Description

Connector assembly and plug connector

The invention relates to a connector assembly and a plug connector thereof which can increase the signal transmission rate.

At the end of 2008, the USB Association released the 3.0 version of the USB standard. This USB 3.0 connector is based on the original USB 2.0 connector. Two pairs of differential signal terminals and one grounding terminal are added to enhance the original. The transfer rate of the USB connector. The USB 3.0 connector has a transfer rate of 5G per second and can be plugged into both USB 2.0 and USB 3.0 docking connectors. However, due to the large number of conductive terminals on the USB 3.0 connector, the internal structure of the cable connected to the back side of the USB 3.0 is complicated, the cable is heavy and the high frequency is so long that it can only be set up to 5 meters, which is inconvenient to consume. Use of the person. In addition, the transmission speed of the USB 3.0 connector still cannot meet the transmission requirements of large-capacity electronic devices such as Blu-ray DVD.

In order to overcome the above problems, optical fibers have been widely used in the field of electronic communication, and optical fibers can be used instead of metal cables to achieve low loss, long distance, and low interference transmission effects. Therefore, the connector manufacturers add a fiber optic module based on the USB socket connector and the USB plug connector to form a fiber optic USB socket connector and a fiber optic USB plug that can transmit both optical signals and electrical signals. The connector, the fiber-optic USB socket connector or the fiber-optic USB plug connector can be electrically connected not only to the conventional USB plug connector or the USB socket connector, but also to the transmission requirements of common electronic devices. The group performs high-speed optical signal transmission to meet the signal transmission requirements of electronic devices for high-definition transmission. The optical fiber USB socket connector generally includes an insulating body to set the optical fiber module for transmitting optical signals; a USB terminal is disposed on the insulating body to transmit an electrical signal; and a metal outer casing covers the insulating body.
