 As shown, the second shielding layer 4 is wrapped around the outer ring of the first filling layer 3, and the outer wall of the conductive adhesive layer 8 is provided with an outer sheath 9.

[0028] It should be noted that by setting the conductive adhesive layer 8, the gaps in the third shielding layer 7 are filled and the low-frequency shielding is enhanced.

[0029] In this example, the first filling layer 3 and the second filling layer 5 can be made of aramid fiber, which is lightweight and has high strength.

[0030] In this example, the reinforcing strip 6 can be made of nylon thread. When installing the reinforcing strip 6, first wrap a second filling layer 5 around the outer wall of the second shielding layer 4, then evenly distribute the reinforcing strip 6 on the outer wall of the first wrapped second filling layer 5, and then wrap another second filling layer 5 around the outer ring of the reinforcing strip 6.

[0031] Example 2

[0032] In some embodiments, such as Figure 1 , Figure 2 As shown, the third shielding layer 7 is spirally wound around the outer ring of the second filling layer 5.

[0033] It should be noted that the second shielding layer 4 and the third shielding layer 7 are installed by spiral winding to balance the flexibility and anti-interference effect of the connecting wire.

[0034] Working principle: When installing the reinforcing strip 6, firstly, a second filling layer 5 is wound around the outer wall of the second shielding layer 4. The reinforcing strip 6 is evenly distributed on the outer wall of the first wound second filling layer 5. Then, a second filling layer 5 is wound around the outer ring of the reinforcing strip 6. After that, the third shielding layer 7 is bolted around the outer ring of the second filling layer 5. The conductive adhesive layer 8 is coated on the outer ring of the third shielding layer 7 through an extrusion coating process.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
