Rack Busbar Groove Interface for Low-Resistance ESS Terminals

The contact structure is segmented into a protruding portion on the rack busbar and a corresponding groove on the terminal portion. This segmentation creates multiple discrete contact points rather than a single flat contact surface, preventing dust accumulation while maintaining manufacturing simplicity.

Instead of having a flat busbar contact a flat terminal surface, the design inverts the conventional approach by creating a protruding portion that fits into a groove. This inversion eliminates the dust-trapping flat contact space while maintaining ease of assembly and manufacturing.

The contact interface is divided into a protruding portion and a groove structure, creating a segmented design that prevents dust accumulation. This segmentation maintains simple manufacturing while effectively eliminating the harmful flat contact space where dust would accumulate.

The groove structure, which initially appears to create additional complexity, actually converts the potential harm of dust accumulation into a benefit by providing a dust-exclusion mechanism. The groove design naturally prevents dust entry while maintaining ease of manufacture.

The conventional flat contact structure is inverted into a protruding-groove configuration. This inversion creates a dust-exclusion mechanism that prevents vibration-generated dust from entering the contact space, thereby maintaining electrical connection stability during mobile UPS operation.

The groove structure converts the harmful effect of vibration-induced dust into a beneficial dust-trapping mechanism. The groove design ensures that even when vibration occurs, dust cannot enter the contact interface, maintaining stable electrical connections throughout operation.
