[0029] First Embodiment
[0030] like Figures 1-5 As shown, a transmission cable with a PCB includes a flexible flat cable 1, a first PCB board 2, and a first connector 3. The flexible flat cable 1 includes multiple conductors 4, an insulation layer 5, and a shielding layer 6. The multiple conductors 4 are spaced apart within the insulation layer 5, and one end of each conductor 4 protrudes beyond the outer side of the insulation layer 5. The shielding layer 6 is disposed on the outer periphery of the insulation layer 5, and the conductors 4 protrude beyond the outer side of the insulation layer 5. The first PCB board 2 has a first conductive part 7 and a second conductive part 8 at both ends, respectively. One end of each conductor 4 is connected to the first conductive part 7, and the first connector 3 is connected to the second conductive part 8.
[0031] This invention connects conductor 4 directly to the conductive parts on the PCB board, avoiding the process of individually arranging and soldering each conductor as in traditional round cables. This reduces the need for manual operation, improves soldering consistency and quality, and reduces the uncertainty caused by manual soldering. Due to its innovative structural design, this flat cable can be soldered using automated equipment, significantly improving production efficiency while reducing manufacturing costs and technical difficulty. Compared to traditional round cables, this flat cable, through its unique structural design, provides better mechanical strength and resistance to external physical damage such as bending and stretching, increasing cable durability. The flat cable design allows for easier wiring in confined spaces and occupies less space, a significant advantage for electronic devices with limited internal space.
[0032] This embodiment describes a transmission cable with a PCB. The first conductive part 7 includes multiple pads 9, which are spaced apart at one end of the PCB. The conductors 4 are soldered one by one onto the pads 9. Specifically, the first conductive part 7 includes multiple pads 9, and each conductor 4 is correspondingly soldered onto these pads 9, ensuring that each conductor can be accurately connected to the PCB, thereby guaranteeing the stability and accuracy of signal transmission.
[0033] In this embodiment, a transmission cable with a PCB is described, wherein the spacing between any two adjacent pads 9 is the same, and the spacing between any two adjacent conductors 4 is also the same. Specifically, by maintaining the same spacing between adjacent pads 9 and conductors 4, a more uniform signal distribution can be achieved, reducing signal interference.
[0034] This embodiment describes a transmission cable with a PCB, comprising a second PCB board 10 and a second connector 11. The other ends of the conductors 4 protrude from both ends of the insulating layer 5. The second PCB board 10 has a third conductive portion 12 and a fourth conductive portion 13 respectively at both ends. The other end of the conductor 4 is connected to the third conductive portion 12, and the second connector 11 is connected to the fourth conductive portion 13. Specifically, the addition of the second PCB board 10 and the second connector 11 enables electrical connection at both ends of the flat cable, enhancing its functionality and applicability, making it suitable for applications requiring bidirectional data transmission.
[0035] This embodiment describes a transmission cable with a PCB. Both ends of the shielding layer 6 have laser-etched windows 14. The first PCB board 2 and the second PCB board 10 have grounding conductive portions 15 on their sides facing the shielding layer 6. The laser-etched windows 14 and the grounding conductive portions 15 are correspondingly arranged. Specifically, the arrangement of the laser-etched windows 14 and the grounding conductive portions 15 allows the shielding layer 6 to be effectively grounded, thereby further enhancing the shielding effect, reducing external electromagnetic interference, and ensuring the purity and integrity of internal signals.
[0036] This embodiment describes a transmission cable with a PCB, comprising a first insulating shell 16 and a second insulating shell 17. The first PCB board 2 is disposed within the first insulating shell 16, and the second PCB board 10 is disposed within the second insulating shell 17. The two ends of the flexible flat cable 1 extend into the first insulating shell 16 and the second insulating shell 17, respectively. The first connector 3 is connected to the first insulating shell 16, and the second connector 11 is connected to the second insulating shell 17. Specifically, using an insulating shell to house the PCB board not only protects sensitive electronic components from external environmental influences but also simplifies the assembly process between the cable and the equipment, improving installation efficiency.
[0037] This embodiment describes a transmission cable with a PCB, wherein the first PCB board 2 is L-shaped. Specifically, the L-shaped first PCB board 2 can better adapt to installation spaces of different shapes and sizes, increasing the flexibility of the cable and making it easier to integrate into products with compact or specific geometries.
[0038] This embodiment describes a transmission cable with a PCB, in which the shielding layer 6 surrounds the outer periphery of the insulation layer 5. Specifically, the design of the shielding layer 6 surrounding the insulation layer 5 provides all-around electromagnetic shielding for the cable, effectively preventing interference from external electromagnetic waves and also preventing internal signal leakage, thereby improving the quality of signal transmission.
[0039] Second Embodiment
[0040] like Figure 6 As shown, the difference between this embodiment and the first embodiment is that the shielding layer 6 is provided at both the upper and lower ends of the insulating layer 5. Specifically, the above-mentioned arrangement facilitates processing.
