Description

Technical Field

[0001] This utility model relates to the field of shielding materials technology, and in particular to a shielding structure, cable and electronic product. Background Technology

[0002] The motherboard and screen of a laptop are connected by a connector. Inside the connector are high-speed transmission cables, the outer layer of which is covered with shielding material to enhance the protection of the internal conductive lines. Because laptops require frequent rotation during use, the shielding material on traditional cables cannot withstand hundreds of thousands of friction cycles with the hinge. Therefore, the thickness of the shielding material must be increased (to over 80µm) to meet this requirement. However, with the increasing demand for thinner, lighter, and more shielded EMI-efficient electronic products, a thicker electromagnetic shielding material would be unsuitable for the cable routing environment.

[0003] Therefore, there is an urgent need for a shielding structure, cable, and electronic products to solve the above-mentioned technical problems. Utility Model Content

[0004] Based on the above, the purpose of this utility model is to provide a shielding structure, cable and electronic product that can improve the shielding performance, wear resistance and bending durability of the shielding structure, reduce the thickness of the shielding structure, and enable the shielding structure to withstand 500,000 cycles of rotational friction without damage or delamination.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A shielding structure includes a polyimide film layer and a conductive cloth layer, wherein the polyimide film layer and the conductive cloth layer are bonded together by an acrylic adhesive layer, and a conductive adhesive layer is attached to the side of the conductive cloth layer opposite to the acrylic adhesive layer. The overall thickness T of the polyimide film layer, the acrylic adhesive layer, the conductive cloth layer and the conductive adhesive layer after bonding is ≤0.04mm.

[0007] In some possible implementations, the thickness t1 of the polyimide film layer is 0.01±0.003 mm; the thickness t2 of the acrylic adhesive layer is 0.005 to 0.007 mm; the thickness t3 of the conductive cloth layer is 0.02±0.003 mm; and the thickness t4 of the conductive adhesive layer is 0.005 to 0.007 mm.

[0008] In some possible implementations, the thickness t1 of the polyimide film layer is 0.01 mm, the thickness t2 of the acrylic adhesive layer is 0.005 mm, the thickness t3 of the conductive cloth layer is 0.02 mm, and the thickness t4 of the conductive adhesive layer is 0.005 mm.

[0009] In some possible implementations, the shielding structure further includes a release paper layer that is adhered to the side of the conductive adhesive layer opposite to the conductive fabric layer.

[0010] In some possible implementations, the surface resistance of the conductive fabric layer is ≤0.03 ohm / sq inch, the adhesive resistance of the conductive adhesive layer is ≤0.08 ohm / sq inch, and the vertical resistance of the conductive adhesive layer is ≤0.05 ohm / sq inch.

[0011] In some possible implementations, the back adhesion between the polyimide film layer and the conductive cloth layer is ≥600 g / inch, the adhesion between the conductive cloth layer and the 304 stainless steel is ≥1000 g / inch, and the adhesion between the polyimide film layer and the 304 stainless steel is ≥400 g / inch.

[0012] In some possible implementations, the elongation of the polyimide film layer is ≥20%, and the elongation of the conductive cloth layer is ≥25%.

[0013] In some possible implementations, the shielding structure is in the form of a strip and is die-cut into a sheet-like structure.

[0014] A cable includes a conductive wire and a shielding structure as described in any of the above embodiments, wherein the shielding structure is pasted and covered on the outside of the conductive wire.

[0015] An electronic product includes a first body and a second body that are rotatably connected, and also includes a cable as described in any of the above embodiments, wherein the first body and the second body are electrically connected via the cable.

[0016] The beneficial effects of this utility model are:

[0017] The shielding structure provided by this utility model includes a polyimide film layer and a conductive cloth layer. The polyimide film layer and the conductive cloth layer are bonded together by an acrylic adhesive layer, and the conductive cloth layer is conductively bonded to the object being adhered to via the conductive adhesive layer. The polyimide film layer provides interlayer insulation, isolating the internal conductive structure from the external environment and reducing the impact of the external environment on the internal structure. The conductive cloth layer has good conductivity and electromagnetic wave shielding effect. Moreover, the conductive cloth layer is flexible, easy to process and wrap onto wires, and also has excellent bending durability, which helps to improve the torsional life of the shielding structure. The acrylic adhesive layer effectively improves the wear resistance of the shielding structure, preventing the shielding performance from decreasing due to surface damage or scratches during installation or use.

[0018] This invention ensures good shielding performance of the shielding structure without increasing the thickness of the shielding material. The overall thickness T after the polyimide film layer, acrylic adhesive layer, conductive cloth layer, and conductive adhesive layer are bonded together is ≤0.04mm. This meets the development needs of electronic products for thinner and lighter designs with high EMI shielding and can better adapt to the cable routing environment.

