[Prior Art] [0002] The Universal Serial Bus (USB) interface as a standard input/output interface has been widely used in the design of many electronic devices, such as PCs and mobile phones. Electronic products such as digital cameras and music players. Due to the limitations of product shape or cost, most of the mobile devices use a micro USB structure. With the development of technology, such products have higher requirements for the stable cooperation of the USB structure in use. The Chinese Patent Publication No. CN201 041871Y discloses such an electrical connector comprising two upper and lower shielding housings, an insulating body, a locking device mounted in the insulating body, and a terminal disposed on the insulating body. The locking device is composed of two mutually independent sheet-like structures, which are inserted and mounted on the two sides of the insulating body by the back of the insulating body. [0003] However, it is unavoidable to repeatedly insert and remove the USB connection device during use, and the locking device is installed in the channel disposed in the insulating body. With the development of miniaturization of the electrical connector, the structure of the locking device The strength is also weakened. Therefore, after repeated insertion and removal, the locking device will become loose due to the force, and thus it is impossible to provide a durable and stable stable connection, affecting the normal use of the electrical connector, and not meeting the requirements of modern products. In view of the above, it is necessary to provide an improved electrical connector to overcome the drawbacks of the electrical connector described in Form No. A0101, page 4 of the total number of M408833.
