Description

Technical Field

[0002] Before leaving the factory, the charging interfaces of electronic products must undergo conductivity testing to ensure the stable and reliable charging function of the finished product. Current conventional testing methods rely on manual, piece-by-piece operation: operators use power strips and data cables to connect the charging interface modules to the testing equipment, and by switching between different test voltages and currents, test performance indicators such as charging rate and power loss. This manual testing mode has many drawbacks: overall testing efficiency is low, and the labor intensity is high; manual insertion and removal are prone to errors such as improper insertion and poor contact, leading to distorted test data, significantly reduced testing accuracy, and a high risk of missed defects and misjudgments.
