What is a USB connector
It can be said that USB connectors can be seen everywhere in our daily life. We even touch electronic products every day. USB is everywhere, such as smart phones, tablets, digital cameras, mobile hard drives, printers, audio-visual equipment, multimedia, and electrical appliances. Wait, what is a USB connector?
The USB (Universal Serial Bus) connector is the USB interface, which is called Universal Serial Bus interface. It was originally used to connect the computer and its peripheral devices such as printers, monitors, scanners, mice or keyboards. Because of the fast transmission speed of the USB interface, it can It can be plugged and unplugged when power is on, and multiple devices can be connected. It has been widely used in various external devices. With the advancement of technology, the USB standard has been upgraded. In theory, the transmission speed of USB1.1 can reach 12Mbps/sec, the transmission speed of USB2.0 can reach 480Mbps/sec, and it can be backward compatible with USB1.1 and USB3.0. The transmission rate can reach up to 5.0Gbps. USB 3.1 is the latest USB specification, which is fully backward compatible with existing USB connectors and cables. The data transmission speed can be increased to 10Gbps.
At present, the most common USB interface has three standards: USB, Mini-USB, Micro-USB, Mini-USB interface is smaller than standard USB interface, suitable for small electronic devices such as mobile devices. Mini-USB is divided into Type A, Type B and Type AB. Among them, the MiniB type 5Pin interface is the most widely used interface. This interface has excellent anti-misplug performance and is relatively compact. It is widely used in card readers, MP3s, and digital cameras. And the Micro-USB connector on the mobile hard disk is a portable version of the USB 2.0 standard, which is smaller than the Mini USB interface currently used in some mobile phones. It is the next-generation specification of Mini-USB and has a blind plug structure design. Use this interface It can be used for charging, audio and data connections, and is smaller than standard USB and Mini-USB connectors, saving space, with up to 10,000 plug life and strength, and will become the mainstream interface in the future.
