Mechanical structure is the basic line of defense against misinsertion, which is mainly achieved through differentiated design of physical dimensions and shape.

Testing the grounding protection function of a power strip requires a combination of physical inspection, electrical testing, and simulation verification, and relies on specialized tools to ensure accurate results.

In homes, offices, and public spaces, power sockets may seem ordinary, but they are the crucial "last mile" hub for accessing electricity.

With its built-in current detection circuit, the socket can monitor the current value passing through the circuit in real time and compare it with a preset safety threshold.

Modern sockets use power filters as key components to filter out high-frequency harmonics through low-pass filtering circuits.

While retaining the advantage of multi-standard compatibility, the universal socket significantly improves home electrical safety through a number of innovative designs, becoming a crucial component of modern household power management.
