Electrical Connection Box Terminal Fastening

The patent combines multiple nuts and screw members into a single integrated block structure. The block contains multiple through-holes that accommodate screw members, and the nuts are positioned within the block rather than being separate components. This merging reduces the overall number of parts and compactsthe connection assembly, eliminating the need for increased busbar and block dimensions while maintaining secure terminal connections.

The patent implements nesting by placing nuts inside the block structure. The block serves as a container that houses the nuts and screw members, creating a nested arrangement where smaller components (nuts, screw members) are positioned within the larger block. This nesting approach optimizes space utilization and reduces the external dimensions required for the connection assembly.

The patent segments the block into multiple distinct through-holes, each dedicated to a specific terminal connection. This segmentation organizes the limited space into discrete, manageable zones, allowing multiple terminals to be fastened simultaneously without creating complex spatial management issues. Each through-hole provides a defined path for screw members, simplifying the arrangement of multiple terminals within constrained dimensions.

The patent utilizes the vertical dimension by positioning nuts at different heights within the block and allowing screw members to extend in the vertical direction. This dimensional approach allows multiple terminals to be arranged along the vertical axis, effectively increasing terminal density without requiring increased horizontal space, thereby simplifying space management through three-dimensional utilization.
