Description

TECHNICAL FIELD

In practical application, the row female connector needs to be inserted into the PCB board, and a series of avoiding holes corresponding to the row pin of the row female connector are provided on the PCB board to facilitate subsequent signal wire welding operation.

[0003] In the patent with the publication number CN214013219U, a row female connector with high plug-in reliability is disclosed, which is plugged with the PCB board and includes an insulating plastic body and a row pin unit.
