[0002] With the rapid development of technologies such as 5G, cloud computing, and big data, modern electronic devices are increasingly demanding higher efficiency in data transmission and charging. The Type-C interface, with its compact size, portability, and reversible plugging capabilities, is gradually becoming the mainstream connection method for smart terminals, laptops, monitors, and other devices. Against this backdrop, developing high-frequency Type-C cables capable of achieving high-speed data transmission and efficient charging has become a key technological direction for meeting market demands and improving the user experience.

[0003] Currently, most commercially available Type-C data cables use a basic physical interface and simple circuit design. For data transmission, they rely on traditional wiring layouts, and for charging, they deliver power through conventional power lines. While this design meets the basic connection and power needs of devices, it has certain limitations in performance.

[0004] However, existing Type-C cables either have low data transfer rates, failing to meet the demands of scenarios such as 4K / 8K video transmission and rapid copying of large files; or they have limited charging power, unable to provide fast charging for high-power devices. Incompatibility issues with the interface protocols of different devices also make it difficult for these cables to flexibly adapt to various application scenarios in practical use, thus limiting the user experience.

[0012] Furthermore, the 0-ohm resistor enables 10GB signal rate transmission and 60W charging power output on the same FPC board.

[0013] Furthermore, the FPC flexible board is made of a flexible material with high high-frequency transmission characteristics (ultra-thin PET high-frequency material), with double GND and VBUS4 separately arranged on the front side.

[0014] Furthermore, multiple FPC board vias are arranged in a linear array inside the FPC flexible board.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3 One embodiment of this utility model is a high-speed transmission TYPE-C high-frequency cable, comprising:

[0027] FPC flexible board 4, with multiple FPC board vias 5 inside, both ends of which are connected to TYPE-C plug 1 through FPC board gold fingers 6;

[0028] FPC board gold fingers 6, one end of each of the two FPC board gold fingers 6 is set inside the TYPE-C plug 1, and the other end is fixedly connected to the FPC flexible board 4;

[0029] EMARKERIC2 is installed inside the FPC flexible board 4;

[0030] 0-ohm resistor 3 is installed inside the FPC flexible board 4. EMARKERIC2 enables 10GB / 20GB / 40GB signal rate transmission and 100W / 240W ultra-high charging power output. 0-ohm resistor 3 enables 10GB signal rate transmission and 60W charging power output for the same FPC board. The FPC flexible board 4 is made of ultra-thin PET high-frequency material with high high-frequency transmission characteristics. Double GND and VBUS 4 are individually arranged on the front side. Multiple FPC board vias 5 are linearly arrayed inside the FPC flexible board 4. The two FPC board gold fingers 6 are coated with adhesive on both sides. The adhesive is conductive epoxy resin with a thickness ≥0.1mm. The back side of the FPC flexible board 4 contains signal P and BVBUSP.

[0031] Specifically, the TYPE-C high-frequency cable, through the adoption of a 24P / 22P full-function TID certified TYPE-C plug 1 and the built-in EMARKERIC2 communication protocol, can automatically identify and negotiate data transmission rates up to 40Gbps and charging power up to 240W, meeting users' needs for high-speed data transmission and high-power charging. The 0-ohm resistor 3 in the circuit provides a basic 10Gbps / 60W option, offering flexible solutions for different usage scenarios and greatly improving the product's versatility and practicality. In terms of structural design and reliability assurance, this patent effectively improves product reliability through innovative circuit and structural design. The FPC flexible board 4, made of ultra-thin PET high-frequency material, features a unique wiring scheme. The front of the FPC flexible board 4 has double GND and widened VBUS traces with a width ≥0.3mm, effectively reducing line impedance (≤50mΩ). The reverse side features precision differential signal lines with a line width / spacing of 0.1mm / 0.1mm, ensuring high-frequency signal integrity. A high-density via array 5 (hole diameter ≤0.2mm, spacing ≤0.5mm) in the middle of the FPC flexible board 4 not only enhances the electrical connection between the inner and outer conductors but also significantly improves the board's bending resistance, allowing it to withstand over 3000 swing tests. The FPC gold fingers 6 at both ends of the FPC flexible board 4 employ a four-point adhesive reinforcement design (conductive epoxy resin, thickness ≥0.1mm), combined with a high-precision assembly process of ±0.15mm, effectively resisting mechanical stress during injection molding, ensuring connection stability and overall product reliability, and extending product lifespan.

[0032] Working Principle: This high-speed transmission TYPE-C high-frequency cable uses a 24P / 22P full-function TID certified TYPE-C plug 1 as its physical interface. Internally, it integrates the EMARKERIC2 communication protocol to interact with connected devices, automatically identifying and negotiating a data transmission rate of up to 40Gbps and a charging power of 240W. In terms of circuit design, the FPC flexible board 4, made of ultra-thin PET high-frequency material, achieves signal optimization through a unique wiring scheme: double GND and widened VBUS traces (width ≥ 0.3mm) are separately arranged on the front to reduce impedance (≤ 50mΩ), while precision differential signal lines (line width / spacing 0.1mm / 0.1mm) are arranged on the back to ensure high-frequency signal integrity.

[0033] Furthermore, to enhance structural reliability, a high-density via array 5 (hole diameter ≤ 0.2mm, spacing ≤ 0.5mm) is installed in the middle of the FPC board. This strengthens the electrical connection between the inner and outer conductors and improves the board's bending resistance, allowing it to withstand over 3000 swing tests. The gold fingers 6 at both ends of the FPC board employ a 4-point adhesive reinforcement design (conductive epoxy resin, thickness ≥ 0.1mm), combined with a high-precision assembly process of ±0.15mm, ensuring connection stability. Simultaneously, the 0-ohm resistor 3 in the circuit provides a basic 10Gbps / 60W functional option, offering flexible solutions for different needs, effectively resisting mechanical stress during injection molding, and ensuring overall product reliability.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
