Background
A Universal Serial Bus (USB) interface is a standard input/output interface, and is widely used in the design of many electronic devices. In 1994, the USB association (USB-IF) was established by a union of many world-wide computer and communication companies, and the USB specification was initially established. The USB association has released versions 1.0, 1.1, 2.0, and 3.0 so far, and the aforementioned versions 1.0, 1.1, and 2.0 support the following three signal transmission rates, respectively: (1) the low-speed mode transmission rate is 1.5 Mbit per second, and the low-speed mode transmission rate is mainly used for a mouse and a keyboard; (2) a full-speed mode transmission rate of 12 megabits per second; (3) the high speed mode transmission rate is 480 megabits per second. The version 3.0 is an overspeed mode with a transmission rate of 640 megabits per second, and a plurality of electronic products adopt a USB3.0 interface at present.
The conductive terminal in the USB plug comprises a power terminal, a differential signal terminal, a grounding terminal and the like, the grounding terminal is electrically conducted with the metal shell of the USB plug, and the traditional mode is that the electric conduction is realized by weaving an outer bare grounding wire and then turning over and riveting an iron shell. This method is labor intensive, costly, and not conducive to the compact size of the USB plug.
Therefore, a connector is needed to solve the above technical problems.
