Description

usb connector

technical field

The present invention relates to a universal serial bus (Universal Serial Bus, USB) connector, in particular to a USB connector with a detachable USB plug.

Background technique

USB is the most widely used peripheral bus in the computer industry and consumer electronics industry today. The Universal Serial Bus can be used to connect various peripheral devices, such as keyboards, mice, U disks, card readers, digital cameras, personal digital assistants, Smartphones and more. Plug and play and ease of use are also the biggest factors that cause the popularity of USB in the market. Nowadays, both peripheral manufacturers and computer manufacturers have developed a lot of applications for USB, and various drivers and applications are also available. all available.

Currently, the data transfer rate of USB 2.0 is 480Mbps, while USB 3.0 can reach 5Gbps, which is 10 times faster than USB 2.0. Compared with USB 2.0, USB 3.0 will be more power efficient. Additionally, USB 3.0 is backward compatible to support USB 2.0 devices. Please refer to Table 1 below, which shows the correspondence between various USB 2.0/3.0 plugs and sockets.

Table 1

As shown in Table 1, in type 3, the socket of USB 2.0 standard B terminal can only be used to connect the plug of USB 2.0 standard B terminal; in type 6, the socket of USB 2.0 micro B terminal can only be used to connect USB 2.0 micro-B plug; in type 8, the USB 2.0 micro-AB receptacle can only be used to connect a USB 2.0 micro-B or USB 2.0 micro-A plug.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of a traditional USB 3.0 standard B-terminal connector 1 . As shown in FIG. 1 , the USB 3.0 standard B-terminal connector 1 includes a USB 2.0 standard B-terminal plug 10 and a standard B-terminal plug 12 . In the prior art, since the USB 2.0 standard B-terminal plug 10 is inseparably connected with the standard B-terminal plug 12, if the electronic device only has a USB 2.0 standard B-terminal socket, the USB 3.0 standard B-terminal connector 1, it cannot be plugged into a USB 2.0 standard B-terminal socket for data transfer or charging.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram of a conventional USB 3.0 micro-A terminal connector 2 . As shown in FIG. 2 , the USB 3.0 micro-A terminal connector 2 includes a USB 2.0 micro-A terminal plug 20 and a micro-A terminal plug 22 . In the prior art, since the USB 2.0 micro-A terminal plug 20 and the micro-A terminal plug 22 are inseparably connected together, if the electronic device only has a USB2.0 micro-AB terminal socket, the USB 3.0 micro-A terminal connector 2 cannot Plug into the USB 2.0 micro AB terminal socket for data transfer or charging.

Please refer to FIG. 3 , which is a schematic diagram of a traditional USB 3.0 micro-B terminal connector 3 . As shown in FIG. 3 , the USB 3.0 micro-B terminal connector 3 includes a USB 2.0 micro-B terminal plug 30 and a micro-B terminal plug 32 .
