USB Connector 2.0/3.0 Product Introduction

USB, short for Universal Serial Bus, is an industry standard developed in the mid-1990s that defines the cables, connectors and communications protocols used in a bus for connection, communication, and power supply between computersand electronic devices.It is currently developed by the USB Implementers Forum (USB IF).It mainly has three series ,usb2.0/3.0/3.1,connector type has A type,B type, Mini A/B,Micro usb connector A/B ,C type.Above all Mini type is seldom used.

USB was designed to standardize the connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adapters) to personal computers, both to communicate and to supply electric power. It has become commonplace on other devices, such as smartphones, PDAs and video game consoles,psp usb cables,etc. USB has effectively replaced a variety of earlier interfaces, such as parallel ports, as well as separatepower chargers for portable devices.

The newly type c usb connectors,are designed to an industry standard that provides a sleek,slim design small enough for handheld devices and robust enough for industrial applications.The USB Type-C connector features reversible mating interface; the receptacle is designed to accept a plug in any direction, enabling easy, reliable mating. This connector supports a variety of diff erent protocols, and with the use of adaptors, it is backwards compatible to HDMI, VGA, DisplayPort, and other types of connections from the single USB Type-C port. We provide a distinctive electromagnetic interference (EMI) design on the back of the receptacle shell to help eliminate unwanted EMI leakage, as well as enhanced retention features, waterproof and splash proof options for better performance in rugged environments.

USB type A connector usually used in perconal computers,it’s the most widely used usb connectors.
USB type B connectors usually used for 3.5inch Mobile HD,printer machine and displayer.
Mini USB usually used for digital camera,digital video,Measuring instrument and disk enclosure.
Micro USB is the most common usb connector which is widely used in our mobilephone connectors.
