Socket electrical connector 【0001】

The present invention relates to a socket electrical connector, and more particularly to a socket electrical connector for plugging the connector electrical connector forward and backward.

【0002】

Electronic devices transmit electrical signals between the electrical connectors, such as the commonly used Universal Serial Bus (USB) electrical connectors. The existing USB Type-C socket electrical connector can be plugged in forward and reverse of the plug electrical connector, and includes an insulative housing, a double row of terminals and a shielded housing. The insulative body is typically made of plastic and includes a tongue plate. The two rows of terminals are fixed to the insulative housing, wherein the flat contact portions of one row of terminals are disposed on the surface of the tongue plate, and the flat contact portions of the other row of terminals are disposed on the lower surface of the tongue plate. The shield case is usually made of metal and is wrapped around the insulative body, that is, the tongue plate and the double row of terminals disposed thereon. When the socket electrical connector adopts a sinker type design, it can be soldered to the circuit board by using a set of soldering legs which are bent at the rear of both sides of the shielding shell, but only the soldering foot at the rear is fixed, which is easy to cause the whole socket electrical connector. Unstable, so that the shielding shell can be formed into another set of welding feet by tearing the shell wall, and the formed welding legs are located at the front sides of the shielding shell, and are welded by the welding legs of the front and rear parts of the shielding shell. The circuit board can effectively improve the stability of the socket electrical connector after being integrally fixed, and is not easy to be detached. However, by tearing the shell wall of the shield case to form the soldering leg, the shield case is inevitably opened. When the shield case is lacking as a shield, the signal terminals in the terminal are susceptible to electromagnetic wave interference during high-speed signal transmission ( Electromagnetic Interference (EMI), which causes the shielding effect of the shielding case to be deteriorated.
