technical field

The utility model relates to connectors, in particular to USB female connectors.

Background technique

Universal Serial Bus (USB, Universal Serial Bus) is a transmission interface initiated by Intel Corporation and Microsoft Corporation, because it can support hot plugging (that is, plug-and-play, Plug-and- Play) function, so it has become the most widely used transmission interface in personal computer peripheral products. And, so far, USB has experienced USB1.0 (low-speed mode, transfer rate of 1.5Mbps), USB1.1 (full-speed mode, transfer rate of 12Mbps) and USB2.0 (high-speed mode, transfer rate of 480Mbps) and so on. versions.

However, with the vigorous development of the electronic industry, even the high-speed transmission rate of USB2.0 is gradually difficult to meet the needs of consumers. Therefore, in order to further increase the transmission rate of USB, the USB3.0 version was launched. The transmission interface of USB3.0 is mainly based on the four-wire structure of USB2.0 (power line, ground line and two pairs of data lines), and two data output lines, two data input lines and ground lines are added to it. Among them, the newly added four data transmission lines can also transmit bidirectionally and simultaneously, so as to form the structure of the USB3.0 transmission interface through the above nine lines, so that the transmission rate of USB3.0 can reach the level of 5Gbps.

It is worth mentioning that since the development of USB, many external electronic devices of computers have adopted USB as the transmission interface due to its plug-and-play feature and increasing transmission rate. For example: external optical drive, external hard disk and external solid state disk (SSD, Solid State Disk), etc. However, when USB has been developed to version 3.0, its transfer rate has been compatible with serial high-tech configuration (SATA, Serial Advanced Technology Attachment, maximum transfer rate 1.5Gbps), external serial high-tech configuration (eSATA, External Serial Advanced Technology Attachment, Maximum transmission rate 3Gbps) and FireWire (Fireware; IEEE 1394, maximum transmission rate 3.2Gbps) and other transmission interfaces are mentioned together. Therefore, regardless of the plug-and-play convenience of USB, someone proposes the concept of transferring the USB transmission interface originally designed for external electronic devices to be used for connecting internal devices of a computer.

However, if the currently commercially available USB3.0 female connector is directly used as the USB female connector used inside the computer, unnecessary cost and configuration space of the computer motherboard will be wasted. Therefore, how to realize the application with the highest benefit in the most concise way is a subject that those skilled in the art are striving to study.
