Interface Definition of USB Connector

What is Interface Definition of USB Connector？

For USB connectors, We usually divide the interface types into Type-C, Type-A, Type-B, Micro USB, Mini USB. Known as Standard A, USB Type-A was the first original design of the USB interface, with a flat and rectangular shape. It is mainly used to connect and control other USB devices like saving data on external storage devices and using mouse and keyboard.



USB Type-B is a square connector that comes in two versions. The first is USB2.0 or lower, the second is USB3.0 or higher.USB Type-B connectors are known to be used in large devices, most commonly printer devices, and since these are relatively large connectors, they are rarely seen in portable consumer devices. In addition to this, it can also be seen in data storage and acquisition, video transmission, and game hardware interfaces.The style of the Type-B interface is more robust and durable than the Type-C. Under normal circumstances, if the monitor is connected to a Type-A interface, it is most suitable to use Type-B on the other end.

USB Type C interface is a mainstream USB interface. It has a smaller volume than both Type-A and Type-B. It can be applied to both PC (master device) and external devices (slave devices, such as mobile phones). interface type. USB Type-C has 4 pairs of TX/RX split lines, 2 pairs of USBD+/D-, a pair of SBU, 2 CCs, and 4 VBUS and 4 ground wires.Its core features can be summed up in three words: "fast, strong and small". Compared with previous generations of traditional interfaces, Type-C can support charging, data transmission, image transmission and other functions at the same time, and truly realize the powerful purpose of "multi-purpose".The Type-C interface mainly has the following advantages:

1, the interface is smaller.
2. Support "positive and negative blind insertion".
3. Support fast charging and bidirectional charging.
4. Support USB3.1 standard, the maximum data transmission speed can reach 10Gbit/sec.
5. Extremely rich functional expansibility.
