Socket electrical connector

The present invention relates to an electrical connector, and more particularly to a socket electrical connector capable of protecting the tongue portion of the insulative housing, improving the rigidity of the tongue portion of the insulative housing, and preventing damage to the receptacle electrical connector.

Universal Serial Bus (USB) connector, generally known as USB connector, has been widely used for signal transmission in various occasions due to its plug-and-play and fast transmission speed. With the development of USB connectors, people have more needs for transmission speed and stability.

At present, USB2.0 is widely used as a transmission interface on the market. With the increasing popularity of digital multimedia and the continuous expansion of transmission files, USB2.0 has been unable to meet the needs of the market. USB3.0 is backward compatible, and combines the ease of use and plug-and-play functionality of traditional USB technology. The goal of this technology is to launch products that are 10 times faster than current connectivity standards. The same architecture, in addition to USB optimization to achieve lower power consumption and higher protocol efficiency, and support future optical fiber transmission, compared to USB2.0 transmission speed of 480Mbps, USB3.0 transmission speed Up to 5Gbps.

The existing USB connector socket structure mainly comprises: an insulating body, a plurality of terminals, and a metal casing. The insulative housing includes a base portion and a tongue portion extending forwardly from the base portion, and the tongue portion is provided with a receiving groove penetrating the base portion. The terminal is inserted into the receiving groove of the insulative housing. The metal casing is coated on the outside of the insulation body. In the micro-USB structure, the USB connector further includes a protection board to reduce radio frequency interference (RFI) or electromagnetic interference (EMI), and to improve the rigidity of the tongue portion of the insulative body. Generally, the protective plate is bent to form a front portion and two side portions to cover the outside of the tongue portion.

Since the micro-USB socket electrical connector usually requires a lot of plugging and unplugging. Therefore, the protective plate is made of a metal material to cover the tongue portion to achieve a protective effect.
