Description

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 allows the USB Type-C plug electrical connector to be inserted in the forward and reverse directions, 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. The shielding case forms a plugging space with the tongue plate for plugging the USB plug electrical connector. However, when the USB Type-C socket electrical connector is plugged into the USB Type-C plug electrical connector, only the fixing structure of the socket electrical connector at the front end of the tongue plate and the clamping connector of the plug electrical connector on the inner side are only used. (latch) The insertion and extraction force that reaches each other is clamped. However, the insertion and extraction force is not effective, and after a long period of continuous use, the insertion force is easily lowered, and the plugging resistance is deteriorated.

[0003]

The purpose of this creation is to provide a socket electrical connector for plugging the connector electrical connector in the forward and reverse directions, which provides a better insertion and extraction force and improves the plugging resistance.

[0004]

In order to achieve the above object, the present invention proposes a socket electrical connector, wherein the socket electrical connector is plugged into the plug electrical connector, wherein the plug electrical connector comprises a shielding outer casing, and the shielding outer casing forms two opposite docking spaces. The socket electrical connector includes an insulative housing, a plurality of first terminals, a plurality of second terminals, and a shielding housing. The insulative housing has a base body and a tongue extending forward from the base body. Each of the first terminals has a first fixing portion, a first contact portion and a first soldering portion. The first fixing portion is fixed to the base body, and the first contact portion extends forward from the first fixing portion and is disposed on the lower surface of the tongue plate. The welded portion extends outward from the first fixing portion to the base body. Each of the second terminals has a second fixing portion, a second contact portion and a second welding portion. The second fixing portion is fixed to the base body, and the second contact portion extends forward from the second fixing portion and is disposed on the surface of the tongue plate. The welded portion extends outward from the second fixing portion to the base body. Further, the first terminal and the second terminal are disposed in point symmetry. The shielding shell has a top wall, two side walls and a bottom wall, and the top wall, the two side walls and the bottom wall together form an accommodating space for accommodating and covering the insulating body, and one of the top wall and the bottom wall is provided with the first elastic piece The two side walls are provided with a plurality of welding legs outward. The shield housing and the tongue of the insulative housing together form a docking space for plugging the plug electrical connector. When the plug electrical connector is inserted into the socket electrical connector in the forward or reverse direction, the first elastic piece of the socket electrical connector is located at the corresponding docking space of the plug electrical connector.

[0005]

In an embodiment, a second elastic piece or a convex hull is disposed on each of the top wall and the bottom wall of the shielding case.

[0006]

The socket electrical connector of the present invention is provided with a first elastic piece on the top wall or the bottom wall of the shielding case, and the shielding outer casing of the plug electrical connector is provided with two opposite docking spaces, when the plug electrical connector is forward or reverse When the connector is plugged into the electrical connector of the socket, the first elastic piece of the electrical connector of the socket is located at the corresponding docking space of the electrical connector of the plug. Therefore, the first elastic piece and the plug of the housing are shielded by the electrical connector of the socket. The connector shielding shell provides further insertion and extraction force corresponding to the docking space, and the insertion and extraction force is not easily reduced after multiple insertions and removals, thereby providing a better insertion and extraction force and improving the plugging resistance. In addition, the bottom wall or the top wall of the shielding shell not provided with the first elastic piece may be provided with a second elastic piece or a convex hull on both sides, thereby reducing the space of the plug electrical connector in the electrical connector of the socket, and ensuring the insertion time. The stability of the contact, in turn, provides a better grounding effect.
