Busbar Holder Tool-Free Assembly via Latching Pawl
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar holders are complex to use due to the requirement of multiple bolts for securing the busbar, making them cumbersome and requiring tools for assembly and disassembly.
Innovation Solution
A busbar holder design featuring a tongue-and-groove connection and a releasable latching pawl for easy assembly and disassembly without tools, allowing for a defined linear movement between the top and bottom parts, with a positioning pin for alignment and secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple bolts are used to secure the busbar, then the busbar is held firmly in the busbar passage, but the busbar holder becomes complicated to use and requires tools for assembly and disassembly
Solution Approach 1:
The patent extracts the fastening function from the busbar holder structure itself and transfers it to a separate removable fastening element (such as a snap-fit or clip mechanism). This allows the busbar to be securely held during operation while enabling tool-free assembly and disassembly by simply removing the fastening element.
Solution Approach 2:
The patent employs dynamic fastening elements that can transition between engaged and disengaged states. The fastening mechanism includes movable components that allow easy insertion and removal of the busbar without requiring tools, while maintaining secure engagement during normal operation through elastic or spring-loaded elements.
2Reliability
If multiple bolts are used to secure the busbar, then the busbar is held firmly in the busbar passage, but the number of parts and device complexity increases
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated fastening element. Instead of using multiple separate bolts, the design combines securing, positioning, and locking functions into one component that can be easily attached and removed, thereby reducing the total number of parts while maintaining secure engagement.
Solution Approach 2:
The fastening element is designed to perform multiple functions simultaneously: securing the busbar in position, providing electrical insulation, and enabling easy release. This multi-functional design reduces the number of separate components needed while ensuring reliable busbar engagement.

AI summary
The invention relate to a bus bar holder having a bottom part and a top part detachably connected to the bottom part, between which, when they are connected together, at least one busbar passage is formed, wherein the top part and the bottom part have, on mutually opposite contact surfaces, sliding faces along which they bear against one another and are movable between an open position, in which the top part can be lifted off the bottom part, and a closed position, in which the top part is secured to the bottom part via a tongue-and-groove connection, wherein a releasable latching pawl secures the top part and the bottom part in the closed position. Also described is a corresponding arrangement made up of at least one such busbar holder and at least one busbar.
