Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector that is configured to pass through a fixed terminal to increase the soldering strength of the soldered 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.

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. Enables portable devices to exchange data directly.

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

Therefore, in the future of USB3.0 products, how to achieve the purpose of simple manufacturing of USB3.0 products has become a problem that manufacturers need to overcome, and the required connection of USB3.0 products. There are a large number of terminals, so how to increase the welding strength of the USB3.0 electrical connector soldered to the circuit board of the electronic product is also one of the problems that need to be overcome at present.
