Therefore, how do manufacturers make electrical connectors easy to assemble during manufacturing and reduce The cost of assembly and the function of the electrical connector at the same time have become a point of competition among various manufacturers.

In electrical connectors, there is also the biggest breakthrough in USB connectors. USB (Universal Serial Bus) is a serial bus standard for connecting external devices. It is widely used on computers and is the most common specification. It can also be used on set-top boxes and game consoles, and even many industrial instruments are connected to computers through USB. USB can not only provide peripheral equipment data transmission, but also provide power supply. Portable devices exchange data directly.

USB has been the USB1.0 specification from the beginning, and its transmission speed is 1.5Mb/s, and the USB2.0 specification was introduced in 1998, and the transmission speed was increased to 12Mb/s, and this specification has been widely used in electronic products , and the latest USB3.0 specification has increased the transmission speed to 5.0Gb/s, which is more than 10 times that of the USB2.0 specification. Because the speed is much higher than before, it has become a product to be promoted by various manufacturers in the future.

Therefore, with the prospect of USB3.0 specification products in the future, how to achieve the purpose of simple manufacturing of USB3.0 products has become an urgent problem for manufacturers to overcome.
