Description

Electrical connector female 【0001】
This creation relates to electrical connectors, and more particularly to electrical connector females.
【0002】
Nowadays, the electronics industry is developed, and various electronic devices are filled with the general public's life. In order to transmit control commands, multimedia materials and even power, most electronic devices are equipped with one or more connectors.
[0003]
The most common connectors on the market today are the Universal Serial Bus (USB) connectors. In general, USB A-Type is the most widely used and most popular USB interface; USB Micro-B is a relatively small USB interface, mainly used in portable devices such as smart mobile devices and tablets. In order to effectively apply to thinner and thinner devices, the USB development organization has recently proposed the USB C-Type interface.
[0004]
According to the currently disclosed information, the connection terminals provided on the USB C-Type connector are about twenty-four, but the area (generally the area of the tongue) is only about half of that of the USB Micro-B. At such a small tongue area, at least twenty-four connection terminals are required, which makes the USB C-Type connector difficult to produce and assemble.
[0005]
Moreover, since twenty-four connection terminals are to be provided on a small tongue area, each connection terminal needs to be narrow and thin, which causes the manufacturing yield of the terminals to be prone to problems. And the manufactured terminals are easily damaged during assembly.
[0006]
The main purpose of the present invention is to provide an electrical connector female connector which is formed by a printed circuit board to form an electrical connector having three layers of guiding terminals, thereby eliminating the use of terminals to throttle the production of the connector. With the assembly process.
【0007】
In order to achieve the above object, the female connector of the present invention mainly comprises a printed circuit board and a first conductive terminal group, a second conductive terminal group and a grounding terminal electrically connected to the printed circuit board. The printed circuit board has at least a bottom layer on a lower surface, a top layer on an upper surface, and a ground layer between the bottom layer and the top layer. One end of the bottom layer is provided with a first gold finger set, and one end of the top layer is provided with a second gold finger set, and one end of the ground layer is provided with at least one ground contact. The first conductive terminal group is electrically connected to the first gold finger set on the printed circuit board, and the second conductive terminal group is electrically connected to the second gold finger set on the printed circuit board, and the ground terminal is electrically connected The ground contact on the printed circuit board is connected.
[0008]
The technical effect achieved by the present invention in comparison with the prior art is that the original lower layer terminal is replaced by a gold finger set provided on the bottom layer of the printed circuit board, and the original upper layer terminal is replaced by a gold finger set provided on the top layer, thereby eliminating the need for the above. Use of terminals. Moreover, since the gold finger set can be directly fabricated in the manufacturing process of the printed circuit board, replacing the above terminals with a gold finger set can also effectively simplify the production and assembly process of the electrical connector.
【0009】
Furthermore, if a multi-layer printed circuit board is used, one of the layers can be directly used as a ground layer, and the electrical connector can be grounded through the ground layer. In this way, it is not necessary to additionally provide a metal piece or a metal terminal for grounding on the tongue of the original electrical connector, so that the production and assembly speed of the electrical connector can be improved, and the production cost of the electrical connector can be effectively reduced.
