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 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 shielding shell is usually made of metal and is formed by drawing or bending, and is covered on the insulating body, that is, the tongue plate and the double row terminals disposed thereon. The shielding shell forms a docking space with the tongue plate for plugging the USB plug electrical connector.

[0003]

The shielding shell is formed by drawing. Firstly, according to the shape of the shielding shell designed, the sheet material sufficient to form the required area of the shielding shell is cut out on the flat metal sheet, and the drawing of the sheet material during molding is considered. Appropriate edge material required for stretching and deformation; then, the sheet obtained by the above cutting is continuously drawn and drawn several times by the drawing technique until a completely formed and bottom-closed shielding shell is obtained, and at each extraction In the process, the corresponding punch is gradually approached according to the order of the shielded casing. In the end, the bottom edge of the shielded shell is cut and punched by using a punch with a cutting edge. The shield case having a hollow shape is obtained; therefore, the process required for the drawing forming is high and the manufacturing process is cumbersome, and the manufacturing cost is relatively increased. The shielding shell is formed by bending and wrapping, and the flat metal sheet is continuously stamped and bent several times until the edges of the free state on both sides are fastened together to form a shielding shell with a polygonal frame shape; therefore, The manufacturing process required for bending overmolding is cumbersome and relatively increases the manufacturing cost.

[0004]

The purpose of this creation is to propose a socket electrical connector for plugging the connector of the plug in the forward and reverse direction. The shielding shell is designed in two-piece structure, which can be directly stamped and assembled before being assembled. The process is low and the manufacturing process is simple, which relatively reduces manufacturing costs.

[0005]

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 plurality of first terminals and the plurality of second terminals are arranged in point symmetry. The shielding housing includes a first shielding shell member and a second shielding shell member. The first shielding shell member and the second shielding shell member are connected to form an accommodation space for accommodating and covering the insulating body, the first shielding shell member and/or Or the second shielding shell member is 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.

[0006]
