[Prior Art] In November 2008, the next-generation USB 3·〇 (SuperSpeed USB) standard, which was developed by industry giants such as Inte, Microsoft, Hewlett-Packard, Texas Instruments, Nec, and ST-NXP, was officially completed and released. The USB 3.0 standard delivers ten times the transfer rate of USB 2.0 and higher energy efficiency, making it suitable for a wide range of peripheral devices and consumer electronics. The development process of USB (Universal Serial Bus) standard is as follows: The first version of USB 1.0 appeared in 1996, the speed is only i.5Mb/s; after two years, it is upgraded to USB 1.1, and the speed is greatly improved. i2Mb/s; April 2000's USB 2.0, which is widely used, has reached a speed of 48〇Mb/s. However, the speed of USB 2.0 has long been unable to meet the needs of the application; 2〇〇8 years u month, USB 3.0 also came into being, with a maximum transmission bandwidth of up to 5 〇 Gb/s. The USB 3 · 〇 standard defines the A type socket (Receptade) and the plug (Plug), and the USB 3 '0 type A plug can be connected to the previous generation USB 2 〇 socket. Compared to the previous generation of USB 2.〇 Class A plugs, the USB 3 〇 Class A plug adds 5 flex terminals (pins) for a total of 9 terminals. The added $ terminals are a pair of high-speed differential signal terminals, a ground terminal, and a pair of high-speed differential signals 4 M429243 terminals. The rear end of the above-mentioned nine terminals extends out of the rear end of the plug insulating body for soldering with the corresponding cable. Since the tails of the nine terminals are densely arranged, it is usually necessary to manually align the terminal tail and the cable for welding during the welding process. It is prone to twisting lines, affecting production efficiency, and is not conducive to rapid welding assembly during mass production, and is not conducive to cost reduction. In view of the above problems, it is necessary to design a cable connector which is easy to quickly assemble and assemble to solve the above technical problems. [New Content] The purpose of this creation is to provide a cable connector that facilitates quick and easy solder assembly.
