Feature: 1. Using thickened copper inner core, the load is large, the resistivity is small, the electrical conductivity is good, and the wiring is stable and reliable. 2. The outer layer is tin plated and is resistant to oxidation, which can prevent the copper core from being exposed to the air for a long time to form patina and maintain strong electrical conductivity. 3. The shell adopts high insulation protection, and the terminal shell adopts thickened insulating flame retardant casing for effective protection. 4. The inner core ring has a notch design, which is suitable for the male connector to be inserted into the tension to expand outwards, and the hollow slot inside is stuck firmly when inserted. 5. A wide range of applications, suitable for automotive terminals, audio isolation switches, machines, home decoration, and many other applications.