[0019] Cables made using this shielding structure exhibit a torsion life of ≥500,000 cycles in a torsion test within the 0–135° range. This means the cable can withstand 500,000 cycles of rotational friction without damage or delamination, while still maintaining high shielding and conductivity. The shielding performance of this structure is: 0.2dB at 3MHz, 10dB at 1GHz, and 65dB at 10GHz. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0030] This embodiment provides a shielding structure that can be applied to cables in electronic products, such as the internal high-speed transmission cables between the motherboard and screen connector of a laptop computer. This solves the problem that laptop computers and other electronic products require high-frequency rotation due to their application environment, but traditional shielding materials cannot withstand hundreds of thousands of friction cycles with the hinge, and the only solution is to increase the thickness of the shielding material.

[0031] like Figures 1 to 3As shown, the shielding structure 1000 provided in this embodiment includes a polyimide film layer 100 and a conductive cloth layer 300. The polyimide film layer 100 and the conductive cloth layer 300 are bonded together by an acrylic adhesive layer 200. A conductive adhesive layer 400 is attached to the side of the conductive cloth layer 300 opposite to the acrylic adhesive layer 200, and the conductive cloth layer 300 conducts electricity by overlapping with the object being bonded through the conductive adhesive layer 400. Specifically, the polyimide film layer 100 is a black insulating film with a hardness of 1H to 4H. The polyimide film layer 100 can achieve interlayer insulation, isolating the internal conductive structure from the external environment, thereby reducing the influence of the external environment on the internal structure. The conductive cloth layer 300 has good conductivity and electromagnetic wave shielding effect; moreover, the conductive cloth layer 300 is flexible, making it convenient for the shielding structure 1000 to be wrapped on the wire; in addition, the conductive cloth layer 300 also has excellent bending durability, which is beneficial to improving the torsional life of the shielding structure 1000. The acrylic adhesive layer 200 is coated on the surface of the conductive cloth layer 300. After bonding and curing with the polyimide film layer 100, it can form a hardened layer, which can effectively improve the wear resistance of the shielding structure 1000 and prevent the shielding performance of the shielding structure 1000 from being reduced due to damage or scratches to the surface during installation or use.

[0032] In this embodiment, the overall thickness T of the polyimide film layer 100, acrylic adhesive layer 200, conductive cloth layer 300, and conductive adhesive layer 400 after lamination is ≤0.04mm. This configuration eliminates the need to increase the thickness of the shielding structure 1000, ensuring good shielding performance. Furthermore, the shielding structure 1000 is ultra-thin and wear-resistant, meeting the development requirements of electronic products for thinner, lighter designs and high-shield EMI shielding, and better adapting to cable routing environments. Optionally, the overall thickness T of the polyimide film layer 100, acrylic adhesive layer 200, conductive cloth layer 300, and conductive adhesive layer 400 after lamination is 0.034mm to 0.04mm.

[0033] Cables made using the aforementioned shielding structure 1000 exhibit a torsion life ≥ 500,000 cycles in a torsion test within the 0–135° range. This means the cable can withstand 500,000 cycles of rotational friction without damage or delamination of the shielding structure 1000, maintaining high shielding performance and conductivity. Specifically, the shielding performance of the shielding structure 1000 is: 0.2dB at 3MHz, 10dB at 1GHz, and 65dB at 10GHz.

[0034] Optionally, in this embodiment, the thickness t1 of the polyimide film layer 100 is 0.01±0.003mm; the thickness t2 of the acrylic adhesive layer 200 is 0.005~0.007mm; the thickness t3 of the conductive cloth layer 300 is 0.02±0.003mm; and the thickness t4 of the conductive adhesive layer 400 is 0.005~0.007mm. This embodiment, through the combination of the above layer thicknesses, effectively improves the wear resistance and flexibility of the shielding structure 1000 while ensuring good shielding performance, and also achieves a relatively thin thickness. Specifically, the thickness t1 of the polyimide film layer 100 is 0.01mm, the thickness t2 of the acrylic adhesive layer 200 is 0.005mm, the thickness t3 of the conductive cloth layer 300 is 0.02mm, and the thickness t4 of the conductive adhesive layer 400 is 0.005mm.

[0035] Furthermore, the shielding structure 1000 in this embodiment also includes a release paper layer 500, which is attached to the side of the conductive adhesive layer 400 opposite to the conductive cloth layer 300. The release paper layer 500 serves as a protective layer, primarily used to protect the shielding structure 1000 during transportation and storage; when the shielding structure 1000 needs to be used, the release paper layer 500 can simply be removed. In this embodiment, the material and thickness of the release paper layer 500 are not specifically limited; appropriate release paper can be selected according to requirements, as long as it serves to protect the conductive adhesive layer 400.

