[0015] EMBODIMENT

[0016] In order to solve the above technical problems, the present application provides an LVDS optical and electrical hybrid cable, as shown in Figure 1As shown, the cable includes a filler 10, a four-core optical fiber cable 20, a plurality of low-speed signal lines 30, a plurality of power supply lines 40 and a plurality of electronic lines 50, and a shielding layer 60, a braided layer 70 and an outer sheath layer 80 which are sequentially wrapped from the inside to the outside of the outer periphery. The filler 10 is located at the center, and the four-core optical fiber cable 20, the low-speed signal line 30, the power supply line 40 and the electronic line 50 are wrapped around the outer periphery of the filler 10. By replacing the existing four groups of high-speed signal line pairs with the four-core optical fiber cable 20, the maximum transmission speed of each core optical fiber can reach more than 10 Gbps, and the use length can reach more than 100 m. Moreover, the overall outer diameter size of the four-core optical fiber cable 20 is only 20% of the outer diameter size of the traditional four groups of high-speed signal line pairs. The transmission speed is greatly improved while the diameter is reduced, and the performance requirements of customers for high-speed data transmission are met. At the same time, the four-core optical fiber cable 20 is designed to be located at the outer circle of the cable core, thereby reducing the influence of the internal stress generated by the cable twisting on the four-core optical fiber cable 20, and ensuring the high-speed transmission performance of data.

[0017] Specifically, the low-speed signal line 30 is provided with two, and the four-core optical fiber cable 20 is located between the two low-speed signal lines 30 and the filler 10. Among them, the low-speed signal line 30 adopts a shielded differential signal line pair, and can realize a point-to-point or a point-to-multipoint connection mode. The transmission medium can be a copper PCB connection line or a balanced cable. The four-core optical fiber cable 20 abuts against the shielding layer 60 and is located between the two low-speed signal lines 30 and the filler 10, so that the four-core optical fiber cable 20 is located at the outer circle position of the overall cable core, thereby reducing the influence of the internal stress generated by the cable twisting on the four-core optical fiber cable 20, and ensuring the high-speed transmission performance of the four-core optical fiber cable 20.

[0018] Further, the electronic line 50 is provided with two, and the two electronic lines 50 are respectively located on both sides of the four-core optical fiber cable 20. The power supply line 40 is provided with three, and the power supply line 40 is located on the side of the filler 10 away from the four-core optical fiber cable 20.

[0019] In the above scheme, the electronic line 50 includes a first conductor 51 and a first FEP insulating layer 52 wrapped around the first conductor 51. The power supply line 40 includes a second conductor 41 and a second FEP insulating layer 42 wrapped around the second conductor 41. The three power supply lines 40 are connected in parallel to realize fast charging power supply, and the insulations of the electronic line 50 and the power supply line 40 are both FEP insulating layers which are resistant to high temperature, thereby meeting the requirement of high temperature resistance when the power supply line 40 is fast charging.

[0020] Further, the shielding layer 60 is made of aluminum foil, and the braiding layer 70 is made of copper wire braiding, and the braiding density is greater than 90%, which can meet the EMI shielding requirements in complex electromagnetic environment. The outer layer 80 is made of TPU outer sheath material with excellent mechanical properties, which can well protect the optical fiber and wires in the cable when the cable is used outside the electronic equipment, and ensure data transmission and power transmission.

[0021] In summary, the present application is provided by setting the filler, four-core optical fiber, low-speed signal line, power line and electronic line, and the shielding layer, braiding layer and outer layer which are sequentially coated from the inside to the outside of the outer periphery. The filler is located in the center, and the four-core optical fiber, low-speed signal line, power line and electronic line are surrounded by the outer periphery of the filler. The maximum transmission speed of each core optical fiber can reach more than 10Gbps by using four-core optical fiber instead of the existing four groups of high-speed signal line pairs, and the use length can reach more than 100m. Moreover, the overall outer diameter size of the four-core optical fiber is only 20% of the outer diameter size of the traditional four groups of high-speed signal line pairs. The transmission speed is greatly improved while reducing the wire diameter, which meets the performance requirements of customers for high-speed data transmission. At the same time, the position of the four-core optical fiber is designed at the outer circle of the cable core, which reduces the influence of the internal stress generated by the cable twisting on the four-core optical fiber, thereby reducing the influence on the performance of the four-core optical fiber and ensuring the high-speed data transmission performance.

[0022] The above-described embodiments do not constitute a limitation on the protection scope of the technical solution. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the above-described embodiments should be included in the protection scope of the technical solution.
