A connector may look simple from the outside, but its performance depends heavily on the design of its internal components. Among them, the terminal and housing are two of the most critical elements. Their material selection, structural design, plating, mechanical properties, and manufacturing tolerances directly affect electrical performance, reliability, durability, and service life. This article introduces the basic structure of connectors and highlights several key considerations in...

In the design of high-current connectors, busbars, power terminals, and industrial connectors, engineers typically focus on electrical conductivity, contact resistance, corrosion resistance, and plating thickness. However, another critical question is often overlooked: What happens to the plating when a connector operates at elevated temperatures for extended periods? Tin, silver, gold, and nickel are all commonly used plating materials for electrical contacts, but their failure mechanisms at...

A product may be designed for a 10-year service life, yet its specification may require only 24, 48, 96, or 240 hours of salt spray testing. So, does 48 hours of salt spray testing represent 10 years of actual use? And if 48 hours represented 10 years, would 480 hours represent 100 years? The answer to both questions is no. Salt spray testing is not a service-life test. It is an accelerated corrosion test designed to reveal weaknesses in materials, surface treatments, plating, coatings, and...
