Plug electrical connector and electronic device having plug electrical connector

The present invention relates to a plug electrical connector and an electronic device having a plug electrical connector, and more particularly to a plug electrical connector that is provided with a surface-adhesive terminal, such as an electrical connector that can be applied to a USB Type-C male end. And an electronic device having the plug electrical connector.

Electrical connectors have been widely deployed within electronic devices for transmitting power or signals. Due to the high speed of signal transmission and various other functions, the number of terminals of the electrical connector is increasing, but the volume requirement of the electrical connector is getting smaller and smaller. How to properly solder the electrical connector to the board has become a problem in assembly.

For example, in the USB (Universal Serial Bus) specification, the design of the 22-pin or 24-pin of the USB Type-C specification from the first 4-pin of the Type A specification is about 8.4mm x 2.6. Mm, the pins are getting denser and denser. Among them, the plug connector of USB Type-C has 22 terminals divided into upper and lower terminals (the lower row excludes USB 2.0 differential signals Dn2, Dp2), so it is necessary to set a riser card at the end of the plug connector (Paddle Card) or board connection. In order to properly solder a plurality of terminals to the riser card, one way is to arrange the plurality of terminals into two rows, one row being a surface mount type (SMT) terminal and the other row being a jack type (DIP) solder terminal. This approach requires drilling holes in the riser card or board, which is time consuming and not suitable for all riser cards or boards. Another way is to arrange two rows of surface mount type (SMT) terminals, which are soldered to the same surface of the riser card in the front and back rows. The inspection procedure after welding is relatively difficult because the front row is usually covered by the electrical connector itself. Alternatively, the two rows of surface mount type (SMT) terminals are respectively soldered to the upper and lower surfaces of the riser card, which is difficult to manufacture in the terminal plane.
