In today’s globalized market, power sockets are used in a wide variety of applications ranging from household appliances to industrial equipment. In order to ensure product safety, compliance, and market access, manufacturers must obtain relevant certifications in different countries and regions. However, certification requirements, testing standards, and regulatory focus vary widely between systems such as UL (USA), VDE and TUV (Germany), CCC (China), PSE (Japan), and KC (South Korea). Understa...

In modern power socket design, ensuring long-term electrical performance and safety is essential. One often-overlooked but technically vital factor is contact resistance—the resistance encountered where conductive surfaces meet, such as between socket terminals and inserted plugs. High contact resistance can lead to localized heating, power loss, arc discharge, and even fire hazards. This article explores how to achieve low contact resistance through proper material selection, structural design,...

As automotive electronics and intelligence advance, vehicle electrical systems are evolving from traditional 12 V low-voltage networks toward 48 V mild-hybrid and higher-voltage architectures. As core circuit-protection and isolation components, fuse holders must not only handle high currents and short-circuit capacities but also withstand severe mechanical shocks, electromagnetic interference, and harsh environmental conditions. This article analyzes fuse-holder applications in automotive elect...

In applications such as new energy systems, rail transit, and automotive engine compartments, fuse holders often face temperature cycles from –40 °C to +150 °C or even higher. High-temperature environments not only accelerate material aging but also cause differential thermal expansion that can loosen mating parts and raise contact resistance, thus undermining circuit protection and overall system reliability. Based on years of experience in developing electronic switches and protection componen...
