Vertical Electrical Connecting Device for Compact Bus Bar Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connection devices for horizontal rows of equipment in electrical cabinets have a large width, making them difficult to install and requiring long power cables, which complicates the connection process and limits space for additional equipment.
Innovation Solution
A compact electrical connection device with conductive bars arranged vertically, where the width is equal to the distance between the lateral bars, allowing for easier access and installation next to the equipment, and featuring a configuration that allows for a higher density of electrical connectors, facilitating connections and reducing cable length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical connectors are arranged astride the conductive bar to extend on either side, then each connector can be properly positioned, but the total width of the device becomes greater than the gap between the lateral conductive bars
Solution Approach 1:
The patent repositions electrical connectors from a lateral arrangement (extending on both sides of conductive bars) to a front-facing arrangement (extending only from the front face). This dimensional change allows connectors to be properly positioned and accessible while keeping the device width compact and equal to the gap between lateral conductive bars.
2Length of stationary object
If the device width is reduced to equal the gap between lateral conductive bars, then the device becomes more accessible and space is freed up, but the number of connectors that can be accommodated is limited
Solution Approach 1:
By changing the connector arrangement from lateral extension to front-facing extension, the patent enables multiple connectors to be stacked vertically on each conductive bar within the compact width. This dimensional reorganization allows high connector density without increasing device width.
Solution Approach 2:
The patent groups multiple electrical connectors onto single conductive bars, merging multiple connection functions into a compact vertical arrangement. This allows a high number of connectors to be accommodated within the limited width by consolidating connector positions.
3Loss of time
If connectors are arranged in a compact vertical configuration, then connection time is reduced and installation is simplified, but the connector density must be increased
Solution Approach 1:
The patent segments the electrical connection function by providing multiple connectors on each conductive bar, allowing parallel connection operations. This segmentation enables simultaneous connection of multiple equipment units, reducing total installation time despite the complex vertical arrangement.
Solution Approach 2:
The vertical stacking of connectors creates a compact configuration that reduces the horizontal space needed for cable routing and connector access. This dimensional change simplifies installation by bringing all connectors within easy reach on the front face.

AI summary
The device has two lateral bus bars (110, 140) respectively comprising the electrical connectors (111, 121A, 131A, 131B, 141A, 141B) for electrical connection of an electrical equipment to a power grid. The electrical connectors of the lateral bus bars and bus bars (120, 130) of row are arranged in a space between the lateral bus bars. The connection sub-assemblies (150A, 150B, 160) include electrical connectors that are aligned in side by side in a transverse direction (Y), perpendicular to a longitudinal axis (X) and taken in a mid-plane (P) of the bus bar row.
