The USB interface is a connecting cable that everyone uses in their daily work and life. USB is an English abbreviation, and its original meaning is: Universal Serial Bus, which means Universal Serial Bus. USB connectors are always used for connecting and communicating between computers and external devices. In our daily lives, we often use USB interface connectors to charge mobile phones and connect computers to the internet. As we all know, the size of USB interface connectors varies, and different interfaces connect different products. So do you know what the differences are between these different USB interface connectors?

USB interface connectors, also known as universal interfaces, are generally divided into Type A, Type B, and Type C, commonly referred to as Type A.

1. The type-a rectangle is generally used in personal computers, mainly to connect mobile phones, Wireless network interface controller, U disks, mobile optical drives, small capacity Portable storage device, etc., and is the most widely used.

2. Type-b is generally used for the connection of 3.5-inch Portable storage device, printer, display device, etc.

3. The upgraded versions of type-c type-a and b are oval shaped, with support for symmetrical insertion and insertion of both sides (both sides can be inserted), support for higher power transmission and bidirectional power transmission, and have thin interfaces. They also integrate functions such as charging, display, and data transmission. Approximately 8.3mm in size × 2.5mm. Mainly targeting lighter, thinner, and slimmer devices such as smartphones (in the future, it may unify the interface of mobile tablets to replace the micro USB interface). It is a new standard interface that has become increasingly popular in recent years due to its support for forward and reverse insertion and multiple optional functions.

With the continuous replacement of USB, there is a trend for type-c to replace Type-A and B. As early as 2014, USB type-c was introduced. At the end of the year, it was first applied to the Nokia N1 tablet; Applied in Google Chrome Pixel in early 2015; Subsequently, Apple, Google, and Asus successively launched laptops equipped with USB C connectors, opening up the promotion of USB C interfaces in the 3C field. At present, manufacturers such as Huawei, ZTE, Xiaomi, Lenovo, and OPPO have all launched products equipped with USB C.

What are the advantages of type-c:

Compared with traditional USB interfaces, Type-C has a completely identical interface form on both sides, so no matter how it is inserted into the interface, it will not be inserted incorrectly. Slender interface, simpler interface, reduces failure rate.

Compared to other A/B interfaces, type-c does not have the distinction of Mini/Micro, and all interface shapes are unified and highly versatile.

3. Under different bandwidths and definitions, traditional USB interfaces may exhibit different appearance shapes due to pin requirements. The type-c interface, on the other hand, remains unchanged in shape regardless of whether the USB 2.0 speed is still 3.0.
