USB interface is a Universal Serial Bus, which is a Universal Serial Bus. USB connectors are always used to connect and communicate with external devices. Like in our daily life to charge mobile phones, computers will use USB interface connector, so often used, THE size of USB interface connector is not the same, different interfaces connected to different products. So what’s the difference between the different USB connectors?
USB interface connectors, also known as universal connectors, are generally divided into type A, B and C, usually referred to as type A.
1. Type A rectangle is generally used in personal computers, mainly connecting mobile phones, wireless network cards, U disks, mobile CD drives, small capacity mobile hard disks, etc., which are most widely used.
2, Type B is generally used for 3.5-inch mobile hard disk, printer, and monitor connection.
3, Type C Type A and B upgraded version, oval, with support for positive and negative symmetry plug (regardless of both sides can be inserted), support more power transmission and bidirectional power transmission, thin interface features, and set charging, display, data transmission and other functions in one. The size is about 8.3mm x 2.5mm. It is mainly used for thinner and slimmer devices such as smart phones (the interface of mobile phones and tablets may be unified in the future, instead of Micro USB interface). As a popular new standard interface in recent years, it is more and more widely used because of its support for positive and negative insertion and many optional functions.
With the continuous iteration of USB, Type-C gradually tends to replace Type-A and B. As early as 2014, USBType-C was launched. At the end of the year, it was first applied to the Nokia N1 tablet. Early 2015 app on Google Chromebook Pixel; Later, Apple, Google and Asustek introduced laptops equipped with USB-C connectors, which started usB-C’s promotion in the 3C space. At present, Huawei, ZTE, Xiaomi, Lenovo and OPPO have basically launched products equipped with USB-C.
Advantages of Type-C:
1. Compared with the traditional USB interface, the type-C interface has the same front and back shapes, so that no matter how you insert it into the interface, it will not be wrong. Slender interface, simple interface, reduce the failure rate.
2. Compared with other A/B interfaces, Type-C has no Mini/Micro, and all interface shapes are unified with strong versatility.
3. Under different bandwidths and definitions, traditional USB interfaces have different appearance due to the needs of pins. The type-c interface has the same shape regardless of USB2.0 speed or 3.0 speed.
