Description of the invention: [Technical field of the invention] The present invention relates to a USB connector that can be double-sidedly inserted, in particular, a USB double that can be connected with a USB standard on both sides, and has no direction limitation. Face connector. [Prior Art] The types of external peripheral devices of personal computers have become more and more abundant in recent years. Keyboards, mice, printers, and scanners have long been known. CCD cameras, digital cameras, MP3 players, external hard drives, etc. And, if the parallel and serial connection is not enough to meet the needs of users, the introduction of USB can undoubtedly solve this problem. The advantages of USB are as follows: First, it can support hot-swap technology and plug-and-play function. This allows users to easily add peripheral devices to the computer, and the USB interface does not use _ interrupt control and input and output address resources. , can connect up to 127 devices. In addition, the other advantage of the coffee interface is that the transmission speed is fast. With the new generation of usb 2 〇 specification, the transmission bandwidth of the poor material is significantly expanded. USB 2.0 (universal serial bus) is jointly developed by many manufacturers. Includes Compaq, Hewlett-Packard, Intel, Lucent, Microsoft, NEC and Philips. A high-speed data transfer mode has been added to the white USB 1.1 specification. In (4) 2.0, in addition to the two modules specified in USB1.1 and 1 2Mbit/s ^ ^ _ 揭 u, the increase of 480Mbit / s (60MB / S), the door speed mode, due to the increase High-speed mode will make the application range of USB more in one. ^V is expanded. In addition, USB2.0 also has downward compatibility 1248704.
的特性，可以使用原來USB1.1定義中同樣規袼的電欖， 接頭的規格也完全相同，在高速的前提下一樣保持了 USB 1·1的優異特色，且不會和USB 1·Χ設備在共同使用的時 候發生任何衝突。 就目剷市面上各式週邊設備的U S Β公接頭來看，係僅 能以單一面插設於USB母連接埠内，若是將該USB公接 頭翻轉後，受限於USB連接埠内一擋塊加以抵止，該公接 頭便無法連接於母連接埠内，該擋塊之設置目的是為了確 保公接頭上的四個導電端點能正確地與連接埠内的四個端 點構成對應接觸，以避免電源端與接地端誤接。 針對某些USB裝置來說，若是僅能以單一方向插接於 連接埠内，於實際操作應用時將極不方便。舉例而言，如 第/、圖所不，對於直接在卡體上形成有USB接頭的記憶卡 σ若採單方向插设在電腦面板上的連接蟑，卡體側 j可此又面板部份的擋止而無法令USB接頭順利插入，此 時若可將記憶卡翻轉後，令咖接頭改採另—面插入連接 埠，便能解決此一問題The characteristics of the original USB1.1 definition can be used in the same specification, the specifications of the connector are also the same, under the premise of high speed, it maintains the excellent features of USB 1.1, and does not work with USB 1·Χ Any conflicts occur when used together. As far as the US Β male connector of various peripheral devices on the market is concerned, it can only be inserted into the USB female connector in a single face. If the USB male connector is turned over, it is limited to the first one in the USB connection. When the block is resisted, the male connector cannot be connected to the female connector. The purpose of the stopper is to ensure that the four conductive terminals on the male connector can properly contact the four end points in the connector. To avoid misconnection of the power supply terminal and the ground terminal. For some USB devices, if they can only be plugged into the connector in a single direction, it will be extremely inconvenient for practical applications. For example, if the memory card σ with the USB connector formed directly on the card body is inserted into the connector on the computer panel in a single direction, the card body side j can be the panel portion. The blocking of the USB connector can not be smoothly inserted. At this time, if the memory card can be turned over, the coffee connector can be replaced with another interface, and the problem can be solved.
