Rack Power Source Connector Plate Depth Difference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rack-type power source devices face challenges in optimizing the space for battery packs while accommodating connector terminals and cables, often resulting in either reduced compartment space or increased installation dimensions due to protruding connectors.
Innovation Solution
A rack-type power source device design featuring a connector plate with a side wall and a connector mount wall forming a depth difference, allowing connectors to be internally positioned within a duct space, thus maintaining spacious compartments for battery packs and preventing external protrusion, while enabling cable management within the rack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connectors protrude from the backboard to provide connection space, then connector accessibility is improved, but the overall installation space increases
Solution Approach 1:
The connector mount wall is positioned at a different depth (Z-dimension) relative to the backboard, creating a stepped configuration. This allows connectors to be accessible at the front while maintaining a compact overall depth by utilizing the depth difference between the backboard and connector mount wall, rather than requiring uniform protrusion across the entire backboard surface.
2Length of stationary object
If the backboard with connector terminals is disposed deep inside the rack, then external protrusion is prevented, but compartment space for battery packs decreases
Solution Approach 1:
The backboard structure is segmented into two distinct functional zones: a deep backboard region for housing connector terminals and a shallower connector mount wall region for battery pack access. This segmentation allows the connector terminals to be positioned deep inside the rack (preventing external protrusion) while the connector mount wall extends forward to provide adequate compartment space for battery packs.
3Volume of stationary object
If a flat backboard is used to maximize compartment space, then battery pack space is optimized, but cable management becomes difficult
Solution Approach 1:
The connector mount wall creates a depth difference that forms a cable management channel between the backboard and the connector mount wall. This three-dimensional structure provides a dedicated pathway for cable routing, making cable management easier while maintaining maximum compartment space for battery packs through the optimized stepped configuration.

AI summary
A rack type power source device includes a plurality of battery packs, a rack to house the plurality of battery packs being arranged, and a connector plate fixed to the rack at a far side in a direction in which the battery packs are inserted into the rack. The connector plate is provided with a plurality of connectors designed to be electrically connected to terminals of the plurality of battery packs. The connector plate includes a side wall that constitutes a part of a first-side wall of the rack, and a connector mount wall disposed at an inner position in the rack so as to form a depth difference from the side wall. The connector mount wall is provided with the plurality of connectors arranged corresponding to the battery packs housed in the rack.
