[0001] This utility model relates to the field of TYPE-C bonded high-frequency line technology, and in particular to a highly stable TYPE-C bonded high-frequency line. Background Technology

[0002] In today's rapidly developing digital and intelligent world, the demand for high-speed data transmission and stable power supply between electronic devices is growing. The TYPE-C interface, with its advantages of being small and portable, supporting reversible plugging and unplugging, high transmission rate and strong power transmission capability, has become the mainstream interface for devices such as smartphones, tablets and laptops. The application of high-frequency cables further improves the speed and quality of signal transmission. The combination of the two is widely used in scenarios such as high-definition video transmission, high-speed data download, and fast charging, and is a key component for achieving efficient interconnection of devices.

[0003] Existing TYPE-C combined with high-frequency cable products mostly use standard TYPE-C plugs for the interface, which are connected to the internal circuitry through simple pin soldering. For signal transmission lines, ordinary PCB boards or single-layer FPC cables are commonly used.

[0004] However, existing TYPE-C cables suffer from significant signal interference and unstable transmission during high-frequency signal transmission. Furthermore, in terms of mechanical structure, the plug shell lacks sufficient compressive strength, making it prone to deformation after welding, which affects the reliability of the connection. During bending, the internal wiring can easily separate from the outer mold, leading to cable damage. Therefore, a highly stable TYPE-C combined with high-frequency cable is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a highly stable TYPE-C high-frequency cable, which aims to improve the problems of large signal interference and unstable transmission in the existing TYPE-C cable during high-frequency signal transmission.

[0013] The FPC flexible reinforcing plate has a thickness of 0.1 mm and its edges are rounded with a radius of 0.2 mm.

[0014] As a further description of the above technical solution:

[0015] The dielectric constant of the FPC flexible bus insulation layer is 3.2, the thickness is 0.025 mm, and an antistatic coating is provided on its surface.

Its line is connected to the corresponding line on the high-frequency PCB four-layer board 3 to ensure stable signal transmission from the PCB board to downstream equipment. The line on the FPC signal line 4 is connected to the corresponding line on the high-frequency PCB four-layer board 3. An FPC flexible busbar reinforcing plate 5 is provided on the outer wall of the FPC signal line 4. An FPC flexible busbar insulating layer 6 is provided on the outer wall of the FPC signal line 4. The edge of the FPC flexible busbar insulating layer 6 is attached to the edge of the FPC flexible busbar reinforcing plate 5. The thickness of the FPC flexible busbar reinforcing plate 5 is... The dielectric constant of the FPC flexible bus insulation layer 6 is 3.2, and its thickness is 0.025mm. The surface of the insulation layer 6 is coated with an anti-static coating.

[0027] Working Principle: In terms of signal transmission, this TYPE-C connector, combined with a high-frequency cable, firstly provides a reliable interface foundation for signal transmission by selecting a 24P / 22P full-function protocol TID certified TYPE-C connector 1. TYPE-C connector 1 serves as the interface for connecting to external devices, and its signal pins are connected to the corresponding lines on the high-frequency PCB 4 layer 3. When an external device transmits a signal, the signal is transmitted to the high-frequency PCB 4 layer 3 through the pins of TYPE-C connector 1. The high-frequency PCB 4 layer 3 has a multi-layer structure including a signal top layer, ground layer, and power layer, which can rationally plan and transmit the incoming signal. The signal is transmitted from the high-frequency PCB 4 layer 3 to the FPC signal line 4. The lines on the FPC signal line 4 are connected to the corresponding lines on the high-frequency PCB 4 layer 3, continuing to carry the signal transmission. The FPC flexible busbar insulation layer 6 covers the lines of the FPC signal line 4. Its low dielectric constant and surface anti-static coating further reduce interference during signal transmission, ensuring stable and fast transmission of high-frequency signals.

Its clamping feet are connected to the high-frequency PCB 4 layer 3 and electrically connected to its ground plane, reducing ground impedance and enhancing high-frequency stability. The FPC flexible strip reinforcing plate 5 is installed on the outer wall of the FPC signal line 4. Its 0.1mm thickness and rounded corners increase the strength of the FPC signal line 4 without compromising flexibility, preventing damage during bending. The chip 7 inside the high-frequency PCB 4 layer 3 has its power input connected to the power plane and its signal input connected to the signal top plane, allowing for signal processing and conversion according to different application requirements, enabling high-speed signal transmission and specific power charging output.
