Description

Double tongue plate and two-way mating type female electrical connector

The present invention relates to the technical field of an electrical connector, and in particular to a double-tongue plate capable of bidirectional docking and a bidirectional docking female electrical connector.

Electrical connectors are used to connect different electronic components or modules so that electronic signals can be transmitted between different electronic components or modules through the electrical connectors. The electrical connector is connected to the counterpart connector, and then the signal is transmitted by the terminals of the electrical connector itself contacting the terminals of the counterpart connector. The front end of the existing electrical connector forms a docking interface with the counterpart electrical connector, and the rear end is combined with the circuit board. One end of the terminal is connected to the terminal of the counterpart electrical connector, and the other end of the terminal is welded to the circuit board, so that the electronic signal is transmitted from the electronic device to the circuit board through the docking of a pair of electrical connectors.

Since this existing electrical connector structure must be used with a circuit board to form an electrical connection, a welding process must be implemented during the manufacturing process to connect the electrical connector to the circuit board. This not only makes the manufacturing process more complicated, but is also limited by the structure of the circuit board, and its application range is also limited.

In view of this, the purpose of the present invention is to provide a double-tongue plate and a two-way docking type female electrical connector, the other end of the terminal is not connected to the circuit board using a welding process, but forms another docking end to dock with another counterpart connector. In this way, there is no need to use a welding process and no circuit board is used, which solves the problem of complicated processes in the existing technology and the problem of being limited by the circuit board structure and being unable to expand the scope of application.
