1. Enhance contact: The spring contact finger is designed to press the busbar tightly, which helps provide better contact. Through the force of the spring, the spring contact fingers can fill the irregular parts of the contact surface, thereby preventing arcing and oxidation, further reducing contact resistance, and lowering the possibility of heat generation.

2. Stable connector: Bus connectors need to maintain stability in an electrical connection, and spring contacts provide this stability. Spring contact fingers can prevent connector separation or arcing caused by vibration, temperature changes, or other environmental factors.

3. Improve electrical performance: Spring contact fingers can also ensure electrical insulation between two busbars, while also promoting improved conductivity.

4. Simplify the installation process: The design of the spring contact finger makes the installation process easier and reduces the possibility of installation errors.

Overall, spring contact fingers play a crucial role in busbar connectors, not only improving contact stability but also simplifying the installation process, enhancing the performance and safety of the entire system.
