Spring Contact Fingers

Product Features and Application Fields

Product Features

• Strong current-carrying capacity;
• Simple structure, convenient assembly, economical and practical;
• Small size, multiple contact points, and minimal heat accumulation;
• No electric sparks generated by impact, with automatic arc-extinguishing function;
• Each coil works independently, which can correct large-area contact tolerances and compensate for surface irregularities, thereby effectively solving the problem of resistance drift;
• Can maintain good performance under impact, vibration, and harsh environments.

Application Scope

• High and Medium Voltage Electrical Equipment: Realize high-reliability and low-loss conductive connections, adapt to vibration, temperature deformation, and installation deviations during equipment operation, and are mainly used in key components such as switchgear, transformers, and instrument transformers.
• New Energy Equipment: In high-voltage connectors, they can achieve high-reliability electrical connections to ensure the stable operation of high-voltage circuit systems. When used in charging modules, they can ensure tight contact between charging piles and vehicle charging interfaces, enabling efficient and fast charging.
• Power Transmission Switchgear: Ensure reliable conductive connections in high-voltage and high-current scenarios, adapt to vibration, temperature deformation, and installation deviations during equipment operation, and are mainly used in key equipment such as GIS, circuit breakers, and disconnectors.
• Mining Equipment: In junction boxes of coal mine electromechanical equipment, they can be used to fix wires. The elasticity of spring contact fingers can ensure reliable clamping of wires; compared with ordinary connection methods, they can provide more connection points, and at the same time, can adapt to a certain vibration environment in mines, prevent wire loosening, and ensure the stability and safety of power supply.
• Oil Exploration Equipment: Their core function is to provide high-reliability and vibration-resistant electrical connections and signal transmission for key components, ensuring the stable operation of equipment in extreme downhole environments (high temperature, high pressure, and strong vibration).
