Description

TECHNICAL FIELD

[0001] The present application relates to a socket connector and an assembly thereof. BACKGROUND

[0002] USB 3.1 is the latest USB specification, which is initiated by large companies such as Intel. The data transmission speed can be increased to 10 Gbps. Compared with the traditional USB 2.0 technology, the new USB technology uses a more efficient data coding system and provides more than one times the effective data throughput. USB 3.1 includes three types: Type-A, Type-B and Type-C. In December 2013, the USB 3.0 promotion team has announced the rendering of the next generation USB Type C connector, and then in August 2014, it has been ready for mass production. The highlight of the new connector is the more slim design, faster transmission speed (up to 10 Gbps) and more powerful power transmission (up to 100 W). The biggest advantage is to support front and back insertion, which solves the problem of "USB can never be inserted".

[0003] However, in the existing such connector, due to the large number of terminals for transmitting signals, and in order to meet the structure design requirements such as miniaturization, when the finished socket connector is assembled and welded to the mating circuit board, there is often a possibility of virtual welding or empty welding of the terminals to the mating circuit board, resulting in poor signal transmission of the terminals to the mating circuit board.

[0004] Therefore, it is necessary to design a new socket connector and an assembly thereof to solve the above technical problems. CONTENT OF THE INVENTION
