USB接頭是一種用於串列通信的接頭，其具有傳送速率高、供電簡單、安裝配置便捷和相容良好的優點，應用廣泛。現有技術下的USB接頭的插拔需要依靠金屬間隔板的側面與所對接的USB介面的側壁之間的摩擦實現相對固定，使用時間長時，金屬間隔板容易出現磨損，導致USB接頭插接不牢，影響資料傳輸。並且，金屬間隔板夾裝在上連接元件和下連接元件之間，現有技術下USB接頭沒有對金屬間隔板進行定位，金屬間隔板的共面度和固定效果差，容易導致金屬間隔板變形或鬆動進而影響資料傳輸效果。 The USB connector is a connector used for serial communication, which has the advantages of high transmission rate, simple power supply, convenient installation and configuration, and good compatibility, and is widely used. The plugging and unplugging of the USB connector in the prior art needs to rely on the friction between the side of the metal spacer and the side wall of the docked USB interface to achieve relative fixation. When used for a long time, the metal spacer is prone to wear and tear, causing the USB connector to not be plugged firmly and affecting data transmission. In addition, the metal spacer is sandwiched between the upper connection element and the lower connection element. In the prior art, the USB connector does not position the metal spacer. The coplanarity and fixing effect of the metal spacer are poor, which easily leads to deformation or loosening of the metal spacer, thereby affecting the data transmission effect.
