Description
[technical field]
The invention belongs to a kind of connector, especially refer to a kind of high speed plug connector, it sees through length and the volume that the suitable configuration of welding section is reduced to pin connector integral body, and then makes pin connector can be widely used in all types of circuit boards.
[prior art]
Current YouUSB (the USB Implementer Forum Inc. of association, USB-IF) USB 2.0 host-host protocols of formulating are basic specifications of USB connector, ErUSB association be near completion there is high transmission speed more USB3.0 host-host protocol to deal with day by day huge transfer of data demand.USB3.0 connector, except can backward compatible USB2.0 connector, more can provide the high-speed transfer operation up to 5Gbps, under this transmission standard, can allow the device or the adapter that in more script palpuses, are built in computer to become circumscribed peripheral unit.
Yet, because having two row terminals, USB3.0 connector carries out the host-host protocol of USB2.0 and 3.0, not only volume is large for it, complex structure and cause the problems such as mould development cost is high, assembling difficulty, more easily because interfering with each other between high-frequency signals transmission terminal causes signal transmission failure.In addition, when being connected with circuit board, compared to USB2.0 connector, two row welding sections of USB3.0 bonder terminal take the more area of circuit board, cause circuit board originally
Therefore the design difficulty of USB3.0 connector is all higher than current existing all kinds of connectors.
[summary of the invention]
