Improved display 埠 connector module

This creation relates to display 埠 connectors, and more particularly to display 埠 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, although the USB connector is the mainstream specification for current data transmission, in order to transmit data of various sizes, types and frequencies in an optimal format, most existing electronic devices still have a USB connector on the motherboard. Connectors such as DisplayPort connectors and HDMI connectors for transmitting high-quality audio and video materials.

The connectors described above are not the same as the output pins of the USB Type-C connector. For example, the DisplayPort connector has 20 pins, and the HDMI connector has 19 pins. In view of this, if a manufacturer wants to simultaneously configure a USB Type-C connector, a display port (DisplayPort) connector, and an HDMI connector on an electronic device, at least three different circuits and connection pins must be reserved on the motherboard. The configuration space of the bit. As a result, the process of the motherboard will be complicated, and the cost of the motherboard cannot be reduced.

In addition, the connectors need to cooperate with the corresponding one or more processing units to process the data in the corresponding format. Therefore, if the electronic device can simultaneously support the connectors of the multiple formats, the motherboard needs to be Configure multiple processing units at the same time. As a result, the valuable configuration space on the motherboard will be seriously wasted.

The main purpose of this creation is to provide a display port connector module that integrates a display port connector and all components required to process a DisplayPort signal.

Another main purpose of the present invention is to provide a display port connector module that connects to a motherboard of an electronic device through a USB Type-C interface and requests the motherboard to output a DisplayPort signal through a USB Type-C interface.

In order to achieve the above object, the present invention provides a display port connector module including a display port connector, a first configuration channel processing unit, a second configuration channel processing unit, and a power transmission controller unit. A power terminal of the DisplayPort connector is connected to the power transmission control unit, and a detection terminal is connected to the first configuration channel processing unit. The second configuration channel processing unit is coupled to the power transmission control unit and the first configuration channel processing unit.

When the DisplayPort connector is plugged into an external DisplayPort connector male, the first configuration channel processing unit outputs a configuration channel signal to the second configuration channel processing unit, so that the second configuration channel processing unit considers that the current configuration channel is currently plugged A USB Type-C connector that conforms to the replacement mode in the USB Type-C protocol. Therefore, the second configuration channel processing unit controls the power transmission control unit to output the corresponding power, and requests the external source to output the DisplayPort signal to the DisplayPort connector.

The technical effect of this creation can be achieved by integrating the DisplayPort connector and all the components needed to process the DisplayPort signal into a single connector module, which helps the manufacturer to connect the connector module. It is directly installed on the motherboard of various electronic devices, so that various electronic devices are equipped with a DisplayPort connector and have the transmission capability of DisplayPort signals at the same time. Moreover, the configuration space of the components does not have to be reserved on the motherboard, and the manufacturer does not need to additionally design circuits for the components. Thereby, the process of the electronic devices can be effectively simplified.

In addition, the connector module mainly communicates with the motherboard through the USB Type-C interface, and when the external DisplayPort connector male connector is plugged, the motherboard is considered to be currently compatible with the USB Type. A USB Type-C connector male in the replacement mode of the -C protocol, which in turn outputs the DisplayPort signal. In this way, the connector module can use the same pin position on the motherboard as a general USB Type-C connector, and the manufacturer does not need to additionally set the connector on the motherboard. The module-specific circuits and connection pins can effectively simplify the manufacturing process of the electronic devices and reduce the cost of the motherboard.
