[0019] As Figure 1-2 shown, a USB data cable structure capable of long-distance stable transmission includes a cable 10, and one or both ends of the cable 10 are connected to a USB connection port 20; more than one amplifier 30 is connected in series at intervals on the cable 10, and a charging member 40 is provided on each amplifier 30.

[0020] The utility model sets a number of amplifiers 30 between cables 10 and externally connects a charging member 40 to each amplifier 30, which can ensure that the amplifier 30 can continuously amplify the electrical signal or optical signal passing through the cable 10 to offset the signal attenuation caused by long-distance transmission, improve the accuracy of signal transmission of the signal line, and meet the usage requirements of long-distance signal transmission connection; by setting USB connection ports 20 at one end or both ends of the cable 10, the data cable has strong compatibility, can meet the connection requirements of most devices and products, and has a wide range of applicability.

[0021] Further, each amplifier 30 includes an insulating housing 31 and an inner core. Each inner core includes a circuit board 32 equipped with a chip and a resistor. Each circuit board 32 is electrically connected to the core wire inside the cable 10. Both ends of each insulating housing 31 are fixedly connected to the outer sheath of the cable 10 respectively.

[0022] Further, each insulating housing 31 includes an upper cover and a lower cover that are hinged or detachably fixed. The circuit board 32 is detachably fixed on the upper cover or the lower cover.

[0023] Further, each charging member 40 is a wired charging member or a wireless charging member: each wired charging member includes a charging port 33 provided on and electrically connected to the circuit board 32, and each insulating housing 31 is provided with an avoidance hole groove adapted to the charging port 33; each wireless charging member includes a receiver provided on the circuit board 32.

[0024] It can be understood that the structure of the movable insulating housing 31 facilitates the disassembly, assembly and maintenance of the inner core safely and quickly; the setting of the charging member 40 can ensure that the amplifier 30 can always be in a normal working state when needed.

[0025] Further, an input identification member 50 and / or an output identification member 60 are respectively provided at one end or both ends of the cable 10.

[0026] It can be understood that the setting of the input identification member 50 and the output identification member 60 can remind the user not to connect the cable 10 reversely and ensure the normal operation of the amplifier 30 therein.

[0027] Further, a number of amplifiers 30 are connected in series at equal intervals on the cable 10. The distance d1 between two adjacent amplifiers 30 is between 2m and 9m, and the distance d2 between the USB connection port 20 and its adjacent amplifier 30 is less than 9m.

[0028] It can be understood that the limitation of the distance d1 between two adjacent amplifiers 30 can control the signal attenuation within a certain range, thereby ensuring the accuracy of signal transmission and meeting the signal transmission requirements of different connection ports.

[0029] In this embodiment, the length of the cable 10 can reach 30 m, and USB connection ports 20 are connected to both ends. The distance d1 between two adjacent amplifiers 30 is 7.5 m, the distance d2 between one amplifier 30 at one end and one USB connection port 20 is 7.5 m, and the distance d2 between the amplifier 30 at the other end and the other USB connection port 20 is 0.3 m. Additionally, according to different usage scenarios, when the length of the cable 10 is between 5 - 12 m, one amplifier 30 can be placed at the middle position; when the length of the cable 10 is between 12 - 15 m, two amplifiers 30 can be evenly placed; when the length of the cable 10 is between 15 - 20 m, three amplifiers 30 can be evenly placed; when the length of the cable 10 does not exceed 30 m, four amplifiers 30 can be evenly placed. In application, the appropriate length of the cable 10 and the number of amplifiers 30 can be selected according to actual needs.

The USB connection port 20 can be set as a male or female interface to meet the connection needs between different devices and electrical products, with wide applicability.

[0031] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
