Description

Two-way docking single-side electrical connection type electrical connector assembly

The present invention relates to the technical field of an electrical connector, and in particular to a two-way docking single-side electrical connection type electrical connector assembly capable of bidirectional docking.

An electrical connector is used to connect different electronic components or modules so that electronic signals can be transmitted between different electronic components or modules through the electrical connector. The electrical connector is connected to the counterpart connector, and then the signal is transmitted by the first terminal of the electrical connector itself contacting the first terminal 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 first terminal is connected to the first terminal of the counterpart electrical connector, and the other end of the first terminal is welded to the circuit board, so that the electronic signal is transmitted from the electronic device to the circuit board through the connection of a pair of electrical connectors.