[0036] In this embodiment, the surface resistance of the conductive fabric layer 300 is ≤0.03 ohm / sq inch, the adhesive resistance of the conductive adhesive layer 400 is ≤0.08 ohm / sq inch, and the vertical resistance of the conductive adhesive layer 400 is ≤0.05 ohm / sq inch. Specifically, the above performance parameters can be achieved by selecting conductive fabric layer 300 and conductive adhesive layer 400 with corresponding material properties. In this embodiment, the low resistance of conductive fabric layer 300 and conductive adhesive layer 400 ensures that the shielding structure 1000 has good conductivity.

[0037] Furthermore, in this embodiment, taking 304 stainless steel as the substrate, the polyimide film layer 100 achieves a back adhesion of ≥600g / inch with the conductive cloth layer 300 through the acrylic adhesive layer 200; the conductive cloth layer 300 achieves an adhesion of ≥1000g / inch with the 304 stainless steel through the conductive adhesive layer 400; and the polyimide film layer 100 achieves an adhesion of ≥400g / inch with the 304 stainless steel through the acrylic adhesive layer 200, the conductive cloth layer 300, and the conductive adhesive layer 400. This configuration ensures reliable adhesion between the shielding structure 1000 and the 304 stainless steel, preventing delamination or detachment of the shielding structure 1000 during use.

[0038] Optionally, in this embodiment, the elongation of the polyimide film layer 100 is ≥20%, and the elongation of the conductive cloth layer 300 is ≥25%. This gives the shielding structure 1000 good ductility and flexibility, facilitating its fabrication and allowing it to be easily wrapped around a wire. Specifically, the above performance parameters can be achieved by selecting polyimide film layer 100 and conductive cloth layer 300 with appropriate material properties.

[0039] This embodiment also provides a cable, including a conductive wire and the aforementioned shielding structure 1000, wherein the shielding structure 1000 is adhered and wrapped around the outside of the conductive wire. The cable of this embodiment has good shielding, conductivity, abrasion resistance, and bending durability, and can withstand 500,000 cycles of rotational friction without damage or delamination. Further, as... Figure 2 and Figure 3 As shown, the shielding structure 1000 in this embodiment is strip-shaped and is die-cut into multiple individual sheet-like structures. The sheet-like shielding structure 1000 is easier to wrap around conductive wires and facilitates the positioning of the wrapping position, improving the accuracy and reliability of the bonding.

[0040] Continue to refer to Figure 3 In this embodiment, the sheet-like shielding structure 1000 is a parallelogram with an included angle α of 135 degrees between adjacent sides. One end of the sheet-like shielding structure 1000 is a positioning part 1001 for easy positioning on the cable, and the other end is provided with a clamping part 1002 for easy peeling off the release paper layer 500 and easy clamping of the shielding structure 1000. For example, the total length L1 of the sheet-like shielding structure 1000 is 53.81±0.20mm, the length L2 of the positioning part 1001 is 12.94±0.20mm, the total width W1 of the sheet-like shielding structure 1000 is 8.00±0.10mm, and the width W2 of the clamping part 1002 is 4.73±0.10mm.

[0041] This embodiment also provides an electronic product, including a first body and a second body rotatably connected, and the aforementioned cable, with the first body and the second body electrically connected via the cable. Specifically, the electronic product can be a laptop computer, wherein the first body and the second body are respectively the motherboard and screen of the laptop computer, and the motherboard and screen are connected via a connector, which contains the aforementioned cable. By employing the aforementioned cable, the electronic product of this embodiment improves the shielding performance and wear resistance of the electronic product, thereby increasing its service life.

[0042] To facilitate understanding of the advantages of this utility model, fatigue tests were conducted on cable bundles covered with the shielding structure 1000 through one embodiment and three comparative examples. Table 1 below compares the performance indicators such as resistance value, peel strength, and shielding performance of the embodiment and the three comparative examples of this utility model.

