How does the touch finger spring function in the slip ring component

The application of touch finger springs in slip ring components can achieve stable transmission of current or signals under dynamic rotation. The touch finger spring is arranged in a continuous ring shape, covering the contact surface along the axial or radial direction of the slip ring, and maintaining a constant contact force through elastic deformation, effectively compensating for small displacement and deflection errors during rotation. Multiple contacts are formed between the spring and the conductive ring, dispersing the contact current, reducing single point load, and improving conductivity stability. Compared to traditional graphite brushes, the contact finger spring has smaller friction and lower contact resistance, reducing heat generation and extending the service life of the slip ring. The use of gold-plated or silver plated contact finger springs can further improve conductivity and adapt to stable transmission of weak or high-frequency signals. The compact touch finger spring can adapt to high-speed slip ring systems and reduce electrical signal loss caused by contact vibration.

High resilience materials ensure that the contact pressure does not significantly decrease during multiple rotation cycles, providing a reliable solution for applications such as aerospace, radar antennas, and detection equipment that require high continuous rotational conductivity. By designing the layout of the finger spring reasonably, electromagnetic interference can be effectively reduced, and the overall electrical performance and mechanical durability of the slip ring component can be improved.
