Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] Please refer to the attached Figure 1 The utility model provides a USB data cable, including a male connector J1 and a processing circuit connected to the male connector J1, wherein the processing circuit includes a main control chip U3, a power supply module 11 and a wireless transmission module 12, wherein the power supply module 11 is connected between the main control chip U3 and the male connector J1, and the wireless transmission module 12 is electrically connected to the main control chip U3;

[0034] The wireless transmitter module 12 is integrated with the male connector J1. Preferably, the wireless transmitter module 12 is a 2.4G Dongle transmitter module. The male connector J1 is provided with a first VBUS terminal VBUS and a first DC positive and negative terminal. Through this setting, the power supply module 11 can be guaranteed to supply power to the product equipment smoothly.

[0035] Specifically, the male connector J1 can be connected to the TYPE-C female connector on a computer or mobile phone for power supply and data communication.

[0037] Please refer to the attached Figure 2 The wireless transmitting module 12 includes an antenna matching element 121 and a first radio frequency terminal ANT. The antenna matching element 121 is electrically connected to the main control chip U3.

[0039] Please refer to the attached Figure 4 The power supply module 11 includes a filtering element 111 and a connecting element 112.

[0041] The first VBUS terminal VBUS is a voltage bus in the USB interface, and the first radio frequency terminal ANT is a radio frequency current, that is, a high-frequency alternating current changing electromagnetic wave.

[0042] In this structure, the USB data cable 1 can be used to charge the product device, and can also transmit signals for the transmitter of the wireless product. Specifically, the connection with the product device is matched through the first VBUS terminal VBUS and the first DC positive and negative terminals (D+, D-) for data transmission, so as to complete the communication and charging functions with the product device.
