Description

Circuit board near-far single-side bridge type electrical connector assembly

The present invention relates to the technical field of an electrical connector, and in particular to a circuit board near-end and far-end single-side bridge-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.

Since the existing electrical connector structure is directly welded to the main circuit board to form an electrical connection, a welding process is required in 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 circuit board proximal and distal single-side bridge-type electrical connector assembly, in which the other end of the first terminal is not connected to the circuit board using a welding process, but is connected to the opposing connector of the main circuit board through a docking circuit board. In this way, there is no need to use a welding process, which solves the problem of complicated processes in the existing technology and the problem of being unable to expand the scope of application due to the limitation of the circuit board structure.
