Description

Technical Field

[0001] The utility model is applied to the technical field of communication structures, and particularly relates to a dual USB fast-charging communication module. Background Art

[0002] With the development of modern technology, USB communication is widely used in various fields that require information communication, such as automation, digital control, device communication, etc., and usually multiple sets of USB signals are applied to connect and manage various devices. In many occasions, in order to be compatible with various peripherals to meet different functions, multiple different types of interfaces may be required. In practical applications, a single input and output USB interface is sometimes difficult to meet functional requirements.

[0003] There are many types of connectors for different devices on the market, and the more common ones are USB-A and USB-C. In recent years, as users' requirements for transmission and charging speeds continue to increase, the traditional USB-A interface can only provide a maximum transmission rate of 480mpbs and a charging power of 5V / 0.5A -2.5W, which is difficult to meet user needs. However, since the USB-C interface is not compatible with all devices, sometimes the more universal USB-A is still chosen.

[0004] If a communication module solution can be provided that is compatible with interfaces of different devices and can achieve fast charging and high-speed transmission, the above-mentioned industrial application problems can be well solved. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a dual USB fast charging communication module that is compatible with interfaces of different devices and can achieve fast charging and high-speed transmission.

[0007] It can be seen from the above scheme that by setting the integrated communication line to connect the computer, the communication end is compatible with the USB-A and USB-C interfaces, and can connect the two interfaces at the same time or select one of them to connect, ensuring compatibility with the communication of different interfaces. The power supply end is connected to an external power source to provide PD high-speed charging. By integrating the type-c end, the channels of the power supply end and the communication end are integrated, thereby providing the versatility of USB-A for the working equipment, and providing the high-speed charging and high-speed data transmission functions of USB-C, thereby improving the utilization rate of the interface. The adapter port is used to achieve the expansion of the interface function.

[0008] A preferred solution is that the power supply end includes a power adapter, and the positive output end and the negative output end of the power adapter are respectively connected to the CC1 port and the VBUS port of the integrated type-c end.

[0009] A preferred solution is that the communication end includes a Top_USB line group, a Bottom_USB line group and a CC2 input line, the Top_USB line group is connected to the Top_USB port of the integrated type-c end, the Bottom_USB line group is connected to the Bottom_USB port of the integrated type-c end, and the CC2 input line is connected to the CC2 port of the integrated type-c end.

[0010] A preferred solution is that the VBUS port of the integrated port is connected to the power module of the working device and the adapter port, the Top_USB port and CC1 port of the integrated port are both connected to the adapter port, and the Bottom_USB port and CC2 port of the integrated port are both connected to the processor module of the working device.
