Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector conforming to the USB 3.0 specification, and the contact portion of the conductive terminal and the center of the soldering portion are not on the same line.

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 the electrical connector structure is used to connect signals between electronic products or between components in an electronic product, the importance of the electrical connector structure in electronic products is beyond words. How do manufacturers construct electrical connector structures? It is easy to assemble, reduce the assembly cost, and at the same time can take into account the function of the electrical connector structure, 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 the computer via USB. USB can not only provide peripherals. Device data transmission, but also power supply, On-The-Go plug-and-play features allow portable devices to directly exchange data.

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.