[0043] As shown in Table 1, in this fatigue test, the total thickness (excluding release paper) of the shielding structure 1000 provided in this embodiment of the present invention is 40 μm, wherein the thickness of the polyimide film layer 100 is 10 μm, the thickness of the conductive cloth layer 300 is 20 μm, the thickness of the conductive adhesive layer 400 is 5 μm, and the thickness of the acrylic adhesive layer 200 is 5 μm. In Comparative Example 1, the total thickness of the shielding structure is 10.1 μm, wherein the thickness of the polyimide film layer is 5 μm, the thickness of the conductive cloth layer is 0.1 μm, and the thickness of the conductive adhesive layer is 5 μm. No acrylic adhesive layer was provided in Comparative Example 1. In Comparative Example 2, the total thickness of the shielding structure is 38.2 μm, wherein the thickness of the polyimide film layer is 30 μm, the thickness of the conductive cloth layer is 0.2 μm, and the thickness of the conductive adhesive layer is 8 μm. No acrylic adhesive layer was provided in Comparative Example 2. In Comparative Example 3, the total thickness of the shielding structure is 60.6 μm, of which the thickness of the polyimide film layer is 50 μm, the thickness of the conductive cloth layer is 0.6 μm, and the thickness of the conductive adhesive layer is 10 μm. No acrylic adhesive layer is provided in Comparative Example 3. Before testing, the resistance of the shielding structure 1000 provided in this embodiment of the present invention is 0.1 Ω, the resistance of Comparative Example 1 is 1.3 Ω, the resistance of Comparative Example 2 is 1.4 Ω, and the resistance of Comparative Example 3 is 1 Ω. The resistance value of this embodiment of the present invention is significantly lower than that of Comparative Examples 1-3. Furthermore, the peel strength of the shielding structure 1000 relative to the conductive wire provided in this embodiment of the present invention is 2 kgf / cm, the peel strength of Comparative Example 1 relative to the conductive wire is 1.27 kgf / cm, the peel strength of Comparative Example 2 relative to the conductive wire is 1.25 kgf / cm, and the peel strength of Comparative Example 3 relative to the conductive wire is 1.2 kgf / cm. The peel strength of this embodiment of the present invention relative to the conductive wire is significantly higher than that of Comparative Examples 1-3. Meanwhile, the EMI shielding performance of this embodiment is 10dB at 1GHz, the EMI shielding performance of Comparative Example 1 is 60dB at 1GHz, the EMI shielding performance of Comparative Example 2 is 60dB at 1GHz, and the EMI shielding performance of Comparative Example 3 is 70dB at 1GHz. The EMI shielding performance of this embodiment is significantly better than that of Comparative Examples 1-3.

[0044] Table 1. Data from the 500,000 torsion tests at 135 degrees.

[0045]

[0046] Through 500,000 torsion tests at 135 degrees on multiple cable samples, the shielding structure 1000 of this embodiment maintained its normal appearance without damage after more than 500,000 torsions. In contrast, Comparative Example 1 showed damage after 2,000 torsions, Comparative Example 2 after 10,000 torsions, and Comparative Example 3 after 300,000 torsions. Therefore, this embodiment is significantly superior to the three comparative examples in terms of abrasion resistance and bending durability. Furthermore, after 500,000 torsions at 135 degrees, the resistance of the shielding structure 1000 of this embodiment was 0.101Ω, showing very little change compared to before the test, and still exhibiting good conductivity. Comparative Examples 1-3, however, all showed damage after 500,000 torsions at 135 degrees, resulting in open circuits; therefore, the resistance values ​​of Comparative Examples 1-3 could not be tested. Furthermore, after 500,000 twists at 135 degrees, the shielding performance of the shielding structure 1000 of this utility model embodiment is 10dB at 1GHz. However, the shielding performance of Comparative Examples 1-3 was damaged after 500,000 twists at 135 degrees, which destroyed the shielding performance of the shielding structure. Therefore, the shielding performance of Comparative Examples 1-3 could not be tested.

[0047] To improve the accuracy of the test, this utility model embodiment provides multiple sets of cable bundles for the above-mentioned torsion test, wherein each set of cable bundles has 16 cables. Figure 4 The curve shown represents the test results of the resistance values ​​of 16 cables with the shielding structure provided in this embodiment of the present invention. The horizontal axis represents the number of tests, and the vertical axis represents the resistance value of the cables. It can be clearly seen from the figure that the resistance values ​​of the 16 cables remained stable and did not change significantly during the 135-degree 500,000-cycle torsion test. The small fluctuations in the curve are due to errors in the multiple tests.

[0048] Comparative analysis of the test data from the 500,000 torsion tests at 135 degrees shows that the shielding structure 1000 of this embodiment of the invention performed normally during the test, with normal appearance and resistance values, and no open circuits were observed. In contrast, Comparative Examples 1-3 could not withstand 500,000 torsion cycles; after these tests, all exhibited damage to appearance, unmeasurable resistance values, and compromised shielding. Therefore, the shielding structure 1000 of this embodiment is significantly superior to the three comparative examples in terms of conductivity, shielding performance, abrasion resistance, and bending durability.

[0049] It should be noted that since the opening angle of the electronic product (such as a laptop) in this embodiment is usually within 135 degrees, the above test in this embodiment takes the cable twisting 135 degrees each time as an example. However, for cables used in other different occasions that require different twisting angles, the twisting angle can be adapted to other values ​​in the test. The number of cable samples in each group can also be set according to actual needs. This does not affect the superiority of this utility model embodiment over the comparative example in the test results.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
