Copper Cap And Fuse Terminal
The copper cap and fuse terminal are the core integrated components of a fuse assembly, undertaking the triple functions of mechanical connection with the external circuit, conductivity, and environmental sealing. This component integrates the traditionally separate fuse cap and terminal into a single unit through a precision welding process, making it a critical element determining the fuse's protection efficiency and circuit stability.

Product Introduction
The Copper Cap and Fuse Terminal is a core integrated conductive connection assembly for low-voltage fuses, power protection devices, and new energy storage fuses. It is formed from a high-purity copper cap and precision contacts using a metallurgical-grade welding process, replacing traditional separate riveting and press-fit connection structures. Specifically designed for power electronics, industrial automation, and high and low voltage protection circuits in new energy applications, it addresses common engineering pain points of separate structures, such as contact thermal resistance drift, mechanical loosening, arc oxidation, and poor batch electrical consistency.
