Bolt-Fastened Connector Assembly With Side Insertion Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors face issues with assemblability due to the bolt being caught in through holes, requiring management and storage, which complicates fitting and disassembly.
Innovation Solution
The connector design includes an insertion opening in one of the through holes, allowing the bolt to be inserted and removed easily along the fitting direction, simplifying assembly and disassembly without the need for additional management.

1Reliability
If the bolt is inserted into both through holes for fastening, then electrical connection between conductive members is achieved, but the bolt cannot be removed without disassembly, degrading assemblability
Solution Approach 1:
The through hole is segmented into two parts: a first through hole in the first conductive member and a second through hole in the second conductive member, with the bolt passing through both. The insertion opening is provided only in the second through hole, creating an asymmetric configuration that allows one-way insertion while maintaining secure fastening when assembled.
Solution Approach 2:
The insertion opening is provided asymmetrically in only one of the two through holes (specifically in the second through hole of the second conductive member). This asymmetric design allows the bolt to be inserted easily during assembly while preventing easy removal, yet still enables complete disassembly when needed by accessing the insertion opening.
