A USB connector is a safe and energy-saving universal connector with a USB interface. The USB connector is only connected to the circuit when power is needed. This not only has the advantages of charging low-voltage electrical appliances by simply connecting them with the USB socket on the universal switch using a USB plug cable, but also has the advantages of preventing the device from being connected to the power for a long time, extending the device's lifespan, saving electricity, and eliminating hidden dangers.

The USB 3.0 connector is a pointer to the USB 3.0 standard USB connector. The appearance of the USB 3.0 connector cable is similar to that of Class 5 network cables, and the interface is divided into two parts: A and B. Part A is compatible with the USB 2.0 we are currently using, and Part B is an extended interface from USB 3.0.

The physical interface scale of the USB 3.0 connector is the same as that of the USB 2.0 connector, but in order to improve transmission speed, four pins were added to reach nine instead of the original five. Therefore, new hardware is necessary to support it. USB 3.0 and USB 2.0 are compatible with each other, which means that USB 2.0 devices plugged into USB 3.0 ports or USB 3.0 devices plugged into USB 2.0 ports can operate normally, but can only reach USB 2.0 transmission speed.

一、USB 3.0 connector performance and features

1. The data bandwidth of USB 3.0 is ten times that of USB 2.0, reaching 5Gb/s (480MB/s), and the synchronous transmission bandwidth can also reach 384MB/s.

2. Low power consumption (approximately 25% lower than USB 2.0 at a data transfer rate of 20MB/s).

3. For devices that are temporarily in a waiting state, power saving mode can be used.

4. Being able to provide greater power through cables (from 2.5W to 4.5W) can reduce the charging time of the appliance. Plug in USB connector directly.

二、Application of USB 3.0 connectors

Now, some new mid to high end motherboards support USB 3.0, usually completed with third-party chips, and these USB 3.0 interfaces are only located on the motherboard, which means facing towards the rear of the computer. Currently, there is no motherboard to support the front USB 3.0 interface of the external chassis. Moreover, there are very few chassis with front-end USB 3.0 interfaces nowadays, and the price is very high. Technically speaking, adding a front-end USB 3.0 interface to the motherboard and chassis should be a simple task with low cost. But now, if we reach the level of popularization, it may take a long time.
