This creation involves USB Type-C connectors, especially USB Type-C connector modules.

Due to the popularity of Universal Serial Bus (USB) connectors, USB connectors are deployed on almost all types of electronic devices. Through the use of these USB connectors, the user of the electronic device can easily transfer data, which is quite convenient.

The most widely used USB connector specifications are currently available in USB 2.0 specifications that support high-speed transfer rates (Hi-Speed, 480Mbps) and USB 3.0 specifications that support Super-Speed (5Gpbs). . However, with the improvement of digital data quality and file capacity, the transmission speed of the aforementioned USB2.0 specification and USB3.0 specification has gradually failed to meet the needs of existing users.

In view of this, the USB 3.1 specification has been introduced in the market, and the connector of Type-C which is more USB3.1 has received the most attention. Specifically, in addition to the above and a total of 24 terminal structures, the USB Type-C connector overcomes the problem that the conventional USB connector cannot be inserted or reversed, and can provide data transmission speed of up to 10 Gbps and output power of 100 W. .

As mentioned above, the USB Type-C connector has the convenience, high data transfer speed and large output power. In addition, the USB Type-C connector is very small and requires little space. Therefore, many new computer mainframes or electronic devices have abandoned the USB 2.0 connector and the USB 3.0 connector, and instead use the USB Type-C connector. It can be seen that the USB Type-C connector will likely become the mainstream of the new generation of common interfaces.

However, the USB Type-C connector is quite powerful, and the USB Type-C signal is more complicated than other USB format signals. Therefore, to configure the USB Type-C connector and support the USB Type-C data transmission interface. , the corresponding plurality of control chips must be set on the motherboard of the computer host or the electronic device.

However, the above control chip will occupy a valuable configuration space on the motherboard, causing a problem that the space on the motherboard is insufficient. Therefore, in the modernization with miniaturization, how to support the USB Type-C data transmission interface, the space on the motherboard is not wasted due to the setting of the control chips, and the computer host or the electronic device is not caused. The difficulty of the process and the increase of the time cost are the directions that researchers in this field are concentrating on.

The main purpose of this creation is to provide a USB Type-C connector module that integrates the USB Type-C connector with all the components needed to process the USB Type-C signal.

In order to achieve the above object, the present invention provides a USB Type-C connector module including a USB Type-C connector, a configuration channel processing unit, a multiplexer unit, and a power transmission controller unit. The power transmission control unit is connected to a power terminal of the USB Type-C connector, and the multiplexer unit is connected to a plurality of data terminals of the USB Type-C connector, and the configuration channel processing unit is connected to the USB Type-C connector. A channel terminal is configured and connected to the power transmission control unit and the multiplexer unit. When the configuration channel processing unit determines that the USB Type-C connector is connected to a specific device externally through the configuration channel terminal, the power transmission control unit outputs the corresponding size power according to the type of the specific device, and controls the multi-control The unit transmits a signal of the corresponding format.

The technical effect achieved by the creation of the related art is that the USB Type-C connector and all the components required to process the USB Type-C signal are integrated into a single module, thereby It helps the manufacturer to directly set the module on the motherboard of various electronic devices, so that various electronic devices are equipped with USB Type-C connectors and have the transmission capability of USB Type-C signals at the same time.

In addition, by adopting the USB Type-C connector module of the present invention, the configuration space of the components is not necessarily reserved on the motherboard of various electronic devices, and the manufacturer does not need to separately design circuits for the components. Thereby, the process of the electronic devices can be effectively simplified.
