Why Are Copper Terminal Blocks So Resistant To Vibration?

Vibration resistance is one of the important indicators for evaluating the stability of copper terminal block, which reflects the ability of copper distribution block to maintain contact continuity under vibration load. Vibration generates periodic stress cycles on the metal contact surfaces within copper terminal strip. If these mechanical loads exceed the structure's bearing capacity, they can lead to connection instability or even electrical contact breakage.

Vibration assessment typically employs standardized test benches to simulate actual operating conditions. By combining frequency and amplitude, the vibration environment during equipment operation is reproduced, and the continuity of the terminal blocks and changes in contact resistance are continuously monitored. If the resistance fluctuation remains within acceptable limits, it indicates that the component maintains a good electrical path under stress, thus exhibiting excellent vibration resistance.
