The present invention relates to an electrical connector structure, and more particularly to an electrical connector structure that is applied to the USB 3.0 specification and that can increase the soldering strength welded to the circuit board.

With the increasing demand for convenient applications of electronic products, and thus the continuous attention of various manufacturers, in order to improve the competitiveness of electronic products, manufacturers must constantly strengthen and expand the functions of electronic products, so all kinds of electronic products are oriented In addition to being thin and light, the structure and transmission speed of the model are also required to be increased, so as to improve the convenience of the user in operation and use.

Since electrical connectors are used to connect signals between electronic products or between components in an electronic product, the importance of electrical connectors in electronic products is beyond words. How can manufacturers easily assemble electrical connectors during manufacturing? , to reduce the cost of assembly, while at the same time taking into account the effectiveness of electrical connectors, has become a competition among manufacturers.

In the electronic connector, the USB connector also has the biggest breakthrough. The USB (Universal Serial Bus) universal serial bus is a serial bus standard for connecting external devices. It is widely used on computers and is the most common. Specifications can also be used in set-top boxes and game consoles. Even many industrial instruments are connected to computers via USB. USB not only provides peripheral device data transmission, but also power supply. On-The-Go plug-and-play features are more. Can make portable devices straight Exchange data.

USB has been USB1.0 since its inception, and its transfer speed is 1.5Mb/s. In 1998, the USB 2.0 specification was introduced, and the transmission speed was increased to 12Mb/s. 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 of the USB2.0 specification.
