Description

Technical Field

[0001] The utility model belongs to the technical field of USB connectors, and in particular relates to a USB 3.0 connector. Background Art

[0002] USB stands for "Universal Serial Bus", and its Chinese name is Universal Serial Bus. It is a way to connect electronic products to each other. It is used in mobile, audio-visual, automotive electronics, multimedia, electrical appliances, etc. It has been widely used in various external devices. There are three types of USB interfaces: USB1.1, USB2.0, and USB3.0. In theory, the transmission speed of USB1.1 can reach 12Mbps / second, while USB2.0 can reach a speed of 480Mbps / second, and it is backward compatible with USB1.1. The transmission rate of USB3.0 is about 3.2Gbps (i.e. 320MB / S); the theoretical maximum rate is 5.0Gbps (i.e. 500MB / S).

[0003] like Figure 3 and Figure 4 This is a common USB connector. Relevant field personnel have found the following problems during production and use: 1. There is a material strip bridge in the middle of adjacent terminals. The material strip bridge is removed after injection molding, which increases the process and makes it difficult to cut cleanly. The presence of flying wires may cause short circuit problems, increasing costs and difficulty in management and control; 2. The structure of the shell with a back cover makes it costly and difficult to assemble, thereby reducing production speed; 3. After installation on the PCB board, the USB connector chip terminal pins cannot be identified from the top, increasing the difficulty of the terminal PCB inspection process. Utility Model Content
